Power-off source etc.) power network is just largely affected in the way of harmonic wave using produced non-linear current and its load (electricity is aggravated
Network pollution).Power factor calibration system, the electric capacity of power capacitor and transmitting transformer constitute resonance and returned in other words
Road, experience have shown that the self-resonant frequency of this circuit is normally between 250 and 500Hz.Resonance can cause following adverse consequences：
The overload of capacitor；The overload of transformer and transmission equipment；To measurement and the interference of control system, to computer and Electrified Transmission
The interference of device；Resonance increase, i.e. Harmonics amplification；Voltage distortion.
The content of the invention
The utility model purpose is to provide a kind of soft magnetism current-limiting reactor, simple in construction, filtering decompression efficiency high, load
Greatly, radiate high, versatility is good, easy to maintenance.
In order to realize the above object the technical solution adopted in the utility model is：A kind of soft magnetism current-limiting reactor, including bone
Have around the home on frame, skeleton and magnetic core has been placed in coil, skeleton, the magnetic core includes stacked multiple magnetic chips, described coil

It is of the present utility model to have technical effect that：Traditional silicon steel sheet core, filtering decompression efficiency are replaced using soft magnetic bodies
Height, using stratiform steel platinum, load is big, and radiating is high.Soft magnetism current-limiting reactor of the present utility model can be applied to high-low pressure, structure letter
Single, versatility is good, and easy to maintenance, high-precision lamination eliminates inductance error between three-phase, it is ensured that reactor tuning precision.Meter
Calculation machine controls coil winding machine, and its winding is copper cash, is noted under vacuo with polyester resin, and each phase all will by fine-tuning standard
Seek regulation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to the drawings, have around the home on a kind of soft magnetism current-limiting reactor, including skeleton 1, skeleton 1 in coil 2, skeleton 1 and place
There is a magnetic core 3, the magnetic core 3 includes stacked multiple magnetic chip 3a, the termination of described coil 2 and connection terminal 5 are connected, described
The termination of coil 2 and the junction of described connection terminal 5 insulating corrosion layer 6 is set, the both ends of skeleton 1 are symmetrically arranged with
Attachment screw 8 is set in support group 7, support group 7, and described magnetic chip 3a is to set steel sheet between diskette, two diskettes
Platinum 3b.
Capacitor is when capacitive reactive power rate is compensated, often by harmonic current, inrush phenomenon and operating process electricity
The influence of pressure, causes capacitance damage and power factor to reduce, and needs to install current-limiting reactor additional in capacitor front end for this, to press down
System and absorption harmonic wave, protective condenser, it is to avoid harmonic voltage electric current and the influence of surge voltage electric current, improve the quality of power supply and improve system
System power factor, extends capacitor service life.Reactor of the present utility model replaces traditional silicon steel sheet iron using soft magnetic bodies
Core, filtering decompression efficiency high, using stratiform steel platinum, load is big, and radiating is high.Soft magnetism current-limiting reactor of the present utility model can be applied
Simple in construction in high-low pressure, versatility is good, easy to maintenance, and high-precision lamination eliminates inductance error between three-phase, it is ensured that electricity
Anti- device tuning precision.Computer controls coil winding machine, and its winding is copper cash, is noted under vacuo with polyester resin, each phase is all passed through
Fine-tune standard and require regulation.
In addition, the utility model also has the special feature that：The reactor can be three-phase and can also be single-phase, using high-quality
Magnetic chip 3a, through high speed special process punching, with burr is small, regular uniform, lamination it is neatly graceful, it is ensured that reactor operation is low
The performance of temperature rise low noise；Coil 2 uses insulated conductor, vertical around coiling through special purpose machinery, good with flatness, aesthetic in appearance
Advantage；Reactor is in assembling process, and all folders pass through anti-corrosion treatment including skeleton 1, and use non-magnetic material, and through pre-
Baking-vacuum paint dipping-heat, which is dried, solidifies this flow, makes reactor winding 2 firmly integral with magnetic core 3, when greatly reducing operation
Temperature rise and noise, effectively increase quality factor of reactor and reduce the effect of harmonic wave；Reactor appearance and size normative reference cabinet
Body size design, small volume, easy-to-connect greatly save user's cabinet cost investment.Reactor is used for capacitor by certain
Reactance Rate matches to form certain resonant tank, has reached the purpose of tuning filtering.Soft magnetism series electrical so of the present utility model
Anti- utensil is linear to spend, and loss is low, easy for installation, with good characteristics such as overheat protection functions.
