Technical field
GIS bus and GIL equipment electric power is inhibited to damage using high permeability material coated conductor the present invention relates to a kind of
Method.
Background technique
GIS (gas insulation metal seal combined electrical apparatus) and GIL (gas-insulated metal closed power transmission line) is to use
High voltage, the high current power transmission device of SF6 or other gas-insulateds, shell and conductor coaxial arrangement.GIS and GIL at present
Shell generallys use aluminum alloy materials, no magnetic field shielding, and the current-carrying conductor of GIS and GIL are due to by neighbouring stable state and transient state electricity
The raw magnetic fields of miscarriage incude Lorentz force and vibrate, and this vibration is to cause disc insulator, supporting insulator, electrical connection
The major reason of contact failure.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a kind of using high permeability material coating
The method that conductor inhibits GIS bus and the damage of GIL equipment electric power.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
GIS bus and the damage of GIL equipment electric power are inhibited using high permeability material coated conductor the invention discloses a kind of
Method comprising following steps:
S1, using high magnetic magnetic conduction coating, plating, the conductive surface coated in GIS bus and GIL, being formed has magnetic field
The magnetic masking layer of shielding action is covered by high magnetic conduction coating and forms magnetic masking layer on conductor, and current-carrying conductor is held in reduction
The magnetic field that suffered proximity conductor electric current generates influences, and reduces the electromagnetic force that equipment power frequency and fault current generate conductor.
The beneficial effects obtained by the present invention are as follows being:
The GIS bus of aluminum alloy casing and GIL electric power is inhibited to damage using high magnetic conduction coating the present invention provides a kind of
Method, by high magnetic permeability magnetic material plating, the conductive surface coated in GIS bus and GIL, being formed has magnetic field shielding effect
Magnetic masking layer, pass through magnetic masking layer and reduce external magnetic suffered by GIS bus and GIL local current carrying conductor using aluminum alloy casing

Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As shown in Figure 1, a kind of inhibit GIS bus and GIL equipment electric power to damage using high permeability material coated conductor
Method comprising following steps:
S1, using high magnetic magnetic conduction coating, plating, the conductive surface coated in GIS bus and GIL, being formed has magnetic field
The magnetic masking layer of shielding action is covered by high magnetic conduction coating and forms magnetic masking layer on conductor, and current-carrying conductor is held in reduction
The magnetic field that suffered proximity conductor electric current generates influences, and reduces the electromagnetic force that equipment power frequency and fault current generate conductor.
1. shielding mode design conditions
External magnetic field is reduced to reduce short-circuit electromotive force using the scheme of conductor coating shielding material, calculates the conductor of each phase
Electric power.It applies overlap layer and Ci coating complete cycle coated conductor is led using height.
| Title material | Gao Dao Ci coating |
| Relativepermeabilityμr=μ/μ 0 | 7000~10000 |
2. magnetic field shielding effect calculated result
By taking the B phase calculated result of GIL as an example, after GIL installs two kinds of Shielding plans additional, magnetic field is greatly decreased in B phase shell,
Conductor magnetic field greatest around by 6509uT drops to 1500uT hereinafter, fall is up to 76% or more.
3. electric power calculated result
GIL three-phase electricity dynamic contrast when unshielded and use complete cycle package Shielding plan
| Shielding mode | Without exterior shield | Complete cycle package shielding |
| Run stable state electric power N/m | 14.3 | 4.6 |
| Three-phase shortcircuit transient state electric power N/m | 413.21 | 94.7 |
By taking the B phase calculated result of GIL as an example, after GIL installs two kinds of Shielding plans additional, electric power suffered by B phase conductor is substantially
It reduces, operation stable state electric power fall is up to 65% or more, and three-phase shortcircuit transient state electric power fall is up to 73% or more.
Theoretical calculation shows in the way of additional high permeability material, is significantly reduced the generation of proximity conductor suffered by conductor
Magnetic field influence, be greatly decreased the electromagnetic force that power frequency and fault current generate conductor, reduce inside disc insulator and support
Damage of the insulator by electric power constant impingement, promotes service life and the dielectric behavior of insulating part, and then the fortune of GIL is substantially improved
Row reliability.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
