Kodi kusiyana kwa magwiridwe antchito pakati pa zowonjezera za chingwe chozizira ndi zowonjezera za chingwe chozizira ndi kotani?

1, Chisindikizo

Popeza zowonjezera zambiri za chingwe zili pamwamba pa nyumba, zobisika mwachindunji ndi malo ena, kusalowa madzi komanso kusanyowa kwakhala chimodzi mwa zinthu zofunika kwambiri kuti zitsimikizire kuti zowonjezera za chingwe ndi zotetezeka, ndipo ntchito yake yotseka ndi njira yake ziyenera kuganiziridwa.

Pakadali pano, pali njira ziwiri zotsekera:

Chimodzi ndi kutseka ndi phula kapena epoxy resin, njira yake ndi yosokonezeka, yovuta kuyilamulira, komanso siyothandiza kuteteza.

Njira ina yatsopano ndikugwiritsa ntchito sealant yolimba kwambiri, yomwe ndi yosavuta kugwiritsa ntchito, yodalirika pakugwira ntchito, komanso yosavuta kuteteza zida, zomwe zakhala zofunikira kwambiri. Kuti tigwiritse ntchito njira yatsopanoyi, choyamba tiyenera kuganizira ntchito ya sealant. Chifukwa ubwino ndi ntchito ya sealant zimakhudza mwachindunji ntchito yotseka ya cholumikizira.

Zipangizo za chingwe chamagetsi zomwe zimaphwanyika bwino ndi zowonjezera za chingwe chotanuka, kutanthauza kuti, pogwiritsa ntchito kulimba kwa rabara yamadzimadzi kapena yolimba ya silicone yokha, kukulitsa fakitale pasadakhale, kuyika pulasitiki ndi mizere yothandizira, ndikuchotsa mizere yothandizira kupita kumalo omwe asankhidwa kuti ifupikitsidwe mwachibadwa.

Luso lamtunduwu ndi njira yochepetsera kutentha kozizira, ndipo chowonjezera chamtunduwu ndi chowonjezera cha chingwe chochepetsera kutentha kozizira. Chifukwa chake, chowonjezera cha chingwe chochepetsera kutentha chozizirachi chili ndi kusinthasintha kwakukulu, komwe kungalepheretse chingwe kukula ndi kuchepa chifukwa cha malo osalinganika amlengalenga komanso ntchito yosagwirizana ya chingwe, kutanthauza malo otetezera kutentha omwe amapangidwa ndi kupuma kwa chingwe.

Vuto la zowonjezera za chingwe zomwe zimachepa kutentha ndilakuti sizisinthasintha ndipo sizingapume ndi chingwecho.

Chifukwa chake, zowonjezera za chingwe chozizira kwambiri ndi chisankho chabwino kwambiri m'malo omwe kutentha kwake kuli kosiyana kwambiri komanso momwe nyengo ndi chilengedwe zimakhudzira kwambiri!

2, Kuteteza kutentha

Zofunikira pa kutchinjiriza kwa zowonjezera za chingwe ziyenera kukwaniritsa kutchinjiriza pakati pa magawo ndi kutchinjiriza kosiyana.

Chotetezera kutentha chofanana ndi mphira wa silikoni ndi zipangizo zotetezera kutentha zomwe zimachepa. Kawirikawiri, ntchito yotetezera kutentha imadaliranso cholinga cha kutetezera kutentha cha chipangizocho, ndipo makulidwe a zinthu zophatikizidwa amakwaniritsa zofunikira.

Zipangizo za chingwe zozizira zomwe zimaphwanyika, chizindikiro cha ntchito yonse ndi 24kV/mm, ndipo makulidwe ogwirira ntchito omwe akukonzekera ayenera kukwaniritsa makulidwe a 12mm, omwe amatha kupirira mayeso a mphezi ndi overvoltage.

