Description

Technical Field

[0001] This utility model relates to the field of substation equipment, specifically, it is a fitting for cross-connection of tubular busbars. Background Technology

[0002] At present, new energy projects are developing rapidly, and large-scale new energy projects are equipped with large-scale collection stations. The characteristics of this type of collection station are that the main transformer adopts a double-coil transformer and the low-voltage side of the main transformer has a large capacity, resulting in huge current on the low-voltage side. In order to meet the current carrying requirements, a busbar is usually set on the low-voltage side of the main transformer. Due to the conductor current carrying capacity and site aesthetics, tubular busbars are often used for the busbar.

[0003] There is a situation where the tubular busbars at the low-voltage side outlet of the main transformer are staggered and cross-arranged. The usual solution is to bend the lower-level tubular busbars to the busbars and then connect them with integrated tubular busbar T-connectors. However, due to construction errors and equipment manufacturing errors, the original integrated tubular busbar T-connectors are prone to installation difficulties due to height differences during the installation phase. Furthermore, the following issues can arise when connecting the lower-level tubular busbars with integrated connectors after bending: First, the deformation of the tubular busbars affects the current carrying capacity. Second, the stress released by thermal expansion and contraction of the tubular busbars can be easily transmitted to the higher-level tubular busbars through the integrated tubular busbar T-connectors, leading to deformation of the higher-level tubular busbars. Third, the thermal expansion and contraction of the higher-level tubular busbars can cause the lower-level tubular busbars and support insulators to tilt.

[0004] Traditional solutions consider using four-split steel-cored aluminum stranded wire to replace the bent part of the tubular busbar, but due to the short distance, the steel-cored aluminum stranded wire is prone to strand breakage and has many connection points, which can easily cause overheating. Utility Model Content

[0005] The purpose of this utility model is to provide a hardware for cross-connection of tubular busbars, which solves the problem that during the installation stage of tubular busbar connection, the height difference can easily cause two sets of tubular busbar T-connection hardware to be unable to be installed, and the connection reliability is reduced due to the height difference after long-term use.

[0006] To solve the above problems, the present invention adopts the following technical means:

[0007] A cross-connection fitting for a tubular busbar includes a soft copper stranded wire, with both ends of the soft copper stranded wire connected to a T-type clamp for the busbar and a horizontal clamp for the busbar. The T-type clamp for the busbar is used to connect to a low-profile tubular busbar, and the horizontal clamp for the busbar is used to connect to a high-profile tubular busbar.

[0008] Preferably, the two first clamping plates of the tube T-type clamp are detached and connected by a first bolt and nut mechanism, and the two first clamping plates are detached and connected by six sets of first bolt and nut mechanisms.

[0009] Furthermore, along the axial direction of the T-shaped clamp, three sets of the first bolt and nut mechanisms are symmetrically arranged on both sides of the axis, with the first bolt and nut mechanisms on each side of the axis arranged at equal intervals along the extension direction of the axis.

[0010] Furthermore, the two second clamping plates of the mother pipe horizontal clamp are detached and connected by a second bolt and nut mechanism, and the two second clamping plates are detached and connected by four sets of second bolt and nut mechanisms.

[0011] Furthermore, along the axial direction of the horizontal clamp of the main pipe, two sets of the second bolt and nut mechanisms are symmetrically arranged on both sides of the axis about the axis, and the second bolt and nut mechanisms on each side of the axis are equidistantly arranged along the extension direction of the axis.

[0012] This utility model has the following beneficial effects during use:

[0013] Firstly, it can quickly and easily complete the connection of tubular busbars with staggered vertical arrangements. Secondly, it can reduce the number of tubular busbar connection hardware used, reduce connection points, and reduce heat generation locations. Furthermore, it solves the problem of tubular busbar deformation caused by bending during construction and the problem of installation difficulties caused by height differences in the original integrated tubular busbar connection hardware due to construction errors and equipment manufacturing errors. At the same time, by using soft copper stranded wire combined with tubular busbar T-clamps and tubular busbar horizontal clamps to clamp tubular busbars of different heights, it eliminates the vertical thermal expansion and contraction stress of low-lying tubular busbars and the tilting of low-lying tubular busbars and support insulators caused by thermal expansion and contraction of high-lying tubular busbars.

[0023] Please refer to Figure 1 and Figure 2 As shown, a type of cross-connection fitting for tubular busbars includes a soft copper stranded wire 1.

The tubular busbar T-type clamp 2 is used to connect with a low-profile tubular busbar, and the tubular busbar horizontal clamp 3 is used to connect with a high-profile tubular busbar.
