Abstract

The present disclosure relates to a circuit breaker of a gas-insulated switchgear, and more particularly, to a self-blast circuit breaker of a gas-insulated switchgear, which reuses arc heat. A self-blast circuit breaker having a heat expansion chamber and a puffer chamber includes auxiliary intake valves which introduce a hot gas exhausted through an inside of an actuating rod, into the heat expansion chamber.

Description

technical field [0001] The present invention relates to a circuit breaker for gas insulated switchgear, and more particularly, to a self-blast circuit breaker for gas insulated switchgear which reuses arc heat. Background technique [0002] Gas-insulated switchgear (GIS) refers to a switching system in which switching units such as circuit breakers, disconnectors, transformers, surge arresters, and main Supported by plates, sulfur hexafluoride (SF6) gas, which is an insulating medium with excellent insulation and arc extinguishing properties, is filled inside the cabinet and then sealed. [0003] The main withstand voltage components of GIS include gas circuit breakers, grounding switches, lightning arresters, voltage transformers, current transformers, etc. [0004] The operating procedures for circuit breakers used in GIS are specified in IEC standards. In general, the nominal operating sequence 'O-0.3s-CO-3min-CO' is followed. [0005] Basically, in the circuit breaker...
