Aiming at the problems of low integration of intelligent high-voltage switches and imperfect primary and secondary integration design,this paper takes ZF11Z-252 kV intelligent high-voltage switch as an example,and proposes a high-integration design method.The method optimizes the network structure,designs and applies intelligent mechanisms, establishes a multi-dimensional state perception system,studies the state monitoring and evaluation technology based on the SVM algorithm,realizes system development, and conducts mechanical characteristics monitoring and evaluation experiments. The highvoltage switchgear in this paper can detect early hidden dangers in time through the application of comprehensive monitoring and evaluation technology,avoid the malignant development of faults, greatly improve the level of intelligence and digitization.It meets the requirements of a new generation of intelligent substations for high-voltage switchgear,and has good promotion and application value.
