Bus duct with dual damp-proof structures

Abstract

The invention discloses a bus duct with dual damp-proof structures. The bus duct comprises a bus duct outer side plate, a copper bar, a cover plate, a placement frame, an observation window, a sealingstrip plate, a detection box, an external drying box, an embedment shell, a sealing groove, a detection rod, an observation ball, a tip port, a sealing plate, a fixed bolt, a sealing ring, an embedment framework, an internal drying pack and a pinboard. The bus dust is reasonable in structural design, the internal drying pack arranged in the bus dust shell is used for drying an internal environment, the external drying pack additionally arranged on the cover plate is used for enabling an external environment of the bus dust to be dried, unfavorable influence on the bus duct caused by excessiveheavy humidity of the external environment is prevented, so that the whole bus duct has a dual-layer damp-proof structure, and the damp-proof performance of the bus duct is improved; and anhydrous cupric sulfate arranged in the detection box and the observation ball is used for monitoring whether the external drying pack and the external drying pack are failure or not, and the situation that thedamp-proof structure is failure caused by failure of the drying packs is prevented.

Description

technical field [0001] The invention relates to a bus duct, in particular to a bus duct with a double moisture-proof structure, and belongs to the technical field of power transmission equipment applications. 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 increasingly replaced wires in indoor low-voltage power transmission main line projects Cable is a common power transmission device. [0003] When the inside of the bus duct is damp or in a humid environment for a long time, there may be water and condensation inside or on the surface of the bus duct, and the accumulated water and condensed dew may cause discharge in most cases, eventually causing the unit to Tripping will have an adverse effect on the transportation of electricity. Therefore, a bus duct with a double moisture-proof structure is proposed to solve ...
