Abstract
Inventia se refera la un dispozitiv pentru conectarea si deconectarea automata a instalatiilor de sudare electrica avînd în structura un contactor de cuplare a alimentarii instalatiei de sudura, un transformator auxiliar cu o înfasurare secundara, pentru alimentarea circuitelor de comanda si o înfasurare secundara, destinata furnizarii curentului pentru sesizarea contactului electrod-piesa, dispozitiv caracterizat prin aceea ca sesizarea prezentei unui curent alternativ sau continuu în circuitul de sudura se face prin intermediul unui traductor de curent format dintr-un miez feromagnetic toroidal avînd un întrefier, în care se introduce un senzor de tip Hall integrat.The invention relates to a device for the automatic connection and disconnection of the electrical welding installations having in the structure a welding power supply coupling contactor, an auxiliary transformer with a secondary winding for supplying the control circuits and a secondary winding for supplying the current for sensing the electrode-piece contact, characterized in that the sensing of the presence of an alternating or continuous current in the welding circuit is made by means of a current transducer formed by a toroidal ferromagnetic core having an air gap in which a type sensor Hall integrated.
