When the busbar is installed vertically, the vertical distance between the joint and the ground shall not be less than 0.7M. The vertical distance between the joint and the floor should not be less than 0.3M. The distance between the back of the busbar and the wall should not be less than 0.1M.

　　母线槽在楼层间垂直安装时，母线槽单根直线长度不应大于3.6M；单层超过3.6M的楼层，应分两节以上制作，层间应安装中间固定支架。母线槽连接点不应在穿楼板处进行，母线槽安装穿楼板孔时不应有污水、杂物进入母线内部。

　　When the busbar is installed vertically between floors, the single line length of busbar should not be greater than 3.6M. The floor with a single floor over 3.6M should be made for more than two sections, and the intermediate support should be installed between the floors. The connection point of the busbar slot should not be carried out at the floor of the floor, and there should be no sewage and sundries entering the busbar when the busbar slot is installed through the floor.

　　母线槽插接馈电孔应设在可靠及安装维修方便位置。插接箱安装后，箱底高度不应低于0.9M母线槽垂直安装时，应将弹簧支架安装于母线槽上，再将母线槽及弹簧支架固定于槽钢固定架上，锁紧支架的弹簧螺母；待安装4~5层后，由上向下逐层松开螺母，使母线槽重量自然承载于支架弹簧上。

　　The feed hole in the busbar slot should be located in the safe and reliable position of the installation and maintenance. The connection box is installed, the height should not be lower than the 0.9M busbar vertical installation, should be installed on the busbar on the spring bracket, then the busbar and spring bracket is fixed on the fixed channel frame, spring nut locking bracket; to install the 4~5 layer after layer by layer from top to bottom, loosen the nuts, the bus weight bearing on the natural groove on the spring bracket.

　　母线槽的过渡连接母线槽始端与配电柜接线端连接，应采用镀锡硬铜排过渡连接母线槽始端与变压器、发电机组等震动较大的设备连接时，应采用铜编软连接。铜母排与铝导体连接时，应采用铜铝过渡排或夹装铜铝过渡片。

　　The transitional busbar busbar connection end and switchboard terminal connection, should connect busbar end connected with transformers, generators and other equipment with larger shock transition hard copper tin, copper series should adopt flexible connection. Copper bar and aluminum conductor connection, the copper aluminum transition row or clamping piece of copper aluminum transition.

　　母线槽运行中，应不间断查看整条系统的四周是否存在渗漏、喷水、潜在的潮气源。是否存在对系统构成威胁的重物，以及对母线槽系统温升构成影响的热源。检查有无异物进入母线槽内部。

　　In the operation of the busbar slot, it should be uninterrupted to see if there is leakage, water spray and potential tidal source around the whole system. Whether there is a heavy object that poses a threat to the system, as well as the heat source that affects the temperature rise of the busbar system. Check whether there is a foreign body into the busbar slot.

　　检查母线槽系统零部件有无缺损、锈蚀现象，支架弹簧是否有合适的弹力，发现问题后立即更换。母线槽长期运行时每年定期检测一次接头温升，接头温升应按照GB7251标准不超过70K为合格（环境温度为40℃）。

　　Check whether the parts of the busbar slot system have defects and rust, whether the support spring has the appropriate elastic force, and replace it immediately after the problem is found. The joint temperature rises regularly every year when the busbar slot is run. The temperature rise of the joint should be qualified in accordance with the GB7251 standard not more than 70K (the ambient temperature is 40).
