摘要
在高压输变电系统中,保证电压互感器安全稳定运行非常重要。通过对TYD3-110/3^(1/2)系列电容式电压互感器(CVT)接地故障的分析、研究发现,该型电容式电压互感器自身存在的设计缺陷是故障发生的主要原因。同时恶劣的运行环境,安装检修质量的不到位也给故障的发生提供了必备的条件。
In the high voltage power transmission system, it is very important to ensure the safe and stable operation of the voltage transformer. Through the analysis and study of the grounding fault of TYD3-110√3 series of capacitive voltage transformers(CVT), it is found out that the connatural design deficiencies are the main reasons of faults. Meanwhile the adverse operation environment, substandard quality of the installation and maintenance provide the necessary condition for the occurrence of the fault.
