中压开关设备母线搭接技术的应用

介绍了中压开关设备的母线除应满足额定电压、工作电流、温升、电压降损失等标准要求外,还应满足电流分布均匀、机械强度高、散热良好等条件。设计了各种母线的搭接结构,并对其优缺点作了分析,阐述了母线搭接应注意的问题,通过母线搭接技术的实施将有利于提高产品的质量,降低开关设备的成本。

Application of Medium-Voltage Switchgear Bus-Bar Link Technique

Introduction was made to the bus-bar of medium-voltage switchgear for in addition to meet rated voltage, working current, the standard requirements of temperature rise and voltage down losses etc., it should also meet current even distribution, high mechani-cal strength, good elimination of heat etc. Design of various kinds of bus-bar link structure was made, and analysis was made on its advantage and disadvantage, describing the problems which should be paid attention to in bus-bar linking. Via carrying out of bus-bar link technique, it will be favorable to raise the quality of product and reduce the cost of switchgear.
