Example Embodiment

[0018] The embodiment of the detection tool for opening and closing the arc extinguishing chamber of the circuit breaker in the present invention: figure 1 with figure 2 As shown, the detection tool is a ZF27 / LW55-800 circuit breaker 6 extinguishing chamber slow opening and slow closing tool, which is composed of a support base 1 and a transmission mechanism. The transmission mechanism is a screw transmission mechanism of a sliding screw nut pair type, including a sliding nut 2 assembled in the support base 1 and a screw 3 adapted to the sliding nut 2 to rotate around an axis extending up and down. The inner wall of the sliding nut 2 is threadedly connected to the outer circumference of the lead screw 3. The lower section of the sliding nut 2 is protruded with an annular limit shoulder on the outer circumference, and the upper section of the sliding nut 2 is fixedly connected with a force applying hand wheel above the support base 1. 4. The upper section of the lead screw is ...

Abstract

The invention discloses an arc extinguishing chamber switching-closing detection tool for a circuit breaker. According to the tool, a supporting seat is mounted on a transmission box of the circuit breaker, and a lead screw and a nut are mounted on the supporting seat to form a spiral transmission mechanism, so that power is inputted. When switching-closing actions of a movable contact and a fixed contact in an arc extinguishing chamber of the circuit breaker are detected, the nut is manually screwed, so that the lead screw drives a power input end of the movable contact to act through a traction structure, arc extinguishing chamber switching-closing actions of the circuit breaker are manually controlled, the nut in the spiral transmission mechanism accurately rotates, the rotating speed of the nut is easily controlled, the switching-closing processes of the movable contact and the fixed contact can be timely observed, and the switching-closing positions are easily measured by the aid of accurate spiral transmission, so that the switching-closing actions of the arc extinguishing chamber are more conveniently detected and more accurately and conveniently observed by the detection tool.

Description

technical field [0001] The invention relates to the field of assembly detection of a circuit breaker, in particular to an opening and closing detection tool for an arc extinguishing chamber of a circuit breaker. Background technique [0002] At present, with the continuous development of high-voltage circuit breaker technology, more and more high-voltage power transmission fields have higher and higher reliability requirements for the opening and closing actions of circuit breakers. During the assembly process of the arc chamber, the opening and closing actions of the dynamic and static contacts must be stable and reliable, especially for the ZF27 / LW55-800kV circuit breaker. High, and after the assembly of the arc extinguishing chamber is completed, the resistance and other data of the arc extinguishing chamber need to be tested. When there is a problem with the detection of the centering accuracy of the dynamic and static contacts and the resistance measurement of the circ...
