Abstract
An intelligent control system for a high-voltage switch and a control method thereof. The control system includes a control terminal (10) and a plurality of high-voltage switches (21-1, 21-2, . . . , 21-n-1, 21-n), each of which is controlled by an executive terminal (11-1, 11-2, . . . , 11-n-1, 11-n) respectively, wherein the executive terminal is connected to the control terminal via a communication network. The executive terminal includes a current detecting module (5), an analog/digital conversion module (4), a second communication module (2), a calculation processing module (3), a first communication module (1) and a switch control module (6) which controls the switch in real-time. The current detecting module detects a line current value. The analog/digital conversion module converts the line current value into a digital current value. The first and second communication modules are for communication. The calculation processing module compares digital current values and sends an alarm signal to the control terminal, or sends a tripping order to the high-voltage switch while sending an alarm signal to the control terminal.
