Abstract

A static electrical device assembly comprises a static electrical device (2); a heat exchanger system comprising a first heat exchanger (41) adapted for cooling of the static electrical device (2) by transferring heat into ambient air, and a second heat exchanger (42) adapted for recovering heat from the static electrical device (2); a flow passage (6) adapted to provide a route for air flow between outdoor air and the first heat exchanger (41); a sensor system adapted to provide temperature information relating to the static electrical device (2); and a control system (CTRL) adapted to control the heat exchanger system based on information provided by the sensor system. The heat exchanger system further comprises a shutter arrangement (8) adapted to adjust a surface area of the flow passage (6), and the control system (CTRL) is adapted to control the shutter arrangement (8) between an open state and an enclosed state.

Description

technical field [0001] The present invention relates to an electrostatic device assembly comprising an electrostatic device, a first heat exchanger adapted to cool the electrostatic device, and a second heat exchanger adapted to recover heat from the electrostatic device for utilization. Electrostatic devices here include transformers or inductors. Background technique [0002] It is known in the art to provide an electrostatic device assembly with an adjustable cooling pump adapted to transfer coolant between the electrostatic device and the first heat exchanger and / or to provide an air flow between the outdoor air and the first heat exchanger The cooling fan can be adjusted to regulate the cooling of the electrostatic device. [0003] One of the disadvantages associated with the electrostatic device assembly described above is that the adjustable cooling pump and / or adjustable cooling fan make the electrostatic device assembly a complex and expensive assembly and the cool...
