Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an adjustable conductive busbar of a high-voltage power distribution cabinet. Background Art

[0002] Conductive busbars are usually used in power distribution products such as small circuit breakers and molded case circuit breakers. In high-voltage power distribution cabinets, conductive busbars play the role of transmitting current and connecting electrical equipment in the circuit. Existing conductive busbars are basically made of metal copper as raw material, and their cross-section is usually a long conductor with a rectangular or chamfered (rounded) rectangle to minimize the generation of tip discharge. In application, the conductive busbar can be used to connect several adjacent electrical cabinets or for electrical connection between specific power distribution products inside the electrical cabinet.

[0003] However, when existing high-voltage distribution cabinets use conductive busbars for high-power power connection, the conductive busbars are generally fixed and cannot be adjusted according to the connection length of the energy-saving conductive busbars installed between two electrical equipment, so that the conductive busbars cannot be used for connecting electrical components inside different high-voltage distribution cabinets. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an adjustable conductive busbar for a high-voltage distribution cabinet to solve the technical problem that the existing conductive busbar is generally fixed and cannot be adjusted according to the connection length of the specific energy-saving conductive busbar installed between two electrical equipment, so that the conductive busbar cannot be used for connecting electrical components inside different high-voltage distribution cabinets.

[0005] According to the technical solution provided in the embodiment of the present application, an adjustable conductive busbar of a high-voltage power distribution cabinet includes an adjustment mechanism installed at the connection between a first conductive busbar and a second conductive busbar, and used for adjusting the connection length between the first conductive busbar and the second conductive busbar;

[0006] The adjustment mechanism includes an adjustment bolt, a gear and two racks. The two racks are staggered and fixedly installed in the first connecting groove and the second connecting groove provided on the first conductive busbar and the second conductive busbar, and each rack is meshed and connected with the gear. The gear is fixedly connected to the output end of the adjustment bolt so that the adjustment bolt rotates clockwise to adjust the connection length of the connection between the first conductive busbar and the second conductive busbar.

[0007] Furthermore, the first conductive busbar is provided with a plurality of first card slots and a plurality of first card blocks, and the second conductive busbar is provided with a plurality of corresponding second card blocks and a plurality of second card slots, each of the second card blocks is connected to each of the first card slots, and each of the first card blocks is connected to each of the second card slots.

[0008] Furthermore, the first card slot and the second card block have compatible structures, and the first card block and the second card slot have compatible structures, and the first card slot, the second card block, the first card block and the second card slot are all rectangular structures.

[0009] Furthermore, the rack is in a straight bar structure.

[0010] Furthermore, the adjusting bolt, the gear and the two racks are all made of insulating materials.

[0011] In summary, the beneficial effects of this application are:

[0012] 1. By setting an adjustment mechanism at the connection of two connected conductive busbars, the adjustment mechanism can adjust the connection length of the two conductive busbars, so that the conductive busbar can be used for the connection between two power transmission cabinets with different spacings in different high-voltage distribution cabinets, thereby improving the use efficiency of the conductive busbar;

[0013] Second, by arranging a first card slot, a first card block, a second card slot, and a second card block that can be mutually snap-connected on two connected conductive busbars, two adjacent conductive busbars can be snap-connected to replace the original flat-plate connection, thereby increasing the stability of high-power current transmission between the two conductive busbars and improving the conductive efficiency of the conductive busbars.
