Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum busbar trunking, and particularly relates to a heat-insulated, high-density aluminum busbar trunking. Background Technology

[0002] Compact aluminum busbar trunking is suitable for AC three-phase four-wire and three-phase five-wire power supply and distribution systems. It is wound with flame-retardant cross-linked polyethylene heat-shrink tubing, providing strong insulation performance and preventing the release of toxic gases in the event of a fire.

[0003] Existing compact aluminum busbar systems consist of an aluminum plate as the protective shell, conductive bars, insulation materials, heat dissipation fins, and other accessories. Compact aluminum busbars can be manufactured as plug-in type enclosed busbars with plug-in junction boxes at intervals, or as feeder type enclosed busbars without junction boxes in the middle to improve power transmission efficiency.

[0004] Existing heat-insulated dense aluminum busbar trunking relies mainly on heat dissipation fins installed on the outer casing for heat dissipation. Since the heat dissipation fins are usually distributed in a sheet-like pattern, dust easily accumulates on the surface of the fins after long-term use, thus affecting the heat dissipation efficiency of the fins. Utility Model Content

[0005] This utility model provides a heat-insulated compact aluminum busbar trunking, which aims to solve the problem that the heat dissipation of existing heat-insulated compact aluminum busbar trunking mainly relies on heat dissipation fins installed on the outer shell. Since the heat dissipation fins are usually distributed in a sheet-like pattern, dust easily accumulates on the surface of the fins after long-term use, thus affecting the heat dissipation efficiency of the fins.

[0006] This utility model is implemented as follows: a heat-insulated, high-density aluminum busbar trunking includes a mounting base and conductive components. A cover plate is fixed to the top of the mounting base, a cylinder is fixed to the middle of the cover plate, a U-shaped frame is fixed to the output end of the cylinder, and a crossbeam is fixed to the bottom end of each U-shaped frame. Grooves are formed on the sidewalls of the mounting base near the crossbeams, and heat dissipation fins are fixed to the inner sidewalls of the grooves. Wire brushes are fixed to the sidewalls of the crossbeams near the heat dissipation fins. Several slots are formed at both ends of the mounting base. Each conductive component includes a conductive busbar inserted into the slot. Holes are formed on the sidewalls of the mounting base.

[0007] Preferably, the surface of the mounting base is provided with a slot, the internal dimensions of which are adapted to the external dimensions of the cover plate, and two holes are symmetrically provided at the bottom of the inner surface of the slot for bolt connection, which improves the stability of the installation of the conductive components.

[0008] Preferably, the mounting base has a second slot in the middle for the conductive busbar to be inserted. The second slot is connected to the first slot and the first slot in sequence, which facilitates the installation and positioning of the conductive busbar.

[0009] Preferably, a plurality of insulating blocks are fixedly provided at the inner bottom of the second slot, and a plurality of slots are provided at the top of the insulating blocks for the conductive busbar to be engaged, which further improves the stability of the conductive busbar installation.

[0010] Preferably, the outer surface of each conductive busbar is fitted with an insulating sleeve, which is made of cross-linked polyethylene. The external dimensions of the insulating sleeve are adapted to the internal dimensions of slot two and slot one, thereby improving the stability of the conductive busbar installation.

