Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a compact busbar. Background Technology

[0002] As a key component of modern power distribution systems, busbar trunking is essentially a high-capacity power transmission solution that replaces cables. It consists of conductive bars encased in a metal shell, forming a closed power transmission channel. Compared to traditional cables, this structure has higher current carrying capacity and better heat dissipation performance. The modular design of busbar trunking allows for flexible length expansion according to power demand, and its standardized interfaces simplify the installation and modification process of power distribution systems. It has shown significant advantages in centralized power supply scenarios such as industrial plants, high-rise buildings, and data centers.

[0003] High-density busbar trunking is a product of busbar trunking technology iteration. It achieves a more compact structural design by optimizing the internal space layout. Its core feature is the dense arrangement of conductor bars with minimal electrical clearance, combined with high-performance insulation materials to ensure safe operation. This design significantly increases the current transmission density per unit volume, making it particularly suitable for applications with limited space but high power demand. At the same time, it integrates fireproof, moisture-proof and mechanical protection functions through a multi-layer protective structure, meeting the dual requirements of modern power systems for safety and space efficiency.

[0004] Traditional high-density busbar trunking has revealed deficiencies in its protection system in practical applications. Its basic design often only considers the power transmission function under normal operating conditions and lacks multi-dimensional protection measures to cope with complex environments. The insulation material's insufficient high-temperature resistance increases the risk of fire. The simple anti-corrosion treatment of the outer shell is difficult to resist the erosion of moisture or corrosive gases. The single level of mechanical protection cannot effectively buffer external impacts. These shortcomings restrict its reliability in special environments such as chemical, marine or high-temperature industries. Utility Model Content

[0005] The purpose of this invention is to provide a compact busbar trunking system that solves the problem of lack of protective measures in traditional compact busbar trunking systems.

[0006] To achieve the above objectives, this utility model provides a high-density busbar trunking system, comprising a busbar trunking body, with cover plates fixedly installed at the top and bottom ends of the busbar trunking body, side plates fixedly installed at the left and right ends of the cover plates, and a vertical plate fixedly installed between the two side plates. The busbar trunking body has an internal placement slot, and a copper busbar is fixedly installed inside the placement slot. An insulating sleeve is fitted around the outer ring of the copper busbar. The busbar trunking body is equipped with fireproof components. The busbar trunking body, as the core frame, bears the overall structural weight and maintains the stability of the internal components. The cover plates cover the top and bottom openings to prevent dust and foreign objects from entering while also assisting in heat dissipation. The side plates close the left and right sides to form a complete protective shell and cooperate with the vertical plate to enhance the resistance to deformation. The vertical plate is arranged vertically between the side plates to provide additional support and reduce deformation caused by vibration. The placement slot precisely accommodates the copper busbar and limits its movement range to ensure constant electrical clearance. As a conductive core component, the copper busbar bears the task of transmitting large currents and must maintain surface flatness to reduce impedance. The insulating sleeve tightly wraps the surface of the copper busbar to block leakage current to ground and withstands high-temperature aging.

[0007] The fireproof component includes fireproof filler. Fireproof filler is fixedly installed on the outside of the placement groove. Fixing blocks are fixedly installed at the upper and lower ends of the cover plate. The fireproof filler uses inorganic material to fill the gaps between cables to slow down the spread of flames. The fixing blocks are welded to the edge of the cover plate to provide mechanical connection support for the overall installation.

[0008] The fixing block has mounting holes at both ends and a protective plate is fixedly installed at both ends. The mounting holes penetrate the fixing block, allowing bolts to pass through for quick assembly or disassembly. The protective plate covers the outside of the fixing block to prevent external mechanical damage while hiding the connecting bolts and improving aesthetics.

[0009] The protective plate is fixedly connected to the fixing blocks at the upper and lower ends by the first fastening bolt. The first fastening bolt locks the protective plate on the fixing block to maintain the stability of the interface.

[0010] The copper busbar has an anti-oxidation coating sprayed on the outer side near the protective plate. The anti-oxidation coating is attached to the surface of the copper busbar by chemical vapor deposition to inhibit the formation of oxide film.

[0011] The cover plate is fixedly connected to the main body of the busbar trunking by a second fastening bolt. The outer layer of the cover plate and the side plate is coated with an anti-corrosion coating. The second fastening bolt penetrates the threaded hole of the cover plate and the main body to achieve a detachable and sealed connection. The anti-corrosion coating is based on epoxy resin to protect the metal shell from moisture corrosion.

[0012] The anti-corrosion coating is coated with a fireproof coating on its outer layer, and the fireproof coating is coated with an insulating coating on its outer layer. The fireproof coating expands at high temperature to form a heat insulation layer, which slows down the heat conduction rate. The insulating coating, as the outermost covering, provides additional electrical isolation and improves surface wear resistance.

[0013] Safety performance is significantly enhanced through multiple protective designs. The outer layer of the copper busbar is wrapped with an insulating sleeve to effectively isolate the risk of current leakage. Fireproof filler tightly surrounds the placement slot to form a high-temperature barrier layer. The protective plate and fixing block work together to protect the internal structure from external impacts. The superimposed spraying of anti-corrosion coating, fireproof coating and insulating coating achieves triple protection of corrosion resistance, flame retardancy and insulation. Anti-oxidation coating delays the oxidation of the copper busbar surface. The whole protection system ensures long-term stable operation of the equipment in complex environments. The cover plate is quickly connected to the main body with fastening bolts to facilitate internal maintenance. The fixed block has pre-set standardized installation holes to simplify the external docking process. The protective plate can be quickly spliced ​​with adjacent busbars with fastening bolts. The vertical plate enhances the overall structural rigidity and reduces the risk of deformation. All connecting parts adopt a detachable design, so that partial replacement or upgrade does not require disassembling the entire structure, which greatly reduces construction and maintenance costs.
