Oil-immersed regulator Oil-immersed self-cooling induction regulator
Application: The induction voltage regulator can adjust the output voltage steplessly, smoothly and continuously under load conditions. Mainly used for electrical and electrical testing, electric furnace temperature control, rectifier equipment matching, generator excitation, etc. Oil-immersed voltage regulators are widely used in machinery manufacturing, chemical, textile, communications, military and other industries.
Oil immersed regulator features:
1 Non-contact adjustment, long service life;
2 Suitable for loads of various natures;
3 Strong overload capacity;
Oil-immersed voltage regulator Reliable operation, easy to use and maintain. Induction voltage regulator The working principle and structure are similar to the locked-rotor asynchronous motor, and the energy conversion relationship is similar to that of an autotransformer. With the help of transmission mechanisms such as handwheels or servo motors, angular displacement is generated between the stator and the rotor, thereby changing the phase and amplitude relationship between the stator winding and the rotor winding induced electromotive force, so as to achieve the purpose of adjusting the output voltage. There are two types of induction voltage regulators: three-phase and single-phase.
Oil-immersed voltage regulator If the rotor position is changed, that is, the angle α is changed, the secondary output voltage U2 can be smoothly adjusted. The maximum and minimum output voltage are respectively. The structure and voltage regulation of the single-phase induction voltage regulator are similar to the three-phase induction voltage regulator, but its stator and rotor are both single-phase windings. Since the inductive regulator has no sliding contacts, it operates reliably. However, it only rotates an angle during the pressure regulation process, and does not rotate continuously, so the heat dissipation condition is poor. Air cooling can be used for those with small capacity, and oil cooling is required for those with large capacity. The weight, excitation current and loss of the induction voltage regulator are all larger than that of the autotransformer. Voltage regulator product use
It is suitable for surge tanks (stations) in urban residential areas, and also for industrial users such as boilers, industrial furnaces and kilns that have different requirements for urban gas pressure.
