Abstract
The utility model discloses an operating state monitoring device for a small breaker, the operating state monitoring device comprises a breaker body, wherein the two ends of the fixed contact of the breaker body are connected with indication lamps in parallel. The operating state monitoring device has the advantages that the structure is simple; the use effect is good; and through observing the brightness of the indication lamps, the operating state of a breaker can be judged, so that the breaker can be timely replaced, and the safety accidents caused by electricity consumption can be reduced.
Description
Technical field
The utility model relates to a kind of circuit breaker, especially relates to a kind of miniature circuit breaker running state monitoring device.
Background technology
Because miniature circuit breaker has advantages such as practicality, convenience, safety, miniature circuit breaker in each appliance field and people's production, live in extensive use.But; In use owing to load and circuit breaker do not match; Occur that overload operation, band heavy load are operated a switch, phenomenon such as spontaneous corrosion causes the breaker contact point contact resistance value to increase in environment; Circuit breaker is moved in spite of illness, cause very big potential safety hazard therefore for our production, life.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of simple in structure, miniature circuit breaker running state monitoring device that result of use is good.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of miniature circuit breaker running state monitoring device, it comprises breaker body, the fixed contact two ends of breaker body are parallel with indicator light.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This miniature circuit breaker running state monitoring device, it is simple in structure, and is reasonable in design; Be easy to realize that result of use is good, at the fixed contact two ends of breaker body parallel connection indicator light; Brightness through viewing lamp; Can judge the running status of circuit breaker,, reduce the security incident of bringing because of electricity consumption so that in time change.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-breaker body; The 2-indicator light.
Embodiment
Through accompanying drawing and embodiment the utility model is done further explain below.
As shown in Figure 1, this miniature circuit breaker running state monitoring device, it comprises breaker body 1, two groups of fixed contact two ends of breaker body 1 all are parallel with indicator light 2.
When voltage one regularly, the inversely proportional functional relation of electric current and resistance, promptly in circuit, electric current is big in the little branch road of resistance, electric current is little in the big branch road of resistance.When the contact resistance of circuit breaker was very little, electric current can preferentially be selected to arrive electrical appliance through the contact; When the resistance of contact increases or during near the resistance of indicator light, indicator light can be lighted, and therefore, can judge the running status of circuit breaker through the brightness of viewing lamp.
