Description
Przedmiotem wynalazku jest miernik szybkosci zmian mocy reaktora jadrowego, samoczynnie wybierajacy sygnaly pochodzace z dwóch logarytmicznych torów pomiarowych, znajdujacy zastosowanie w ukladach kontroli reaktora jadrowego, a szczególnie w impulsowo-pradowych liniach rozruchowych.The subject of the invention is a measure of the rate of change of power of a nuclear reactor, self-selecting signals coming from two logarithmic measurement paths, used in systems nuclear reactor control, especially in pulse-current start-up lines.
Stan techniki. Znany jest z referatu A.Krzyckiego, A.Ostrowskiego i A.Janikowskiego: Szerokozakresowa impulsowo-pradowa linia pomiarowa ILR-5 do kontroli rozruchu i przeladunku paliwa w reaktorach typu WWER nr 2-33/4-10 z konferencji: Kontrola i sterowanie reaktorami jadrowymi i elektrowniami jadrowymi Warszawa (1973 r.) uklad w którym jeden okresomierz jest przylaczony recznie do wyjsc oddzielnych torów pomiaro¬ wych. Wada ukladu jest wystepujacy skok sygnalu na wyjsciu o kresomierza, wynikajacy z jego dolaczenia do róznych poziomów napiec wejsciowych.State of the art. He is known from the report by A. Krzycki, A. Ostrowski and A. Janikowski: Wide range impulse-current measurement line ILR-5 for start-up control and fuel reloading in VVER type reactors No. 2-33 / 4-10 from the conference: Control and control of nuclear reactors and nuclear power plants, Warsaw (1973) a system in which one periodometer is manually connected to the outputs of separate measurement paths out. The defect of the system is the jump of the signal at the output of the gauge, resulting from its connection to different input voltage levels.
Inny uklad opisany przez H.A.Thomas'a i A.C.Mc Bride'a - IEEE Transactions of Nuclear Sciences, June (1969) zawiera okresomierz pracujacy od jednego sygnalu pochodzacego od wczesniejszego sumowania dwu sygnalów logarytmicznych. Wada ukladu jest to, ze precyzja odpowiedzi okresomierza zalezy od zestrojenia charakterystyk i stabilnosci poprzednich ukladów.Another system described by H.A. Thomas and A.C. Mc Bride - IEEE Transactions of Nuclear Sciences, June (1969) includes a periodometer operating from one signal derived from an earlier summation of two logarithmic signals. The drawback of the circuit is that the precision of the periodometer response is dependent on the alignment characteristics and stability of previous systems.
Istota wynalazku. Miernik szybkosci zmian mocy reaktora jadrowego sklada sie z ukladu wybierania torów pomiarowych sterowanego za pomoca ukladu progowego, polaczonego z operacyjnym wzmacniaczem rózniczku¬ jacym. Dwa kondensatory dolaczone sa jednymi okladzinami do wyjsc dwóch torów pomiarowych, a drugimi okladzinami do przelaczników, które lacza kondensatory na przemian z rezystorem szeregowym dolaczonym do wejscia wzmacniacza elektrometrycznego i z rezystorem rozladowujacym. Aktualnie odlaczona od rezystora szeregowego okladzina kondensatora jest polaczona poprzez rezystor rozladowujacy punktu o potencjale zero woltów.The essence of the invention. The rate of change in the power of a nuclear reactor consists of a track selection system controlled by a threshold circuit connected to an operational amplifier of the differential Jacym. Two capacitors are connected with one cladding to the outputs of the two measuring circuits, and the other cladding for the switches that connect the capacitors alternately with the series resistor attached to the electrometric amplifier inputs and with a discharge resistor. Currently disconnected from the resistor The series capacitor lining is connected via a zero potential point discharge resistor volts.
