Description
Technical field
The utility model relates to a kind of control device, is specifically related to a kind of control device of spring energy-storing mechanism of breaker.
Background technology
The use of circuit breaker very extensive, a lot of electric equipment all needs use circuit breaker, 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, conventional breaker mechanism is spring operating mechanism, this mechanism can not realize the normal electric switch-on of switch when spring unstored energy, when obstructed at mechanism motor tank circuit, spring unstored energy or assign reclosing command when energy storage is not in place, switch can not normal electric switch-on, and easily blow the closing coil of switch.In real work, repeatedly there is the situation that closing coil burns out in this circuit breaker.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the control device of a kind of spring energy-storing mechanism of breaker that switching is effective.
The technical solution of the utility model is: a kind of control device of spring energy-storing mechanism of breaker, be provided with closing circuit, described closing circuit is provided with auxiliary switch, described closing circuit is provided with contact, described contact front end is provided with contact device, auxiliary switch switch plate is provided with between described contact device and contact, described closing circuit is provided with circuit breaker, described circuit breaker is provided with energy storage device, described circuit breaker is provided with connecting lever, described connecting lever is other is connected with closing contact, is provided with contact arm between described energy storage device and closing circuit.
Described contact is divided into contact one, contact two and contact three, and described contact two and contact three are positioned at the front end of auxiliary switch switch plate, and described contact one is positioned at the front end of killer switch sheet.
Described auxiliary switch is push-button switch, and described auxiliary switch controls closing circuit, and described auxiliary switch is positioned at the right side of circuit breaker.
Described contact arm is provided with carriage, and described carriage is roller, and described roller is positioned at the downside of contact three, is provided with contact arm between described energy storage device and roller.
The utility model has the advantages that: on closing circuit, be provided with auxiliary switch; closing circuit can be made more efficient when operation; when preventing spring energy-storage from not putting in place; closing circuit is obstructed, can avoid the abnormal shutdown of electric equipment, maintains the stable of circuit; certain electric power resource can be saved; prevent electric equipment due to circuit instability, kept the normal production run that some make electrical installation enterprise, ensure that the power supply of user is normal.
