Hollow four plane tie-in

Abstract

The invention relates to a hollow four-face connector, wherein it end diameter of tube main line is punched into hollow four-plane conductive plane; and it is integral without connecting part, it has low contact resistance, to avoid high temperature at end.

Description

Technical field [0001] The hollow four-plane joint of the present invention is particularly suitable for the connection of the busbar of the conductive tube that transports the power frequency large current and the equipment. The current carrying capacity is large, the temperature rise is low, the mechanical strength is high, and the operating safety factor is improved. Background technique [0002] The existing conductive tube busbar connector (patent number: 01215457.1) has the following shortcomings in the actual installation process: Since the conductive tube busbar is round, it is necessary to install conversion fittings during the connection with the equipment, and the round surface is converted into a flat surface. The rectangular conductor is connected to other equipment. 1. The connection between the tube bus and the equipment needs to be equipped with conversion fittings, which is costly, wastes materials and consumes energy. 2. In the original join...

Problems solved by technology

[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. In the original joint, only two conductive plane conductors are split, and there will be uneven current distribution when the current is transmitted. One of the conductive plane conductors has a small overcurrent, and the other one has a large overcurrent. The big side 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
