First, to ensure that the voltage of each connection group in the box transformer is always the same, the double power consumption of the box transformer should be the same, and when the impedance voltage is the same, two parallel box transformers should be used, and the power supply voltage should be strictly controlled.
Secondly, when the box transformer is out of power, the low-voltage end should be cut off first, followed by the high-voltage end, and finally the high-voltage end should be cut off. When conducting electricity, the grounding switch should be turned on first and then discharged.
Third, do a good job in the maintenance of box transformers. Firstly, insulating shoes and gloves should be worn when maintaining and repairing box transformer; secondly, the outer shell of box transformer www.xinhaogan.cnwww.hejinwantou.com.cnwww.jiankonggan.org.cn www.jiankongligan.org.cnshould www.wushuichul.cnwww.banjiatangshan.cnbe cleaned on time, and whether there are cracks or aging lines in the outer shell should be checked; thirdly, in order to ensure that box transformer has a good ventilation environment, the accessories around box transformer should be cleaned regularly; lastly, safety should be ensured. When installing and maintaining box transformers, it is necessary to check strictly whether all the interfaces, screws and connecting wires are installed rigorously.
