其次对于高压负荷开关及低压馈电开关部分存在的问题，则通过应用新型开关设备来解决。
Secondly, for some problems in high voltage switches and low voltage feed switches, new switching equipment is used to resolve the problem.
提高了接通和分断能力，动热稳定性好，适于频繁操作，是FB - 6高压负荷开关的更新换代产品。
Enhance the connecting and breaking capability, and fine moving and thermal stability, suitable for frequent operation, it is the new generation instead of FB-6 HV load switch.
高压、超高压输电线路的开关为分相开关，当对侧开关单相偷跳后，在线路负荷比较重、同时重合闸动作时间比较长的情况下可能引发系统振荡。
HV and EHV transmission lines are equipped with split-phase breaker. If a longer reclosing time is setting in a heavy load line, the system may swing after the trip without fault of remote breaker.
