Through the technical solution, the utility model has the characteristics of output is big, the magnetic leakage hangs down, generate heat few.
Description
Technical field
The utility model relates to reactor technical field, particularly relates to a kind of Three phase five post large-power radio-frequency reactor, can be advantageously applied to UPS, EPS power supply and high-end new energy field.
Background technology
Reactor is also inductor, the certain space scope occupied by it will produce magnetic field during a conductor energising, so the electric conductor of all energy current-carrying has perception in general sense.Reactance is divided into induction reactance and capacitive reactance, relatively the classification of science is that impedor (inductor) and capacitive reactance device (capacitor) are referred to as reactor, but first had inductor due to the past, and be called as reactor, so the said capacitor of people is exactly capacitive reactance device now, and reactor specially refers to inductor.
At present, traditional three-phase radio-frequency rector (frequency is greater than 1KHZ) adopts three-phase three-column EI type ferrite magnetic core mostly.Finding in long-term use procedure, there is following defect in the three-phase radio-frequency rector of this structure: power is not allowed to be easy to do greatly, and power is generally less than 10KAV; Magnetic is revealed serious simultaneously; During use, that local temperature easily occurs is too high for magnetic core, makes reactor bulk temperature uneven, reactor premature breakdown.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of Three phase five post large-power radio-frequency reactor, and this Three phase five post large-power radio-frequency reactor can realize function that is high-power, low magnetism leakage; Have that coefficient of safety is high, the feature of long service life simultaneously.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of Three phase five post large-power radio-frequency reactor, comprises horizontal iron core (2), longitudinal iron core (3); And the line bag (4) be wound on longitudinal iron core (3); It is characterized in that: described horizontal iron core (2) is become with lower horizontal iron core group by upper horizontal iron core; Described horizontal iron core and lower horizontal iron core are made up of two pieces of ferrite magnetic patch respectively, on composition horizontal iron core two pieces of ferrite magnetic patch between leave gap (1), leave gap (1) between two pieces of ferrite magnetic patch of the lower horizontal iron core of composition; Described longitudinal iron core (3) has five; The longitudinal iron core (3) of every root is made up of two pieces of ferrite magnetic patch; Gap (1) is left between two pieces of ferrite magnetic patch of the longitudinal iron core (3) of every root; Epoxy resin is cast with in described gap (1).
Further: the winding of described Three phase five post large-power radio-frequency reactor is excitation wire harness (5), and every root excitation wire harness (5) is formed by Multi-strand excitation twisting.
The advantage that the utility model has and good effect are:
1, owing to adopting five post magnetic core modes, limit, left and right sides core post is for compensating dispersion loss.Therefore make magnetic field more even.
2, because iron core adopts ferrite, simultaneously iron core by 14 block length square ferrite magnetic patch bonding forming.In three-phase and five-pole magnetic core, reserving the place of 7 adjusting plays, place, adjusting and fixed interval (FI) according to the magnetic field state of magnetic core and line bag combined error when assembling reactor, keep the consistency of three-phase electricity sensibility reciprocal.To reach technical requirement.
3, winding adopts Multi-strand excitation coiling effectively to avoid the kelvin effect of high frequency period. and improve ampacity, reduce temperature rise.
4, fill gap with multilayer loop epoxy resins sheet material, lower air-flow and concussion noise, improve high frequency blockage effect.
5, integrated poured epoxy resin improves reactor insulation level, fixed interval (FI) better, improves magnetic hysteresis stability, improves product useful life.
