Gambaran Keseluruhan Transformer Voltan Rendah

20kva 380v to 220v Three Phase Low Voltage Dry Type Autotransformer is critical power equipment that uses the axiom of electromagnetic induction to convert AC voltage, termasuk voltan, semasa, penukaran impedans, pengasingan, dan fungsi kestabilan. Ia biasanya terdiri daripada tiga bahagian: gegelung primer, gegelung sekunder, dan teras besi (atau teras magnet). Transformer voltan rendah digunakan secara meluas dalam sistem kuasa untuk peraturan voltan, padanan impedans, dan pengasingan keselamatan. Ia juga biasa digunakan dalam pelbagai peranti dan litar elektronik, seperti peranti audio, penerima TV, bekalan kuasa komputer, dll., untuk mencapai fungsi seperti voltan, semasa, dan penukaran impedans. Selain itu, transformer voltan rendah juga memainkan peranan penting dalam keselamatan, mencegah kegagalan yang berlebihan baru-baru ini atau litar daripada menimbulkan ancaman kepada peralatan atau keselamatan diri dan melindungi peralatan daripada kesan berbahaya seperti perubahan kuasa secara tiba-tiba dan arus lonjakan.
