Abstract
The utility model relates to an oil chamber with an on-load tap switch, comprising an insulating cylinder and a cylinder bottom, wherein, the insulating cylinder is integrated with the cylinder bottom. The utility model is characterized in that the inner wall of the insulating cylinder in a circumferential direction is provided with 9 longitudinal reinforcing ribs whose 3 cross sections are respectively provided with a groove, totally 3 rings of grooves. The oil chamber with simple structure can reduce the deposition of the insulating oil pollutant to improve the insulating performance.
Description
The utility model relates to a kind of grease chamber that is used on load tap changer.
On load tap changer is used for the transformer voltage-regulating system, at transformer year tap position of state change transformer, the voltage of rising or reduction step down side is arranged.The structure of on load tap changer comprises grease chamber, trigger device, spring energy agency and motor decelerating mechanism.Wherein the grease chamber is made up of insulating cylinder, the tube end and sealing ring, and insulating cylinder is screwed with the tube end and is connected, and the junction is provided with sealing ring, and the insulating cylinder inwall is provided with three circle grooves, is used to install fixed contact.In the course of the work, the pollutant that insulating oil produces is deposited in the insulating cylinder inboard wall groove easily, thereby reduces the insulation property of grease chamber, influences the operation of on load tap changer.
The purpose of this utility model provides a kind of simple in structure, and can reduce the deposition of insulating oil pollutant, keeps the grease chamber of good insulation performance.
The grease chamber that the utility model proposes was made up of the insulating cylinder and the tube end, insulating cylinder was integrated with the tube end, it is characterized in that the insulating cylinder inwall along the circumferential direction is provided with 9 walings, on three cross sections of 9 reinforcements, offer groove respectively, offer 3 circle grooves altogether.
The grease chamber that the utility model proposes is simple in structure, and insulating cylinder was integrated with the tube end, can adopt the engineering plastics compression molding, had omitted the sealing ring of tube bottom.In addition, the groove that is used to install fixed contact is opened in 9 reinforcements of insulating cylinder inwall, rather than be opened on the whole circumference of insulating cylinder inwall, no longer be provided with groove on the insulating cylinder inwall between each tap fixed contact, avoided the deposition of the pollutant in the insulating oil, thereby improved the insulation property of grease chamber at this position.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is further described.
Shown in Figure 1 is the overall structure figure that adopts the on load tap changer of this grease chamber;
Shown in Figure 2 is the cutaway view of this grease chamber;
Shown in Figure 3 is the vertical view of this grease chamber.
The grease chamber that the utility model proposes (1) is made up of insulating cylinder (2) and the tube end (5), and insulating cylinder (2) is integrated with the tube end (5), adopts the engineering plastics mold pressing to make.In addition, insulating cylinder (2) inwall along the circumferential direction is provided with 9 walings (3), offers groove (4) respectively on 3 cross sections of 9 walings (3), offers 3 circle grooves (4) altogether, and 3 27 grooves of circle (4) are used to install fixed contact.
