A cooling system for an air insulated switchgear compartment, the cooling system comprising:
- a housing;
- a fan;
- and
- a flap,
- wherein the fan is mounted to the housing,
- wherein the flap is mounted to the housing,
- wherein the flap is positioned adjacent to the fan such that a rotational axis of the fan does not extend through the flap,
- wherein the flap is configured to move from an open position to a closed position due to a pressure difference from one side of the flap to the other side of the flap, and
- wherein the cooling system is configured such that gas and/or air cannot pass from one side of the housing to the other side of the housing directly through the fan along the rotational axis of the fan.
