Abstract
The invention provides an on-off anti-oxidation and impact-resistant device for an AC contactor of a three-phase economizer. The device is composed of an adjustment coil 1, a thyristor 2, the AC contactor 3, a buffer circuit 4, a secondary coil 5, an iron core 6, a primary-side coil 7 and a main control computer 8. By the device, the on-off of a switch at different shifts in a power saver can be realized, so that an effect of energy saving is achieved; meanwhile, by the device, a switch contact of the AC contactor can be prevented from being oxidized by spark caused by high voltage drop during instantly switching on an AC contactor switch, and the service life and the reliability of the AC contactor switch are prolonged and improved; and moreover, a thyristor switch can also be protected from heating due to long-time switching on, and the service life of the thyristor switch is prolonged.
