Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically to an adjustable capacity busbar plug-in box power take-off component. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly, especially with the appearance of numerous high-rise buildings and large factory workshops. Traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbar trunking, as a new type of power distribution conductor, has emerged. Compared with traditional cables, busbar trunking fully demonstrates its superiority in high-current transmission. At the same time, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points at both ends of the busbar trunking and the plug-in points of the branch ports are greatly reduced. High-quality insulation materials are used in the busbar trunking, thereby improving the safety and reliability of the busbar trunking and making the entire system more complete.

[0003] A plug-in box is a junction unit connecting the copper busbars of a busbar trunking to the cables. Its function is to draw power from the plug-in interfaces on the busbar trunking and distribute the power to the electrical equipment via a switch inside the plug-in box. A plug-in box typically includes a casing, an air switch, and pins that mate with the plugs in the busbar trunking. Current flows from the busbar trunking through the pins to the air switch, and then from the cable electrically connected to the air switch to the electrical equipment. Existing busbar plug-in boxes achieve variable capacity by changing the size and specifications of the pins. However, different pin sizes may not match the busbar trunking plugs, reducing applicability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an adjustable capacity busbar plug-in box power supply component. This solves the problem that existing busbar plug-in boxes achieve variable capacity by changing the size and specifications of the plugs, but the plugs of different sizes and specifications may not match the busbar slots, reducing their applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable capacity busbar plug-in box power take-off assembly includes an insulating housing, the insulating housing including a support plate, guide plates symmetrically arranged on both sides of the top end face of the support plate, multiple insulating baffles arranged on the top end face of the support plate between the two guide plates, and an insulating isolation sleeve arranged on the bottom end face of the support plate. Multiple evenly distributed receiving slots penetrating the support plate are opened in the insulating isolation sleeve. The receiving slots are divided into two plug compartments by insulating partition plates. The plug compartments are detachably provided with plugs for plugging and mating with each phase busbar.

[0007] As a preferred embodiment of this utility model, the support plate is provided with multiple mounting holes.

[0008] The above technical solution facilitates the installation of the insulating housing by utilizing the mounting holes.

[0009] As a preferred technical solution of this utility model, a PE pin groove is provided on one side end face of the insulating sleeve, and a PE pin is provided in the PE pin groove. The PE pin is a single-sided contact type.

[0010] The above technical solution utilizes a single-sided contact PE pin to facilitate contact with the inner wall of the aluminum alloy shell, thereby achieving the purpose of using the shell as PE.

[0011] As a preferred technical solution of this utility model, protective plates are provided on the insulating isolation sleeves on both sides of the PE pin slot.

[0012] The above technical solution utilizes a protective plate to protect the PE pins.

[0013] As a preferred embodiment of the present invention, a first sealing groove is provided on the top end face of the bearing plate, and a second sealing groove is provided on the bottom end face of the bearing plate.

[0014] By utilizing the above technical solution and the setting of the first sealing groove and the second sealing groove, sealing gaskets or adhesive can be installed in the first sealing groove and the second sealing groove, thereby improving the protection (IP) level between the power taking components, the plug-in box and the busbar trunking.

[0015] As a preferred technical solution of this utility model, a plurality of fixing holes are provided on the top end face of the bearing plate on the outer side of the opening end of the pin compartment for inserting fixing pins to limit and fix the pins.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model adopts a fully protected plug design, eliminating the need for busbar trunking plug components. The current capacity can be adjusted using a single mold. Multiple current capacities can be achieved simply by adjusting the number and specifications of the plugs, thus saving on molds.

[0018] 2. By setting the first sealing groove and the second sealing groove on the bearing plate, this utility model can install sealing gaskets or apply glue in the first sealing groove and the second sealing groove, thereby improving the protection (IP) level between the power taking components, the plug-in box and the busbar.

[0019] 3. In this utility model, the busbar / conductor does not need to be equipped with a socket device (similar to the fact that there is no need to install a power strip / socket when connecting electricity at home). The socket, socket and plug are combined into one, and the power is directly drawn from the conductor / busbar. There is no need to install a separate socket device. It has both the stability and high protection of the fixed socket busbar trunking and the freedom of multi-point power drawing of the track-type busbar trunking. Attached Figure Description
