An outlet pressure plate pin-type experimental clip

Abstract

The invention provides an outlet pressing plate pin type experiment clip. An outlet pressure plate pin-type experimental clip, which includes a first clip, a second clip and a transition section, the first clip and the second clip are connected through the transition section, and the first clip A pin is set between the second clip and the first clip is provided with an experiment line connection hole, and a metal wire is arranged inside the experiment line connection hole, and the metal wire passes through the interior of the transition section and connects with the Pin electrical connection. The invention makes the signal current of the test line flow to the pin through the test line connection hole and the metal wire provided on the first clip of the test clip, and firmly clamps the first and second clips on the pin-type outlet pressure plate through the tensile structure superior.

Description

technical field [0001] The invention relates to the technical field of pin connection on a press plate, and more specifically, to an outlet press plate pin-type experimental clip. Background technique [0002] To carry out the regular inspection of protection and safety automatic devices in the substation, it is necessary to test the action time of the outlet contacts of the protection and safety automatic devices. Nearly half of the outlet pressure plates of the secondary equipment in the substation are typical pin-type outlet pressure plates, but In the current work, the pins used for terminal debugging are inserted into this pin-type outlet pressure plate, and the experimental wires are connected to the pins for terminal debugging to carry out the next experimental operation. The pins used for terminal debugging are directly inserted into the outlet pin-type outlet pressure plate. The connection is not firm, and the pins of the terminal are easy to slip off. During the wo...

AI Technical Summary

Problems solved by technology

The pins used for terminal debugging are directly inserted into the outlet pin-type outlet pressure plate. The connection is not firm, and the pins of the terminal are easy to slip. In the work experiment, careless touch will lead to risks such as failure of startup and jumping out of the outlet.

Another connection method of the pin-type pressure plate is to use threaded experimental terminal pins. This connection method is reliable, but the threaded pins are originally used in the terminal row. If used in the pin-type outlet pressure plate, the pins will be damaged. The risk of the pin-type outlet pressure plate, resulting in poor contact of the pin-type outlet pressure plate, resulting in tripping and failure of the circuit
