摘要
针对旧国标中现有充电桩没有明确规定绝缘自检功能而存在安全隐患的问题,对比平衡电桥法、不平衡电桥法、直流法3种绝缘检测方法的优缺点,从检测原理、功能、注意事项等方面对绝缘检测装置进行分析,并通过实例验证该装置增加了充电桩充电的安全可靠性。
For the problem of potential safety hazard caused by the lack of specific regulations of old Chinese Standard charging piles＇ isolation self-checking function,we compare the merits and drawbacks of the method of bridge balancing,the method of bridge imbalance and the method of direct current isolation cheking.We analyse the isolation cheking device in checking principle,function and matters needing attention.In addition,we validate the charging safety and reliability of device by examples.
