Abstract
The utility model relates to a telescopic joint for a gas insulation metal seal combined electrical apparatus, and mainly solves the problem that the traditional telescopic joint cannot absorb axial displacement generated by a bus and basic expansion and contraction. The telescopic joint comprises bellows, flanges, studs and nuts, wherein the diameter of each bellow changes alternately along the axial direction, the flanges are arranged at the end parts of the bellows and the diameter alternating positions, each of the screws is connected between every two adjacent flanges, and the nuts are arranged at the two ends of each stud. As the diameter of each bellow changes alternately along the axial direction, errors generated by installation adjusting can be absorbed, the axial displacement generated by the bus and the basic expansion and contraction can be absorbed, the force born by the studs and the flanges is reduced, and the service lives of the studs and the flanges are prolonged.
Description
Technical field
The utility model relates to a kind of slip joint, and a kind of specifically gas-insulated metal-enclosed combined electrical apparatus is used slip joint.
Background technique
In order to absorb the error that produces because of install adjustment, the relevant position in the gas-insulated metal-enclosed combined electrical apparatus need be installed slip joint.In the actual moving process of equipment; The error that not only exists install adjustment to produce; Also exist because of bus and the basic axial displacement of expanding with heat and contract with cold and producing; Traditional slip joint structure is that isodiametric bellows two ends are provided with the flange formation, and this kind slip joint is merely able to absorb the error that produces because of install adjustment, can not absorb because of bus and the basic axial displacement of expanding with heat and contract with cold and producing.Because the axial displacement that exists bus and basis to expand with heat and contract with cold and produce can make that just flange and double-screw bolt are in stress for a long time, shortened working life like this.
The model utility content
The purpose of the utility model is to provide a kind of gas-insulated metal-enclosed combined electrical apparatus to use slip joint, and this slip joint not only can absorb the error that produces because of install adjustment, can also absorb because of bus and the basic axial displacement of expanding with heat and contract with cold and producing.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of gas-insulated metal-enclosed combined electrical apparatus is used slip joint; Comprise bellows, flange, double-screw bolt and nut; It is characterized in that the size of said bellows diameter is checker vertically, alternately locate to be equipped with flange at the end and the diameter of bellows; Be connected with double-screw bolt between per two adjacent flanges, the two ends of said double-screw bolt are respectively equipped with nut.
Compared with prior art; The utlity model has following outstanding beneficial effect: simple and reasonable, easy to use, the size of bellows diameter is checker vertically; Not only can absorb the error that produces because of install adjustment; Can also absorb because of bus and the basic axial displacement of expanding with heat and contract with cold and producing, reduce the stressed of double-screw bolt and flange, increase its working life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 flange, 2 bellowss, 3 double-screw bolts, 4 nuts.
Embodiment
As shown in Figure 1.A kind of gas-insulated metal-enclosed combined electrical apparatus of the utility model is used slip joint; Comprise bellows 2, flange 1, double-screw bolt 3 and nut 4; The size of said bellows 2 diameters is checker vertically; End and diameter at bellows 2 alternately are equipped with flange 1 in the place, are connected with double-screw bolt 3 between per two adjacent flanges 1, and the two ends of said double-screw bolt 3 are respectively equipped with nut 4.
During use, bellows 2 has elasticity, can stretch within the specific limits, contract and bending, thereby absorb the error that produces because of install adjustment; Simultaneously because the size of bellows 2 diameters checker vertically, can absorb the axial displacement of expanding with heat and contract with cold and producing because of bus and basis, reduced the stressed of double-screw bolt 3 and flange 1, increase its working life.
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 Applicable scope; 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 characteristics of specification, all the other technical characteristicss are those skilled in the art's known technology.
