    Abstract: To avoid incorrect operation of SF6 gas insulated switchgears, taking the typical single bus with subsection connection of 126 kV composite apparatus for example, this paper analyzed the electrical blocking principles of breaker, disconnector and earthing switch. Aiming at the defects existing in disconnector control loop, this paper designed a blocking circuit for power supply and control of disconnector, which realizes the misoperation-preventive locking function of equipment to guarantee equipment and personal safety.
    Key words: gas insulated switchgears; misoperation; electrical blocking; disconnector
