摘　　要：复合电器(H-GIS)是不含母线的GIS。与GIS相比具有下列优点:(1)H-GIS内绝缘部位少,环氧树脂浇注绝缘件比GIS减少约一半,壳体数量及壳体内表面积比GIS大大减少,因此极大地减小了“面积效应”产生的不良影响。(2)H-GIS的密封环节比GIS少,密封系统的泄漏几率小,维护更简单。(3)综合造价低,约为GIS设备的34％。(4)由于H-GIS设备母线敞开,扩建、检修和更换都很方便。H - GIS is a kind of GIS without bus and it has the following advantages comparing to GIS: (1) Less internal insulation position, number of epoxy resin poured insulating pieces is a half of GIS and number of casing; and internal surface area in them greatly less than that of GIS, which has greatly reduced the unfavorable influence produced by the 'area effect' . (2) Seal links of H-GIS are less than GIS and probability of seal system leakage is less with simple maintenance. (3) Low general cost, about 34% of GIS equipment. (4) The bus of H- GIS device is open, which is convenience for expansion, maintenance and replacement.
