Three-way module

Abstract

The invention discloses a three-way module. The three-way module comprises a shell, a first insulator connected with a lightning arrester, a second insulator connected with a GIS equipment bus or an isolating switch, a plurality of first communication assemblies, a conductive seat connected with a voltage transformer and a second communication assembly. The shell is provided with an operation opening; the second insulator and the first insulator are respectively arranged on two opposite surfaces of the shell; the first communication assemblies are arranged in the shell and connected between the first insulator and the second insulator, and comprise plum blossom contacts arranged on the first insulator, first conducting rods arranged on the second insulator, and detachable conductors of which the two ends are detachably connected with the plum blossom contacts and the first conducting rods respectively; the conductive seat is arranged on the shell; and the second communication assemblyis arranged in the shell, is connected between one first conducting rod and the conductive seat, and comprises a bus coupler conductor arranged on the first conducting rod and a second conducting rodof which the two ends are respectively connected with the bus coupler conductor and the conductive seat. According to the invention, the on-site installation efficiency can be improved, and the insulation risk of the lightning arrester and the voltage transformer is eliminated.

Description

technical field [0001] The invention relates to the field of high-voltage switchgear, in particular to a three-way module. Background technique [0002] In the existing technology, considering the user's technical level and the limitations of special tools and equipment, when installing the high-voltage switchgear, the manufacturer usually completes the docking installation of the lightning arrester and voltage transformer with the high-voltage switchgear, and then transports it to the site as a whole. However, when the power frequency withstand voltage test is carried out on site, because the withstand voltage frequency and peak value are not consistent with the GIS equipment body, it is necessary to isolate the arrester from the voltage transformer, and reassemble after the test, resulting in low installation efficiency and cumbersome operation on site. Need to invest in specialized staff and installation tools and equipment. Contents of the invention [0003] The purpo...
