Terdapat banyak piawaian untuk menilai kualiti elemen pemanas. Bagaimana kita boleh dengan mudah menguji kualiti elemen pemanas dalam kerja dan kehidupan seharian kita? Hari ini, saya akan berkongsi dengan anda cara menggunakan multimeter untuk menguji kualiti elemen pemanas.<\/p>\n\n\n\n
Aturkan multimeter pada julat 1K ohm, dan letakkan kedua-dua probe pada kedua-dua hujung wayar pemanas.<\/p>\n\n\n\n
Jika multimeter memaparkan nilai tertentu, ia bermakna wayar pemanas berfungsi dengan normal. Catatkan nilai rintangan. Jika tiada nilai dipaparkan, ia menunjukkan bahawa wayar pemanas terputus, dan elemen pemanas tidak boleh digunakan.<\/p>\n\n\n\n
Dengan menggunakan formula 220250\/nilai rintangan atau 380<\/em>380\/nilai rintangan, anda boleh mengira kuasa. Jika kuasa yang dikira menyimpang kurang daripada 5% daripada kuasa dinilai, elemen pemanas itu baik.<\/p>\n\n\n\n Jika penyimpangan kuasa besar, ia menunjukkan bahawa proses pembuatan tidak mengikut piawaian. Jika nilai kuasa terlalu tinggi, seperti melebihi 10,000, ia bermakna terdapat litar pintas pada wayar pemanas, yang boleh menyebabkan kebakaran atau kerosakan elektrik lain. Dalam kes ini, elemen pemanas tidak boleh digunakan.<\/p>\n\n\n\n GlobalQT mengkhusus dalam pembuatan berkualiti tinggi elemen pemanas kuarza<\/a>.
