从技术原理上分析,漏电保护器也存在可能产生拒动的技术误区。
1,当中性线产生重复接地时,会使漏电保护器产生分流拒动,而中性线重复接地点是很难找到的。
2,当电源缺相,所缺相又正好是漏电保护器的工作电源时,会产生拒动。
最后还需特别指出两点:1.当发生人体单相触电事故时(这种事故在触电事故中几率最高),即在漏电保护器负载侧接触一根相线(火线)时它能起到很好的保护作用。
如果人体对地绝缘,此时触及一根相线一根零线时,漏电保护器就不能起到保护作用。

如果输入的整形数小于K1,输出限位到LO_LIM,并返回错误代码。
版权所有。
反向定标的实现是通过定义LO_LIMHI_LIM来实现的。
反向定标后的输出值随着输入值的增大而减小。
