Embodiment 1

[0101] (Embodiment 1, bus bar for power transmission)

[0102] See Figure 21 , The bus bar for power transmission in this embodiment includes an aluminum bar 3 and two copper-aluminum connecting structural members. The two copper-aluminum connecting structural parts are divided into a first copper-aluminum connecting structural part 1 and a second copper-aluminum connecting structural part 2 .

[0103] See image 3 and Figure 4 The first copper-aluminum connection structure 1 includes a first copper plate 11 and a first cast aluminum plate 12 obtained by casting the first copper plate 11 as an insert.

[0104] See figure 1 and figure 2 , the first copper plate 11 is a stamped pure copper rectangular plate with a thickness of 3 to 5 millimeters (4 millimeters in this embodiment), which includes the first pure copper plate body 11-1, and is set on the first pure copper plate body 11-1 11 connection holes 11-2 on the left and three bolt holes 13 on the right on the first...

Embodiment 2

[0122] (Embodiment 2, bus bar for power transmission)

[0123] The remaining parts of the busbar for power transmission in this embodiment are the same as in Embodiment 1, the difference is that:

[0124] See Figure 7 and Figure 8 , the thickness of the first copper plate 11 of the first copper-aluminum connection structure 1 is 5 to 10 mm (8 mm in this embodiment). The first copper plate 11 also includes a connection groove 11-4. Two connection grooves 11-4 are arranged on the left and right sides, and are divided into a right connection groove 11-4-1 and a left connection groove 11-4-2. The right connecting groove 11-4-1 is opened on the first pure copper plate body 11-1, and is located on the front side of the first pure copper plate body 11-1, and coincides with the position of the first group of connecting holes 11-2-1, The width is slightly wider than the diameter of the first group of connecting holes 11-2-1. The left connection groove 11-4-2 is opened on the firs...

Embodiment 3

[0128] (Embodiment 3, bus bar for power transmission)

[0129] The remaining parts of the busbar for power transmission in this embodiment are the same as in Embodiment 1, the difference is that:

[0130] See Figure 5 and Image 6 , when the first cast aluminum plate 12 is cast, the left end of the first pure copper plate body 11-1 is covered in the first cast aluminum plate 12 from the front; thus the first cast aluminum joint of the first cast aluminum plate 12 12-2 not only includes the first cast aluminum connecting plate 12-2-1 and the connecting column 12-2-2, but also includes the first cladding connecting plate 12-2-4. The first cladding connecting plate 12-2-4 is formed simultaneously with the connecting column 12-2-2 to form a whole, and the rear side of the first cladding connecting plate 12-2-4 is densely connected to the first pure copper plate On the front side of the left part of the body 11-1. The front end surface of the first cladding connecting plate 12...

Abstract

The invention relates to a power transmission bus and a bus assembly thereof. The power transmission bus comprises an aluminum strip and two copper-aluminum connecting components, wherein each copper-aluminum connecting component comprises a copper plate and a cast aluminum plate obtained by casting the copper plate as an embedded component; and one end of the cast aluminum plate and the aluminumstrip are welded together so that the two copper-aluminum connecting components are respectively positioned at both ends of the aluminum strip. The bus assembly for power transmission comprises threeto four buses, a square pipe and two seal blocks, wherein three to four buses are vertically arranged along the left direction and the right direction; rectangular holes matched with the copper-aluminum connecting components are arranged on the two seal blocks, and the two seal blocks are respectively sleeved outside the corresponding copper-aluminum connecting components and inserted at the leftend and the right end of the square pipe; the inner walls of the seal blocks are connected with the copper-aluminum contact position in a seal way, and the outer walls are connected with the inner wall of the square pipe in the seal way. The invention has favorable conductive performance, high reliability and long service life and can form a power line for transmitting low-voltage high-current ata long distance.

Description

technical field [0001] The invention relates to a busbar for electric power supply or distribution and a busbar assembly thereof. Background technique [0002] Industrial and mining enterprises generally use self-built substations for production, office and daily use of electricity. The power supply company sends power to the substation through high voltage, and after converting it into 380V / 220V power, the power is sent to the power cabinets by connecting cables. , and then connect the electrical equipment to the electrical cabinet to obtain electricity. [0003] The traditional structure is to use cables to send power directly. With the increase and centralization of power consumption, in order to reduce line loss, facilitate power distribution and power supply line construction and maintenance, some industrial and mining enterprises have adopted the structure of copper bus power supply. The so-called busbar actually uses copper bars instead of traditional cables to dire...
