Kana iyo yakakwirira-kukosha ruzivo magetsi zvigadzirwa zvemagetsi muchivako, kugona kwavo kutsungirira kubhururuka kwemheni kuri kudiki pane iyo yemidziyo yemagetsi ekutanga, zvinodikanwa kushandisasurge protectorkuchengetedza yakakwira-chaiyo zvigadzirwa zvemagetsi, zvino maitiro ekusarudza kuvhiya Zvakadini nevadziviriri?
Usati wasarudza asurge protector, iva nechokwadi chekuita mheni inorova njodzi yekuongorora uye kufunga nezvehupfumi hwepurojekiti, kwete chete kurasikirwa kwakananga, asiwo kukuvadza kusina kunanga (kune ruzivo rwekugadzirisa ruzivo, kukanganisa kusina kunanga kunowanzo kukwirira kudarika Mukuwedzera, mitemo yakakodzera nemitemo. nhasi zvinoda kuiswa kwesurge vadziviriri, zvakadai semabhizimusi emunyika mitemo yakadai seGB 50057. Pazasi, ini ndichatsanangura nzira yekusarudza muchengeti wekuvhiya kubva kumatanho akawanda.

Kuti uve nechokwadi chekuti masystem akaomarara ekupa magetsi uye masisitimu eruzivo haazokuvadzwa nekurova kwakananga mheni uye kuvhiya, IEC 62305 inotsanangura zvakajeka tsananguro yenzvimbo dzekudzivirira mheni.

LPZ 0A: Kuratidzwa kune yakananga kurova kwemheni, inotakura ese mheni mafungu uye ese mheni magetsi emagetsi minda.

LPZ 0B: Dziviriro kubva kune yakananga kurova kwemheni, inomira isina chidimbu mheni ikozvino kana kukonzeresa ikozvino, uye yakazara mheni yemagineti.

LPZ 1: Dziviriro kubva kune yakananga kurova kwemheni, mafungu emheni emunharaunda kana mafungu akacheneswa, uye attenuated mheni magineti.Kuvhiya uku kunogumira pakuvharirwa pamuganho uye kuchengetedzwa nemudziviriri wekuvhiya, uye munda wemagetsi wakadzivirira kuvharirwa.

LPZ 2…n: Yakafanana neLPZ 1, asi nekumwe kudzoreredzwa kwenzvimbo yemagetsi yekurova kwemheni.Semutemo wedziviriro, chinhu chakadzivirirwa chinofanirwa kuiswa munzvimbo yeLPZ ine magetsi emagetsi anoenderana nekugona kumirisana nekukuvadzwa kudzikisa kukuvadzwa (kukuvara kwemuviri, kutadza kwemagetsi nemagetsi masisitimu nekuda kwekuwandisa, nezvimwe.

Kana zvisingabviri kuyera kirasi 1 surge protector (Type1, Class1), Iimp≥12.5kA inowanzoshandiswa, kureva kuti, 12.5kA inokwana mumamiriro ezvinhu akawanda.Tinokurudzira kushandisa Iimp = 25kA, kuitira kuti pave neKukura kwehuwandu, iyo yakareba hupenyu hwebasa.

Kune vadziviriri vekuvhiya vekirasi 2 (Type2, Kirasi2), tinosarudza kuisa 20/40kA (In=20kA, Imax=40kA) magetsi ekudzivirira ekudzivirira, uye kurova kwemheni pamusoro pe40kA (mushure meLPZ1) hazviwanzo kugadzirwa mumashandisirwo chaiwo.ye.Kune akawanda marudzi eKirasi 2 ekuvhiya anodzivirira, anosanganisira 40/80kA, 50/100kA, uye 60/120kA magetsi ekuvhiya anodzivirira.

Sangana nezvinodiwa zvekuchengetedza mumatunhu matatu anoshanda

1. Mamiriro ekumirira: voltage kuchembera maitiro, humidity uye kupisa kwekudzivirira maitiro, yakachengeteka kutakura ikozvino yehuviri-chiteshi chekudzivirira chekudzivirira;

2. Surge kudzvinyirira mamiriro: Pamusoro pesimba reiyo system inoshanda voltage, iyo surge protector inewo simba kubva kusurge voltage;

3. TOV inoshanda mamiriro: Kushushikana kwemagetsi kwesurge protectoriri kunyanya TOV inoshanda voltage uye yazvino.Izvi zvine chekuita nemhando yegridi, yakaderera magetsi magetsi uye masisitimu ekugovera, masisitimu epakati magetsi ekuparadzira uye nzira dzekudzika dzekugovera matransformer.Chinodiwa izvi kugona kwemudziviriri wekuvhiya kumirisana nekupfuura overvoltages, kureva kuti, mudziviriri wekuvhiya anogona kumira neUT yakatsanangurwa muyero.

Authoritative certification kumba nekune dzimwe nyika

Mukupedzisira, zvakakoshawo kusarudza zvigadzirwa zvine mvumo yechitatu-bato certification (senge CE, TUV, CAS, CQC, nezvimwewo), uye kusarudza makambani ane tekinoroji kuunganidza, hunyanzvi hwakanakira, uye mhinduro dzinonzwika.

Sekureva kweTUV, CE, CQC uye zvimwe zvitupa zvepasirese, mudziviriri wekuvhiya ane tekinoroji yekugadzira yakanakisa uye tekinoroji yekugadzira mumunda wekudzivirira mheni, uye inogona kusangana nezvinodiwa zvekushandisa pasi pemamiriro ezvinhu akanyanya sekupisa, tembiricha yepamusoro uye nzvimbo dzemapani, uye inogona kumira harmonic ikozvino uye overvoltage kwenguva yakareba.,Surge protectorsinogona kugadzirirwa vatengi munzvimbo dzakasiyana.
