Description
Technical field
The utility model relates to a kind of capacitor, and more particularly, it relates to a kind of economical power capacitor.
Background technology
Self healing capacitor adopts single-layer polypropylene film as medium, surperficial evaporation the thin metal of one deck as conductive electrode.In the time applying too high voltage, polypropylene screen electricity weakness is breakdown, and breakdown point impedance obviously reduces, the current density flowing through sharply increases, and the coating that makes to metallize produces high heat, and breakdown point metallic conductor around evaporates rapidly loss, form coat of metal clear area, breakdown point recovers insulation automatically.
Capacitor unit group adopts the explosion-proof manufacture craft that stretches, in the time of capacitor internal fault, can produce a succession of self-healing property collapse causes capacitor element internal pressure to increase, for avoiding causing capacitor case rupture, capacitor element internal structure is designed with pressure and breaks type dump mechanism, these protective devices are that nationality causes upper cover to heave by interior pressure increase, and the Copper Foil of weakness processing is pulled off and isolated from power, prevent that secondary disaster from occurring.
Economical power capacitor of the prior art, after capacitor internal pressure becomes greatly, can directly the lead-in wire that is placed in its inside be broken, but the pressure of economical power capacitor inside change sometimes greatly just causes greatly in instantaneous change because electric current is unstable, but because this situation also will be broken lead-in wire, thereby economical power capacitor is damaged and cause the direct waste to economical power capacitor.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of economical power capacitor, pressure that it can effectively solve economical power capacitor inside in prior art becomes large and just causes greatly in instantaneous change because electric current is unstable, but because this situation also will be broken lead-in wire, thereby economical power capacitor is damaged and cause the problem of the direct waste to economical power capacitor.
For achieving the above object, the utility model provides following technical scheme: a kind of economical power capacitor, comprise housing, described housing has been wholely set cap and body, between described cap and body, be connected with electroconductive elastic sheet, described cap slippage is connected with sliding plate, the outer rim of described sliding plate and the circumferential butt of the inwall of cap, the relative body direction of described sliding plate is provided with conduction insertion tube, described body is provided with and is plugged in the conduction inserting column of conduction in insertion tube, the maximum slippage that length is less than sliding plate that patches of described conduction inserting column and conduction insertion tube.
By adopting technique scheme, economical power capacitor can, by two circuits of electroconductive elastic sheet and conduction insertion tube and conduction inserting column, be realized the conducting of circuit, allows economical power capacitor realize normal work, it is unstable and while causing electric current excessive that electric current in the middle of operational environment occurs, the electric current flowing through in economical power capacitor also will become large thereupon, thereby cause the heating up of economical power capacitor, the rising of temperature will cause the expansion of the air in cap, owing to being provided with the sliding plate of the connection of slippage with it in cap, after the air in housing expands, sliding plate will be thought the top motion of cap, after the skidding distance of sliding plate reaches certain limit, conduction insertion tube will be separated with conduction inserting column, thereby economical power capacitor is quit work, the danger of having avoided economical power capacitor to work under the condition of high temperature, after the temperature in economical power capacitor is recovered normally, air in cap also will no longer expand, now sliding plate will be returned to reset condition again along with cap inside is divided into the pressure in the space in two chambeies balance by sliding plate, conduction insertion tube will be docked again with conduction inserting column, now economical power capacitor will normally asked lower task again, avoid due to moment erratic current waste that economical power capacitor is caused.
The utility model is further set to: one end of the relative sliding plate of described cap offers venthole.
By adopting technique scheme, at sliding plate, during to the top slippage of cap, the air between sliding plate and the top of cap can be discharged by venthole, makes slippage more smooth.
The utility model is further set to: between described sliding plate and the top layer of cap, be connected with spring.
By adopting technique scheme, in the time that the temperature in cap returns to normal working temperature gradually, sliding plate can, by the elastic force of spring, reset to original normal operation position by sliding plate, and the work of economical power capacitor is more stable.
The utility model is further set to: described conduction inserting column is provided with elastic bumps with the part convex that patches of conduction insertion tube.
By adopting technique scheme, by being arranged on the elastic bumps being outwards convexly equipped with on conduction inserting column, the contact performance while making to conduct electricity inserting column and the docking of conduction insertion tube is better, can arrive fully contact, and operating state is more stable.
The utility model is further set to: described conduction inserting column relatively conducts electricity one end of insertion tube and is set to round end.
By adopting technique scheme, conduction inserting column is inserting conduction when insertion tube, is set to round end because conduction inserting column conducts electricity one end of insertion tube relatively, makes, in conduction inserting column insertion process, to reduce with the relative friction forces of conduction insertion tube, increases the service life.
Compared with prior art, the utility model has the advantage of: the pressure that effectively solves economical power capacitor inside in prior art becomes large and just causes greatly in instantaneous change because electric current is unstable, but because this situation also will be broken lead-in wire, thereby economical power capacitor is damaged and cause the problem of the direct waste to economical power capacitor.
