◆ Products I produced the the QSG high-pressure series starter autotransformer (system voltage 6kV to 10kV) use to reduce the supply voltage to reduce the starting current, at the same time can be changed by selecting different tap autotransformer starting current and achieve the purpose of changing the starting torque, and this starting mode when starting the power supply voltage is small, the impact on the device is also smaller. The ratio of the starting current and starting torque the buck starting process, reduce the turns ratio squared times. In the same starting torque, auto-transformer voltage starting current is obtained from the power grid, the starter is much smaller than the resistance buck small grid current impact, loss of power. Starter autotransformer also called starting compensator. In other words, if the starting current of the same size, to obtain from the grid autotransformer reduced voltage starting will produce a larger starting torque. The startup process is very short (typically a few seconds to two minutes). Normal should be used in strict accordance with the start-up time use, can be two consecutive start, two starts must be spaced 6 to 8 hours before the next start, never allow multiple uninterruptible start. As soon as possible after startup must reactor resection, otherwise it will affect their life. ◆ perform standard GB1094.11 "dry-type transformers GB1094.1 power transformer" IEC60076 "power transformer" GB/T10228 "dry-type power transformers technical parameters and requirements" ◆ matching motor power: 110kW 25000kW ◆ Insulation class: Class F or H ◆ conditions of use a no more than 1000m above sea level altitude. b Ambient temperature -25 ~ +45 ℃ c. approximately sinusoidal waveform of the supply voltage of the power supply voltage waveform. d. multiphase power supply voltage symmetry multiphase transformer connected to the power supply voltage should be approximately symmetrical.
