Abstract
Dispozitivul, conform inventiei, este destinat aprinderii lampilor cu xenon, de mare putere, utilizate la procesele de fotoreproducere si este constituit dintr-un starter electronic care contine un condensator alimentat direct de la reteaua de curent alternativ. Condensatorul se încarca în serie, prin primarul unui tranformator ridicator si un triac, dând un impuls de tensiune înalta de la secundarul transformatorului la una sau doua lampi cu xenon X. Tensiunea înalta poate fi reglata prin reglarea defazajului tensiunii de poarta fata de anodul triacului, cu ajutorul unei rezistente reglabile legata de triac prin intermediul unui diac si unui condensator. Impulsurile de tensiune înalta sunt declansate în momentul în care condensatorul deschide diacul si apare o tensiune care declanseaza deschiderea triacului prin poarta sa. Aceste impulsuri se repeta în ritmul frecventei curentului alternativ de la retea, atât pe alternanta pozitiva cât si pe cea negativa, la valoarea maxima a curentului pâba când un contact este deschis prin comanda unui montaj electronic de timp, care pe durata expunerii fotografice si a functionarii lampii, mentine închis acest contact. Ciclul poate fi reluat imediat printr-un nou start. La secundarul transformatorului se pot lega una sau doua lampi cu xenon, pentru un numar mai mare de lampi, crescând numarul de transformatoare în raportul 1:2.The device according to the invention is designed to ignite the high-powered xenon lamps used in photoproduction processes and consists of an electronic starter containing a capacitor powered directly from the AC network. The capacitor is charging in series via the canal of a lift transformer and a triac, giving a high voltage pulse from the transformer's secondary to one or two xenon lamps X. High voltage can be adjusted by adjusting the phase voltage of the gate to the triode anode, with the help of an adjustable resistor connected to the triac via a diac and a capacitor. High-voltage pulses are triggered when the capacitor opens the glow and a voltage arises triggering the triac opening through its gate. These pulses are repeated in the frequency of the alternating current frequency of the network, both on the positive and negative alternations, at the maximum value of the current, when a contact is open by command of an electronic time assembling, which during the photographic exposure and the operation lamps, keep this contact closed. The cycle can be resumed immediately by a new start. Two or more xenon lamps can be connected to the transformer secondary for a larger number of lamps, increasing the number of transformers in the 1: 2 ratio.
