Problems solved by technology
The current busway will generate heat to varying degrees during operation, and a series of adverse phenomena will occur when the temperature rises
For example, the temperature rise directly affects the loss of electric energy, the aging of insulating materials is fast, the service life of the busway is shortened, the stress of the metal conductor begins to relax after being heated, which reduces the mechanical strength, and the mechanical strength of the busway is also reduced. Insulation material equipment accelerates aging (such as wires and cables or electrical insulation supports that are adjacent to or transferred to the busway), and may even easily cause fire accidents
However, most of the existing bus ducts are fully enclosed or semi-enclosed in order to prevent dust or water vapor from entering the interior, and the internal air cannot flow effectively, resulting in heat accumulation in high-heating parts, which cannot effectively cool down, let alone two adjacent bus ducts. Mutual flow in the tank

The invention discloses a heat dissipation device for a bus duct connecting plug, and belongs to the technical field of power transmission equipment. The device comprises a plug and a connecting sideplate. The connecting side plate is connected with a bus duct through a plug. Each connecting side plate comprises a closed baffle and a side connecting sheet. The side connecting pieces are perpendicularly connected with the closed baffle, the cooling fins are arranged on the outer sides of the side connecting pieces in an array mode, the circulating air ducts are arranged in the connecting sideplates, penetrate through the closed baffle and extend to the front ends of the side connecting pieces from the interiors of the side connecting pieces, and the circulating air ducts are provided withcirculating air duct openings in the front ends of the closed baffle and the side connecting pieces. The parts, positioned in the side connecting pieces, of the circulating air ducts are alternatelybent and coiled up and down. The two groups of circulating air ducts are communicated with the two adjacent groups of bus ducts, so that air in the two adjacent groups of bus ducts can circulate mutually, heat is effectively dissipated through the heat dissipation fins on the outer sides of the side connecting pieces, heat is prevented from being accumulated at high heating parts in the bus ducts,the performance of the bus ducts is prevented from being influenced, and the service life and reliability of the bus ducts are reduced.
Description
technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a heat dissipation device for connecting plugs of bus ducts. Background technique [0002] The busway is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the decentralized system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. [0003] With the increasing development of modern construction, the utilization rate of busway is getting higher and higher, so it is urgent to improve the quality of busway. The current busway will generate heat to varying degrees during operation, and a series of adverse phenomena will occur when the temperature rises. For example, the temperature rise directly affects the loss of electric energy, the aging of insulating materials is fast, the service life of the busway is shortened, the...
