Utility model content
The utility model object is: for the problems referred to above, a kind of novel expansion sleeve pipe is provided, the insulation property that this expansion sleeve pipe can meet in air insulation cabinet require and creepage distance requirement, itself and existing A-link expand sleeve pipe with the use of time, can be used for the connection of gas-insulated cabinet and air insulation cabinet.
The technical solution of the utility model is: a kind of expansion sleeve pipe, be made up of inner conductive bar and the insulating coating be arranged on outside this inner conductive bar, this expansion sleeve pipe has link in the outer link of the cabinet that is connected with extraneous gas insulation cabinet and the cabinet that is connected with air insulation cabinet internal wiring, described insulating coating forms and is positioned at described cabinet link place, and the annular isolation cover wrapped in outside described inner conductive bar, and this annular isolation puts and offers one and be convenient to circuit in connecting cabinet and the gap that can increase insulation property between two-phase, the outer wall of described insulating coating forms the annular shirt rim be trapped among around it.
The utility model, on the basis of technique scheme, also comprises following optimal technical scheme:
Described annular shirt rim has three, and the axially spaced-apart distribution on the outer wall of described insulating coating of these three annular shirt rims.
Described annular shirt rim has three.
The material of described insulating coating is epoxy resin or glass fibre reinforced nylon.
The utility model has the advantages that: this expansion sleeve pipe of the utility model can meet the requirement of insulation property requirement and creepage distance in air insulation, its can with existing A-link expand sleeve pipe with the use of, to be used for connecting gas-insulated cabinet and air insulation cabinet, its production cost is low, and environmental protection is without SF6.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the perspective view of this expansion sleeve pipe of the utility model;
Fig. 2 is the axial cutaway view of this expansion of the utility model sleeve pipe;
Fig. 3 is the axial side view of this expansion sleeve pipe of the utility model;
Fig. 4 is the practical application figure of this expansion sleeve pipe of the utility model;
Wherein: 1-inner conductive bar, 2-insulating coating, 2a-annular isolation cover, 2b-annular shirt rim, the outer link of 3-cabinet, link in 4-cabinet, 5-gap, 6-A-link expands sleeve pipe, 7-gas-insulated cabinet, 8-air insulation cabinet, 9-first mounting panel, 10-second mounting panel, 11-A-link connector.
Embodiment
Fig. 1 ~ Fig. 4 illustrates a specific embodiment of this expansion sleeve pipe of the utility model, this expansion sleeve pipe when practical application, need with existing A-link expand sleeve pipe 6 with the use of, thus gas-insulated cabinet 7 and air insulation cabinet 8 to be coupled together.
What this expansion of the present embodiment sleeve pipe was identical with common expansion sleeve pipe is, it is also be made up of inner conductive bar 1 and the insulating coating 2 be arranged on outside this inner conductive bar 1, and this expansion sleeve pipe has link 4 in the outer link 3 of the cabinet that is connected with extraneous gas insulation cabinet and the cabinet that is connected with air insulation cabinet internal wiring.
The key improvements of the present embodiment is: described insulating coating 2 forms be positioned at described cabinet link 3 place and the annular isolation cover 2a wrapped in outside described inner conductive bar 1, this annular isolation cover 2a offers one and is convenient to circuit in connecting cabinet and the gap 5 increasing insulation property between two-phase.This annular isolation cover 2a adds the structural design of gap 5, the insulation property between adjacent two phase conductors can be made to strengthen, enable this expansion sleeve pipe meet the instructions for use in air insulation.
In addition, this example forms three annular shirt rim 2b spaced apart on the outer wall of described insulating coating 2, and these three annular shirt rim 2b axially spaced-apart distribution on the outer wall of insulating coating 2.The annular shirt rim 2b that insulating coating 2 is arranged adds the creepage distance of conductor and side, enables this expansion sleeve pipe meet gas isolated instructions for use.Certainly, the quantity of described annular shirt rim 2b is not limited to three, also can be one, two, five etc.
The material of described insulating coating 2 can adopt epoxy resin, also can adopt glass fibre reinforced nylon.
The concrete occupation mode of this expansion of the present embodiment sleeve pipe can refer to shown in Fig. 4: first utilize the first mounting panel 9 A-link to be expanded sleeve pipe 6 and be fixed in gas-insulated cabinet 7, and then utilize the second mounting panel 10 this for the utility model expansion sleeve pipe to be fixed on (the outer link 3 of cabinet of this sleeve pipe cooperatively interacts with described second mounting panel 10 thus is fixed in air insulation cabinet by this expansion sleeve pipe) in air insulation cabinet 8, A-link connector 11 (this A-link connector is conductor) is utilized A-link to be expanded sleeve pipe 6 afterwards and this expansion sleeve pipe of the utility model connects together, A-link expands sleeve pipe 6 and is connected with circuit in the cabinet in gas-insulated cabinet 7, this expansion sleeve pipe of the utility model (in cabinet link 4) is connected with circuit in the cabinet in air insulation cabinet 8, thus achieve the connection of gas-insulated cabinet 7 and air insulation cabinet 8.The gap 5 that annular isolation cover 2a offers not only facilitates the connection of circuit and this expansion sleeve pipe in air insulation cabinet 8 cabinet, the positional stability of this opening position circuit can also be ensured, avoid the exhaust position of this place's circuit to offset, also there is the function increasing insulation property between two-phase simultaneously.
Be not difficult to find out, after installation, most of structure of this expansion sleeve pipe is all in air insulation cabinet 8, and in its cabinet, link 4 is connected with circuit in the cabinet in air insulation cabinet 8, and the outer link 3 of cabinet is connected with the gas-insulated cabinet 7 of outside.
Above-mentioned A-link connector 11 and A-link expand sleeve pipe 6 and are existing product.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection range of the present utility model.
