Sida loo doorto soosaaraha qalabka difaaca ee SPD
8 qodob oo muhiim ah oo laga iibsado Shiinaha qalab koronto ilaalin ah
Waxaan LSP soo saare Shiinaha ah tan iyo 2010, waxaan diirada saareynaa dadaalkeena ku saabsan horumarinta ilaalinta sare iyo soo saarida AC DC PV aaladaha kor u kaca, waxaan ku dadaalnaa inaan ugu adeegno macaamiisheena alaab tayo sare leh.
Haddii aad tahay soo dejiye qalabka korontada, wakiil, qaybiyaha, ganacsade ama tafaariiqle, marka aad iibsaneyso AC iyo DC ama PV SPDs (aaladaha kor u kaca), waa inaad ogaataa 8 qodob oo muhiim u ah iibsashada aaladda bedbaadada korantada ee beddesha (SPD) ee Shiinaha

(1.1) Noolaha Birta Oxide - MOV
Maaddaama ay tahay udub dhexaad gudaha SPDs, looma baahna in la sheego, tayada SPD badanaa waxay kuxirantahay tayada kala duwanaanta. Sida iska cad isticmaal tayada tayada leh ee 'MOV' oo aad uga muhiimsan, waxaa jira noocyo badan oo caan ah oo kala duwan oo loo yaqaan 'oxide oxide' xulashada sida EPCOS / TDK, Littelfuse, Keko, Varsi…

Ka dib markii la xushay varistor oksida biraha ah (MOV), waxaan wali u baahan nahay inaan fiiro gaar ah u yeelano sida loogu dhejiyo guryaha SPD. waxaa jira laba hab:
A. Kala-soocida daboolan kala-soocida, badanaa lagu daboolay midab cagaaran ama buluug ah huur-caddeyn
B. Qaar ka mid ah soosaarayaasha SPDs waxay adeegsadaan kala duwanaansho qaawan oo leh xiriiriye, waxay u baahan tahay adeegsiga cusbada epoxy si loogu daro. Waxaad ubaahantahay inaad ogaatid cusbada epoxy-ka uusan aheyn mid deegaanka u wanaagsan, sumcadda caanka ah ee SPDs ma sameyso intaas wixii ka badan.
C. Si loo yareeyo kharashka, qaar ka mid ah soosaarayaasha SPDs waxay adeegsadaan kala-duwanaansho yar si ay u beddelaan 34S varistor, aan tusaale u soo qaadanno, haddii aad rabto inaad iibsato SPD tayo leh, rajeeyaa in dheecaanka Magaciisu hadda yahay (8 / 20μs) In = 20kA iyo dheecaanka ugu sarreeya ee hadda jira (8 / 20μs) Imax = 40kA, waa inuu adeegsadaa 34S varistor (34 macnaheedu waa 34mm; "S" macnaheedu waa laba jibbaaran), laakiin waxay adeegsadaan kala duwanaansho yar sida 20D, 25D, 32D si loogu beddelo 34S.

(1.3) Naqshadaynta qaabdhismeedka gudaha
Noocyo badan oo ah noocyada 'SPDs' ee suuqa dhexdiisa, waxaad arki doontaa inay u badan yihiin laba qaab naqshad qaab-dhismeed gudaha ah oo qaab moodal ah loo adeegsan karo: Dehn style iyo OBO style
Qaabka OBO:
marka kororka weyn ee hadda socda, ballaca qaybta isku xirnaanta biraha ay aad u cidhiidhi tahay, uma adkeysan karto 40kA kororka hadda.
Qaabka Dehn:
Thanks to design macquul ah, waxay u adkeysan kartaa Imax = 40kA kororka hadda.
(1.4) Guryaha caaga ah
wax tayo leh waa PA66 ama nylon ka hortagga dabka.
(1.5) Qaybaha birta, maaddada birta aasaasiga ah waa inay ahaadaan biro qabow, ma aha bir.
Qaabka OBO wuxuu u adeegsadaa qaybaha birta birta ah:
Qaabka Dehn wuxuu u adeegsadaa qaybo bir ah oo qabow:
(1.6) Agab ilaalinta deegaanka
Warshada qaar waxay isticmaashaa cusbada epoxy-ka si ay u xirto. Dheecaanka 'Epoxy resin' waa urayaa mana u fiicna ilaalinta deegaanka iyo caafimaadka.
Waxaan isticmaalnaa kala-soocida dahaarka leh, uma baahnid cusbada epoxy, waxay ugafiican tahay ilaalinta deegaanka.
2. Qalabaynta soosaarka
Qaybaha birta waxay ku xirmaan MOV (varistor) waa inay ahaadaan kuwo alxanka lagu kalsoonaan karo. haddii alxanka gacanta, waxaa si fudud u dhici Alxan ku filnayn. Marka alxanka tooska ahi wuxuu ilaalin karaa joogtaynta tayada wax soo saarka. https://www.youtube.com/watch?v=RHwNJv8hobE

8. Xidhmada
Nooc kastoo warshad ama OEM ah, soo saaraha waa inuu bixiyaa shaambad sax ah (serigraphy), xirmo (kartoonka iyo sanduuqa), warqad ama buug elektaroonig ah (tilmaamaha rakibidda)
Sida loo doorto soosaaraha qalabka difaaca ee SPD, Kuwani 8 qodob oo muhiim u ah iibsashada qalabka ka-hortagga kororka ee ka yimaada Shiinaha, waxaan rajeyneynaa inay waxtar leedahay.
Waxaan nahay shirkad qoys oo ka socota isla markaana siinayna aaladaha ka hortagga kor u kaca (SPD) adduunka in ka badan 10 sano. Waxaan leenahay cilmi baaris & horumarin, wax soo saar, taageero farsamo iyo shaybaarka tijaabada sidoo kale.
LSP waxaa loo soo saarey oo keliya guryaha la degan yahay iyo kuwa aan deganeyn, laakiin sidoo kale loogu talagalay codsiyada warshadaha sida dhuumaha saliidda, dhuumaha gaaska, sawir qaadayaasha, saldhigyada korantada iyo jidadka tareennada. Wax soo saarkeenu wuxuu ka ilaaliyaa kor u kaca teknoolojiyadaha kala duwan, mashiinnada, qalabka iyo qalabka adduunka oo idil.
Waxaan sidoo kale soo saareynaa oo soosaarnaa aaladaha kormeerka dahaarka (IMD) ee shabakadaha bixinta korontada ee go'doonsan. Waxaan bixinaa xal dhammaystiran oo adag oo A-Z ah oo loogu talagalay kormeerka xaaladda dahaarka ee isbitaalada, warshadaha iyo codsiyada gaarka ah.
Kama dhigno inaan wax walba qaban karno, Haddii aan wax su'aalo ah iyo soo jeedin ah oo ku saabsan waxyaabaha SPDs ah, kooxdeenna farsamo yaqaanno ah ayaa ku farxi doona inay ka jawaabaan su'aalahaaga oo ay kuu helaan wax soo saarka kuugu habboon.
