Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, in particular to a dense bus duct with a flame retardant structure. Background Art

[0002] The intensive bus duct is a conductor that can replace the traditional cable transmission of electricity. It uses the plug-in method to branch the power supply of the main line to the branch line. The branching is very convenient and widely used. The intensive bus duct is composed of a copper busbar and a shell. Each copper busbar has an insulating medium, and each copper busbar is closely connected to form a three-phase four-wire or three-phase five-wire conductor. The shell is generally grounded. According to the patent document with the authorization announcement number: CN219535569U, the name is "a flame-retardant intensive bus duct". The heat dissipation inside the shell can be achieved through the mutual cooperation of the heat dissipation cylinder, the heat dissipation fan, the frame, and the dustproof net, which avoids the influence of high temperature on the use and reduces the possibility of fire caused by high temperature. The dustproof net can prevent dust from entering when not in use. The mutual cooperation of the L-shaped plate, the slide plate, the knob, the plug block, the rack, the shaft, the gear, the guide column, and the second compression spring can facilitate the disassembly and assembly of the frame, and then facilitate the replacement and cleaning of the dustproof net, which is easy to operate and improves efficiency.
