Detailed Description: DBW / SBW series of high-power automatic compensation regulator DBW / SBW Series is in reference to the international similar products, combined with China's national conditions on the basis of the development and production of a new generation of energy-efficient power regulator with capacity Large, high efficiency, voltage range, high precision, strong protection, no waveform distortion, small size, light weight, reliable operation, easy maintenance and so on. Structure: It consists of a three-phase compensation transformer, three-phase regulating transformer, transmission, brush contact system, cabinet and control systems and other components. Three-phase regulating transformer winding cylindrical outer surface by burnishing, removing the insulation, the conductor surface was smooth, so good contact in the brush; a motor drive mechanism and sprockets, chains composition; reasonable structure brush system reliable, in order to ensure brush pressure; box with closed cabinet, small size, good heat dissipation, instrumentation striking position, indicating accurate. Working principle: SBW series regulator TB three-phase compensation transformer, three-phase regulating transformer TUV voltage detection unit, motor control and transmission, electronically controlled operation of the circuit, the protection circuit. TUV regulating the output of the transformer primary winding connected to a Y-connector in the regulator, TB compensation transformer secondary winding is connected primary winding of the transformer and the compensation works, excluding compensation transformer impedance drop, Uao = Uai Uac formula in: Uai- A phase input voltage regulator; Uao- A phase output voltage regulator; Uac- A phase compensation voltage regulator; its principle is: When the A-phase output voltage Uai increase △ Uai, offset voltage Uac also changed △ Uac and △ Uac = - when △ Uai, the A-phase output voltage Uao unchanged, empathy B phase, C phase as well. Its regulation process is: based on the output voltage changes, the voltage detection unit sampling, detection and output signal to control rotation of the motor SM, the reduction mechanism and a chain driven slide brush assembly on regulating transformers TUV (or scroll) to adjust The second voltage regulator to change the compensation voltage polarity and magnitude, to achieve output voltage regulation accuracy of automatic stabilizers in the permitted range, so as to achieve the purpose of automatic voltage regulator. Technical Parameters: Input voltage: single-phase 220V ± 20% or 220V ± 30% three-phase four-wire phase voltage 220V ± 20% line voltage 380V ± 20% or phase voltage 220V ± 30% line voltage is 380 ± 30% (when ordering need to explain) Output voltage: single-phase 220V; phase voltage three-phase 220V; 380V line voltage output accuracy: 2-5% (adjustable) Frequency: 50Hz / 60Hz Efficiency: ≥98% (power level above 50KVA) Ambient temperature: - 10 ℃ ~ 40 ℃ Insulation resistance: ≥2MΩ electrical strength: positive frequency sinusoidal voltage 2000V for 1 minute without breakdown and flashover overload: twice the rated current, 1 min waveform distortion: no additional waveform distortion Protection: over-voltage, over current, phase loss, phase sequence protection (single-phase phase and phase sequence protection) and mechanical failure protection response time: ≥1.5S (when the external voltage change 10%) Conditions: SBW series regulator should be indoor use, the normal conditions: 1) Ambient temperature: -10 ~ 45 ℃; 2), Altitude: not more than 1000 m; 3), relative humidity: ≤90%; 4), the installation site should not have an impact gas, steam, chemical deposition, dust, dirt and other explosive regulator insulation and aggressive substances; 5), the installation site without serious vibration or bumps.
