Variable frequency resonance test set

 XHBP Variable Frequency Resonance Test Set   Descriptions:   It is specially designed and manufactured for AC voltage withstand test in primary electrical equipment of transformer substation, which meets the requirements of capacitive AC voltage withstand test. Compared with same products in China, there are many key advantages as follows:   It is consists of four parts-variable frequency power supply, excitation transformer, reactor and capacitive voltage potentiometer. The rectified silicon stack is connected behind capacitive voltage divider to complete the DC withstand voltage test.   1.Reactor with same voltage class and capacity is relatively small in size and light weight; 2.Temperature increases during rated load; 3.Featured as high electrical strength, good electrical insulation performance ; 4.Featured as elegant outline and rugged performance 5.Featured as many operating modes, easy to use, convenient to pick power on site Specifications:   1.Rated output voltage: 500 KV and <500 KV( AC effective value) 2.Output frequency: 20 to 300 Hz 3.Resonance voltage waveform: pure sine wave, waveform deviation factor <1.0%. 4.Max test capacity: 1,000kVA and <1,000kVA 5.Operating time: 60 min continuous operating time in case of full power 6.Quality factor: 30 to 90 7.Frequency regulation: sensitivity: 0.1Hz, degree of instability<0.05%  8.Operating power supply: 380/220V±15%/50Hz±5%               5.Diagrams 5.1 Test principle diagram
