| 摘 要： | 由于被试设备的多样性,火电厂中压电气设备进行交流耐压试验时,电容电流都不尽相同,试验电压的高低不等,需要多台不同型号、容量的试验变压器。同时由于变压器容量的不同,适用范围也比较狭窄,设备的利用率相对较低。为此提出利用工频不完全谐振的方法,完成火电厂中压电气设备的交流耐压试验。

| Abstract: | For the inequality of capacitance current and testing voltage of various equipments,the test of AC withstanding voltage of power plant＇s electrical equipment requires four or more testing transformers with different models and capacity volumes. The different capacity volumes of transformers lead to limited scope of applications and low efficiency of devices. A method of incomplete resonance at the power-frequency is put forward to complete the test of AC withstanding voltage of power plant＇s medium-voltage electrical equipment. |
