Maswichi Opangidwa ndi Molded Case: Kuonetsetsa Chitetezo Chodalirika cha Magetsi ndi Kulamulira M'malo Ogulitsa Mafakitale

Masiwichi a Mlanduwu Wopangidwa: Buku Lotsogolera Lonse

Maswichi opangidwa ndi chivundikiro ndi zinthu zofunika kwambiri m'makina amagetsi, zomwe zimapereka chitetezo ndi kuwongolera ntchito zosiyanasiyana. Maswichi awa adapangidwa kuti azitha kuthana ndi mphamvu zamagetsi ndi magetsi ambiri, zomwe zimapangitsa kuti akhale oyenera mafakitale, malonda ndi nyumba. M'nkhaniyi, tifufuza makhalidwe, ntchito, ndi ubwino wa maswichi opangidwa ndi chivundikiro, komanso kufunika kwawo pachitetezo ndi chitetezo chamagetsi.

Makhalidwe a masiwichi a pulasitiki

Chosinthira cha pulasitiki chili ndi kapangidwe kolimba komanso magwiridwe antchito odalirika. Nthawi zambiri chimakhala m'nyumba yolimba ya pulasitiki kapena yopangidwa ndi thermoset yomwe imapereka chitetezo ku zinthu zamkati. Zosinthirazi zimapezeka m'mitundu yosiyanasiyana yamagetsi, kuyambira ma amps mazana angapo mpaka ma amps zikwi zingapo, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pamagetsi osiyanasiyana.

Chimodzi mwa zinthu zazikulu zomwe zimagwiritsidwa ntchito ndi ma switch apulasitiki ndi kuthekera kwawo kupereka chitetezo cha ma short circuit ndi overload. Ali ndi ma trip unit omwe amatha kuzindikira ndikuyankha mavuto amagetsi osazolowereka, monga overcurrent ndi ma short circuit, mwa kusokoneza mwachangu kuyenda kwa magetsi. Izi zimathandiza kupewa kuwonongeka kwa makina amagetsi ndi zida zake ndikuwonetsetsa kuti ogwira ntchito ali otetezeka.

Kugwiritsa ntchito chosinthira cha pulasitiki

Maswichi opangidwa ndi chivundikiro amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo kugawa mphamvu, kulamulira mota ndi kuteteza ma circuit. M'mafakitale, amagwiritsidwa ntchito kwambiri m'ma switchboard, ma switchboard, ndi malo owongolera mota kuti apereke kugawa mphamvu kodalirika komanso kogwira mtima. M'nyumba zamalonda ndi m'nyumba zogona, maswichi opangidwa ndi chivundikiro amagwiritsidwa ntchito kuteteza ma circuit ndi zida ku zinthu zodzaza ndi magetsi komanso ma short circuit.

Ma switch amenewa amagwiritsidwanso ntchito kwambiri m'makina ogwiritsira ntchito mphamvu zongowonjezwdwanso monga kukhazikitsa mphamvu ya dzuwa ndi mphepo, zomwe zimathandiza kwambiri kuonetsetsa kuti zomangamanga zamagetsi zikugwira ntchito bwino komanso modalirika. Kuphatikiza apo, ma switch opangidwa ndi zikwama amagwiritsidwa ntchito m'malo osungira deta, m'zipatala ndi m'malo ena ofunikira komwe magetsi osasokoneza komanso chitetezo chamagetsi ndizofunikira kwambiri.

Ubwino wa ma switch a pulasitiki

Maswichi opangidwa ndi chivundikiro amapereka zabwino zingapo, kuphatikizapo kugwira ntchito bwino, kudalirika komanso kusavuta kuyika. Kapangidwe kawo kolimba komanso zida zapamwamba zoyendera zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito molimbika, zomwe zimateteza bwino ku zovuta zamagetsi. Kuphatikiza apo, maswichi awa adapangidwa kuti azisavuta kuyika ndi kukonza, kuchepetsa nthawi yogwira ntchito komanso kuonetsetsa kuti makina amagetsi akuyenda bwino.

Ubwino wina waukulu wa ma switch opangidwa ndi chikwama ndi kuthekera kogwiritsa ntchito zida zosiyanasiyana ndi zida zothandizira, monga kumasula ma shunt, kumasula ma undervoltage ndi ma contact othandizira. Kusinthasintha kumeneku kumalola makonzedwe apadera kuti akwaniritse zofunikira zinazake zogwiritsira ntchito, zomwe zimapangitsa kuti switchyo ikhale yosinthasintha komanso yogwira ntchito.

Kufunika kwa maswichi apulasitiki pa chitetezo chamagetsi

Maswichi opangidwa ndi chivundikiro amagwira ntchito yofunika kwambiri pakuonetsetsa kuti magetsi ali otetezeka komanso otetezeka. Mwa kuzindikira mwachangu ndikuyankha mavuto amagetsi monga kuchuluka kwa magetsi ndi ma circuit afupiafupi, maswichi awa amathandiza kupewa moto wamagetsi, kuwonongeka kwa zida, ndi kuvulala kwa anthu. Amateteza makina amagetsi ndi omwe akugwira ntchito pafupi mwa kusokoneza kayendedwe ka magetsi mwanjira yowongoka, motero amachepetsa mphamvu yamagetsi yomwe ingachitike chifukwa cha kulephera kwa magetsi.

Mwachidule, maswichi a ma case opangidwa ndi molded ndi gawo lofunika kwambiri mu makina amagetsi, zomwe zimapereka chitetezo chodalirika komanso kuwongolera ntchito zosiyanasiyana. Kapangidwe kake kolimba, mawonekedwe ake apamwamba komanso kusinthasintha kwake zimapangitsa kuti ikhale gawo lofunikira kwambiri pa zomangamanga zamagetsi zamakono, zomwe zimathandiza kukonza chitetezo, magwiridwe antchito komanso kudalirika kwa ma installation amagetsi. Kaya m'mafakitale, mabizinesi kapena nyumba, maswichi a ma case opangidwa ndi molded amachita gawo lofunikira pakuwonetsetsa kuti makina amagetsi akuyenda bwino komanso motetezeka.
