Description
technical field [0001] The invention belongs to equipment in the electric power industry, in particular to a fully enclosed neutral point gap grounding protection device. Background technique [0002] At present, in my country's 110KV-220KV power system, the neutral point protection of transformers mainly adopts the parallel operation of lightning arresters and protective gaps. The existing neutral point protection devices are exposed outside. The failure rate is high, it is scattered, and its performance is unstable, so that the equipment cannot guarantee normal operation. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a fully enclosed neutral point gap grounding protection device with high stability, safety and reliability, and free from the influence of the external environment. [0004] The technical solution adopted by the present invention to solve the technical problem is...
