Abstract
Inventia se refera la electrotehnica, si anume la stabilizatoarele de curent si tensiune, care pot fi folosite in prelucrarea electrofizica si electrochimica. Stabilizatorul de curent contine un transformator coborator de tensiune (1), bobina primara a caruia este conectata la reteaua de tensiune variabila, la bobina secundara a caruia este conectat un redresor reglabil (2), la iesirea caruia este conectat un filtru (3), la iesirea pozitiva a caruia este conectata o sarcina (4). Stabilizatorul de curent de asemenea contine un bloc de comanda (8) a redresorului reglabil (2) si doua rezistente variabile (9, 11). Stabilizatorul de curent contine suplimentar un element-cheie (5), conectat in serie intre sarcina (4) si un sunt (6), iesirea acestuia fiind unita cu iesirea negativa a filtrului (3). Paralel elementului-cheie (5) este conectata prima rezistenta variabila (9), unita cu blocul de comanda (8) a redresorului reglabil (2), iesirile caruia sunt conectate la electrozii de comanda a tiristoarelor redresorului reglabil (2). Stabilizatorul de curent de asemenea contine un ampermetru (7) conectat paralel suntului (6) si celei de-a doua rezistente variabile (11), unita cu un bloc de stabilizare a curentului (10), iesirea caruia este conectata la elementul-cheie (5). Avantajele inventiei constau in majorarea randamentului, extinderea domeniului de aplicare, micsorarea masei si gabaritelor dispozitivului.The invention relates to electrotechnics, namely to current and voltage stabilizers, which can be used in electrophysical and electrochemical processing. The current stabilizer contains a voltage lowering transformer (1), the primary coil of which is connected to the variable voltage network, to the secondary coil of which an adjustable rectifier (2) is connected, at the output of which a filter (3) is connected, at the positive output to which a load is connected (4). The current stabilizer also contains a control block (8) of the adjustable rectifier (2) and two variable resistors (9, 11). The current stabilizer also contains a key element (5), connected in series between the load (4) and a sound (6), its output being combined with the negative output of the filter (3). Parallel to the key element (5) is connected the first variable resistor (9), coupled with the control block (8) of the adjustable rectifier (2), the outputs of which are connected to the control electrodes of the adjustable rectifier thyristors (2). The current stabilizer also contains an ammeter (7) connected parallel to the socket (6) and the second variable resistor (11), coupled with a current stabilizing block (10), the output of which is connected to the key element ( 5). The advantages of the invention consist in the increase of the efficiency, the extension of the scope, the decrease of the mass and the dimensions of the device.
