S11 Non-Excited Voltage Regulator

Overview of S11 Non-Excited Voltage Regulator

S11 non-excitation voltage regulator meets national standards GB1094 "Power Transformer" and GB / T6451 "Three-phase oil-immersed power transformer technical parameters and requirements". On-load voltage regulation range: 10 ± 4 × 2.5% KV, 35 ± 3 × 2.5% KV, non-excitation voltage regulation range: 10 ± 2 × 2.5% KV, 35 ± 2 × 2.5% KV, which can be reached on the primary side The on-load, non-excitation voltage regulating switch adjusts the voltage manually, electrically or automatically within the voltage regulating range to ensure the stability of the output voltage. The body adopts three positions of upper, middle and lower positions and special anti-loose and anti-vibration measures, so that it is free from hanging core inspection before installation and has anti-vibration function. The fuel tank uses high-quality steel plates, high mechanical strength, and high-quality acrylic products are used for rubber strips and rubber pads. It does not age for long-term operation and effectively prevents the leakage of transformer oil.
