Description

Technical Field

[0001] The utility model belongs to the technical field of compact bus ducts, and particularly relates to a compact bus duct that is easy to dissipate heat. Background Technique

[0002] As a low-voltage power main line, the compact bus duct mainly consists of 2 upper and lower high plates, 2 left and right side plates, 3 phase conductors (ABC), one N-phase conductor, one PE conductor, as well as insulating materials, waterproof materials, fasteners, etc.; after the conductors are insulated, they are juxtaposed and closely placed in the middle of the bus duct. The upper and lower cover plates and the left and right side plates are riveted together to surround the conductors. Since the conductors of the compact bus duct need to dissipate heat to the surrounding air through the outer shell to maintain the heat balance generated during the operation of the bus duct, especially the B / C2 phase conductors in the middle of the bus duct, the main heat generated during their operation needs to be conducted to the outer shell through the A / C phase and then dissipated to the surrounding air by the outer shell. The heat dissipation effect is poor, the temperature of the bus duct is high, which affects the current-carrying capacity and safe operation.

[0003] The Chinese patent with the authorized announcement number of CN220139194U discloses a compact bus duct, which includes a base plate. Fixed vertical plates are welded to the front and rear sides of the top of the base plate. A bus bar plate is connected to the middle of the top of the base plate by bolts. The top of the front and rear two fixed vertical plates is connected to a top cover plate by bolts. A fixed shell is welded to the top of the top cover plate. An insect repellent mechanism is slidably connected through the front side of the fixed shell. An installation shell is connected and welded to the top of the fixed shell in communication. A heat dissipation fan is connected to the inner cavity of the installation shell by bolts. Dust-proof mechanisms are slidably connected to the left and right sides of the top cover plate.

[0004] The above patent uses the method of accelerating the internal air circulation for heat dissipation. There are gaps between the conductors for air-cooled heat dissipation and it is connected to the external environment, which reduces the service life of the conductors and the insulation layer. Therefore, a new device needs to be designed. Content of the Utility Model
