Problems solved by technology

At present, when conducting the mechanical performance test of the test product, there is no resistance measurement interface on the entire device. It is necessary to wait for the test product to be disassembled after the mechanical performance test is completed to complete the resistance measurement. This will cause the resistance measurement point to be different each time. This will affect the accuracy of the measurement results

Abstract

The invention discloses a gas insulated transmission line contact life test device. The device comprises a first cylinder and a second cylinder for simulating two adjacent working cylinders of a gas insulated transmission line, a first conductive part is fixedly assembled in the first cylinder, a second conductive part is slidably assembled in the second cylinder, the first conductive part and the second conductive part match a contact base through a sliding contact in an inserted mode, the device comprises a driving mechanism and a resistance measuring assembly, and the end, away from the first cylinder, of the second cylinder is provided with the driving mechanism for driving the second conductive part to do axial reciprocating motion; and the resistance measuring assembly for realizing fixed-point resistance measurement is arranged on the first cylinder. The resistance measuring assembly is additionally arranged on the first cylinder and used for achieving fixed-point measurement of the resistance, it is ensured that measuring points are the same each time, resistance measuring errors caused by human factors are avoided, the insulation performance of a test object can be tested under the condition that the test object is not disassembled after a mechanical performance test is completed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rigid gas-insulated transmission lines, in particular to a device for testing the life of contacts of gas-insulated transmission lines. Background technique [0002] Gas insulated transmission line is a new type of transmission line that adopts gas insulation, and the shell and conductor are coaxially arranged. It has a series of advantages such as large transmission capacity, small footprint, high reliability, maintenance-free, long life, and environmental friendliness. This makes it the first choice to replace overhead lines or cable lines in special environments. During the operation of the gas-insulated transmission line, due to the thermal expansion and contraction, the sliding contact and the sliding three-pillar in the gas-insulated transmission line pipeline and the sliding fitting parts of the conductive rod that slide relative to the conductive rod will inevitably move. The movement of the slid...
