煤矿安全监控系统浪涌防护技术研究

摘要

The conventional surge protection technology was introduced.Based on theoretical research and standard test of electromagnetic compatibility surge protection technology in coal mine safety monitoring system,it was indicated that the conventional surge protection technology had certain unsuitability to coal mine products.Two major conflicts were focused on,which were between the conventional common-mode surge protection technology and insulation withstand voltage requirements of coal mine equipments as well as the conventional system-level surge protection design and intrinsic safety requirements of coal mine electrical equipments.The two conflicts were analyzed in principle and corresponding solutions were given finally.%介绍了常规浪涌防护技术,基于煤矿安全监控系统电磁兼容浪涌防护技术的理论研究和标准试验测试,指出常规浪涌防护技术对煤矿产品存在一定的不适用性,重点就常规浪涌防护设计与煤矿设备绝缘耐压要求及常规系统级浪涌防护设计与煤矿电气设备本质安全要求两大冲突问题进行了研究,并结合实际进行了原理性分析,最后给出了冲突问题解决方案.
