The power transformer is an electromagnetic component. It is static electrical equipment that transforms alternating current and is widely used in almost all electronic products. It is used to change the power generated by the power station to high voltage and reduce the loss during transmission, so as to facilitate long-distance power transmission.

The function of the power transformer:

The functions of the power transformer can be divided into the following three main functions: voltage conversion, power transmission, and insulation isolation.

Principle of power transformer:

The principle of the transformer is the electromagnetic induction to transmit signals from one circuit to another circuit; the coil connected to the power supply, which receives AC power, called the primary winding; the coil connected to the load, which sends AC power, is called the secondary winding.

Structure of power transformer:

The structure of the transformer is composed of iron core and winding. The main magnetic circuit of the transformer is composed of an iron core, and the iron core is divided into two parts of the iron core column and the horizontal piece. The circuit part of the transformer is formed by winding the enameled original wire or double-wire insulated flat wire.

Classification of power transformers:

According to usage: power transformer; special transformer; instrument transformer; test transformer.

Divided by winding form: double winding transformer; three winding transformer; autotransformer.

According to the form of iron core: core transformer; bright transformer; amorphous alloy transformer.

Divided by the number of phases: single-phase power transformer; three-phase power transformer.

Divided by cooling method: dry-type power transformer; oil-immersed power transformer.

According to the size of the transmission power: 132kv transformer；10kv transformer above is high power; 10KVA~0.5KVA is medium power; 0.5KVA~25VA is low power; 25VA below is micropower.

Purpose of power transformer:

The electric power equipment can be stepped up or stepped down. When implementing the long-distance transmission of power, the power transformer is used to increase the voltage to the point of use and then reduce the voltage to the required voltage amplitude. The iron core in the transformer can produce an alternating magnetic field.

The key factors for determining signal connectors in industrial applications include: cost, environment, vibration, connector density, signal integrity, installation method, and safety requirements.

Where are the signal transmissions in industrial and semi-industrial environments? Everywhere. Devices such as sensors, actuators, switches, valves, and cameras all require signal connections to perform control and monitoring processes. As more and more smart devices are added to factory production, safe and reliable connections become more important. Modern devices must handle a variety of functions and ensure more efficient, reliable, and safe operation.

The environment around the signal connection often affects the reliability of the signal. These factors include: dirt, moisture, oils, chemicals, high and low temperatures, and ultraviolet and ozone, which must be considered in the selection of materials and sealing capabilities. In addition, electromagnetic interference (EMI) from nearby drives, motors, and other noise-generating equipment should also be considered. Without proper shielding, signal loss or unreliable signal transmission may result. Using connectors and cables to provide end-to-end signal shielding will eliminate electromagnetic interference and ensure signal integrity.

Many connections in industrial applications are exposed to mechanical shock and vibration. This impact on connector contacts, wire ends, or PCB solder joints can cause signal loss. When selecting connections for high-strength vibration applications, it is necessary to verify the connector design of anti-vibration structural elements, such as: locking threads or mechanical latches, radial O-rings, mounting flanges, fixing screws and spring technology.

Every application requires a reliable connection, and signal integrity may be destroyed by any breakpoints along the line. In addition to the wire end to the contact, the quality of the contact material is the most important factor affecting performance. When evaluating contact designs, the use of gold plating should be determined. Gold is a precious metal with good electrical properties and is not affected by corrosion. Preventing contact corrosion and having a high mating contact force are two key reasons for using gold plating in industrial applications.

Quick connection is also necessary for equipment installation, especially when the job requires a large number of connections. The shortest installation time can reduce the total cost. The connection is usually located in an inconvenient area or in a place with poor lighting. Finger fatigue and incorrect fastening will affect the success of rapid installation. By designing quick connection devices, such as spring cages or insulation displacement contacts (IDCS), at the PCB end, some of these problems can be prevented. On site, these devices provide quick plug connections, including half-turn technology or push-pull connections. When the equipment connection requires on-site wiring, the use of external connection, IDC or spring connection can save a lot of time. Because these technologies can achieve more connections in a shorter time. Research has proved that some IDC connectors can save 60% of the installation time. Compared with traditional screw joints, spring contact connectors can save 80% of the time.

