SPD xisirhelelo xa vuhlayiselo T1 series
Nkatsakanyo wa swikumiwa
Hi ku ya hi swipimelo swa GB18802.1, GB50057 na Q/THQBOO1-2013, makumu ya le mahlweni ya SPD loop ya fanele ku hlanganisiwa hi ku landzelelana na switirhisiwa swa nsirhelelo wa overcurrent leswi lavekaka hi muendli wa surge protector.
Hikuva fuse ya sweswi na miniature circuit breaker aswi koti ku fambisana na SPD, loko mphakelo wa gezi wunga tolovelekanga kumbe SPD yi onhaka naswona yi tsandzeka, ndzilo na switirhisiwa swi onhiwa hi rihati, leswi khumbeke swinene matirhelo ya ntolovelo ya vuhumelerisi!
Sweswi, nhlayo leyikulu ya swisirhelelo swa xirhendzevutana leswitsongo leswi tirhisiwaka swin’we na SPD a yi nge ringanisiwi eka tinhla ta mune leti landzelaka:
1.The rihati current shock swa olova swinene ku onha-the rihati nsirhelelo wa tsandzeka;
2.High masalela voltage ya rihati impulse current-ku tshembheka ka rihati nsirhelelo wa switirhisiwa ku hungutiwile;
3.The matimba frequency free-wheeling a yi trip-mphakelo wa gezi a wu tolovelekanga naswona SPD yi pfurha ndzilo;
4.Ku khumbeka ka rihati ku khunguvanyeka hi xihoxo-nsirhelelo wa rihati wa tsandzeka.
Hi ku languta xiyimo xa sweswi xa leswaku a ku na xitirhisiwa xo seketela xa SPD lexi kongomeke xa nsirhelelo wa overcurrent eka indasitiri ya nsirhelelo wa rihati, endzhaku ka malembe manharhu ya ndzavisiso na nhluvukiso na ku tlula lembe rin’we ra swikambelo swo hambana swa ku tekelela mbango elaboratori, swi tiyisisiwile leswaku SPD backup protector (SCB) .
1.SPD matimba frequency freewheeling riendzo nkoka 4A
2.Non-trip impulse current yi tlula 40kA (8/20);
3.Lightning nsusumeto masalela ntshikilelo. Ku tlhantlha hi ku helela xiyimo xa sweswi xa leswaku SPD a yi na switirhisiwa swo hlawuleka swa nsirhelelo wa ku tlula mpimo; Vuyelo byo kongoma bya ntirhisano exikarhi ka SCB na SPD i ku tiyisisa leswaku SPD a yi khomi ndzilo naswona ku khumbeka ka current ya rihati a ku khunguvanyeki.
Ntirho na vukulu bya ku tirhisiwa
SPD special external disconnector yi hlanganisiwile hi nxaxamelo eka SPD loop, naswona xitirhisiwa xa le ndzeni xa xiteji xo hlawula sweswi xi tirhisiwa ku lemuka matimba frequency small current quick break; High current lightning impact ayi khunguvanyeki. Fikelela ntirho wa matimba frequency small current SPD nsirhelelo wa ndzilo na rihati ku khumbeka SPD nsirhelelo lowu yaka emahlweni; Switirhisiwa swa SCB swi tirhisiwa ntsena eka nsirhelelo wa SPD loop overcurrent, kumbe nsirhelelo wa backup current. Hi kombela leswaku u nga ti tirhisi eka swiendlakalo swin’wana.
Xivumbeko xa xiendliwas
1. Parameter-controlled tripping mechanism, leyi nga lemukaka ku hlawula ku tshoveka hi current;
2. Voltage leyi saleke ya impulse current yi le hansi, leyi nga ringanisiwaka na ya fuse;
3. Ku hlangana ka eneji ya le henhla, na vutomi byo leha bya vutirheli;
4. Xivumbeko lexi tshovekeke xa micro, vholumo leyitsongo, swi olova ku tsandzeka ka gezi ku kuma SPD;
5.Ku hetiseka swihlawulekisi, ku fikelela swilaveko swa ku seketela SPD eka swiyimo swa T1, T2 na T3.
Ku vekiwa ka 6.35mm clamp rail swi fikelela swilaveko swa ku vekiwa emisaveni hinkwayo.
