Embodiment Construction
[0023] Below in conjunction with accompanying drawing and embodiment the technical scheme of the present invention is described further,
[0024] The present invention provides a no-load transformer reactive power compensation device based on high power supply and high calculation, see figure 1 , The reactive power compensation device mainly includes: main switch QF, voltmeter V circuit, ammeter A circuit, main work compensation circuit, supplementary compensation circuit, three-phase electric energy meter circuit.
[0025] The V circuit of the voltmeter is connected to the A and N phases of the transformer through the fuse Fu and displays the voltage of the A phase at the low voltage side of the transformer.
[0026] The A circuit of the ammeter is connected in series on the secondary side of the current transformer Ta. The current transformer Ta is a feed-through type. The transformation ratio is determined according to the capacity of reactive power compensation. B-phase c...