Eliminating potential connection errors is a major concern for end users and field technicians, but equipment manufacturers and engineers can prevent potential erroneous connection factors during the design phase. When multiple connectors in the same space are used in a device, connector keying can eliminate confusion and effectively prevent users from inserting the wrong connector into the wrong socket. For example, in a typical signal connection scheme, engineers can select circular connectors with keyed changes, including: A, B, C, D, S, T, X, or Y. The terminal module connector can also be keyed in several modes to ensure that only the correct plug can be matched with the appropriate socket.

Marking and color coding can also reduce false matches. The most common mistakes made by technicians in the field are misconnections. Incorrect line terminals and incorrect terminal assignments may delay system commissioning and equipment startup. The use of color coding or other indicator marks on all line connection points can eliminate confusion and reduce the time spent troubleshooting on site.

When selecting signal connections for industrial applications, many variables that affect performance must be evaluated, including: cost, environment, vibration, connector density, signal integrity, installation method, and safety requirements. High-quality industrial connectors will help to ensure that terminal devices comply with international standards and provide safe and durable performance.

INDUSTRY & SOLUTION

Sunkye is a global solutions provider of connector solutions and differentiated products to the world-wide interconnector industry.

The Sunkye connection forms of industrial electrical connectors can be roughly divided into four types, and more types are currently used. Here are four of them:

Threaded connection
Some types of connections are commonly used for contacts with larger dimensions and electrical connectors that operate in high vibration environments. This type of connection can be equipped with a fuse to prevent loosening after the connection is completed. The connection is reliable, but the connection is slow.

Bayonet connection
This is a reliable and fast form of connection and disconnection. Most electrical connectors in the form of a card 121 connection have a visual display of proper connection and locking, and can be seen through a small hole on the side of the electrical connector's connection nut.

In-line connector
This is a versatile form of connection. When the plug and socket of the electrical connector are connected and disconnected, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only requires a small working space to complete the loading and unloading. Common plug-in connections come in spherical or pin configurations. Because there is no mechanical labor-saving mechanism in the connection form, once it is inserted incorrectly, the mechanical resistance increases significantly and can be found in time.

Electrical connector cabinet connection
This is an electrical connector used on some devices and requires a blind connection near the frame. It can make electrical equipment lighter, smaller, easier to maintain and more reliable.

This type of connection prevents the operator from feeling the connection. It is necessary to design an accurate positioning device to avoid forcibly connecting the wrongly inserted electrical connectors together, so that the wrong insertion cannot be performed. Cabinet-type electrical connectors are usually designed with floating or resilient contacts to ensure proper connection.

There are four common electrical grounding methods:

1.Working Grounding

Working grounding, also known as system grounding, is grounding a certain point of the network according to the needs of the normal operation of the power system. For example, the neutral point of three-phase system is grounded to stabilize the potential of the grid to the ground, thus reducing the insulation to the ground. It can also make the flashover or breakdown of ground insulation easy to detect, and is conducive to the implementation of relay protection measures.

2. Protective grounding

Protective grounding is also called safe grounding. The metal case of electrical devices, the structure of distribution devices and the tower of transmission lines may be charged due to insulation damage. The grounding is set up to prevent it from endangering the safety of people and equipment.

3. Lightning Protection and Grounding

This is to make the strong lightning current safely into the ground, to reduce the potential rise caused by the outdated lightning current, such as lightning rod, lightning wire and arrester grounding.

4.Antistatic Grounding

Grounding is designed to prevent the dangerous effects of static electricity on flammable and explosive substances such as flammable oil, natural gas storage tanks and pipelines.

