Kuran fanga faratiw
High-Voltage Breakdown: PTFE kasɛtiw ka dielektriki tiɲɛni kunbɛncogo dan ye. Misali la, kaseti min janya bɛɛ ye milimɛtɛrɛ 0,11 ye, o bɛ se ka kɛ ni tiɲɛni hakɛ ye 6,1kV ɲɔgɔn ye. Ni a janya tɛ se ka kɛ walima ni kɔnɔna nɔgɔw (pinɛw, nɔgɔw) bɛ se ka kɛ sababu ye ka tension caman tiɲɛ nɔgɔya la ani ka insulasi tiɲɛ.
Yɔrɔ dɔw bɔli (Corona Discharge): Lamini minnu na tension ka bon, dugukolo nɔgɔw (buguri, tulu nɔgɔw) ani kɔnɔna fiɲɛbɔyɔrɔ misɛnninw bɛ kuran foro sɛnɛyɔrɔw kɛ, o bɛ corona bɔli daminɛ. Ni ji bɔli bɛ to sen na waati jan kɔnɔ, o bɛ insulating layer tiɲɛ dɔɔni dɔɔni, o bɛ na ni a dɛsɛ ye joona.
Insulasi tiɲɛni ka bɔ sigida fɛnw na:
Nɛnɛ : Ni nɛnɛ hakɛ tɛmɛna 85% kan, PTFE sanfɛla rezisti bɛ se ka jigin kosɛbɛ – ka bɔ 10⊃1;7Ω la ka se 10⊃1;⊃2;Ω lamini na – ani tiɲɛni wulicogo bɛ se ka dɔgɔya ni 30% ye ka se 50% ma.
Nɔgɔw : Bugun walima kɔgɔ fiyɛli kaseti sanfɛla la, o bɛ kɛ sababu ye ka bɔrɔw dilan minnu bɛ taa ni fɛnw ye, ka jibɔ siraw dilan.
Kuranko minɛnw na, PTFE kasɛtiw ka dielektriki fanga tɛ nafa latigɛlen ye nka a bɛ bɔ baarakɛcogo cogoyaw de la kosɛbɛ. Ni korona bɛ se ka kɛlɛ, a dilannikɛlaw ka teli ka fasa fɛnɲɛnamaw don i n’a fɔ mika walima seramiki fɛnɲɛnamafagalanw PTFE matirili kɔnɔ.

Ni aw bɛ PTFE kasɛti sugandi invertɛri motɛriw kama minnu bɛ se ka wuli kosɛbɛ (misali la, 6kV fo 10kV kalasi), a ka ɲi aw ka baara kɛ ni PTFE kaseti ye min bɛ se ka korona kɛlɛ, a janya bɛ se milimɛtɛrɛ 0,18 ma a dɔgɔyalenba la ani ka tension partial discharge inception (PDIV) sɛgɛsɛgɛ baarakɛcogo funteni yɛrɛ la, barisa a ka c’a la, PDIV bɛ dɔgɔya ni 20-30% ye 150°C la ni a bɛ tali kɛ so funteni na.
Farati minnu bɛ sɔrɔ funteni sabatili la
Kɔrɔya min bɛ kɛ ni funteni caman ye: A ka c’a la, PTFE kasɛtiw bɛ se ka baara kɛ ka ɲɛ ni funteni bɛ to ka kɛ 260°C ye. Nka ni funteni tɛmɛna 250°C kan (kɛrɛnkɛrɛnnenya la 300°C kɛrɛfɛ), molekiyɔmu cakɛdaw bɛ daminɛ ka toli. O tiɲɛni bɛ dɔ bɔ kosɛbɛ dielektriki fanga la ani ka faratiw lase insulasi tiɲɛni ma.
Thermal-Oxygen Synergistic Effect: Funteni caman ni oksizɛni faralen ɲɔgɔn kan, o bɛ fɛnw kɔrɔya teliya. Ni funteni ni nɛnɛ bɛ yen, tiɲɛni min bɛ sɔrɔ tension resistance baarakɛcogo la, o bɛ se ka bonya ni 30% fo 50% ye ni i y’a suma ni funteni jalen dɔrɔn ye.
Ni PTFE kase bɛ kɛ switchgear walima transformateur windings datugulenw na, oksizɛni sɔrɔli dan ye yɔrɔ minnu na, funteni kɔrɔya kɛcogo bɛ danfaraba don ni fiɲɛ dafalenw ye. Kɔlɔsiliw y’a jira ko PTFE ka funteni tiɲɛni hakɛ min bɛ azote la, o bɛ bɛn fiɲɛ ta hakɛ tannan kelen ma ni funteni kelen ye. O kɔrɔ ye ko ni fɛnɲɛnamafagalanw ye minnu sirilen don ni hɛrɛmɛtiki ye, PTFE kasɛti bɛ se ka baara kɛ waati jan kɔnɔ hali ni funteni bɛ tɛmɛ 260°C kan dɔɔnin. Nka, ni tiɲɛni daminɛna, a kɔfɛfɛnw i n’a fɔ karɔbɔli fluoride ni perfluoroisobutylene, olu bɛ bagaba lase mɔgɔ ma, wa u bɛ nɛgɛw tiɲɛ. O la, a nafa ka bon kosɛbɛ ka a lajɛ ko a kɛcogo funteni bɛ to ka tɛmɛ a tiɲɛni hakɛ kan kosɛbɛ – lakana hakɛ min bɛ se 30-50°C ma, o de ka ɲi ka ɲɛsin insulasi kɔrɔlen ma min bɛ se ka kɛ ni tensionba ye.
Farati minnu bɛ kɛ ka caya, olu ka jogo
Signal Attenuation and Distortion: PTFE standard ka dielectric constant (Dk) bɛ daminɛ 2,0 na ka se 2,6 ma. Fɛn minnu bɛ Dk la, olu bɛ se ka kɛ sababu ye ka taamasiɲɛw dɔgɔya ani k’u tiɲɛ u ci waati la – o ye ko gɛlɛnba ye RF ni mikrowɛn baarakɛcogo la.
