  • Intelligent control system for high-voltage switch and control method thereof
    Patent number: 9362738
    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.
