Qalabka Korontada ee Heer-sare ah waa in uu ilaaliyaa dahaarka aad u wanaagsan inta lagu jiro hawlgalka, Markaa Tijaabooyin Xidhiidh ah oo Xidhiidh ah waa in lafuliyaa bilowga soo saarista qalabka.Tijaabooyinkan waxaa ka mid ah: Tijaabooyin Qalab Ceyriin ah oo ku jira Geedi-socodka Wax-soo-saarka, Tijaabooyin Dhex-dhexaad ah oo ku jira Geedi-socodka Wax-soo-saarka, Tijaabada Tayada iyo Tijaabada Warshada, Isticmaal Tijaabooyin Rakibaadda Goobta, iyo Tijaabooyin Ka-hortagga Dahaarka ee Ilaalinta iyo Hawlgalka Inta lagu jiro Isticmaalka.Marqaatida Qalabka Korontada iyo Tijaabooyinka Ka Hortagga ah ayaa ah labada tijaabo ee ugu muhiimsan.Jamhuuriyadda Dadka ee Shiinaha Xeerka Warshadaha Korontada iyo Xeerka Qaranka: DL/T 596-1996 "Habka Imtixaanka Ka Hortagga ah ee Qalabka Korontada"iyo GB 50150-91 "Qeexaha Tijaabada Bedelida Qalabka Korantada" Sheeg Tusmada iyo Tilmaamaha Tijaabo kasta.
2. Tijaabada Ka Hortagga Dahaarka
Tijaabada Ka-hortagga Dahaarka ee Qalabka Korontadu Waa Cabbiraadda Muhiimka ah ee lagu Xaqiijinayo Shaqada Badbaadada ah ee Qalabka.Imtixaanka ka dib, heerka dahaarka ee qalabka waa la ogaan karaa, khatarta ku jirta dahaarka waxaa la heli karaa waqtigeeda, ilaalinta waa la saari karaa.Haddii ay jirto dhibaato halis ah, waa lagama maarmaan in la beddelo qalabka si looga fogaado khasaaraha aan la soo koobi karin, sida korontadu go'an tahay ama burburka qalabka ee ay keento dahaarka ku guuldareysiga inta lagu jiro hawlgalka.
Tijaabooyinka Ka Hortagga Dahaarka waxa loo qaybin karaa laba qaybood: Midi waa Tijaabo Aan Burbursanayn ama Tijaabo sifada dahaadhka, Kaas oo tilmaamaya qiyaaso astaamo kala duwan oo lagu cabbiro Voltage hoose ama habab kale oo aan waxyeelo u gaysan doonin dahaarka, oo ay ku jiraan iska caabbinta Cabbiraadda Xakamaynta Tangent Dielectric Loss Tangent, iwm. Kadibna go'aami haddii dahaarka uu leeyahay wax cillado ah.Tijaabooyinku waxay muujiyeen in habkani yahay mid faa'iido leh, laakiin aan loo isticmaali karin si la isku halleyn karo loo ogaado xoogga koronto ee dahaarka.Midda kale waa tijaabo wax baabi'in ah ama tijaabo cadaadis.Voltage-ka lagu Codsaday Tijaabada ayaa ka Sarraysa Korantada Shaqeysa ee Qalabka, iyo Shuruudaha Tijaabada Dahaarka ayaa aad u adag.Gaar ahaan, waxaa jirta khatar weyn oo ah soo bandhigida iyo ururinta cilladaha, iyo in la hubiyo in dahaarka uu leeyahay xoogaa koronto ah oo gaar ah, oo ay ku jiraan DC adkaysiga korantada, Isgaadhsiinta adkaysiga korantada, iwm. Khatarta adkaysiga u adkeysiga tijaabada korantada waa in ay sababi doonto qaar ka mid ah Waxyeelo Soo Gaadhay Dahaarka
3. Tijaabada wareejinta Qalabka Korontada
Si loo daboolo baahiyaha Injineerinka Rakibaadda Korontada iyo Tijaabooyinka Beddelka Qalabka Korontada, oo kor loogu qaado Horumarinta iyo Codsiga Teknolojiyadda Cusub ee Tijaabooyinka Beddelka Qalabka Korontada, Heerka Qaranka GB 50150-91 Tilmaamaha Tijaabooyinka Kala Duwan.Marka lagu daro Qaar ka mid ah Tijaabooyinka Ka Hortagga Dahaarka, Tijaabooyinka Beddelka Qalabka Korontada sidoo kale waxaa ku jira Tijaabooyin Sifadeed, sida Transformer DC Resistance iyo Ratio Experiments, Tijaabada Iska caabbinta Wareegga Breaker Loop, iwm.
4. Mabaadi'da Aasaasiga ah ee Tijaabada Ka Hortagga Dahaarka
4.1 Tijaabada iska caabbinta dahaarka Tijaabada iska caabbinta waa shayga ugu balaadhan ee loo isticmaalo uguna fudud ee tijaabada dahaarka ee qalabka korantada.Qiimaha caabbinta dahaarka ayaa si wax ku ool ah u muujin kara cilladaha dahaarka, sida wadarta qoyaanka, wasakhowga, kulaylka daran iyo gabowga.Qalabka Inta badan loo isticmaalo Tijaabinta iska caabbinta dahaarka waa Tijaabaha iska caabbinta dahaarka
Tijaabooyinka iska caabbinta dahaarka (Isolation Resistance Tijaabayaasha) Sida caadiga ah waxay leeyihiin noocyo ay ka mid yihiin 100 Volts, 250 Volts, 500 Volts, 1000 Volts, 2500 Volts, iyo 5000 Volts.Tijaabada iska caabbinta dahaarka waa in loo adeegsadaa si waafaqsan DL/T596 "Nidaamka Tijaabada Ka Hortagga ah ee Qalabka Korontada".
