Problems solved by technology

Due to the inconsistency of the size and parameters of the equipment of various manufacturers, each station needs the corresponding manufacturer to temporarily provide modules such as test casings. Due to the different structures and large sizes of the pressure-resistant interfaces and casings, the space required for the test is large.
For the increasing number of indoor products and areas with

Abstract

The invention discloses a three-phase to single-phase test device. The structure is connected by adopting a three-phase to single-phase structure for the first time. The three-phase to single-phase test device comprises a change-over switch module used for connecting a casing and a bus. The three-phase to single-phase test device further comprises a casing assembly used for performing a cable or bus insulation test. The three-phase to single-phase test device has the beneficial technical effects that (1) the solution is compact in structure, and the occupation space is greatly reduced comparedwith a traditional device; (2) test methods for different sizes of products of different manufacturers are unified through the test device, the universality is high, and the field test capability ofcovering various products by one device can be achieved; (3) the test device is simple in structure, mature in field construction process and short in construction period; and (4) the test device provides a convenient insulation test interface, and an insulation test is performed on GIS buses and cables very conveniently.

Description

technical field [0001] The present invention relates to a conversion device, more specifically, to a test device for three-phase to single-phase conversion, suitable for SF 6 During the on-site insulation test of gas-insulated fully enclosed combined electrical equipment (GIS), the conversion of phase commutation tests for different phase sequences is carried out. Background technique [0002] At present, high-voltage fully enclosed combined electrical equipment (GIS) products are more and more widely used in power grids of various voltage levels. After the equipment is installed, there is an increasing demand for on-site insulation tests on GIS products. The project requirements for the insulation test of GIS products such as shells are becoming increasingly stringent. At present, the way to conduct insulation tests on GIS products on site is to conduct corresponding insulation tests after docking temporary bushings provided by various manufacturers with products, and three...
