Trapezoidal plug-in interface type high-thermal-conductivity pouring bus duct connector

Abstract

The invention discloses a trapezoidal plug-in interface type high-thermal-conductivity pouring bus duct connector which comprises a trapezoidal notch connector and a bus duct. The adjacent bus ducts are connected through a trapezoidal notch connector; a plurality of plugging ports are formed in the trapezoidal notch connector; a bus copper bar is arranged in the bus duct, a first bus copper bar connector and a second bus copper bar connector are arranged at the two ends of the bus copper bar, when adjacent bus ducts are connected, the first bus copper bar connector is attached to one side of the insertion port, and the second bus copper bar connector is attached to the first bus copper bar connector and the other side of the insertion port. The sleeve connector is manufactured, the two ends of the bus are connected in an inserting mode, related components and in-situ pouring and demolding procedures are omitted, and the effect of rapid and convenient in-situ connection and installation of the bus duct is achieved; the copper bars at the two ends of the bus duct are fixed through the high-thermal-conductivity connector, and the effects of reducing the temperature of the bus joint and improving the operation reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of bus bars, in particular to a trapezoidal plug-in port type high thermal conductivity cast bus duct connector. Background technique [0002] Bus ducts have increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. The cast busway is made of high-performance insulating resin and a variety of inorganic minerals, and is designed with a reasonable "sandwich" phase line tightly stacked structure. However, the traditional cast-in bus duct joints are connected by connecting copper bars, which leads to the increase of contact resistance and serious joint heating, and there are many connectors and installation molds when the cast-in bus duct is connected, which affects the installation efficiency. [0003] Special corundum ceramic material has good thermal conductivity, mechanical strength and high temperature resistance. Because of its superior performance, it has been widely...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention proposes a trapezoidal socket-type high thermal conductivity pouring busway connector, which is prefabricated in the factory and connects both ends of the busbar by plugging, which solves the problem of traditional pouring busway connection. There are many connectors and installation molds that affect the installation efficiency; the copper bars at the end of the bus duct are fixed by the high thermal conductivity trapezoidal notch connector, which solves the problem of increased contact resistance caused by the connection of the traditional cast-type bus duct joints through the connecting copper bars. Serious problems with joint heating
