Menene Materials na High Voltage Fuses?

Da farko, za mu iya yin la'akari da halaye na high ƙarfin lantarki fuses.

Kamar yadda muka sani, aikin nababban ƙarfin lantarki fusesshine don kare kewaye.Wato lokacin da na'urar da ke cikin da'ira ta wuce ƙayyadaddun ƙima, narkewar da ke cikin fis ɗin zai haifar da wani nau'in zafi don karya kewaye.Saboda haka, don babban ƙarfin lantarki fusing kayan, bukatar samun low narkewa batu, sauki don kashe baka halaye.Gabaɗaya sun haɗa da jan karfe, azurfa, zinc, gubar, tin tin alloy da sauran kayan.Saboda abubuwan narkewa na waɗannan kayan sun bambanta, ana buƙatar kayan daban-daban don igiyoyi daban-daban.Su narkewa yanayin zafi dace 1080 ℃, 960 ℃, 420 ℃, 327 ℃ da 200 ℃ bi da bi.

Umarnin yin amfani da waɗannan abubuwa daban-daban sune kamar haka:
1. The narkewa batu na zinc, gubar, gubar-tin gami da sauran karafa ne in mun gwada da low, amma resistivity ya fi girma.Don haka, yin amfani da fuse cross-section area ya fi girma, tururin ƙarfe da ke haifarwa lokacin da fusing ba shi da amfani don kashe baka.Yafi amfani a cikin kewaye kasa 1kV.
2. Copper da azurfa suna da manyan abubuwan narkewa, amma ƙananan juriya da ingantaccen ƙarfin lantarki da thermal.Saboda haka, yin amfani da fuse cross-section area yana da ƙananan, tururin ƙarfe da aka haifar lokacin da fusing ya ragu, mai sauƙi don kashe baka.Za a iya amfani da shi a cikin babban ƙarfin lantarki, high halin yanzu kewaye.Duk da haka, idan halin yanzu yana da girma sosai, zafin jiki na dogon lokaci yana da yawa, mai sauƙi don haifar da lalacewa ga sauran abubuwan da ke cikin fis.Don yin narke fuse da sauri, dole ne ya gudana ta cikin babban halin yanzu, in ba haka ba zai tsawaita lokacin fuse, wanda ba shi da kyau ga kayan kariya.Don kawar da wannan gazawar, ana yawan walda kwano ko pellet ɗin dalma akan narkakken tagulla ko azurfa don rage zafin narkewa da haɓaka aikin kariya na narkewar.
