Products overview
The HMCXZ 2080kVA/520kV frequency-modulated series resonance test set is primarily designed and manufactured for AC withstand voltage testing of 10kV, 35kV, 110kV, and 220kV cables, as well as power transformers and all major electrical equipment in power systems. The reactors are designed as multiple separate units to meet the testing requirements for equipment operating at high voltage and low current.

FAQs
Q: If four reactors are connected in parallel, what are the inductance, maximum output current, and maximum output voltage, respectively?
A: Inductance: 30 H, maximum output current: 16 A, maximum output voltage: 130 kV
Q: What is the maximum continuous operating time of the unit?
A: Continuous operation is permitted for 180 minutes (3 hours) under rated load, with a temperature rise of ≤65 K.
Q: What is the quality factor of the reactors?
A:Q ≥ 30 (f = 45 Hz), while the quality factor of a single high-voltage reactor is Q ≥ 50 (f = 45 Hz), which exceeds the overall requirement for the unit.
