Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically relating to an integrated AC and DC busbar device. Background Technology

[0002] In current electrical systems, AC and DC power supply often require different wiring layouts and connection devices to transmit electrical energy. For example, in industrial plants, data centers, and other locations, there are numerous devices that use AC power, such as various motors and lighting equipment, as well as some devices that require DC power, such as power modules for some electronic and communication equipment. The traditional approach is to install separate AC and DC busbars, which leads to several problems. First, it occupies a large amount of space. Two independent busbar systems require their own installation space, which can cause layout difficulties and make it hard to arrange wiring rationally in space-constrained locations, such as compact electrical control cabinets. Second, it increases costs. Purchasing, installing, and maintaining separate AC and DC busbars, along with their corresponding connectors and insulation components, increases overall costs, including material and labor costs. Third, it complicates connections. When powering both AC and DC equipment simultaneously, complex switching and wiring are required between different busbar systems, increasing the complexity of wiring connections and increasing the risk of connection errors and other malfunctions.

[0003] For example, Chinese patent CN221978405U discloses a busbar system including a first-phase busbar, a second-phase busbar, and a third-phase busbar, each comprising at least two rows arranged side-by-side. At least one row of each of the first-phase, second-phase, and third-phase busbars has a first current-carrying capacity, and the other rows of each of the first-phase, second-phase, and third-phase busbars, excluding the at least one row, have a second current-carrying capacity, which is less than the first current-carrying capacity. Each of the first-phase, second-phase, and third-phase busbars possesses the first current-carrying capacity. The row includes a first busbar, a first phase busbar, a second phase busbar, and a third phase busbar. Each of these three busbars has a second current-carrying capacity. The first busbar includes a first cross-section taken along a plane perpendicular to its extension direction, and the second busbar includes a second cross-section taken along a plane perpendicular to its extension direction. The area of ​​the second cross-section is smaller than the area of ​​the first cross-section. However, the Chinese patent with publication number CN221978405U does not consider that devices with different requirements for AC and DC power still need two independent busbar systems, which would lead to problems such as large space occupation, high cost, and complex transfer wiring. Utility Model Content

[0004] To address the issues of large space occupation and complex connections in power transmission devices in electrical systems, this invention proposes an integrated AC and DC busbar device that enables simultaneous transmission of AC and DC power within a single busbar device, reducing space occupation, lowering costs, and simplifying connection methods.

[0009] Preferably, the insulating isolation layer is an epoxy resin board, the thickness of which is determined according to the required insulation withstand voltage level. The epoxy resin board has a layered structure and openings for accurately positioning the AC and DC busbars, ensuring electrical clearance, effectively isolating the AC conductive layer and the DC conductive layer, and preventing leakage and mutual interference of electrical energy. The DC busbar and the AC busbar are connected in the openings.

[0010] Preferably, the busbar fixing structure includes fixing holes at both ends of the busbar, and fixing elements are provided in the fixing holes.

[0011] Preferably, the fastener is an M6 bolt, and the fixing hole is a threaded hole that matches the M6 ​​bolt. The copper busbar is fixed in a predetermined position by screwing in the M6 ​​bolt to prevent it from shifting during installation and use.

[0012] Preferably, the modular cabinet structure includes a cabinet fixing plate, which is inverted L-shaped and includes a horizontal plate and a vertical plate. The horizontal plate is perpendicular to the insulation layer, and the vertical plate is parallel to the insulation layer.

[0013] Preferably, the horizontal plate of the cabinet fixing plate is connected to the insulating isolation layer, and the vertical plate of the cabinet fixing plate is connected to the fixing crossbar of the electrical cabinet.

[0014] Preferably, the side of the cabinet fixing plate is provided with a connecting edge, and the connecting edge is provided with a connecting hole.

[0015] Preferably, the protective shell is a transparent PC insulating board, which covers the front and rear of the busbar body respectively. One side of the protective shell is hinged to the busbar body through a damped arbitrary stop hinge to ensure smooth rotation and fixation in any position. The protective shell rotates up and down about the arbitrary stop hinge.

[0016] Preferably, the protective housing is provided with a heat dissipation structure to meet the heat dissipation requirements of the busbar device during long-term operation. The heat dissipation structure is a ventilation hole or a heat dissipation fin.

[0017] The beneficial effects of this utility model are: improved space utilization; simplified installation; ensured uniform current distribution, improving system stability and safety; improved heat dissipation performance, extending the service life of the device; reduced electromagnetic interference; simplified daily maintenance; improved production efficiency, and reduced installation time and cost.
