| 摘 要： | 阐述了特高压长南Ⅰ线、南荆Ⅰ线断路器重合闸投退后，长治站、南阳站线路故障联动串补重投功能不会自动投退，人工投退该功能需要轮退2套串补控制保护，不仅要操作硬压板76次，还要操作软压板4次，操作流程繁琐，增大了误操作的可能性，且串补控制保护退出也存在一定的安全风险。对特高压串补装置的结构和线路故障联动串补重投功能进行了介绍，分析了特高压线路故障联动串补重投功能投退方法。

| Abstract: | For UHV Chang-nan line Ⅰ and Nan-jing line I,when circuit breaker recloses,series compensation will not automatically input or withdraw,and manual switching needs two systems of series compensation control and protection,which demands to operate the hard plate for 76 times and soft plate for 4 times. The complicated operating process increases the possibility of misoperation and it is risky to withdraw the control protection system. What is more,the structure of UHV series compensation device is introduced and the switching method for input or withdrawal is analysed. |
