异型母线在低压开关柜中的应用

Application of Non-conventional Type Busbar in Low-voltage Switchgear Cabinet

简要介绍了国内外低压成套开关柜母线系统和EN13605异型母线标准。结合GZT低压成套开关柜的MXY异型母线,论述了异型母线的动热稳定性;根据GZT低压成套开关柜CCC认证试验数据,通过分析对比,表明4 000A／5 000A异型水平母线系统比矩型水平母线系统节约铜材30％。

Brief introduction was made to low-voltage switchgear assemblies busbar system both at home and abroad and EN13605 non-conventional type busbar standard. Combined with GZT low-voltage switchgear assemblies MXY non-conventional type busbar, its dynamic stability was discussed. Based on GZT low-voltage switchgear assemblies CCC accreditation data, via analysis and comparison, it shows that 4 000 A/5 000 A non-conventional type level busbar system saves 30 % copper material than rectangular level busbar system.
