The invention relates to a calibration apparatus of a circuit breaker handcart. The calibration apparatus comprises a contact fixed plane and a handcart track plane, wherein the contact fixed plane is perpendicular to the handcart track plane. A rod A is arranged on the contact fixed plane; an insulating plate is arranged on the rod A; and a plurality of static contacts are arranged on the insulating plate, wherein the number of the static contacts is identical with that of moving contacts of a circuit breaker handcart and horizontal distances and longitudinal distances between the multiple static contacts are identical with the horizontal distances and longitudinal distances between moving contacts of the circuit breaker handcart. According to the invention, the calibration apparatus has the following beneficial effects: the cost is low, the operation is flexible, and the movement is convenient; a problem of continuous adjustment for operation with the switch cabinet can be effectively solved; consistency of mounting planes of the moving contacts of the circuit breaker handcart is guaranteed; and potential problems of local heating of partial discharging can be solved.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a calibration device for a handcart of a circuit breaker. Background technique [0002] The circuit breaker handcart requires high dimensional accuracy during 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; if the circuit breaker handcart cannot be pushed into the switch cabinet normally, 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 b...