Zipangizo za chingwe chotenthetsera kutentha zimapangidwa ndi zinthu zosiyanasiyana zophatikizika ndipo zimakhala ndi ntchito yochepetsera kutentha pambuyo pokonza ma radiation. Chizindikiro cha insulation cha unit ndi 1.8-2.0kV/mm, ndipo makulidwe okonzedweratu ndi 3-4mm kuposa zinthu za rabara ya silicone. Insulation yofananira ndi mtunda wotetezeka kuti mphamvu isakwere kuchokera ku mphamvu yayikulu kupita ku mphamvu yochepa.

Zipangizo za rabara za silicone zomwe zimaphwanyika mu chimfine zimakhala ndi kusinthasintha kwabwino. Bola ngati kukonzekera kuli koyenera, kulimba kwake kwamphamvu kumatha kukwaniritsa mphamvu yogwira. Kaya chilengedwe chikukulirakulira kutentha kapena kuzizira, zowonjezera za chingwe zomwe zimaphwanyika mu chimfine zimaonetsetsa kuti chingwecho chakumbatiridwa mwamphamvu kuti chisapume chinyezi ndikuwonetsetsa kuti mtunda wamkati ukhale wotetezeka. Nthawi yomweyo, mwamalingaliro, mtunda wamkati wokwera wa zowonjezera zonse za chingwe zomwe zimaphwanyika mu chimfine ndi 70mm yokha, koma pazifukwa zachitetezo, mtunda wogwirira ntchito womwe ukukonzekera udakali 90mm.

Kutentha kofupikitsa kwa zowonjezera za chingwe chofupikitsa kutentha ndi 100℃-140℃. Kutentha kokha ndi komwe kumakwaniritsa zofunikira zake zofupikitsa. Kutentha kukakhala kochepa, chifukwa kuchuluka kwa kutentha kwa chingwe kumakhala kosiyana ndi kwa zinthu zomwe zimafupikitsa kutentha, malo omwe ali pansi pa 80°C amatha kusweka, kotero ming'alu idzawonekera, zomwe zimalola madzi ndi chinyezi kulowa pansi pa mphamvu ya kupuma, motero kuwononga kutchinjiriza kwa dongosolo. Ichi ndi vuto laling'ono la zinthu zomwe zimafupikitsa kutentha.

3, Malo amagetsi

Pokonza gawo lamagetsi la zowonjezera za chingwe zozizira, njira zingapo zimagwiritsidwa ntchito kusintha kufalikira kwa gawo lamagetsi pogwiritsa ntchito ma cone opsinjika, ndipo mawonekedwe ena ndi kukonza kolondola kwa R-viewpoint zimagwiritsidwa ntchito. Njirayi ndi yosavuta kuyilamulira ndikuyang'ana ndipo imatha kumalizidwa ku fakitale.

Njira yochizira magetsi pogwiritsa ntchito zowonjezera za chingwe zomwe zimachepa kutentha ndikusintha kugawa kwa magetsi pogwiritsa ntchito magawo olunjika. Ndikofunikira kudalira magawo awiri ofunikira:

Kukana kwa voliyumu, 108-11Ω.

Chokhazikika cha dielectric ndi 25.

Chifukwa cha njira yopangira zinthu zosasangalatsa komanso kusintha kwakukulu kwa zinthu zachilengedwe, zimakhala zovuta kulamulira kukhazikika kwa magawo, zomwe zingakhudze kukhazikika kwa khalidwe la chinthucho.

Chifukwa chake, zowonjezera za chingwe chozizira komanso zowonjezera za chingwe chozizira zimasiyana kwambiri munjira yokha. Kugwira ntchito pansi pa mikhalidwe yabwinobwino, zonse ziwiri zimakwaniritsa zofunikira zachitetezo. Komabe, pamene chilengedwe chikusintha, kuchepa kwa kuzizira kumakhala kopindulitsa kwambiri kuposa kuchepa kwa kutentha. Zachidziwikire, mtengo wa kuzizira ndi wokwera kwambiri kuposa wa kuzizira.
