Analysis of common faults in the main circuit The main circuit is mainly composed of three-phase or single-phase rectifier bridge, smoothing capacitor, filter capacitor, IPM inverter bridge, current limiting resistor, contactor and other components. Many of these common faults are caused by electrol
1 structureThe core part of the three-phase oil-immersed transformer is composed of a closed iron core and windings wrapped around the iron core posts. In addition, there are oil tanks, oil conservator cabinets, casings, breathers, explosion-proof pipes, radiators, tap changers, gas relays, thermome
The winding is the heart of the transformer and the core of the transformer transmitting and converting electrical energy. Reliable winding insulation is the basic guarantee for the long-term safe operation of the transformer. Winding insulation becomes particularly important for high voltage transf
Transformer impulse voltageTransformer Impulse Voltage refers to the transient high voltage pulse suddenly applied to the transformer insulation system due to changes in weather conditions, lightning strikes, etc. in the power system. This pulse voltage has very high peak voltage and fast rise time
Among the losses of the transformer, there are mainly two parts: iron loss and copper loss. So, what is the difference between the iron loss and copper loss of the transformer?The iron loss of the transformer is the loss caused by the iron core in the transformer, and the copper loss of the transfor
