Abstract
The utility model discloses an air insulation extension sleeve pipe, including the casing main body, the casing main body is inside to be equipped with the red copper contact, and red copper contact lower extreme is equipped with the tower and connects the tapering, be equipped with sealed tapering on the casing main body inner wall, the inside embedding of casing main body has the brass inserts, the seal groove has been seted up to the casing main body tail end, be equipped with the creep distance cluster parachute on the casing main body outer wall, creep distance cluster parachute and casing main body formula structure as an organic whole. The utility model discloses simple structure, reasonable in design has increased the creep distance cluster parachute on current sheathed tube basis for accord with 12kv electric pressure standard to ground creepage distance, thereby can use safely in physically at the air insulated cabinets body and solid insulated cabinets, the developing direction of catering to market.
Description
Technical field
The utility model relates to field of transmission equipment, specifically a kind of air insulation expansion sleeve pipe.
Background technology
Existing air insulation expansion sleeve pipe does not meet creepage distance over the ground and meets 12kv voltage class standard, cannot use, can not meet user demand in air insulation cabinet and solid insulation cabinet.
Utility model content
The purpose of this utility model is to provide a kind of air insulation to expand sleeve pipe, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of air insulation expansion sleeve pipe, comprise casing main body, described casing main body inside is provided with red copper contact, and red copper contact lower end is provided with tower and connects tapering; Casing main body inwall is provided with sealing tapering; Casing main body inside is embedded with brass inserts; Casing main body tail end offers seal groove; Casing main body outer wall is provided with creep distance cluster parachute, and creep distance cluster parachute and casing main body are integral type structure.
As further program of the utility model: described casing main body is epoxy resin material.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the basis of existing sleeve pipe adds creep distance cluster parachute, creepage distance is over the ground made to meet 12kv voltage class standard, thus can use safely in air insulation cabinet and solid insulation cabinet, cater to the developing direction in market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-casing main body, 2-creep distance cluster parachute, 3-seal groove, 4-seals tapering, and 5-tower connects tapering, 6-brass inserts, 7-red copper contact.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of air insulation expansion sleeve pipe, comprise casing main body 1, described casing main body 1 inside is provided with red copper contact 7, and red copper contact 7 lower end is provided with tower and connects tapering 5; Casing main body 1 inwall is provided with sealing tapering 4; Casing main body 1 inside is embedded with brass inserts 6; Casing main body 1 tail end offers seal groove 3; Casing main body 1 outer wall is provided with creep distance cluster parachute 2, and creep distance cluster parachute 2 and casing main body 1 are integral type structure.
Further, casing main body 1 described in the utility model is epoxy resin material.
The utility model adds creep distance cluster parachute 2 on the basis of existing sleeve pipe, makes creepage distance over the ground meet 12kv voltage class standard, thus can use safely in air insulation cabinet and solid insulation cabinet, caters to the developing direction in market.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
