| titleOfInvention | Power supply type voltage transformer and electric energy metering device |
| abstract | A power supply type voltage transformer and an electric energy metering device, the power supply type voltage transformer comprising: the transformer comprises an iron core, a primary winding, a first secondary winding, a second secondary winding, a first straight-through current transformer, a second straight-through current transformer and an impedance; the grounding end of the primary winding is connected with a second straight-through current transformer in series; the grounding end of the first secondary winding is connected with a first straight-through current transformer in series; the second secondary winding loop is connected with an impedance in series, and the impedance is connected with the first straight-through current transformer in parallel; the primary winding, the first secondary winding and the second secondary winding are wound on the iron core; the secondary output current terminal of the second straight-through current transformer is used as a current sampling end and used for current metering; the second secondary winding terminal is used as a voltage sampling terminal for voltage measurement. The power supply type voltage transformer provided by the embodiment of the invention realizes the simultaneous measurement of current and voltage, and fills the technical blank of the power supply type voltage transformer in the electric energy measurement. |
