4. HRYDQ (W) Series of High-voltage Tester of Industrial Frequency Non-partial Discharge for Ultra-light-type Gas-filled-type Transformer
Introduction of A and B
As the only one of applying the SF6 gas-isolated technology, it replaces the oil-immersed transformer by the small volume, light weight, stabilization, and little-current of partial discharge. The voltage capacity of single transformer can even reach 1000kVA/1000kV. It’s also environment-friendly, free of maintenance, long using term, and excellent performances.

6. HRBSQ (SLQ/DDG) Series of Portable and Adjustable Current Amplifier
Introduction: It is a kind of contact ratio autotransformer which can adjust load voltage within rated voltage. This series of products are well designed because they adopt UK imported A brush for voltage adjusting parts. With strict quality control during production, this kind of device is very small, light, with low waveform distortion, low noise, and low temperature.
Capacity: 5、10、16、20、25、30、40、50、80、100、125、160……1500kVA
Maximum of phase of input and output:
Single phase: 220/0-250V,380V/0-430V
Three-phase: 380V/0-430(650)V
Notes: Direct output would be high voltage if not set.
Current amplifier which thermally stabilizes electrical devices is a kind of current source for testing use. For example, it can be used as low-voltage super-current source in motion stability test and temperature rising test of air circuit breaker, contactor, relay, and bus-bar. In addition, it can also be used as check current source of current transformer. Current amplifier, no matter if it’s the single phase or the three phase, the AC current or the DC current, is consisted of super-current generator (transformer), regulator and controller.
Working hour:
For rated voltage output, then working hour would be 2.5 minutes.
For 1/4 of rated voltage output, then working hour would be used in a long time.
