Zusammenfassung: | The utility model discloses high-and-low-voltage whole-set wattles individual-compensation and common-compensation factory test equipment. Each phase of a three-phase input power supply of a testing station is connected with a test current output unit. The test current output unit comprises a transformer (1), a changeover switch (2), a rheostat (3), an ammeter (4), a power factor meter (5) and a phase shifting circuit (6). The phase shifting circuit (6) is serially connected with an auxiliary inductor (8), and the serially connected assembly is connected with a second tap (9) and a third tap (10) of a main inductor (7). The high-and-low-voltage whole-set wattles individual-compensation and common-compensation factory test equipment has advantages of simple structure and low fabrication cost. The high-and-low-voltage whole-set wattles individual-compensation and common-compensation factory test equipment can supply various analog experiment parameters and is suitable for high-and-low-voltage whole-set wattless compensation cabinet factory tests and various digital display indicators, comprehensive protectors, wattles compensation controllers, relay protection action simulation tests and various electric components for performing analog action tests. |
