Description
Technical field
The present invention relates to field of transmission equipment, and in particular to a kind of capacitor.
Background technology
Electric load such as motor, transformer etc. in power network, largely belong to inductive load, need in the process of running to
These equipment provide corresponding reactive power.After the reactive-load compensation equipments such as shunt capacitor are installed in power network, it can provide
The reactive power that inductive load is consumed, reduce the reactive power that electric network source is provided to inductive load, conveyed by circuit, by
In reducing flowing of the reactive power in power network, therefore it is electric caused by conveying reactive power to reduce circuit and transformer
Can loss.
Existing shunt capacitor, mainly it is made up of several parts such as shell, fuse and outlet structure.Fuse is only by several
Vertical element and insulating part laminates composition.Element electricity container paper（Or film）With kraft capacitor paper is compound does medium, use metal foil
Make pole plate and roll and form.Be filled with the dielectric oil for being used for impregnating fuse in shell, the lead of capacitor plate connection through string, simultaneously
Outlet structure is connected to after connection.By outlet structure shunt capacitor can be made to connect with other electronic components or electrical structure
Connect.Existing shunt capacitor structural stability is low, and service life is shorter, trace it to its cause be with the structure of present fuse and its
Manufacture has relation.For present fuse because not handling pole plate edge, generally existing has pole plate fringe field effect
Should.
Pole plate edge effect, refer to the larger electric field mutation of pole plate marginal existence, formation is local strong between making pole plate edge
Place, turn into the starting point of accident generation.According to the breakdown statistical conditions to shunt capacitor, most of breakdown points occur in pole plate
Edge.Especially when in fuse in the presence of the paper oil insulation defective workmanship such as bad is impregnated, easily trigger pole plate marginal discharge, even
Cause shunt capacitor explosion accident, serious harm power transformer etc. to be attached thereto and its nearby the safety of power equipment is transported
OK.
In consideration of it, it is badly in need of developing a kind of pole plate edge now by processing, without the electric capacity of pole plate fringe field effects
Device.
The content of the invention
The invention is intended to provide a kind of capacitor, occur to solve existing shunt capacitor because pole plate edge is untreated
The problem of pole plate fringe field effects.
To solve problem above, there is provided following scheme：
Scheme one：Capacitor in this programme, including shell, the outlet structure that is arranged on shell and be arranged in shell simultaneously
The fuse electrically connected with outlet structure；The fuse includes multiple element and the insulating part being stacked；Each element includes pole
Plate and roll medium between pole plate；The pole plate has the flanging that outwards turnover forms camber line edge；The turnover
Face is coated with the semi-conductor adhesive water layer that can carry out conductive and heat conduction inside and outside side.
Explanation of nouns：
Outwards：Point to the direction away from medium.
Inside and outside：Refer to the one side close to medium and the one side away from medium.
Principle and effect：
Pole plate is rolled to form discrete component together with medium, by the pole plate edge of each element according to one fixed width inside and outside two
Coating semiconductor glue layer on side；Coated pole plate edge is outwards turned down to form the flanging with camber line edge.So
Afterwards, by multiple element in parallel or in series, multiple element and insulating part are stacked to form fuse；Fuse is placed into and is equipped with
In the shell of insulating oil.Porcelain bushing shell is arranged on the casing cover of outer casing top surface, by the connection in the top and porcelain bushing shell of fuse
Piece connects.Casing cover is covered on shell, the terminals in porcelain bushing shell is stretched out upwards.
The pole plate edge of existing capacitor is not handled, and pole plate edge is generally right angle condition, it is also possible to jagged and not
Concordant phenomenon, the pole plate edge of unprocessed mistake is very sharp in a word.And the present invention by pole plate edge by outwards turning down one
It is secondary, i.e., pole plate is subjected to flanging processing, the edge for making pole plate after turnover be the flanging with camber line contour edge, i.e., after processing
Pole plate edge be arc shape, effectively reduce because sharp edges and caused by the mutation of the larger electric field in pole plate edge.Meanwhile
By coated in the semi-conductor adhesive water layer on flanging, preventing further gathering for the electric charge on pole plate edge, reducing pole plate side
Edge field strength.Efficiently solve existing shunt capacitor asking because the pole plate fringe field effects that pole plate edge is untreated and occurs
Topic.
Scheme two：Further, the outlet structure includes the porcelain bushing shell being arranged on shell, is provided with and uses in the porcelain bushing shell
It is connected come the connection sheet being connected with fuse and with connection sheet and stretches out the terminals of porcelain bushing shell.
Fuse makes other electronic components can be with by being electrically connected with terminals by being connected with connection sheet with terminals
Fuse in capacitor forms connection.Porcelain bushing shell is arranged on shell, is made to be formed on capacitor and is easy to and other electronic components
The outlet structure of electrical connection.
Scheme three：Further, the porcelain bushing shell is the porcelain bushing shell that inner side is coated with aluminium nitride ceramics layer.
Aluminium nitride thermal conductivity is good, and thermal coefficient of expansion is small, can play good radiating effect and heat shock resistance, aluminium nitride is also
It is electrical insulator, dielectric properties are good, can play insulating effect.Aluminium nitride ceramics layer, energy are coated on the inner side of porcelain bushing shell
It is enough that fuse in porcelain bushing shell, connection sheet and terminals are played with protection and guide effect, while can be by heat caused by them
Quick diffusing is gone out, and it is operated in a suitable operating temperature, avoids working at high temperature and reducing working life.
Scheme four：Further, the medium is kraft capacitor paper or capacitor film.
Kraft capacitor paper and capacitor film are all conventional media.
Scheme five：Further, the semi-conductor adhesive water layer is the heat conduction silicone that thickness is 0.1-0.2 millimeters.
Heat conductive silica gel has good heat conductivility and adhesive, except pole plate fringe field effects can be made effectively to reduce
Outside, moreover it is possible to flanging is sticked in more securely on pole plate, the shape at fixed polar plate edge, pole plate is turned over by flanging
After folding, the edge of pole plate is kept the shape at camber line edge, make the electric field mutation effectively drop formed originally because of sharp edges
It is low.And the thickness of 0.1-0.2 millimeters can make semiconductor glue on the basis of playing a role, it is unlikely to make semi-conductor adhesive water wave again
Take.
Scheme six：Further, the width of the flanging is 12-22 millimeters.
The length of pole plate is typically all the specification for having several restrictions, the flanging of 12-22 mm wides, can make pole plate side
Camber line edge is formed after edge turnover, on the basis of the adverse effect that pole plate fringe field effects are brought is eliminated as much as possible,
It is unlikely to make flanging width long and reduce the area of pole plate and then influence capacitance again.