4.2 Tijaabada Hadda
Korantada Tijaabada Caabbinta Dahaarka Guud ee DC wuu ka hooseeyaa 2.5KV, kaas oo aad uga hooseeya Voltage-ka shaqeeya ee Qalabka Korontada qaarkood.Haddii aad u malaynayso in cabbiraadda korantada ee tijaabiyaha iska caabbinta dahaarka uu aad u hooseeyo, waxaad cabbiri kartaa daadinta hadda ee qalabka korontada adiga oo ku daraya korantada sare ee DC.Qalabka sida caadiga ah loo isticmaalo ee lagu cabbiro qulqulka hadda waxa ka mid ah Beddeleyaasha Tijaabada Voltage-sare iyo koronto-dhaliyayaasha-sare ee DC.Marka qalabku leeyahay cillado, dareeraha hadda ku hoos jira korantada sarreeya aad ayuu uga weyn yahay kan ku hooseeya korantada hooseeya, taas oo ah, iska caabbinta dahaarka ee ku hoos jira korantada sarreeya aad ayuu uga yar yahay kan ku hooseeya korantada hooseeya.
Ma jiro farqi badan oo u dhexeeya qulqulka hadda iyo iska caabbinta dahaarka ee qalabka cabbiraadda tijaabada korantada ee caafimadka, laakiin cabirka hadda ee daadinta ayaa leh sifooyinka soo socda:
(1) Tijaabadu Voltage aad ayuu uga sarreeyaa kan tijaabiyaha iska caabbinta dahaarka.Cilladaha Dahaarka laftiisa ayaa si fudud loo soo bandhigaa, waxaana la heli karaa cilladaha isku-dhafka qaarkood oo aan la gelin.
(2) Cabbiraadda xidhiidhka ka dhexeeya qulqulka hadda jira iyo korantada la dabaqay waxay caawisaa in la falanqeeyo noocyada cilladaha dahaarka.
(3) Microampere-ka loo isticmaalo Cabbiraadda hadda socda ayaa ka saxsan Tijaabada iska caabbinta dahaarka.
4.3 DC U adkaysta Tijaabada Korantada
Tijaabada korantada ee adkeysiga DC ayaa ka sareysa
Isgaadhsiinta U adkaysiga Tijaabada Korantada Mararka qaarkood waxay ka dhigtaa daciifnimada qaar ka mid ah dahaarka mid aad u caan ah.Sidaa darteed, waa lama huraan in la sameeyo tijaabooyin ku saabsan iska caabbinta dahaarka, heerka nuugista, qulqulka hadda iyo luminta tamarta ka hor tijaabada.Haddii Natiijadu tahay mid lagu qanco, Isgaadhsiinta U adkaysiga Tijaabada Korantada waa la samayn karaa.Haddii kale, waa in wax laga qabtaa waqtiga, iyo isgaadhsiinta u adkeysiga tijaabada korantada waa in la sameeyaa ka dib marka bartilmaameed kasta uu u qalmo si looga fogaado burburka aan loo baahnayn.
4.5 Tijaabada Khasaaraha Dielectric Tgδ
Sababta Khasaarida Dielectric Tgδ waa mid ka mid ah yoolalka aasaasiga ah ee ka tarjumaya waxqabadka dahaarka.Qodobka Khasaaraha Dielectric Tgδ wuxuu ka tarjumayaa cabbirka sifada ee lumista dahaarka.Waxay si firfircoon u ogaan kartaa dahaadhka guud ee qalabka korantada ee ay saameeyeen qoynta, xumaanshaha, iyo xumaanta, iyo sidoo kale cilladaha maxalliga ah ee qalabka cabbirka yar.
Isbarbardhigga Caafimaadka U-adkeysiga Tijaabada Korantada ee Caabbinta Dahaarka iyo Bixinta Tijaabooyinka Hadda, Factor Khasaare Dielectric Tgδ Waxay Leedahay Faa'iidooyin Muhiim ah.Waxba kuma laha Voltage-ka Tijaabada, Cabirka Tusaalaha Tijaabada iyo Qodobo kale, Wayna fududahay in la kala saaro Isbeddelka Dahaarka ee Qalabka Korontada.Sidaa darteed, Factor The Dielectric Loss Factor Tgδ waa Mid ka mid ah Tijaabooyinka ugu Muhiimsan ee Tijaabada Dahaarka ee Qalabka Korontada-sare.
Sababta Khasaarida Dielectric Tgδ waxay noqon kartaa mid faa'iido leh si loo helo cilladaha soo socda ee soo socda:
(1) Qoyaanka;(2) Geli Kanaalka Hagaajinta;(3) Dahaarku waxa uu ka kooban yahay xumbo-xabo oo bilaash ah, iyo dahaarka dahaadh iyo qolof;(4) Dahaarku waa wasakh, xumaaday, iyo gabowga.
