[0002] A busbar refers to a product made of high-conductivity copper or aluminum materials for transmitting electric energy, with the ability to collect and distribute electric power. It is the main conductor for transmitting electric energy in a power station or substation. Through it, the electric energy output from a generator, transformer, or rectifier is transmitted to each user or other substations. Most of the connections between various voltage distribution devices in a substation, as well as the connections between electrical equipment such as transformers and corresponding distribution devices, use bare conductors or stranded wires with rectangular or circular cross-sections.

In view of this, the utility model proposes a composite shielded insulated pipe busbar. Content of the Utility Model

[0012] Preferably, the anti-aging layer is made of polyethylene.

[0013] Preferably, the reinforcing sleeve is made of aluminum alloy.

[0014] Preferably, the fireproof paint completely wraps the surface of the outer layer.

[0015] The working principle and beneficial effects of the present utility model are as follows:

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] A preferred embodiment of a composite shielded insulated tubular busbar provided by the present invention is as Figures 1 to 4 shown: A composite shielded insulated tubular busbar includes a conductor 1, a shielding layer 2 is tightly wrapped on the surface of the conductor 1, an insulating layer 3 is tightly wrapped on the surface of the shielding layer 2, a wrapping layer 4 is tightly wrapped on the surface of the insulating layer 3, an aluminum foil paper layer 5 is wound around the surface of the wrapping layer 4, a groove 6 is provided on one side of the surface of the wrapping layer 4 where the aluminum foil paper layer 5 is located, and an enameled wire 7 is wound inside the groove 6.

[0027] In this embodiment, the conductor 1 is made of purple copper. Since the conductor 1 is made of purple copper and purple copper has good electrical conductivity, when in use, purple copper can reduce the additional power consumption.

[0028] In this embodiment, the shielding layer 2 is a composite fiber mesh. The shielding layer 2 completely wraps the surface of the conductor 1. By setting the shielding layer 2 as a composite fiber mesh, the shielding layer 2 is made by resin finishing the fabric with an antistatic agent and adhering it to the surface of the synthetic fiber fabric through padding and baking, which can protect the inside of the insulated tubular busbar and make the inside of the insulated tubular busbar not affected by the external electric field.

[0029] In this embodiment, the insulating layer 3 is made of rubber. By setting the insulating layer 3 made of rubber, an insulating effect can be achieved to avoid leakage of the busbar.

[0030] In this embodiment, the wrapping layer 4 is made of graphene, and the aluminum foil paper layer 5 is wound around the surface of the wrapping layer 4 at equal intervals in a spiral shape. By setting the aluminum foil paper layer 5, the performance of the shielding layer 2 against external electromagnetic interference can be further improved.

[0031] In this embodiment, the enameled wire 7 is completely hidden inside the groove 6, and the width of the enameled wire 7 is smaller than that of the groove 6. Since the enameled wire 7 does not fit with the groove 6, the gap between the two can well diffuse the internal heat.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, a preferred embodiment of a composite shielded insulated tubular busbar provided by the present invention is as Figures 1 to 4As shown: The surface of the aluminum foil layer 5 is tightly wrapped with an anti-aging layer 8, the surface of the anti-aging layer 8 is tightly wrapped with a reinforcement sleeve 9, the surface of the reinforcement sleeve 9 is tightly wrapped with an outer layer 10, and the surface of the outer layer 10 is coated with fireproof paint 11.

[0034] In this embodiment, the anti-aging layer 8 is made of polyethylene. By setting the anti-aging layer 8 made of polyethylene, it can avoid self-aging and prevent the lack of protection for internal components.

[0035] In this embodiment, the reinforcement sleeve 9 is made of aluminum alloy. The reinforcement sleeve 9 has good scratch resistance, which can enhance the protection of the busbar and avoid the problem that when the outer layer 10 is scratched, the reinforcement sleeve 9 is also damaged, exposing the internal components to the outside.

[0036] In this embodiment, the fireproof paint 11 completely wraps the surface of the outer layer 10. By setting the fireproof paint 11 coated on the surface of the outer layer 10, it can achieve good fireproof performance.

[0037] The working principle and usage process of the present utility model: First, since the conductor 1 is made of red copper, and red copper has good electrical conductivity, during use, red copper can reduce the additional power consumption. By setting the shielding layer 2 which is a composite fiber mesh, the shielding layer 2 is made by resin finishing the fabric with an antistatic agent, and then adhered to the surface of the synthetic fiber fabric through padding and baking, which can protect the inside of the insulated tubular busbar and prevent the inside of the insulated tubular busbar from being affected by the external electric field. By setting the insulating layer 3 made of rubber material, it can achieve an insulating effect and avoid electric leakage of the busbar. By setting the aluminum foil layer 5, it can further improve the performance of the shielding layer 2 in resisting external electromagnetic interference. Since the enameled wire 7 and the groove 6 do not fit together, the gap between them can well dissipate the internal heat.

[0038] By setting the anti-aging layer 8 made of polyethylene, it can avoid self-aging and prevent the lack of protection for internal components. By setting the reinforcement sleeve 9 with good scratch resistance, it can enhance the protection of the busbar and avoid the problem that when the outer layer 10 is scratched, the reinforcement sleeve 9 is also damaged, exposing the internal components to the outside. And by setting the fireproof paint 11 coated on the surface of the outer layer 10, it can achieve good fireproof performance.
