Pouring type bus duct with anti-seismic effect and connection method thereof

Abstract

The invention discloses a pouring type bus duct with an anti-seismic effect and a connecting method thereof.The pouring type bus duct comprises a bus duct shell and an adjusting assembly, a pouring main body is arranged in the bus duct shell, conductor connecting pieces are poured in the pouring main body, and the outer sides of the conductor connecting pieces are wrapped with insulating damping sleeves; a buffer filling plate is filled between the bus duct shell and the pouring body, an elastic buffer block is arranged in the bus duct shell, guide plate grooves are formed in the outer sides of the two ends of the bus duct shell, adjusting guide plates are connected in the guide plate grooves, adjusting grooves are formed in the adjusting guide plates, and clamping grooves are formed in the peripheries of the outer sides of the two ends of the bus duct shell. The two ends of the lower adjusting seat and the two ends of the upper adjusting seat are clamped at the connecting positions of the two bus duct shells respectively, the bus duct shells and the adjusting assemblies are fixedly connected through locking nuts, the problems that bus duct connection is not stable and the anti-seismic effect is poor due to bus duct vibration can be solved, meanwhile, the installation length of the bus duct can be adjusted, and the service life of the bus duct is prolonged. And the bus duct is convenient to install.

Description

technical field [0001] The invention belongs to the technical field of bus ducts, and in particular relates to a casting type bus duct with anti-seismic effect and a connection method thereof. Background technique [0002] The bus duct is a closed metal device composed of copper and aluminum bus bars. It is used to distribute large power to each component of the decentralized system. It has been replaced more and more in indoor low-voltage power transmission trunk projects. Wire and Cable. [0003] Chinese Invention Application Publication No. CN107332183A discloses a shock-proof cast-type fire-resistant bus duct, which includes a plurality of cable troughs for placing cables, an insulating waterproof body for placing the cable trough, a fireproof board arranged outside the insulating waterproof body, and the fireproof board passes through the inner The shell is closely attached to the insulating waterproof body, the outer shell is fixed by screws on the outside of the inne...

AI Technical Summary

Problems solved by technology

An anti-shock pouring type fire-resistant bus duct of the present invention pours insulating resin outside the cable duct, so as to achieve the insulation function and at the same time have a waterproof function; the fire-proof board is sealed inside the shell, which can effectively prevent the damage of the fire-proof board. In order to ensure the normal fireproof performance, there is a fireproof liquid tank on the top of the shell, and the fireproof liquid is sprayed in the busway when it is heated, so as to achieve the purpose of fireproofing. The inner shell and the outer shell are equipped with soft pads, which can prevent shocks Function, the anti-shock casting type refractory busway mentioned above only uses soft pads to resist the shock of the busway, which is far from meeting the requirements for shock absorption of the existing busway by external vibrations, which will only cause the busway to be damaged. The connection is not stable, and the shock absorption effect is poor, which affects the use of the busway, and the existing busway may have a problem of insufficient connection length during installation and connection, which leads to the failure of the normal installation of the busway. For this reason, we propose an anti-seismic Effective casting type busway and its connection method
