Waa maxay shuruudaha farsamada ee guddiga dahaarka SMC

Guddiga dahaarka SMC waa alaab aad loo jecel yahay guddiga dahaarka. Macaamiisha doonaya inay iibsadaan, waxa ugu horreeya ee ay rabaan inay fahmaan waa shuruudaha farsamada. Kaliya marka ay ogaadaan kuwan waxay samayn karaan doorasho sax ah. Marka xigta, aan raacno soosaarayaasha xirfadleyda ah si aan u fahanno shuruudaha farsamada ee guddiga dahaarka SMC.

1. caabbinta dahaarka iyo iska caabinta

Iska caabintu waa isdhaafsiga habdhaqanka, iska caabintuna waa caabbinta halbeeg kasta. Mar kasta oo maaddadu ay yaraato, way sii badanaysaa iska caabinteeda, labadooduna waxay ku jiraan xidhiidh is-dhaafsi ah. Qalabka dahaadhka ah, had iyo jeer waa la jecel yahay in la helo caabbinta ugu sareysa ee suurtogalka ah.

2, ogolaanshaha qaraabada ah iyo tangent qasaaraha korontada

Alaabta dahaadhka ahi waxay leeyihiin laba adeegsi: dahaarka qaybaha kala duwan ee shabakada korantada iyo dhexdhexaadiyaha capacitor (keydinta tamarta). Midka hore wuxuu u baahan yahay ogolaansho yar oo qaraabo ah, kan dambe wuxuu u baahan yahay ogolaansho qaraabo weyn ah, labaduba waxay u baahan yihiin taangiga khasaaraha dielectric yar, gaar ahaan qalabka dahaadhka ah ee loo isticmaalo soo noqnoqoshada sare iyo danab sare, si loo yareeyo khasaaraha dielectric yar, labaduba waxay u baahan yihiin xulashada Insulating. walxo leh taangti yar oo lumis dielectric.

3, burburka tamarta iyo korontada

Maaddada dahaarka ayaa waxyeello u geysata meel koronto oo xoog leh hoosteeda, waxayna lumisaa waxqabadka dahaarka waxayna noqotaa xaalad dhaq-dhaqaaq ah, oo loo yaqaan burbur. Korontada wakhtiga burburka waxa loo yaqaan burburka danab (power dielectric). Awoodda korontodu waa tirada danabku marka uu burburku ku yimaado xaaladaha caadiga ah iyo masaafada u dhaxaysa labada elektarood ee xanbaarsan danabka la dabaqay, taas oo ah burburka danabkiiba dhumucdiiba. Marka laga hadlayo walxaha dahaarka, guud ahaan, kororka burburka iyo xoogga korantada, ayaa ka sii wanaagsan.

4, xoogga xajinta

waa culayska xajiska ah ee muunadku ku sido tijaabada xajinta. Waa tijaabo si ballaaran loo isticmaalo oo wakiil ka ah sifooyinka farsamada ee alaabta daaha.

5. Iska caabin gubasho

Waxa loola jeedaa awoodda walxaha dahaadhka ah si ay iskaga caabiyaan gubashada marka ay taabtaan ololka ama ka hortagga gubasho joogto ah marka ay ka baxaan ololka. Isticmaalka sii kordhaya ee alaabta dahaadhka ah, shuruudaha caabbinta ololkooda ayaa muhiim ah. Dadku waxay wanaajiyeen oo ay wanaajiyeen caabbinta ololka ee alaabta dahaadhka iyada oo loo marayo habab kala duwan. Markasta oo ay sare u kacdo iska caabbinta gubashada, ayaa badqabka sii wanaagsanaanaya.

6, iska caabin arc

Marka la eego xaaladaha tijaabada ah ee joogtada ah, awoodda walxaha dahaadhka ah ee u adkeysiga saameynta arc ee korkeeda. Tijaabada, tamarta sare ee AC iyo hadda yar yar ayaa la doortay, iyo saamaynta arc ee tamarta sare ee u dhaxaysa labada elektarood ayaa loo isticmaalaa si loo go’aamiyo caabbinta arc ee walxaha dahaarka wakhtiga loo baahan yahay walxaha dahaarka si ay u sameeyaan lakab korantada. . Qiimaha waqtiga oo weyn, ayaa ka sii wanagsan iska caabbinta arc.

7, shahaadada shaabadeynta

Way fiicantahay in la xidho oo la go’doomiyo tayada saliidda iyo biyaha.
