摘要
分析了AC型剩余电流保护器剩余电流特性试验的电流产生方法,依此提出了研制大电流试验设备的思路,使之具有较小的成本和体积并严格满足标准要求。
The method of producing residual current for characteristic test of AC type residual current protector was analyzed,and based on this,the solution of making test instruments with large current capacity was given.The instrument cost less and had smaller volume while meeting the test standards strictly.
