适应复杂工况的可攀越式继电保护测试平台

Climbing Type Relay Protection Testing Platform for Complex Working Conditions

针对当前变电站在检修过程中由于测试仪难以搬运、取电困难、误操作等而导致供电可靠性降低的问题,介绍了一种适应复杂工况的可攀越式继电保护多功能测试平台。该测试平台由履带牵引模块、逆变电路模块、电压检测模块、区域告警隔离模块等构成,具有帮助各电压等级变电站中检测人员搬运测试仪时攀越楼梯、跨越障碍,通过平台自备电源向测试仪供电,检测时自定义区域隔离防误入等功能。经南京某220 kV变电站现场测试表明,该平台的使用增强了变电站检修的安全性,增加了变电站运行维护的效率,提高了供电可靠性。

In the view of current repairing process in transformer substation, this paper introduces a kind of relay protection multifunctional testing platform to solve the problem of supplying reliability decrease, which is caused by the difficulties such as carrying tester, supplying power and wrong operation etc. The testing platform is made up of crawler base module, inverter circuit module, voltage electrical measuring module, regional alarm isolation module etc., which can help testing personnel to climb stairs and cross obstacle, and supply power to testing equipment from self-contained power source and define insulation zone to avoid accidently coming to the zone etc. The results of the field testing in Nanjing 220 kV substation show the use of this platform could enhance the security of the substation maintenance, increase the efficiency of the substation operation maintenance, and improve power supply reliability.
