Design of Intelligent Control of High Voltage Switch Cubicle
ABSTRACT: Intelligent control is one of the most important direction to the switch equipment development, also is a new generation of electrical switches, which synthesizes microcomputer technology, digital processing technology and network communication technology. In this paper, the implementing methods for intellectualized electrical apparatus are discussed. The structure of hardware system is provided. The principles of various circuit units are introduced, i.e. the single chip microcomputer system, the data-collecting system for analog signals, the I/O circuit for switch quality, the interface circuit for serial communication, the circuit for hardware clock and self-restoration, and the man-machine conversation module. The algorithm for microcomputer measurement and protection are offered. Also some anti-interference technique were introduced, such as isolation, filter, self-diagnosis and so on.
