Abstract
The utility model relates to an adjustable alternating current capacitor, in particular to an adjustable alternating current capacitor formed by a plurality of metallized polypropylene film capacitorsand gear shifting switches. The utility model aims to solve the technical problem of providing an adjustable alternating current capacitor capable of not only adjusting capacity grades, but also saving resources. The adjustable alternating current capacitor comprises the metallized polypropylene film capacitors which have N capacity grades and are coaxially overlapped and wound; insulating layersfor separation are arranged among the metallized polypropylene film capacitors so as to form an inner core of the adjustable alternating current capacitor, and the inner core is placed inside an outer casing. Moreover, the gear shifting switches installed above the outer casing are used for switching the metallized polypropylene film capacitors with different capacity grades into a circuit, and the adjustable alternating current capacitor realizes the adjustment of various capacity grades, not only facilitates use, but also saves resources for remanufacturing the capacitors with new capacitygrades.
Description
Technical field
The utility model relates to a kind of adjustable AC capacitor, particularly a kind of adjustable AC capacitor of being made up of a plurality of metallized polypropylene film electric capacity and shifting switch.
Background technology
Along with development of science and technology, people have higher requirement to Electro Magnetic Compatibility and reliability, the fail safe of each electronic product, therefore we need use the capacitor of different model and specification at different electronic products, not only use inconvenience, have also caused the waste of resource.
The utility model content
The technical problems to be solved in the utility model provides a kind of adjustable AC capacitor that can the regulating capacitor capacity can economize on resources again.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of adjustable AC capacitor, comprise metallized polypropylene film electric capacity, hollow shaft and shell, described metallized polypropylene film electric capacity is wound on the hollow shaft, place in the shell, be installed with the neutral line in the described hollow shaft, the neutral line is connected on the bottom of described metallized polypropylene film electric capacity, and its innovative point is: also be connected with shifting switch on the described shell; Described metallized polypropylene film electric capacity is N, and centre in addition insulating barrier separates, and coaxial overlapping being wound on the hollow shaft, forms the adjustable AC capacitor inner core; Top at described N metallized polypropylene film electric capacity is connected to electric wire respectively, and binding post corresponding on described electric wire and the shifting switch connects.
Advantage of the present utility model is: can be arbitrarily made with new capacity levels by the coaxial overlapping coiling of the metallized polypropylene film electric capacity of N capacity levels, adopt this structure, the various resources of making required different capabilities rank capacitor have been saved, above described adjustable AC capacitor inner core, debug gear switch and can conveniently select suitable capacity levels, and on the top of described N metallized polypropylene film electric capacity respectively with corresponding binding post soldering connection on electric wire and the shifting switch, the shifting switch of conveniently replaced damage and adjustable AC capacitor inner core.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Fig. 1 is the structural representation of adjustable AC capacitor.
Embodiment
As shown in Figure 1, C1, C2, metallized polypropylene film electric capacity 1 coaxial overlapping being wound on the hollow shaft 5 of C3 capacity levels, centre insulating barrier 2 in addition separates, form adjustable AC capacitor inner core 3, place in the shell 10, the neutral line 6 that the bottom of described adjustable AC capacitor inner core 3 couples together is derived shells 10 by hollow shaft 5, and shifting switch 4 is housed on shell 10, C1, C2, metallized polypropylene film electric capacity 1 top of C3 capacity levels is connected to electric wire 8 respectively, binding post 9 corresponding on described electric wire 8 and the shifting switch 4 connects, and a termination of described shifting switch 4 has capacity output line 7.
During use, regulate shifting switch 4 to the C1 shelves, the bottom of C1, C2, C3 links to each other by the neutral line 6, by shifting switch 4 C2, C3 top and capacity output line 7 is disconnected the top access capacity output line 7 of C1; At this moment, have only access C1 in the circuit, promptly finish the operation of transferring the files of C1 shelves.Be adjusted to the C1+C2 shelves, the bottom of C1, C2, C3 links to each other by the neutral line 6, by the top access capacity output line 7 of shifting switch 4 with C1, C2, the top of C3 and capacity output line 7 disconnect, at this moment, C1, C2 are connected in parallel in the circuit, according to electric capacity computing formula C=C1+C2 in parallel, promptly finish the work of transferring the files of C1+C2 shelves.Metallized polypropylene film electric capacity 1 scalable of C1, C2, C3 capacity levels obtains the capacitor of C1, C2, C3, C1+C2, C2+C3, C1+C3, C1+C2+C3 capacity levels, by that analogy, adopt the how new capacity levels of metallized polypropylene film electric capacity 1 one-tenth capable of being combined of N capacity levels.Adopt this structure, not only make things convenient for and under different situations, select suitable capacitance levels, and realized more capacity levels, saved resource with the electric capacity of minority.And shifting switch and the inspection easy to connect of adjustable AC capacitor inner core are changed the parts that damage by the electric wire soldering, further saved resource.
