Mibvunzo Inowanzo bvunzwa: Zvinobvunzwa Nevanopa Mazano veMEP Vasati Vanyora Mutsetse weAir-Termination
Ko ESE arrester ingori kusimudzira kushambadzira kweFranklin rod here?
Kwete — asi chete kana mukana wayo wekuita kuti itange kushanda wava wechokwadi. ESE head ine chitupa inoburitsa streamer inokwira kumusoro makumi ema microseconds isati yasvika passive point, iyo inowedzera radius yakachengetedzwa pasi peNF C 17-102 formula. Yuniti isina report yerabhoritari yeΔT inoshanda se passive rod pasinei nechimiro chayo, saka report ndiyo tekinoroji.
Ndingaverenga sei Franklin rod protection radius?
Nekona yekudzivirira ye65°, radius iri padanho rakachengetedzwa hxyakaenzana ne2.14×(h−hx), uko h iri kukwirira kwemuromo wetsvimbo — iyo inotsanangurwa kuti tsvimbo dzedu dzemhangura dzakajairika dzakavakirwa pai. IEC 62305 nzira dzekutenderera nedzemeshi dzinopa mamwe majometri epfungwa imwecheteyo isingashande; taura nzira inoshandiswa nedhizaini yako mutsanangudzo.
Kusarudza ESE kunobvisa here kudiwa kwevanodzika pasi uye kuisira pasi?
Hazvina kumboitika. Musoro weESE unongovandudza kubatwa kwemhepo chete pamusoro; simba rekurova richiri kufamba richidzika pasi pemaconductors kuenda kumagumo enyika, ayo anofanira kusangana nezvinangwa zvakafanana neLPS chero ipi zvayo. Chero chirevo chekuti ESE system haina down-conductor chinofanira kubatwa sechiratidzo chinoratidza kuti hapana mhedzisiro.
Ndeipi tekinoroji yakachipa kune chivakwa chebhizinesi chemazuva ese?
Zvinoenderana nechimiro, kwete mutengo weyuniti. Masisitimu eFranklin anoshandisa mari pazviteshi zvakawanda, conductor mesh uye basa; masisitimu eESE anonyanya kushandisa mari mumusoro mumwe chete une certification, mast imwe yakagadzirwa uye magwaro ayo. Matenga makuru akati sandara anowanzo farira mast imwe chete yeESE; matenga madiki kana akaomarara anowanzo farira Franklin array. Enzanisa chimiro chose chakaiswa padhirowa chaiyo.
Ko purojekiti inogona kusanganisa magumo eESE neFranklin here?
Ehe, uye magadzirirwo emhando dzakasiyana-siyana akajairika apo nzvimbo dzakasiyana dzedenga dzine majometri akasiyana - chero bedzi zvirevo zvichiratidza mwero unotungamira wenzvimbo yega yega zvakajeka. Kusanganisa matekinoroji pasina kusanganisa mazwi kwakanaka; kusanganisa mazwi pasina kutaura kuti gakava riripo riri kumirira kuitika.
Musoro weESE unoda kugadziriswa kwakadini kana tichienzanisa netsvimbo isingashande?
Tsvimbo yeFranklin isingashande inoda kuongororwa nguva nenguva kwemajoini, kuenderera mberi kwayo uye kugadziriswa kwayo pamwe nekuyedzwa kwevhu. Musoro weESE unowedzera kuongororwa kwebasa remuchina unokonzeresa kuputika panguva imwe neimwe yemugadziri, sezvo mudziyo wakakundikana uchizopedzisira wava kushanda zvisina basa.
