Abstract
The utility model relates to an over-current time-delay release double-metal arc ignition assembly of a miniaturized circuit breaker. The over-current time-delay release double-metal arc ignition assembly comprises a double-metal sheet, a double-metal arc ignition connection sheet and an arc ignition sheet. One end of the double-metal sheet, one end of the double-metal arc ignition connection sheet and one end of the arc ignition sheet are fixedly connected, the other end of the double-metal sheet is connected with a circuit breaker moving contact through a lead, the other end of the double-metal arc ignition arc ignition connection sheet is in cooperation connection with the circuit breaker moving contact, and the other end of the arc ignition sheet is arranged below an arc-extinguishing cover of the circuit breaker. According to the utility model, the over-current time-delay release double-metal arc ignition assembly of the miniaturized circuit breaker has the advantages of simple structure and convenient installation. Besides, the assembly also exhibits an over-current time-delay release effect for the circuit breaker.
Description
Technical field
The utility model relates to Low Voltage Electrical Apparatus, relates in particular to a kind of two golden striking sub-assemblies of overcurrent delay dropout of miniature circuit breaker.
Background technology
Circuit breaker is common Protector for electric appliances of the prior art, and confession, Electrical Safety and people's lives are played to great effect.Be often referred to the electric current that can close, carry and cut-off under normal loop condition, and can close, carrying and cut-off the switching device that abnormal loop condition comprises the electric current under short circuit condition in official hour.Can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur electrical appliance.And the two golden striking sub-assemblies of the overcurrent delay of miniature circuit breaker dropout play the effect of overcurrent delay dropout in circuit breaker as the significant components of circuit breaker.
Summary of the invention
The purpose of this utility model is to provide a kind of two golden striking sub-assemblies of overcurrent delay dropout of miniature circuit breaker, plays the object of delayed releasing.
In order to solve the problem in background technology, realize the purpose of this utility model, the utility model adopts following technical scheme:
A kind of two golden striking sub-assemblies of overcurrent delay dropout of miniature circuit breaker, comprise two gold plaques, two golden striking brace and arc striking piece, one end of two gold plaques, two golden striking brace and arc striking piece is fixedly connected with, the other end of two gold plaques is connected with moving contact of breaker by wire, the other end and the moving contact of breaker of two golden striking braces are connected, and the other end of arc striking piece is arranged on the arc-extinguish chamber below of circuit breaker.
The two golden striking sub-assemblies of overcurrent delay dropout of a kind of miniature circuit breaker that the utility model provides, simple in structure, easy for installation, for circuit breaker plays the effect that overcurrent delay is threaded off.
