How to Deal with the Switch in Non-full Phase Operation?

(1) When single-phase switch automatically switches off, resulting in two-phase operation, if the reclosing operation of phase break protection starts does not work, it can immediately instruct the field to manually close once. If the closing fails, the remaining two-phase switches should be cut open.

(2) If the switch is two-phase disconnect, should immediately open the switch.

(3) If the non-all-phase switch cannot be opened or closed by taking the above measures, immediately open the line switch on the opposite side, and then disconnect the switch in the switch mechanism box.

(4) The bypass switch can also be used in parallel with the non-full-phase switch, and the non-full-phase switch can be unwound with the knife or the non-full-phase switch can be disconnected with the busbar switch in series.

(5) If the generator outlet switch is not in full phase operation, the active and reactive power output of the generator should be rapidly reduced to zero, and then treated.

(6) When the busbar switch is not in full phase operation, the current of the busbar switch should be adjusted and reduced immediately, and the busbar should be operated in single busbar mode. If necessary, one busbar should be cut off.
