Description

Technical Field

[0001] The invention relates to the technical field of high-voltage busbar bridges, and in particular to an adjustable high-voltage busbar bridge. Background Art

[0002] It is usually made of metal materials, such as steel, aluminum alloy, etc. It has high strength and good conductivity, and can withstand the weight of the high-voltage busbar and the stress generated during operation. Its shape is generally trough, tray or ladder type, etc., to adapt to different installation environments and requirements. In order to ensure the insulation and safety distance between the high-voltage busbars, partitions are usually set in the bridge to separate the busbars of different phase sequences. The cover is used to cover the top of the bridge to prevent foreign objects from entering the inside of the bridge, causing damage to the busbar or causing safety accidents. It is used to support and fix the main body of the bridge to ensure the stability of the bridge in the installation position. The bracket is generally installed on the ground or the structure of the building, and the hanger is used to suspend the bridge. It is suitable for places with limited space or overhead installation. It should be installed in a dry, well-ventilated, easy-to-check and maintain location according to the layout plan of the substation or distribution room. At the same time, the safe distance between other electrical equipment should be considered to avoid mutual interference and influence. The installation of the bracket and hanger should be firm and reliable, and the spacing should be reasonably determined according to factors such as the type, specification and load-bearing weight of the bridge. Generally, it should not be too large to avoid deformation of the bridge. During the installation process, ensure the verticality and flatness of the brackets and hangers, ensure the horizontality and straightness of the bridge after installation, the connection between the bridges should be tight and reliable, and the connecting bolts should be tightened to prevent loosening. At the same time, in order to ensure the safe operation of electrical equipment, the high-voltage bus bridge must be reliably grounded, and the grounding resistance should meet the requirements of relevant standards. The grounding trunk line should be reliably connected to the bridge, and should be connected to the grounding body at no less than 2 points along the entire length of the bridge. The installation of the high-voltage bus in the bridge should be arranged neatly and the phase sequence should be correct. The connection between the busbars should meet the electrical connection requirements and have good contact. The connection parts should be insulated and sealed to prevent loosening and leakage. The busbar should be fixed with a special fixing fixture, and the spacing between the fixing points should be uniform to ensure that the busbar will not be displaced or vibrated during operation.
