摘要
介绍了一起综采工作面馈电开关漏电保护不兼容故障的处理,从馈电开关附加电源极性、直流电压等级、保护器及馈电设置等方面分析了故障的原因,并对馈电开关生产厂家提出几点建议。
The processing of infeed switch leakage protection not compatible is introduced.The problem is andyzed from different aspects,such as the additional power supply polarity switch,DC voltage,protector and infeed settings.Besides,there will be some suggestions on the feed switch manufacturers to be put forward.
