Abstract
The utility model discloses a disc spring sleeve corrugated pipe compensator comprising a corrugated pipe as well as an upper flange and a lower flange which are fixed at two ends of the corrugated pipe; the disc spring sleeve corrugated pipe compensator is characterized in that a group of pull rods with sleeves and elastic elements are connected between the upper flange and the lower flange at two ends of the corrugated pipe, the lower ends of the pull rods are fixed on the lower flange of the corrugated pipe, and sleeves at the upper ends of the pull rods are connected with the upper flange of the corrugated pipe by a sleeve cap, and the pull rod at the lower end of the sleeve is further provided with an axial limit nut. The compensator can not only realize position compensation and seal of a fully-closed combined electrical apparatus, but also balance the thrust generated by internal pressure, thus meeting the thrust requirements for fixing a support, and eliminating the safety potential hazard of operation.
Description
Technical field
The utility model relates to a kind of compensator, and a kind of corrugated pipe compensator of disc spring sleeve of saying so more specifically is applicable to the position compensation and the sealing of the gas-insulating and fully-enclosed combined electrical apparatus of SF6 (GIS).
Background technique
What at present, high voltage totally-enclosed combined electrical apparatus (GIS) was a large amount of is applied in modern electric production and the transporting system.Along with the Chinese society rapid economy development, electricity need load constantly increases, and is also more and more higher to the requirement of power supply reliability.High voltage totally-enclosed combined electrical apparatus is safe and reliable to operation, easy for installation owing to having, and has become the leading equipment in the secondary distribution system.Compensator in the fully closed combined electric unit is position compensation and the air locking that is used for fully closed combined electric unit, because of its inner filling has SF6 gas as insulating medium, fixed bearing can't bear bigger thrust, and be operated under the high electric field environment, so require compensator to have to cut down output in the balance ability of living thrust, the living thrust of cutting down output in can not balance that at present on the combined electrical apparatus there be used compensator, press thrust in the energy balance that has, but volume is bigger, cost is higher, has stayed hidden danger for the safe operation of fully closed combined electric unit.
Summary of the invention
The purpose of this utility model provides a kind of corrugated pipe compensator of disc spring sleeve, it not only can realize the position compensation and the sealing of fully closed combined electric unit, and the living thrust of cutting down output in can balance media, thereby satisfy the thrust requirement of fixed bearing, eliminated the potential safety hazard of operation.
The purpose of this utility model is to realize like this, it includes bellows and is fixed on the last lower flange at bellows two ends, it is characterized in that being connected with one group of pull bar that has sleeve and elastic element on the bellows two ends between the lower flange, the lower end of pull bar is fixed on the lower flange of bellows, the sleeve of pull bar upper end is connected with the bellows upper flanges by the tube cap, also is provided with the axial limiting nut on the pull bar of sleeve lower end.
The utility model has the advantages that, owing to be connected with one group of pull bar that has sleeve and elastic element between the last lower flange at bellows two ends, make bellows produce pretension and can offset the thrust that the combined electrical apparatus internal pressure causes, to keep compensator end face stress balance, alleviated the thrust that fixed bearing bears, again because compensator has only increased by one group of elastic draw bar on two end flange of bellows, so compact structure, volume is little, reduced and taken up room, having eliminated the potential safety hazard of fully closed combined electric unit operation, is a kind of novelty and the corrugated pipe compensator of disc spring sleeve product that shows unique characteristics.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a concrete structure cut-away section schematic representation of the present utility model.
Fig. 2 is the edge face structure schematic representation of compensator
Description of reference numerals: 1, tube cap; 2, ball ring; 3, spherical washer; 4, upper flange; 5, sleeve; 6, dish spring; 7, pull bar; 8, bellows; 9, stop nut; 10, tightening nut; 11, lower flange.
Embodiment
In Fig. 1-2, the two ends of bellows 8 are welded with lower flange 4,11 respectively, and the attachment hole that is used for fixing elastic draw bar of one group of corresponding up and down four or more is arranged on last lower flange 4,11.Telescopic elastic draw bar is assembled into by tube cap 1, sleeve 5, dish spring 6, pull bar 7 and stop nut 9.There is the annular stopper in tube the lower end of sleeve 5, and its upper end is provided with the outside thread that cooperates with tube cap 1.Elastic element is that 6, one groups of dish springs 6 of dish spring place on the seam that is stuck in sleeve 5 bottoms in the sleeve 5, and pull bar 7 is screw shaped, and the upper end of pull bar 7 is provided with the annular boss that is used for clamping dish spring 6, and the lower end of pull bar 7 is provided with and is used for the screw thread that cooperates with tightening nut 10.Pull bar 7 is inserted in the endoporus that passes dish spring 6 in the sleeve 5 and passes from the lower end of sleeve 5, tube cap 1 is threaded in the upper end of sleeve 5, stop nut 9 is threaded with pull bar 7 in the lower end of sleeve 5, and sleeve 5, dish spring 6 and pull bar 7 are fixed into one, forms a telescopic flexible pull bar.After the elastic draw bar of four scalable band tube caps 1 adds and prevents a cap 1 loosening ball ring 2 and spherical washer 3, pass the attachment hole on the lower flange 4,11 respectively successively, be fixed on the lower flange 11 of compensator by the lower end of two tightening nuts 10 with elastic draw bar, the sleeve 5 of the elastic draw bar the other end utilizes tube cap 1 to be assembled on the upper flanges 4.One group has the elastic draw bar of sleeve 5 and dish spring 6 or is more than four.
During work, the designing requirement according to fully closed combined electric unit SF6 insulating gas pressure calculates the living thrust of cutting down output in the combined electrical apparatus, selects four or more elastic draw bar, the thrust that the pretension sum that each elastic draw bar is produced equals to calculate.The stop nut of adjusting on the pull bar 79 makes it to be in the position that pretension equates with thrust on pull bar 7.Combined electrical apparatus when work, unclamp stop nut 9, bellows 8 is compensating when mobile, and the elastic force of pull bar 7 is also adjusted thereupon synchronously, keeps compensator end face stress balance, alleviates the thrust that its fixed bearing bears, and increases the service life.
