厂用中压开关柜厂用中压开关柜medium voltage switch-gear cubicles for station auxiliariesChongyong zhongyo kolguongUI厂用中压开关柜(medium voltage switehgeareubieles for station auxiliaries)用于中压厂用系统,接受和分配电能给电厂辅助设备,并为这些辅助设备提供控制、测量、保护和信号等的成套配电装置。厂用配电装置的特点是操作频繁,因此要求其安全可靠、便于检修和适合于频繁操作。厂用中压开关柜均布里在户内,可分为手车式和固定式两种。手车式开关柜的手车可以互换,检修时可用备用手车恢复供电,缩短检修停电时间;断路器可以随手车拉出柜外,检修方便;手车式还有落地式和中置式(参见彩图擂页第35页75图),后者柜体布置更合理,检修更方便。由于这些优点,在电厂,手车式开关柜较固定式开关柜得到优先采用。中压开关柜内可装设不同型式和规格的断路器。断路器一般有少油、真空和SF。等型式。少油断路器系老产品,不能防火、防爆、不适合频繁操作,运行维护费用大,可靠性低,现被真空断路器取代。美国过去采用磁吹断路器,现也被真空断路器取代而淘汰.在中国,中压开关柜内也有采用SF‘断路器的,但在厂用电系统中很少采用。在70年代底80年代初,世界上一些制造商推出由中压熔断器与真空或SF‘接触器组合成的F一C手车式开关柜,以熔断器和热过负荷继电器作为保护电器,接触器作为操作电器,其价格低,适用于频繁操作,运行维护工作量少,占用开关柜的空间较小,可减少配电室的面积,首先应用于工业企业供电系统,后又在厂用电系统中采用。F一C手车式柜的可靠性主要决定于熔断器的工作可靠性和稳定性,与被保护设备的容童和性质有关.近年来,中国也已生产相应的F一C手车式柜,并已在厂用电系统中广泛应用。厂用中压开关柜除应满足规定的运翰、工作环境和短路条件下的机械和电气性能外,开关柜内的绝缘构件应具有阻燃和低吸潮性能,主母线、分支母线和连接线宜采用绝缘母线;还应具有标准规定的机械和电气的闭锁装置,以确保人身和设备的安全。配里真空断路器的开关柜内应按真空断路器断开时可能出现的过电压值配里相应的过电压抑制装置,一般为氧化锌进雷器,以使负载端和母线系统免受超过绝缘水平的过电压。开关柜内电气设备的载流能力会因柜体封闭而受到影响,因此应通过试验验证其载流能力或提出降容系数。
