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 isebenzisa umngxuma owakhiwe ngezinto eziqinile ezikhiqiza igesi ukuze ikhiqize inani elikhulu legesi ngaphansi kwesenzo se-arc ukuze yakhe 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, futhi iswishi ene-pole eyodwa isishiswe izikhathi eziningi. Ukuqhekeka kwe-carbonized kwe-epoxy resin insulators.

②Uma iswishi ivuliwe, iswishi yomthwalo ekhiqiza igesi ngezinye izikhathi izokhipha ukuvuza kokukhanya kwe-arc, okuthinta ukuphepha komuntu siqu. Ngokwesingeniso somenzi, inqubo yokucisha i-arc yomklamo weswishi ibheka kakhulu umthwalo ongaphansi komthwalo obukhoma. Uma oxhumana nabo abayinhloko nabasizayo bengavumelanisiwe, kulula ukuthi i-Arc ivuleke.

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.
