Abstract
Zestaw do pomiarów momentów maszyny elektrycznej prądu przemiennego, charakteryzuje się tym, że do osłony wentylatora maszyny elektrycznej (1), z zachowaniem dystansu dla przepływu powietrza, przymocowana jest cewka (2) połączona z układem kondycjonowania sygnału (3) połączonym z przestrajalnym filtrem dolnoprzepustowym (4), połączonym z układem formowania sygnału prostokątnego z punktów przejścia sygnału przez zero (5), korzystnie w postaci przerzutnika, połączonego z układem różniczkującym (6), który połączony jest z programowalnym układem mikroprocesorowym (8), przy czym do przestrajalnego filtru dolnoprzepustowego (4) dołączony jest wielopozycyjny przełącznik pojemności (7), przy czym sygnał z programowalnego układu mikroprocesorowego (8) doprowadzony jest do złącza analogowego i cyfrowego (10) lub doprowadzony jest do wyświetlacza (11) lub sygnał doprowadzony jest do modułu komunikacji sieciowej (12). W drugiej wersji rozwiązania filtr dolnoprzepustowy (4), połączony jest z przetwornikiem A/D (9), który połączony jest z programowalnym układem mikroprocesorowym (8), przy czym do przestrajalnego filtru dolnoprzepustowego (4) dołączony jest wielopozycyjny przełącznik pojemności (7), przy czym sygnał z programowalnego układu mikroprocesorowego (8) doprowadzony jest do złącza analogowego i cyfrowego (10) lub doprowadzony jest do wyświetlacza (11) lub sygnał doprowadzony jest do modułu komunikacji sieciowej (12).The set for measuring the moments of the AC electric machine is characterized by the fact that a coil (2) connected to the signal conditioning system (3) connected with the tunable low-pass filter ( 4), connected to a square wave signal shaper from the zero crossing points (5), preferably in the form of a trigger, connected to a differentiator (6), which is connected to a programmable microprocessor circuit (8), to a tunable low-pass filter ( 4) a multi-position capacity switch (7) is attached, and the signal from the programmable microprocessor circuit (8) is fed to the analog and digital connectors (10) or is fed to the display (11) or the signal is fed to the network communication module (12) . In the second version of the solution, the low-pass filter (4) is connected to the A / D converter (9), which is connected to a programmable microprocessor system (8), while the tunable low-pass filter (4) has a multi-position capacity switch (7), wherein the signal from the programmable microprocessor circuit (8) is fed to the analog and digital connectors (10) or is fed to the display (11) or the signal is fed to the network communication module (12).
