Abstract

Dispozitivul pentru limitarea mersului an gol la dintr-un comutator automat "stea-triunghi", în componenta caruia intra un contactor pentru realizarea conexiunii în "stea" a motorului de antrenare si un contactor pentru conexiunea "triunghi" si care este comandat prin intermediul unei bobine de comanda saturabila si a unei punti redresoare, la prima atingere a electrodului de piesa si care dispozitiv mai are în componenta un releu având atât functia de releu de tensiune, cât si functia de releu de timp, fiind prevazut cu niste contacte si temporizat printr-un circuit de tip RC, prin care se realizeaza trecerea motorului de la schema "stea" la schema "triunghi" cât si dintr-un contact temporizat penumatic, prin care se realizeaza întreruperea functionarii convertizorului la functionarea în gol.The device for limiting naked driving from a "star-triangle" automatic switch, comprising a contactor for the "star" connection of the drive motor and a "triangle" contactor, which is commanded by means of a saturable control coils and a rectifier bridge at the first touch of the piece electrode, and which device further comprises a relay having both the relay function and the relay function, being provided with some contacts and timed by - an RC circuit, which allows the motor to pass from the "star" scheme to the "triangle" scheme and from a timed penumatic contact, which causes the inverter to stop working when empty.
