Insulation fault diagnosis method for cable system

Abstract

The invention belongs to a field of insulation fault diagnosis methods and specifically relates to an insulation fault diagnosis method for a cable system. The invention solves problems of long insulation fault detection time and high fault rate existing in cable system testing for a long term and provides the effective and practical method for insulation fault diagnosis of large scale cable systems. Production quality of the cable system is verified fully and the method provided by the invention has great application and promotion value. The method includes obtaining a resistance value RS through testing; testing a first pair of core points and obtaining a result about whether insulation of the first pair of core points is qualified or not; switching to the next pair of core points until insulation fault diagnosis of all the core points of the cable system is implemented and finishing the testing.

Description

technical field [0001] The technology belongs to the field of insulation fault diagnosis methods, and in particular relates to a cable network insulation fault diagnosis method. Background technique [0002] Weapons, launch vehicles and other models use large-scale cable nets, and the cable nets must be tested for insulation, withstand voltage, and conduction resistance before leaving the factory. The traditional test method is to use a shaker to test the insulation, relying on testers to manually diagnose cable network insulation faults. During the test, the personnel are prone to fatigue, resulting in repeated tests, missed tests, and failed tests. The current effective solution The method is to use the cable network tester to complete the insulation test of the cable network. This instrument automatically diagnoses the insulation faults of the cable core points in turn without manual intervention, which reduces labor costs, but it is time-consuming for multi-channel conti...

[0002] Weapons, launch vehicles and other models use large-scale cable nets, and the cable nets must be tested for insulation, withstand voltage, and conduction resistance before leaving the factory. The traditional test method is to use a shaker to test the insulation, relying on testers to manually diagnose cable network insulation faults. During the test, the personnel are prone to fatigue, resulting in repeated tests, missed tests, and failed tests. The current effective solution The method is to use the cable network tester to complete the insulation test of the cable network. This instrument automatically diagnoses the insulation faults of the cable core points in turn without manual intervention, which reduces labor costs, but it is time-consuming for multi-channel continuous insulation tests. Longer, if the instrument diagnostic method is not perfect, it will increase the probability of misjudgment

There are hidden dangers in the shooting range test. In order to ensure the correctness and applicability of the cable network insulation test, it is urgent to study the insulation fault diagnosis method to meet the requirements of fast, safe, accurate and comprehensive detection of the cable network and fully verify the production quality of the cable network.
