Brief Introduction about Tunnel high-power three-phase oil immersed voltage regulator below:
The working principle of the 800kva oil immersed voltage regulator is mainly based on the principle of oil immersed transformers or reactors. By adjusting the magnetic field strength of the transformer core, the output voltage is maintained within a constant range. When the voltage in the power grid fluctuates due to factors such as load changes, line length, and power output fluctuations, oil immersed regulators can automatically sense this change and maintain the output voltage at the set value by adjusting their self inductance and mutual inductance. This automatic adjustment capability enables oil immersed voltage regulators to ensure stable output voltage even in the presence of large voltage fluctuations inside the mine, thereby ensuring the normal operation of equipment inside the mine.
The oil immersed contactless voltage regulator adopts oil immersed and contactless technology, which has higher stability and reliability, and is suitable for the power needs of various industrial scenarios.
