Hollow four-side connector

Abstract

The pipe bus end calibre of the inventive hollow four-side joint copper, aluminium pipe bus and copper multiple tube bus (steel pipe or aluminium pipe is claded in the copper pipe) is moulded into four hollow copper and aluminum conducting surfaces by a punching technology. The suitable mould are configured according to actual carrying capacity requirement and the requirement of bus calibre, to process the conducting surfaces (shapes such as a square, a rectangle and two plane ellipse). Since it is an integrated one withou link bit and contacting resistance, thus ensuring the end of the bus will not have a high temperature, and will have safe operation.

Description

technical field [0001] The hollow four-sided joint of the present invention is especially suitable for connecting the bus bar of the conductive pipe and the equipment for conveying power frequency and large current. Large current carrying capacity, low temperature rise, high mechanical strength, and improved operating safety factor. Background technique [0002] The existing conductive pipe busbar joint (patent number: 01215457.1) has the following disadvantages in the actual installation process: since the conductive pipe busbar is circular, it is necessary to install conversion fittings during the connection process with the equipment, from a round surface to a plane, through Rectangular conductors connect with other devices. 1. It is necessary to install conversion fittings to connect the pipe busbar to the equipment, which is costly, wastes materials and consumes energy. 2. The original joint has only two conductive planes, the cross-sectional a...

[0002] The existing conductive pipe busbar joint (patent number: 01215457.1) has the following disadvantages in the actual installation process: since the conductive pipe busbar is circular, it is necessary to install conversion fittings during the connection with the equipment, from a round surface to a plane, through Rectangular conductors to connect with other equipment

1. The connection between the pipe busbar and the equipment needs to be equipped with conversion fittings, which is costly, wastes materials, and consumes energy

2. The original joint has only two conductive planes, the cross-sectional area is small, and the conductors are split. When the current is transmitted, there will be uneven current distribution. One of the conductive plane conductors has a small overcurrent, and the other conductive plane conductor has overcurrent If it is too large, the side with high overcurrent will generate high temperature

3. The connection between the end of the pipe busbar and the conversion fitting will generate contact resistance. Due to the existence of contact resistance, in the case of high current transmission, the end of the pipe busbar and the conversion fitting will generate excessive heat. The greater the heat, the higher the resistance , the more serious the heat is, the higher the temperature will cause the pipe busbar to be blown, short circuit between phases, short circuit to ground or cause a fire and cause a greater accident