[0011] Preferably, the mounting base is fixed with limiting rods on the side walls near both ends of the crossbeam, and the crossbeam has three holes for the limiting rods to be inserted into. The external dimensions of the limiting rods are adapted to the internal dimensions of the three holes, which improves the stability of the vertical movement of the two ends of the crossbeam.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Please see Figure 1-4 The present invention provides an embodiment of a heat-insulated, high-density aluminum busbar trunking, comprising a mounting base 1 and a conductive component 2. A cover plate 3 is fixed to the top of the mounting base 1. A cylinder 4 is fixed to the middle of the cover plate 3 via bolts. A U-shaped frame 5 is fixed to the output end of the cylinder 4 via a coupling. A crossbeam 9 is welded to the bottom of the U-shaped frame 5 to form an integral structure. Grooves 7 are formed on the sidewalls of the mounting base 1 near the crossbeam 9. Heat dissipation fins 8 are fixed to the inner sidewalls of the grooves 7 via bolts to increase the heat dissipation area and improve heat dissipation efficiency. A wire brush 10 is fixed to the sidewalls of the crossbeam 9 near the heat dissipation fins 8 to clean dust. Several slots 6 are formed at both ends of the mounting base 1. A slot 12 is formed on the surface of the mounting base 1. The internal dimensions of the slot 12 are adapted to the external dimensions of the cover plate 3. The surface of the slot 12... Two symmetrical slots 14 are provided on the bottom of the mounting base for bolt connection, which improves the stability of the installation of the conductive component 2. The middle of the mounting base 1 has a slot 13 for the conductive busbar 201 to be inserted. The slot 13 is connected to the slot 6 and the slot 12 in sequence, which facilitates the installation and positioning of the conductive busbar 201. The side walls of the mounting base 1 are provided with slots 17 for bolt connection. The conductive component 2 includes a conductive busbar 201 inserted into the slot 6. The conductive busbar 201 is made of copper with a large cross-section to improve the current transmission efficiency. When dust adheres to the surface of the heat sink 8 and affects heat dissipation, the operator can start the cylinder 4 to drive the two crossbeams 9 to move vertically, thereby driving the wire brush 10 to clean the dust along the gaps of the heat sink 8, which can improve the heat dissipation efficiency of the heat sink 8 and prevent the conductive busbar 201 from overheating and causing increased energy consumption.

[0022] Several insulating blocks 15 are fixedly installed at the bottom of the second slot 13. Several slots 16 are opened at the top of the insulating blocks 15 for the conductive bus 201 to be engaged, which further improves the stability of the installation of the conductive bus 201. The outer surface of the conductive bus 201 is covered with an insulating sleeve 202. The insulating sleeve 202 is made of cross-linked polyethylene. The external dimensions of the insulating sleeve 202 are adapted to the internal dimensions of the slots 16 and 6, which improves the stability of the installation of the conductive bus 201.

[0023] Limiting rods 11 are fixed on the side walls of both ends of the mounting base 1 near the crossbeam 9. The limiting rods 11 are round rods with smooth surfaces. Both ends of the crossbeam 9 are provided with slots 3 18 for the limiting rods 11 to be inserted. The external dimensions of the limiting rods 11 are adapted to the internal dimensions of the slots 3 18. The limiting rods 11 can restrict the lateral displacement of both ends of the crossbeam 9 and improve the stability of the vertical movement of both ends of the crossbeam 9.

[0024] Working principle: When using this type of heat-insulated, high-density aluminum busbar trunking, the operator first connects an external power supply. The conductive busbar 201 is made of copper with a large cross-section and good conductivity. Both ends of the conductive busbar 201 have threaded holes for connecting insulated bolts to facilitate wiring and conduction. The mounting base 1 and the crossbeam 9 are both made of aluminum alloy. When current flows through the conductive busbar 201, heat is generated, causing the temperature to rise. The crossbeam 9 can increase the contact area between the mounting base 1 and the air, thereby improving the heat dissipation efficiency of the conductive busbar 201 and avoiding increased resistance due to temperature rise, which would lead to energy loss. When dust adheres to the surface of the crossbeam 9 and affects the heat dissipation efficiency, the starting cylinder 4 can drive the two crossbeams 9 to move vertically, thereby facilitating the movement of the wire brush 10 to clean the dust along the gaps in the heat dissipation fins 8, thus improving the heat dissipation efficiency of the heat dissipation fins 8.

[0025] Secondly, the two limiting rods 11 are slidably connected inside the three holes 18 in sequence, thereby limiting the lateral displacement at both ends of the crossbeam 9 and improving the stability of the wire brush 10 when cleaning dust.
