Limit test method and system for insulation resistance performance of slip ring

Abstract

The invention provides a limit test method and system for the insulation resistance performance of a slip ring, and the method comprises the steps: loading different environment conditions to a slip ring product, carrying out the performance test of the insulation resistance, and recording the insulation resistance values under different environment conditions, the insulation resistance values measured under different environment conditions are drawn into a curve graph of the relation between the environment conditions and the insulation resistance, and the limit value of the insulation resistance under the corresponding environment conditions is obtained. The performance of the insulation resistor of the slip ring can be systematically studied through test acquisition and comparison and drawing of a related chart, accurate data support is provided for product design, and an important judgment basis is provided for later product use, test, fault judgment and the like. According to the invention, high-reliability and large-batch product design and rapid product delivery are realized, and the reliability of product application performance is improved.

Description

technical field [0001] The invention relates to the technical field of insulation resistance performance, in particular to a limit test method and system for slip ring insulation resistance performance. Background technique [0002] Insulation resistance is an important electrical property of the slip ring. Once the slip ring fails, it will not work normally, which will affect the normal operation of the entire system. At the same time, the proportion of failures caused by insulation resistance failure in slip ring faults is also relatively high, so it is particularly important to understand the performance limit working conditions of the insulation resistance of slip ring products. [0003] The current slip ring design mostly adopts redundant design, and the insulation resistance value between the slip ring transmission channels is designed according to the theory. On the one hand, excessive redundancy will cause waste of materials and dimensions. On the other hand, redunda...

[0003] The current slip ring design mostly adopts redundant design, and the insulation resistance value between the slip ring transmission channels is designed according to the theory. On the one hand, excessive redundancy will cause waste of materials and dimensions. On the other hand, redundancy is relative. , in different environments or in certain extreme environments, the insulation resistance value of the slip ring may reach a critical value, causing the rotation transmission performance to fail
