Abstract
A breaker joint with a temperature compensation device comprises the temperature compensation device and a joint, and the temperature compensation device comprises a shell, a heating resistor and a control device. The control device is connected with a wiring of a breaker and the heating resistor, and the heating resistor and the control device are arranged in the shell; the shell is a hollow cylindrical structure, the joint is arranged at the hollow position of the shell and comprises the breaker joint and an oil tube joint, and the breaker joint is connected and communicated with the oil tube joint. According to the utility model, the phenomenon is avoided that the breaker is difficult to open and close, and the faults of the breaker are reduced.
Description
Technical field:
The present invention relates to field of power, particularly a kind of circuit breaker joint that temperature compensation means is installed.
Background technology:
Generally speaking; every circuit breaker has the joint of 9 place's high-pressure oil pipes; the joint of high-pressure oil pipe comprises glue and metal material, because throughout the year, temperature constantly changes; the degree of expanding with heat and contract with cold of gummed metal material is inconsistent; cause the oil connection place slit can occur, so the high-pressure oil pipe joint place of circuit breaker usually fuel injection event can occur, can cause refusing minute, refusing to close of circuit breaker when oil spout is serious; if when running into failure condition, scope that can the expansion accident.
Summary of the invention:
In view of this, be necessary to provide a kind of circuit breaker joint that temperature compensation means is installed.
A kind of circuit breaker joint that temperature compensation means is installed, it is characterized in that: the circuit breaker joint that temperature compensation means is installed comprises temperature compensation means, joint, temperature compensation means comprises shell, heating resistor, control device, control device is connected with the wiring of circuit breaker, control device is connected with heating resistor, heating resistor, control device are installed in the enclosure, shell is hollow cylinder structure, jiont treatment is at shell hollow place, joint comprises circuit breaker joint, oil connection, and the circuit breaker joint is connected with oil connection and communicates.
Control device comprises air switch, temperature controller, A.C. contactor, temperature controller is connected in series with heating resistor, A.C. contactor, air switch and temperature controller also connect, and air switch is connected with the live wire L of circuit breaker, and air switch is connected with the zero line N of circuit breaker.
Heating resistor is ceramic resistor.
Shell is the hollow circuit cylinder body structure.
The present invention is installed on the circuit breaker oil pipe, the circuit breaker joint is connected with the fuel-tank outlet place of metal material and communicates, and oil connection is connected with an end of oil pipe and communicates, when temperature is down to subzero 5 degrees centigrade, temperature controller starts, the normal opened contact of temperature controller is closed, the A.C. contactor excitation, and the normal battle of A.C. contactor is closed, the ceramic resistor energising, heating, and to the place's heat supply of circuit breaker oil connection, avoided the joint of oil connection and circuit breaker the slit to occur.So, adopt the present invention, avoided the generation of refusing minute, refusing to close phenomenon of circuit breaker, reduced the generation of circuit breaker failure condition.
