摘　　要：针对目前检查电气设备绝缘状况最常用的数字式兆欧表依次测量三相绝缘电阻时,存在频繁倒换试验接线的问题,效率低下又耗时。研究设计了一种数字多功能绝缘电阻测试仪,通过其内部接线切换装置实现不倒换外部试验接线,即可安全、可靠测量被试设备三相绝缘电阻,提高了测试的工作效率。Digital megohmmeter is commonly used to check the insulation condition of electrical equipment.When it is used to measure the three-phase insulation resistances successively,the test wiring need to be switched frequently,which is inefficient and time consuming.A digital multi-functional insulation resistance tester is designed,in which an internal wiring switching device is adopted.Thus,the three-phase insulation resistances of the tested equipment can be measured safely and reliably without external wiring switching,which improves the work efficiency of the test.
