Abstract

The utility model discloses an electrical performance tester for a multi-core cable used for spacecraft thermal tests. The electrical performance tester is used for measuring interline conductivity and interline insulativity of the cable, and comprises a cable adapter unit, a signal leading-in and connecting unit, a central control unit, a relay switch control unit, a test voltage generating unit, a test circuit unit, a data processing unit, a data storage unit and a human-computer interaction unit. The electrical performance tester is small in size, light in weight and easy to carry, does not need to replace measuring terminals by manual operation in the test process, can automatically complete the switching of measuring channels by the system, achieves the automatic and rapid measurement of electrical performance tests of the ground test cable, can automatically generate test reports, and improve the degree of automation and accuracy of cable tests.

Description

technical field [0001] The invention relates to the technical field of cable electrical performance measurement, in particular, the invention relates to an electrical performance testing device for cables used for spacecraft heat tests. Background technique [0002] During the design, assembly and various tests of the spacecraft, a large number of cables for ground testing are used. Before using the cables, it is usually necessary to test the continuity between the cables and the insulation between the cables to ensure the integrity of each cable. Good conduction and insulation between lines. [0003] Usually, the insulation test between the two wires of the cable is carried out with an insulation tester, that is, the positive and negative terminals of the instrument are respectively connected to the corresponding pins of the two wires under test, and then the insulation tester is started for testing. Read the insulation resistance between the wires to judge the insulation ...
