POWER DISTRIBUTION LINE SWITCHING METHOD AND CONTROL SYSTEM THEREFOR

摘要

A power distribution line automation switch control system comprises a microprocessor for receiving the detecting results from a current transformer, a current detection portion connected to a transformer on the power source and a voltage detecting portion connected to a transformer on the load to control all operation of a system and including a CPU, a timer, an interrupt controller, a decoder and an A/D converter; a ROM; an EEPROM; a SRAM; a memory for storing the information and data of said microprocessor; a display portion in the form of an LCD for representing information of currents, voltages, ground currents and information inputted by the selection of users according to the control of said microprocessor; a communication module for converting the inputted modem information into the digital series information, or the digital information from the microprocessor into the modem information; and an inputting/outputting portion for supplying the opening signal and the throwing signal from said microprocessor to an opening operation portion and a throw operating portion while supplying the state signal from a contacting point to said microprocessor, whereby the switch state is remote-controlled to exactly identify the operation state of a system, and the use of the microprocessor enables the record and keeping according to the communication and the operation state.
