Notes around the box-type substation enclosure

The shell of the box-type substation is mainly cooled by natural wind circulation. Therefore, it is not allowed to pile up illegally around it, especially the transformer room door should not be blocked, and the attachments on the louver vents should be removed frequently to ensure that all electrical equipment does not exceed the maximum allowable temperature. After the low-voltage circuit breaker is tripped, the cause of the trip should be checked before trial delivery. If the transmission is unsuccessful, the cause of the failure must be thoroughly searched, and the power can be transmitted after the removal to prevent the accident from expanding. Zinc oxide lightning arresters should be installed in the high-voltage distribution room of box-type transformers, and the installation method must be convenient for testing and disassembly and replacement.
