| Zusammenfassung: | The invention relates to a sequence indicator for indicating the phases of a three phase voltage source. According to the invention, the indicator comprises a magnetic system (1) with three columns having the shape of letter "E", some Y-connected coils (2a, 2b and 2c) being placed on said columns, while a yoke (3) is fastened at the free part of the extreme columns, the shaft of a cylindrical rotor (4) resting on two bearings for taper points in the middle of said yoke, an indicating pointer being rigidly mounted on said shaft of the cylindrical rotor, the motion of said indicating pointer above a graduated scale being protected by the case of a measuring apparatus.
Invenţia se referă la un indicator de succesiune a fazelor unei surse de tensiune trifazate. Indicatorul conform invenţiei este alcătuit dintr-un sistem (1) magnetic cu trei coloane, având forma literei "E", pe coloane fiind amplasate nişte bobine (2a, 2b şi 2c) legate în stea, iar la partea liberă a coloanelor extreme fiind fixat un jug (3) la mijlocul căruia se sprijină, pe două lagăre pentru vârfuri conice, axul unui rotor (4) cilindric, pe care este montat rigid un ac indicator, a cărui mişcare, deasupra unei scări gradate, este protejată de o carcasă (5) de aparat de măsură. |
