4. Kupesana nekutsvaga kwemagetsi
Kutsvaga, kana kuumbwa kwekutsvagira, ndiko kugadzirwa zvishoma nezvishoma kwenzira dzinoitisa pamusoro pechimiro chemapurasitiki mumamiriro ezvinhu akasanganiswa ekushushikana kwemagetsi uye zvakasvibiswa zvemagetsi. Zvekushandisa mapurasitiki ekusimbisa, emagetsi emagetsi ekuita anoenzaniswa neyemagetsi tracing index (CTI) Kutsvaga kwemagetsi, inonzi kutadza kwekutsvaga kwemagetsi, kureva, kuwanda, 0.5 A kana yakakura zvazvino zvinogara kune 2 s kana chiito; kana kuenderera mberi kupisa 2 s kana kupfuura. Kuti uve wakanyatsojeka, iyo bvunzo voltage renji ndeye00 ~ nePistrivity yeAnenge 3.95 OHM-M; Solution B is 0.1 Wt% Ammonium chloride + 0.5 wt% sodium diisobutylnaphthalene sulfonate ine purovha ye1,98 ohm-m; Solution B inonyanya kurwisa uye inowanzoteverwa netsamba m mushure mekukosha kweCTI. Mukuwedzera, pane pfungwa yePTI (chiratidzo chinotevera index), kana kusvetuka kutanga index, iyo iri yekudzikisira kwekunyepedzera kukosha kwezvinhu zvichidzivirira madonhwe makumi mashanu emadonhwe asina kuvhundutsa kutanga.
CTI kuyedza zviyero zvinosanganisira IEC 60112, ASTM D3336 uye GB / T 4207. Substrate Zvekushandisa (Flame Retirded, mapurasitiki, etcsezers, etc.) zvese zvinokanganisa cti; Kubva pane iyo maonero ekuumbwa uye kugadzirisa, kudzivisa kupatsanurana kwemamolekyu madiki, kuunganidzwa kwekaroni yemahara ndiyo kiyi yekudzivisa mamalekyudhi madiki, uye panguva imwe chete ichivandudza kutaridzika kweiyo gloss gloss uye blessness. Tora Crastin's Crastain® PBT semuenzaniso, iyo CTI iri pakati pegumi nemakumi matatu neshanu Uye zvakare, iyo cti yezvinhu zvakadai sePP uye LCP iri zvishoma kuderera, kunyanya nekuda kweiyo yepamusoro carbon yezvinyorwa zvemanyorerwo. Muchidimbu, yemidziyo yemagetsi uye yemagetsi, yepurasitiki yekusimbisa, kufunga kwese kweiyo substrate, kuumbwa uye kugadzirisa zvinhu.
5. arc kuramba
Plastiki Inoshanduka Zvigadzirwa Arc Kuramba (gomba rekuumba) nguva inodikanwa kuratidza (unit is s). Muedzo wacho unowanzoshandisa voltage yakakwira, zvidiki zviripo (12,5 kv voltage, 10 ~ 40 ma electrodes of the arc, kuburikidza neARC nguva yekuparadza zvishoma nezvishoma, iyo iripo Kuwedzera zvishoma nezvishoma, zvekuti zvinyorwa zvinoiswa pasi pemamiriro ezvinhu akanyanya kusvika kusvika pakuparadzwa kwechifungidziro, chinyorwa chenguva chakapfuura kubva kuchizvarwa cheArC kusvika pakuparadza kwezvinhu. Kuenzaniswa ne "Kupfuta ne" yakanyoroveswa "kweiyo arc kurwisa kwe" kupisa kurwisa "ndiko kuongorora zvivakwa zvekusimbisa kwezvinhu nekugadzira magetsi arc zvakare uye zvakare.
Mitemo yekubvunzwa mainc yeARC irikupesana ndeye IEC 61621, ASTM D495 uye GB / T 1411, uye ARC Ristance Yemapurasitiki Inosimbisa Midziyo kubva kumasekondi kusvika pamasekonzi maviri kana maviri. Iyo yakareba iyo arc kuramba nguva, iri nani pamusoro pekusimbisa kwekuita. Zvakafanana ne CTI
6. Corona Resistance
Yakakwirira-voltage yakapihwa mutumbi, yakadai seyakawandisa masimba emabhokisi uye maContage avo, kutenderedza gasi mumunda wakasarudzika wemahara, anozivikanwa se corona (corona). Zvishandiso zvemapurasitiki mune zve corona zvichave zvichizarirwa zvishoma nezvishoma, kunyanya nekuda kwekurohwa kwakananga kwekuparadzwa kwemari, kupisa kwakanyanya, ozone uye imwe uye imwe oxidizing mhedzisiro. Corona kupesana (Corona kupesana) kunoreva zvinhu zvekusimbisa ne corona discharge kunogona kuramba kunaka kwechimiro chekuderera.
