Movable test wire fixing hanging point structure

Abstract

The invention discloses a movable test wire fixing hanging point structure, and belongs to the technical field of relay overhaul, the movable test wire fixing hanging point structure comprises a fixing cover, a magnet block, a connecting piece and a fixing ring, the magnet block is arranged in the fixing cover, the right side surface of the magnet block is fixedly connected with a fixing plate, a limiting mechanism is arranged in the fixing plate, and the limiting mechanism is clamped in the fixing cover; and two positioning mechanisms which are symmetrical left and right are arranged in the fixing ring. According to the invention, the magnet block is arranged and adsorbed on the screen cabinet door, the fixing ring can be fixed at the moment, the test wire can be hung on the fixing ring at the moment, the magnet block does not fall off, the test wire can be effectively fixed, when the pull block is controlled to move downwards, the slide rod can be pulled to move downwards, and the top end of the slide rod can pull the other end of the pull rope. The moving track of the pull rope can be changed under the action of the guide wheel, the limiting rods can be driven to move downwards when the connecting block is pulled up and down, the two limiting rods do not block the notch of the fixing ring any more, and at the moment, people can conveniently take out the buckled test wire.

Description

technical field [0001] The invention belongs to the technical field of relay maintenance, and in particular relates to a fixed hanging point structure of a mobile test line. Background technique [0002] When relay protection professionals are performing protection, measurement, safety and other equipment function verification, they need to connect multiple current, voltage, signal and other test wires from the test instrument to the equipment test terminals, sometimes as many as 20 test wires. Wire. There is no special hanging point for the test line behind the relay instrument room of the high-voltage switchgear cabinet and the protective screen cabinet. Usually, the test line is often hung on the screen cabinet door and on the cable line of the terminal block. The test line is very long and has a certain amount. The weight of the wire clip on the test terminal will cause a pulling force, so that the wire clip can easily fall off. The tester often wastes a lot of time on ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is: in order to solve the problem that the test line is often hung on the screen cabinet door and the terminal row cable line during the usual test. The test line is very long and has a certain weight. Pulling force is generated, so that the wire clip is easy to fall off, and the test personnel often waste a lot of time on the wiring. If the wire clip falls off during the test of applying voltage and current, it will pose a threat to the personal safety of the test instrument or the staff, and the proposed moving Type test line fixed hanging point structure
