Description

Technical Field

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

[0002] Bus duct is a metal device composed of metal busbars. It can distribute large power to various components in the circuit system. In buildings, it can replace a large number of wires and cables, making the interior of the building more beautiful and safer. Some fire-resistant bus ducts are not equipped with heat dissipation devices. During use, the internal temperature may be too high, resulting in a fire. At the same time, the outer shell material is not strong enough and no insulation layer is set. There are certain safety hazards during use.

[0003] After searching, it was found that a fire-proof busbar duct was disclosed in the Chinese patent with authorization announcement 202020043616.8, including an upper shell, a lower shell, a limiting mechanism and a connecting mechanism. The cross-sections of the upper shell and the lower shell are both U-shaped, and multiple groups of limiting mechanisms are arranged inside the upper shell and the lower shell. There are multiple groups of limiting mechanisms arranged in an array in a line, and a connecting mechanism is installed on the outer walls of the upper shell and the lower shell. The connecting mechanism includes at least a fixed block and a matching block, the fixed block is fixedly connected to the outer side wall of the upper shell, and the matching block is fixedly connected to the outside of the lower shell, the fixed block is flush with the matching block, and the fixed block is arranged above the matching block, and the bottom end surface of the fixed block is also vertically integrated with a connecting rod.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] This kind of fireproof bus duct is not equipped with a heat dissipation device. When the device is running, the temperature gradually rises. If the temperature is not lowered in time, a fire hazard is very likely to occur. At the same time, no insulation device is provided, and the outer casing may be electrified, which may cause danger to personnel during maintenance. Utility Model Content
