Control method and control apparatus for switching apparatus

A control apparatus for a switching apparatus, wherein the switching apparatus comprises at least two switching devices connected in parallel, a minimum pulse width limit of a first switching device of the at least two switching devices is less than a minimum pulse width limit of a second switching device of the at least two switching devices, and the first switching device and the second switching device are in a cut-off state;

• and
• the apparatus comprises:
• a processor, configured to:
• obtain an on-state holding time of the switching apparatus;
• control, when the on-state holding time is less than the minimum pulse width limit of the first switching device, the at least two switching devices to remain in the cut-off state;
• and
• control, when the on-state holding time is greater than or equal to the minimum pulse width limit of the first switching device, the first switching device to perform a switching operation.

A switchgear, wherein the switchgear comprises a switching apparatus and a control apparatus for the switching apparatus, wherein the switching apparatus comprises at least two switching devices connected in parallel, a minimum pulse width limit of a first switching device of the at least two switching devices is less than a minimum pulse width limit of a second switching device of the at least two switching devices, and the first switching device and the second switching device are in a cut-off state;

• and
• the control apparatus comprises:
• a processor configured to:
