UKUSETSHENZISWA KWE-SF6 LOAD SWITCH IN DISTRIBUTION NETWORK

Ukusetshenziswa kwe-SF6 Load Switch ku-Distribution Network

Amaswishi asebenza ngama-voltage aphakathi asetshenziswa eziteshini ezijwayelekile ze-hub wonke asebenzisa ama-circuit breaker njengamadivayisi okulawula nokuvikela, futhi kumele abe nokuvala okuzenzakalelayo. Kodwa-ke, amandla okunikezwa kwamandla esiteshini ngasinye sokusabalalisa amandla kunethiwekhi yendandatho ngokuvamile awakhulu, ugesi wawo olinganiselwe mncane kunogesi olinganiselwe wenethiwekhi yendandatho, futhi ukuvala akudingeki, ngakho-ke iyunithi yokunikezwa kwamandla yesiteshi sokusabalalisa amandla senethiwekhi yendandatho ingasebenzisa isakhiwo esilula, intengo ephansi kanye nokusebenza okuphezulu. Inhlanganisela yeswishi yomthwalo + i-fuse engahlangabezana nezidingo.

Ukuhlanganiswa kweswishi yomthwalo kanye nefusi ukuze kuthathe indawo ye-circuit breaker yendabuko kuye kwasetshenziswa kwamanye amazwe iminyaka engamashumi amahlanu. Isilinganiso sokukhishwa kwama-circuit breaker singu-1:2.5, okusesemuva kakhulu kwamazwe athuthukile ezimboni. Kubonisa nokuthi ezweni lakithi, ama-SF6 load switch anamathuba amakhulu ekuthuthukisweni kwamanethiwekhi okusabalalisa ama-voltage aphakathi.

Ngamafuphi, ngokuqhathanisa ukusetshenziswa kwamaswishi omthwalo we-SF6 kanye nama-circuit breaker kumanethiwekhi okusabalalisa amancane, amaphuzu alandelayo angafingqwa:

I-circuit breaker ibambisana nokuvikelwa kwe-relay futhi inazo zonke

Umsebenzi wokuvikela kanye nomsebenzi wokusebenza.

Iswishi yomthwalo ye-SF6 ngokuyisisekelo inomsebenzi ofanayo ne-circuit breaker, ngaphandle kokuthi ayikwazi ukuphula i-short circuit (ayidingeki).

Ukusebenza kwe-SF6 load switch ephula i-transformer engenamthwalo kungcono kunokwe-circuit breaker.

Iswishi yomthwalo ye-SF6 + i-fuse ekhawulela amandla kagesi nayo ingaphula i-short circuit ngesikhathi esisodwa, okucishe kufane ne-circuit breaker.

Iswishi yomthwalo ye-SF6 + i-fuse ekhawulela amandla kagesi ayimbi kakhulu kune-circuit breaker, kodwa izindleko ziphansi kakhulu.
