Fashewar Shenhai-Hujja
Bisa ga ka'idodin ƙaƙƙarfan aminci a cikin ƙirar fashewar fashewa, akwai takamaiman buƙatu don kariyar casing, lantarki rufi, haɗin waya, izinin lantarki, nisan rarrafe, matsakaicin yanayin zafi, da windings a cikin kayan lantarki.
1. Kariyar Casing:
Gabaɗaya, Matsayin kariya na casing a cikin ƙarin kayan aikin lantarki na aminci kamar haka:
Ana buƙatar kariya mafi ƙarancin IP54 lokacin da kwandon ya ƙunshi ɓoyayyen sassa masu rai.
Ana buƙatar mafi ƙarancin kariya ta IP44 lokacin da kwandon ya ƙunshi ɓangarori masu rai.
Lokacin da amintattun da'irori ko tsarin ke cikin ƙara aminci kayan lantarki, ya kamata a ware waɗannan da'irori daga da'irori marasa aminci. Ya kamata a ajiye kewayon da ba tare da matakin tsaro na asali ba a cikin akwati tare da matakin kariya na akalla IP30, tare da alamun gargaɗi masu bayyana “Kada ku buɗe lokacin da kuke raye!”
2. Kayan Wutar Lantarki:
Ƙarƙashin ƙimar yanayin aiki da sharuɗɗan yin nauyi da aka halatta, matsakaicin aiki zafin jiki na ƙara aminci kayan lantarki kada ya yi mummunan tasiri ga kayan inji da lantarki na kayan rufi. Saboda haka, zafi da danshi juriya na kayan rufi ya kamata ya zama aƙalla 20K mafi girma fiye da matsakaicin zafin jiki na kayan aiki., tare da mafi ƙarancin 80 ° C.
3. Haɗin Waya:
Domin ƙara aminci kayan lantarki, Ana iya raba haɗin waya zuwa haɗin wutar lantarki na waje (inda igiyoyi na waje suka shiga cikin akwati) da haɗin wutar lantarki na ciki (haɗi tsakanin abubuwan da ke cikin akwati). Haɗin kai na waje da na ciki ya kamata su yi amfani da igiyoyi masu mahimmanci na jan ƙarfe ko wayoyi.
Don haɗin kai na waje, Kebul na waje ya kamata ya shigar da rumbun ta hanyar na'urar shigar da kebul.
Don haɗin ciki, ya kamata a shirya duk wayoyi masu haɗawa don guje wa yanayin zafi da sassa masu motsi. Dogayen wayoyi ya kamata a gyara su da kyau a wuri. Bai kamata wayoyi masu haɗin ciki su kasance suna da tsaka-tsaki ba.
Bugu da kari, Dole ne hanyoyin haɗin waya-zuwa-terminal ko bolt-to-nut sun kasance lafiyayye kuma abin dogaro.
a takaice, Ya kamata a rage juriyar lamba a wuraren sadarwar waya don guje wa zama a “yanayin haɗari” tushen kunna wuta; sako-sako da lambobin sadarwa na iya haifar da tartsatsin wutar lantarki saboda rashin kyaun sadarwa.
4. Tsabtace Wutar Lantarki da Nisan Creepage:
Wutar lantarki (mafi guntu nisa ta iska) da nisa mai rarrafe (hanya mafi guntuwa tare da saman abin rufewa) alamomi ne masu mahimmanci na aikin lantarki na ƙarin aminci na kayan lantarki. Idan ya cancanta, Ana iya ƙara haƙarƙari ko tsagi zuwa abubuwan da aka gyara don ƙara ƙyalli na lantarki da nisa mai rarrafe: hakarkarin da tsawo na 2.5mm da kauri na 1mm; tsagi tare da zurfin 2.5mm da nisa na 2.5mm.
5. Iyakance Zazzabi:
Matsakaicin zafin jiki yana nufin mafi girman zafin da aka yarda da shi na'urorin lantarki masu hana fashewa. Matsakaicin zafin jiki na ɓangarorin haɓaka kayan aikin lantarki masu aminci waɗanda zasu iya haɗuwa da su m gaurayawan iskar gas muhimmin abu ne wajen tantance aikinsu na tabbatar da fashewa. Matsakaicin zafin jiki na dumama kada ya wuce iyakataccen zafin jiki don amintaccen ƙaƙƙarfan kayan aikin lantarki mai aminci (ajin zafin jiki na kayan kariya mai fashewa), kamar yadda zai iya kunna madaidaicin cakuda gas mai fashewa.
Lokacin zayyana ƙaƙƙarfan ƙaƙƙarfan fashewar kayan wutan lantarki, baya ga yin la'akari da aikin lantarki da yanayin zafi na kayan aikin lantarki, Ya kamata a haɗa na'urorin kariyar zafin jiki da suka dace don hana wasu abubuwan haɗin gwiwa wuce iyakacin zafin jiki.
Iska:
Ƙara aminci kayan aikin lantarki kamar injina, masu aikin wuta, solenoids, da ballasts don fitulun kyalli duk sun ƙunshi iska. Ya kamata coils su sami mafi girman buƙatun rufi fiye da na yau da kullun (duba matakan ƙasa masu dacewa) kuma yakamata a sanye su da na'urorin kariya na zafin jiki don hana coils daga wuce iyaka da zafin jiki a ƙarƙashin aiki na yau da kullun ko ƙayyadaddun yanayin kuskure.. Za'a iya shigar da kariyar zafin jiki ko dai a ciki ko wajen kayan aiki kuma ya kamata ya sami daidai nau'in hana fashewa.
