Auxiliary joint device of switch mechanical characteristic tester

Abstract

The invention provides an auxiliary joint device of a switch mechanical characteristic tester. The auxiliary joint device comprises a shell, a fixed arm, connecting wires, a wire plugging bench, a backboard wire jack, an inner wire and loop pin holes. The wire plugging bench is arranged on one surface of a backboard of the shell and is used for mounting the backboard wire jack; the loop pin holesare formed in one surface opposite to the backboard of the shell and used to match a to-be-tested plug; one end of the inner wire is connected with the loop pin holes, and the other end of the inner wire is connected with the backboard wire jack; one end of each connecting wire is connected with the backboard wire jack, and the other end of the connecting wire is connected with the switch mechanical characteristic tester. The loop pin holes of the auxiliary joint device match the to-be-tested plug and make sound contact with the to-be-tested plug in a plug-in way, short circuit is avoided, andthe surfaces of loop guide pins do not deform or loosen. Besides, according to different tested plugs, the connection position of the inner wire and the loop pin hole can be simply changed, so that the detection of various switch plugs can be satisfied.

Description

technical field [0001] The invention relates to the technical field of electrical testing; more specifically, it relates to an auxiliary joint device for a switch mechanical characteristic tester. Background technique [0002] The high-voltage switch dynamic characteristic tester, namely the high-voltage switch dynamic characteristic tester, is a special instrument developed to meet the needs of on-site testing of the high-voltage switch action characteristics. [0003] High-voltage switch is a general term for equipment with a voltage exceeding 1kV to connect or disconnect circuits, and is a very important power transmission and distribution equipment. It is safe and reliable, and is of great significance to the safe and effective operation of the entire power system. In order to ensure the safety and reliability of the high-voltage switch action, the mechanical characteristics of the switch must be strictly tested during the production, installation and commissioning proc...

AI Technical Summary

Problems solved by technology

[0004] When performing a mechanical characteristic test on a 10kV KYN / XGN switch, the clip is usually used to directly clamp the corresponding circuit guide pin to connect the high-voltage switch to the mechanical characteristic tester, but there are several defects in this connection method: 1. , when the clip is clamped, it is easy to short-circuit with other circuits, or poor contact occurs during the test, which will affect the results; 2. Using the clip to clamp the guide pin is easy to cause deformation of the guide pin, which may cause equipment failure; 3. Every time After the opening and closing operation, manual energy storage is required; 4. The existing switch aviation plug is fixed by four screws on the back, which is not easy to disassemble and replace the plug-in wire

[0005] In the actual testing process, the workload and difficulty of the maintenance personnel are usually increased due to the above defects, so it is necessary to improve the above problems in order to reduce the work difficulty and workload of the maintenance personnel
