Description

电动汽车涉水试验用测试绝缘电阻电压的测量接线装置Measuring wiring device for testing insulation resistance voltage for electric vehicle wading test

技术领域technical field

本发明属于电动汽车技术领域,具体涉及一种电动汽车涉水试验测试绝缘电阻电压测量接线装置。The invention belongs to the technical field of electric vehicles, and in particular relates to a wiring device for measuring insulation resistance and voltage of an electric vehicle wading test.

背景技术Background technique

根据涉水试验规范,涉水试验共计3个工况,在每个工况试验前30分钟内及试验后30分钟内和试验后静止24小时都需对整车绝缘电阻进行测量,共计9次测量。According to the water wading test specification, the water wading test has a total of 3 working conditions. The insulation resistance of the whole vehicle needs to be measured within 30 minutes before the test of each working condition, within 30 minutes after the test, and 24 hours after the test, for a total of 9 times. Measurement.

通常,测试绝缘电阻电压时,需要拆开高压配电盒上盖,上盖四周共有24颗螺栓紧固,不但拆解重复工作较多,且重复拆卸后极易造成螺栓帽滑牙或力矩过大后螺纹滑丝,导致上盖无法拆卸,影响试验进程。同时,涉水试验后,机舱内存有大量的水迹,在裸漏的高压电下进行测试极其危险,且由于打开高压配电盒上盖后,高压互锁开关会断开导致整车无法上高压电,需用轧带手动强行关闭互锁开关,存在漏电的风险。Usually, when testing the insulation resistance voltage, it is necessary to disassemble the upper cover of the high-voltage distribution box. There are 24 bolts around the upper cover to fasten them. Not only does the dismantling repeat work, but it is easy to cause the bolt caps to slip or excessive torque after repeated disassembly. The large rear thread slide wire makes the upper cover unable to be disassembled and affects the test process. At the same time, after the water wading test, there are a lot of water traces in the engine room. It is extremely dangerous to test under the high-voltage leakage. Moreover, after opening the upper cover of the high-voltage distribution box, the high-voltage interlock switch will be disconnected, so that the whole vehicle cannot be used. When high-voltage power is applied, the interlock switch needs to be manually and forcibly closed with the strip, which has the risk of electric leakage.

综上所述,如何解决试验时的便利性及安全性成为亟待解决的问题,基于此,急需研发一种电动汽车涉水试验用测试绝缘电阻电压的测量接线装置。To sum up, how to solve the problem of convenience and safety during the test has become an urgent problem to be solved. Based on this, it is urgent to develop a measurement wiring device for testing the insulation resistance voltage for electric vehicle wading test.
