Abstract

The invention relates to a fireproof type bus duct, particularly a fireproof type bus duct with heat dissipation rings. According to the fireproof type bus duct with the heat dissipation rings, coverplates are fixedly arranged at the upper and lower ends of the bus duct; side plates are fixedly arranged on the two sides of the bus duct; heat dissipation rings are fixedly arranged on the side plates; fixed screws are fixedly arranged on the cover plates; fixed gaskets are fixedly arranged on the corresponding fixed screws; a plurality of conductive plates are uniformly arranged in the bus duct; a fireproof filling layer with a rectangular section is fixedly arranged outside the conductive plates; an insulating layer is fixedly arranged outside the fireproof filling layer; and an electromagnetic shielding layer with a rectangular section is fixedly arranged outside the insulating layer. The fireproof type bus duct with the heat dissipation rings is low in cost, creative in design, and high in innovativeness, and the design requirement of the fireproof type bus duct with the heat dissipation rings can be better satisfied.

Description

technical field [0001] The invention relates to a fire-resistant bus duct, in particular to a fire-resistant bus duct with a cooling ring, which is a necessary tool for various power transmission and distribution equipment. Background technique [0002] In the power supply system of high-rise buildings, the main power supply line plays a very important role and is the basis for the good operation of the entire power supply system. Therefore, once a failure occurs, it will cause serious consequences. [0003] In recent years, due to the emergence of bus ducts, the shortcomings of traditional cable trunk lines that need to be specially equipped with power distribution boxes and buried underground pipe branches have been overcome. In addition, bus ducts also have strong structural versatility, strong interchangeability, and line changes. And the advantages of flexible expansion, small line loss, convenient installation, long service life, and high system protection level, so it...
