Description
Technical field
The utility model belongs to switching technique field, is specifically related to a kind of Multifunction low-voltage circuit breaker.
Background technology
Multifunction low-voltage circuit breaker, everyday home circuit application very extensive, is used for when family's short circuit protecting various household electrical appliance.The structure of circuit breaker in the market comprises shell, testing circuit and actuator, actuator comprises electromagnet and trip gear, rely on electromagnet to carry out a motion of threading off to drive trip gear, when trip gear goes wrong time, although electromagnet has received overload messages adhesive, but trip gear can not produce trip action, so circuit breaker remains In the view of extraneous people be in normal operating conditions, inspection and maintenance would not be carried out to it, electrical network can be made like this to damage, and Multifunction low-voltage circuit breaker inside all needs to arrange an arc-control device therein, the electric arc produced when being used for knocking out contact separation, arc quenching principle due to arc control device is the effect distributing the heat of arc control device ambient air fast to reach arc extinguishing fast, but because case for circuit breaker is relatively closed, main dependence exhaust outlet and the external world carry out heat exchange, and that exhaust outlet can not be established is very large, otherwise electric arc can spill from exhaust outlet and burn circuit, even if but exhaust outlet establish very little, electric arc still has certain probability to spill from exhaust outlet to burn circuit, if do not establish the words of exhaust outlet, be easy to circuit breaker internal temperature is raised, circuit breaker is made to cause circuit breaker to burn out by arc extinguishing.
Utility model content
The purpose of this utility model is to provide a kind of Multifunction low-voltage circuit breaker, to solve the deficiency existed in such scheme.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of Multifunction low-voltage circuit breaker, primarily of spring, main contact, drive link, snap close, axle, magnetictrip, lever, armature, under-voltage release, bimetal leaf and heater element composition, spring is provided with on the left of described drive link, the upper and lower both sides of drive link are provided with main contact, snap close is provided with on the right side of drive link, snap close right-hand member is provided with axle, lever is connected below snap close, battery release is provided with on the left of lever, battery release upper end connects main contact lower end and connects heater element, heater element is provided with bimetal leaf, lever lower right side is provided with under-voltage release, under-voltage release is provided with armature.
Auxiliary contact is provided with on the left of described main contact.
Spring is provided with above described armature.
Described magnetictrip is provided with armature.
The utility model is equivalent to the combination of knife switch, fuse, thermal relay and under voltage relay, and collection controls to be protected in all over the body with multiple, and dress is simple, breaking capacity advantages of higher.In normal work, each release is all failure to actuate, and when circuit be short-circuited, under-voltage, overload fault time, respectively by respective release, snap close is backed down by lever, realizes protective effect.
