Farko Da Kasa na Farkon Yawan Zama (TRV) a Lamsar Tashin Karfi
Idan yakin da ya faruwa a lamsar tashin karfi daga 100 mita zuwa kabiluwa, ana bukatar fadada (CB) don in bace yakin da ya faruwa a lamsar. Ingantaccen yakin da ya faruwa ta fadada zai iya haifar da farkon yawan zama (TRV) da tsarin zama mai yawa, wanda yake da ma'ana mai furke da sawtooth. Wannan abu yana faruwa saboda yawan zama mai gaba da suka hada a kan lamsar da suka hankali bayan fadada da yakin da ya faruwa.
Abubuwa Mafi Yawanci A Gaba Da Bace Yakin Da Ya Faruwa
Yawan Zama Mai Gaba Da Tsarin Sawtooth:
Idan fadada ta bace yakin da ya faruwa a kan SLF, za a faruwa yawan zama mai gaba saboda yawan inganta da yawan zama. Waɗannan yawan zama zai haifar da TRV mai tsari mai yawa, wanda zai iya samun shi a cikin tsarin sawtooth ko triangular.
Tsarin sawtooth yana faruwa saboda traveling waves da suka hada a kan lamsar tashin karfi da suka hankali bayan fadada da yakin da ya faruwa. Har canza suka haifar da yawan zama mai furke da TRV, wanda zai iya samun kabiluwa da wurare a kan tsarin yawan zama.
Yawan Zama a Kofin Nau'in Kirkiro:
A kofin nau'in kirkiro na fadada (kofin da aka saka da sauran tashin kirkiro), yawan zama a kofin fadada zai bazu a kan tasirin sauran tashin kirkiro, wanda yana da ma'ana tasirin transformer. Wannan rawa yana haifar da yawan zama a kan tasirin sauran tashin kirkiro (misali 50 Hz ko 60 Hz) a kan kofin sauran tashin kirkiro.
Yawan zama a kan tasirin sauran tashin kirkiro yana faruwa saboda inganta mai yawa a kan tsarin kofin idan yakin da ya faruwa ta bace, wanda yake da rawa mai yawa a kan tashin kirkiro. Wannan yawan zama zai maza har shekarar lokaci da tashin kirkiro ta shiga tasirin.
Yawan Zama a Kofin Lamsar:
A kofin lamsar na fadada (kofin da aka saka da lamsar tashin karfi), yawan zama a kofin fadada zai zama a kan tasirin kasa ba a baya idan yakin da ya faruwa ta bace. Wannan rawa zai haifar da yawan zama, amma a nan yana da tsarin sawtooth (triangular) saboda traveling da reflecting waves a kan lamsar.
Kofin lamsar zai iya samun da ita a kan distributed parameter circuit da yawan maza mai yawa. Hankan hankalin bayan fadada da yakin da ya faruwa zai haifar da yawan zama, wanda zai iya samun tsarin sawtooth. Tasirin waɗannan yawan zama yana da ma'ana mai yawa da tasirin sauran tashin kirkiro, wanda yake da ma'ana lafiya da darajar da waves suka hada da karshe bayan fadada da yakin da ya faruwa.
Tasirin Kofin Lamsar
Kofin lamsar zai iya samun da ita a kan distributed parameter circuit da yawan maza mai yawa, misali resistance, inductance, da capacitance per unit length. Wannan model na iya taimakawa wajen fahimtar yawan hada da hankalin bayan waɗannan waves. Abubuwan muhimman da suka duba wannan model sun hada da:
Propagation Delay: Lokacin da wave ya hada a kan kofin fadada zuwa yakin da ya faruwa ba ta hura.
Reflection Coefficient: Darajan da aka samun da reflected wave amplitude zuwa incident wave amplitude, wanda yana da ma'ana imbalancin impedance bayan lamsar da yakin da ya faruwa.
Attenuation: Yawan maza da wave ya samu a kan lokacin da ya hada a kan lamsar, wanda yana da ma'ana resistance da conductance na lamsar.
TRV Waveforms Across Circuit Breaker Terminals and Line Side
TRV waveforms da ake samun a kan kofin fadada da kofin lamsar zai iya samun da ita haka:
Kofin Nau'in Kirkiro (Circuit Breaker Terminal):
Yawan zama zai bazu a kan tasirin sauran tashin kirkiro, wanda yake da rawa mai yawa a kan tasirin sauran tashin kirkiro.
Rawa yana da ma'ana mai yawa da yawan zama mai gaba a kan kofin lamsar.
Kofin Lamsar (Circuit Breaker Terminal):
Yawan zama zai zama a kan tasirin kasa, wanda yake da rawa mai gaba da tsarin sawtooth (triangular).
Tsarin sawtooth yana faruwa saboda yawan inganta a kan yawan zama da suka faruwa saboda traveling da reflecting waves a kan lamsar.
Visual Representation of TRV Waveforms
Wani rubutu mai yawa da ke samun TRV waveforms a kan kofin fadada da kofin lamsar zai iya nuna:
Kofin Nau'in Kirkiro TRV: Tsarin da ya faruwa a kan tasirin sauran tashin kirkiro, da rawa mai yawa a kan tasirin sauran tashin kirkiro.
Kofin Lamsar TRV: Tsarin da ya zama a kan tasirin kasa, da kabiluwa da wurare mai gaba, wanda suka samun tsarin sawtooth ko triangular.
