Ndezvipi Zvishandiso zveHigh Voltage Fuse?

Chekutanga pane zvese, isu tinogona kutarisa maitiro eyakakwira voltage fuse.

Sezvatinoziva, basa rehigh voltage fusendiko kuchengetedza dunhu.Ndiko kuti, kana ikozvino munharaunda inodarika kukosha kwakatarwa, kunyunguduka mukati me fuse kuchabudisa rudzi rwekupisa kuputsa dunhu.Naizvozvo, kune yakakwira voltage fusing zvinhu, inoda kuve yakaderera kunyungudika, nyore kudzima arc maitiro.Kazhinji kusanganisira mhangura, sirivheri, zingi, lead, lead tin alloy uye zvimwe zvinhu.Nekuti kunyungudika kwezvinhu izvi kwakasiyana, zvinhu zvakasiyana zvinodiwa pamhepo dzakasiyana.Kunyungudika kwavo kunoenderana ne1080 ℃, 960 ℃, 420 ℃, 327 ℃ uye 200 ℃ zvichiteerana.

Mirayiridzo yekushandiswa kwezvinhu izvi zvakasiyana-siyana ndeyotevera:
1. Nzvimbo yakanyunguduka ye zinc, lead, lead-tin alloy nemamwe masimbi yakaderera, asi resistivity yakakura.Nokudaro, kushandiswa kwefuse cross-sectional area yakakura, iyo mhute yesimbi inogadzirwa kana fusing haibatsiri kudzima arc.Inonyanya kushandiswa mudunhu pazasi 1kV.
2. Mhangura nesirivheri zvine nzvimbo dzakanyanya kunyunguduka, asi diki resistivity uye yakanaka magetsi uye thermal conductivity.Nokudaro, kushandiswa kwefuse cross-sectional area iduku, mhute yesimbi inogadzirwa kana fusing iri shoma, nyore kudzima arc.Inogona kushandiswa mu high voltage, high current circuit.Zvisinei, kana ikozvino yakanyanyisa, tembiricha yenguva refu yakanyanyisa, zviri nyore kukonzera kukanganisa kune zvimwe zvikamu mu fuse.Kuti uite fuse yakanyunguduka nokukurumidza, inofanira kuyerera kuburikidza nehombe huru, kana zvisina kudaro ichawedzera nguva yefuse, iyo isingafadzi kumidziyo yekudzivirira.Kuti ubvise kukanganisa uku, tin kana lead pellet inowanzoiswa pamhangura kana sirivha yakanyungudika kuderedza kunyunguduka kwekushisa uye kuvandudza mashandiro ekudzivirira kwekunyungudika.
