Vibration-damping and noise-reducing super-saturated reactor

Abstract

The invention relates to a vibration-damping and noise-reducing super-saturated reactor, wherein the super-saturated reactor is installed in the mounting box body and includes a reactor iron core composed of electromagnetic silicon sheets, wherein the reactor iron core is installed on the base; the upper end and the lower end of the reactor iron core are respectively provided with an iron core fastening piece; an inductance coil is wound on the reactor iron core. The space between the reactor iron core and the inductance coil is bonded or coated with a damper coating; a shock absorber is installed on the base; the inner surface of the mounting box body is bonded with a damper bar that is bonded in the middle part of the inner surface of the mounting box body; the inner surface of the mounting box body corresponding to the shock absorber is bonded with a damper bar. The invention effectively controls the noise and restrains the electromagnetic vibration noise by means of isolating the vibration source and absorbing the vibration energy and has more than 20 decibels of noise reduction effect.

Description

technical field [0001] The invention relates to a reactor, in particular to a super-saturated reactor for vibration reduction and noise reduction. Background technique [0002] Under the guidance of the national new energy policy, a large number of energy-saving products with innovative thinking have been designed and applied to actual production, including the innovative design of supersaturated reactors. [0003] Reactors are often used in the starting phase of high-power motors. The starting current of a three-phase motor is generally 6 to 8 times the rated current value. From the maximum value when the motor starts to the rated current when the motor reaches the rated speed, the starting phase lasts from several seconds to tens of seconds depending on the load. Wait. The greater the power of the motor, the greater the starting current. Obviously, the large current in the starting phase constitutes an impact on the power grid. The greater the power of the motor, the gre...

AI Technical Summary

Problems solved by technology

Under the impact of super-saturated current during short-time working period, the super-saturated reactor will produce a lot of electromagnetic vibration noise, extremely strong "hum" sound, and the sound power level noise can reach A sound level of 110 decibels or more. Users may even think that Abnormal work, resulting in a sense of insecurity, affecting the use of the product
