摘要
提出一种新型绝缘漏流测试系统,它将既有1700型继电器绝缘测试选择电路变更为板载继电器选择电路,并增加低压快速测试功能;在继承既有绝缘测试电路优点的基础上,具有体积小、集成度高、功能多、扩展方便等特点,提升了监测技术水平。
A new-type insulation leakage current test system is introduced, which can change the existing 1700 relay insulation test selection circuit to on-board relay selection and incorporates lowvoltage fast test function. On the basis of inheriting the advantages of the existing insulation test circuit, the test system features small size, high level of integration, multi-functions and easy expansion and improve the level of monitoring technology.