Korzystne skutki wynalazku. Zaleta wynalazku jest uzyskanie jednego sygnalu charakteryzujacego okres reaktora przy uniknieciu nieciaglosci zwiazanych z przelaczaniem torów pomiarowych. Zastosowanie automa¬ tycznego przelaczania pozwala na uproszczenie obslugi i unikniecie falszywych pomiarów. Z prostoty ukladu wynika niezawodnosc urzadzenia, wymagana dla zastosowan w ukladach kontroli reaktora jadrowego.2 101 616 Objasnienie rysunku. Przedmiot wynalazku jest pokazany na przykladzie wykonania, odtworzonym na rysunku, przedstawiajacym funkcjonalny schemat polaczen.Advantageous Effects of the Invention. The advantage of the invention is to obtain a single signal that characterizes the period reactor while avoiding discontinuities related to switching measurement paths. The use of automatic the tactile switching allows to simplify the operation and avoid false measurements. From the simplicity of the layout shows the reliability of the device, required for applications in nuclear reactor control systems. 2 101 616 Explanation of the drawing. The subject matter of the invention is shown in the embodiment reproduced in a drawing showing a functional connection diagram.
Przyklad wykonania. Kondensator 1, dolaczony do wyjscia podajacego napiecia z jednego z logarytmicz¬ nych torów pomiarowych Vi, przylaczony jest druga okladzina poprzez przelacznik 4 oraz rezystor szeregowy 9 do wejscia wzmacniacza elektrometrycznego 6 z rezystorem sprzezenia 7, z którym stanowi uklad rózniczkujacy.Execution example. Capacitor 1, connected to the output feeding voltage from one of the logarithmic measurement paths Vi, a second cladding is connected through a switch 4 and a series resistor 9 to the input of an electrometric amplifier 6 with a coupling resistor 7, with which it constitutes the differential.
Rezystor szeregowy 9 wraz z pojemnoscia 10 decyduja o czasie narastania ukladu. Drugi identyczny kondensator 2, dolaczony do wyjscia podajacego napiecie drugiego toru pomiarowego Va przylaczony jest druga swa okladzina poprzez przelacznik 5 sprzezony z przelacznikiem 4 oraz rezystor rozladowujacy 3 do punktu o potencjale zero woltów. Przelaczniki 4 i 5 sterowane sa przez uklad progowy 8, który moze byc uzalezniony od poziomu mierzonej mocy np. od jednego z napiec z torów pomiarowych Vi albo V3 lub sterowany recznie.The series resistor 9 together with the capacitance 10 determine the rise time of the system. Second identical capacitor 2, connected to the output supplying voltage of the second measurement line Va, the second cladding through switch 5 connected to switch 4 and discharge resistor 3 to the point of zero volt potential. Switches 4 and 5 are controlled by a threshold circuit 8 which may be dependent on measured power level, e.g. from one of the voltages from measuring lines Vi or V3 or manually controlled.
Dokonuja one zamiany kondensatora na wejsciu ukladu rózniczkujacego. Oba identyczne kondensatory 1 i 2 dolaczone sa swymi okladzinami do wspólbieznych napiec z torów pomiarowych Vi i V3 reprezentujacych moc reaktora w skali logarytmicznej i dlatego tez po przelaczeniu prad dostarczony do rezystora sprzezenia 7 nie ulega zmianie. W efekcie na wyjsciu wzmacniacza 6 otrzymuje sie sygnal napieciowy reprezentujacy szybkosc zmian sygnalów Vi lub V2 czyli odwrotnosc okresu reaktora jadrowego.They replace the capacitor at the input of the differential. Both identical capacitors 1 and 2 with their linings, they are attached to the common voltages from the measurement paths Vi and V3 representing the power reactor on a logarithmic scale and therefore after switching the current supplied to the feedback resistor 7 does not is changing. As a result, at the output of the amplifier 6, a voltage signal is obtained representing the speed changes in Vi or V2 signals, ie the reciprocal of the nuclear reactor period.
