The invention discloses a circuit breaker handcart calibrating device and a calibration method therefor. The device comprises a contact fixing plane and a handcart rail plane, which are perpendicular to each other. The contact fixing plane is provided with a rod A, and the rod A is provided with an insulating plate which is provided with a plurality of static contacts, wherein the number of the static contacts is the same as the number of moving contacts on a circuit breaker handcart. The lateral and longitudinal distances among the plurality of static contacts are the same as the lateral and longitudinal distances among the moving contacts on the circuit breaker handcart. The invention has the following beneficial effects that the device is low in construction cost, is flexible in operation, is convenient to move, effectively solves a problem that the cooperation between the device with a switch cabinet in the prior art needs to be adjusted continuously, enables installing planes of the moving contacts of the circuit breaker handcart to remain consistent, and eliminates the hidden troubles of partial heating and partial discharging.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker handcart calibration device and a calibration method thereof. Background technique [0002] The circuit breaker handcart needs to have high dimensional accuracy in use. If the size deviation is slight, the dynamic and static contacts will not cooperate well, the conductivity will be poor, the contact resistance will be large, and the temperature will rise. can not be used. In the production process of the circuit breaker handcart, in order to ensure the dimensional accuracy of the circuit breaker, a complex calibration device is used in the processing line, which is expensive and requires a high level of technical level for the operators and users. Since most switchgear manufacturers and substations do not have circuit breaker processing lines to use, it is difficult to calibrate the circuit breaker handcart for dimensional deviation. [0003] When th...
