Kwakwalwa na Kisa da Dukkantaka na Isolator
Kwakwalwa na dukkantaka na isolator yana nufin alamun cikakki da ke kusa da waɗannan isolator (gargajiya) na zafi. A lokacin da yaɗu mai sauƙi, wannan cikakki ke tafar da inganci wanda ke jagoranci sauran insulasyon. Idan an yi haka, za mu iya haifar da dukkantaka mai zurfi. A lokacin da kwakwalwar dukkantaka, darajan da za a yi don kawo shi a kan ido ba shi da kyau, kuma yana iya haifar da dukkantaka mai zurfi. Farazun dukkantaka masu kwakwalwa suna iya haifar da dabi'ar wasu abincin zafi.
Nau'o'i na Kwakwalwar Dukkantaka na Isolator
Kwakwalwa na Kayan Aiki: Wannan nau'o'in kwakwalwa na gudanar da kayan aiki, inda ake fitar da gas, ruwan, da kuma abubuwa masu tsakiyar kayan aiki. Ana iya samun wannan nau'o'in a cikin birane da kuma wurare da ake gudanar da kayan aiki, misali, karkashin kimiyar, karkashin kasuwanci, karkashin takalma, karkashin cement, karkashin kasuwa, da kuma karkashin mako da kuma ruwan.
Kwakwalwa na Tsarin Duniya: Wannan nau'o'in kwakwalwa na gudanar da tsarin duniya, inda ake samun dust, alkali, salt, ruwan mutanen duka, bird droppings, da kuma haduwar ice da snow.
Haduwar Ice da Snow: Wannan nau'o'in kwakwalwa na hasken ice da snow wata sabbin nau'o'in. Idan ice da snow suka kofin isolator, za su iya sanya ingancin surface conductivity, wanda ke iya haifar da kwakwalwar dukkantaka a lokacin da yaɗu mai sauƙi, wanda ake kira ice flash, wanda yake cikin sabbin nau'o'in na kwakwalwar dukkantaka.
Tattalin da Kula Kwakwalwar Dukkantaka na Isolator
Voltage, dukkantaka, da yaɗu mai sauƙi ne sunan uku na abubuwa da ke bukatar don kwakwalwar dukkantaka. Tattaunan da za su iya yi sun haɗa da uku, kamar increasing creepage distance, reducing surface contamination, creating dry zones on surfaces, and using new types of insulators to disrupt the formation of flashover conditions and prevent accidents.
Abokan operashin zafi sun tabbatar da tattaunan da za su iya yi don tattalin dukkantaka a wurare da dukkantaka ta cikin uku: increasing creepage distance ("climbing"), cleaning, and coating.
Adjusting Creepage Distance ("Climbing"): Daidai da creepage ratios na pollution zone maps, adjusting the external insulation creepage distance of electrical equipment in that area is called adjusting creepage distance, or "climbing". Methods include adding more insulator discs, replacing with longer creepage distance insulators, or using composite insulators.
Cleaning: A relatively simple method among anti-pollution technical measures involves removing accumulated contaminants from the insulator surface to restore its original insulation level. Cleaning can be done while energized or de-energized, with energized cleaning methods including water flushing, air blowing, and electric brushes.
Surface Treatment: Porcelain and glass insulator surfaces exhibit hydrophilic properties, making it easy for continuous water films to form under humid conditions, facilitating contamination wetting and leakage current paths. Surface treatment involves applying special coatings to insulator surfaces to enhance hydrophobicity, preventing the formation of leakage current paths during electrification.
