摘要
电容式电压互感器(CVT)具有性能优良、成本低廉、设计及制造技术已非常成熟等优点。因此现阶段在百万伏级交流特高压输电线路中采用CVT是最佳选择。文章介绍了特高压CVT的原理及结构、应重点研究的内容,如机械强度和抗震能力、无线电干扰水平、电场分布等,给出了主要参数与性能指标。西安西电电力电容器有限责任公司所研制的1000kVCVT样机已于2006年12月完成了所有的型式试验(包括抗震试验),并通过了技术鉴定。
Capacitive voltage trnsformer （CVT） has good performance with lower cost and mature design and manufacturing technology, which is best option now for adopting CUT in 1000 kV UHV power transmission line. The principle and structure of UHV CUT, and the contents of key research for UHV CVT were introduced, such as mechanical strength and anti-seismic ability, radio influence level and electric field distribution etc., and the major parameters and performance index were given, The prototype of 1000 kV CVT made by Xi＇an Xidian Electric Power Capacitor Co. had been completed all type tests including anti - seismic test in December 2006, and passed through technical appraisement.
