Embodiment Construction
[0013] Can not disassemble and debug the embodiment of synchronous circuit breaker, such as figure 1 As shown, the synchronous circuit breaker capable of debugging without disassembly includes a crank arm 11, a crank arm box 12, an insulating pull rod 13, and a length adjustment mechanism.
[0014] The crank arm 11 is assembled on the crank arm box 12, and the structure and assembling method of the crank arm 11 are in the prior art, and will not be repeated here.
[0015] In this embodiment, the length adjustment mechanism is connected between the insulating pull rod 13 and the turning arm 11. The length adjustment mechanism is specifically a screw nut length adjustment mechanism, which includes a double-ended screw 14 and two ends of the double-ended screw 14 Nut 15, one of the two nut nuts is connected to the insulating pull rod 13, the other is connected to the arm 11 through a joint 16, and the arm 11 is connected to the joint 16 by a hinged way, through a forward or reverse ro...

The invention relates to the field of high-voltage switches, and particularly relates to a circuit breaker enabling synchronism debugging without disassembly. The circuit breaker enabling synchronism debugging without disassembly comprises a crank arm, a crank arm box and an insulated pull rod. A length adjusting mechanism is arranged between the crank arm and the insulated pull rod or on the insulated pull rod. The crank arm box is provided with a hand hole used for operating the length adjusting mechanism, and the hand hole is blocked by a corresponding sealing cover. According to the circuit breaker enabling synchronism debugging without disassembly of the invention, the length adjusting mechanism is arranged between the crank arm and the insulated pull rod or on the insulated pull rod, and the crank arm box is provided with the hand hole used for operating the length adjusting mechanism. Therefore, after circuit breaker assembly, the synchronism of the circuit breaker can be debugged only by opening the hand hole and elongating or shortening the length adjusting mechanism, and the assembled circuit breaker does not need to be dissembled. Thus, the problem that the efficiency of circuit breaker assembling and debugging is low is solved.
Description
Technical field [0001] The invention relates to the field of high-voltage switches, in particular to a circuit breaker that can be debugged without disassembly and synchronization. Background technique [0002] In high-voltage switchgear, circuit breaker equipment has been widely used in the power industry due to its strong breaking performance, reliable operation, long maintenance cycle, and low environmental impact. As a main parameter to measure the performance of circuit breakers, synchronicity has always been an important issue that plagues product performance during the production and debugging of circuit breakers. [0003] At present, the main method to ensure the synchronism of the circuit breaker is to improve the length and assembly accuracy of the insulation rod between the three phases of the circuit breaker. However, this adjustment method often fails to achieve the expected effect. There are still quite a few circuit breakers in the assembly and debugging process. Th...
