Oil Immersed Reactor
An Oil Immersed Reactor is a critical device in power transmission and distribution networks, designed to control reactive power, stabilize voltage, and improve power quality. The Oil Immersed Reactor is widely used in high-voltage and extra-high-voltage applications, where reliability, cooling efficiency, and long-term durability are essential.
Working Principle of Oil Immersed Reactor
The Oil Immersed Reactor consists of a reactor winding immersed in insulating oil. The oil serves multiple purposes: it provides electrical insulation, dissipates heat generated during operation, and protects the reactor from environmental influences. By connecting the Oil Immersed Reactor in series or parallel with transmission lines or busbars, it can absorb or limit reactive power, reducing overvoltages and enhancing voltage stability.
The Oil Immersed Reactor operates continuously under varying load conditions. Its design ensures low loss, high thermal stability, and effective control of inductive currents. Compared with dry-type reactors, the Oil Immersed Reactor is better suited for heavy-duty and high-voltage applications due to its superior cooling and insulation properties.
