(Summary description)The closed busway installation technology has higher requirements. The general horizontal installation is much more difficult than the vertical installation, mainly because of the heavy weight. Therefore, the horizontal installation requires high quality of the embedded parts on the building structure, the strength of the support structure, Installation accuracy requirements are also high. In order to ensure the quality of the installation, it is best to use the theodolite to find the uniform height on each embedded part at the construction site, and mark it with a marker. This can effectively reduce the horizontal installation error. The closed busway and the low-voltage terminal of the oil-immersed power transformer shall be connected by soft connection. That is to say, using a wire braided flexible wire or other type of flexible conductor between the two

Information

The closed busway installation technology has higher requirements. The general horizontal installation is much more difficult than the vertical installation, mainly because of the heavy weight. Therefore, the horizontal installation requires high quality of the embedded parts on the building structure, the strength of the support structure, Installation accuracy requirements are also high. In order to ensure the quality of the installation, it is best to use the theodolite to find the uniform height on each embedded part at the construction site, and mark it with a marker. This can effectively reduce the horizontal installation error. The closed busway and the low-voltage terminal of the oil-immersed power transformer shall be connected by soft connection. That is to say, a wire braided flexible wire or other type of flexible conductor transition connection is used between the two. This connection is not necessary for connection to a dry transformer. If the closed busway is rigidly connected with the low-voltage terminal of the oil-immersed power transformer, the low-voltage terminal will not be able to withstand the expansion stress of the closed busway, causing the casing to leak oil, thus affecting the normal operation of the transformer. When the closed busway is horizontally installed, the plug-in box and the enclosed busway are integrated, and the installation position is high, which is not convenient for future operation and maintenance. Therefore, it is preferable not to install a switch in the plug-in box, only to connect the conductor and the cable, and to introduce the power source into the wall-mounted power box installed nearby. The closed busway has a high cost. It is not reasonable to use closed busway for some load-constrained or separate power supply equipment. In addition, the closed busway installation technology is relatively high, and the installation cost is naturally high. Therefore, before deciding whether to choose a closed busway, it is important to make a comprehensive economic and technical comparison of the closed busway scheme with other schemes. Closed busway is basically a maintenance-free line, but if it is in a humid or corrosive gas environment, such as coastal areas, textile companies, etc., a comprehensive anti-corrosion coating and maintenance is required every one or two years.
