<\/a><\/figure><\/div>\n\n\n\nUntuk peralatan selamat intrinsik, pada suhu rendah, ciri prestasi komponen yang digunakan dalam peralatan selamat intrinsik, seperti halangan keselamatan, dan bekalan kuasa terhad percikan dengan komponen selamat intrinsik dinamik akan berubah. Apabila memilih komponen, perubahan ini perlu diambil kira, dan penilaian hendaklah dijalankan mengikut keperluan \u201cPeralatan Dilindungi \u2018i\u2019 Selamat Secara Intrinsik\u201d yang berkaitan menggunakan suhu operasi yang ditetapkan oleh pengeluar. Nilai penarafan ini hendaklah mengambil kira perubahan dalam operasi komponen semikonduktor yang menjejaskan prestasi selamat secara intrinsik bagi menyediakan fungsi selamat secara intrinsik yang diperlukan. <\/p>\n\n\n\n
Prestasi keselamatan intrinsik bekalan kuasa dengan komponen dinamik yang selamat secara intrinsik yang digunakan dalam sistem sedemikian bergantung pada suhu persekitaran tapak aplikasi. Pada suhu rendah, kepekaan komponen semikonduktor dinamik bekalan kuasa yang selamat secara intrinsik berkurang dan masa peralihan meningkat. Peraturan yang berkaitan menetapkan bahawa ujian percikan perlu dijalankan dalam susunan litar yang paling berpotensi untuk penyalaan. Walau bagaimanapun, dalam amalan, ujian biasanya dijalankan pada suhu makmal. <\/p>\n\n\n\n
Oleh itu, bagi sistem yang menggunakan bekalan kuasa perlindungan selamat intrinsik bersifat dinamik di kawasan yang melibatkan suhu rendah, prestasi selamat intrinsik perlu diuji pada suhu dalam julat aplikasi, termasuk suhu terendah komponen semikonduktor dinamik, dan di bawah keadaan di mana peranti ujian percikan disambungkan kepada beban yang sesuai pada suhu operasi tertinggi. Komponen semikonduktor yang menyediakan perlindungan selamat intrinsik dalam suhu persekitaran di bawah -40 \u2103 mungkin memerlukan sistem pemanasan khas. Bagi peralatan yang digunakan dalam iklim marin sejuk, walaupun peralatan tersebut mematuhi jarak perayapan dan Indeks Penjejakan Perbandingan (CTI) bahan penebat yang sepadan, tahap perlindungan melebihi IP54 mungkin diperlukan untuk memastikan bahawa endapan klorida pada permukaan papan litar bercetak tidak menyebabkan penjejakan.<\/p>","protected":false},"excerpt":{"rendered":"
