Problems solved by technology

[0004] The deficiencies of this application are: 1. The metal parts of the connecting piece and the shorting piece are exposed, and the electrical distance is small. When working with the same power supply and different power supply cores, it is easy to cause accidental contact, discharge, etc., resulting in insufficient protection. Correct action; 2. The connecting piece and the shorting piece are fixed by multiple screws, and it is easy to have different tightening degrees of the fixing screws, resulting in poor short-circuiting of individual points and affecting the output of the secondary voltage (missing item); 3. Short-circuiting The chip is pure metal, short circuit operation is not safe
[0005] In order to improve the short-circuit efficiency of the secondary equipment voltage test connection terminal and reduce the occurrence of secondary circuit disconnection or virtual connection caused by the traditional short-circuit method, a convenient and reliable secondary equipment test connection terminal short circuit is designed. It is necessary to connect the structure

Abstract

The invention discloses a novel short-circuit structure of test connection terminals of secondary equipment. The structure comprises bar-shaped short-circuit pins in certain thickness and a terminal row capable of accommodating the short-circuit pins, insulation sleeves are arranged on the short-circuit pins respectively, the two sides of each short-circuit pin are provided with guiding grooves respectively, and the guiding grooves are in parallel with the length direction of the short-circuit pin. The short-circuit structure has the advantages that a plug-in type short-circuit manner is usednewly, and the short-circuit efficiency is improved; the short-circuit pins have a stronger damping effect after being plugged into the terminal row, during use, the short-circuit pins are pressed into the terminal row, it is ensured that the pins are plugged in place, and a secondary loop is prevented from break or false connection; and the tail portions of the short-circuit pins are provided with the insulation sleeves additionally, and the safety of short-circuit operation is ensured.

Description

technical field [0001] The invention relates to the technical field of tool devices for electric power engineering, in particular to a short-circuit structure for secondary equipment test connection terminals. Background technique [0002] The secondary equipment test connection terminals are widely used behind the secondary compartment of the switchgear and the protective screen cabinet. They are used as connectors to supply various secondary currents and voltages to various protective devices, or to supply currents and voltages output by various protective devices. The voltage is transferred to the terminal block, and then output to other interval protection devices with the secondary cable. Some test terminals, such as current and voltage loops, need to be placed with shorting strips, which can be opened or removed when in use, and no shorting is used; some signals share the positive power supply, and the configuration of power lines can be reduced by using shorting strip...