Corona Kupesana bvunzo zviyero ndeye I IC 60343, ASTM D2275 uye GB / T 22689 Corona-inodzivirira mapurasitiki ekusimbisa zvinhu, kunyanya mafirimu anoramba eCorona, anotamba basa rakakosha mukukwira-famba-famba magetsi emagetsi. Kapt's Kapton® CRC Polyimide firimu inotengeswa kune yayo yakanaka Corona Kapton® 100CTC ine yakakwira voltage nguva muHupombwe yekubvisa (1,250 vac / 1050 hz) kupfuura yakajairika polyimide film kapton ® 100n ®. Zvakakodzera kutaura kuti kuwedzera kweInorganic naneopartticles inzira yakakosha yekuvandudza iyo Corona kuramba zvinhu zvemapurasitiki.
7. Yakatemerwa discharge
Chikamu chePD (PD) ndeyemhando yemagetsi umo iyo insulation pakati pevatori vezvikamu zvinongova zvishoma nezvishoma nemunda yemagetsi. Kupararira kwechidimbu kunowanzoitika kuparara, chikonzero chacho chinonyanya kukonzerwa nekuvapo kwenhau dzisina kuenzana Aya mabhuruu kana mhepo yemhepo pane rimwe ruoko, kusimbisa zvinhu mukugadzira maitiro hazvidzivirirwe, kune rumwe rutivi, kwenguva refu kushanda nekuda kwekudziya kwekushanduka kwakakonzerwa nemuchina wekushambidzika uye zvimwe zvinhu. Kuburitswa kwechidimbu kuchakurumidza kukwegura uye kuputswa kwezvinhu zvekushandisa, muchimiro chekugadzira, kusarudzwa kwezvinhu uye kugadzira hakufanirwe kufuratirwa. Zvekushandisa epurasitiki ekusimbisa, maitiro ekugadzira uye maitiro ekugadzira anofanirwa kutariswa pamwe chete kuti vadzivise zvakawandisa zvekugadzira, jekiseni rakakomberedzwa, uye zvimwe zvikanganiso mune izvo zvinyorwa, uye kuwedzera chikamu chemuzambiringa.
Iyo mainini bvunzo zviyero zvekuparadzanisa eic 60270, ASTM D1868 uye GB / THE COPLEAGE, iyo nguva yekuita yemamiriro ekunze ichakanganisa mhedzisiro yechidimbu kuraswa. Uye zvakare, kunze kwemagetsi kuyerwa nzira dzakadai sekusvitsa nzira yazvino, Ultrasonic nzira uye mwenje wave nzira nzira inogona zvakare kushandiswa kuti uone kusarudzika. Iyo yunivhesiti yekubvisa courcharge idhi ; Kazhinji, huwandu hwechidimbu chechigadzirwa chechigadzirwa chekusimbisa chinodiwa kuti chisave 3 pc (3 × 10-12 c).
Mukupfupikisa, kuti zvinhu zvemapurasitiki zvinonyanya kusimbisa, zvivakwa zvemagetsi zvinonyanya kusanganisira kupokana uye kuramba simba, kuramba kurwisa, kuramba Corona, kupokana neCorona, kudzima zvazvino uye kusimuka. Muchokwadi, kune zvigadzirwa zvakasiyana zvemagetsi, zvigadzirwa zvemagetsi uye zvishandiso, pane zvinodiwa zvakasiyana uye zviyero zvezvivakwa zvemagetsi zvemagetsi zvechigadzirwa. Naizvozvo, nekuda kwekusimbisa kwakazara kwezvigadzirwa izvi, kusarudzwa kwepurasitiki zvinhu zvekushandisa uye dhizaini yemisimboti chimiro chinofanira kufungwa nezvazvo. Muchidimbu, chemagetsi epurasitiki, kusarudzwa kwezvinhu zvekutevera nheyo dzenyama
