| 摘 要： | 在微机综合保护器过热保护元件校验中,电流回路分别输入三相平衡电流和单相电流时,得到相对应的电流时间特性曲线,通过对这些不同的特性曲线进行分析判断,能够正确地判断过热保护元件是否正常工作.文中探讨了在实际工作中,利用单相电流测试法对三相电子式过热保护元件进行测试、判断其能否正常工作的方法.

| Abstract: | During the verification of overheat protection elements of microcomputer protector,the corresponding current-time characteristics are obtained when current circuits separately input three-phase equilibrium current and single-phase current.By analytical judge of these different characteristics,we can judge whether the overheat protection elements function properly.This paper discussed the actual application of single-phase current testing method for testing of three phase electronic overheat protection elements and the method for judging whether they function properly. |
