摘要
通过对低压漏电保护装置的系统研究和试验 ,指出了存在的问题 ,设计并制作了一种新型低压漏电保护装置 ,在实践中证明其安全、可靠 ,效果良好。
By systematic study and test for the leakage protection of low-voltage,common problems are pointed out in the paper.A novel leakageprotection of low-voltage is designed and made.It has been fully proved in practice that this device is safe,reliable and good results.
