Abstract

Inventia se refera la un dispozitiv de conectare si deconectare a alimentarii convertizoarelor rotative pentru sudare manuala cu arc electric avînd în structura un mutator trifazat cu tiristori, un dispozitiv de comanda pe grila, un bloc electronic amplificator de mentinere comanda si formare tensiune liniar variabila, un bloc sesizor si un bloc de alimentare, caracterizat prin aceea ca, în scopul obtinerii unei variatii liniare pentru tensiunea de alimentare a motorului convertizorului, mutatorul este comandat automat prin variatia liniara a tensiunii de comanda de iesire a blocului electronic amplificator de mentinere comanda, si formare tensiune liniar variabila, datorita semnalului obtinut din blocul sesizor, în scopul realizarii unei comenzi sigure, pe tiristorii mutatorului modulîndu-se impulsurile generate de niste circuite integrate cu impulsuri de frecventa ridicata, generate de un circuit astabil.The invention relates to a device for connecting and disconnecting the power supply of rotary converters for manual arc welding having in the structure a three-phase thyristor mutator, a grid control device, an electronic block of control voltage and variable voltage a sinker block and a power supply unit, characterized in that in order to obtain a linear variation of the supply voltage of the converter motor, the mutable is automatically controlled by the linear voltage variation of the output control of the electronic block of the control unit, variable linear voltage, due to the signal obtained from the sinker block, in order to achieve a safe command, on the muting thyristors modulating the impulses generated by some integrated circuits with high frequency pulses generated by an astable circuit.
