Arc extinguishing chamber structure of a circuit breaker or a disconnecting switch

Abstract

The present invention relates to the technical field of low-voltage electrical equipment, and discloses an arc extinguishing chamber structure of a circuit breaker or a disconnecting switch. The whole adopts a plug-in structure assembly, a number of internal grid plates are arranged in an undulating manner, a variable curved surface formed by bottom surfaces thereof is designed to match an arc elongation process, and a thickness of each grid plate gradually becomes thinner from thick along an arc elongation direction. An assembly method of the arc extinguishing chamber structure of the circuit breaker or the disconnecting switch is also provided. The arc extinguishing chamber structure of the present invention has strong versatility, good practicality, a simple overall structure, and is easy to promote and apply.
