Design and implementation of intelligent switch cabinet control device

With the development of power system, power equipment which is used to detect, control and protect gradually tend to be more informational, integrated and intelligent. In order to solve the problems of single function and low integration of switch cabinet control device, a multifunctional and high integration intelligent switch cabinet control device is designed and implemented in this paper. The control module of system based on ARM microprocessor, supplemented by the corresponding peripheral monitoring circuit and control circuit, which realize automatic heating and dehumidification control, fault alarm, over temperature alarm and voice prompt; it also can achieve the monitoring of real-time dynamic running and simulation of switchgear in remote environments through the communication with the host computer. Because of the complex electromagnetic interference environment of the control device, the shielding shell of switch cabinet control device is also designed. The experimental results verify the feasibility of the control device.