Generally speaking, the function of grounding can be divided into two parts: The one protecting personnel and equipment from damage is called protective grounding; The one ensuring the normal operation of equipment is called working grounding. The classification here refers to various requirements considered in the design and construction of grounding engineering, and does not mean that each "ground" needs to be separated. On the contrary, in addition to the special reasons such as anti-interference of geoelectric signals and special requirements of equipment itself, we advocate the joint grounding scheme as far as possible.

With the increasing demand for high-density connectors in the medical market, the irreversible trend of connectors in the medical field is becoming smaller, lighter and more ergonomic. This trend strongly drives demand growth.

High density connectors are connectors with large numbers of individual contacts such as PIN pins in a relatively small connector body. There is no clear boundary between standard connectors and high density connectors, but the designation of high-density connectors is usually defined by having more contact points in the same shell size.

The growth demand for high density electrical connectors is driven by many factors, especially the size, weight and function requirements. Component size and weight have long been a key factor in many military and aerospace applications. With the increasing popularity of portable and patient wearable devices, connectors are becoming more and more important in the medical market.

In order to meet the growing demand of the higher density connector market, many manufacturers are developing standard and ready-made high density connectors solutions. When connectors need to meet a specific application and the output is limited, this solution is effective and feasible.

However, the development of standard high-density connector products will be targeted. Connector manufacturers must consider a variety of characteristics when developing to meet a wide range of application needs and budget constraints. Mature connector manufacturers with industry-leading ideas can successfully use this strategy, but this strategy is not universal.

High density connectors will continue to develop, and the trend of products will be towards miniaturization, high precision and hybrid functions. With the gradual realization of these product technologies. Engineers will surely develop new connection technologies to further improve contact density, size, weight, performance and function, and to further ensure product reliability and safety. Standards and customized solutions will greatly meet the growing demand for high-density electrical connectors in the medical market.

It is mainly used for insulation protection of electrical equipment conductors at electrical connection, as well as insulation protection for special parts such as high and low voltage switchgear, circuit breakers, rubber junction box and busbar connection box processing, and transformer terminals.

The Characteristics of silicone electrical insulation Product

1. Heat and Cold Resistance

Since silicone rubber has high bond energy and good chemical stability, its heat resistance is better than that of organic polymers. Furthermore, since the intermolecular interaction force is weak, the glass transition temperature is low and the cold resistance is also good. Therefore, its properties will not change when used in any part of the globe.

2. Waterproof

Since the surface of the polysiloxane is a methyl group, it is hydrophobic and thus can be used for waterproofing.

3. Electrical Performance

Since the number of carbon atoms in the silicone rubber molecule is less than that of the organic polymer, the arc resistance and the electric leakage resistance are very good. In addition, even if it burns, it forms silicone insulation, so it is excellent in silicone electrical insulation.

4. Weather Resistant

Since the siloxane bond energy is larger than the ultraviolet ray energy, aging due to ultraviolet rays is less likely to occur. In the ozone-resistant accelerated aging test, the organic polymer is cracked due to aging in a matter of seconds to several hours. However, even after aging for 4 weeks, the silicone rubber only slightly decreased in strength and did not cause cracking, that is, its ozone resistance was good.

The Use of Silicone Electrical Insulation

1. For Outdoor Cable Accessories

Since it is a cable accessory for outdoor use, the silicone rubber insulators must have trace resistance. By using a polymer having a cross-linking density adjusted, a material having a low permanent elongation property can be obtained for use in a product which shrinks at a normal temperature (low-temperature shrinkage).

2. For Indoor Cable Accessories

Since it is a cable fitting for indoor use, it is unlikely to be affected by salt spray, so it is often unnecessary to have a trace of leakage resistance. In the case of shrinkage at room temperature (low temperature shrinkage), it is still necessary to have low permanent deformation characteristics.

3. For Coating

If a silicone rubber coating is applied to a heavily contaminated part, good hydrophobicity can be maintained for a long period of time. The installed insulators can also be coated according to the degree of pollution to achieve the purpose of continued use and cost saving.
