Reactor be usually used in high power motor the startup stage.The starting current of threephase motor is generally 6 ~ 8 times of load current value, and the maximum during from electric motor starting returns to rated current when motor reaches rated speed, and according to the difference of payload, startup stage is lasted the several seconds and second do not wait to tens of.Power of motor is big more, and starting current is big more, its startup stage big electric current obviously electrical network constitute is impacted, power of motor is big more, impacts big more.For making the motor smooth starting, reduce of the impact of electric motor starting electric current to electrical network, the motor of being everlasting the startup stage seal in reactor, the principle of utilizing the inductance element electric current not suddenly change reduces more than 50% the electric motor starting electric current, reaches the effect of smooth starting.Since it only be used for motor the startup stage, the time of using in the actual place in circuit is shorter, works so can be designed as short time super-large current state under, this has just had the innovative design of over-saturation reactor.
In practical application; The device body main body of reactor be constitute by electromagnetic silicon steel sheets close with AC transformer Electromagnetic Design principle, structure such as Fig. 1 ~ shown in Figure 3; Comprise the core of reactor of forming by electromagnetic silicon steel sheets 1, be wrapped in the inductance coil 2 of core of reactor 1 periphery.Short time makes during duty cycle the over-saturation reactor produce very big electromagnetism concussion noise under the impact of over-saturation electric current; Extremely strong " drone " sound, the sound power level noise can reach the A sound level more than 110 decibels, user even can think that work is undesired; Produce sense of insecurity, influenced the use of product.The noise source of over-saturation reactor is the electric and magnetic oscillation of electromagnetic silicon steel sheets; The basic frequency of this vibration sound wave is 50Hz; And the frequency division of 50Hz and frequency multiplication (like 25Hz, 75Hz, 100Hz, 150Hz etc.); When a certain frequency in these frequency contents and over-saturation reactor device body and that the eigentone of casing of over-saturation reactor is installed is close or when being harmonious, reactor device body with casing is installed will be produced very big resonance noise.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of over-saturation reactor of vibration and noise reducing is provided, electromagnetism concussion noise is inhibited, de-noising effect can reach more than 20 decibels.
According to technical scheme provided by the invention; The over-saturation reactor of said vibration and noise reducing; Said over-saturation reactor is installed in to be installed in the casing, comprises the core of reactor of being made up of electromagnetic silicon steel sheets, and said core of reactor is installed on the base; Upper/lower terminal at core of reactor is provided with the iron core folder respectively, on core of reactor, twines inductance coil; Characteristic is: paste or brushing damping coating in the space between said core of reactor and inductance coil.
Mounting shock absorber on said base.
Interior at said installation casing is pasted with amortisseur bar.
Said amortisseur bar sticks on the middle part of the interior that casing is installed.
On the interior of said installation casing, paste amortisseur bar corresponding to the position at fixing vibration absorber place.
Said damping coating adopts pitch damping material or polyurethane IPN damping paint to process.
Said amortisseur bar adopts pitch damping material or polyurethane IPN damping paint to process.
The present invention is directed to vibration source and take the measure of separating vibration source and damping absorbed oscillation energy, noise is effectively controlled, electromagnetism concussion noise is inhibited, de-noising effect can reach more than 20 decibels.

Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like Fig. 4 ~ shown in Figure 6: the over-saturation reactor of vibration and noise reducing comprises core of reactor 1, inductance coil 2, iron core folder 3, base 4, damping coating 5, vibration absorber 6, casing 7, amortisseur bar 8 etc. is installed.
Over-saturation reactor of the present invention is installed in to be installed in the casing 7; Comprise the core of reactor of forming by electromagnetic silicon steel sheets 1; Said core of reactor 1 is installed on the base 4, at the upper/lower terminal of core of reactor 1 iron core folder 3 is set respectively, on core of reactor 1, twines inductance coil 2; Paste or brushing damping coating 5 in space between said core of reactor 1 and inductance coil 2;
As shown in Figure 4, on said base 4, vibration absorber 6 is installed, the installation position that vibration absorber 6 is installed in the over-saturation reactor is with the separating vibration source, and the vibration transfer that prevents the over-saturation reactor is to installing on the casing;
Take the measure of mounting shock absorber 6; To the vibration of vibration source take to isolate and absorbing after; Still have the partial vibration energy to transfer vibrations to casing 7 to be installed and casing 7 is installed through structure connection and transfer of air and produce resonance, the absorbing of installation casing 7 is important vibration damping point equally; As shown in Figure 6, be pasted with amortisseur bar 8 in the interior of said installation casing 7; The middle part that said amortisseur bar 8 sticks on the interior that casing 7 is installed with install on the casing 7 corresponding to the fixing inner surface of vibration absorber 6 positions, the noise and vibration of this position is maximum, i.e. amplitude or vibration acceleration maximum; The stickup quantity and the area of said amortisseur bar 8 are not limit, and paste position is the best with 1/3rd places at the middle part of installation casing 7;
