Abstract
The utility model provides a switching supporting cylinder assembly of an on-load tap-changer, which comprises an upper supporting plate, a lower supporting plate and a supporting cylinder which is connected between the upper and the lower supporting plates, wherein the periphery of the lower supporting plate is provided with a plurality of mounting plates and a plurality of connecting plates; the supporting cylinder comprises a supporting cylinder body and a connecting ring which is arranged on the lower part of the supporting cylinder body, the connecting ring is provided with a plurality of notches which are matched with the mounting plate on the lower supporting plate and a plurality of connecting holes which are matched with the connecting plate on the lower supporting plate, the lower end of the supporting cylinder is inserted and embedded with the lower supporting plate through the connecting ring, and thus, the lower end of the supporting cylinder is connected with the lower supporting plate as an integral body. The switching supporting cylinder assembly of the on-load tap-changer of the utility model has the advantages of simple structure and reliable connection, and because the outer diameter of the lower end of the supporting cylinder body is enlarged to make into the connecting ring, the connecting ring is directly and rigidly connected with the lower supporting plate.
Description
Technical field
The utility model relates to a kind of electric equipment, particularly a kind of switching support tube assembly of on load tap changer.
Background technology
The switching support tube assembly of on load tap changer is one of parts of forming the on load tap changer switch core, and two other parts that are used for being fastenedly connected the on load tap changer switch core are stored energy mechanism and switching mechanism, and bear the voltage to earth of switch.The primary structure of on load tap changer switch core comprises and switches support tube assembly 11, stored energy mechanism 12 and switching mechanism 13 as shown in Figure 1.
The switching support tube assembly of prior art on load tap changer comprises mounting plate 111, bottom plate 112 and is connected the support tube 113 between the supporting plate up and down as shown in Figure 2.The upper end of support tube 113 directly and mounting plate 111 be fixedly linked, periphery at bottom plate 112 is provided with polylith mounting panel 1121 and connecting plate 1122, the lower ends downward of support tube 113 is extended with the adaptive connecting plate 1131 of connecting plate 1122 on polylith and the bottom plate 112, and by this connecting plate 1131 and connecting plate 1122 be connected realization and bottom plate 112 is fixedly linked.
Though the switching support tube assembly of the on load tap changer of prior art can play the effect that is fastenedly connected with stored energy mechanism and switching mechanism, but because it will be supported with the total weight of on-load shunting switch switch core, also to bear the enormous impact that is produced when stored energy mechanism releases energy simultaneously, its version that is fixedly linked by the connecting plate on connecting plate and the bottom plate seems thiner, and reliability is not high.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming that prior art exists, and provides a kind of switching support tube assembly of on load tap changer of new structure, to improve its connection reliability.
To achieve these goals, the utility model has adopted following technical scheme: a kind of switching support tube assembly of on load tap changer, comprise mounting plate, bottom plate and be connected the up and down support tube between the supporting plate, periphery at bottom plate is provided with polylith mounting panel and polylith connecting plate, be characterized in, described support tube comprises the support tube body and is arranged on the connecting ring of support tube body bottom, connecting ring is provided with adaptive notch of mounting panel on a plurality of and the bottom plate and the adaptive connecting hole of connecting plate on a plurality of and the bottom plate, and the support tube lower end is by this connecting ring and the interspersed mutually chimeric integral body that connects into of bottom plate.
The switching support tube assembly of above-mentioned on load tap changer, wherein, the external diameter of described connecting ring is greater than the external diameter of support tube body.
The switching support tube assembly of the utility model on load tap changer since with the external diameter of support tube body lower end amplify make connecting ring directly and bottom plate be rigidly connected, structure is simpler, connects more reliable.
