Kodi ntchito ya vacuum circuit breaker ndi yotani?

Pamene avacuum circuit breakerili pamalo otsekedwa, kutchinjiriza kwake padziko lapansi kumapangidwa ndi ma insulators oyenera.Pakachitika cholakwika chokhazikika panjira yolumikizidwa ndi chowotcha dera la vacuum, ndipo malo olakwika apansi samachotsedwa pambuyo paulendo woyendetsa dera, kusiyana kwa mpweya pakupuma kwa wophwanya dera kuyeneranso kukhala ndi udindo pakutsekereza kwa nthaka. basi yamagetsi.Kusiyana kwa kutchinjiriza kwa vacuum pakati pa olumikizana kuyenera kupirira ma voltages osiyanasiyana okonza popanda kuwonongeka.Chifukwa chake, mawonekedwe otsekera apakati a vacuum asanduka kafukufuku wapano kuti apititse patsogolo mphamvu yamagetsi yachipinda chozimira cha arc, ndikupanga chopukutira chopumira chimodzi chokhacho chikhale chokwera kwambiri.Zosokoneza madera ndi: 1. Mtunda wotsegulira wolumikizana ndi wawung'ono.Mtunda wotsegulira wolumikizana ndi 10KV vacuum circuit breaker ndi 10mm yokha.Makina ogwiritsira ntchito ali ndi mphamvu yaing'ono yokwera ndi pansi, kugunda kochepa kwa gawo lamakina, komanso moyo wautali wamakina.2. Nthawi yoyaka moto ya arc ndi yaifupi, mosasamala kanthu za kukula kwa makina osinthira, nthawi zambiri ndi theka la kuzungulira.3. Chifukwa cha kavalidwe kakang'ono ka kavalidwe ka kufalitsa ndi kuyendetsa pamene akuphwanya panopa, moyo wamagetsi wa ogwirizanitsa ndi wautali, voliyumu yonseyo imasweka nthawi 30-50, mphamvu yowonongeka imasweka nthawi zoposa 5000, phokoso ndilochepa. , ndipo ndi yoyenera kugwira ntchito pafupipafupi.4. Pambuyo pa arc kuzimitsidwa, liwiro lokonzekera la zida zolumikizirana limakhala lachangu, ndipo mawonekedwe olakwika a dera lapafupi la kusweka amakhala bwino.5. Yaing'ono ndi yopepuka kukula, yoyenera kuswa capacitive katundu panopa.Chifukwa cha ubwino wake wambiri, amagwiritsidwa ntchito kwambiri m'malo ogawa.Zitsanzo zamakono ndi: ZN12-10, ZN28A-10, ZN65A-12, ZN12A-12, VS1, ZN30, ndi zina zotero. Momwe ma vacuum circuit breakers amagwirira ntchito "Vacuum circuit breaker" ndi yotchuka chifukwa cha arc kuzimitsa sing'anga ndi insulating medium of the kulumikizana kwapakati pambuyo kuzimitsa kwa arc.Zili ndi ubwino wa kukula kochepa, kulemera kwa thupi, kulemera kwa thupi, etc. Ndikoyenera kugwira ntchito pafupipafupi.Chifukwa chake, imagwiritsidwa ntchito kwambiri pakugawa maukonde.Mfundo yogwirira ntchito ya vacuum circuit breakers si yovuta: 1. Kuwonongeka kwa ma cathode: Pansi pa mphamvu yamagetsi yamphamvu, kutentha kwa ma protrusions pamtunda woipa wa electrode kumawonjezeka chifukwa cha kutentha kwa Joule kwa mphamvu yamagetsi, komanso pamene Kutentha kumafika povuta kwambiri, ma protrusions amasungunuka kuti apange nthunzi, zomwe zimapangitsa kuti zitheke.2. Kuwonongeka kwa anode: Kuphulika kwa anode kumatenthetsa mfundo chifukwa cha mtengo wa ion wotumizidwa ndi anode, kutulutsa kusungunuka ndi nthunzi, ndipo kuwonongeka kwa mpata kumachitika.Mikhalidwe yakusokonekera kwa anode imakhudzana ndi kuchuluka kwa magetsi kumunda ndi kugwa komanso kusiyana kwapakati.Kuphatikiza apo, kukana kwa dera la vacuum circuit breaker ndiye pyrogen yayikulu yomwe imakhudza kutentha, ndipo kukana kwachipinda chozimitsa cha arc nthawi zambiri kumakhala kopitilira 50% ya kukana kwa dera la chotchinga chamagetsi.Kulimbana ndi kukana kwa dera lolumikizana ndi gawo lalikulu la kukana kwa dera la vacuum interrupter.Popeza kuti njira yolumikizirana imasindikizidwa mu chosokoneza cha vacuum, kutentha komwe kumapangidwa kumatha kutayidwa kunja ndi ndodo zoyendetsa komanso zokhazikika.Mfundo yowonongeka ya mipata ya vacuum iyi imasonyeza kuti zinthu za siteji ya vacuum ndi pamwamba pa siteji ndizo zinthu zazikuluzikulu za kutsekemera kwa kusiyana kwa vacuum.
