ISISHINTSHI SOKULAYISHA IKHOLAMU ESIYI-10KV

Iswishi yokulayisha kukholomu inamandla okuthwala nokuphula ugesi olinganiselwe, kodwa ayikwazi ukuphula ugesi we-short-circuit. Isetshenziswa kakhulu ekuhlukaniseni umugqa kanye nokuhlukaniswa kwamaphutha.

(1) Iswishi yomthwalo ekhiqiza igesi. Iswishi yomthwalo ekhiqiza igesi iwukusebenzisa umngxuma owakhiwe ngezinto eziqinile ezikhiqiza igesi ukukhiqiza inani elikhulu legesi ngaphansi kwesenzo se-arc ukwakha i-arc evuthela igesi. Ngenxa yesakhiwo sayo esilula kanye nezindleko eziphansi, yake yasetshenziswa kabanzi.

(2) I-Vacuum, i-SF6 load switch. Ngokubukeka kanye namapharamitha afana nama-vacuum kanye nama-circuit breaker e-SF6, umehluko ukuthi i-load switch ayinayo i-CT yokuvikela futhi ayikwazi ukuphula i-short-circuit current, kodwa ingamelana ne-short-circuit current futhi ivale i-short-circuit current, enempilo ende, izici ezingenayo i-maintenance, impilo ye-mechanical, i-rated current current evulekile Inani lokuphazamiseka lingaphezu kwezikhathi eziyi-10,000, elifanele ukusebenza njalo.

(3) Amathiphu okusebenzisa:

①Ngokombono wokusetshenziswa, izinga lokuhluleka kweswishi yomthwalo ekhiqiza igesi liphezulu kakhulu, isembozo sokucisha i-arc siwile, kanti iswishi ene-pole eyodwa ishiswe kaningi. Ukuqhekeka kwe-carbonized kwe-epoxy resin insulators.

②Iswishi yomthwalo ekhiqiza igesi ngezinye izikhathi izokhipha ukuvuza kokukhanya kwe-arc lapho ugesi uvaliwe, okuzothinta ukuphepha komuntu siqu. Ngokwesingeniso somenzi, inqubo yokucisha i-arc yomklamo weswishi ibheka kakhulu umthwalo ongaphansi ophilayo. Lapho oxhumana nabo abayinhloko nabasizayo bengavumelaniswanga lapho iswishi ivaliwe, kulula ukuthi i-Arc ivuleke ngokukhanya.

③Isembozo sokucisha i-arc seswishi yomthwalo ekhiqiza igesi sidinga ukugcinwa ngokungajwayelekile. Sidinga ukuhlolwa nokugcinwa cishe izikhathi ezingu-20 zokuphula umthwalo ogcwele. Asisihle njengeswishi yohlobo lwe-vacuum kanye ne-SF6, engaphulwa izikhathi ezingaphezu kuka-10,000, futhi umthwalo wokusebenza nokulungisa wesikhathi eside mkhulu.

④Indlela yokusebenza yeswishi yomthwalo ekhiqiza igesi ingahlukaniswa ibe uhlobo lwe-hook kanye nohlobo lwe-pull-down operation lever. Uhlobo lwe-pull-down operation lever kufanele lukhiywe lapho kufakwa isibambo sokusebenza, futhi umzimba wokukhiya udinga ukushintshwa nokugcinwa njalo, okuyinto enzima ukuyisebenzisa. Induku yokusebenza kufanele ifakwe ngaphezu kuka-2.5M ngaphezu komhlaba, ngaphandle kwalokho izolimala kalula ngamandla angaphandle.

⑤Intengo yamanje yeswishi yokuhlanganisa umthwalo we-vacuum ifana neyeswishi ekhiqiza igesi, futhi ukuthembeka kwayo nokuphepha kwayo akunakuqhathaniswa neswishi ekhiqiza umthwalo wegesi, ngakho-ke kufanele isetshenziswe kangcono lapho ukhetha.
