The invention relates to a breaker arc extinguishing system. The system comprises an arc extinguishing cover as well as a first arc extinguishing piece, second arc extinguishing pieces and a bent arc extinguishing piece which are arranged in the arc extinguishing cover, wherein the first arc extinguishing piece is arranged at the arc striking end of the arc extinguishing cover, the second arc extinguishing pieces are arranged on the rear side of the first arc extinguishing piece, and a bulge is formed in the first arc extinguishing piece and used for adjusting the distance between the first arc extinguishing piece and an arc striking piece of a fixed contact of a breaker. According to the breaker arc extinguishing system, the bulge is formed in the first arc extinguishing piece, so that the gap between the first arc extinguishing piece and the arc striking piece of the fixed contact of the breaker can be controlled in the optimum size range, the electric arc striking and extinguishing speed generated by the arc extinguishing system at the fixed contact is increased, and the safety performance of the breaker system is enhanced.
Description
technical field [0001] The invention relates to the field of electrical switch accessories, in particular to an arc extinguishing system for a circuit breaker. Background technique [0002] The arc extinguishing system is mainly used to interrupt or extinguish the arc generated when the current-carrying contacts are disconnected. It is mainly installed in the circuit breaker or motor protection short-circuit switch. The arc extinguishing chamber of the arc extinguishing system is usually equipped with multiple flat plates according to a certain distance. The flat arc extinguishing sheet is a metal sheet. The flat arc extinguishing sheet mainly absorbs the arc on the static contact. However, the arc extinguishing systems in the prior art all use flat arc extinguishing sheets. It is usually difficult to maintain the optimal distance between the flat arc extinguishing sheets and the arc starting sheets of the contacts, resulting in the arc extinguishing system The arc extingui...
