"Oil-cooled voltage regulators" usually refer to oil-immersed voltage regulators (also known as oil-cooled or oil-type voltage regulators). The core working principle combines electromagnetic voltage regulation technology with the cooling/insulation function of insulating oil.
It contains a silicon steel sheet core and oxygen-free copper windings to reduce losses.
On-load tap-changer or carbon brush sliding mechanism enables continuous stepless voltage regulation.
Filled with low-pour-point insulating oil (e.g., with a pour point of -50°C) to adapt to extreme environments.
It supports remote monitoring, fault early-warning, and harmonic filtering (THD can be reduced from 30% to <3%).
What are oil-cooled voltage regulators?
They usually refer to oil-immersed voltage regulators (also known as oil-cooled or oil-type voltage regulators). The core working principle combines electromagnetic voltage regulation technology with the cooling and insulation function of insulating oil.
What is the function of the voltage regulating transformer?
The voltage regulating transformer contains a silicon steel sheet core and oxygen-free copper windings designed to minimize energy losses during operation.
How is continuous stepless voltage regulation achieved?
Continuous stepless voltage regulation is achieved through an on-load tap-changer or a carbon brush sliding mechanism built into the system.
How do these regulators adapt to extreme cold environments?
They utilize a fully sealed oil tank filled with low-pour-point insulating oil (capable of reaching a pour point of -50°C) to ensure reliable operation in extreme temperatures.
How does the intelligent control system improve power quality?
The intelligent control system supports remote monitoring, fault early-warning, and harmonic filtering, which can significantly reduce the Total Harmonic Distortion (THD) from 30% to less than 3%.
