Problems solved by technology

Especially when the power system where the substation is located fails, switching operations, equipment maintenance, and testing, the tubular busbar will have a large current momentary conduction or interruption. At this time, the electromagnetic radiation intensity is high, and the external electromagnetic interference is also greatly affected.

Embodiment Construction

[0023] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the scope of protection of the present invention is not limited to the following Described embodiment.

[0024] Such as figure 1 , 2 As shown, the electromagnetic shielding tubular busbar of the substation according to the present invention includes a tubular busbar body 1 made of copper or aluminum, and iron for electromagnetic shielding is deposited on the outer peripheral surface of the busbar body 1 through an electrolytic deposition process. The composition of the iron-based amorphous alloy layer 2 is Fe: 68.77%, Co: 18.23%, Si: 0.99%, and B: 12.01%. The deposition thickness of the iron-based amorphous alloy layer is determined according to Table 1-3.

Abstract

The invention discloses an electromagnetic shielding type tubular bus of a transformer substation. The tubular bus comprises a tubular bus body, an iron-based amorphous alloy layer used for electromagnetic shielding is deposited on a peripheral surface of the bus body through an electrolytic deposition process, and the iron-based amorphous alloy layer comprises 68.77% of Fe, 18.23% of Co, 0.99% ofSi and 12.01% of B. The tubular bus has the advantages that on the basis of the prior art, the electromagnetic radiation intensity of the tubular bus on the medium-voltage side of a main transformerof the transformer substation is reduced by 50%-70%; the influence of electromagnetic radiation on residents and social personnel outside the transformer substation can be reduced, the influence of electromagnetic radiation on operating personnel inside the transformer substation is reduced, and a good living environment and a good working environment are created.

Description

technical field [0001] The invention relates to a tubular busbar of a transformer lead-out line in a power system substation, in particular to an electromagnetic shielding tubular busbar of a substation. Background technique [0002] Electromagnetic radiation refers to a part of the electromagnetic energy emitted by the field source that is separated from the field source and propagates far away, and the energy diffuses outward in the form of electromagnetic waves. Electromagnetic waves are electric and magnetic fields that move and transfer energy in the form of waves, including radio waves, microwaves, infrared rays, visible light, ultraviolet rays, x-rays, gamma rays, etc. Construction of substations in urban (town) areas, to be precise, there are electric fields, magnetic fields and electromagnetic radiation inside and around the substations; the main reason for the generation of electric fields, magnetic fields and electromagnetic radiation is that the live equipment an...
