The cold-rolled silicon steel segmented iron core is partitioned into two parts by using an insulated I-shaped bar, and the heat dissipation area of the iron core is increased, so that the temperature rise of the reactor is well reduced; due to the adoption of the design, the size of the reactor can be reduced greatly on the basis of meeting the electrical performance; the power consumption is lowered greatly under the condition that the size is reduced; the iron core is made of an oriented cold-rolled silicon steel sheet, so that loss can be reduced greatly, and the temperature rise is reduced; and the iron core has a segmented structure, and a high-temperature cure adhesive is adopted for fixing through baking, so that the three-phase balance accuracy of the inductance value of the reactor and the mechanical strength of an entire component are ensured effectively, and noise generated by hysteresis contraction of a high-frequency iron core is reduced.
Description
Technical field
The utility model relates to the electric elements technical field that has magnetic core, relates in particular to the air-cooled reactor of a kind of novel dry type.
Background technology
Reactor also is inductor, will produce magnetic field in its occupied certain space scope during a conductor energising, so the electric conductor of all energy current-carrying has perception in general sense.Yet the inductance of the long straight conductor of energising is less, and the magnetic field that produces is not strong, and therefore actual reactor is lead coiled solenoid form, claims air core reactor; Sometimes in order to allow this solenoid have bigger inductance, just in solenoid, insert iron core, claim iron-core reactor.Reactance is divided into induction reactance and capacitive reactance, and relatively the classification of science is that impedor and capacitive reactance device are referred to as reactor, yet owing in the past inductor has been arranged earlier, and be called as reactor, so the said capacitor of people is exactly the capacitive reactance device now, and reactor specially refers to inductor.The filter reactor major part that is designed at home adopts the non-oriented silicon steel sheet iron core at present, and non-oriented silicon steel sheet is easily saturated under the high frequency state, so can only remedy this defective by increasing core section during design, and the size of reactor certainly will increase under this state, and Overall Power Consumption also can correspondingly increase.
The utility model content
Technical problem to be solved in the utility model provides the air-cooled reactor of a kind of dry type, and described air-cooled reactor has the advantages that volume is little, noise is low and low in energy consumption.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the air-cooled reactor of a kind of dry type, comprise coiling, last yoke core, upper clamping piece, the insulation support bar, external terminal copper aluminium row, the cold rolled silicon steel segment core, lower clamping piece and lower yoke core, the centre of coiling is provided with the cold rolled silicon steel segment core, be provided with the insulation support bar between cold rolled silicon steel segment core and the coiling, the two ends up and down of cold rolled silicon steel segment core are connected with yoke core and lower yoke core respectively, fixedly there is upper clamping piece the both sides, front and back of last yoke core by core through screw rod and nut, fixedly there is lower clamping piece the both sides, front and back of lower yoke core by core through screw rod and nut, the two ends up and down of coiling are provided with external terminal copper aluminium row, it is characterized in that described cold rolled silicon steel segment core, two halves before and after last yoke core and lower yoke core are separated into by the insulation I bar.
Preferably: the front and back sides of described reactor is provided with and connects the tightening bolt of going up yoke core and lower yoke core.
Preferably: be provided with clamping plate between described insulation support bar and the cold rolled silicon steel segment core.
Preferably: the outer surface of described cold rolled silicon steel segment core is coated with anticorrosive coat.
The beneficial effect that adopts technique scheme to produce is: described cold rolled silicon steel segment core is separated into two parts by the insulation I bar, increased the iron core area of dissipation, thereby well having reduced the reactor temperature raises, this kind design can satisfied the volume that reduces reactor on the basis of electric property greatly, under the condition that volume reduces, its power consumption also will reduce greatly; Iron core adopts the cold-reduced silicon sheet that orientation is arranged to make, and can reduce loss greatly, reduces temperature rise; Iron core is segmentation structure, adopts the high temperature setting glue baking fixing, has guaranteed the mechanical strength of reactor inductance value three-phase equilibrium precision and whole parts effectively, has reduced because the high-frequency core magnetic hysteresis is shunk the noise that produces; The core of reactor end face adopts the special-purpose coating varnish of even brushing black, thus improved reactor anti-corrosion capability.Described reactor has the characteristics of adverse circumstances operations such as volume is little, noise is low, anti-salt fog, vibration proof, is particularly useful for coastal and marine power supply-distribution system.
