摘要
设计一种40.5 k V SF6压气式负荷开关柜,采用独特的压气式负荷开关,改良的开断断口在灭弧时降低了SF6化学反应产生的废弃物,具有充气压力低、开断容量大、使用寿命长、可实现"三遥"等配电自动化功能,且可依据不同的使用要求灵活进行扩张和组合。该产品符合GB 11022和IEC 60376标准,通过了型式试验,并已应用于实际工程中,取得了良好的经济效益。
This paper designed a kind of 40. 5 k V SF6pressure-operated load switchgear,which uses a unique compressed-air load switch,less waste by optimizing the break. It has low gas pressure,large breaking capacity,long serving life and 'three remote 'control available,what 's more,flexible expansion and combination in order to satisfy customers need. The product meets with the standard of both GB 11022 and IEC 60376,and it has passed type test and acquired good economic benefits in real project.
