串补站用旁路隔离开关研究设计

Design of Bypass Disconnector for Series Compensation Station

随着电力系统的不断发展和扩大,需要采用串联补偿装置来提高系统输送能力和系统的稳定运行水平。笔者通过分析串补站的原理,提出了串补站中旁路隔离开关的设计思路,旁路隔离开关是保证串补装置的投入和切出的重要设备,对旁路隔离开关设计时不仅需要考虑电流负荷及绝缘性能,还需要考虑开合一定的母线转换电流。最后,提出了在进行旁路隔离开关设计时应按不同工况设计考虑不同的设计方案。

With the development of power system, series compensation equipment has to be employed to improvetransmission ability and stable operation of the power system. The author analyzes the principle of seriescompensation station, and presents a design idea of bypass disconnector. Bypass disconnector is an importantdevice for switching on/off the series compensation equipment, so its design needs to consider the current stressand the dielectric performance, as well as the ability of switching bus-transfer current. The design of bypassdisconnector ought to consider particular working condition.
