    Abstract: A cabinet comprising an outer wall which encapsulates an internal space comprising electronic components, the outer wall having a rupture line forming a release wall portion which by rupturing of the rupture line in response to an increased pressure in the internal space can be released and thereby define an opening forming arc-vent for the internal space. To protect against penetration of objects of a predetermined size into the electronic components,the cabinet further comprises a ventilation-open inner lining arranged in the internal space to cover the opening. If arching should occur, the increased pressure may rupture the line and the opening will allow venting. In this situation, the inner lining prevents against penetration.

    Abstract: A system for a wind turbine, comprising a generator (28) connected to a power converter (30) by an electrical connection (32), a circuit breaker system (69) controlling the connection between the generator and the power converter through the electrical connection, and a sensor system (66) configured to sense operational parameters, wherein the generator is a permanent magnet generator. The system further comprises a protection system (61) interfaced to the circuit breaker system and the sensing system. The protection system is configured to determine an operational mode of the wind turbine (102) by monitoring at least two parameters of: the speed of the generator, the operational status of the power converter, and the operational status of the circuit breaker system, and defining an operational mode based on the monitored parameters, determine a parameter set comprising a plurality of operational parameters (104) based on the determined operational mode, and an associated set of expected values corresponding to the parameter set, wherein the determined parameter set includes generator voltage and generator speed, determine actual values corresponding to the determined parameter set (108), identify a fault condition in the event that the determined set of actual values of the operational parameters do not correspond to the determined set of expected values of the operational parameters, and implement a protection action based on the identified fault condition.

    Abstract: A cabinet for electronic components, the cabinet comprising an outer wall, a closure, and an attachment structure, the outer wall encapsulating an internal space and forming an opening, the closure being attached to the outer wall by the attachment structure, and the attachment structure allowing movement of the closure relative to the outer wall between an open position where the opening is uncovered and a closed position where the opening is covered by the closure. To enable automatic and fast opening of the cabinet in case of over pressure, e.g. caused by arching of electronic components in the cabinet, the cabinet further comprises a magnet structure comprising at least one magnet arranged to hold the closure in the closed position and to release the closure in response to a pressure in the internal space.
