Pangkalahatan ng Produkto:
Ang photovoltaic power generation inverter isolation transformer ay isang teknolohiya na direktang nagsasalin ng enerhiya ng liwanag sa elektrikong enerhiya gamit ang photogenerated volt effect sa semiconductor interface. Ang pangunahing elemento ng teknolohiyang ito ay ang solar cell. Maaaring mabuo ang mga solar cell na may pagbabalot at proteksyon sa serye upang mabuo ang malaking solar cell module. Kapag pinagsama ito sa power controller at iba pang komponente, nabubuo ang photovoltaic power generation device.
Karaniwang ginagamit ang photovoltaic transformers para sa solar inverters. Dahil sa mababang photoelectric efficiency ng photovoltaic transformer mismo, kaya nangangailangan ng mataas na efficiency ang transformer.
Ang grid-side wiring ng photovoltaic grid-connected inverter isolation transformer. Dyn11. YD5. Phase shift 120 degrees. Maaaring itakda ang PV isolation transformer upang gumana sa araw. Itigil sa gabi upang bawasan ang no-load loss ng enerhiya. Tumutugon ang three-phase photovoltaic transformer parameters para sa sanggunian.
