Embodiment Construction
[0038] The content of the present invention will be further described below in conjunction with the accompanying drawings.
[0039] Such as Figure 2-5 As shown, the mechanical interlocking structure 1 of the circuit breaker of this embodiment is arranged between two circuit breakers 2, and the closing of the two circuit breakers 2 is controlled by the mechanical interlocking structure 1, so as to avoid the problems caused by the simultaneous closing of the two circuit breakers 2. Security risks.
[0040] Described mechanical interlocking structure 1 comprises:
[0041] A deflection member 11, the deflection member 11 is rigidly connected to the closing semi-axis 21 of a circuit breaker 2, and the deflection member 11 deflects along with the closing semi-axis 21 of the circuit breaker 2 when the circuit breaker 2 is closed;
[0042] The blocking member 12 is driven by the driving shaft 23 of another circuit breaker 2, and when the other circuit breaker 2 is closed, the drivi...

The application relates to the field of circuit breakers, and in particular to a mechanical interlocking structure and a mechanical interlocking device of circuit breakers. The mechanical interlockingstructure of circuit breakers is disposed between two circuit breakers and comprises a deflecting member and a blocking member, wherein the deflecting member is rigidly connected to a closing half shaft of a circuit breaker and deflects with the closing half shaft of the circuit breaker when the circuit breaker is closed; the blocking member is driven by the driving shaft of the other circuit breaker, and the driving shaft drives the blocking member to be adjacent to the deflecting member to prevent the deflecting member from deflecting when the other circuit breaker is closed. The problem inthe prior art that the mechanical interlocking structure existing is complicated and the precision requirement is high is solved.
Description
technical field [0001] The present application relates to the field of circuit breakers, in particular to a mechanical interlocking structure and a mechanical interlocking device of a circuit breaker. Background technique [0002] As an indispensable main control and protection equipment in the power system, vacuum circuit breakers have a series of advantages such as high reliability, large breaking capacity, long maintenance cycle, no pollution, no explosion hazard, and suitable for frequent operations. Enterprises and other fields have been more and more widely used. [0003] In the prior art, the dual power switch is a commonly used low-voltage switching appliance, which is widely used in smelting, chemical industry, hospitals, government agencies and other occasions that require uninterrupted power supply. The switch automatically switches the power supply to the backup power supply to ensure normal power supply. However, once the two circuit breakers are switched on a...
