Description

Technical Field

[0001] The utility model relates to the technical field of power busbars, in particular to a power busbar connecting device. Background Art

[0002] With the progress and development of power technology, high current transmission of electric energy is becoming more and more common. Traditional cables as transmission conductors can no longer meet the requirements in high current transmission systems. The parallel use of multiple cables also brings many inconveniences to on-site installation and construction. Compared with traditional cables, insulated tube busbars with large current carrying capacity fully demonstrate their superiority and have been widely used in high current transmission systems.

[0003] Because the insulated tube busbar is a hard conductor, it is produced in sections in the factory and then shipped to the power transmission and transformation site for installation and connection, so there are many intermediate connecting joints in the insulated tube busbar.

[0004] At present, most of the connections between tubular busbars in the industry are made by making separate joints, which are then fastened with bolts or welded to the joints and the two tubular busbars using C-shaped steel pipes, thereby tightly connecting the two tubular busbars.

[0005] However, the existing connection type between the tube busbars has the following problems:

[0006] 1. The joint is large in size, consumes a lot of metal materials, has low installation efficiency, high production cost, and occupies a large installation space;

[0007] 2. The steel material used is prone to form eddy currents, resulting in large power loss. In addition, the joint surface is irregular and uneven, making it inconvenient to carry out insulation treatment, which reduces the safety and reliability of the operation of electrical equipment.

[0008] Therefore, there is an urgent need to develop a new and efficient type of connection between insulating tube busbars to solve the above-mentioned shortcomings and difficult problems existing in the current power industry. Utility Model Content

[0009] In view of this, the purpose of the utility model is to design a new way of separating rainwater and sewage, and to propose a power bus connection device with a simple and reasonable structural design and easy installation, which can make the connection of the power bus more convenient, quick and practical, fill the gap in supporting equipment in the market, reduce the waste of electric energy, and improve the operating reliability of electrical equipment.

[0010] The utility model provides a power busbar connecting device, which connects two power busbars, comprising:

[0011] A busbar core body and a sheathing assembly, wherein the sheathing assembly is sheathed on the outside of the busbar core body; the sheathing assembly comprises: a busbar connecting device, an insulating sleeve, and a busbar insulating layer connecting device, which are sheathed in sequence from the inside to the outside;

[0012] The busbar connecting device is connected between the ends of the two power busbars, and the two busbars are reliably electrically connected through the busbar connecting device;

[0013] The busbar insulation layer connection device fixes the connection between two power busbars to prevent the busbar connection from loosening or falling off, and performs insulation treatment on the busbar connection to prevent adverse consequences caused by electrical leakage.

[0014] Usually, in actual use, the wire diameters of the two power busbars are the same, and there will not be a situation where one power busbar is larger than the other, and there is no special requirement for the length of the connected power busbars.

[0015] Furthermore, the busbar insulation layer connection device adopts any one of the types of heat shrink tube and insulating tape winding to ensure that the busbar connection is fully fixed.

[0016] The busbar insulation layer connection device is used to reinforce and insulate the busbar connection. The busbar insulation layer connection device uses an insulating heat shrink tubing, which can easily and quickly connect and reinforce the two busbars reliably, and insulate the interface, effectively reducing the waste of electrical energy.

[0017] Furthermore, the insulating sleeve is made of flame-retardant insulating material or flame-retardant insulating material to prevent leakage.

[0018] There are no special requirements for the flame-retardant insulating material or flame-retardant insulating material used in the insulating sleeve for different power transmission and distribution powers.

[0019] Furthermore, the busbar connecting device uses conductive material to ensure reliable transmission of electrical energy.

[0020] In practical applications, it is necessary to consider the current carrying capacity of the conductive material used in the busbar connection device under different power transmission conditions, and at the same time, the power transmission part of the power busbar is preliminarily fixed.

[0021] Furthermore, the busbar core body is made of conductive material and is used for transmitting electrical energy.

[0022] Furthermore, the flame-retardant insulating material used for the insulating sleeve includes: any one of flame-retardant polyvinyl chloride (PVC) and flame-retardant ethylene-propylene rubber (EPDM).

[0023] Polyvinyl chloride is cheap, has good insulation performance and flame retardancy, and is used in flame-retardant wires and cables. In order to improve the flame retardancy of PVC, halogen flame retardants (decabromodiphenyl ether), chlorinated paraffin and synergistic flame retardants are often added to the formula to improve the flame retardancy of polyvinyl chloride.

[0024] Flame retardant ethylene propylene rubber EPDM is a non-polar hydrocarbon with excellent electrical properties, high insulation resistance and low dielectric loss.

[0025] Furthermore, the conductive material used in the busbar connecting device includes: any one of carbon fiber, conductive polymer, and conductive high molecular material.

[0026] Carbon fiber is a fiber composed of carbon with atomic number 6. It has the advantages of light weight, high strength, high modulus and good conductivity. Because carbon fiber has non-metallic properties, it has gradually become an important non-metallic conductive material. Carbon fiber is widely used in aerospace, automobile, high-speed rail and other fields.

[0027] Conductive polymer material is a polymer material with conductive function. Conductive polymer material has the advantages of light weight, flexibility and strong plasticity. It is widely used in organic light-emitting diodes, transistors, solar cells and other fields.

[0028] Conductive polymer material is a composite material with a polymer matrix and conductive additives. It has the characteristics of good conductivity and high plasticity. Conductive polymer materials are widely used in electronics, communications, aerospace, automobiles, new energy and other fields.

[0029] Furthermore, the conductive material used for the busbar core body includes: any one of copper busbar and aluminum busbar, or a combination of the two.

[0030] Copper busbar has high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful metallic luster and good forming and processing performance, etc. Therefore, various power transmission and transformation, electrical equipment, etc. made of it have been widely used in the power field.

[0031] Aluminum busbar is one of the key equipment materials in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment. Aluminum alloy tube busbar tube is mainly used in the conductor connection between the power transmission line and the transformer of the substation in the power construction project, the jumper in the transmission line, the connecting conductor in the power equipment, and the overcurrent conductor in the large current DC ice melting device. It is a new conductor that replaces the traditional rectangular, trough, rod-shaped busbar and soft wire. It is one of the key equipment materials in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment.
