Abstract

The invention relates to a transformer test wiring auxiliary tool which comprises an n-shaped wire clamp and an insulating rod used for supporting the wire clamp. The wire clamp is provided with two connecting plates, and each connecting plate is provided with a movable wiring board with a recessed circular pit in the middle. The inner side end of the connecting plate is connected with a contact piece; a spring with upper and lower ends exerting force is mounted on an opening side connecting plate of the wire clamp; the insulating rod is connected with a detachable supporting rod, the structure is simple, the wiring mode can be changed according to different test requirements in use, wiring personnel do not need to climb a sleeve, and the risk of falling from a high place is reduced; a bucket arm vehicle does not need to be used, the risks of mechanical collision and mistaken touching of electrified parts in the operation process are avoided, and wiring work can be completed by one person.

Description

technical field [0001] The invention belongs to the field technical field of substation inspection and maintenance, and relates to an auxiliary tool used for test wiring of a 220kV transformer in a substation, in particular to an auxiliary tool for test wiring of a transformer. Background technique [0002] The transformer is the core electrical equipment of the substation. Its main function is to transform the voltage, that is, to change the voltage on the power supply side to the required voltage level. Its main components are: iron core, winding, insulating oil, lead wires of each phase and bushing, etc. For transformers of 110kV and above, an electrical routine test is required every 3 years to check the mechanical characteristics and insulation performance of the equipment. [0003] In the electrical test project of the transformer, the tests of the winding and the bushing DC resistance, insulation resistance, dielectric loss, and AC withstand voltage need to connect t...
