High-altitude wiring device for electrical test of transformer and combined electric appliance

Abstract

The invention discloses a high-altitude wiring device for an electrical test of a transformer and a combined electric appliance, which belongs to the technical field of electrical tests and comprises a wire clamp, a cross rod and an insulating rod. The wire clamp comprises a wire clamp shell, a first pressing tongue, a second pressing tongue and an insulated wire; the first pressing tongue and the second pressing tongue form a clamping opening; the first pressing tongue is provided with a copper sheet, and the insulated wire is connected with the copper sheet. The cross rod is connected with the wire clamp shell; the insulating rod and the cross rod are connected and installed in an angle-adjustable manner. The first pressing tongue and the second pressing tongue are used for hooking the tested equipment, so that the connection reliability can be realized; the first insulating pressing tongue is used for meeting the test requirement of the resistance measurement test double-arm bridge; the wire clamp, the cross rod and the plurality of insulating rods are connected in sequence, and the application to different electrical tests and different working conditions can be realized by adjusting the angle between the insulating rods and the cross rod and increasing the length of the insulating rods; high-altitude wiring requirements can be met, working efficiency is improved, and potential safety hazards are reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical testing, in particular to a high-altitude wiring device used for electrical testing of transformers and combined electrical appliances. Background technique [0002] In order to ensure the normal operation of the power system, it is necessary to conduct electrical tests on transformers and combined electrical appliances to check whether the performance of the equipment is good. The test items include: transformer winding DC resistance test, transformer ratio test, transformer winding deformation test, dielectric loss factor test of transformer and its bushing, transformer insulation resistance test, combined electrical circuit resistance test, etc. [0003] The above test items need to connect the test wire at the bushing terminal board. When the transformer bushing is assembled, it is inclined outward, and the heat sink is directly under the wiring board. The vertical distance between the wir...

Problems solved by technology

There are many problems in using insulated bucket trucks for wiring, such as a large number of operators (a total of four people are required, two bucket truck wiring operators, one person to monitor, and one person to cooperate with the wiring on the transformer), difficult implementation, and high safety risks. Long working hours and high safety hazards
