SPD-yadu ma ka ilaalin karaan dhammaan noocyada khalkhalka korantada?
SPD-yada waxaa loogu talagalay inay ka ilaaliyaan inta badan kor u kaca ku meel gaarka ah, laakiin waxay leeyihiin xadad ku salaysan qiimeyntooda. Waxaa laga yaabaa inaysan si buuxda uga ilaalin kor u kaca tamarta aadka u sareysa ama weerarada hillaaca tooska ah haddii qalabka aan si habboon loo qiimeyn. Si loo helo ilaalin dhammaystiran, waxaa la isticmaali karaa isku-darka noocyada kala duwan ee SPD.
Farqiga u dhexeeya Nooca 1, Nooca 2 ee Qalabka Ilaalinta SPD
Nooca 1aad ee SPD waxaa loogu talagalay in lagu maareeyo kororka danab ee ku-meel-gaarka ah ee tamarta sare leh, oo badanaa ay sababaan hillaac toos ah. Qalabkan waxaa badanaa lagu rakibaa albaabka ugu weyn ee korontada ee dhismaha, taasoo bixisa ilaalin aasaasi ah oo ka dhan ah xaaladaha daran. Nooca 1aad ee SPDs waxay awood u leeyihiin inay maareeyaan qulqulka korantada ilaa 100 kA ama ka badan, iyagoo adeegsanaya qaybaha ilaalinta tamarta sare sida kuwa hawo-mareenka si loo hubiyo in nidaamka la ilaaliyo inta lagu jiro kororka daran.
Nooca 2aad ee SPD Waxay bixisaa ilaalin qaybaha qaybinta ee nidaamka korontada, iyadoo wax ka qabanaysa qulqulka haraaga ah ee laga yaabo inuu weli jiro ka dib ilaalinta Nooca 1. Iyada oo lagu rakibay guddiyada qaybinta ama guddiyada hoose, Nooca 2 SPDs waxaa loogu talagalay inay maareeyaan qulqulka hawo-mareenka hooseeya, badanaa ilaa 20-40 kA marxalad kasta. Qalabkani wuxuu ka kooban yahay qaybo sida Birta Oxide Varistors (MOVs) ama Tuubooyinka Gaaska ee Soo Daadinta (GDTs) si loo siiyo ilaalin ku filan qalabka ka dib ilaalinta kororka koowaad.
T1+T2 SPD Waxay isku daraysaa faa'iidooyinka Nooca 1aad iyo Nooca 2aad ee SPDs, iyadoo bixinaysa ilaalin dhammaystiran oo loogu talagalay nidaamka korontada oo dhan. Iyadoo lagu rakibayo Nooca 1aad ee SPD albaabka ugu weyn ee korontada si wax looga qabto kororka tamarta sare iyo Nooca 2aad ee SPD ee nidaamka qaybinta si loo ilaaliyo heerka labaad, T1+T2 SPDs waxay hubinayaan difaac adag oo ka dhan ah kororka ballaaran. Habkan isku dhafan wuxuu ku habboon yahay deegaannada khatarta sare leh sida xarumaha xogta, isbitaallada, iyo xarumaha warshadaha, halkaas oo ilaalinta kororka oo dhammaystiran ay muhiim tahay.
Marka loo baahdo qalab ilaalin badan oo koronto (SPDs) si loo ilaaliyo rakibidda, waa muhiim in la isku duwo si ay si sax ah u wada shaqeeyaan. Haddii SPD-yadu ay ka yimaadaan soo-saareyaal kala duwan, waa muhiim in la hubiyo inay is-waafajinayaan. Rakibayaasha iyo soo-saareyaasha aaladaha ayaa ah ilaha ugu wanaagsan ee talo bixinta si loo hubiyo in SPD-yadu si sax ah u shaqayn doonaan iyagoo isku xiran.
Waa maxay Aaladda Ilaalinta Kacsan (SPDs)?
Qalabka Ilaalinta Kororka (SPD), oo sidoo kale loo yaqaan ilaaliyaha kororka, waxaa loogu talagalay inuu ka ilaaliyo aaladaha elektaroonigga ah kororka korantada iyo kororka xad-dhaafka ah ee ku-meel-gaarka ah. Waxay u shaqeysaa sidii qayb muhiim ah oo ka mid ah nidaamka ilaalinta rakibaadda korontada. SPD waxay ku xiran tahay wareegga sahayda korontada ee culaysyada uu ilaaliyo, taasoo la macno ah in loo isticmaali karo heerar kala duwan oo shabakadda sahayda korontada ah. Marka lagu xidho barbar-dhigga, SPD waxay muujisaa caqabad sare xaaladaha caadiga ah. Si kastaba ha ahaatee, marka korontadu ay ku dhacdo koror xad-dhaaf ah, caqabadda SPD way yaraataa, taasoo u oggolaanaysa qulqulka kororka in loo weeciyo qalabka oo laga fogaado qalabka xasaasiga ah. Habkani wuxuu ka caawiyaa ka hortagga waxyeelada qalabka elektaroonigga ah ee qiimaha leh iyadoo la hubinayo in tamarta kororka xad-dhaafka ah si ammaan ah loo maareeyo.
