Abstract

The utility model provides an on-load tap-changer oil chamber, which comprises an insulating cylinder and a cylinder bottom, wherein the insulating cylinder and the cylinder bottom are integral structural members which are connected into integration. The on-load tap-changer oil chamber of the utility model has the advantages that the former two components, the insulating cylinder and the cylinder bottom, are formed as an integral body by an integral forming, and thus, the bottom of the oil chamber has absolute sealing performance, has the advantage of simple structure, exempts multiple mechanical processing, reduces manufacturing links and reduces production cost.

Description

The loaded tap switch oil chamber
Technical field
The utility model relates to a kind of electric equipment, particularly a kind of loaded tap switch oil chamber.
Background technology
The loaded tap switch oil chamber is used to carry Switch main body, fixing output contact, and the dielectric of on load tap changer and the dielectric of transformer are isolated.The loaded tap switch oil chamber of prior art as shown in Figure 1, its partial structurtes comprise an insulating cylinder 11 and a tube end 12 as shown in Figure 2.Insulating cylinder 11 and tube link to each other by 13 riveted joints of uniform rivet at the end 12, and by O-ring seals 14 sealings, also are provided with pressing plate 16 above O-ring seals 14.Be provided with a plurality of installing holes 15 that are used to install the output contact at insulating cylinder 11 middle parts.
Though the insulating cylinder of the loaded tap switch oil chamber of prior art and the connected mode of tube at the end can play sealing function, owing to reasons such as its structures, in use have following problem:
1, owing to the sealing property of grease chamber is had relatively high expectations, therefore in the processing assembling process, also higher to insulating cylinder and the fit dimension requirement of tube at the end, cause processing difficulties, and time-consuming;
2, the mode that seals with O-ring seals is to matching requirements height, operating difficulties, poor reliability;
3, because on load tap changer will carry out long high temperature drying processing with transformer before use, in use to stand medium--the long immersion of oil, therefore require employed O-ring seals to have high-quality quality high temperature resistant, oil resistant, in case O-ring seals lost efficacy, to cause grease chamber's seepage, cause the accident.
Summary of the invention
The purpose of this utility model is in order to solve existing in prior technology the problems referred to above, a kind of loaded tap switch oil chamber of new structure to be provided.
The purpose of this utility model realizes by following technical scheme: a kind of loaded tap switch oil chamber, comprise the insulating cylinder and the tube end, and be characterized in that the described insulating cylinder and the tube end are the integral structure component that fuses.
The utility model loaded tap switch oil chamber is because with two original parts--and the insulating cylinder and the tube end, are made of one the integral body of moulding, thereby make the bottom, grease chamber have absolute sealing property, need not worry again that mismachining tolerance, assembling error or O-ring seals inefficacy cause seepage; And simplify the structure, exempted multiple tracks machining, saved operation with O-ring seals sealing and rivet, significantly reduced the manufacturing link, reduced production cost.
Description of drawings
Fig. 1 is the structural representation of prior art loaded tap switch oil chamber;
The A portion enlarged drawing of Fig. 2 Fig. 1;
Fig. 3 is the structural representation of the utility model loaded tap switch oil chamber.
Embodiment
Referring to Fig. 3, the utility model loaded tap switch oil chamber comprises the insulating cylinder 21 and the tube end 22, and the insulating cylinder 21 and the tube end 22 are the integral structure component that fuses.On insulating cylinder 21, be provided with a plurality of installing holes 23 that are used to install the output contact.
After integral body is made with cylindrical shell in the utility model loaded tap switch oil chamber, insulating cylinder and tube do not have annexation at the end, thereby the bottom, grease chamber has absolute sealing property, the leakage problems that causes owing to mismachining tolerance, assembling error or O-ring seals inefficacy in the time of can not appearing at the manufacturing of employing connected mode; And simplify the structure, significantly reduced the manufacturing link, reduced production cost.Have tangible economic benefit and practical value.
