Abstract

The invention discloses a universal combined short-circuit device for heavy current tests. The universal combined short-circuit device for the heavy current tests comprises a grounding bar component, a plurality of phase wire copper bar components and a connecting piece, wherein the grounding bar component is connected with the phase wire copper bar components respectively through the connecting piece; the grounding bar component comprises a grounding bar clamp and a grounding wire connected with the grounding bar clamp; and one end of the connecting piece is provided with a grounding wire connection hole. The device has the characteristics of high use flexibility, small size, low weight, attractive appearance, simplicity in operation, rapidity in locking, safety, reliability and the like.

Description

technical field [0001] The invention relates to a shorting device, in particular to a universal combination shorting device for large current test. Background technique [0002] The high current test is an important test for relay protection staff to detect rheology and related secondary and tertiary circuits. During the test, it is necessary to short-circuit the ends of one or more warehouses. Switch cabinets with different voltage levels and insulation forms have different terminal conditions. At present, there are no special short-circuit tools. Grounding wires, self-made aluminum mesh cables, self-made copper bars and other tools are often used for short-circuiting. It is inconvenient and irregular to use. The security is not high. Contents of the invention [0003] The purpose of the present invention is to provide a universal combination shorting device for large current test, which has the characteristics of high flexibility, small size, light weight, exquisite app...
