Abstract
The utility model discloses a high voltage electricity capacitor element who contains " U " type insulated paper, its characterized in that: the component is by high -pressure polar plate (4), low pressure polar plate (5), polypropylene film (6) and " U " type insulated paper (7) component, be equipped with in the middle of high pressure polar plate (4) and low pressure polar plate (5) two -layer polypropylene film (6), polypropylene film (6) edge, the equal hem of the other end all are good at to high pressure polar plate (4) and low pressure polar plate (5) one end, each covers " U " type insulated paper (7) high pressure polar plate (4) hem department and low pressure polar plate (5) hem department. The utility model discloses finally reduce the biggest electric field strength in high voltage electricity capacitor plate edge, improved the field distribution at polar plate edge, reduce partial discharge, reduced the temperature rise, improved the heat stability of component.
Description
Technical field
This utility model relates to high-voltage power capacitor field, is specifically related to a kind of high-voltage power capacitor element containing " U " type insulating paper.
Background technology
High-voltage power capacitor is the capital equipment of reactive-load compensation, effect is the reactive power compensating power system, improve power factor, thus reducing electric energy loss, improving quality of voltage and utilization rate of equipment and installations, therefore stablizing of power system is played vital effect by the safe operation of high-voltage power capacitor；High-voltage power capacitor is made up of parts such as fuse, case shell and leading-out terminals.Fuse is then made up of through press-fiting several elements, securing member and insulating part.
Existing high-voltage power capacitor element is rolled by polypropylene film and pole plate and forms, shortcoming is that high-voltage power capacitor insulation is comparatively weak, owing to pole plate edge electric field strength is excessive and skewness in running, easily produce shelf depreciation, cause component breakdown or the generation of case shell bulge accident, the safe operation of power system device is constituted serious hidden danger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-voltage power capacitor element containing " U " type insulating paper.
This utility model solves its technical problem and be the technical scheme is that a kind of high-voltage power capacitor element containing " U " type insulating paper, by high-pressure polar plate, low pressure pole plate, polypropylene film and " U " type insulating paper composition；It is provided with two layers of polypropylene thin film in the middle of described high-pressure polar plate and low pressure pole plate；Described high-pressure polar plate and low pressure pole plate one end are all longer than polypropylene film edge, the equal flanging of the other end；Described high-pressure polar plate flanging place and low pressure pole plate flanging place respectively cover " U " type insulating paper.
Described high-pressure polar plate and low pressure pole plate are aluminium foil material and consistent size.
Described " U " type insulating paper is polyimide composite film material, and its length is consistent with pole plate flanging length, and its thickness is 1/3rd of electrode thickness.
Adopt above structure compared with prior art, this utility model has the advantage that " U " type insulating paper can hinder the shelf depreciation at high-voltage power capacitor pole plate edge, thus reducing pole plate edge maximum field intensity, improve the Electric Field Distribution at pole plate edge, reduce temperature rise, improve the heat stability of element.
