Three-Phase Oil-Immersed Voltage Stabilizer

The oil-immersed voltage stabilizer consists of a voltage regulator and a transformer, model SSTS (including oil tank, stator, rotor top cover, drive control motor M, handwheel, control circuit board and secondary circuit components for voltage regulation control).

It realizes rotary voltage regulation within a rotation range of 1800 degrees via motor drive or handwheel together with gear coupling. Besides, electric limit and mechanical limit devices are arranged on the top of the oil tank. For electric limit, the power supply of the motor is cut off by the limit switch; for mechanical limit, rotation is stopped by bolt protection devices. The stator winding and rotor winding are fixed by the base frame, and No.10 transformer oil is filled inside the oil tank. When heat is generated by the load, heat is dissipated through cooling tubes by oil immersion cooling.

The oil-immersed voltage stabilizer is equipped with phase failure, open-phase, overvoltage and overcurrent protection functions. Its main circuit features contactless voltage regulation, no mechanical wear, no spark, no interference and low failure rate. Moreover, this stabilizer boasts strong shock resistance, great instantaneous overload capacity, long service life and maintenance-free performance.

Product Advantages

- Stepless voltage regulation (brushless)
- By inductive and non-contact voltage regulation, the stabilizer can linearly increase or decrease the load voltage.
- Outstanding performance
- Adopting high magnetic flux density silicon steel sheets, this stabilizer minimizes no-load loss and no-load current, gives full play to its performance advantages and reduces electric energy consumption. It is robust, durable and long-lived.
- The internal structure of this voltage stabilizer is an Inductive Voltage Regulator (IVR) without carbon brushes, featuring wear resistance, sturdiness and long service life.
- Efficiency＞98%, no waveform distortion.

Application Fields

The oil-immersed voltage stabilizer is suitable for high-power industrial and mining enterprises such as mining, metallurgy, chemical industry and heavy machinery, as well as production scenarios with large load fluctuation including injection molding, machine tools, textile and printing. It can also meet the stable power supply demands of infrastructure projects such as construction sites, tunnels, airports and ports, plus large shopping malls, hospitals, schools and industrial parks. It is especially suitable for harsh environments with high temperature, high humidity, heavy dust and violent voltage fluctuation, and working conditions of long-term continuous operation.
