Debugging device of route and opening range size of circuit breaker

Abstract

The invention relates to a debugging device of a route and an opening range size of a circuit breaker. The device comprises a supporting rod, a rotary fan plate, a U-shaped route plate, a clamping plate and an adjusting screw rod, wherein the rotary fan plate is provided with a thread hole and the lower end of the adjusting screw rod is rotatably arranged in the thread hole of the rotary fan plate; the adjusting screw rod is rotatably arranged at the lower end part of the route plate in a penetrating manner and is positioned and matched with the U-shaped route plate through a positioning structure; the positioning structure comprises a screw sleeve, a clamping groove arranged on the adjusting screw rod and a clamping ring clamped in the clamping groove; when the upper end of the adjusting screw rod is contacted with the clamping plate, the size from the center of the connecting part of the clamping plate to the upper end face of the screw sleeve is the pre-set size of a switching-on position; the size from the center to the upper end part of the U-shaped route plate is the pre-set size of a switching-off position; and the lower end part of the supporting rod is provided with a fixing structure for fixing the supporting rod on a cross beam of the circuit breaker. According to the debugging device disclosed by the invention, the route and the opening range of the circuit breaker are debugged to be standard, so that the error caused by manual discontinuous measurement is reduced and the debugging device is very convenient and rapid.

Description

technical field [0001] The invention relates to a debugging device for a circuit breaker, in particular to a debugging device for locating the opening and closing positions of a circuit breaker product. Background technique [0002] At present, in the process of assembly test and debugging of high-voltage circuit breakers, the measurement and debugging of important parameters such as the stroke and opening distance of the circuit breaker are all measured with relatively high-precision measuring tools. The standardized use of measuring tools in the process of measuring and debugging There is no unified requirement, and due to human factors in the measurement process, measurement errors or other errors may occur, resulting in inaccurate measurements and debugging dimensions, affecting product testing, and seriously causing product damage and injury during the testing process Wait.
