Development of a MV level peaking capacitor integrated capacitor voltage divider

  • 摘要: 峰化电容器由于结构紧凑一般采用间接测量其承受的电压,而峰化电容电压的直接测量一直是难以解决的问题。为了解决该问题,以峰化电容器为基础,研制了一种新型结构的电阻补偿式自积分型峰化电容一体化电容分压器。其次,根据分压器的新型结构分析了峰化电容一体化电容分压器的理论分压比,给出了理论分压比计算公式,分析了影响低频响应的因素并进行了电路仿真验证。同时,开展了方波标定实验,得到了两个探头的分压比及响应时间,且探头响应时间均小于6.2 ns。此外,为了得到更准确的分压比并验证正常工作状态下该一体化电容分压器分压比的稳定性,进行了高压在线标定实验,得到了1#探头分压比为11071,2#探头分压比为15148。且在更高电压等级下,该电容分压器探头的测量相对误差较小,分压比稳定性良好。
