Momwe Mungasankhire Chipangizo Choyenera Chotsekera Circuit Breaker
Ndikuuzeni za chochitika chomwe chinachitika mobwerezabwereza mufakitale: Asanakonze magetsi, wina ankasuntha chosinthira cha chosinthira magetsi mu kabati yogawa magetsi kupita pamalo akuti "OFF", n’kupachika chikwangwani, poganiza kuti chinali chotetezeka. Komabe, gulu loyandikana nalo, losadziwa kuti winawake anali kukonza magetsi, linabwerera n’kungoyatsanso chosinthira magetsi - zidazo zinayamba mwadzidzidzi, ndipo ogwira ntchito yokonza magetsi anatsala pang’ono kuchita ngozi.
Cholinga cha Circuit Breaker Lockout ndikusintha momwe zinthu zilili kuchokera pa "kuganiza kuti zazima" kukhala "palibe amene angaziyatse". Komabe, vuto ndilakuti ma circuit breaker amabwera m'mitundu yosiyanasiyana, ndipo zipangizo zotsekera zimasiyananso m'mitundu yosiyanasiyana. Nkhaniyi ikuthandizani kumvetsetsa bwino malingaliro anu musanagule, kuti musagule chinthu kenako n’kupeza kuti sichingaikidwe pambuyo pake.
Choyamba, onetsetsani kuti mwamvetsa chosokoneza mawaya.
Musanagule loko, onetsetsani kuti mukudziwa mtundu wa chotsekera ma circuit chomwe mukuchita nacho. Chifukwa ma circuit breaker osiyanasiyana ali ndi njira zosiyana kwambiri zotsekera.
Chotsekera chaching'ono cha ma circuit (MCB). Mtundu wofala kwambiri womwe umapezeka m'mabokosi ogawa, okhala ndi ma levers akuda m'lifupi mwa chala, okonzedwa m'mizere. Uwu ndiye mtundu wosavuta kutseka ndipo uli ndi maloko ambiri ogwirizana.
Chotsekera mafelemu (MCCB). Ndi chachikulu kuposa MCB, chokhala ndi chogwirira chachikulu komanso chokhuthala komanso mphamvu yamagetsi yapamwamba. Nthawi zambiri chimagwiritsidwa ntchito mu kabati yayikulu yogawa zinthu mu workshop kapena mu circuit yamagetsi ya chipangizo chimodzi chachikulu. Loko liyenera kufanana ndendende ndi kukula kwa chogwiriracho.
Chotsekera mafelemu (ACB). Mtundu waukulu kwambiri, womwe ndi wofunikira kwambiri m'zipinda zogawamo zinthu zamafakitale. Chogwirira chake ndi chachikulu kwambiri, ndipo zina mwa izo si zamtundu wa lever koma zamtundu wa chogwirira chozungulira. Njira yotsekera ndi yosiyana kwambiri ndi mitundu iwiri yam'mbuyomu.
Chotsekera chozungulira chogwirira. Si chosinthira chosinthira, koma chozungulira chozungulira chomwe chingagwiritsidwe ntchito ndi kiyi kapena chogwirira. Njira yotsekera ndi kutseka njira yozungulira.
Chotsekera cha makiyi chokanikiza mabatani. Zipangizo zina zakale zimagwiritsa ntchito mtundu wa batani lokanikiza. Kukanikiza pansi kumazimitsidwa, ndipo kukoka kumayatsidwa. Izi zimafuna loko yofanana ndi chivundikiro.
Lingaliro loyamba: Pitani kutsogolo kwa kabati yogawa zinthu ndikujambula zithunzi za mtundu ndi chitsanzo cha mtundu uliwonse wa chosinthira magetsi. Jambulani bwino mawonekedwe, m'lifupi mwa chogwirira, ndi malo omwe ali pafupi nacho. Kenako, onetsani zithunzizo kwa wogulitsa kuti azitha kulankhulana. Izi ndizodalirika kwambiri kuposa kufotokoza "pafupifupi m'lifupi motere" pafoni.
Mitundu ingapo yodziwika bwino ya ma circuit breaker locks
1. Mtundu wolumikizira / Mtundu wolumikizira - Mtundu wosavuta kwambiri
Mtundu uwu wa loko umamangiriridwa mwachindunji pa cholumikizira cha circuit breaker. Ikatsekedwa, pini yotsekera imayikidwa kudzera mu dzenje lotsekera kuti ikhazikike. Kukhazikitsa sikufuna zida ndipo kumatha kumalizidwa mumasekondi ochepa chabe.
