Abstract
The utility model relates to a safety anti-explosion capacitor which is formed by mutually winding two strips of metallized thin-film materials, wherein the metallized thin-film materials are formed by high temperature and hot press after the winding, the end surface of a capacitor submodule is sprayed with a layer of welding surface of the capacitor submodule made of zinc tin alloy, a lead wire adopts a tinned copper wire, and an external packaging is formed by filling a yellow and fire-proof insulating adhesive tape and a fire-proof type epoxy resin and welding the axial lead wire. The utility model is characterized in that a metal coating in a metal thin-film is composed of a plurality of small quadrilaterals or rhombus metal coatings, and quadrilaterals or rhombuses are connected by fuses or melt wires. The utility model can storage, charge and discharge electric current when in normal operation. When the voltage and the electric current overload to run for exceeding the rated range, the fuses of the metal coating in the metal thin-film can fuse to break so as to achieve the purposes of protecting the capacitor or others electrical devices and enhancing the use safety of the capacitor.
Description
Technical field
The utility model relates to a kind of metallized polypropylene film medium, polyester film medium, the safe anti-explosion metallization film capacitor that is mainly used in the middle of the alternating current circuit, especially effective a kind of metal capacitor of capacitor for voltage protection and other electric equipment when exceeding rated voltage or electric current.
Background technology
At present; known metal film capacitor structure is by two metallized polypropylene film media; the polyester film medium is reeled mutually and is constituted capacitor; what the metalized film that general capacitor adopts was used is conventional zinc electroplated aluminum layer structure; bear high pressure and the heavy current ability is relatively poor; when capacitor in when work; voltage that it is subjected to or electric current all have strict demand; when voltage or electric current exceed its rated range overload operation; capacitor pole is fragile; power consumption equipment is normal to be used and the life-span thereby the capacitor that damages has influence on; general capacitor in use can not effectively be protected the damage to it of peak voltage and surge current, is easy to cause electric equipment to lose efficacy.
Summary of the invention
In order to overcome existing metal film capacitor effectively capacitor for voltage protection and electric equipment; the utility model provides the safety anti-explosive capacitor; purpose is to improve the deficiency of ordinary capacitor when overload operation; this capacitor can not only effectively be worked in normal environment; and also can effectively protect self, and continuous and effective ground work at some voltages and the unsettled occasion of electric current.
Safety anti-explosive capacitor of the present utility model is to be reeled mutually by two strip metal thin-film materials to form, metallized film materials is reeled after the high temperature thermocompression forming, spray one deck Zinc-tin alloy at the capacitor element end face and constitute the capacitor element solder side, lead-in wire adopts tinned wird, outer envelope adopts yellow fire-proof insulation adhesive tape, fire-type epoxy resin is filled out envelope, axial lead welds and constitutes, the profile of electric capacity is divided into axial flat, axially circular, epoxy resin enclosed, boxlike is sealed, the coat of metal is made of a plurality of tiny quadrangles or diamond-type metal coating in its metallic film, between quadrangle or the rhombus by fuse or melt fracture of wire and connect.
Safety anti-explosive capacitor of the present utility model is when operate as normal; line voltage distribution and electric current store and charging or discharging current by the fuse conducting in the capacitor; when voltage and electric current over range overload operation; burn in the capacitor the partial insurance silk or with the blown fuse in the whole capacitor device; and reach capacitor for voltage protection or other electric equipment, improve the fail safe that capacitor uses.
