In order to meet the installation requirements of prefabricated type combination secondary equipment tank in standard distribution type intelligent substation, in view of the secondary protection devices front wiring that the display terminals are separated from the protection devices, the method of design and implementation of the display terminal for secondary protection devices front wiring is proposed. The display terminal based on the method above, which has good electromagnetic interference resistance and flexible deployment, adopts the independent CPU and communicates with the protection device ontology via Ethernet cable. The terminal is based on embedded real-time Linux operating system, which organizes the information in the adaptive way to be compatible with variable protection devices. The correctness and practicability of the display terminal are proved by the test results of China Electric Power Research Institute and the successful trial in one 220 kV substation.
