摘要
母线的选用是成套开关设备设计须认真考虑的问题,对于低压成套开关设备来说,由于其基本结构、使用条件、具体型号参数的不同以及母线的规格、尺寸、安装方式、材质等的不同都影响到低压成套开关设备的试验数据,试验的温升、短路耐受、防护等级等试验都会受到影响。合理的母线安装是确保低压成套开关设备的安全性能、使用寿命的前提。
The selection of Busbar is a serious problem to be considered in the design of complete switchgear,the test data of low-voltage switchgear are affected by the differences of its basic structure,operating conditions,specific type and parameters,as well as the specifications,sizes,installation methods and materials of the busbars,the temperature rise,short-circuit tolerance,protection level and other tests will be affected.Reasonable busbar installation is the premise to ensure the safety performance and service life of low-voltage switchgear.
