| 摘 要： | 介绍了500 kV串补系统中广泛应用的火花间隙系统结构及导通原理。针对GTD强电磁干扰的工作条件重新设计其相关电路,阐述了其工作原理及特点;介绍了密封间隙的结构及导通原理,通过对密封间隙和整个火花间隙进行触发试验,结果表明,新设计的GTD装置能够可靠地将密封间隙强制击穿导通,进而使整个火花间隙系统导通。实际人工接地短路试验结果表明整个火花间隙能够可靠地强制导通。 |
| 关 键 词： | 串联补偿 火花间隙 间隙触发装置 密封间隙 MOV保护 |

| Abstract: | The configuration and breakdown principle of the spark gap system,which is widely used in 500 kV series compensation system,are introduced.Considering the strong electromagnetic interference,the circuit of the gap triggering device(GTD)is redesigned,and its principle and characteristic are discussed.The configuration and spark breakdown principle of the trigatron are described.Triggering tests of trigatron and spark gap indicate that the improved GTD can stably break down the trigatron,and subsequently break down the complete spark gap.Artificial single-phase grounding test demonstrates that the complete spark gap can be stably broken down. |
| Keywords: | series compensation spark gap GTD trigatron MOV protection |
