    Abstract: The reliable action of the spring mechanism is vital to the safe and stable operation of the equipment. This paper took the failure of a 1 000 kV GIS of spring mechanism disconnector refusal to move in a UHV substation as an example, investigating and analyzing the cause. It discovered that the B-phase electrical generator of the refusal to move was broke down before the operation. And the broken down caused the disconnector failure. This research proposes solutions and operation and maintenance suggestions, such as changing the motor actuator or changing the braking resistor, and it provides a reference to the operation and maintenance of the UHV spring mechanism disconnector.
    Key words: spring mechanism; disconnector; refusal to move; operation and maintenance
