Abstract

The invention discloses a control apparatus for preventing contactor adhesion, which comprises an input module, and the input module is separately connected to a first intermediate relay KA10, a second intermediate relay KA11 and a third intermediate relay KA12 by wires; the coil of the first intermediate relay KA10, the coil of the second intermediate relay KA11 and the coil of the third intermediate relay KA12 are respectively connected to a first contactor KM1, a second contactor KM2 and a third contactor KM2; an auxiliary contact of the first contactor KM1 is connected to a fourth input pin of a PLC, and an auxiliary contact of the second contactor KM2 and an auxiliary contact of the third contactor KM2 are connected together and are connected to a fifth input pin of the PLC. A normally closed contact is detected in real time by a wiring mode of the PLC and the auxiliary contacts on the contactors, so as to prevent the phenomenon of contact adhesion; and the coils of the intermediate relays on the apparatus are connected to the corresponding contactors to protect the apparatus and prevent the current in the apparatus from being too large.

Description

Technical field: [0001] The invention relates to a contactor anti-adhesion control device and a control method thereof. Background technique: [0002] In the field of industrial control, the controller has a large control capacity, can be operated frequently and remotely controlled, and is one of the important components in the automatic control system, especially suitable for the field of motor control. However, for motors that are frequently started, it is easy to cause the motor to run out of control due to contact adhesion of the contactor, causing mechanical accidents and personal injuries, and there is a great potential safety hazard. Invention content: [0003] The invention provides a contactor anti-adhesion control device and a control method thereof. The structure design is reasonable, and the contact adhesion phenomenon can be detected in advance during the operation of the motor, so that the motor can run safely and eliminate the existing The safety hazard is ...
