High-voltage heavy-current transient automatic discharge switch for regulating gap by elastic vertical rod

The invention relates to a high-voltage heavy-current transient automatic discharge switch for regulating a gap by elastic vertical rods. The high-voltage heavy-current transient automatic discharge switch comprises two hollow copper balls in an isolation space, wherein the two hollow copper balls are respectively supported by insulation posts and are connected with corresponding terminals through conducting wires, the insulation post fixedly provided with an insulation rope is an elastic silica gel insulation post, the bottom of the isolation space is provided with a fixed pulley, and the side wall of the isolation space is provided with an insulation rope outlet. The insulation rope is pulled outside the isolation space, and one silica gel insulation post is inclined towards the side of the other insulation post, so that the gap of the two copper balls is reduced, and the transient discharge is realized when a certain gap is reached. The high-voltage heavy-current transient automatic discharge switch for regulating the gap by the elastic vertical rods has the advantages that the cost is low, the structure is simple, the use is convenient, and the operability is high.
