Conductor copper bar for bus duct

Abstract

The invention relates to the technical field of bus duct accessories, in particular to a conductor copper bar for a bus duct, which comprises an insulating plate and a conducting strip, grooves for reducing the thickness of the insulating plate are formed in the upper end face and the lower end face of the insulating plate, a connecting hole penetrates through a body in the middle of the insulating plate, and the conducting strip is provided with a through hole communicated with the connecting hole. After the conducting strips are pressed in the grooves, the connecting holes are poured to form positioning parts, annular parts abutting against the outer end faces of the conducting strips are formed at the two ends of the positioning parts, the creepage distance is increased, meanwhile, the thickness of the insulating plate is reduced, the production cost is reduced, and meanwhile the safety performance of the bus duct is improved.

Description

technical field [0001] The invention relates to the technical field of bus duct fittings, more specifically, it relates to a conductor copper bar for bus ducts. Background technique [0002] The current power consumption is increasing rapidly, especially in high-rise buildings, large public facilities, shopping malls and other places. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. Plug-in bus ducts have emerged as a new type of power distribution wires. Compared with traditional cables, it fully demonstrates its superiority in high current transmission. [0003] The connector of the busway product is equipped with multiple insulating plates with through holes in the middle, and a conductive sheet with a through hole in the middle is arranged on both sides of the insulating plate. After the phase line conductors are insulated from each other and plugged in through the insulation board, they a...

Problems solved by technology

[0006] Since the outer end surface of the phase line conductor row will be wound with an insulating sleeve, the material of the insulating sleeve has hardness, which is extremely inconvenient when winding the bent conductor row manually. Due to the large bending angle, it cannot be realized when the insulating sleeve is wrapped around it. It is completely wrapped and wrapped, and then wrapped with tape, but the tape cannot achieve complete insulation. There will be a gap between the tape and the insulating sleeve, which is also the contact point between the phase wires. The distance is very close. When the current passes When it is large, it will cause the section to be broken down, and a fire will occur, causing a safety hazard
