The magnetic circuit is an important component of the transformer core, which is a laminated or wound structure that provides a low magnetic resistance path for the main magnetic flux generated by the excitation winding. A part of the iron core is surrounded by windings, called the iron core column;

1. Fuction:When lightning overvoltage invades a substation or other buildings along an overhead line, flashover may occur, and even the insulation of electrical equipment may be punctured. Therefore, if a protective device, namely a surge arrester, is connected in parallel at the power inlet end of

A transformer is mainly composed of the core, windings, oil tank, conservator, bushings, tap-changer, breather, pressure-relief device, radiator, Buchholz (gas) relay, oil purifier, and internal insulation. Their functions are described below:1. CoreFunction: Forms the magnetic circuit for alternat

Gas relay (also known as gas relay) is a protective device used in transformers, installed in the pipeline between the oil storage tank and the oil tank of the transformer. When the oil decomposes and produces gas or causes oil flow surge due to internal faults of the transformer, the contact of the

The connection group number and short-circuit impedance are important technical indicators of a transformer. Different connection group numbers are used in different scenarios. The connection group number is a symbol that represents the connection method of the transformer windings and the phase rel

The "smart ventilator" of the power system —— reactive power compensation deviceWhy does the power system need "reactive compensation"?If the power system is compared to the human body, active power is the "blood" to maintain the heartbeat, and reactive power is the "oxygen" to regulate the breathin
