HARD TO BURN HIGH VOLTAGE PARALLET CAPACITOR

The utility model relates to a hard-to-burn high-voltage parallel capacitor used for the reactive compensation of a high-voltage electric power system. A metallic closed container is arranged out of the hard-to-burn high-voltage parallel capacitor, and a capacitor unit assembly, a protective device and a radiator are arranged in the hard-to-burn high-voltage parallel capacitor. Fire-retardant insulating gas (such as SF-[6] and N-[2]) are inflated in the capacitor unit assembly, the protective device and the metallic closed container. The hard-to-burn high-voltage parallel capacitor has compact structure, small size and complete functions, and the hard-to-burn high-voltage parallel capacitor is hard to burn and explode, and the space of the capacitor can be reduced in a large compensation station for saving area occupation. The hard-to-burn high-voltage parallel capacitor is suitable for a power supply system with the voltage of 3-60KV in city electric network and the power supply system for preventing fire and explosion in industrial and mining enterprises.
