High-safety intensive bus duct

Abstract

The invention discloses a high-safety intensive bus duct. The high-safety intensive bus duct comprises a duct body, a mounting structure, a heat dissipation structure and a connecting structure, the duct body is an aluminum alloy duct body, and electrostatic powder is sprayed on the outer surface of the duct body; the mounting structure is arranged at the upper end of the duct body; the heat dissipation structure is arranged in the duct body; the connecting structure is arranged at the opening in the left side of the duct body; the power distribution cabinet also comprises copper bars, wire boxes and a cover plate. The wire boxes are symmetrically arranged in the heat dissipation structure; the outer surfaces of the middle parts of the copper bars which are uniformly arranged are sleeved with flame-retardant cross-linked polyethylene heat-shrinkable sleeves; and gaps of the flame-retardant cross-linked polyethylene heat-shrinkable sleeves sleeving the outer surfaces of the adjacent copper bars are filled with silicone grease. According to the high-safety intensive bus duct, the structural design is reasonable, the bus duct is convenient to mount and dismount, the position of the bus duct is convenient to adjust, heat dissipation is faster, a fire source can be effectively isolated, the service life of the bus duct is prolonged, and leveling is facilitated when the bus duct is mounted.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a high-safety intensive bus duct. Background technique [0002] 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 been increasingly replaced in indoor low-voltage power transmission main line projects. Wires and cables have become an indispensable wiring method in high-rise buildings, factories and other electrical equipment and power systems. Due to the needs of various buildings such as buildings and factories, and this demand is increasing year by year, using the original The way of circuit wiring, that is, the way of passing through pipes, brings many difficulties during construction.

[0002] 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 been increasingly replaced in indoor low-voltage power transmission main line projects. Wires and cables have become an indispensable wiring method in high-rise buildings, factories and other electrical equipment and power systems. Due to the needs of various buildings such as buildings and factories, and this demand is increasing year by year, using the original The way of circuit wiring, that is, the way of passing through pipes, brings many difficulties during construction. Moreover, when it is necessary to change the power distribution system, it is almost impossible to make it simpler. However, if busway is used, it is very easy. To achieve the goal, it can also make the building more beautiful, but the installation and disassembly of the traditional busway is inconvenient. After installation, it is troublesome to adjust the position of the busway. The service life is low, so it is imperative to propose a high-security intensive busway
