According to the power of protected motor and motor, use the difference in field; can select to excise conducting strip; weld the overload electro-heat equipment of corresponding technical parameter; overload electro-heat equipment be placed in bimetallic element under; can make bimetallic element respond to fast the heating temp of overload electro-heat equipment, thereby when motor runs into fault, can cut off rapidly the sensitive motor of protecting efficiently of circuit.
Heater element or material that described overload electro-heat equipment is heating wire, electric hot plate or other character.
Described adjustable plate is placed in the top of bimetallic element, conveniently carries out temperature correction, improves the consistency of product.
Motor protecter operation principle:
When protected electrical equipment and electrical apparatus and equipment immediate current increasing overload; overload electro-heat equipment is heated rapidly to the bimetallic element of overload overheat protector; when bimetallic element is experienced prefabricated temperature and rapidly reversion; moving contact and fixed contact are separated; the circuit of protected electrical equipment and electrical apparatus and equipment disconnects rapidly and avoids the motor of protected electrical appliance and equipment further to damage, fast to the reflecting time of overload, stall or short circuit overcurrent protection.
Motor protecter is reasonable in design, and compact conformation volume is little, and long service life is active in one's movements, and is widely used in the overload overtemperature protection of automotive field and household appliance technical field motor.
Accompanying drawing explanation
