Summary of the invention
The purpose of this utility model is to provide a kind of electric wiring controller, can protect well motor, and have superheat protecting function, prevents that motor from being burnt, safe and practical.
Electric wiring controller described in the utility model, comprise the power supply of series connection successively, thermostat, hot protective relay, motor and starter relay, switch is in parallel with power supply after connecting with illuminating lamp, wherein the Working winding of motor interior is connected with power supply again after connecting with the coil in starter relay, the second main contacts in starter relay is connected with power supply, the starting winding of motor interior is connected with the first main contacts in starter relay, sheet metal is set above coil, corresponding the first main contacts in two ends and second main contacts of sheet metal arrange the first fixed contact and the second fixed contact, hot protective relay is butterfly hot protective relay, comprise shell, portion both sides are fixedly installed respectively two metallic supports in the enclosure, a metallic support top is provided with the 3rd fixed contact, another metallic support top is provided with the 4th fixed contact, butterfly sheet metal is set above two metallic supports, at the bottom of butterfly sheet metal arrange three main contacts corresponding to the 3rd fixed contact, at the bottom of butterfly sheet metal arrange four main contacts corresponding to the 4th fixed contact, the middle part of butterfly sheet metal arranges set screw, and the 4th fixed contact connects binding post by resistance wire.
Electric wiring controller described in the utility model goes for the electric wiring of the electrical equipment such as refrigerator and controls.
During use, opening power, electric current by coil is very large, in the coil of starter relay, produce stronger magnetic field, attract the first main contacts and the second main contacts, the first main contacts and the first fixed contact are connected, the second main contacts and the second fixed contact are connected, after connection, make the starting winding of motor also switch on power, thereby motor is started to rated speed rapidly.When motor enters after normal operation, by the electric current in starter relay coil, be suddenly reduced to again motor rated current, therefore the field weakening producing, the first main contacts and the first fixed contact are disconnected, the second main contacts and the second fixed contact disconnect, the power-off of motor starting winding, motor Working winding normally moves.
Hot protective relay is butterfly hot protective relay; when operation principle is connected for electric current in circuit, the 3rd fixed contact and the 3rd main contacts are connected, and the 4th fixed contact and the 4th main contacts are connected; in circuit, electric current is excessive; electric current by resistance wire increases, and caloric value increases, and has toasted the butterfly sheet metal on top; make butterfly sheet metal because of overheated dilatancy until oppositely arch; the 3rd fixed contact is separated with the 3rd main contacts, and the 4th fixed contact is separated with the 4th main contacts, and circuit is cut off.Although or the normal running current of motor is normal sometimes, but because the bad or long-time continuous operation of dispelling the heat causes in motor temperature rise too high, case surface reaches after uniform temperature (approximately 85 degrees Celsius) afterwards, the temperature distortion of butterfly sheet metal also can arch, make the 3rd fixed contact separated with the 3rd main contacts, the 4th fixed contact is separated with the 4th main contacts, cuts off the electricity supply.Can, by regulating set screw, change the required temperature reaching of shell while arching, so there is double protection.
In sum, the utlity model has following advantage: can protect well motor, and there is superheat protecting function, prevent that motor from being burnt, safe and practical.
