Problems solved by technology

[0003] In the prior art, the expansion unit of the busway is generally solved by the expansion and contraction of the sleeve. Due to the rigidity of the sleeve, the expansion unit of the sleeve can only be adjusted in one direction along the direction of the sleeve, and cannot meet any angle. adjustment requirements

Embodiment 1

[0027] like figure 1 , figure 2 As shown, a low-voltage busway universal expansion unit according to the present invention includes two sections of busway 1, 1' with housings 11, 11' and conductive bars 12, 12', two sections of busway 1, 1 The conductive bars 12, 12' are softly connected by flexible wires 2, and a part of the two bus duct housings 11, 11', as well as the outer cover of the conductive bars 12, 12' and the flexible wires 2 are provided with a belt. Boxes 3, 3' with side openings, the openings of the two boxes 3, 3' are set on one side of the flexible wire, and the two boxes 3, 3' are provided with a structure so that the two bus ducts 1, 1' have Axial moving device for relative displacement. The box body 3, 3' is also provided with a longitudinal moving device for relative displacement of bus duct 1, 1' in a direction perpendicular to the axial direction.

[0028] like figure 1 , figure 2 As shown, the axial moving device includes movable end plates 4, 4' ...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 5 , Image 6 As shown, in the two sliding side plates 6, 6', the oblong direction of the pin groove 62 at the four corners of one of the sliding side plates 6 is set along the diagonal direction of the corner, and the other sliding side The oblong orientation of the pin grooves 62' at the four corners of the plate 6' is perpendicular to the orientation of the aforementioned diagonal. Its working principle is completely the same as that of Embodiment 1, and will not be repeated here.

Abstract

The invention belongs to the technical field of low-voltage bus slot products, and particularly discloses a universal expansion unit for a low-voltage bus slot. The universal expansion unit comprises two sections of bus slots with casings and conducting bars, the conducting bars of the two sections of bus slots are connected through a soft conductive wire in a soft way, a box body with an opening on the side is arranged on part of the two bus slot casings and periphery covers of the conducting bars and the soft wire, the opening of the box body is arranged on one side of the soft conducting wire, an axial moving device enabling the two bus slots to relatively shift in an axial direction is arranged on the box body, and a longitudinal moving device enabling the bus slots to relatively shift in the direction perpendicular to the axial direction is further arranged on the box body. According to the expansion unit, the position adjustment of the bus slots at any angle and in any direction can be realized, the use is convenient and reliable, the application scope is wide, and the electronic performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of low-voltage busway products, and specifically discloses a low-voltage busway universal expansion unit. Background technique [0002] The busway for power supply system is an important transmission channel for transmitting powerful power in important places such as buildings, hospitals, industrial plants, gymnasiums, conference centers or airports, stations, commercial plazas, etc. With the development of modern industry, the application of busway is more and more widely. When wiring between different buildings, etc., busway expansion unit is needed to absorb the axial change of busway due to thermal expansion and solve the problem. The additional stress caused by temperature difference and mechanical vibration acts as an elastic compensation element. For example, when the length of the bus duct exceeds 80m, an expansion bus duct unit can be installed. [0003] In the prior art, the expansion unit of the...
