Abstract
The utility model relates to a three-phase one-tank type metal flange disc insulator which comprises a disc body and connecting pieces, wherein the disc body is formed by epoxy resin in a pouring mode; three groups of metal conductors are arranged in the disc body at equal intervals; a metal flange is arranged at the edge outside the disc body ; and the connecting pieces are uniformly distributed on the metal flange. In the utility model, the metal flange is coated on the periphery of the disc insulator, so that the epoxy resin disc body is effectively protected to resist the impact and the pressure from the outside and the air leakage caused by cracks generated on the surface of the disc body is prevented; and meanwhile, due to the adoption of the metal flange, isoelectric levels among shells can be effectively ensured, the electromagnetic loss and a switching inrush current are reduced, the full-chain multipoint earthing of the metal shells is realized, an excellent electric channel is ensured, and the safety and reliability of operation of equipment are ensured.
Description
Technical field
The utility model relates to and connects high potential parts and earth potential shell in a kind of 110KV of being mainly used in and the above electric equipment, works the disc insulator that supports with insulating effect, a kind of specifically Threephase common-box metal flange disc insulator.
Background technology
It is in the electric equipment of dielectric that disc insulator is mainly used in 110KV and the above electric power system with the sulfur hexafluoride gas; Like gas-insulated metal-enclosed combined electrical apparatus etc.; It mainly acts on is to connect high potential parts and earth potential shell, rises and supports and insulating effect.Existing disc insulator structure is to be formed by epoxy resin and the cast of conductor one, and the inside and the outside of basin body are arcwall face, and basin body is provided with several equally distributed connectors.The mechanical strength of existing disc insulator is lower, and insulating properties is not good, and the basin body of epoxy resin is easy to generate crackle after receiving external force, causes gas leakage.
The utility model content
The purpose of the utility model is to provide a kind of Threephase common-box metal flange disc insulator, and this disc insulator is provided with metal flange, and effectively guard ring epoxy resins basin body, and minimizing electromagnetic consumable and switch shove, and guarantee well-equipped electrical path.
The technical scheme that its technical problem of the utility model solution is taked is: Threephase common-box metal flange disc insulator; The basin body and the connector that comprise poured with epoxy resin; Equidistance is provided with three groups of metallic conductors in the said basin body; It is characterized in that described basin body outer ledge place is provided with metal flange, is evenly distributed with connector on the said metal flange.
The inside and outside wall of said basin body is stairstepping or waveform.
Described connector is that bolt is female.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, pass through at disc insulator periphery clad metal flange, effectively guard ring epoxy resins basin body to resist impact and the pressure that comes from the outside, prevents to cause gas leakage because of the basin body surface cracks.
2, metal flange can effectively guarantee the equipotential between housing, reduces electromagnetic consumable and switch and shoves, and realizes the full chain multipoint earthing of metal shell, guarantees good electrical path, guarantees the safe and reliable of equipment operation.
3, the inside and outside wall of basin body is stairstepping or waveform, can reduce the oneself height of basin body, and under identical creep distance condition, mechanical strength has certain increase; Under the equal height condition, creep distance increases greatly, the corresponding raising of insulation property.
Description of drawings
Fig. 1 is the external structure sketch map of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1 metal flange, 2 basin bodies, 3 metallic conductors.
Embodiment
Do further description below in conjunction with Figure of description 1 and 2 pairs of the utility model of accompanying drawing:
Threephase common-box metal flange disc insulator; The basin body 2 and the connector that comprise poured with epoxy resin; Equidistance is provided with three groups of metallic conductors 3 in the said basin body 2, and described basin body 2 outer ledge places are provided with metal flange 1, are evenly distributed with connector on the said metal flange 1.
The inside and outside wall of said basin body 2 is stairstepping or waveform.This kind structure can reduce the oneself height of basin body 2, and under identical creep distance condition, mechanical strength has certain increase; Under the equal height condition, creep distance increases greatly, the corresponding raising of insulation property.
Described connector is that bolt is female.
During use, because at basin body 2 periphery clad metal flanges 1, effectively guard ring epoxy resins basin body 2 to resist impact and the pressure that comes from the outside, prevents to cause gas leakage because of basin body 2 surfaces crack; Metal flange 1 can effectively guarantee the equipotential between housing simultaneously, reduces electromagnetic consumable and switch and shoves, and realizes the full chain multipoint earthing of metal shell, guarantees good electrical path, guarantees the safe and reliable of equipment operation.
The above; Some principles of the utility model just explain through diagrams; This specification be not be to the utility model be confined to shown in described concrete structure and the scope of application; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Except that the said technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
