A control system for controlling two contactors at the same time

Abstract

The invention discloses a control system capable of simultaneously controlling two contactors. The control system comprises a CPU, a contactor power positive pole, a contactor power negative pole, a power-on execution switch, a power-on variety switching switch, a first switching switch, a first contactor actuator, a second contactor actuator, the first contactor and the second contactor, wherein the contactor power positive pole, the power-on execution switch, the second contactor actuator and the contactor power negative pole are connected to form a circuit loop A; the contactor power positive pole, the power-on execution switch, the first switching switch, the first contactor actuator and the contactor power negative pole are connected to form a circuit loop B; the power-on execution switch is electrically connected with the CPU, the first contactor actuator is electrically connected with the first contactor, and the second contactor actuator is electrically connected with the second contactor. According to the control system capable of simultaneously controlling the two contactors, through the power-on variety switching switch and the first switching switch, switching operations of attracting work between the first contactor and the second contactor are achieved, and three work states of the two contactors can be rapidly controlled.

Description

technical field [0001] The invention relates to a contactor control system, in particular to a control system for simultaneously controlling two contactors. Background technique [0002] In the prior art, the control of contactors is realized by contactor actuators or electromagnetic switches. This method can only control the switching state of one contactor. The current number of contactors is often only one, which is relatively single and cannot be realized. The complex control of a contactor, and in the electrical production line, often requires multiple contactors for complex control, the current generally is to arrange multiple contactors, contactor actuators or electromagnetic switches for separate control, which will lead to The control positions of multiple contactors cannot be centralized, and the operation is troublesome. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a control ...
