A switching station is literally understood as an electrical place containing only pure switching equipment. It only acts as a shunt for electric energy and does not change the voltage level of the incoming and outgoing lines. It is a power distribution device equipped with power distribution incomi
Installation environment of regulated power supplyThe stabilized voltage power supply should be used indoors in a ventilated and dry place. The usage conditions are strict. The installation site should be free of gases, steam, chemical deposits, dust, greasy dirt and other explosive and corrosive me
Chapter 3: Identification, handling and prevention of short-circuit damage accidents at close outlet of transformerWith the continuous development of the national economy and industrial and agricultural production, the installed capacity of the power system is increasing day by day, and the short-ci
Transformers work on the principle of electromagnetic induction, changing voltage, connecting to the power grid, transmitting and distributing electric energy; power transformers are the core equipment of substations, with complex structures and harsh operating environments. Failures and accidents h
1. Analysis of abnormal operation of transformer(1) The transformer sound is abnormalAs soon as the transformer is powered on, there will be a buzzing sound, which is mainly due to the high-voltage magnetic flux. During normal operation, the sound of the transformer is uniform. When there are other
