At present

dynamic indicating of primary system diagram

guards against incorrect operation

and intelligent manipulation are usually achieved by several independent electronic devices in a high-voltage switchboard of power system.A switchboard is often equipped with many components from different factories

which will inevitably bring about the shortcomings of low integration

complex wiring

and lower reliability to weaken the automatic operation function of the switchboard.By analyzing the basic functions that an intelligent control device should possess

principle design and several key technologies for an intelligent manipulation device are presented in this paper.This new device can realize simulation display of a primary system diagram

remote/local operation

temperature/humidity intelligent control

and voice-prompt of fault operation.
