Problems solved by technology

This method will produce multiple connectors in the middle of the test line, which need to be insulated, otherwise it will easily cause a short circuit in the secondary circuit of the voltage transformer, posing a safety hazard; at the same time, due to the long wiring, it is easy to make mistakes and consumes Time will bring a lot of inconvenience to on-site operations

Embodiment Construction

[0010] Below in conjunction with accompanying drawing for further explanation:

[0011] Such as figure 1 As shown, the present invention consists of two wires and a socket connection. One of the two wires is a live wire 1, one end of which is connected to the terminal of the live wire socket of the socket 3, and the other end is provided with a pin 4; the other of the two wires is a neutral wire 2, and one end thereof is connected to the socket The terminals of the neutral jack are connected to each other, and the other end is provided with pin 5. Also be provided with safety fuse 6 on live line.

[0012] The socket of the present invention is a standard power socket. In order to facilitate the identification during operation, the outer sheath and pins of the live wire are red, and the outer sheath and pins of the neutral wire are black.

[0013] Such as figure 2 As shown, when in use, the plug 8 of the power supply spool 7 is inserted into the jack of the socket of the ...

Abstract

The invention relates to a test wire special for phase testing of an intelligent substation. The test wire special for the phase testing of the intelligent substation is formed by connecting two lead lines and a socket, wherein a firing line in the lead lines is connected with a wiring terminal of a firing line jack in the socket, a null line in the lead lines is connected with a wiring terminal of a null line jack in the socket, and both the firing line and the null line are provided with contact pins. The test wire special for the phase testing of the intelligent substation is connected with a power spool of a common tool in power construction, does not need field connection in a working site, and not only can avoid potential safety hazards brought by a test wire connector, but also can improve work efficiency of the phase testing.

Description

technical field [0001] The invention relates to a test and test device for power supply equipment, in particular to a special test line for phase test of an intelligent substation. Background technique [0002] When testing phases of power transmission in smart substations, since the merging unit of the voltage transformer is often far away from the merging unit of the equipment under test, it is necessary to use multiple sets of conventional test lines in series to connect the test lines from the voltage transformer to the unit under test. equipment, and then perform phase measurement. This method will produce multiple connectors in the middle of the test line, which need to be insulated, otherwise it will easily cause a short circuit in the secondary circuit of the voltage transformer, posing a safety hazard; at the same time, due to the long wiring, it is easy to make mistakes and consumes Time will bring a lot of inconvenience to the field work.
