Nei Iyo Cable Insulation Layer Yakakosha Pakuita?

Iyo yakakosha chimiro chetambo yemagetsi inoumbwa nezvikamu zvina: waya core (conductor), insulation layer, shielding layer uye inodzivirira layer. Iyo insulation layer ndiyo yekuparadzaniswa kwemagetsi pakati petambo yepakati uye pasi uye zvikamu zvakasiyana zvewaya core kuti ive nechokwadi chekufambiswa kwesimba remagetsi, uye chikamu chakakosha chesimba retambo tambo.

Basa reiyo insulation layer:

Nheyo yetambo ndeye conductor. Kuti udzivise kukuvadzwa kwemidziyo kunokonzerwa nekupfupika kwewaya dzakafumurwa uye kukuvadza kune vanhu kunokonzerwa newaya dzinopfuura magetsi ekuchengetedza, inodzivirira inodzivirira layer inofanirwa kuwedzerwa kune tambo. Iro resistivity yemagetsi yesimbi conductor mutambo iduku zvikuru, uye magetsi ekudzivirira ekudzivirira akakwirira zvikuru. Chikonzero nei iyo insulator ichigona kuvharirwa imhaka yekuti: izvo zvakanaka uye zvakaipa zvinochaja mumamorekuru echidziviriro zvakasungwa zvakasimba, zvimedu zvinochajwa zvinogona kufamba zvakasununguka zvishoma, uye resistivity yakakura kwazvo, saka kazhinji, iyo macro ikozvino inoumbwa neiyo yemahara yekuchaja mafambiro pasi pechiito chekunze kwegetsi munda inogona kufuratirwa, uye inoonekwa sechinhu chisingaiti. Kune ma insulators, pane voltage yekuputsika inopa maerekitironi simba rakakwana kuti aafadze. Kana simba rekuputsa rapfuura, zvinhu hazvichadzikisi.

Chii chinokonzeresa kusakwana kwehukobvu hwekuisa patambo?

Pfupisa hupenyu hwesevhisi yewaya uye zvigadzirwa zvetambo, kana iyo yakaonda poindi yetambo sheath isingaite zvinodiwa, mushure mekushanda kwenguva refu, kunyanya munzvimbo yakavigwa, yakanyura, yakavhurika kana inoora, nekuda kwekureba kwenguva refu kwekunze svikiro, iyo insulation level uye chiyero chemuchina cheiyo nhete ye sheath ichaderedzwa. Routine sheath test yekuona kana mutsara kutadza kudzika, iyo yakaonda poindi inogona kuputswa, iyo inodzivirira mhedzisiro yetambo sheath icharasika. Mukuwedzera, kushandiswa kwemukati hakugoni kuregererwa, tambo uye tambo yenguva yakareba simba ichabudisa kupisa kwakawanda, kuchapfupisa hupenyu hwebasa rewaya netambo. Kana mhando yacho isiri kusvika pachiyero, inokonzeresa moto uye dzimwe njodzi dzekuchengetedza.

Wedzera kuomarara kwemaitiro ekuisa, mukugadzika maitiro kunofanirwa kufunga nezvekusiya gap, kuitira kuti iparadze kupisa kunogadzirwa mushure metambo uye tambo simba, ukobvu hwesheti hwakanyanya kukora huchawedzera kuoma kwekuisa, saka ukobvu hwesheath hunoda kuteedzera kwakasimba zvinoenderana nezvinodiwa, zvikasadaro haigone kuita basa mukudzivirira waya netambo. Imwe yehunhu hwemhando yechigadzirwa inoratidzwa mukuonekwa kwemhando yechigadzirwa. Ingave tambo yemagetsi kana tambo yakapfava yejira, kunaka kweiyo insulation layer inofanirwa kutariswa mukugadzirwa, uye inofanirwa kunyatso kudzora uye kuyedzwa.

Zvichida vanhu vazhinji vachave nekusahadzika, sezvo basa rekudzivirira rakanyanya kukura, pamusoro petambo yekuvhenekesa uye yakaderera-voltage tambo yakafukidzwa nehupamhi hwepurasitiki kana rubber insulation, uye iyo yakakwirira-voltage tambo mumunda haina kuvharwa nekudzivirira.

Nekuti pakukwira kwevoltage yakawandisa, zvimwe zvinhu zvinogara zvichidzivirira, senge rabha, mapurasitiki, huni dzakaoma, nezvimwewo, zvinozovawo maconductors, uye hazvizove neinodzivirira. Kuputira insulation patambo dzehigh-voltage kutambisa mari nezviwanikwa. Iyo yepamusoro-yepamusoro-voltage waya haina kuvharwa nekudzivirira, uye kana yakamiswa pashongwe yakakwirira, inogona kubuda magetsi nekuda kwekusangana neshongwe. Kuti udzivise chiitiko ichi, iyo yakakwira voltage waya inogara yakamiswa pasi peakareba akateedzana akanyatso insulated porcelain mabhodhoro, kuitira kuti iyo yakakwirira voltage waya inovharirwa kubva pashongwe. Mukuwedzera, paunenge uchiisa tambo dze-high-voltage, usadzikwevera pasi. Zvikasadaro, nekuda kwekukweshana pakati pewaya nepasi, iyo yekutanga yakatsetseka insulation layer inokuvadzwa, uye kune akawanda maburrs, ayo anoburitsa tip discharge, zvichikonzera kuvuza.

Iyo yekuvharisa layer yetambo inoiswa maererano nezvinodiwa netambo. Mukuita kwekugadzira, vagadziri vanofanirwa kudzora ukobvu hwekudzivirira mukunyatsoenderana nemaitiro ekuita, kuwana yakazara maitiro manejimendi, uye ive nechokwadi chemhando yewaya netambo.
