TNSJA-3000KVA 3Phase, Industrial-Grade, Oil-Immersed Induction-type Brushless AVR

Product Features:

TNSJA seriesOil-immersed Induction(Brushless/Stepless) Voltage Stabilizer is composed of voltage regulator and transformer SSTS (including, oil tank, stator, rotor top Cover, drive control motor M, hand wheel, control circuit board and secondary circuit elements for voltage regulation control. It achieves the rotational voltage regulation through electric motor drive or hand wheel and gear coupling within the rotation range of 180. Besides, it is provided with the electric SS limit and mechanical limit on the upper end of the oil tank. For electric SS limit, the power supply of motor is switched off by a limit switch and for the mechanical limit, the rotational limit is stopped by bolt protector. The stator winding and rotor winding are fixed by the base frame and put into the oil tank with 10 # transformer oil. When the load generates heat, the heat dissipates from the radiating pipe by the way of Oil-immersed cooling. The oil immersed voltage stabilizer has the functions of phase failure, phase loss, overvoltage and over-current protections, and its main circuit has the characteristics of contactless voltage regulation, no mechanical wearing, no spark, no interference and low failure rate. In addition, this voltage stabilizer has the advantages of high impact resistance, super strong instantaneous overload capacity, long service life and maintenance free, it has the following features: 1). Stepless voltage adjustment (brushless): With inductive and contactless voltage regulation, the voltage stabilizer can increase and decrease the load voltage linearly. 2). Excellent features: By using high-magnetic-inductivity silicon steel sheet made in Japan, this voltage stabilizer minimizes the no-load loss and no-load current, and with its performance utilized best, reduces power loss.  3). Robust, durable and long life expectancy: The internal body of this voltage stabilizer is induction voltage regulator IVR, containing no carbon brush and its main characteristics are permanent wear-proof, robust and long service life. 4). High efficiency, and low power consumption:Efficiency: >98%, Power consumption≤1%
