SPD okugaruzaho omurinzi T1 omubaro
Okureeba ebintu omu bwijwire
Okurugirira aha mutindo gwa GB18802.1, GB50057 na Q/THQBOO1-2013, omuheru gw‘omumaisho gwa SPD loop guteekwa kukwatiraine omu nkora n‘ebikwato by‘okwerinda ebirikukiraho ebirikwetengyesa omukozi w‘okwerinda kw‘okusheeshasheesha.
Ahabw’okugira ngu fiyuzi eriho hati na miniature circuit breaker tibirikubaasa kukwatanisa na SPD, amashanyarazi gaaba gatari ga buriijo nari SPD yaaba neesiisikara kandi ekaremwa, omuriro n’ebikwato nibishiisha ahabw’enkuba, ekiine akakwate kakuru n’okukora kwa buriijo okw’okukora ebintu!
Obwahati, omubaro muhango gw‘ebikwato by‘okuhenda amashanyarazi ebikye ebirikukoresibwa hamwe na SPD tibirikubaasa kugyeragyeranisibwa omu nshonga ina ezi:
1.Okushoberwa kw’amaani g’enkuba nikworeka ngu kyorobi munonga kushiisha-okwerinda kw’enkuba nikuremwa;
2.High residual voltage y'okurabura impulse current-okwesigwa kw'okurinda enkuba kw'ebikwato nikukyendeera;
3.Amashanyarazi frequency free-wheeling tigarikuteera-amashanyarazi tigari ga buriijo kandi SPD eri aha muriro;
4.Enkuba neeteera orugyendo ahabw’enshobi-okwerinda kw’enkuba nikuremwa.
Okureeba embeera eriho hati ngu tihaine kikwato ky‘okwerinda ekirikuhagira SPD-specific omu by‘okwerinda kw‘enkuba, bwanyima y‘emyaka eshatu y‘okucondooza n‘okutunguuka n‘okugyezesa okurikurenga aha mwaka gumwe kw‘okugyeragyeranisa eby‘obuhangwa okutarikushushana omu laboratory, nikihamibwa ngu SPD backup protector (SCB) .
1.SPD amaani emirundi mingi omuhendo gw'orugyendo rwa freewheeling 4A
2.Omushana gw’okuteera ogutari gw’orugyendo nigukira 40kA(8/20);
3.Okushoberwa okusigaireho okurikureeta enkuba. Okushoboorora kimwe embeera eriho hati ngu SPD teine eby‘okukoresa by‘omutaano eby‘okwerinda ebirikukiraho; Ekirugire omu nkoragana ahagati ya SCB na SPD n‘okureeba ngu SPD tiyakwata omuriro kandi n‘okukwatwaho kw‘amashanyarazi g‘enkuba tikuteera.
Omurimo n'obuhango bw'okukozesa
SPD ey’omutaano ey’aheeru erikusharaho neekwatanisibwa omu mubaro aha SPD loop, kandi omunda hati okushoroora omuhanda gw’ekikwato nikikoresibwa kumanya amaani emirundi mikye hati juba kuhenda; Okuteera kw’enkuba y’amaani hati tikurikuteera. Kuhikiiriza omurimo gw‘amaani g‘emirundi mikye hati SPD okurinda omuriro n‘okukwatwaho kw‘enkuba SPD okurinda okugumizamu; Ebintu bya SCB nibikoresibwa omu kurinda SPD loop overcurrent yonka, nari okurinda backup current. Nyabura we otazikoresa omu mikoro endiijo.
Ekintu ekirimus
1. Enkora y‘okuteera ebirikutegyekwa paramita, erikubaasa kuhikiiriza okuhenda okutoorainwe kurabira omu bwire obu;
2. Amashanyarazi agasigaireho ag’amashanyarazi g’okuteera (impulse current) ni makye, agarikubaasa kugyeragyeranisibwa n’aga fiyuzi;
3. Okukoragana kw’amaani maingi, n’amagara g’obuheereza maingi;
4. Enkora ya Micro-broken, obuhango bukye, oburungi ahabw‘okuremwa kw‘amaani kubaasa kumanya SPD;
5.Ebihandiiko ebihikire, kuhikiiriza ebirikwetengyesa kushagika SPD aha rurengo rwa T1, T2 na T3.
6.35mm clamp rail okutaho nikihikiiriza ebyetaago by’okutaho omu nsi yoona.
