摘要： The invention relates to a circuit breaker, which is in a fault situation arranged to disconnect an electrical apparatus, such as a distribution transformer, from an average voltage network or a high voltage network at each terminal. At least one lik-spring mechanism (9 to 12) is arranged at a shaft (6) of the circuit breaker for holding contacts (1, 2) live in connected position and for pushing them apart to the extreme disconnected position when disconnected, while the shaft (6) is brought over the dead spot of its turning. For an initial release, the shaft (6) is at each phase provided with a lever arm (8), each lever arm at each phase being arranged to turn by means of a trip pin (19) of a striker (18) of a high voltage fuse (17) the shaft (6) of the circuit breaker and thus the moving contacts (1) of all phases from said connected position over the dead spot of turning said shaft.

摘要： The invention relates to a transformer designed especially for underwater use, which transformer comprises a transformer core (1) and its winding located in a first container (2) filled with an insulating medium (3), the top surface of which container is provided with pressure-proof bushings (9, 10) for the connecting cables (12) of the transformer, a second container (4) filled with an insulating medium (5) and means (8) for equalising the pressure between the insulating medium (5) in the second container (4) and the transformer surroundings. According to the invention the second container (4) is arranged to completely encompass the first container (2) and the second container (4) is equipped with pressure-proof cable bushings (13) and associated connectors for external electrical connections of the transformer.
