QZB series autotransformer for step-down start

以下的三相鼠笼型异步电动机作不频繁启动、停止之用骂我厂生产的QZB系列降压启动用自耦变压器外观整洁大方、体积小、重量轻、运行可靠,受到用户一致好评。 Auto-coupling step-down start is to reduce the power supply voltage by using an auto-transformer to reduce the starting power. At the same time, the starting power can be changed by selecting different taps of the auto-transformer to achieve the purpose of changing the starting transition. The impact on the power supply voltage is small, the impact on the machine is small during startup, and the motor startup time is short. It is usually used for three-phase squirrel cage asynchronous motors below 320kW for infrequent start and stop. The series auto-transformer for step-down startup has a neat appearance, small size, light weight and reliable operation, and has been well received by users.
