Dry type electrical transformers producing company from China

Dry type power transformer supplier factory from China: Power quality plays a crucial role in the performance and longevity of distribution transformer substation. Poor power quality can lead to increased losses, reduced efficiency, and shorter equipment lifespan. Therefore, effective strategies for power quality management are indispensable for the optimal operation of distribution transformers. Harmonic currents, particularly those of higher frequencies, can significantly affect the performance of transformers. These currents are produced by non-linear loads such as computers, variable speed drives, and certain types of lighting systems, causing distortions in the sinusoidal waveform of the electrical supply.

As one of the best dry type transformer manufacturers & suppliers in China, Canwin specialized in dry type power transformer manufacturing for over 20 years.Our dry transformer is widely used in local lighting, high-rise buildings, airports, terminals CNC mechanical equipment and other places, simply said dry type transformerrefers to the core and winding are not impregnated in the transformer insulation oil.There are two main types of dry type transformers: cast resin dry type transformer (CRT) and vacuum pressure impregnated transformer (VPI).

The transformer coils are referred to as the primary and secondary windings. When applying AC current to the primary winding of the transformer, the transformer coil creates a pulsing magnetic field. The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy.The machine is a very powerful and versatile machine which can wind a wide range of HV coils for distribution transformers using round and rectangular wires. It is fully automatic with paper strip winding.Winding material lnsulated with an epoxy resin -environmentally friendly.

Why does the current source inverter need a larger transformer capacity? Current source inverter is a common type of inverter. Its control method adopts current loop control, which has the advantages of high precision and strong adaptability, and is widely used in industrial production. Due to the working characteristics of the current source inverter, a large transformer capacity is required for the following reasons: The current source inverter adopts the intermediate inductance: the current source inverter adopts the intermediate inductor, which can realize the phase difference between the output voltage and the current, so as to realize the frequency conversion control. However, since the intermediate inductor needs to withstand large current and voltage, it is necessary to select a transformer with a larger capacity to ensure the normal operation of the inductor.

Epoxy resin is non – combustible, flame retardant, self – extinguishing solid insulation material, safe and clean. It is also a solid insulation material with proven insulation and heat dissipation technology for more than 40 years.Epoxy resin products can be used for dry type transformer, for insulation parts, for instrument transformer, for electrical composite parts and for room temperature curing. Epoxy resin dry transformer uses epoxy resin as insulation material. The high and low voltage windings are made of copper tape (foil), industrial epoxy resin is poured in vacuum and cured, forming a high strength FRP body structure. Insulation grade F, H. Epoxy resin dry transformer has the characteristics of good electrical performance, strong resistance to lightning impact, strong resistance to short circuit, small size and light weight. Temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.

As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. Read even more information at canwindg.com

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.

Connection group label: According to the phase relationship between the primary and secondary windings of the transformer, the transformer windings are connected into various combinations, which are called the connection group of the windings. In order to distinguish different connection groups, the clock notation is often used, that is, the phasor of the line voltage on the high-voltage side is used as the long hand of the clock, fixed at 12, and the phasor of the line voltage on the low-voltage side is used as the short hand of the clock. The number of the short hand indicates the connection group label. For example, Dyn11 indicates that the primary winding is (triangle) connected, and the secondary winding is (star) connected with a center point, and the group number is (11) points.

What does the rated value on the nameplate of the transformer mean? The rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer. Usually includes the following aspects: Rated capacity: The rated capacity of a transformer refers to the maximum load electric power that the transformer can continuously supply. For example, a 10MVA transformer means that the transformer’s maximum load can reach 10 megawatts. Rated voltage: The rated voltage of the transformer refers to the design voltage of the transformer. For example, a 220kV/110kV transformer means that the input voltage of the transformer is 220 kV and the output voltage is 110 kV. Rated frequency: The rated frequency of a transformer refers to the power frequency for which the transformer is designed. In China, the power frequency is usually 50Hz. Short-time withstand current: The short-time withstand current of a transformer refers to the maximum current value that the transformer can withstand in a short period of time. For example, the short-term withstand current of a transformer is 50kA, which means that the transformer can withstand an instantaneous current of up to 50 kA.
