<\/a><\/figure><\/div>\n\n\n\nUntuk peralatan yang aman secara intrinsik, pada suhu rendah, karakteristik kinerja komponen yang digunakan dalam peralatan yang aman secara intrinsik, seperti penghalang keselamatan, dan catu daya terbatas percikan api dengan komponen yang secara intrinsik dinamis akan berubah. Saat memilih komponen, perubahan ini harus diperhitungkan, dan evaluasi harus dilakukan sesuai dengan persyaratan \u201cPeralatan yang Dilindungi \u2018i\u2019 yang Aman Secara Intrinsik\u201d yang sesuai dengan menggunakan suhu pengoperasian yang ditentukan oleh produsen. Nilai pengenal ini harus memperhitungkan perubahan dalam pengoperasian komponen semikonduktor yang memengaruhi kinerja yang secara intrinsik aman untuk menyediakan fungsi yang secara intrinsik aman. <\/p>\n\n\n\n
Performa keamanan intrinsik catu daya dengan komponen dinamis yang aman secara intrinsik yang digunakan dalam sistem tersebut bergantung pada suhu sekitar lokasi aplikasi. Pada suhu rendah, sensitivitas komponen semikonduktor dinamis dari catu daya yang aman secara intrinsik berkurang dan waktu pengalihan meningkat. Peraturan yang sesuai menetapkan bahwa uji penyalaan percikan api harus dilakukan dalam pengaturan sirkuit yang paling rentan terhadap penyalaan. Namun, dalam praktiknya, pengujian biasanya dilakukan pada suhu laboratorium. <\/p>\n\n\n\n
Oleh karena itu, untuk sistem dengan catu daya perlindungan yang secara intrinsik aman yang bersifat dinamis di area yang melibatkan suhu rendah, kinerja yang secara intrinsik aman perlu diuji pada suhu dalam rentang aplikasi, termasuk suhu terendah komponen semikonduktor dinamis, dan dalam kondisi perangkat uji percikan dihubungkan ke beban yang sesuai pada suhu pengoperasian tertinggi. Komponen semikonduktor yang memberikan perlindungan yang secara intrinsik aman dalam suhu sekitar di bawah -40 \u2103 mungkin memerlukan sistem pemanas khusus. Untuk peralatan yang digunakan di iklim laut yang dingin, meskipun peralatan mematuhi jarak rambat yang sesuai dan Indeks Pelacakan Komparatif (CTI) bahan isolasi, tingkat perlindungan yang lebih tinggi dari IP54 mungkin diperlukan untuk memastikan bahwa endapan klorida pada permukaan papan sirkuit tercetak tidak menyebabkan pelacakan.<\/p>","protected":false},"excerpt":{"rendered":"
