Circuit breaker indicating device and circuit breaker using the same

Abstract

The invention discloses a circuit breaker indicating device and a circuit breaker using the same. The breaker indicating device comprises a manual indicator and a fault indicator, wherein the manual indicator comprises a display color plane, a rotating shaft and an external force effect plate, the display color plane is arranged at a topmost part of the manual indicator, an external force effect plate is welded between the display color plane and the rotating shaft, the fault indicator comprises a fault display color plane, a rotating shaft bottom plate and a first arc groove, the fault display color plane is arranged at a topmost part of the fault indicator, and the first arc groove is fixedly connected with the fault display color plane through the rotating shaft bottom plate. The breaker indicating device is advantaged in that manual opening and fault opening of a product can be effectively distinguished and are convenient to distinguish for operation and maintenance personnel, corresponding processing operation can be carried out according to state indication, installation is simple and convenient, and change of the overall structure of the circuit breaker is not involved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker indicating device and a circuit breaker using the device. Background technique [0002] At present, most of the specifications of miniature circuit breakers in the industry do not have the opening and closing status indication function. Some specifications have the above indication function, but there are problems such as inaccurate indication status or complex indication structure. This type has a single closing and opening indication function. The usual method for similar circuit breakers is to set a rotating structure at the swing position of the moving contact, and the rotating structure is driven by the swing of the moving contact to perform closing and opening instructions. [0003] However, the above-mentioned method of arranging ornaments on the movable contact has the following defects; [0004] 1. In the process of product operation, the stru...

Problems solved by technology

[0004] 1. In the process of product operation, the structural parts and contacts form an indirect connection, which can easily cause the failure of the indicating structural parts, causing the indicating structural parts to fail to correctly indicate the closing and opening states of the contacts, and the reliability is not high;

[0005] 2. In addition, the above-mentioned indicating device only has the indication function of two states of closing and opening. If there is a short-circuit protection opening in the line, if it is not distinguished whether it is a fault trip or a manual opening, it will not be used. Proper closing action is very dangerous;

In the scheme of the reference document 2, due to the connection between the structural member and the contact, it may cause the failure of the indicating structural member
