A monitoring-and-control drawer (138) for an electrical connection enclosure comprises a front part (300) comprising a ventilation grille (326), a back portion (348) at which a back ventilation region is provided and functional elements (362). The heat generated by the functional elements is removed by an air flow (FL1) which enters the functional unit via each air grating in the front part and re-emerges from the functional unit via the back ventilation region, having passed right through the functional unit. The back portion belongs to a base of the drawer to which the functional elements are attached and comprises a group of upstream connectors (354) connected to an electricity source, a group of downstream connectors (356) connected to an electrical load and a ventilation orifice (358) which is part of to the back ventilation region and which is located between the group of upstream connectors and the group of downstream connectors.

The present disclosure relates to a distribution board ventilation system including a circulation chamber serving as a passage for air circulation and arc discharge; a first compartment provided at one surface of the circulation chamber; a second compartment which is adjacent to the first compartment and provided at the other surface adjacent to the one surface of the circulation chamber; a first discharge door mounted on the one surface of the circulation chamber to open the first compartment; a second discharge door mounted on the other surface of the circulation chamber to open the second compartment; and a linking means which is mounted between the first discharge door and the second discharge door and ensures that the open states of the first discharge door and the second discharge door are mutually exclusive.

A wind turbine with an electric converter module having a first section forming a first enclosure capable of withstanding a pressure from an arc flash inside the first enclosure. The first enclosure houses an electric protective device electrically connected between a first electric conductor and the second electric conductor. A second section is arranged adjacent to the second side wall of the first section, and forms a second enclosure housing an electric converter system connected to the second electric conductor and a third electric conductor to allow conversion of electric power from the third electric conductor to electric power to the second electric conductor. A door in the second section serves to allow service personnel to access components of the electric converter system from outside the enclosure.

Disclosed is an air conditioning arrangement, in particular a cooling arrangement, at least comprising a switchgear cabinet (1) that has a supporting device (4). Electric and/or electronic devices (2) that are to be air-conditioned are disposed in rows on top of and next to one another on the front side (17) of the supporting device (4), said front side (17) facing the doors of the switchgear cabinet. The disclosed air conditioning arrangement is characterized in that the devices (2) in the switchgear cabinet (1) can be at least partially air-conditioned by at least one heat sink (50), each of which forms an autonomous component.

A power cabinet, which includes a cabinet body and an electric reactor, a power unit and a switch arranged in the interior of the cabinet body. In the interior of the cabinet body of the power cabinet, the electric reactor is arranged close to a first side in the interior of the cabinet body, and the power unit and the switch are arranged on a second side in the interior of the cabinet body, opposite to the first side. Moreover, these electric reactor, the power unit and the switch are all located in a lower space. In addition, in the power cabinet, the electric reactor and power unit dissipate heat in different chambers from the switch dissipates heat.

A power conversion device includes an electronic component, a cooler, a housing, protruding pipes, and annular seal members. Each of the seal members includes a seal body portion interposed between a corresponding one of the protruding pipes and the housing, and a flange portion extending outward from the seal body portion in a radial direction and contacting an outer surface of the housing from an axial direction. The housing includes a peripheral wall surface formed to surround the flange portion from an outer peripheral side, and an annular groove portion formed along an outer peripheral edge of the flange portion inside the peripheral wall surface. The peripheral wall surface is formed to extend outward, in the axial direction, from an axial contact surface of the housing contacted by the flange portion.

A split door submersible housing for an electrical distribution system includes a cabinet body defining an interior region configured to accept a component of the electrical distribution system, and a first door and a second door positioned side by side to cover an open front portion of the cabinet body. The cabinet body includes at least one opening configured to accept an electrode sealed with and electrically isolated from the cabinet body and extending through the cabinet body to establish electrical connection between a corresponding terminal of the component and an electrical distribution network. A gasket system is provided, which comprises a first gasket configured to fit on the first door and a second gasket configured to fit on the second door. The gasket system seals the first door and the second door against each other and against a corresponding surface on the cabinet body, when the first and second doors are closed and locked, so that the housing is water tight.

A cooling system for an air insulated switchgear compartment includes: a housing; a fan; and a flap. The fan is mounted to the housing. The flap is mounted to the housing. The flap is positioned adjacent to the fan such that a rotational axis of the fan does not extend through the flap.

A switchgear enclosure is provided. The switchgear enclosure includes a plurality of switchgear panels and a plurality of ducts extending through the switchgear panels. Each switchgear panel includes an exterior housing, a busbar compartment defined within the exterior housing, and an exhaust system. The busbar compartment surrounds a busbar extending through the switchgear panel. The exhaust system includes a vent path structure configured within the exterior housing to at least partially surround the busbar compartment, a first channel defined between the vent path structure and the exterior housing, and a first vent opening formed on the vent path structure. The first vent opening directs arc gases within said busbar compartment to the first channel. The ducts are in fluid communication with the first channels of the switchgear panels to distribute arc gases between the first channels.
