Abstract

Dispozitiv universal pentru protectia antibifazica a motoarelor electrice trifazate caracterizat prin aceea ca este alcatuit din trei traductoare de tensiune, fiecare format dintr-un miez magnetic pe care este montat o carcasa electroizolanta pe care se gasesc plasate pe câte o înfasurare de curent realizata dintr-o singura spira înseriata cu faze care alimenteaza motorul electric, precum si câte o înfasurare de tensiune care alimenteaza câte un releu intermediar si unde contactele normal-deschis aferente celor trei relee, sunt înseriate în schema de autoretinere a unui contactor prin care se comanda alimentarea motorului electric trifazat.Universal device for antibacterial protection of three-phase electric motors, characterized in that it consists of three voltage transducers, each consisting of a magnetic core on which is mounted an insulating housing which is placed on a current drawn from a the single phase-spiraling phase that feeds the electric motor, and a voltage gauge which supplies an intermediate relay and where the normally open contacts of the three relays are connected to the self-regulating circuit of a contactor controlling the supply of the electric motor phase.
