Device and method for measuring contact depth of moving and static contacts of switchgear

Abstract

The invention discloses a device for measuring the contact depth of switch cabinet movable and static contacts. The device comprises a fixed ring and further comprises a locking device, a reference adjusting device and a reading device. The invention further discloses a method for measuring the contact depth of the switch cabinet movable and static contacts. The method includes the steps that firstly, the device for measuring the contact depth of the switch cabinet movable and static contacts is taken out and installed; secondly, a reading is measured, wherein the first step includes the substeps that the reference adjusting device is installed in advance, the fixed ring is installed and fixed, the reference adjusting device is detached, and the reading device is installed; the second step includes the substeps that the movable contact is pushed to a critical contact position, and the contact depth of the movable and static contacts is read. The device for measuring the contact depth of the switch cabinet movable and static contacts has the advantage of being convenient to install, and the method for measuring the contact depth of the switch cabinet movable and static contacts has the advantages that the contact depth of the movable and static contacts is read in real time and operation is quick and stable.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a device and method for measuring the contact depth of moving and static contacts of a switch cabinet. Background technique [0002] Because the high-voltage switchgear is fully enclosed and the space in the contact box is small, even if the handcart is shaken to the working position when the bus is powered off, the operation and maintenance personnel still cannot accurately measure the contact condition of the plum blossom contacts, and can only rely on Open the partial visual inspection of the busbar warehouse; in addition, in many cases, the maintenance work of the handcart circuit breaker on the busbar without power failure is carried out, and the static contacts on the busbar side are charged, and the operation and maintenance personnel cannot confirm the actual contact situation; so usually they can only rely on Hand crank to the fixed indicator point at the working...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned device has the following problems: 1. It is necessary to install a fixing piece on the static contact. Since the static contact is located deep inside the switch cabinet, it is inconvenient to operate, and it is difficult to ensure that the fixing piece is flush with the front end of the static contact. 2. Since the contact position of the moving contact is not at the stop end, and the front end of the static contact is provided with a chamfer of the section section, the critical contact position between the moving contact and the static contact is the contact point The contact position with the chamfered end, so the fixed part cannot be installed at the front end of the static contact, and the sliding part can not be installed at the end of the moving contact
