product description

This product is in the power grid in the use of silicon steel core magnetization curve of the saturation characteristics of the transformer connected into the opening of the secondary coil in the induction of zero sequence third harmonic potential of the principle of light-type test equipment.

The third harmonic frequency generator can be equipped with a set of products, including control equipment and chassis. The generator is a power system, power plant, substation, power distribution network for small-capacity power transformers: cascade high voltage Transformer frequency doubling induction high voltage test one of the basic equipment can also be a variety of low-voltage electronic, instrument power transformers, inductors coil electrical coil frequency doubling pressure test, but also as a power of not more than 1Kilowatt-doubled power supply for some special electrical equipment power supply or test.

This product is a static frequency conversion equipment, low noise, small size, in the high voltage system can replace the traditional frequency conversion unit

working principle

Three single-phase transformer side of the side of the star, the secondary side into the opening triangle, in the primary side with a symmetrical three-phase sine wave power supply, and increase the voltage so that the core magnetic circuit saturation, The composition of the third harmonic is increased ,Corresponding to the core coil induction third harmonic voltage is also increased.

This is output by the secondary side of the generator of the opening triangle 150Hertz (triple power frequency) induced voltage as the third harmonic test power supply voltage.

When the triplicate generator is brought (eg JCC -220Type high voltage cascade voltage transformer) load, the current from the emotional into the capacitive, due to the low power factor, the generator is less efficient, generally only 20%So that the reactor can be connected to an empty winding on the reactor for current compensation to improve the power factor of the entire test circuit.
