Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a compact and intensive bus duct. Background Art

[0002] Compact and dense bus ducts are suitable for AC three-phase four-wire and three-phase five-wire systems, and are often used as auxiliary equipment for power supply and distribution equipment in industrial and mining, enterprises, institutions and high-rise buildings, in conjunction with the motion imaging of the printed object. During use, the existing compact and dense bus ducts are connected by pressing the side of the conductive busbars with the wire duct connector, which causes the conductive busbars to slide easily during use, thereby causing a short circuit. In addition, the conductive busbars and the outer shell of the existing bus ducts are usually fixed with bolts, which requires specific tools to disassemble the outer shell during maintenance, affecting the maintenance efficiency.

[0003] The publication (announcement) number is CN219592087U, which discloses a compact and intensive bus duct. It includes a conductive bar, a left cover, a right cover, an upper seal and a lower seal. The left cover and the right cover are sleeved on the outer end of the conductive bar. The upper end face and the lower end face of the left cover and the right cover are provided with a slide rail. The lower end face of the upper seal and the upper end face of the lower seal are provided with a slide groove. The upper seal and the lower seal are slidably connected with the left cover and the right cover through the slide groove and the slide rail. Conductive busbars are provided on both sides of the conductive bar. The side end face of the conductive busbar is provided with anti-skid teeth. Protective pads are provided in the left cover and the right cover. The utility model can effectively increase the conductive area of ​​the conductive busbar by providing anti-skid teeth on the side end face of the conductive busbar, thereby reducing resistance and reducing current heat generation, thereby improving the safety of the equipment. At the same time, the anti-skid teeth can effectively prevent the longitudinal sliding of the conductive busbar during the connection process, greatly improving the stability of the equipment.

[0004] Although the above scheme facilitates the disassembly of the bus duct and avoids the displacement of the conductive busbar, the assembly process requires the installation of protective pads, the clamping of side covers, the assembly of seals and the adjustment of latches in sequence. The equipment assembly and disassembly process is relatively complicated, and the conductive busbar lacks positioning in the shell and is easily pulled out of the shell and has general stability. For this reason, we propose a compact and intensive bus duct. Utility Model Content
