Pendahuluan<\/strong><\/h2>\n
\n

Lampauan voltan dan undervoltage tiga fasa empat wayar <\/a>pelindung JGGQ-80S\/3P+N Ia adalah peningkatan daripada jenis produk biasa, ciri teknikal produk: penggunaan kuasa rendah, jangka hayat panjang, kawalan tepat, perlindungan kekurangan fasa, perlindungan kekurangan talian sifar, had arus litar pintas maksimum 3000A, kawalan perisian mesra pengguna, dan petunjuk jelas dengan lampu LED, produk ini dihidupkan buat pertama kali dalam keadaan bekalan kuasa biasa dengan masa penutupan 5 saat, apabila berlaku ketegangan rendah pada talian, kehilangan fasa dan kecacatan lain, apabila bekalan kuasa kembali normal, masa penutupan adalah 20 saat, reka bentuk ini menjimatkan terlalu banyak masa menunggu apabila grid kuasa terhenti.<\/span><\/p>\n

Pelindung lebih\/kurang voltan tiga fasa empat wayar yang boleh diatur semula secara automatik mempunyai fungsi kehilangan fasa, kehilangan sifar, ketegangan berlebihan<\/a> dan perlindungan voltan rendah, dan sering digunakan dalam talian pengagihan tiga fasa empat wayar dan kotak penyambung penjanaan kuasa fotovoltaik.<\/p>\n
