Abstract
L'invention concerne un dispositif de protection contre les surpressions qui est incorporé à un appareil électrique à induction refroidi par vaporisation. Un dispositif sensible à la pression est prévu pour détecter la pression dans l'enveloppe hermétique contenant l'appareil et pour arrêter l'alimentation de fluide diélectrique vaporisable lorsque la pression atteint un niveau prédéterminé. Le dispositif de protection contre les surpressions réagit rapidement, lorsque le niveau de pression donnée est atteint, afin de protéger l'enveloppe hermétique contre toute rupture.
