Beschreibung
Zusammenfassung:	The invention provides a high voltage metering cabinet voltage loss alarm device which comprises a transformer assembly. The transformer assembly comprises a first transformer, a second transformer and a third transformer. The first input end of the first transformer and the first input end of the third transformer are connected with the A-phase output end of a voltage transformer assembly of a high voltage metering cabinet. The first input end of the first transformer and the first input end of the second transformer are connected with the B-phase output end of the voltage transformer assembly of the high voltage metering cabinet. The second input end of the second transformer and the second input end of the third transformer are connected with the C-phase output of the voltage transformer assembly of the high voltage metering cabinet. The high voltage metering cabinet voltage loss alarm device solves the problem that voltage loss of the voltage transformer in the high voltage metering cabinet cannot be dete
