Description

technical field [0001] The invention relates to the field of cable insulation detection, in particular to a cable insulation detection device. Background technique [0002] In the ground test of various types of aviation products, a large number of test adapter cables are often used. Such cables need to be tested for insulation performance during production and use. At present, there are two common detection methods, that is, the qualitative detection method of the hand-operated megohmmeter and the quantitative detection method of the digital megohmmeter, but there are the following deficiencies: 1. The detection efficiency is low: the qualitative detection method of the hand-operated megohmmeter Three test positions are required, and the utilization rate of human resources is low; the megohmmeter used in the quantitative detection method of digital megohmmeter needs to be converted by AD, and the test results show that the reaction speed is slow. 2. There are many factors ...

At present, there are two common detection methods, that is, the qualitative detection method of the hand-operated megohmmeter and the quantitative detection method of the digital megohmmeter, but there are the following deficiencies: 1. The detection efficiency is low: the qualitative detection method of the hand-operated megohmmeter Three testing positions are required, and the utilization rate of human resources is low; the megohmmeter used in the quantitative detection method of the digital megohmmeter needs to be converted by AD, and the test results show that the response speed is slow

2. There are many factors involving human instability, which affect the test results: hand-operated megohmmeters rely on manual shaking of the handle, which makes it difficult to ensure constant speed, resulting in unstable test voltage, and difficulty in identifying the deflection of the megohmmeter pointer; digital megohmmeters The meter adopts quantitative detection technology, but the result interpretation is time-consuming, and it is easy to cause visual fatigue when there are many test core wires, which will affect the test results
