Dianci bileiqi, 2020 在特高压换流站中,中性母线避雷器组以及转换开关避雷器组中并联柱数多,导致这两处位置的避雷器组故障频发,继而很大概率导致直流系统闭锁。目前的避雷器用脱离器以及压力释放装置等保护措施无法为解决避雷器故障会导致直流系统闭锁的问题,因此提出一种多柱并联避雷器组熔断式故障退出措施。在避雷器单元筒内部每一柱氧化锌电阻上串联一个特性匹配的熔断器,一旦某一柱的电阻片吸收能量过多出现击穿、电流集中灌入时,该柱熔断器在保护系统发出闭锁指令前快速熔断并隔离该故障柱,保证避雷器组剩余部分仍可正常运行 ...

Gaoya dianqi, 2009 笔者主要以贵广二回直流工程为例,首先介绍了大地回线和金属回线的转换原理及其过程,其次介绍了在调试和运行过程中导致大地回线和金属回线转换不成功的运行实例,然后分析了直流保护逻辑存在的缺陷所导致的金属回线向大地回线转换时MRTB、MRS频繁分合的情况。笔者就这一情况提出了相应的保护逻辑修改方法,并发现保护逻辑经修改后,金属回线/大地回线转换正常,在系统调试和实际运行中不再出现MRTB、MRS频繁分合的情况。

Dianci bileiqi, 2020 在换流站金属转换开关（MRTB）转换操作的过程中,并联的避雷器组在开关动作后需要快速吸收大量能量。但是多柱并联结构的避雷器普遍存在氧化锌电阻片能量吸收不均的问题,在长期运行多次动作后以及环境因素影响下,避雷器组局部伏安特性降低会使较小阻抗的单柱氧化锌承受更大能量,吸收能量超出其热容量时会发生热崩溃导致击穿故障。近几年多次发生由于避雷器组损坏而导致金属转换开关转换失败的事故。为了解决避雷器故障的问题,本文以±660 kV宁东换流站为例,通过理论计算以及仿真分析提出金属转换开关避雷器参数要求 ...
