Description
Technical field
The utility model relates to a kind of reactor, the special-purpose reactor of particularly a kind of Active Power Filter-APF.
Background technology
At present, along with development of science and technology, various complexity, the accurate user to quality of power supply sensitivity constantly increase on the one hand; On the other hand, the use of the equipment of generation electric harmonic such as frequency converter, industrial power is increasingly extensive, makes that the harm of electric harmonic is more and more outstanding, sharp-pointed.Electric harmonic causes a large amount of active losses, damages electric equipment, causes various protection relay misoperations; Computer, image device etc. can't operate as normal, and interference communications punctures insulation, and compensation condenser makes up not brake application or the like.Its harm arrived must improvement degree.
Active Power Filter-APF is a kind of multifunctional electric power device that is used for dynamically suppressing harmonic wave and dynamic compensation reactive power, on the principle based on advanced person's instantaneous reactive power theory, filter detects the size of load current in real time, subtract each other with it after calculating corresponding first-harmonic value, draw the harmonic current and the reactive current that need compensation, high-power electronic switch on the control inverter bridge makes it to export required offset current, reaches the effect that suppresses harmonic wave and compensating reactive power.
Therefore, provide a kind of Active Power Filter-APF safe and reliable, stable performance special-purpose reactor, it is imperative to help to address the above problem.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and the special-purpose reactor of Active Power Filter-APF a kind of simple in structure, simple for production, safe and reliable is provided.
The technical scheme that the utility model adopted is for achieving the above object: the special-purpose reactor of a kind of Active Power Filter-APF, it is characterized in that being provided with two winding parallel connections and be sleeved on correspondence and snap together on the U type magnetic core that is " mouth " word shape, be provided with air gap gasket between its upper and lower magnetic core; Be provided with the outside and inboard that two outer skeletons, two inner frames penetrate two windings and are enclosed in the left and right pole of U type magnetic core respectively; Inner frame is set in parallel in its magnetic core that has two interior angle places, and outer skeleton connecting plate connects two outer skeletons, is provided with bed course between its underpart magnetic core and the base plate; Adopt screw cover cushion respectively, penetrate in the dermoskeleton frame end hole from the bottom plate hole bottom, and upper and lower magnetic core and base plate are fastened as one by nut; Outer skeleton connecting plate is connected and fixed a pair of outer skeleton.
The beneficial effects of the utility model are: main feature be about two windings respectively with opposite direction of rotation coiling, binding post is drawn in two winding parallel connections.Adopt open cage skeleton, inner frame, outer skeleton and outer skeleton connecting plate referring to Fig. 1, Fig. 2, constitute the cage skeleton, and pretensions such as magnetic core winding, base plate are fixed.This skeleton removes the gap that magnetic core up and down aligns formation above-below direction between alignment, the skeleton, for ventilation and heat provides outside the passage, and the also double effect that is fastenedly connected magnetic core and base plate.Open cage skeleton adopts the high strength macromolecular material to make, and satisfies the prefastened power requirement between upper and lower two magnetic cores and the base plate fully.And the connecting plate between two outer skeletons has guaranteed that the internal stress of two outer skeletons acts on respectively in two planes abreast.
Have guiding gutter on the air gap gasket between upper and lower magnetic core, it will make the easier inflow of insulating varnish in the dipping lacquer process, soak into, and the oven dry back obtains better heat-conducting effect, and two magnetic cores are sticked together firmly.Bed course between magnetic core bottom and base plate adopts insulation edge cloth, it is except that having not magnetic conduction, not producing the effect such as eddy current, because it is fine to the insulating varnish wettability, behind paint-dipping drying, magnetic core and base plate are bonded together firmly, and product can be dispelled the heat to the mounting panel in complete by metal base plate.The outer skeleton that is provided with improves the bulk strength of product greatly, thus satisfy stand to transport, the requirement of various mechanical shocks in the process such as installation, maintenance.
In a word, the utility model is simple in structure, and is reasonable in design, reduces volume, simplifies technology, can effectively reduce cost; Stable performance, safe and reliable, the useful life of having improved reactor simultaneously.Easy to use, be widely used, and be suitable for large-scale production.
