The present disclosure relates to an arc ventilation system of a distributing board, and more particularly, to an arc ventilation system of a distributing board to minimize an arc flowing forward to prevent damage. In the arc ventilation system of a distributing board in which a plurality of compartments are provided, a first compartment accommodating an electric power device which can be drawn in or out, among the plurality of compartments, comprises an arc blocking part blocking a space between the electric power device and the first compartment at an operation position of the electric power device.

A power distribution cabinet is disclosed which includes multiple internal compartments for separating and channeling hot air generated by high heat generating components out of the cabinet without coming into contact with more heat sensitive components. The cabinet includes a baffle structure which forms an internal wall within the cabinet, which helps to form a high heat compartment and an upper compartment. The high heat compartment houses a heat generating component. Cool air is allowed to flow into a lower area of the cabinet and into the high heat compartment, and is also channeled into the upper compartment where at least one other heat generating component is located. The baffle structure channels hot air formed within the high heat compartment out toward a rear area of the equipment cabinet, while also helping to channel warm air created within the upper compartment through a top panel of the cabinet.

A low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure and/or one of said compartments with a second compartment. The venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition at first predetermined temperatures and the enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition at second predetermined temperatures. The actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at said first predetermined temperatures reversibly changeable into a second dimension at said second predetermined temperatures, the reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determining the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.

A multi-function cabinet housing electrical equipment. The multi-function cabinet has four compartments. Each compartment is configured to house a different type of electrical equipment. The electrical equipment may be high-voltage electrical metering and distribution components, high-voltage control electronics, battery backup, wireways, low-voltage electronics, or a combination thereof. The multi-function cabinet contains wireways. The compartments of the multifunction cabinet are accessible using doors, which are fastened by locks. The cabinet contains a ventilation system with fans, vents, and filters.

An airflow management system that can be fitted to an electrical cabinet intended to accommodate electrical devices in the internal volume thereof, the system comprising: a casing comprising at least one air input intended to be placed in communication with the internal volume of the electrical cabinet, at least two air outputs and at least one principal throat arranged to connect the air input to the two air outputs, a switch device arranged inside said principal throat, between the first air output and the second air output, the switch device comprising movable flaps that can be controlled between a first position in which the air input communicates solely with the first air output and a second position in which the air input communicates at least with the second air output.

An uninterruptible power supply device includes a housing having a rectangular parallelepiped shape, a plurality of units vertically stacked and accommodated in housing, and a fan unit having a plurality of fans aligned on an upper surface of housing. Each of the upper surface and the lower surface of housing is formed with an opening through which a wire is led into housing.

An electrical equipment cabinet includes a plurality of walls defining an interior of the electrical equipment cabinet, a battery carrier positionable within the interior of the electrical equipment cabinet, and a plurality of batteries attached to the battery carrier via adhesive to substantially prevent removal of the plurality of batteries from the battery carrier. Other example electrical equipment cabinets, battery carriers, etc. are also disclosed.

A noise reduction assembly includes an outer frame and a partition plate. An accommodating cavity is arranged in the outer frame; the partition plate is arranged in the accommodating cavity, and the partition plate and the outer frame form a noise reduction channel, the noise reduction channel includes a first noise reduction section, a second noise reduction section and a third noise reduction section that are communicated in sequence, and the channel cross-sectional areas of the first noise reduction section and the third noise reduction section are both smaller than the channel cross-sectional area of the second noise reduction section. The technical solution of the present application may reduce the noise of a new energy equipment having the noise reduction assembly during operation.

An arrangement for subsea cooling of a semiconductor module. The arrangement includes a tank. The tank is filled with a dielectric fluid. The arrangement includes at least one semiconductor module. The at least one semiconductor module is placed in the tank. Each at least one semiconductor module includes semiconductor submodules and is attached to a heat sink. The semiconductor submodules generate heat, thereby causing the dielectric fluid to circulate by natural convection. The heat sink includes a first part having a first thermal resistance from the semiconductor module to the dielectric fluid. The heat sink includes a second part having a second thermal resistance from the semiconductor module to the dielectric fluid. The second thermal resistance is higher than the first thermal resistance. The heat sink is oriented such that, when the arrangement is installed, the first part is configured to lie vertically higher than the second part.
