Development of Capacitor Voltage Transformer with High-quality Transient Response Characteristics

主要阐述了一种用于超高压直流输电交流侧的具有高品质暂态响应特性的电容式电压互感器(简称CVT)的研制过程和其具有的各种性能。该CVT是针对超高压直流输电换流站成套设备研制项目而研制的交流电容式电压互感器,主要通过对影响CVT暂态响应特性的因素进行分析,配合合理的设计,通过试验验证,达到具有高品质暂态响应特性。

This paper describes mainly the development process and its various performance of a type of capacitor voltage transformer with high-quality transient response characteristics for the AC side of EHVDC transmission （ referred to as CVT）. This CVT is an AC capacitor voltage transformers developed for the development project of the complete set installation of EHVDC converter station. A high-quality transient response characteristic is achieved through mainly analysis of factors affecting CVT＇ s transient response characteristics with reasonable design and validation by way of test.
