If the mining circuit breaker automatically pops up, the staff must promptly take the following measures. After automatic jumping on both sides of the circuit breaker, the control circuit breaker of the high-voltage switchgear circuit breaker works in the jumped position, and the standby switch is quickly used. The main causes of fires in high-voltage switchgear are damage and deflection of the casing, oil flow under tank pressure and combustion of the top cover, and oil tank leakage caused by internal faults in the switchgear, casing, or heat sink. The ignition of the damaged switch room must turn off the switches on both sides of the switch room, cut off the power supply on both sides, and quickly enter the standby room. Then, the cooling device stops operating.

The two are located in different application environments and functions, making it difficult to compare their importance. Substation is an important infrastructure in the power system, used for energy transmission, transformation, and distribution, directly related to power safety and stability; And the substation is mainly used for small-scale power supply, suitable for some residential areas, schools and other places, and is also indispensable.

No. Although substations and substations are both electrical equipment, their application environments and functions are different. Substations are mainly used for the transmission, transformation, and distribution of electrical energy, and are an important part of the power system; And the substation is mainly used for small-scale power supply, suitable for some residential areas, schools and other places.
