摘要
随着电子技术的发展,高灵敏度、快速动作型漏电保护装置获得了极大的发展。但是,由于煤矿井下工作环境恶劣,电气设备长时间运行容易绝缘老化、受潮和受损,失去绝缘作用,因而经常会出现漏电故障。本文在深入研究矿用高压组合开关照明保护箱及其操作经验的基础上简化了该保护箱,解决了其外壳带电的问题。既便于井下工人的操作,又方便检修及故障点的排查。
As a result of the poor coal mine working environment, the electrical equipment is easy to be aging, moisture, damage and loss of insulating effect with long-running. So leakage faults occur frequently. The illumination protecting box is simplified through the deep research of the leakage protector and the operation experience, and the problem of the protecting box outer covering charged is solved. It is simple to operate for mine shaft workers and convenience to investigate for the fault point.
