Adjustable common-box closed bus duct and use method thereof

Abstract

The invention discloses an adjustable common-box closed bus duct. The adjustable common-box closed bus duct comprises a bus duct body; an insulator is fixed on the inner side of the bus duct body; a conducting bar is arranged on the insulator; a guide rail is fixed on one side wall of the bus duct body; a heat shield is arranged on the guide rail; an air inflow groove is formed in the inner side of the bus duct body and corresponds to the heat shield; an asbestos plate is fixed to the inner surface of the heat shield; a sliding groove is formed in the upper end of the inner side of the heat shield; and an adjusting plate is slidably arranged on the inner side of the sliding groove. By means of the asbestos plate, the adjusting plate, the heat shield, a first ventilation hole, a second ventilation hole, a fan and an air guide pipe, influence on an air inflow effect by inconvenient air inflow adjustment is avoided; the ventilation quantity can be adjusted; the air inflow effect can be improved through the fan; and heat dissipation of the inner side of the bus duct body is facilitated. By means of a supporting block, a sealing plate, sealing rubber, a transparent plate and a limiting block, and the sealing plate can be rotationally opened and closed conveniently.

Description

technical field [0001] The invention belongs to the technical field of bus ducts, and in particular relates to an adjustable common-box closed bus duct and a use method thereof. Background technique [0002] The 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 increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. The closed bus duct of the common box has excellent short-circuit resistance performance. Because of the protection of the aluminum (or weak magnetic steel plate) shell, it can effectively reduce the structural heating caused by eddy current or circulating current, reduce the temperature of the closed bus shell, reduce the power loss, and increase the load. flow, mitigating electric power. [0003] During the use of the existing closed busway with shared cabinets, the size of the air inlet i...
