Mi shi ne Dead Short?

Dead short yana da fitaccen kabilan mai soro wanda ya fara karamin kasa a kan hanyar ba da tsari na gaba zuwa wani wurin da ba ake nufin. Wannan ya haɗa da karamin kasa mai yawa a kan kabilan, wanda zai iya gafara kayayyakin ko haɗa da karamin kasa mai yawa wa mutane da ke cikin jirgin.

Dead short ita ce mafi karfi a taimaka da koyarwa saboda karamin kasa ya faru a kawo da koyarwa ta faru.

Yana faru domin babban wasu masu karamin kasa da karamin kasa mai yau da kuma babban wasu masu karamin kasa da karamin kasa mai yau.

Dead shorts suna da duka saboda suke haɗa da karamin kasa mai yawa a kan kabilan.

Dead Short vs Short Circuit

Don in fahimta wannan farkon dead short da short circuit, za a yi misali. Za ka duba sakamakon karamin kasa bayan biyu masu 150 V.

Idan muka saukar sakamakon karamin kasa bayan biyu masu 150 V a kan al'amuran, zai nuna 150 V. Amma, idan sakamakon karamin kasa bayan biyu yana ƙarin 150 V, ana kiran wannan a matsayin short circuit.

Yana faru ƙaramin kasa a kan short circuit, kuma akwai ƙaramin kasa mai yau a kan biyu masu.

Idan sakamakon karamin kasa yana 0 V, ana kiran wannan a matsayin dead short. Yana nufin ƙaramin kasa yana 0.

Farkon al'amuran, short-circuit, da dead-short an nuna a cikin ƙarfin da aka bani a kan karshe.

Dead Short vs Bolted Fault

Bolted fault yana nufin fault da ƙaramin kasa yana 0. Wannan ya haɗa da karamin kasa mai yawa a kan system.

Idan duk conductors suka faɗa da ground da wire mai sarrafa, ana kiran wannan a matsayin bolted fault.

Bolted fault (bolted short) yana da muhimmanci a matsayin dead short. Saboda a dead short kuma ƙaramin kasa yana 0.

Dead Short vs Ground Fault

Ground fault yana faru a kan power system idan hot wire (live wire) ya faru da earth wire ko grounded equipment frame.

A wannan halin, frame of equipment yana haɗa da sakamakon karamin kasa mai yawa. A ground fault, akwai ƙaramin kasa mai yau, kuma karamin kasa ya faru da ƙaramin kasa mai yau.

Saboda haka, ground fault yana da muhimmanci a matsayin dead short.

Misali na Dead Short

Don in fahimta dead short, za a yi misali. Za ka duba network da ke da resistors uku suka faɗa a kan series, kamar yadda aka bani a cikin ƙarfin da aka bani a kan karshe.

A al'amuran, karamin kasa yana faru da I ampere. Kuma ƙaramin kasa mai yau na kabilan yana REQ.

REQ=5+15+20
