Description
Przedmiotem wynalazku jest uklad do wytwa¬ rzania impulsów sterujacych dla trójfazowego mostkowego pelnosterowainego przeksztaltnika ty¬ rystorowego, który wymaga jednoczesnego wy¬ zwalania dwóch tyrystorów z komutacja co 60° elektrycznych.The present invention relates to a manufacturing system generating control pulses for three-phase bridge-type full-sterilized rear converter ristor, which requires simultaneous operation releasing two thyristors with commutation every 60 ° electric.
Do wytwarzania impulsów sterujacych sa sto¬ sowane uklady, sumujace logicznie wytwarzane co 60° elektrycznych sygnaly wyjsciowe szesciu czlonów sterowania liniowego, przy czyim sygna¬ ly (te sa pojedynczymi impulsami szpilkowymi, przeznaczonymi wprost do wyzwalania tyrysto¬ rów ipoprzeiz transformatory zaplonowe. Poniewaz w czasie trwania krótkiego impulsu szpilkowego zaplon pary tyrystorów moze nie nastapic, jest to przyczyna powstawania zaklócen w pracy przeksztaltników i obnizania niezawodnosci urza¬ dzen.A table is used to generate the control pulses well-suited systems that summarize logically produced every 60 ° electrical output signals six elements of linear control, with whose signal ly (these are single pin pulses, intended directly for the release of thyristo trench and pass ignition transformers. Because during the short spike pulse ignition of the thyristor pair may not occur, it is this is the cause of operational disturbances transformers and reducing the reliability of the equipment day.
Celem wynialaizkiu jest wyeliminowanie zakló¬ cen w pracy przeksztaltników, .powodowanych spo¬ sobem sterowania impulsowego. iCel ten osiagnieto' przez zastosowanie no ste¬ rowania trójfazowego mostkowego pelnosterowa- nego przeksztaltnika tyrystorowego znanego w za¬ stosowaniu do innych ukladów tyryistorowych sterowania paczkami impulsów, co zrealizowano poprzez zastapienie czlonów sterowania liniowego z wyjsciem jednoimpulsowym pólokresowymi ste¬ rownikami tyrystorów o kacie sterowania 18Q° z wyjsciem wieiloim,pulsowym, zsynchronizowany- mi w fazie i przeciwfazie z napieciami miedzy- przewodowymi sieci zasilajacej), co zapewnia wza¬ jemne przesuniecie paczek ich impulsów wyjscio¬ wych o 60° elektrycznych.The purpose of the derivation is to eliminate interference prices in the work of transformers, caused by together with impulse control. This aim has been achieved by the application of the method three-phase bridge abdominal of a thyristor converter known in the invention application to other thyristor systems control of pulse packets, which was realized by replacing the linear control elements with a single-pulse half-wave output thyristor equators with a control angle of 18 ° C with multi, pulse, synchronized output in phase and in counter-phase with inter- wires of the power network), which provides a pleasant shift of the packets of their impulses out 60 ° electric.
Efektem dokonania wynalazku jest podwyzsze¬ nie niezawodnosci przeksztaltników tyryistoro¬ wych, a ponadto mozliwosc uzycia do sterowania trójfazowych mostkowych pelnosterowanych prze¬ ksztaltników tyrystorowych opanowanych produk¬ cyjnie sterowników pólokr esowych,, równiez scalo¬ nych.The invention has the effect of increasing not the reliability of thyristor converters and the possibility of using it for control three-phase, bridge-controlled, fully-controlled thyristor shapes mastered by products semicircular drivers, also merged all.
Przyjkladowe rozwiazanie ukladu wedlug wy¬ nalazku przedstawia rysunek. Paczki impulsów wyjsciowych pólokiresowych sterowników tyrysto¬ rów 1 sa w znanym porzadku sumowane logicz¬ nie czlonami sumowania 2, z których kazdy for¬ muje sygnal wyzwalajacy dla jednego tyrystora.Sample arrangement according to excl the invention is shown in the drawing. Pulse packets output thyristor half-cycle drivers 1 are logically summed in the known order not members of the summation 2, each form of which has a trigger signal for one thyristor.
Sterowniki 1 sa synchronizowane przy pomocy napiec pomocniczych Uj+Ug, z napieciami mie¬ dzyprzewodowymi sieci zasilajacej w fazie i prze- ciwfazie. O szerokosci paczek impulsów wyjscio¬ wych decyduje napiecie sterujace Us.Drivers 1 are synchronized with of auxiliary voltage Uj + Ug, with mains voltage lines of the supply network in phase and wire c in phase. The width of the output pulse packets are determined by the control voltage Us.
Czlony sumujace 2 sumuja paczki impulsów wyjsciowych sterowników 1 tak, ze kazdy czlon 2 otrzymuje sterowanie z dwóch sterowników 1 i kazdy sterownik. 1 dostarcza impulsów do ste¬ rowania dwóch czlonów sumowania 2, z tym, ze paczki impulsów wyjsciowych sterowników 1, sterujacych jeden czlon sumowania 2 sa przesu¬ niete wzgledem siebie o kat 60° elektrycznyich. 104 397104 397 3 Skutkiem tego kazdy tyrystor j-est przy kajtach sterowania mniejszych od 60° isterowany dwoma paczkami impulsów przesunietymi o 60°, a przy wiekszych kaitaich sterowania — jedna paczka, gdyz poczynajac od 60° obie paczki zostaja na siebie nalozone. Maksymalnai szerokosc paczki impulsów do jednego tyrystora wynosi 240° elek¬ trycznych.Summing members 2 sum up the pulse packets output drivers 1 so that each 2 receives control from two controllers 1 and each driver. 1 provides pulses to the ste equating two terms of summation 2, with the proviso that driver output pulse packages 1, controlling one summation member 2 are shifted not in relation to each other with an electrical angle of 60 °. 104 397 104 397 3 Hence, each thyristor is near kites control less than 60 ° and controlled by two pulse packets shifted by 60 °, and at larger control kaitaich - one pack, for, starting from 60 °, both packages stay on self imposed. Maximum package width pulses to one thyristor is 240 ° el tric.
Uklad moze byc bez zadnych zmian stosowany do sterowania przeksztaltników pradu przemien¬ nego i stalego, równiez z oddawaniem energii do sieci zasilajacej. Zmianie ulega jedynie polozenie sterowanego z okreslonego czlona sumujacego ty¬ rystora w ukladzie przeksztaltnika. Po zmianie porzadku sumowania logicznego uklad moze byc stosowany do sterowania przeksizfcaltników,, budo¬ wanych na triakach lub simistorach. 1 m^7 T5 ^ _T5 Tr LZGraf. Z-4 iNr 2 — 1218/79 110 egz.
