Abstract

The invention relates to the technical field of grounding protection, in particular to a neutral point gap grounding protection device, which includes a fixed plate, a support column is arranged on the lower surface of the fixed plate, and a metal rod is sheathed with a fixed column near the top, and the fixed column penetrates through the lower U Gap discharge balls are installed on the top of the metal rod, slide holes are set on both ends of the lower U-shaped plate, sliding posts are set on both ends of the upper U-shaped plate, and springs are set on each sliding post to guide A lightning protection mechanism is set near the top of the rod, and an arc-shaped discharge plate is provided at the bottom of the guide rod; the neutral point gap grounding protection device, the support column and the base are conveniently fixed on the ground to prevent the outside from affecting the stability of the entire device. The lower U-shaped plate is used in conjunction with the upper U-shaped plate, and the sliding column and the sliding hole are plugged together. Under the action of the spring, the damage caused by the shock is slowed down. The gap discharge ball is used in combination with the arc discharge plate, which is convenient for gap grounding and conduction. For protection, the lightning protection mechanism cooperates with the sharp cone to prevent lightning strikes from the outside.

Description

technical field [0001] The invention relates to the technical field of grounding protection, in particular to a neutral point gap grounding protection device. Background technique [0002] The neutral point grounding protection device is widely used in the neutral point of 110kV, 220kV, 330kV, 500kV and other power transformers, so as to realize two different operation modes of transformer neutral point grounding operation or non-grounding operation, so as to avoid causing transformer failure due to system failure. The neutral point voltage is too high or the current is too large, causing damage to the transformer; [0003] The existing neutral point gap grounding protection device is not simple enough, and the gap grounding device cannot slow down the damage caused by the shock. Contents of the invention [0004] The object of the present invention is to provide a neutral point gap grounding protection device to solve the problems raised in the above-mentioned background...
