Description
Do prób zwarciowych, np. podczas badania bezpieczników, styczników itp., potrzebny jest czlonk wlaczajacy lub wylaczajacy uklad elek¬ tryczny w chwili, gdy napiecie zmienne posiada okreslona faze.W mysl wynalazku stosuje sie do tego celu uklad, uwidoczniony na rysunku. Sklada sie on z przesuwnika fazowego P, transformatora im¬ pulsowego Tr oraz tyratronu wyzwalajacego T.Zasada dzialania ukladu jest opisana ponizej.Poniewaz transformator impulsowy Tr daje ostre impulsy napiecia z chwila, gdy zasilajace go napiecie przechodzi przez zero, przeto zmie¬ niajac faze tego napiecia za pomoca przesuw¬ nika fazowego P mozna zmieniac moment, w którym tyratron T zadziala.Aby zaplon tyratronu nastapil w odpowied¬ nim momencie, tyratron jest blokowany napie¬ ciem czynnym w jego obwodzie siatkowym. Po odblokowaniu tyratronu np. przez zwarcie klu¬ cza K pierwszy dodatni impuls powoduje za¬ dzialanie tyratronu. PLFor short-circuit tests, e.g. when testing fuses, contactors, etc., a device is needed to switch the electrical system on or off when the alternating voltage has a certain phase. The invention uses the circuit shown in the figure for this purpose. It consists of a phase shifter P, a pulse transformer Tr and a tripping thyratron T. The principle of the circuit is described below, because the pulse transformer Tr gives sharp voltage pulses as soon as the voltage supplying it passes through zero, thus changing the phase of this In order to ignite the thyratron at the right moment, the thyratron is blocked by an active voltage in its grid circuit. After the thyratron is unblocked, for example by short-circuiting the K key, the first positive impulse causes the thyratron to act. PL