Mfundo yake ndi yosavuta: Chingwecho chikagwidwa, chingwecho sichingasunthe. Chikatulutsidwa, chimakakamira, kudalira malo opanda kanthu.
Zinthu zomwe zingagwiritsidwe ntchito: Zothyola ma circuit breaker (MCBs) zokhala ndi m'lifupi mwachizolowezi, bola ngati m'lifupi mwa lever muli pafupifupi 8-12mm.
Kodi zoletsa zake ndi ziti? Pogwira ntchito ndi ma lever otakata kwambiri kapena opapatiza kwambiri, sangagwidwe bwino. Komanso, pazochitika zomwe ma circuit breaker ambiri amayikidwa moyandikana ndipo palibe malo okwanira ogwirira ntchito pafupi, ma clamp sangaikidwe.
2. Mtundu wa Snap-in / Pin-through - Wa ma circuit breakers omangidwa pa panel
Ma circuit breaker ena ali ndi dzenje laling'ono lozungulira pafupi ndi toggle lever, lomwe lapangidwira makamaka kutseka. Ikani pini yaying'ono mu dzenje ili ndikulimanga ndi loko, ndipo chogwiriracho chidzatsekedwa.
Zinthu zomwe zingagwiritsidwe ntchito: Zopukutira ma circuit breaker zopangidwa ndi pulasitiki zokhala ndi njira yotsekera yomangidwa mkati (MCCB), ndi ma MCB ena apamwamba kwambiri.
Ubwino: Ikayikidwa, imakhala yolimba kwambiri ndipo sizingagwetsedwe. Zoyipa: Ngati palibe dzenje laling'ono lotere lomwe lasungidwa pa circuit breaker panel yanu, silidzathandiza.
3. Chotsekera Chozungulira - Chabwino Kwambiri pa Ma Swichi Ozungulira
Kapangidwe ka chogwirira chozungulira ndi kosiyana ndi ka loko wa mtundu wa lever. Chogwirira cha lever sichingaikidwe konse. Chogwirira chozungulira nthawi zambiri chimakhala ndi chivundikiro kapena mphete yolumikizira, yomwe imayikidwa mozungulira chogwirira kuti isazungulire.
Kuyang'ana Kwambiri pa Kugula: M'mimba mwake ndi mawonekedwe a chogwirira. Zina ndi zozungulira, zina ndi zathyathyathya, ndipo zina zili ndi mabowo a makiyi. Kusiyana kwa kukula kwa mamilimita ochepa kudzalepheretsa kuti chigwirizane. Gwiritsani ntchito caliper poyeza; musadalire kuyerekezera kowoneka bwino.
4. Yotsekedwa / Mtundu wa bokosi - Kutseka mzere wonse
Ngati mizere ingapo ya ma circuit breaker pa kabati yogawa ikufunika kutsekedwa nthawi imodzi, kutseka imodzi ndi imodzi sikungakhale kothandiza. Loko lotsekedwa ndi chivundikiro cha pulasitiki chowonekera chomwe chimaphimba mzere wonse kapena gulu la ma circuit breaker. Chimangiriridwa ndi loko chikamangidwa bwino.
Ubwino: Imatseka chidutswa chilichonse nthawi imodzi. Zosamala: Yoyenera mabokosi ogawa zinthu komwe ma circuit breaker amakonzedwa bwino ndipo ali ndi mtunda wokhazikika. Ngati ma circuit breaker omwe ali m'bokosi logawa zinthu ali okhotakhota kapena mtunda uli wosakhazikika, chivundikirocho sichingatseke bwino.
5. Mtundu wa Universal / Koka-ndodo - Njira yomaliza
Ma circuit breaker ena ali ndi mawonekedwe achilendo kwambiri kotero kuti palibe maloko wamba omwe amalowa. Muzochitika zotere, Circuit Breaker Lockout ya "pull-rod type" kapena "universal type" ingagwiritsidwe ntchito - kwenikweni, ndi njira yosinthira loko. Mwa kumangirira zomangira kapena kukoka chingwe, switch ikhoza kutsekedwa pamalo a OFF, kenako imatha kumangidwa ndi loko.
Kunena zoona, kukhazikika kwa loko yamtunduwu sikwabwino ngati kwa akatswiri. Ingagwire ntchito, koma ngati muli ndi njira yabwino, ndi bwino kusankha yapadera. Mtundu wa chilengedwe chonse ndiye njira yomaliza osati chisankho choyamba.
