Excellent dry type electrical transformers supplier: When is it not allowed to adjust the tap changer of the transformer on-load voltage regulating device? The on-load voltage regulating device is a common accessory equipment of the transformer, which is used to adjust the transformation ratio when the transformer is running, so as to achieve the purpose of adjusting the output voltage. When using the on-load pressure regulator, the following points need to be paid attention to: It is not allowed to operate under live conditions: because the transformer is working under live conditions, the tap changer of the on-load voltage regulating device will have an arc when it is adjusted, so it is not allowed to operate the tap changer under live conditions. Frequent adjustments are not allowed: frequent adjustments to the tap changer of the on-load tap changer may cause damage to the tap changer or poor contact, thereby affecting the normal operation of the transformer.

Current source inverter has a higher power factor: The current source inverter has a higher power factor, which can achieve higher power factor correction, thereby reducing grid harmonic pollution. However, since a higher power factor requires larger capacitor support, a transformer with a larger capacity needs to be selected to meet the power supply requirements of the capacitor. Current source inverter needs additional power supply: The circuit of current source inverter needs additional power supply to ensure the normal operation of the current loop control. These additional power sources need sufficient capacity to support, so a transformer with a larger capacity needs to be selected to meet the power supply requirements. Therefore, the current source inverter needs a larger transformer capacity to ensure the normal operation of the intermediate inductor, support the power supply of the capacitor and meet the power supply requirements. When selecting a transformer, it needs to be selected according to the actual electrical parameters and performance requirements to ensure the normal operation and stability of the inverter.
When these harmonic currents flow through a transformer, they can cause increased core losses due to hysteresis and eddy currents. Hysteresis loss is related to the magnetization and demagnetization of the transformer’s core material in response to the alternating current. Eddy current loss occurs when induced currents circulate within the core material, creating local magnetic fields that oppose the main field. Both these losses increase with the frequency of the current. Thus, higher frequency harmonic currents can lead to considerably higher core losses, reducing the transformer’s efficiency and causing it to overheat, which can shorten its lifespan.

Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.
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.
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 more information at https://www.canwindg.com/

As a professional energy storage system manufacturer, Canwin specialized in battery energy storage system and containerized energy storage system manufacturing. An energy storage system, often abbreviated as ESS, is a device or group of devices assembled together, capable of storing energy in order to supply electrical energy at a later time. In the energy storage systems, the lithium energy storage battery only interacts with the energy storage converter at high voltage, and the converter takes power from the AC grid to charge the battery pack. Or the battery pack supplies power to the converter, and the electric energy is converted into AC by the converter and sent to the AC power grid.
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.
