Pankhani yaukadaulo wamagetsi, ma transfoma amagwira ntchito yofunika kwambiri pakufalitsa ndi kugawa mphamvu zamagetsi. Pakati pa mitundu yosiyanasiyana ya ma transformer, ma transformer amakono (CTs) ndi ofunikira kuti athe kuyeza ndi kuyang'anira zamakono mu machitidwe a mphamvu. Chigawo chachikulu cha zipangizozi ndi bolodi losindikizidwa (PCB), lomwe liri pakatikati pa kugwirizana kwa magetsi ndi ntchito ya transformer yamakono. Nkhaniyi ikufotokoza za kufunika kwaMa PCBm'ma transformer amakono, kuyang'ana mapangidwe awo, ntchito, ndi zotsatira zake pa ntchito yonse ya chipangizocho.
Kumvetsetsa Zosintha Zamakono
Tisanafufuze zenizeni za ma PCB, ndikofunikira kumvetsetsa kaye kuti thiransifoma yamakono ndi chiyani. Transformer yamakono ndi thiransifoma yomwe imapanga panopa yomwe imachepetsedwa mofanana ndi yomwe ili mu dera loyamba. Izi zimapangitsa kukhala otetezeka kuyeza mafunde akulu, omwe angakhale owopsa kuyeza mwachindunji. Ma transfoma apano amagwiritsidwa ntchito kwambiri pamakina amagetsi ndi njira zodzitchinjiriza kuyang'anira magwiridwe antchito a katundu wamagetsi ndi ma relay achitetezo.
Udindo wa PCB mu thiransifoma yamakono
Bolodi losindikizidwa(PCB) ndi bolodi lathyathyathya lopangidwa ndi zinthu zotsekereza zokhala ndi njira zowongolera kapena zosindikizidwa. Njirazi zimagwirizanitsa zigawo zosiyanasiyana zamagetsi kuti athe kugwira ntchito pamodzi. Mu transformer yamakono, PCB imagwira ntchito zingapo zofunika:
1. Kulumikizana kwa Magetsi
Ntchito yayikulu ya PCB mu thiransifoma yamakono ndikupereka nsanja yolumikizira magetsi. PCB imagwirizanitsa ma windings oyambirira ndi achiwiri a transformer, komanso zigawo zina monga resistors, capacitors, ndi diode. Kulumikizana kumeneku ndikofunikira kuti muyezedwe molondola komanso moyenera ntchito ya transformer.
2. Kusintha kwa Signal
Ma transfoma apano nthawi zambiri amafunikira mawonekedwe azizindikiro kuti zitsimikizire kuti zotulukazo ndizoyenera kuyeza ndi kuyang'anira machitidwe. PCB imatha kukhala ndi magawo osiyanasiyana opangira ma siginecha, monga ma amplifiers ndi zosefera, kupititsa patsogolo mtundu wa chizindikirocho. Kukonza uku ndikofunikira pamapulogalamu omwe amafunikira kulondola kwambiri, monga ma relay otetezedwa ndi zida zama mita.
3. Kutentha Kwambiri
Transformers amapanga kutentha panthawi yogwira ntchito, ndipo kasamalidwe kabwino ka kutentha ndikofunika kwambiri kuti apitirize kugwira ntchito komanso moyo wawo wonse. PCBs akhoza kupangidwa ndi mbali matenthedwe kasamalidwe, monga zomangira kutentha kapena vias matenthedwe, dissipate kutentha kutali zigawo tcheru. Izi ndizofunikira makamaka kwa osinthira apano, pomwe kutentha kwambiri kungayambitse miyeso yolakwika kapena kulephera.
4. Compact Design
Kuphatikiza zigawo pa PCB kumapangitsa kuti pakhale mawonekedwe ophatikizika amakono a thiransifoma. Izi ndizopindulitsa makamaka pamapulogalamu omwe malo ali ochepa, monga switchgear kapena ma control panel. PCB yopangidwa bwino imatha kuchepetsa kukula kwa transformer ndikusunga magwiridwe ake, ndikupangitsa kuti ikhale yosavuta kuyiyika m'malo osiyanasiyana.
5. Kudalirika ndi Kukhalitsa
Ma PCB amapangidwa ndi zida zolimba zomwe zimatha kupirira zovuta zachilengedwe. Kukhazikika kumeneku ndikofunikira kwa ma transfoma apano, chifukwa nthawi zambiri amatumizidwa panja kapena m'mafakitale. PCB yodalirika imatsimikizira kuti thiransifoma yamakono imagwira ntchito bwino pa moyo wake wonse, kuchepetsa kufunika kokonzanso ndi kusinthidwa.
Pangani ZamakonoTransformer PCB
Mapangidwe a thiransifoma yamakono PCB amafunikira kulingalira zinthu zingapo kuti zitsimikizire kuti zikuyenda bwino. Nazi zina mwazinthu zazikulu zomwe mainjiniya ayenera kuziganizira:
1.Kusankha Kwachigawo
Kusankha zigawo zoyenera ndizofunikira kwambiri pakugwira ntchito kwa transformer yamakono. Mainjiniya ayenera kusankha zinthu zomwe zitha kuthana ndi milingo yomwe ikuyembekezeka komanso chilengedwe. Izi zikuphatikiza kusankha zopinga zoyenera, ma capacitor, ndi zolumikizira zomwe zimatha kupirira kupsinjika kwamagetsi ndi kutentha.
2. Kamangidwe ndi Njira
Mawonekedwe a PCB akuyenera kukonzedwa bwino kuti achepetse kusokoneza ndikuwonetsetsa kuti ma siginecha akuyenda bwino. Kutsata koyenera ndikofunikira kuti muchepetse inductance ndi capacitance, zomwe zimakhudza kulondola kwa kuyeza kwapano. Kuphatikiza apo, kuyika kwazinthu kuyenera kuthandizira kuyendetsa bwino kwamafuta.
3. Kuyesedwa ndi Kutsimikizira
Mapangidwe a PCB akapangidwa, amayenera kuyesedwa mwamphamvu kuti atsimikizire momwe amagwirira ntchito. Izi zikuphatikiza kuyang'ana kupitilira kwamagetsi, kukhulupirika kwa ma siginecha, ndi magwiridwe antchito amafuta. Kuyesa kumatsimikizira kuti thiransifoma yamakono idzagwira ntchito modalirika pansi pa zochitika zenizeni.
Pomaliza
Mwachidule, bolodi losindikizidwa (PCB) ndi gawo lofunikira pa zosintha zaposachedwa ndipo limatenga gawo lofunikira pakugwira ntchito ndi magwiridwe antchito awo. Kuchokera pakupereka maulumikizidwe amagetsi mpaka kuwongolera ma siginecha ndi kasamalidwe ka kutentha, ma PCB ndi gawo lofunikira pakugwiritsa ntchito zidazi. Pamene ukadaulo ukupitilirabe patsogolo, mapangidwe ndi kupanga ma PCB osinthira apano apitilizabe kusinthika, zomwe zimapangitsa kuti pakhale njira zoyezera komanso zodalirika zomwe zilipo. Kwa mainjiniya ndi akatswiri pazaumisiri wamagetsi, ndikofunikira kumvetsetsa kufunikira kwa ma PCB mu zosintha zapano chifukwa zimakhudza mwachindunji magwiridwe antchito amagetsi komanso chitetezo chamagetsi.
