Kabatar da Tashar Karamin Iya

Lalace da karamin kwarewa yana aiki mai mahimmanci wajen bayar da kwarewa daga tashar karamin kwarewa zuwa jamiyar duk da suka sa. Yana tafiya maza da tsaye daga faduwar zuwa na biyu. A cikin al'adu, lalace da karamin kwarewa yana da kandace mai zurfi na musamman a cikin gadi. Amma, hawa yana aiki a matsayin masanin ko mutanen tsari a kan kandacen, wanda yake da muhimmanci wajen kare karamin kwarewa da bayar da shi da zafi da kyau.

Don dalilai zaɓe, ana iya da yanayin da ya fi girma a kan lalace da karamin kwarewa da tsakiyar zamani. Ana amfani da turawar karamin kwarewa don inganta kandacen lalace. Wannan turawa suna ban samun feret talifin don ba kandacen lalace zafi da kyau, ta haka za ta ba da zama da karamin kwarewa da zafi da kyau. Idan an yi karamin kwarewa da kadan da ke kusa da karamin kwarewa, ana amfani da karamin kwarewa na kadan da tsaye (HVDC) a lalacen saboda muhimman abubuwan da suke a kan kare karamin kwarewa da zafi da kyau.

Makasidancewar Lalace da Karamin Kwarewa

Zamantakewar lalace da karamin kwarewa yana nufin makasidancewar da suka da su. Lallace da karamin kwarewa yana da makasidancewar uku: tasirin, inductance, capacitance, da shunt conductance. Wannan makasidancewar suna haɗa a kan gadi na lalace, saboda haka ana kiran su da sunan makasidancewar haɗa. Har da wannan makasidancewar yana da muhimmanci wajen siffar da tafiyar da karamin kwarewa, wajen kare magance karamin kwarewa, kada kwarewa, da zafi da kyau.

Tasiri da inductance suna haɗa don bincike series impedance, amma capacitance da conductance suna haɗa don bincike shunt admittance. A nan, za a bayyana wasu daga cikin muhimman makasidancewar lalace da karamin kwarewa:

Line Inductance

Idan kudin yana ƙarya a kan lalace, yana haɗa da flux mai hawa. Idan kudin a kan lalace yana ƙarin, flux mai hawa yana ƙarin. Wannan ƙarin da yake a kan flux mai hawa yana haɗa da electromotive force (emf) a kan ci gaba. Tsayen emf yana da ita da rarrabe da ƙarin da yake a kan flux mai hawa. Emf da aka haɗa a kan lalace yana dogara ƙudin da yake a kan kandace, wanda ake kira da sunan line inductance.

Line Capacitance

A lalacen, hawa yana aiki a matsayin mutanen tsari. Wannan mutanen tsari yana haɗa da capacitor a kan kandacen, wanda yana da abili da za su iya adadin kwarewa mai hawa, kuma yana kasance capacitance na lalace. Capacitance na kandace yana nufin daraja daga adadin kwarewa da koyar da karamin kwarewa a kan kandace.

A lalacen da ke kusa, adadin capacitance yana iya kasance da ma a duba. Amma, a lalacen da ke kusa, yana zama daya daga cikin muhimman makasidancewar. Yana haɗa da muhimman abubuwan da suke a kan tafiyar, kada kwarewa, power factor, da zafi da kyau.

Shunt Conductance

Hawa yana aiki a matsayin mutanen tsari a kan kandacen lalace. Idan an kara karamin kwarewa na kadan a kan kandacen, saboda nasabon da suka da su a kan mutanen tsari, yana ƙarya kudin a kan mutanen tsari. Wannan kudin yana kira da sunan leakage current. Tsayen leakage current yana da ita da al'amuran zamani da kuma al'amuran yankin kamar tsirrai da abubuwan da suka fitowa a kan kofin. Shunt conductance yana nufin ƙudin leakage current da yake a kan kandacen. Yana haɗa a kan gadi na lalace, yana da alamar "Y", kuma ana kira shi a Siemens.

Zamantakewar Lalace da Karamin Kwarewa

Tambayar da zamantakewar lalace da karamin kwarewa yana nufin karkashin makasidancewar da suka da su, kamar karamin kwarewa na biyu, kudin na biyu, power factor na biyu, karamin kwarewa da ke kasa a kan lalace, tafiyar, kada kwarewa, da kuma hakkin karamin kwarewa a lokacin da za a tabbata da lokacin da za a faru. Wannan karkashin yana da muhimmanci wajen tattalin tushen karamin kwarewa. Daga cikin waɗannan, za a bayyana wasu daga cikin muhimman makasidancewar a nan:

Kada Kwarewa

Kada kwarewa yana nufin farko da tsayen karamin kwarewa a kan biyu da biyu a kan lalace da karamin kwarewa.

Muhimman Abubuwa

Admittance yana nufin muhimman paramitan karmi mai kira da abili da ci gaban karamin kwarewa na kadan, ko kuma tafiyar lalace da karamin kwarewa, don bayar da kudin mai hawa. Unitoshin SI na shi shine Siemens, kuma ana kiran shi da alamar "Y". Ba da yake, yadda ake fiye admittance yana nuna cewa ci gaban karamin kwarewa na kadan, ko kuma lalace da karamin kwarewa, ba ake da takaitaccen kudin mai hawa, ta haka yana iya ƙarya kudin mai hawa da zafi da kyau.

Na gode, impedance yana nufin reciprocal ta admittance. Yana kira da takaitaccen kudin da lalace da karamin kwarewa yake a kan kudin mai hawa. Idan kudin mai hawa yana ƙarya a kan lalace, impedance yana kira da muhimman abubuwan da suke a kan tasiri, inductive reactance, da capacitive reactance, wanda suka haɗa da takaitaccen kudin kudin. Impedance yana kira shi a ohms, kuma ana kiran shi da alamar "Z". Yadda ake fiye impedance yana nuna cewa yana da takaitaccen kudin kudin mai hawa a kan lalace, wanda yana iya kare karamin kwarewa da kasa da kudin mai hawa da kasa.
