Description
Technical Field
The utility model relates to a vacuum has the tapping switch field, specifically is a novel middle insulator tube structure for having tapping switch.
Background
The on-load tap-changer is a switching device for providing constant voltage for a transformer when the load changes, and the basic principle is to realize the switching between taps in the winding of the transformer under the condition of ensuring that the load current is not interrupted, thereby changing the number of turns of the winding, namely the voltage ratio of the transformer, and finally realizing the purpose of voltage regulation.
The traditional upper and lower metal methods mostly adopt cast processing and molding, the processing allowance is large, and the production cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an insulating cylinder structure in middle of novel for having load tap-changer adopts whole aluminum plate one-time stamping forming, and for traditional mechanical metal cutting, its manufacturing cost is lower. Meanwhile, the integrally stamped metal flange is adopted, the surface of the metal flange is smooth and flat, and the generation of partial discharge can be effectively prevented.
The technical scheme of the utility model:
the utility model provides a novel middle insulator cylinder structure for on-load tap-changer, includes the insulator cylinder, installs metal flange at the top of insulator cylinder, installs down metal flange at the lower extreme of insulator cylinder, goes up metal flange and passes through bolt fixed mounting on the insulator cylinder with lower metal flange, installs the shielding cap in bolt department.
The upper metal flange is connected with a mounting flange on the tapping switch oil chamber, and the lower metal flange is connected with the lower end of the switching part of the tapping switch, so that the switching switch is integrally mounted in the tapping switch oil chamber.
The bolt penetrates from the outer side wall to the inner side wall of the insulating cylinder, and the shielding caps are installed at two ends of the bolt.
The bolts are equally spaced to form a circle around the side wall of the insulating cylinder to fix the upper metal flange and the lower metal flange.
The upper metal flange and the lower metal flange are formed by punching the whole aluminum plate at one time.
Compared with the prior art, the beneficial effects of the utility model are that: and the integral aluminum plate is punched and formed at one time, so that the production cost is lower compared with the traditional mechanical metal cutting processing. Meanwhile, the integrally stamped metal flange is adopted, the surface of the metal flange is smooth and flat, and the generation of partial discharge can be effectively prevented.
