雅万高铁150 kV牵引变电所电压电流回路整组测试工法

Assembly Test Method for Voltage and Current Circuits of 150 kV Traction Substation of Jakarta-Bandung HSR

电气化铁路牵引变电所电压与电流二次回路的检查,是电气试验检测工作的重要内容,也是保证牵引变电所正常启动的必备条件,关系到全所设备运行的安全与稳定。利用牵引变压器本体的短路阻抗特性,采用整组测试工法,在变压器的高压侧输入低电压电源,低压侧短路时,检测整个变电所的电流二次回路;低压侧开路时,检测整个变电所的电压二次回路。根据现场实际情况,并通过提前精准计算,对雅万高铁150 kV牵引变电所电压电流回路进行试验检测。结果表明,整组测试工法得到实践验证,取得了良好应用效果,为雅万高铁牵引变电所顺利受电启动提供了坚实的技术保障。

The inspection of the voltage and current secondary circuits of electrified railway traction substation is an important part of electrical test,and also a necessary condition to ensure the normal startup of traction substation,which is related to the safety and stability of equipment operation in the whole substation.According to the short-circuit impedance characteristics of traction transformer body,assembly test method is adopted to test the current secondary circuit of the whole substation when low voltage power supply is input at the high voltage side of the transformer and the low voltage side is short-circuited;when the low voltage side is open-circuited,the voltage secondary circuit of the whole substation is tested.According to the actual site conditions and through accurate calculation in advance,the voltage and current circuits of 150 kV traction substations of Jakarta-Bandung HSR are tested.The results show that the assembly test method has been verified in practice and achieved good application effects,providing a solid technical guarantee for the smooth power-on startup of traction substations of Jakarta-Bandung HSR.
