Description
Technical field
The utility model relates to a kind of permanent-magnet breakers.
Background technique
Currently, limit and resetting apparatus are not provided on existing permanent-magnet breaker, because scene is required to pulling under insulating bar
Lock handle makes breaker open operation, and sub-switching operation back handle can not reset, not only appearance unsightly, but also separating brake axis rotation period
Between, once rotation semi-circular portions go to opposite side, then when permanent magnet mechanism closes a floodgate, dynamic iron core encounters separating brake shaft, and permanent magnet mechanism is by nothing
Method is closed a floodgate, and there are great security risks；The not set limiting device of circuit breaker internal, when on-site manual operates separating brake, Wu Fazhun
Really judge that separating brake handle turns to that angle could pack the reliable separating brake of breaker, is not easy to Field Force's operation.Therefore, it designs
A kind of permanent-magnet breaker with limit and reset function is imperative.
Utility model content
The purpose of the utility model is to provide a kind of with the permanent-magnet breaker limited with reset function.
To achieve the above object, the utility model provides the following technical solutions:
A kind of permanent-magnet breaker, comprising: separating brake handle 1, separating brake axis 2, limit assembly 3, permanent magnet mechanism 4, circuit breaker housing
5, it is characterized in that: being equipped with permanent magnet mechanism 4 and limit assembly 3 inside circuit breaker housing 5, separating brake axis 2 is inserted across circuit breaker housing 5
Enter in permanent magnet mechanism 4, separating brake handle 1 is fixed on separating brake axis 2.
The separating brake axis 2 is equipped with platform A21 and hole A22.
The limit assembly 3 is made of spacer pin 31, rotational pin 32, tension spring 33 and hanging pin 34.
The spacer pin 31 and hanging pin 34 is welded in circuit breaker housing 5.
The rotational pin 32 is equipped with platform B321 and hole B322.
The hanging pin 34 is equipped with card slot 341.
The beneficial outcomes of the utility model are that circuit breaker housing 5 is equipped with spacer pin 31 and hanging pin 34, and rotational pin 32 passes through
Separating brake axis 2 is against on spacer pin 31, drives separating brake axis 2 and rotational pin 32 to control permanent magnetic motor by manual operation separating brake handle 1
4 separating brake of structure, the reliable separating brake moment of permanent magnet mechanism 4, rotational pin 32 resists the spacer pin 31 on 5 top of circuit breaker housing, Field Force
Separating brake handle 1 can not be operated again, judge convenient for Field Force and is operated, and 33 both ends of tension spring are hung in the card slot 341 of hanging pin 34
On the hole B322 of rotational pin 32, rotational pin 32 is under the restoring force effect of tension spring 33 and then drives separating brake axis 2 and separating brake handle 1
It sets back, this structural safety performance is high.
