An arc-resistant switchgear enclosure has interior compartments with outlet vent openings that are selectively closed by vent flaps. The vent flaps are propped in an open position by props that extend from the vent flaps and contact supports. The props have a latch portion that latches the vent flap when the vent flap is in the closed position.

The invention relates to a heating device for installation in a switchgear cabinet, having a support and a heating body, wherein the support replaceably accommodates the heating body in a holder. Simple and secure mounting of the heating body on the support is achieved in that the holder has a contact surface to which limiting elements are attached, in that the limiting elements immobilize the heating body in a form-fitting manner transversely to the contact surface plane, and in that one or a plurality of locking elements are provided in the region of the holder, which immobilize the heating body in a form-fitting manner perpendicularly to the contact surface.

The invention relates to a busbar pack comprising n busbars (2) and at least n-1 insulating bars (4) the surfaces of which project beyond the busbars (2), one insulating bar (4) being interposed between two busbars (2), said stack of bars (2, 4) being immobilized in their position relative each other by devices. The invention is characterized in that at least one inner busbar (2) is provided with a reticular bar (6) on both sides thereof and has perforations (14) that are arranged to match crossbars (12) of corresponding reticular bars (6). The invention allows production of a busbar pack at least the inner busbar (2) of which is convection-cooled, said busbar cooling system being producible at low costs.

An electrical distribution apparatus configured to connect a load to a power source is disclosed. The apparatus includes a housing having an air inlet and an air outlet, a distribution conduction path, a thermal sensor in thermal communication with the conduction path, an electrical disconnect, and an airflow generator. The electrical disconnect is connected in series with the conduction path and is configured to isolate the load from the power source on command, the disconnect being in signal communication with the thermal sensor. The airflow generator is in signal communication with the thermal sensor and is arranged to cause air to flow into the air inlet and out of the air outlet. The airflow generator is configured to turn on in response to the thermal sensor sensing a first temperature, and the disconnect is configured to disconnect the load from the power source in response to the thermal sensor sensing a second temperature greater than the first temperature.

The invention relates to a switchgear cabinet air conditioning device comprising at least one cooling device (1), which has a cooling device control and an operating device connected thereto. A simple operability is attained due to fact that the operating device comprises a server (1.1), which is assigned to the cooling device control, and comprises a network connection as well as at least one personal computer (2), which is connected via said network connection and via a universally accessible network (3) and provided with an assigned web browser (2.1), by means of which the data retrieved from the server (1.1) can be visually displayed.
摘要:
A cabinet has an inner roof portion and an outer roof portion above the inner roof portion. A solar shield is above the outer roof portion. A heat exchanger has a first portion that absorbs heat. The first portion of the heat exchanger is located between the inner roof portion and the outer roof portion. The heat exchanger has a second portion that rejects heat. The second portion of the heat exchanger is located between the outer roof portion and the solar shield. The heat exchanger has a heat pipe for transferring heat between the first passage and the second passage. The heat pipe includes an evaporator that absorbs heat from the heated air and a condenser that rejects heat to the cooled air.
摘要:
A switchgear cabinet having at least one cabinet door and a fan-assisted air circulation on an interior for cooling heat-generating devices installed inside, which are disposed one above the other in tiers. With particular air circulation, the partial cooling air flows in the tiers and can be set and adjusted, to a large extent independently of one another.

A control cabinet with a frame having framing profiles and covered with side members and at least one door. The frame surrounds the inside of the control cabinet where electrical components are integrated. An air conditioning device which is placed on at least one vertical side of the frame rejects heat generated inside the control cabinet. This invention provides this type of cooling apparatus with additional equipment without the need for a large number of pieces. For this purpose, a separating member, parallel to the lateral side and placed at a distance therefrom, is attached to the framing profiles and forms with the side channel an air guiding channel. Moreover, the separating member comprises several passages for providing a physical connection between the air guiding channel and the inside of the control cabinet. Furthermore, air can be conveyed through the air guiding channel and through at least one passage by using at least one fan.
