Problems solved by technology

[0002] Now in the working process of substation preventive test and whole group transmission test, it is often necessary to simulate the primary current on the equipment. The current test equipment needs to be installed and tested by the operator to complete, but due to the requirements of voltage level and insulation distance , These tests generally belong to high-altitude operations, which will bring a lot of work intensity to the testers, and the safety hazards are also relatively large, which brings a lot of inconvenience to the preventive testing work of substations

Embodiment Construction

[0007] The embodiment is described in detail in conjunction with the accompanying drawings, a large current simulation test device, which includes an insulating rod 6, an adjusting nut 5, a threaded rod 8 is provided at the end of the insulating rod, a pressure plate 4 is provided on the top of the threaded rod, and the threaded rod The top assembly is equipped with an adjusting nut, and is fixedly connected with the adjusting nut to be provided with a high-current wire clip 2, and is provided with a busbar hook 1 on the top of the high-current wire clip. When the present invention is in use, first clamp the large current generating wire 7 with a large current wire clamp, then adjust the position of the adjusting bolt, and then hang the busbar hook on the busbar 3, and then the test can be carried out. The operator operates the insulating rod on the ground The operation can be completed, and the bus bar hook can be selected from an aluminum material with better electrical condu...

Abstract

The invention discloses a large-current simulation test device which is reasonable in structure and convenient to use. According to the technical scheme, the large-current simulation test device comprises an insulating rod and an adjustment nut, a threaded rod is arranged at the end of the insulating rod, a pressing plate is arranged at the top of the threaded rod, the adjustment nut is assembled on the threaded rod, a large-current wire clamp is fixedly connected with the adjustment nut, and a bus hook is arranged at the upper portion of the large-current wire clamp. The large-current simulation test device is reasonable in structure and good in use effect, preventative testing of a transformer substation can be completed without climbing operation, the construction efficiency is greatly improved, and potential safety hazards are reduced.

Description

Technical field: [0001] The invention relates to an auxiliary tool for electric power construction and testing, in particular to a large current simulation test device. Background technique: [0002] Now in the working process of substation preventive test and whole group transmission test, it is often necessary to simulate the primary current on the equipment. The current test equipment needs to be installed and tested by the operator to complete, but due to the requirements of voltage level and insulation distance , These tests generally belong to high-altitude operations, which brings a lot of work intensity to the testers, and the safety hazards are also relatively large, which brings a lot of inconvenience to the preventive testing work of substations. Invention content: [0003] The purpose of the invention is to design a large current simulation test device with reasonable structure and convenient use [0004] The technical solution of the present invention...
