Description
Przedmiotem wynalazku jest uklad do pomiaru pola magnetycznego nalezacy do dziedziny techniki ukladów lub przyrzadów do pomiaru wielkosci magnetycznych.The present invention relates to a magnetic field measuring system belonging to technical fields of systems or instruments for measuring magnetic quantities.
Stan techniki. Znany uklad do mierzenia pola magnetycznego zawiera miernik pola, do którego podlaczony jest woltomierz napiecia stalego oraz przetwornik. Celem dokonania pomiaru uklad nalezy kazdorazowo wycechowac. Omawiany uklad jest opisany w ksiazce pt.: „High magnetic fields" New York- London, 1962 r. P. Grivet Ch. 7 „High field magnetometry".State of the art. The known magnetic field measuring system comprises a field meter to which a DC voltmeter and converter are connected. In order to measure, the system must be each time out. The discussed system is described in the book entitled: "High magnetic fields" New York- London, 1962 P. Grivet Ch. 7 "High field magnetometry".
Istota wynalazku. Istota wynalazku polega na tym, ze miernik pola otoczony jest cewka modulacyjna podlaczona do generatora o stalej amplitudzie, który polaczony jest jednoczesnie poprzez woltomierz napiecia przemiennego z przetwornikiem. Do miernika pola podlaczone sa woltomierz napiecia przemiennego oraz woltomierz napiecia stalego, który poprzez przetwornik polaczony jest z integratorem.The essence of the invention. The essence of the invention is that the field meter is surrounded by a modulation coil connected to a generator with a constant amplitude, which is connected simultaneously via a voltage voltmeter alternating with converter. An alternating voltage voltmeter and are connected to the field meter DC voltmeter, which is connected to the integrator through a converter.
Zaleta ukladu wedlug wynalazku jest to, ze miernik pola nie wymaga cechowania, a nawet moze byc nieliniowy. Wielkosc pola magnetycznego mozna wyznaczac za pomoca calkowania róznych parametrów, innych niz prad, od których zalezy mierzone natezenie pola magnetycznego, a mianowicie czas wzglednie odleglosc.An advantage of the system according to the invention is that the field meter does not require gauge, and may even be non-linear. The magnitude of the magnetic field can be determined by the integration of various and other parameters than the current on which the measured magnetic field strength depends, namely time or distance.
Objasnienie figur na rysunku. Przedmiot wynalazku jest odtworzony schematycznie w przykladzie wykonania na rysunku, który przedstawia uklad do pomiaru pola magnetycznego.Explanation of the figures in the drawing. The subject matter of the invention is schematically reproduced in the example the implementation in the drawing which shows the system for measuring the magnetic field.
Przyklad wykonania wynalazku i jego dzialanie. Pomiedzy biegunami elektromagnesu 1 znajduje sie miernik pola 2. Pomiedzy miernikiem 2 i elektromagnesem 1 umieszczona jest cewka modulacyjna 3 podlaczona do generatora 4. Do miernika 2 przylaczony jest poprzez woltomierz napiecia przemiennego 5 i woltomierz napiecia stalego 6 przetwornik 7, którego wyjscie polaczone jest z integratorem 8. Wyjscie integratora 8 jest zarazem wyjsciem ukladu.An embodiment of the invention and its operation. Between the poles of the electromagnet 1 is located field meter 2. Between the meter 2 and the electromagnet 1 there is a modulating coil 3 connected to the generator 4. The meter 2 is connected via an alternating voltage voltmeter 5 and a voltmeter DC voltage 6 converter 7, the output of which is connected to the integrator 8. The output of the integrator 8 is at the same time the output of the system.
Elektromagnes 1 zasilany pradem i wytwarza pole magnetyczne, które wraz z polem wytwarzanym przez cewke 3 wzbudza w mierniku pola 2 napiecie U. Napiecie to podawane jest jednoczesnie na dwa woltomierze, a mianowicie na woltomierz napiecia przemiennego 5 i napiecia stalego 6, który mierzy napiecie U na mierniku pola 2 w funkcji pradu i plynacego przez elektromagnes 1. W cewce 3 wzbudza generator 4 pole zmienne AH2 97 888 O stalej i stabilizowanej amplitudzie. Z generatora 4 podaje sie napiecie o stalej czestotliwosci f do woltomierza , który otrzymujac równiez napiecie przemienne z miernika 2 podaje zaleznosc to Obie wielkosci z woltomierzy 5 i 6 podawane sa do przetwornika 7, który daje zaleznosc dU fU, -i di LH.The electromagnet 1 is energized and produces a magnetic field which, together with the field produced by the coil 3 induces the voltage U in the field 2 meter. This voltage is simultaneously applied to two voltmeters, namely on the AC voltmeter 5 and DC voltage 6, which measures the voltage U on the meter field 2 as a function of the current and flowing through the electromagnet 1. In coil 3, generator 4 is energized by alternating field AH2 97 888 With a constant and stabilized amplitude. From generator 4 a constant frequency voltage f is applied to a voltmeter which, also receiving the alternating voltage from the meter 2, gives the relationship is Both quantities from voltmeters 5 and 6 are fed to converter 7, which gives a relationship dU fU, -i di LH.
Funkcja ta, po scalkowaniu w integratorze 8 daje wartosc pola magnetycznego w zaleznosci od pradu i wedlug wzoru: H = /i dU[y_|-idi o di ltT o-This function, after merging in the integrator 8, gives the value of the magnetic field as a function of the current i according to the formula: H = / i dU [y_ | -idi o d ltT about-
