Description

Technical Field

[0001] The utility model belongs to the technical field of intensive bus ducts, and in particular relates to a fireproof intensive bus duct. Background Art

[0002] The intensive bus duct is a busbar system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive bars, insulating materials and related accessories. The intensive bus duct has the characteristics of large current capacity and good quality and safety performance.

[0003] Existing dense bus ducts are difficult to handle well in terms of fire protection. Most of them are only protected by a single fire-retardant coating. At the same time, the main cause of bus duct fire is poor internal heat dissipation function, which easily causes fire and copper busbar short circuit.

[0004] Therefore, a fire-resistant intensive bus duct is proposed. Utility Model Content

[0010] Preferably, there are two protective plates in total, and the two protective plates are symmetrically arranged on the outer side wall of the dense bus duct shell.

[0011] Preferably, a through groove that precisely matches the conductive copper busbar is opened on one side outer wall of the shell cover.

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

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

[0021] The present invention provides a fire-resistant intensive bus duct. Figure 1-4 As shown, it includes a dense bus duct shell 1, a protective plate 2 is fixedly connected to the outer wall of the dense bus duct shell 1 by bolts, and there are two protective plates 2, and the two protective plates 2 are symmetrically arranged on the outer wall of the dense bus duct shell 1, and a shell cover 3 is fixedly connected to the inner wall of the dense bus duct shell 1 by bolts. A conductive copper busbar 4 is arranged inside the dense bus duct shell 1, and a through groove that precisely matches the conductive copper busbar 4 is opened on one side of the outer wall of the shell cover 3. The dense bus duct shell 1 is adjacent to the outer side of the protective plate 2. A heat dissipation hole 5 is opened on the wall, and the inner wall of the dense bus duct shell 1 is covered with a fireproof filling layer 6, and a fire-retardant ring 7 is embedded on the outer wall of one side of the fireproof filling layer 6. The interior of the dense bus duct shell 1 and the protective plate 2 are penetrated by a heat dissipation pipe 8 and an inlet and outlet pipe 9. The heat dissipation pipe 8 is located on one side of the inlet and outlet pipe 9. A heat dissipation guide ring 10 is provided at one end of the inlet and outlet pipe 9 near the internal position of the dense bus duct shell 1. The heat dissipation guide ring 10 is connected to the inlet and outlet pipe 9, and one end of the heat dissipation pipe 8 and the inlet and outlet pipe 9 protrude from the protective plate 2.

[0022] It should be noted that, since the existing dense bus duct is difficult to handle well in terms of fire prevention, most of them are only fireproofed by a single fire-retardant coating. At the same time, the main cause of bus duct fire is the poor internal heat dissipation function, which is prone to fire and causes copper busbar short circuit. This embodiment guides the air through the interior of the dense bus duct shell 1 and uses the fire-retardant ring 7 to fire-retard the air entry channel, effectively bringing out the heat in the dense bus duct shell 1, realizing the heat dissipation inside the dense bus duct shell 1, ensuring that the dense bus duct shell 1 has fire prevention capabilities while having effective heat dissipation capabilities, avoiding fires caused by excessive temperatures inside the dense bus duct shell 1.

[0023] Specifically, in this embodiment, this scheme mainly includes a through heat dissipation hole 5, a fire retardant ring 7, a heat dissipation pipe 8, an inlet and outlet pipe 9 and a heat dissipation guide ring 10. When the dense bus duct shell 1 and its interior are dissipating heat, air can enter the through heat dissipation hole 5. The linear structure of the through heat dissipation hole 5 can make the air flow in a convection manner inside the through heat dissipation hole 5. The air is in full contact with the dense bus duct shell 1, thereby achieving effective heat dissipation of the dense bus duct shell 1. The air enters the heat dissipation pipe 8 and the inlet and outlet pipe 9, and the inlet and outlet pipe 9 guides the air to the heat dissipation guide ring 10. Since the heat dissipation pipe 8 and the heat dissipation guide ring 10 pass through the dense bus duct shell 1, the air flows through the interior of the dense bus duct shell 1, and the air contacts the heat inside the dense bus duct shell 1 and exchanges heat. The heat in the dense bus duct shell 1 is brought out, thereby achieving heat dissipation inside the dense bus duct shell 1, ensuring that the dense bus duct shell 1 has fire protection capabilities while having effective heat dissipation capabilities, thereby avoiding fire caused by excessive temperature inside the dense bus duct shell 1.

[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the cross sections of the dense bus duct housing 1 and the fireproof filling layer 6 are both rectangular frame structures.

[0025] In this embodiment, the rectangular frame-type dense bus duct housing 1 and the fireproof filling layer 6 provide protection for the conductive copper busbar 4 on the one hand, and play a role in fire protection for the conductive copper busbar 4 on the other hand.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the fire-retardant ring 7 is sleeved on the outer side walls of the heat dissipation conduit 8 and the inlet and outlet pipes 9.

[0027] In this embodiment, the heat dissipation conduit 8 and the inlet and outlet pipes 9 can be fire-proofed and flame-retarded by the fire-retardant ring 7. The fire-retardant expansion core material is filled in the fire-retardant ring 7. When a fire occurs, the flame-retardant expansion core material expands rapidly due to heat, and the expansion is squeezed inside the heat dissipation conduit 8 and the inlet and outlet pipes 9, thereby sealing the pipe penetration hole in a relatively short time and preventing the fire from spreading along the hole.
