SFQ Series Triple Frequency Induction Voltage GeneratorDetailed product description：

Main purpose:

The SFQ series triple frequency induction voltage generator is designed according to the national standard GB311.1-97 to meet the requirements of high-voltage transformers and transformer double frequency induction withstand voltage testing equipment in power systems. It is widely used for AC induction withstand voltage testing of 35-220kV voltage level cascade voltage transformers in power systems to assess the main and longitudinal insulation strength of the transformers. It can also be used for induction withstand voltage testing of motor and small transformer windings, and can also be used as a 150Hz triple frequency power supply for short-term operation.

Key Features:
The SFQ series triple frequency induction voltage generator adopts a three core five column structure, and the working magnetic flux density of the iron core is selected above the saturation magnetic flux density, so that the vector sum of the fundamental potential (positive sequence vector) in the secondary winding formed by the opening into a triangle is 0, and the 150Hz third harmonic (zero sequence) of the same phase should be generated at both ends of the opening.
