| 在10kV及以下电压等级的配电网络中，真空断路器已逐步取代油断路器。高压真空断路器具有适合频繁操作、电寿命长、检修维护工作量小、防燃、防爆、运行可靠性高等优点。 Vacuum circuit breakers have gradually replaced oil circuit breakers in distribution networks with voltage levels below 10 kV. High voltage vacuum circuit breaker has many advantages, such as suitable for frequent operation, long electrical life, low maintenance workload, flame-proof, explosion-proof, high reliability and so on. 由于生产厂家不同,有部分真空断路器性能很差,特别是断路器的特性方面,存在的问题较多。断路器的部分缺陷容易造成重大事故，或造成事故越级导致大面积停电。 Due to different manufacturers, some vacuum circuit breakers have poor performance, especially in the characteristics of circuit breakers, there are many problems. Some defects of circuit breakers are easy to cause serious accidents, or lead to large-scale blackouts. |
