Ndihwo huwandu hwakawanda hwemhepo iyo SPD ichatendera kuti ipfuure kune chishandiso chakachengetedzwa uyezve chiri chezasi chiri nani. Semuenzaniso, chishandiso chakachengetedzwa chinogona kumira zvakaringana 800V. Kana iyo SPD's VRP iri 1000V, chishandiso chakachengetedzwa chinokuvara kana kudzikisirwa.
Kukura Kwemazuva Ano
Iyo ndiyo yakanyanya huwandu hwekuwedzera kwazvino SPD inogona kusimuka pasi panguva yechiitiko chekuvhiya uye chiratidzo chehupenyu hwehupenyu hwePSD. Semuenzaniso, 200kA SPD ine hupenyu hwakareba kupfuura 100kA SPD pasi pemamiriro akafanana.
Nominal Discharge Current (In)
Ndicho chiyeuchidzo chepamusoro chekubuda kwemazuva iko kuburikidza neSSPD. SPD inofanira kuramba ichishanda mushure me15 In surges. Icho chiratidzo chekugadzirisa kweSDD uye ichi chiyero chekuti SPD inogadzira sei kana yakagadzirirwa uye inotarisana nezviratidzo zvinoswedera pedyo nehupenyu hwehupenyu hwechokwadi.
Maximum Discharge Current (Imax)
Ndicho chiyeuchidzo chepamusoro chekubuda kwemazuva iko kuburikidza neSSPD. SPD inoda kuramba ichishanda mushure me1 Imax surges. Kazhinji, ndeye 2-2.5 nguva yekukosha kweIn. Ichowo chiratidzo chekugwinya kweSDD. Asi iyo inokosha isiri iyo inokosha kupfuura In nokuti Imax inongedzo yakaipisisa uye mumamiriro ezvinhu chaiwo, kuwedzera kunowanzove kusina simba rakadaro. Nokuda kweiyo parameter, yakakwirira iri nani.
Muchidimbu Dunhu Rwakawanda (SCCR)
Icho chiyero chepamusoro chemazuva mashoma-circuit iyo chikamu kana kereke inogona kumira uye yakakwirira iri nani. MaSDD makuru makuru ePsurge akapfuura 200kA SCCR muedzo weE UL kunze kwekunze kunze kwekuparara kwemhepo uye fuse ndiyo inonyanya kushanda mumhizha.
Surge Protection Device Applications
Zvigadziro zvekudzivirirwa zvinoshandiswa zvakanyanya pamakambani akasiyana-siyana, kunyanya kune avo vanotambudza-mamishinari emishoni. Pasi pane urongwa hwekudzivirira kushanda uye zvigadziriswa zvinogadzirirwa neProsurge. Mumagetsi ose, tinoratidza SPD inoda uye nzvimbo dzayo yekuisa. Kana iwe uchida kune chero chekushanda, iwe unogona kutora uye kudzidza zvakawanda.

Pakupedzisira, tinosvika kumugumo wenyaya ino. Muchikamu chino, tinotaura nezvimwe zvinhu zvinonakidza sekudzivirira kwemheni, kubhururuka kwemhepo, kubhururuka uye kuvhara chipfeko. Ndinotarisira kuti iwe watoziva zvinonzwisisika zvekudzivirirwa kwechigadzirwa. Asi kana iwe uchida kudzidza zvakawanda nezvenyaya iyi, tine zvimwe zvinyorwa pane chikamu chedu chekudzivirira kudzivirirwa pane webhusaiti yedu.
Uye chikamu chekupedzisira chinokosha zvikuru chechinyorwa chino ndechokupa kuvonga kwekambani iyo inobereka mavhidhiyo mazhinji, mapikicha, zvinyorwa uye zvinyorwa zvose pamusoro pekudzivirirwa kwekudzivirira. Ivo ndivo vatungamiri mumakambani edu. Akafuridzirwa navo, tiri kupawo mugove wedu zvakare.
Kana iwe uchida nyaya ino, unogona kubatsira kugovana nayo!
