Abstract

The present application provides a plug-in type current intrinsically safe terminal, the terminal is arranged between the relay protection device and the transformer equipment, including: a base connector, an isolation plug and a test plug; the base connector is provided with a base terminal The base terminal block is integrated on the base connector. One end of the base terminal block is continuously connected to the relay protection device through wires, and the other end is connected to the transformer equipment. At the same time, the base terminal block is movable with the test plug or isolation plug. connected. The plug-in current intrinsically safe terminal provided by this application can control the normal connection or short connection of the connection line of the terminal block of the base through the insertion or removal of the isolation plug or the test plug, and can realize the connection between the primary equipment and the secondary equipment, and the secondary equipment. The high-efficiency on-site rapid test, plug and play, avoids the influence of on-site personnel and equipment conditions on the cable connection quality, and has the characteristics of safe, convenient and efficient use.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a plug-in current intrinsically safe terminal. Background technique [0002] In recent years, various potential hidden troubles often appear in the secondary circuit of the power system whether it is a new investment or an operating plant and station, causing accidents caused by relay protection and other devices to malfunction or refuse to operate. The secondary circuit of the station current is used for relay protection and other related work. [0003] When carrying out work related to relay protection in substations, there is a risk of accidental tripping of the protection device. At this time, it is necessary to take corresponding secondary safety measures. It is necessary to remove the relevant secondary circuits of the current voltage and the trip circuit. Or during the recovery process, there may be risks of accidental touch, insufficient recovery, or reco...
