ABSTRACT
With the overall popularization of the unattended transformer management mode, the monitoring system of the unattended transformer is currently being widely used. The basic principle of the monitoring system of the unattended transformer is similar to this: Conduct real-time monitoring according to operation state data of the unattended transformer in the power grid (including operation state of equipment in master control room, real-time image of operation state of main transformer, breaker and disconnecting link, alarm information of intelligent devices for fire alarm, and burglary prevention) and transmit realtime operation state data to the monitoring center, so that management sta of the monitoring center can carry out control and analysis on the operation of each unattended transformer in accordance with realtime operation state data. The monitoring system of the unattended transformer increases the security and reliability of operation and maintenance of the unattended transformer, realizes visual monitoring and scheduling of the power grid, and makes regulation and operation of the power grid safer and more reliable. The traditional monitoring system of the unattended transformer is usually implemented through analog video monitoring technology, which is able to carry out on-site video surveillance and simple alarm information processing and transmission. However, limited by structure and principle, the traditional monitoring system of the unattended transformer is unable to realize remote and real-time integrated control so that management sta of the monitoring
center cannot understand and determine the operation state of the unattended transformer in a timely and accurate manner. For this reason, it is necessary to develop a new monitoring system of the unattended transformer so as to solve the problem that remote and real-time integrated control cannot be realized by the traditional monitoring system of the unattended transformer.
