Abstract
The utility model discloses an improved corrugated pipe of a transformer. The corrugated pipe comprises a corrugated pipe body, an upper end part flange and a lower end part flange, wherein the upper end part flange and the lower end part flange are mounted on the upper end and the lower end of the corrugated pipe body. The corrugated pipe is characterized in that the outer circumferential surface of the upper end part flange is symmetrically provided with a first upper fixing lug and a second upper fixing lug; the outer circumferential surface of the lower end part flange is symmetrically provided with a first lower fixing lug and a second lower fixing lug; the first upper fixing lug and the second upper fixing lug are mutually corresponding to the first lower fixing lug and the second lower fixing lug vertically; a corrugated pipe retracting device is arranged on the first lower fixing lug on the left side of the lower end part flange; and the corrugated pipe retracting device is a hydraulic cylinder. According to the utility model, the stretch and compression of the corrugated pipe can be adjusted through the hydraulic cylinder according to actual requirements, and the problem of the deviation existing between an actual floor height and a standard value of a transformer substation can be solved.
Description
Technical field
The utility model relates to transformer corollary equipment is installed, and specifically, relates to a kind of improved transformer bellows.
Background technology
In short supply along with the development of urban distribution network and land resource, particularly for large size city, cost of land is a part very important in the transformer substation construction expense, in order to reduce transformer station's floor space, economize the land resource, become the mounting structure of two-piece unit formula to be widely adopted just gradually the large-capacity power design of transformer.Two-piece unit formula transformer refers to that transformer body is installed in the transformer chamber of transformer station's Stall, and its radiator part is installed concentratedly at the second floor radiator chamber that is positioned at directly over it, be communicated with main body and radiator by transformer turnover oil pipe, reach the effect of transformer oil circulation cooling.The problem that has deviation in order to solve the actual floor height of transformer station and standard value; generally often between transformer turnover oil pipe and main body, install bellows additional; the performance that can stretch in right amount or compress by bellows; remedy because there are the problem of deviation in the actual floor height of transformer station and standard value; but in practical work process, usually can run into bellows and be difficult to the problem that stretches on demand or compress smoothly.
Summary of the invention
The technical problems to be solved in the utility model is to overcome defects, and a kind of improved transformer bellows is provided, and can realize the purpose that bellows stretches according to actual needs or compresses when mounted.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of improved transformer bellows, comprise the bellows main body and be installed in bellows main body up and down upper end flange and the bottom flange at two ends, it is characterized in that: be symmetrically arranged with on first fixedly on the ear, second fixedly ear on the flange excircle side face of described upper end, be symmetrically arranged with the fixedly fixing ear of ear, second time on the flange excircle side face of described bottom first time, on first fixedly on the ear, second fixedly ear respectively with first time fixedly ear, second time fixedly ear is mutually corresponding up and down; Be positioned at first time of bottom flange left side fixedly ear be provided with the bellows retractor device.
Say further:
Described bellows retractor device is hydraulic cylinder, and the bottom of hydraulic cylinder body is fixed on the fixedly upper surface of ear first time, the top of its piston rod be fixed on upper end flange left side first on fixedly on the bottom surface of ear.
Fixedly vertically be fixed with lead on the ear second time of flange right side, described bottom, flange right side, upper end second on fixedly ear be provided with pilot hole, pilot hole is run through in the upper end of lead.
Owing to adopted technique scheme, the utility model can utilize according to actual needs hydraulic cylinder to regulate stretching or the compression of bellows, thereby there are the problem of deviation in the solution actual floor height of transformer station and standard value.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the side-looking structural representation of upper end flange described in the embodiment of the present utility model.
Embodiment
Embodiment:
A kind of improved transformer bellows as shown in Figure 1, comprises bellows main body 7 and the upper end flange 6 and the bottom flange 2 that are installed in bellows main body two ends about in the of 7.Be symmetrically arranged with on first fixedly on the ear 5, second fixedly ear 8 on flange 6 outer circumference surfaces of described upper end, be symmetrically arranged with on flange 2 outer circumference surfaces of described bottom first time fixedly ear 1, second time fixedly on the ear 10, the first fixedly on the ear 5, second fixedly ear 8 respectively with first time fixedly ear 1, second time fixedly ear 10 is mutually corresponding up and down.Be positioned at first time of bottom flange 2 left sides fixedly ear 1 be provided with the bellows retractor device.
Described bellows retractor device is hydraulic cylinder, and the bottom of hydraulic cylinder body 3 is fixed on the fixedly upper surface of ear 1 first time, the top of its piston rod 4 be fixed on upper end flange 6 left sides first on fixedly on the bottom surface of ear 5.
Fixedly vertically be fixed with lead 9 on the ear 10 second time of flange 2 right sides, described bottom, upper end flange 6 right sides second on fixedly ear 8 be provided with pilot hole 11, as shown in Figure 2.Pilot hole 11 is run through in the upper end of lead 9.The effect of lead 9 is to prevent that the phenomenon of sideslip from appearring in upper end flange 6 by the push-and-pull of hydraulic cylinder the time.
