Research On Communication-capable Voltage Relay

First of all, my dissertation summarizes the actuality and development of low voltage apparatus and communication-capable low voltage apparatus and comments on literature about communication-capable low voltage apparatus.Secondly, the principle and the design project of communication-capable voltage relay were introduced. The low-voltage relay and the excess voltage relay are integrated into one relay, which can display the real time of the voltage of the circuit and the limit of voltage can be modified. Moreover, the communication-capable voltage relay can realize remote control, remote-adjust and remote-information.The hardware of the voltage relay are divided into five parts, which are central processing unit, A/D conversion, keyboard display, communication module and execution module. Moreover, flow chart of the communication-capable voltage relay is given in the dissertation.At the end of the dissertation I bring forward the measure to improve upon the communication-capable voltage relay and look forward to the tendency of the communication-capable relay.
