Rotating electrical machines - Part 4-1: Methods for determining electrically excited synchronous machine quantities from tests

IEC 60034-4-1:2018 applies to three-phase synchronous machines of 1 kVA rating and larger and describes methods intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is a limited applicability of the described tests, and special precautions should be taken against irreversible demagnetization.

Drehende elektrische Maschinen - Teil 4-1: Verfahren zur Ermittlung der Kenngrößen von Synchronmaschinen durch Messungen

Machines électriques tournantes - Partie 4-1: Méthodes pour la détermination, à partir d’essais, des grandeurs des machines synchrones à excitation électrique

L’IEC 60034-4-1:2018 est applicable aux machines synchrones triphasées dont la puissance assignée est supérieure ou égale à 1 kVA et décrit des méthodes destinées à être utilisées avec des machines ayant un enroulement d’excitation avec des bagues collectrices et des balais pour leur alimentation. Les machines synchrones sans balai d’excitation exigent un investissement particulier pour certains des essais. Pour les machines dont l’excitation est assurée par des aimants permanents, les essais décrits ont une applicabilité limitée et il convient de prendre des précautions particulières contre une démagnétisation irréversible.

Električni rotacijski stroji - 4-1. del: Metode za določanje parametrov sinhronskih strojev s preskusi (IEC 60034-4-1:2018)

Ta del standarda IEC 60034 se uporablja za trifazne sinhronske stroje z nazivno močjo 1 kVA in več.
Večina metod je namenjenih za uporabo s stroji, ki imajo vzbujalno navitje z drsnimi obroči in ščetkami za njihovo napajanje. Sinhronski stroji z vzbujanjem brez ščetk pri nekaterih preskusih zahtevajo posebno pozornost. Pri strojih s trajnim magnetnim vzbujanjem je uporaba opisanih preskusov omejena in upoštevati je treba posebne previdnostne ukrepe proti nepovratnemu razmagnetenju.
Izključeni so aksialni stroji in posebni sinhronski stroji, kot so induktorski stroji, stroji s prečnim pretokom in reluktančni stroji.
Ta dokument ni namenjen interpretaciji, da so kateri koli ali vsi v njem opisani preskusi nujni na katerem koli stroju. Posebni preskusi, ki jih je treba izvesti, so predmet dogovora med proizvajalcem in kupcem.
