The capacitor core and the fuse discharge resistance of the condenser are poured in the casing by epoxy resins; the upper part of the condenser is provided with the outlet board; the capacitor core are processed by a special process of vacuum, warming and dipping in wax. The utility model has reasonable structure and good specific characteristic; in the electric network which is of 400 volt power frequency, the new dry-type power-saving low-voltage phase-shifting condenser is not only suitable for integrative compensation on low-voltage side but also for local capacitive compensation on inductive load side. The utility model has the advantages of dry type, self recovering, safety, energy saving, etc.
Description
The utility model relates to a kind of novel low pressure phase shifting capacitor.
The structure of low pressure phase shifting capacitor in the market still rests on the core body of aluminium foil and paper composition, flood with alkyl benzene, make shell with sheet metal, wear brass bolt in the porcelain vase and make exit, its structure is very outmoded, because the electrical characteristic of material is poor, production technology falls behind, therefore the specific characteristic of product is poor, and loss is big, poor safety performance.
It is 2 kilovars dry type, safety, self-healing, energy-saving low pressure phase shifting capacitor that the purpose of this utility model provides a kind of novel capacity, it is rational in infrastructure, be easy to combination, specific characteristic is good, the centralized compensation that in 400 couchers electrical network frequently, not only is suitable for doing low-pressure side, and be more suitable for making local compensation in inductive load is other, good power savings is arranged.
The utility model is the characteristic of energy self-healing when utilizing the good electric property of metallized polypropylene film and itself electric fault, and it is made capacitor body.Promptly liner volume and outside seal between around on two layers of metallized polypropylene film, it promptly is two utmost points of capacitor that two metal levels are drawn, and polypropylene film just becomes the medium of capacitor.Capacitor body two ends are sprayed with alloy-layer, respectively as the lead surface of capacitor two utmost points.Discharge resistance is connected across on this two end, get three so element connect through being connected on three outlet brass screws electrodes with three fuses after the vacuum waxdip technology in the triangle mode, irritating casting with epoxy resin becomes one in the enclosure, make this capacitor have dry type, safe and reliable, the reactive power compensation scope is wide, easily combination is applicable to the advantage of varying environment.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the longitudinal sectional drawing of capacitor core of the present utility model.
Fig. 3 is an electric hookup of the present utility model.
A low pressure phase shifting capacitor of being made up of housing (3), cap (1), capacitor main body (10), electrode (4) outlet board (12), its housing (3) forms with the acrylonitrile one butadiene one styrene copolymerized thermoplastic plastic injecting that forms.It is attractive in appearance, light and handy, physicochemical property is good, and housing (3) design is small combined structure, can very be combined into the capacitor group of various capacity easily by three assembly holes (11) of its lower bottom part.Housing (3) top is equipped with outlet board (12), contains three electrodes (4) on the outlet board (12), and two in order to the fixing joint pin (2) of cap (1), and is equipped with two and irritates blowholes (13).
Capacitor main body (10) is then by three groups of capacitor cores (8), fuse (6), and discharge resistance (7) is formed, and is irritated casting in housing (3) by epoxy resin (9), and electrode (4) links to each other with silver-plated weld tabs (5).
Capacitor core (8) is rolled into liner volume (15) by polypropylene film, about the number of turns 20 volumes, roll up (15) outside again around last two layers of metallized polypropylene film (16) at liner then, when reaching a constant volume, roll up outer the sealing (17) of the polypropylene film of the about 20-30 volume of last layer again, spray the lead surface (14) of last layer slicker solder kirsite with automatic metal spraying machine in whole volume core both ends of the surface at last, form through the vacuum waxdip of heating then as capacitor the two poles of the earth.
Three groups of discharge resistances (7) be connected into △ shape after capacitor core (8) is in parallel, its each end links to each other with silver-plated weld tabs (5) through fuse (6), about 60 amperes of fuse (6) current limlitings.
Constitute the metallic aluminium polypropylene film of capacitor core (8), its thickness 10-15 micron, it is big that this material is specially adapted to voltage fluctuation with the utility model of above-mentioned technology manufacturing, the place that frequency easily departs from be adapted to the low capacity motor and make local compensation, its energy-saving effect is remarkable.
The utility model also has following advantage:
1. with the injection molded housing (3) of acrylonitrile one butadiene-styrene copolymer, be not afraid of collision, extruding can be in various environment by any way, and the orientation is by dress.
2. use the synthetic resin embedding, reformed traditional technology with liquid infiltration, can not produce leakage, can not produce pollution to surrounding environment.
3. have good self-healing performance, self-healing immediately after the bad position religion punctures in the dielectric, capacitor recovers original function, long service life.
4. loss tg δ＜0.004 of the condenser loss tg δ that makes with metallized polypropylene film＜0.001(paper foil construction formula), own loss is little.
5. put resistance (7) in, break away from power supply after 1 minute at capacitor, inner residual voltage drops to below 50 volts, and discharge resistance (7) is gone up the active power of consumption less than 0.2 watt/kilovar.
6. interior dress fuse (6) when its inner member breaks down or short circuit phenomenon is arranged, can fuse immediately, makes capacitor core (8) break away from power supply, uses reliable.
7. its housing (3) is designed to fabricated structure, can very be combined into the capacitor group of various capacity easily, and electrical network is carried out optimum reactive power compensation.
