| 摘 要： | 煤矿地面电气系统的接地和接零的接线保护方式,与漏电保护装置配合,经实践验证,存在着盲区。为消除安全隐患,对地面三相和单相电气设备漏电保护进行改进,采用电压检测型漏电保护。该漏电保护技术经现场长期实践验证,实现了漏电超过安全电压立即断电的功能,既消除人身触电隐患,又避免漏电保护过于灵敏无法送电,同时还解决了设备正常运行时轻微漏电无法使用漏电保护装置的问题。

| Abstract: | The ground and neutral wiring protection ways of coal mine ground elec trical system coordinates with leakage protection device,which exist blind area by practical proving.In order to eliminate potential safety problems,the grou nd three-phase and single phase electrical equipment leakage protection are being improved,which adopts voltage detection leakage protection.This leakage protection technology realizes the function that cuts off immediately when l eakage over safety pressure by long-term practical proving.It both eliminates p ersonal electric shock hazard,but also avoids the leakage protection too sensit ive to transmit power,while the problem that device can not use when slight lea kage during normal operation is also solved. |
