| Abstract: | Based on describing the principle of insulation monitoring protection in6KV flameproof switchgear,the cause of producing stray current in ground networks is analyzed in detail and the effect of stray current upon the insulation monitoring system is also discussed in this paper.According to the characteristic of stray current,a novel anti-interference method based on orthogonal transformation is proposed and a new insulation monitoring system is developed.The test results show that the insulation monitoring system developed by the method is stable and reliable and is of great applied value in mining industry. |
