Abstract

The invention relates to an auxiliary positioning tool and a use method thereof. The auxiliary positioning tool is used for mounting an energy storage motor of a breaker and comprises a base and an abutting part arranged on the base and smoothly connected with the base; the abutting part and the base are arranged concentrically; the outer diameter of the abutting part is reduced from the side close to the base to the side far away from the base; and the outer diameter of the base is larger than or equal to the maximum outer diameter of the abutting part. By the aid of the auxiliary positioningtool, the time for replacement or mounting of the energy storage motor is greatly shortened, so that the work efficiency of maintenance personnel is improved, the safety risks are reduced, and the stability of an electric power system is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a positioning auxiliary tool and a using method thereof. Background technique [0002] The circuit breaker occupies a large proportion in the power system. The circuit breaker usually uses a hydraulic spring mechanism to store energy. The energy storage motor is arranged in the mechanism box, and the space is small. When the energy storage motor fails, the circuit breaker will not be able to open and close normally, causing the circuit breaker to refuse to operate, seriously affecting the stability of the power system. When designing the circuit breaker mechanism box, considering the vibration process caused by the opening and closing of the circuit breaker, the arrangement of the energy storage motor is rigorous. Not only is it fixed with bolts, but it is fastened with a card slot at the position of the transmission shaft of the energy storage motor to prevent it from go...
