PTFE Tape Obulabe mu High-Voltage & High-Frequency Enkola

Nga omukugu mu kukola... PTFE adhesive tape n'ebintu ebikwatagana n'okuziyiza, Jiangsu Aokai New Materials Technology Co., Ltd. egabana okumanya okukulu. Wadde nga PTFE tepu ya bbugumu eringi etwalibwa nga ya muwendo olw’ebintu byayo ebirungi ennyo ebya dielectric n’okunyweza ebbugumu, embeera enkambwe ey’okukola eya frequency enkulu ne voltage enkulu ereeta obulabe obuwerako obuyinza okubaawo.

Okutegeera obulabe buno – omuli okukaddiwa olw’ebbugumu eringi, okumenya kw’amasannyalaze, okufiirwa kwa frequency enkulu, n’ensonga z’obutonde – kyetaagisa nnyo mu nteekateeka y’enkola eyesigika.

Obulabe bw’amaanyi g’amasannyalaze

High-Voltage Breakdown: Obutambi bwa PTFE bulina obuziyiza obutono obw’okumenya kwa dielectric. Okugeza, olutambi olulina obuwanvu bwonna obwa mm 0.11 luyinza okuba ne vvulovumenti y’okumenya nga 6.1kV. Obugumu obutamala oba obucaafu obw’omunda (ebinnya bya ppini, ebicaafu) bisobola bulungi okuleeta okumenya kwa vvulovumenti ennene n’okulemererwa kw’ekiziyiza.

Partial Discharge (Corona Discharge): Mu mbeera za vvulovumenti ennene, obucaafu obw’okungulu (enfuufu, amabala g’amafuta) n’ebituli ebitonotono eby’empewo munda bikola ebifo ebikuŋŋaanyizibwamu ekifo ky’amasannyalaze, ekivaako okufulumya corona. Okufuluma okutambula obutasalako okumala ebbanga eddene kugenda kukendeera mpolampola oluwuzi oluziyiza, ekivaako okulemererwa nga tekunnabaawo.

Okwonooneka kw’ebintu ebiziyiza omuliro okuva mu nsonga z’obutonde:

• Obunnyogovu: Obunnyogovu bwe busukka ebitundu 85%, obuziyiza bw’okungulu bwa PTFE busobola okukka nnyo – okuva ku 10⊃1;7Ω okutuuka ku 10⊃1;⊃2;Ω – era vvulovumenti y’okumenya eyinza okukendeera ebitundu 30% okutuuka ku 50%.

• Ebicaafu: Enfuufu etambuza oba okufuuyira omunnyo ku ngulu wa tape kikola ebibanda ebitambuza, ne kivaamu amakubo g’amasannyalaze agakulukuta.

Mu byuma by’amasannyalaze ebya vvulovumenti eya waggulu, amaanyi ga dielectric aga PTFE tapes si muwendo ogutakyukakyuka wabula gasinziira nnyo ku mbeera z’okukozesa. Ku ddaala eriziyiza corona, abakola batera okuyingiza ebijjuza ebitali biramu nga mica oba obutundutundu bwa seramiki mu matrix ya PTFE. Ebijjuza bino bikola micro-interfaces nnyingi ezisaasaanya ekisengejjo kya chajingi n’okunyigiriza emirimu gy’okufulumya ekitundu. Nga olondawo PTFE tape ku mmotoka za inverter eza vvulovumenti eya waggulu (okugeza, 6kV okutuuka ku 10kV class), kirungi okukozesa corona-resistant PTFE tape nga eriko obuwanvu obutakka wansi wa 0.18mm n’okukakasa partial discharge inception voltage (PDIV) wansi w’ebbugumu eryennyini ery’okukola, kubanga PDIV etera okukendeera 20-30% ku 150°C bw’ogeraageranya n’ebbugumu erya bulijjo.

Obulabe bw’okutebenkera kw’ebbugumu

Okukaddiwa mu bbugumu erya waggulu: mu budde obutuufu obutambi bwa PTFE busobola okukola obulungi ku bbugumu eritasalako erya 260°C. Naye ebbugumu bwe lisukka 250°C (naddala okumpi ne 300°C), enjegere za molekyu zitandika okuvunda. Okuvunda kuno kukendeeza nnyo amaanyi ga dielectric era kuleeta obulabe bw’okulemererwa kwa insulation.

Thermal-Oxygen Synergistic Effect: Okugatta ebbugumu eringi ne oxygen kyanguya okukaddiwa kw’ebintu. Mu mbeera ey’ebbugumu n’obunnyogovu, okwonooneka kw’omulimu gw’okuziyiza vvulovumenti kuyinza okweyongera ebitundu 30% okutuuka ku 50% bw’ogeraageranya n’ebbugumu erikalu lyokka.

