摘要
研制了一种基于标准电容器的集中式电容分压器,该分压器的高低压臂电容电极采用同种金属极板材料并处于压缩SF6气体绝缘介质中,可以保证分压器高低压臂电容温度系数、电压系数等特性参数的一致性,进而保证电容分压器分压比的稳定性;采用理论计算及仿真分析相结合的方式确定了标准电容器各部分的尺寸。针对绝缘外筒表面上存在电压分布不均匀的情况,在分压器内部加设多层均压电极后改善了绝缘套管上的电场分布情况。经实际测试,标准电容分压器高压臂电容量及分压比实测值与理论计算值十分接近,其高压臂电容量电压系数为1.01×10-5。
This paper developed a centralized standard capacitance divider based on standard capacitor. The highvoltage arm and the low voltage arm using the same metal plate material and be placed in the compressed SF6 to en-sure the consistency of the divider. By calculating and simulation analysis,the combination of the various parts of thestandard capacitor is determined. According to the uneven voltage distribution on the surface of the insulating outercylinder,we use several multilayer uniform electrodes to the internal voltage divider. By actual test,the measuredvalue of the high voltage arm capacity and the divider ratio of the standard capacitive voltage divider is very close tothe the oretical calculation value,and the voltage coefficient of e high voltage arm is 1.01×10-5.
