Izesekeli Zentambo Yamandla Ephezulu Yokuxhunywa Kwekhebula Ngaphansi Komhlaba

Ukuxhumeka kwekhebula elingaphansiukwakha umgogodla wengqalasizinda yethu kagesi.Asetshenziselwa ukuxhuma ama-transformer, amabhokisi amagatsha, amajeneretha kanye neminye imithwalo kagesi.Enye yezingxenye eziyisisekelo zakho konke ukuxhumana kwe-loadbreak yi-isixhumi sendololwanekanye ne-bushing insert.Ahlolwe ngokugcwele futhi afakwe amatheminali epulaki afakwe ngaphakathi ukuze axhume izintambo ezingaphansi komhlaba ezinhlelweni zokusabalalisa amandla.Kule bhulogi sixoxa ngezesekeli zezintambo zamandla eziphezulu zokuxhuma izintambo ezingaphansi komhlaba kuma-transformer noma amabhokisi amagatsha amandla.

Izinyathelo zokuphepha zokusetshenziswa

Lapho uphatha ukuxhunywa kukagesi, kufanele kuthathwe izinyathelo zokuphepha ezifanele.Njalo qinisekisa ukuthi ugesi uvaliwe ngaphambi kokuxhuma.Qiniseka ukuthi usebenzisa insiza yentambo yamandla elinganiselwe ngokufanele ukuze isekele i-voltage edingekayo nomthwalo.Hlola izixhumi nezinto ezifakwa ehlathini ukuze uthole noma yiziphi izimpawu zokulimala ngaphambi kokuzisebenzisa.Uma uthola noma yimiphi imifantu noma amazinyo, ungazixhumi bese ufaka okusha.

Indawo yomkhiqizo

Izixhumi zendololwaneikakhulukazi asetshenziselwa ukuxhuma izintambo ezingaphansi komhlaba kuma-pad transformers wezinhlelo zokusabalalisa amandla, amabhokisi egatsha atholakala kugesi aseduze, namabhokisi amagatsha ekhebula ahlonyiswe nge-load break bushings.Izixhumi zenzelwe ukumelana nezimo ezinzima zemvelo ezinjengomswakama, ukungcola namakhemikhali.Zenziwe ngezinto ezisezingeni eliphezulu ezimelana nokugqwala, ukuhuzuka kanye nemisebe ye-UV.Zonke izinsiza zezintambo zikagesi ezisetshenziselwa ukuxhuma izintambo ezingaphansi komhlaba kufanele zihambisane nezindinganiso zokuphepha futhi zigunyazwe yinhlangano egunyaziwe.

Isixhumi sokulayisha i-voltage ephezulu

Uma kwenzeka i-voltage yomthwalo idlula izinga elithile, kusetshenziswa izixhumi ezikhethekile ze-insulated.Lezi zixhumi zenzelwe ukuphatha ama-voltage aphezulu futhi zivimbele i-arcing.I-arc iwukuphuka komoya kagesi phakathi kwamakhondaktha amabili aphilayo.Idalwa lapho umehluko we-voltage uphakeme ngokwanele futhi izakhiwo zokuvikela umoya zibhujiswa.Izixhumi ezikhethekile ze-insulated zenzelwe ukuvimbela lokhu, zizenze zifanele ukulayishwa kwamandla kagesi aphezulu.

Izesekeli zokugawula

Ukubeka phansi kuyisici esibalulekile sokuphepha kukagesi.Uma kwenzeka ugesi ungasebenzi, kungase kubangele ukulimala kwempahla, impahla kanye nabasebenzi.I-Grounding inikeza indlela ephephile yokuphambukisa ukukhishwa emhlabeni.Zonke izesekeli zentambo yamandla kufanele zisekelwe kahle.Izixhumi zokubeka phansi zisetshenziselwa ukusungula ukuxhumana phakathi kwemishini kagesi nomhlaba.Zixhunywe ocingweni oluphansi, olunesibopho sokuphambukisa ukukhishwa emhlabeni.

Ekuphetheni

Izesekeli zezintambo zikagesi ziyingxenye ebalulekile yengqalasizinda yakho kagesi.Badlala indima ebalulekile ekuxhumeni izintambo ezingaphansi komhlaba kuma-transformer, amajeneretha namabhokisi kagesi.Kubalulekile ukusebenzisa izesekeli zezintambo zamandla ezifanele eziklanyelwe ukuhlangabezana nomthwalo kagesi, ugesi kanye nezimo zemvelo.Njalo thatha izinyathelo zokuphepha lapho usebenza ngokuxhunywa kukagesi ngoba kungaba yingozi.Ngokulandela lezi ziqondiso, ungaqinisekisa ukuphepha nokuthembeka kwesistimu yakho kagesi.
