SPD xisirhelelo xa vuhlayiselo T2 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 a swi nge swi koti ku fambisana na SPD, loko mphakelo wa gezi wu nga tolovelekanga kumbe SPD ya onhaka naswona swi tsandzeka, ndzilo ni switirhisiwa swi onhiwa hi rihati, leswi khumbeke swinene matirhelo lama tolovelekeke 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:

 

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 application

 

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.

 

Swihlawulekisi swa swikumiwa

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.
