山东电缆桥架之母线桥刷漆的效果：绝缘、防腐、散热和“相”的标识。带型母线母线和关闭式插接母线槽其实即是一个关闭一个不关闭。关闭式母线简称是母线槽，也即是说母线槽是关闭式母线的马甲，关闭式母线和母线槽指的都是同一种东西。 关闭式母线是由金属板(钢板或铝板)为维护外壳、导电排、绝缘资料及有关附件构成的母线体系。

　　The effect of brushing on the bridge of the Shandong cable bridge: insulation, corrosion protection, heat dissipation and phase marking. The belt type bus bar and the closed plug-in busbar are in fact a closed one and not closed. The closed type bus is referred to as the bus slot, that is to say, the bus bar is the waistcoat of the closed type bus, and the closing type bus and the bus slot refer to the same thing. The closed bus is a bus system composed of metal plates (steel plates or aluminum panels) for the maintenance of housings, conductive rows, insulation materials, and related accessories.

　　它可制成每隔一段距离设有插接分线盒的插接型关闭母线，也可制成中心不带分线盒的馈电型关闭式母线。是将主母线选用金属外壳关闭的母线。

　　The utility model can be made into a plug type closing bus with an inserting and distributing box at intervals, and can also be used as a feeding type closing type bus without a distributing box in the center. Is the bus with bus closed metal shell.

　　母线桥又称桥式接线，用跨接断路器BCD把两条电源引进线与两台变压器联系起来的主接线。

　　The bus bridge is also called bridge connection. The main connection between the two power lines and the two transformers is connected by the jumper breaker BCD.

　　较分段单母线接线简化，削减了断路器的数量。依据跨接桥断路器的方位不一样，分为内接线桥和外接线桥。其间内接线桥适用于线路较长，负荷曲线对比平稳的变电方位;外接线桥则适用于线路较短，负荷曲线改动较大的变电方位。

　　The single bus connection is simplified and the number of circuit breakers is reduced. According to the different directions of the bridge breaker, it is divided into the inner line bridge and the outer connection bridge. In the meantime, the connection bridge is suitable for the substation with long line and stable load curve, and the outer connection bridge is suitable for the substation with shorter line and larger load curve.

　　关闭式母线可分为密集型绝缘母线和空气型绝缘母线，适用于额外作业电压660V、额外作业电流250～2500A.频率50Hz的三相四线制或三相五线制供配电线路，它具有计划紧凑、绝缘强度高、传输电流大、交流功用好、电气功用安稳、易于设备修补、寿数时间长等一系列特征。

　　The closed bus can be divided into intensive insulated bus and air insulation bus, suitable for extra work extra work voltage of 660V, current of 250 ~ 2500A. frequency 50Hz three-phase four wire or three-phase five wire power supply line, it has plans for compact, high dielectric strength, large current, AC transmission function, good electrical function safe and easy to repair equipment, life long time a series of features.
