Description
Technical field
The utility model relates to a kind of reactive power compensation reactive capacitance.
Background technology
Reactive power compensation circuit is formed primarily of capacitor and reactor, and the capacitor of existing reactive power compensation circuit and reactor separate, connected by wire between the two, due to the heat generating components that capacitor is main, capacitor relies on own enclosure heat radiation, be difficult to the needs meeting heat radiation, capacitor life-span is short.
Existing reactive-load compensation capacitor is primarily of a few part composition such as capacitor core, metal shell and outlet structure.Reeling together with gathering into folds with insulating paper or plastic film by metal forming (as pole plate), form capacitor core by some elements, insulating part and securing member through press-fiting, and varnished insulation is oily.The lead-in wire of capacitor plate causes the outlet brace of outgoing line porcelain bushing pipe lower end after series and parallel.Capacitor metal casing filled with dielectric oil.Because capacitor core work is the meeting evolution of heat, there is heat overlap-add region between adjacent capacitor core, simultaneously, because metal shell is oval square, so the distance of this heat overlap-add region and metal shell is comparatively large, causes heat to be difficult to fall apart, easily cause capacitor core to burn out.And in view of metal shell is cuboid, volume is larger.
Utility model content
The purpose of this utility model is the deficiency overcoming the existence of above-mentioned prior art, and provides a kind of simple and reasonable for structure, good heat dissipation effect, the reactive power compensation reactive capacitance of long service life.
The purpose of this utility model is achieved in that
A kind of reactive power compensation reactive capacitance, comprise compensation condenser and reactor, capacitor core is provided with in compensation condenser, it is characterized in that: the vertical spiral winding of wire of described reactor, and wire is spaced from each other between each helicoid, reactor one end to be imbedded in compensation condenser and is electrically connected with capacitor core.Consider that reactive power compensation circuit operationally, reactor caloric value is much little compared with compensation condenser, so reactor and compensation condenser are linked together, simultaneously, three-dimensional winding is adopted to arrange in the wire of reactor, and do not contact between the wire of each circle, thus make the heat of compensation condenser fall apart by the wire of reactor, to improve its useful life.
The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, the wire of described reactor is banded copper sheet.
Described reactor also comprises iron core, and the vertical spiral winding of wire is located at its outer diameter.
Described iron core lower end is imbedded in compensation condenser.
Described compensation condenser is made up of metal shell, capacitor core and encapsulated layer, metal shell top is opened wide, capacitor core to be arranged in metal shell and to separate with metal shell inwall, metal shell inner top is stretched in reactor lower end, and capacitor core and reactor lower end are encapsulated in metal shell by encapsulated layer.Encapsulated layer can be epoxy resin layer; Encapsulated layer also can be have epoxy resin layer and explosion-proof lamp layer to form, and explosion-proof lamp layer is arranged on reactor and capacitor core is electrically connected position, all the other filling epoxy resin layers.
Described capacitor core is provided with three, the horizontal straight line of each capacitor core is in metal shell, between the capacitor core that metal shell is corresponding adjacent, position is provided with recess, make the heat of the heat overlap-add region formed between adjacent capacitor core comparatively closely can be delivered to the metal shell at recess place faster, heat is made to fall apart fast, to improve its useful life.
Be provided with fixing feet bottom described metal shell, fixing feet is arranged on described recess both sides, can promote the structural strength at recess place and facilitate client to install.
Described reactive power compensation reactive capacitance also comprises controller, and controller is connected with the reactor other end, and controller is provided with mains switch, guidance panel and communications line port.
The beneficial effects of the utility model are as follows:
(1) reactor of this kind of reactive power compensation reactive capacitance and compensation condenser link into an integrated entity, and, the vertical spiral winding of wire of reactor, between each helicoid, wire is spaced from each other, thus a part of heat produced when making compensation condenser work falls apart by reactor, improves the useful life of compensation condenser;
(2) wire of reactor is banded copper sheet, and compared with the wire that end face is rounded, the surface area of banded copper sheet is comparatively large, forms radiating fin, strengthens its radiating effect.
