Abstract
The utility model relates to an oil-filling hole sealing device for an electric power capacitor, which is mainly composed of a positioning cover, a spring, a pallet, an inner sealed cushion ring, a pull-seal screw bolt and a pressing plate. A cover opening of the positioning cover is welded or riveted with the inner side of an oil filling hole, and a cover wall is provided with an oil through hole; one end of the spring bunts a cover bottom, and the other end of the spring bunts the pallet; one surface of the pallet facing the oil filling hole is provided with the inner sealed cushion ring, the center of the pallet is provided with a screw hole, and the outer side of the oil filling hole is provided with an outer sealed cushion ring and the pressing plate; the pull-seal screw nail penetrates through the pressing plate, the cushion ring and the oil filling hole to be screwed into the screw hole of the pallet, by which the pallet, the pressing plate and the inner and the outer sealed cushion rings are pulled tightly to seal the oil filling hole. The utility model is used for filling oil, and has the advantages of convenient operation and good tightness; by the oil-filling hole sealing device for an electric power capacitor, the pressurization and the oiling of a single capacitor can be realized, and proper residual oil-pressure can be reserved.
Description
The utility model relates to the spare and accessory parts of oil-filling type power capacitor, and is especially relevant with power capacitor oil filler point sealing device.
Oil-filling type power capacitor oil filler point is that capacitor impregnant injects a passage in the capacitor, requires sealing after the oiling.At present, the oil filler point structure of domestic this class capacitor is roughly divided three kinds with the correction oil injection method difference: open oil filler point on the A. capacitor cover, product immerses in the oil of oil groove, in the impregnating agent flows into capacitor device, covers seal closure and soldering sealing then; B. a lid mouthful weldering oiling nut, the oiling pipeline links to each other with screw thread with capacitor, makes oil enter capacitor, removes the oiling pipeline after having annotated oil, and tightening also with blind nut, soldering seals; C. the lid mouthful oil filler point weld with copper tube and oiling pipeline, after the oiling cover end with the red copper pipe clamp flat and pinch off, seal with soldering then.Above-mentioned three kinds of oil filler point structures make refueling operation extremely bother owing to all need soldering sealing after the oiling, use once the oiling sealing simultaneously, and capacitor can not defuelling, reuses.
The purpose of this utility model is that a kind of power capacitor oil filler point sealing device will be provided, and it can make the oiling operation become simple, and good seal performance.
The utility model mainly by locating cover, spring, pallet, interior seal washer, draw envelope screw and pressing plate to form.Locating cover is a peviform cover, at the bottom of its basin or on the side oil through is arranged, and locating cover welding or riveted and fixed are on the capacitor cover inboard of oil filler point.Spring is powerful wire spring, and the one crown at the bottom of the locating cover basin, and the other end heads on pallet.Pallet web shape and size are complementary with the shape and the size of locating cover basin mouth section, it is embedded with interior seal washer towards the oil filler point side, this face center have one with draw the screw that is complementary of envelope screw, screw can not pass pallet, pressing plate is equipped with in the oil filler point outside at capacitor cover, there is screw perforation at the pressing plate center, draws to seal to screw in the screw at inboard pallet center after screw passes pressing plate and oil filler point.In order further to improve the sealing property of this oil filler point sealing device, can add an external seal packing ring being close between the capacitor oil-hole cover outside and the pressing plate.In addition, for corrosion or damage attractive in appearance and that prevent pressing plate, draw envelope screw and other parts, can add a guard shield in the pressing plate outside.
The utlity model has following advantage: 1. make things convenient for oiling, when with the oiling of this oil filler point sealing device, only need that special-purpose pump nozzle is inserted oilhole and get final product oiling, oiling finishes, taking off pump nozzle can seal voluntarily, covers external seal packing ring, pressing plate again, tightens and draw the envelope screw to get final product, and need not the soldering sealing of trouble, saving of work and time, easy to operate; 2. can realize product separate unit pressurization oiling new technology, make product keep suitably interior and press the quality of to enhance product performance; 3. inside and outside double-deck packing ring, sealing property is perfectly safe.The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a structural representation of the present utility model
Among the figure: 1. locating cover 2. springs 3. pallets 4. draw seal washer 6. external seal packing rings 7. pressing plates 8. guard shields in the envelope screw 5.
As shown in Figure 1, the utility model by locating cover 1, spring 2, pallet 3, draw envelope screw 4, interior seal washer 5, external seal packing ring 6, pressing plate 7 and guard shield 8 to form.Locating cover is the round basin cover of little, two steps in the big end of a bite, and its lower bottom tub directly encloses with spring 2 and matches, and basin bore encloses then and matches with the web of pallet 3 on it, and its side and end basin have oil through.The basin mouth limit of this locating cover is fixed on capacitor cover oil filler point madial wall with the method for welding or riveted joint.Spring 2 is powerful wire spring, and the one head term at the bottom of the locating cover basin, and the other end then heads on pallet 3 because the present embodiment pallet has a dop, so the other end of the spring 2 of present embodiment just in time suit the dop of pallet and head on pallet.The other end is a disk body to 3 one on the pallet of present embodiment in order to be installed on the dop in the spring, seal washer 5 in disk body is embedded with towards the oil filler point side; Have simultaneously at the center of this face one with the screw that draws envelope screw 4 to be complementary, its hole depth can not be passed pallet, is advisable with pallet thickness 2/3.In the oil filler point outside of being close to capacitor cover external seal packing ring 6 is housed, refilled pressing plate 7 in this packing ring outside, there is the perforation that is complementary with screw 4 at the pressing plate center, draw the envelope screw to pass in the screw at pallet center of pressing plate, outer washer and oil filler point precession inboard, and pallet, pressing plate are strained the oil filler point that seals up on the capacitor shell wall with inside and outside seal washer.In order to prevent that screw and parts corrosion thereof from damaging, and is clamped on the pressing plate outer side edges with guard shield 8, and fixes with epoxy resin.
Claims (3)
1. power capacitor oil filler point sealing device, mainly by locating cover, spring, pallet, interior seal washer, draw envelope bolt and pressing plate to form, it is characterized in that: locating cover is a peviform cover, at the bottom of its basin or on the side oil through is arranged, locating cover welding or riveted and fixed are on the capacitor cover inboard of oil filler point, spring is powerful wire spring, the one head term at the bottom of the locating cover basin, the other end then heads on pallet, pallet web shape and size are complementary with the shape and the size of locating cover basin mouth section, it is embedded with interior seal washer towards the oil filler point side, this face center have one with draw the screw that is complementary of envelope screw, screw can not pass pallet, in the oil filler point outside of capacitor cover pressing plate is housed, there is screw perforation at the pressing plate center, draws the envelope screw to pass pressing plate, behind the oil filler point in the screw at the pallet center of precession inboard.
