The mining explosion-proof mobile substation (referred to as the mobile substation) consists of mining explosion-proof high-voltage vacuum switches (referred to as high-voltage vacuum switches) for mobile substations, mining explosion-proof dry-type transformers (referred to as dry-type transformers) for mobile substations, and mining explosion-proof low-voltage protection boxes (referred to as low-voltage protection boxes) for mobile substations.

The distribution method of KBSGZY mining explosion-proof mobile substation adopts the power supply load of the mobile substation. In case of faults such as short circuit, overload, undervoltage and leakage, the signal feedback is obtained through the low-voltage protection box and sent to the high-voltage vacuum switch to drive the high-voltage side circuit breaker to open. If the dry-type transformer itself fails, it can also be protected by the high-voltage vacuum switch without cutting off the upper level distribution equipment. The high-voltage side of the mobile substation has current, voltage and fault display; Due to the interruption of high voltage, the current is smaller than that of low voltage, overcoming the weakness of the original mobile substation load side fault that can only be protected by the low voltage feeder switch, and the high voltage switch is only an isolation switch. Dry type transformers are required to be explosion-proof for mining, with small volume, low loss, low impedance, and strong ability to withstand short-circuit mechanical forces.

The main performance parameters of this product are reasonably selected, which is beneficial for both power supply and product reliability. It is superior to similar foreign products and leads the domestic market, filling the domestic gap and replacing imports.
