Description
Technical field
The present invention relates to a kind of vacuum permanent magnet circuit breaker.
Background technology
Circuit breaker refer to the electric current that can close, carry and cut-off under normal loop condition and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition in official hour.Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application, and high-low pressure identification of boundaries is fuzzyyer, is called High-Voltage Electrical Appliances generally by more than 3kV.
Circuit breaker can be used to distribute electric energy, infrequently start asynchronous motor, protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc., and generally do not need to change parts after disjunction fault current, at present, obtain a wide range of applications, the generation of electricity, conveying, in using, distribution is an extremely important link, distribution system comprises transformer and various high and low voltage electrical equipment equipment, low-voltage circuit breaker is then the electrical equipment that a kind of use has a large capacity and a wide range, the main contacts of low-voltage circuit breaker is by manual operation or electric switch-on, after main contacts is closed, main contacts is locked on closing position by free tripping mechanism, the coil of overcurrent trip and the thermal element of thermal overload release are connected with main circuit, the coil of under-voltage release and power sources in parallel, when circuit be short-circuited or heavy overload time, the armature adhesive of overcurrent trip, make free tripping mechanism action, main contacts disconnects main circuit, when circuit overloads, the thermal element heating of thermal overload release makes on bimetal leaf bending, promote free tripping mechanism action, when circuit under voltage, the armature release of under-voltage release, also free tripping mechanism action is made, shunt release is then used as far distance controlled, when normally working, its coil is power-off, when needs distance controlling, press starting button, make coil electricity.
Current existing breaker operator is inconvenient, and structural stability is poor, can not tackle emergency.
