| 摘 要： | 1 000 kV交流系统GIS用罐式避雷器的电位分布影响特高压输变电系统的可靠运行,为此针对其结构制定了电位分布的测量方案,并对因测量时改变结构而引起的一些影响因素进行了分析。通过改变伸缩连接杆的长度以改变均压环的罩入深度,调节均压环与均压环、均压环与均压罩之间的距离等多种方式调节均压装置的结构,并采用光纤-电流法进行测量,对数据进行分析比较得到了最优结构的参数,结果表明,电位分布不均匀系数经优化后完全满足规定值(15%)。

| Abstract: | Potential distribution of MOA for 1 000 kV AC GIS imposes effect on the stability of the 1000 kV Ultra-High-Voltage(UHV) power system,Hence a method to measure and adjust the potential distribution is presented considering the structure of the MOA,and some influence factors caused by MOA structure change in measurement are analyzed.The optimum structure is obtained by adjusting the voltage grading device through multiple ways,measuring the potential distribution with optical fiber current method,and analyzing all parameters of the voltage grading device.The result shows that the uneven coefficient of potential distribution is less than 15% after optimization,meeting the standard satisfactorily. |
