Product description
The tunnel-specific booster quickly solves the problem of low construction voltage in the tunnel. The special booster for tunnel construction is composed of voltage regulating transformer TS (including fuel tank, stator, rotor top cover, transmission control motor M, handwheel mechanism). The rotary voltage regulation is realized by the teletype motor or the hand wheel mechanism and the gear coupling. The rotation range is within 180°, and the electrical limit and the mechanical limit are arranged at the upper end of the fuel tank. The electrical limit is cut off by the travel switch, and the mechanical power is cut off. The limit is blocked by a protective bolt to limit its rotation. The stator winding and the rotor winding are fixed by the bottom seat and placed in the oil tank. The tank is equipped with 10# transformer oil. When the load generates heat, it is heated by the oil immersion cooling method.

Features
The tunnel-specific booster is mainly suitable for AC 50-60Hz. It is an ideal power supply for solving the problem that the power supply line is far away, the terminal voltage is too low, and the voltage fluctuation range is large, which makes the power equipment unable to start and operate normally. device. The product adopts the main body and the control system complement each other, with full-automatic pressure compensation, no contact adjustment, no instantaneous pressure loss, fast voltage regulation, wide voltage regulation range (three-phase input 220V-450V), strong overload capability, maintenance-free Features. It is convenient to use, safe and reliable; it greatly improves the continuous stability of power voltage regulation, and can be widely used in mining enterprises and tunnel construction units in remote mountainous areas (transport pumps, shotcrete machines, air compressors, blowers, ball mills, crushers. The hoisting machine, pump, and other high-current starting electromechanical click-to-document links have been well received by users such as mining companies and tunnel construction units since they were introduced to the market.
