Zusammenfassung: | The invention relates to a control cubicle matched with GIS equipment for use. The control cubicle comprises three single-phase breaker auxiliary contacts and a non-full phase tripping outlet relay, wherein the three single-phase breaker auxiliary contacts are connected between a positive electrode and a negative electrode of a non-full phase loop; the three single-phase breaker auxiliary contacts are connected with the non-full phase tripping outlet relay in series after being connected with one another in parallel; and the control cubicle is characterized in that a power consumption element is connected to two ends of the outlet relay in parallel. According to the control cubicle matched with the GIS equipment for use provided by the invention, through the scheme that the power consumption element is connected to two ends of the outlet relay in parallel, the instantaneous power of the reaction of the outlet relay can be improved; and when voltage at two ends of the outlet relay reaches an action value, the power consumed by the relay cannot reach the action power, so that the action is prevented; and maloperation of the relay is effectively prevented. |
