在设计机务段、车辆段车库、客车技术作业站整备场、站修所、工务修配厂等,经常将电焊机固定在一定的位置,因此,在库内或室外的作业场所要求在适当的距离设置便于手把线连接的端子。一般设计的二次线路中的一条导线,库内的则沿墙或沿柱子上架设,室外的则沿杆架设。为便于电焊作业,在适当的距离须设引下线一处,并设电焊接线端子;另一条回线则利用钢轨作为导体。两根钢轨的端头须焊上跨接线,两条钢轨之间,钢轨与电焊机之间,采用扁钢或元钢进行焊接,联成一个整体。与手把线的联接,在以往设计中方法上有采用电流较大的双极闸刀开关(200安),将两极并联起来当作单极用;亦有采用大型插销连座的。采用上述设备。须使用单根截面积较大的铝芯绝缘线,线径较粗,对施工安装及接线均
In the design of the locomotive depot, depot garage, bus technology station preparation field, station repair, repair shop, etc., often welding fixed in a certain location, therefore, in the library or outdoor workplaces require a suitable distance Set the terminal for easy hand wire connection. A general design of the secondary line in a wire, the library along the wall or along the erection of the erection, outdoor erection along the pole. In order to facilitate welding operations, at a suitable distance to be set down a line, and set the welding terminal; the other line is the use of rail as a conductor. The ends of the two rails shall be welded to the jumper wire. Between the two rails and between the rails and the welding machine, flat steel or elemental steel shall be used for welding to form a whole. With the handle line connection, in the past the design method has a larger current bipolar knife switch (200A), the two poles in parallel as a single pole; also have a large plug with a seat. Using the above equipment. Must use a single larger cross-sectional area of aluminum insulated wire, thicker wire diameter, the construction of the installation and wiring are
