Abstract

Zespól zawiera czwórnik, którego pierwszy zacisk wejsciowy (1) i pierwszy zacisk wyjsciowy (3) sa zwiazane miedzy soba poprzez szeregowo polaczone rezystor pomiarowy (5) i pierwszy klucz elektroniczny (6), natomiast drugi zacisk wejsciowy (2) i drugi zacisk wyjsciowy (4) sa zwiazane bezposrednio. Równolegle do zacisków wejsciowych (1 i 2) jest podlaczony uklad (12) ujemnego napiecia, natomiast do zacisków wyjsciowych (3 i 4) sa podlaczone drugi klucz elektroniczny (7) i trzeci klucz elektroniczny (8) oraz uklad (9) kontroli napiecia, którego wyjscie sterujace zwiazane jest z wejsciem sterujacym trzeciego klucza elektronicznego (8), a wejscie sterujace drugiego klucza elektronicznego (7) jest zwiazane z drugim wyjsciem sterujacym ukladu sterujacego (11). Pierwsze wyjscie sterujace ukladu sterujacego (11) jest zwiazane z wejsciem sterujacym pierwszego klucza elektronicznego (6), a drugie wejscie jest zwiazane z wyjsciem komparatora (10) pradu, którego pierwsze wejscie jest zwiazane z jednym koncem rezystora pomiarowego (5), a drugie wejscie jest zwiazane z drugim koncem tego rezystora. Zaciski zasilania komparatora (10) pradu i ukladu sterujacego (11) sa wspólnie podlaczone do ukladu (12) ujemnego napiecia.The assembly consists of a cross, the first input terminal (1) and the first output terminal (3) are connected to each other through a series connected measuring resistor (5) and the first electronic key (6), while the second input terminal (2) and the second output terminal ( 4) are directly related. Parallel to the input terminals (1 and 2) the negative voltage system (12) is connected, while the output terminals (3 and 4) are connected to the second electronic key (7) and the third electronic key (8) and the voltage control system (9), whose control output is associated with the control input of the third electronic key (8), and the control input of the second electronic key (7) is associated with the second control output of the control system (11). The first control output of the control system (11) is associated with the control input of the first electronic key (6), and the second input is associated with the output of the comparator (10) current, whose first input is associated with one end of the measuring resistor (5), and the second input is related to the second end of this resistor. The power terminals of the comparator (10) current and control system (11) are connected together to the negative voltage system (12).
