Document Type and Number:
WIPO Patent Application WO/2017/016364
Kind Code:
A1
Abstract:
A failure state indication device for a circuit breaker, comprising a contact group, a transmission assembly and an indication assembly which are mounted inside a housing. The contact group is realized by a normally open contact group and a normally closed contact group. The transmission assembly acts on a contact support member (107), so as to realize different open and closed states of the contact group via the contact support member. The indication assembly indicates a failure state, and the indication assembly is linked with the circuit breaker, responds to a failure and carries out corresponding state indication. The failure state indication device for a circuit breaker has a more simple and reliable design structure, has a manufacturing process which is easier to implement, and can not only indicate the state and type of a load line failure, but also can judge the operation state of the circuit breaker by means of the contact group.
