The invention provides an intelligent terminal device adaptive to an intelligent
transformer substation, belonging to the technical field of power
automation. The intelligent terminal device adaptive to the intelligent
transformer substation comprises a master control board, an open-in plate, an operating loop plate, an open-out plate, an
interlocking plate, a simulating input plate, a display panel and a power source panel, wherein the master control board is used for realizing functions of logic judgment,
external communication, I / O (input / output) control and the like of the device; the open-in plate is used for collecting and accessing the quantity of state of a switch; the open-out plate is used for driving a loop
relay of the switch; the operating loop plate can be used for realizing functions of self-maintaining trip and close of a trip and close loop of a
circuit breaker, monitoring the trip and close positions, pressure locking of trip and close and preventing
tripping and the like; the
interlocking plate can be used for locking the switch loop such as an earthing knife-switch and the like; the simulating input plate has a function of collecting information of a state sensor; the display panel is used for displaying the condition of the device and the state of the switch; and the power supply panel is used for providing a power supply for the device. With the adoption of the technical scheme provided by the invention, a structure of open-out-
interlocking-operating loop is adopted for the operating control part of the switch, so that high infusion of the device with a primary device is realized, the reliability of the operating loop of the switch is enhanced, the CAN (controller
area network) communication is reserved; and the intelligent terminal device has expandability.
