【摘要】：为了研究高压直流复合绝缘子表面电荷积聚现象,研制了一套新型的可用于伞裙结构绝缘子的表面电荷检测装置。装置使用改进的电容探头,通过GPRS无线通讯方式进行数据传输,并借助于LabVIEW软件进行数据处理;设计了机械控制装置来带动探头对绝缘子进行360°精确扫描。此装置可以实现复合绝缘子伞裙和护套表面的自动精确测量。测量结果表明,在阴极端第1个伞裙表面电荷积聚量相对较大,且主要为负电荷。分析表明,伞裙表面电荷来源主要是电极附近的局部放电。
[Abstract]:In order to study the surface charge accumulation of HVDC composite insulators, a new type of surface charge detection device which can be used in parachute insulators is developed. The device uses an improved capacitance probe to transmit data through GPRS wireless communication, and uses LabVIEW soft parts to process data. A mechanical control device is designed. This device can carry out the accurate scanning of the insulators by 360 degrees. This device can realize the automatic and accurate measurement of the surface of the umbrella skirt and the sheath of the composite insulators. The measurement results show that the amount of the charge accumulation on the surface of the first parachute skirts is relatively large and mainly negative. The analysis shows that the surface charge source of the parachute skirt is mainly the local area near the electrode. Discharge.
