Abstract

The invention belongs to the technical field of multi-core cable test and specially relates to a multi-core cable test auxiliary device. In order to solve the problems of low test accuracy and low test efficiency of a conventional test method in testing a multi-core cable, the invention discloses the multi-core cable test auxiliary device. The auxiliary device is an insulator structure and comprises an area to be tested and a test area, which are mutually independent. The area to be tested is internally provided with a conductive medium; and the test area is provided with a conductive plate. Short circuit operation of a plurality of core wires of a multi-core cable to be tested can be realized through the conductive medium in the area to be tested, and fixation of metal portions at the end portions of the core wires to be tested can be realized through the conductive plate. The multi-core cable test auxiliary device not only is simple in structure and convenient to operate, but also can improve multi-core cable test efficiency and test result accuracy when carrying out auxiliary test on the multi-core cable.

Description

technical field [0001] The invention belongs to the technical field of multi-core cable testing, and in particular relates to a multi-core cable testing auxiliary device and a testing method. Background technique [0002] In nuclear power plants, in order to ensure the normal operation of power supply, control, protection, nuclear measurement, lighting, etc. of the electrical equipment in the reactor containment, it is necessary for the control cables and power supply cables to pass through the electrical penetrations to realize the connection between the inner and outer parts of the containment, and these The cables are mostly multi-core cables. After the laying and installation of the multi-core cable is completed, in order to ensure the connection of each core wire in the multi-core cable and the mutual insulation between different core wires, it is necessary to test the multi-core cable, including conduction test, core pair Ground insulation test and insulation test bet...
