SYSTEM OF PROTECTION AGAINST SHORT CIRCUITS AND FULMINATIONS

摘要

The present invention provides a system of protection against electric current, short circuits and explosions, able to be used with any installation comprising an electric apparatus and a polyphase feed cable connecting the apparatus to a socket through a connection such as a conventional plug. According to the invention, the installation comprises a screening of the electric apparatus and/or of the feeding cable, formed by a pair of spaced wire nets electrically insulated one from the other. There is two-phase electric line with each phase connected to one of the wire nets. A cutout circuit is associated with the connection means for disconnecting the electric feed in response to a short circuit between the two wire nets.
