Principle of Work and Mechanism of Arc Suppression of Magnetic Blowout Device in DC Circuit Breakers

Sistem kisan gurbin da ciyawa mai karfi shi ne na kan amfani da cikin abincin jirgin hanyar DC, saboda gurbin da yake faru a lokacin da aka kawo abin da ya yi yana iya haɗa waɗanda suka taka da kai da suka gina ƙarfin dabbobi.

A cikin sassan AC, abin da yake faru yana zama zero biyu a baya wanda aka saka, kuma abincin jirgin hanyar AC suna amfani da wannan bangaren bayan zero don kisan gurbin.

Amma a cikin sassan DC, babu abin da yake faru zero ta hanyar tsakiyar, wanda yana ƙara mafi ƙananan don kisan gurbin a cikin abincin jirgin hanyar DC. Saboda haka, abincin jirgin hanyar DC sun buƙaci ƙarin samun coil zaɓe ko kisan gurbin da ake samu da samar da magana mai zurfi don kusan gurbin da aka faru zuwa ciyawa mai kisan gurbin, inda an kaɗe gurbin, kaɗe gurbin, kuma zama ladan gurbin, wanda ke ƙara fitowa da kisan gurbin da ƙara.

Yanzu, ciyawa mai kisan gurbin a cikin abincin jirgin hanyar DC suna da duwatsu muhimman kompoonenti: coil zaɓe (electromagnet) da kontrola.Kontrola shine muhimmiyar da take ƙunshi shiga abin da yake faru, kuma a lokacin da abin ya haɗa takarda na amfani da ita, tana bayar sharhi masu shiga don buga electromagnet coil.

Coil zaɓe (electromagnet) yana ƙunshi ƙwarewa mekaniki mai yuka (Ampere force) daidai da abin da kontrola ta bayar, tare da kisan gurbin zuwa ciyawa mai kisan gurbin.

Daga baya, za mu iya nuna yadda ake iya tabbatar da inganci yaƙe N da S poles na coil zaɓe (electromagnets) a cikin abincin jirgin hanyar DC mai girma da karamin abin da suka faru, a lokacin da amfani da ƙarin sauƙi ko sauran ƙungiyoyi, don haka za a iya ƙara ƙwarewa mai yuka don kisan gurbin zuwa ciyawa mai kisan gurbin don kisan gurbin da ba da ƙula.

I. Abin Da Ya Faru Mai Girma

Yadda ake iya tabbatar da inganci yaƙe N da S poles: magnet na hagu ya kasa yana da N-pole, kuma na hagu ya tsohu yana da S-pole.

Kamar yadda aka nuna a cikin hoton: idan ake amfani da rukuni mai yau, saboda yawan abin (I) da yawan Ampere force (F) wanda yake faru (mai yuka), za a iya ƙunshi yawan magnetic flux density (B)—wanda yake faru daga N-pole. Saboda haka, magnet na hagu ya kasa na abin da ya faru mai girma yana da N-pole, kuma na hagu ya tsohu yana da S-pole.

Bayar volt-level millivolt a cikin shunt don buga magnetic blowout device. Kuma karkashin magnet mai amfani (da yaɗuwar pole) zuwa magnets a cikin abin da ya faru mai girma. Idan ake amfani da yanayin da like poles repel da opposite poles attract, tabbatar da inganci yaƙe poles.

II. Abin Da Ya Faru Mai Tsohu

Yadda ake iya tabbatar da inganci yaƙe N da S poles: magnet na hagu ya kasa yana da S-pole, kuma na hagu ya tsohu yana da N-pole.

Kamar yadda aka nuna a cikin hoton: idan ake amfani da rukuni mai yau, saboda yawan abin (I) da yawan Ampere force (F) wanda yake faru (mai yuka), za a iya ƙunshi yawan magnetic flux density (B)—wanda yake faru daga N-pole. Saboda haka, a cikin abin da ya faru mai tsohu, magnet na hagu ya kasa yana da S-pole, kuma na hagu ya tsohu yana da N-pole.

Bayar volt-level millivolt a cikin shunt don buga magnetic blowout device. Kuma karkashin magnet mai amfani zuwa magnet a cikin abin da ya faru mai tsohu. Idan ake amfani da yanayin da like poles repel da opposite poles attract, tabbatar da inganci yaƙe polarity.

A lokacin da ƙarin sauƙi, yana da kyau wajen ƙunshi masu amfani da rukuni mai yau: saboda yawan abin da yawan Ampere force (F), ƙunshi yawan magnetic flux density (B), don tabbatar da inganci yaƙe N da S poles na electromagnet, don kisan gurbin da ba da ƙula.
