Kusiyana pakati pa switch break load ndi circuit breaker

Akatundu yopumaswitch ndi chida chamagetsi pakati pa ahigh-voltage circuit breakerndi ahigh-voltage kudzipatula switch . M'nkhaniyi, tiyeni tione mfundo ntchito ya katundu yopuma lophimba ndi kusiyana lophimba katundu yopuma ndi dera wosweka.

Mfundo yogwira ntchito yosinthira katundu

High-voltageload break switch imagwira ntchito mofanana ndi wodutsa dera. Nthawi zambiri, kuyika kwa chipangizo chozimitsa cha arc chosavuta, koma mawonekedwe ake ndi osavuta. Chithunzichi chikuwonetsa kusintha kwa mpweya wopanikizika kwambiri. Njira yake yogwirira ntchito ndi: pamene brake imatsegulidwa, pansi pa kasupe wotsegulira, spindle imazungulira mozungulira. Kumbali imodzi, pisitoni imayenda m'mwamba kudzera m'makina olowera kuti iphanikiza mpweya; Kumbali imodzi, kudzera mu njira yopatsirana yomwe ili ndi magawo awiri a makina olumikizira anayi, mpeni waukulu umatsegulidwa koyamba, ndiyeno wosweka arc amakankhidwa kuti atsegule kukhudzana kwa arc breaker, ndipo mpweya woponderezedwa mu silinda umawomberedwa. kudzera mumphuno kuti mutulutse arc.

Potseka, chodulira chachikulu ndi arc breaker amatembenukira mozungulira nthawi yomweyo kudzera pa spindle ndi njira yopatsira, ndipo cholumikizira cha arc chimatsekedwa poyamba. Spindle imapitilirabe kuzungulira kotero kuti cholumikizira chachikulu chitseke pambuyo pake. Panthawi yotseka, kasupe wotsegulira nthawi imodzi amasunga mphamvu. Chifukwa chosinthira katundu sichingathyole mayendedwe amfupi, nthawi zambiri amagwiritsidwa ntchito ndi fuse yomwe imachepetsa mphamvu yamagetsi. Ntchito yochepetsera yaposachedwa ya fuse yochepetsera sikungomaliza ntchito yophwanya dera, komanso imachepetsa kwambiri mphamvu yamafuta ndi magetsi obwera chifukwa chaposachedwa.

Chifukwa chake, switch break break ndiye chida chosinthira pakati pa chophwanya dera ndi chosinthira chodzipatula. Ili ndi chipangizo chozimitsa cha arc chosavuta, chomwe chimatha kudula zomwe zidalipo kale komanso zochulukira, koma sizingadutse nthawi yayitali.

Kusiyana pakati pa ma switch break load ndi ma circuit breakers

Kuchokera pamalingaliro achikhalidwe, zosinthira zonyamula katundu ndizosiyana kwambiri ndi zowononga madera. Kusinthana kwa katundu kumagwiritsidwa ntchito makamaka kuswa ndi kutseka katundu panopa. Itha kugwiritsidwa ntchito ndi ma fuse okwera kwambiri kuti alowe m'malo oyendetsa magetsi okwera mtengo ndikudula mphamvu yamagetsi, ndiye kuti, yanthawi yayitali. Zimatsimikiziridwa kuti ntchito yozimitsa ya arc yosinthira katundu ndi yofooka, zomwe zimachepetsa mtengo wopanga. Ndi ndendende chifukwa chosinthira chachikhalidwe chosiyanitsa sichimagwiritsidwa ntchito kuti muchepetse kusiyana pakati pa fuse yolakwika ndi wophwanya dera, palibe chifukwa cholumikizira chipangizo choteteza ndi chida chodziwikiratu, chifukwa chake chosinthiracho chimakhala pamanja. opareshoni. Sizingagwiritsidwe ntchito ndi magetsi. Pamapangidwe a ophwanya dera, amaganiziridwa kuti sizomwe zimatha kutsegulidwa ndikuzimitsidwa.

Masinthidwe opangidwa mwapadera kuti azitha kuwongolera pakali pano (zolakwika zapano, zovoteledwa pakali pano) ndi zowononga madera, ndipo mulingo wa zotchingira zopumira ndi otsika kwambiri, kotero kuthekera kogwiritsa ntchito mopitilira muyeso ndikofooka kwambiri. Chosinthira chomwe chimapangidwa kuti chigwirizane ndi voteji (mulingo wa kutchinjiriza wa fracture ndi wokwera kwambiri, womwe ungathe kuthana ndi voltage yapamwamba yolimbana ndi mtengo) ndiyosinthiratu, yomwe imadziwika kuti chida brake. Katundu yopuma lophimba ndi lophimba pakati pa awiri amene angathe kupirira panopa (oveteredwa panopa) ndi voteji (kutchinjiriza mlingo yopuma ndi apamwamba kuposa wosweka dera, koma m'munsi kuposa kudzipatula lophimba), koma ngakhale katundu yopuma lophimba akhoza kusweka ndi kutseka oveteredwa panopa, kutseka yochepa dera panopa, koma mosamalitsa ndi zoletsedwa kuswa yochepa dera panopa.

Iyi ndiye mfundo yogwirira ntchito yosinthira katundu komanso kusiyana pakati pa switch break break ndi circuit breaker.