PTFE tape bwekozesebwa mu switchgear oba transformer windings eziggaddwa nga oxygen supply ekoma, enneeyisa y’okukaddiwa okw’ebbugumu eyawukana nnyo ku mbeera z’empewo enzigule. Okunoonyereza kulaga nti omutindo gw’okuvunda kw’ebbugumu mu PTFE mu nayitrojeni guli nga kimu kya kkumi ku ekyo ekiri mu mpewo ku bbugumu lye limu. Kino kitegeeza nti ku bitundu bya vvulovumenti eya waggulu ebisibiddwa mu ngeri ya hermetically, PTFE tape esobola okutuuka ku bulamu obuwanvu obw’okuweereza ne ku bbugumu erisukka katono ku 260°C. Naye okuvunda bwe kutandika, ebivaamu nga carbonyl fluoride ne perfluoroisobutylene biba bya butwa nnyo era bivunda ebyuma ebikwatagana. N’olwekyo, kikulu nnyo okulaba nti ebbugumu ly’okusiiga lisigala wansi nnyo w’ekipimo ky’okuvunda – obukuumi bwa 30-50°C bwe kirungi ku kuziyiza okukulu okwa vvulovumenti enkulu.

Obulabe obw’engeri ez’emirundi egy’amaanyi

Signal Attenuation and Distortion: Ekikyukakyuka kya dielectric constant (Dk) ekya standard PTFE kiva ku 2.0 okutuuka ku 2.6. Ebintu ebirina okukyama okuyitiridde mu Dk bisobola okuleeta okukendeeza n’okukyusakyusa obubonero bwa frequency enkulu mu kiseera ky’okutambuza – ensonga enkulu eri enkola ya RF ne microwave.

Effect y’okukola ebbugumu: PTFE erina tangent y’okufiirwa kwa dielectric eya wansi ennyo (tan δ), okutwalira awamu wansi wa 0.0025. Naye singa ensonga y’okufiirwa eba waggulu nnyo (olw’obucaafu oba okulongoosebwa okutali kutuufu), ebbugumu erisukkiridde lijja kukolebwa wansi w’ekifo ky’amasannyalaze ekya firikwensi enkulu. Kino eky’okwebuguma kyanguya okukaddiwa kw’ebintu era kiyinza okuvaako okudduka okw’ebbugumu.

Obulabe bw’okutuukagana n’embeera z’ebyuma n’obutonde bw’ensi

Okwonooneka kw’okunyigirizibwa kw’ebyuma: Okusika n’okusikagana okuwangaala nga ossaako oba nga kikola kuyinza okuleeta enjatika entonotono n’okusika munda mu kintu, okwonoona omulimu gw’okuziyiza okutwalira awamu. Okukoona oba empenda ezisongovu olina okwewalibwa.

Chemical & Radiation Corrosion: Ebikozesebwa eby’amaanyi ebikulukuta nga ebyuma bya alkali ebisaanuuse ne hydrocarbons ezirimu chlorinated, wamu n’obusannyalazo obw’amaanyi amangi obuyitiridde (okusukka 104 Gy), bijja kusaanyaawo ensengekera ya molekyu ya PTFE era bikendeeze nnyo ku maanyi gaayo aga dielectric.

Okulemererwa kw’okusiiga: Okulonda okwesiiga mu ngeri etali ntuufu (okugeza, ebisiiga ebikolebwa mu acrylic) kuyinza okugonza n’okufiirwa okunyweza wansi w’ebbugumu eringi, ekivaako okusengulwa kwa ttaapu, okusumululwa, oba okwekulukuunya – naddala ekizibu mu nkola eziyimiridde oba ezikankana.

Low-Temperature Brittleness: Obutambi bwa PTFE obusinga bufiirwa okukyukakyuka ne bufuuka brittle nga ebbugumu likka wansi wa -70°C. Wadde nga tekitera kubaawo mu kukozesa amasannyalaze, kino kikulu eri ebyuma eby’ebweru oba eby’omu bwengula ebibeera mu mbeera ennyogovu ennyo.

Okumaliriza – Okulonda Okumanya Akabi Kukakasa Obwesigwa

Okukozesa PTFE adhesive tape mu kukola kwa vvulovumenti eya waggulu ne frequency enkulu kyetaagisa okulowooza ennyo ku nsonga eziwera ez’akabi. Nga bategeera ekkomo ly’amaanyi g’amasannyalaze, enneeyisa y’okukaddiwa kw’ebbugumu, eby’obugagga bya dielectric ebya frequency enkulu, n’obuwulize bw’obutonde, bayinginiya basobola okulonda ekigero kya tape ekituufu – oba okusaba eby’okugonjoola ebirongooseddwa – okwewala okulemererwa nga tekunnabaawo.
