A special sensor bracket for vs1 type circuit breaker characteristic test

Abstract

The invention discloses a special sensor support for a VS1 type breaker characteristic test. The sensor support is integrally of a combination structure. The sensor support comprises a connecting rod and a support head. The connecting rod comprises a small connecting rod head, a rod body and a big connecting rod head. The big connecting rod head is provided with an internal thread. The support head comprises a support head body, stand bars and a connecting column. The support head body is a cylinder with the surface diameter being 32 mm. The middle of one surface of the support head body is provided with the connecting column, and the middle of the other surface of the support head body is provided with a hole. The two pairs of stand bars are arranged along the periphery of the surface where the hole is located, and each pair of stand bars is symmetrical about the center point of the hole. The stand bars are provided with threaded holes, and the big connecting rod head is connected with the connecting column. Due to the fact that the sensor support is integrally of the combination structure and machining is carried out step by step, materials are saved; when the sensor support is damaged, it only needs to replace one component, and cost is saved; the sensor support has the advantages of being simple in structure, low in cost, convenient to install and long in service life.

Description

technical field [0001] The invention relates to a special sensor bracket for characteristic testing, in particular to a special sensor bracket for VS1 type circuit breaker characteristic testing. Background technique [0002] With the acceleration of the power grid construction, the scale of the power grid is expanding year by year, and the maintenance equipment of the substation maintenance team is increasing. According to relevant regulations, when the circuit breaker is handed over and overhauled, it is required to do the mechanical characteristic test of the circuit breaker. When doing VS1 type circuit breaker When testing mechanical properties, it is necessary to measure the important data of score and closing speed. VS1 (ZN63A) indoor high-voltage vacuum circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed installation unit or as a propulsion mechanism to form a handcart unit. Due to its special ...
