Abstract
A reactor for an active power filter is characterized in that an iron core is in a one-phase two-column structure, air gaps are reserved on two columns of the iron core, and the reactor adopts 35Q 150 high-quality-oriented silicon-steel sheets. The iron core is fixed by clamping pieces, an upper clamping piece and a lower clamping piece are tensioned and connected together by six pull screws, thereby being evenly stressed, high in strength and favorable for reducing noise. A working winding is composed of two windings and adopts a continuous structure, the two windings are respectively arranged on the two columns of the iron core, each winding connection wire is formed by connecting a plurality of wires in parallel, and then leading-out ends of the two windings are led to wiring terminals. Two working windings can be operated in parallel connection and series connection, thereby increasing flexibility in application. Air channel gaps are reserved among cakes of each coil, and air channel gaps are reserved between the coils and the iron core, thereby facilitating radiating very much and reducing temperature rise of the coils. The reactor for the active power filter is reasonable in design, simple in processing, stable in working, safe, reliable, long in service life, flexible in application and capable of being widely popularized and used.
Description
Technical field
The utility model belongs to reactor, and particularly a kind of Active Power Filter-APF is used reactor.
Background technology
Extensive application along with power electronic device; Mains by harmonics causes the situation of electric network pollution to be on the rise, and compares with passive filter, and Active Power Filter-APF has high controllability and fast-response; Filtering characteristic does not receive the influence of system impedance, but the harmonic wave that automatic tracking and compensating is changing.And Active Power Filter-APF has important function with reactor to filter response speed, effect.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of and process simple, working stability, Active Power Filter-APF safe and reliable, applying flexible is used reactor.
The technical scheme of the utility model is:
A kind of Active Power Filter-APF is used reactor, and its characteristics are: the iron core of 35Q150 high-quality orientation silicon steel sheet is single-phase two pole structures, on its iron core two posts air-gap is arranged; The work winding adopts the continous way structure; Be arranged on two posts of iron core, on each iron core column, be with H class F insulation tube, on H class F insulation tube by the coil of H level lead coiling; Between the cake of adjacent per two cake coils of coil, horizontal air channel is arranged, vertical air channel is arranged between iron core and the coil.
Iron core adopts upper and lower two clamping elements to fix, and has six to draw screw rod to be strained and fixed between upper and lower two clamping elements, and upper and lower two clamping elements are fixedly clamped by the crosswise fixed screw rod respectively.
The utility model effect is:
Iron core adopts clamping element to fix, and draws the screw rod tension to link together by six between upper and lower clamping element, and stressed even, dynamics is strong, helps reducing noise.The work winding is made up of two windings, adopts the continous way structure, is arranged on two posts of iron core, and wherein each winding connection is that multiple conducting wires composes in parallel, and the exit of two windings causes binding post then.Two work windings both can parallel running also can series operation, increased the flexibility in using.All leave between the cake of each coil and also leave the gap, air channel between gap, air channel, coil and the iron core, thereby be very beneficial for heat radiation, reduce coil temperature rise.The work winding is copper cash produces the coiling of insulating paper (NOMEX) H level lead with du pont company a coil.When coil temperature rise reaches 125K, can normal phase operation.This coil has high temperature resistant, and is fire-retardant, and fire prevention is explosion-proof, characteristics such as reliability height.The utility model is reasonable in design, processing is simple, working stability, safe and reliable, long service life, applying flexible, can generally promote the use of.

Embodiment
A kind of Active Power Filter-APF as shown in the figure is used reactor, and the iron core of 35Q150 high-quality orientation silicon steel sheet is single-phase two pole structures, on its iron core two posts air-gap is arranged; The work winding adopts the continous way structure; Being arranged on two posts of iron core, on each iron core column, being with H class F insulation tube, is the coil by the coiling of H level lead at H class F insulation tube; Between the cake of adjacent per two cake coils of coil, horizontal air channel is arranged, vertical air channel is arranged between iron core and the coil.
Iron core adopts upper and lower two clamping elements to fix, and has six to draw screw rod to be strained and fixed between upper and lower two clamping elements, and upper and lower two clamping elements are fixedly clamped by the crosswise fixed screw rod respectively.
This Active Power Filter-APF is used reactor, and its characteristics are that iron core is single-phase two pole structures, employing be 35Q150 high-quality orientation silicon steel sheet, there are air-gap in its iron core two posts and upper yoke.On two iron core column, iron core adopted clamping element to fix about two work windings were contained in respectively, drew the screw rod tension to link together by six between upper and lower clamping element.
The work winding coil is the continous way structure.The work winding by about two windings forms employing continous way structure.Wherein each winding connection is that multiple conducting wires composes in parallel, and the exit of two windings causes binding post then.
Two work windings both can parallel running also can series operation; When harmonic frequency was low, the use of can connecting was when harmonic frequency is higher; Can parallel connection use; Increased the flexibility in using, and the conversion of series and parallel occupation mode is accomplished by external control switch, gets final product manual switchover, also can be automaticallyed switch according to demand by controller.
All leave between the cake of each coil and also leave the gap, air channel between gap, air channel, coil and the iron core, thereby be very beneficial for heat radiation, reduce coil temperature rise.
The work winding is copper cash produces the coiling of insulating paper (NOMEX) H level lead with du pont company a coil.When coil temperature rise reaches 125K, can long-time running.Characteristics such as this coil has high temperature resistant, and is fire-retardant, and fire prevention is explosion-proof, and is safe and reliable.
