Abstract

The invention discloses an AC contactor anti-electricity-dazzling module and relates to an anti-electricity-dazzling module. The AC contactor anti-electricity-dazzling module comprises a control circuit, a battery, an inverter and a switching circuit. The control circuit, the battery, the inverter and the switching circuit are connected in sequence; the control circuit is connected with the battery; and the control circuit is connected with the switching circuit and an AC contactor. With the application of the microelectronic control technology, the AC contactor anti-electricity-dazzling module can effectively prevent the AC contactor from being disconnected accidently due to the electricity-dazzling phenomenon, and meanwhile, can guarantee safety and reliability of an original loop control system; the anti-electricity-dazzling module can meet anti-electricity-dazzling application of the 630 A large-current AC contactor; and finally, electrical control of a factory is allowed to be stable and reliable, and production operation is allowed to be carried out continuously, safely and efficiently.

Description

technical field [0001] The invention relates to an anti-sway module, in particular to an anti-sway module for an AC contactor. Background technique [0002] The power supply system of large-scale continuous production factories such as chemical plants, oil refineries, and steel mills often encounters the phenomenon of short-term voltage loss in the power circuit, commonly known as "shock power", which will cause the control circuit to lose power. A large number of AC contactors are accidentally released. Many production equipment in the factory stop unexpectedly, which is also determined by the characteristics of the AC contactor itself. If the voltage loss time in the control loop is greater than 50ms or the voltage drops by more than 40%, the AC contactor is easily disconnected and the loop is restored. After the power supply, the contactor cannot automatically pick up and recover, and needs to rely on the control circuit to restart. In this way, due to the correlation b...
