振荡型雷电冲击电压下油纸绝缘气隙模型局部放电特性
|
摘要
研究了基于IEC60060-3标准的振荡型雷电冲击电压下油纸绝缘气隙模型的局部放电特性,建立了1台符合IEC60060-3标准的振荡型雷电冲击电压发生器,它能够产生各种类型的振荡型雷电冲击电压波形,正负极性可调。利用高频电流传感器(HFCT)测量振荡型雷电冲击电压下的局部放电,结果表明,振荡型雷电冲击电压的极性和振荡频率对局部放电特性的影响很小,且其幅值与局部放电个数呈正比例关系。
The paper investigates the partial discharge characteristics of a cylindrical void in oil-immersed insulation under the oscillating lightning impulse voltage based on IEC60060-3 standard,and sets up an oscillating lightning impulse voltage generator,which satisfies the requirements of the IEC60060-3 standard,to produce the oscillating lightning impulse voltages.Moreover the generator can produce a variety of oscillating frequencies and positive and negative oscillating lightning impulse voltage.A high frequency current transformer(HFCT) is used to measure the partial discharge.The experimental results suggest that the polarity and oscillating frequency of the oscillating lightning impulse voltage has a small effect on the partial discharge characteristics,and the number of the partial discharge pulses is proportional to the amplitude of the oscillating lightning impulse voltage.
