Abstract

Inventia se refera la un dispozitiv de protectie împotriva electrocutarii la transformatoarele de sudare, format dintr-un generator de impulsuri ce alimenteaza o bobina ce induce un curent în circuitul de sudare, când este închis si impulsuri într-o a doua bobina, conectata în continuare cu un amplificator, acesta fiind legat cu un detector de impulsuri ce comanda conectarea transformatorului de sudura la retea în prezenta impulsurilor printr-un etaj final de actionare. Elementele dispozitivului sunt alimentate de la un bloc de alimentare , iar un întrerupator conectat între sursa si retea da posibilitatea scoaterii din functiune atât a transformatorului cât si a dispozitivului de protectie.The invention relates to a device for protecting against electrocution at welding transformers consisting of a pulse generator which supplies a coil which induces a current in the welding circuit when impulses are closed in a second coil further connected with an amplifier, this being connected to a pulse detector which controls the connection of the welding transformer to the network in the presence of impulses through a final stage of action. The device elements are powered by a power supply unit, and a switch connected between the power supply and the network enables the transformer and the protection device to be deactivated.
