Zingwe zamagetsi zapakati zimakhala ndi pakati pa 6 kV ndi 33kV.Amapangidwa makamaka ngati gawo lamagetsi opangira magetsi ndikugawa ntchito zambiri monga zofunikira, petrochemical, mayendedwe, kuyeretsa madzi oyipa, kukonza chakudya, misika yamalonda ndi mafakitale.
Nthawi zambiri, amagwiritsidwa ntchito kwambiri m'makina okhala ndi voteji mpaka 36kV ndipo amagwira ntchito yofunika kwambiri pakupangira magetsi ndi ma network ogawa.
01.Standard
Ndi kufunikira kwapadziko lonse lapansi kwa zingwe zamagetsi zapakati, kutsata miyezo yamakampani kukukhala kofunika kwambiri.
Zofunikira kwambiri zama chingwe chapakati pamagetsi ndi:
IEC 60502-2: Zingwe zamagetsi zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi, zokhala ndi voliyumu yofikira mpaka 36 kV, kapangidwe kake komanso kuyesa kosiyanasiyana, kuphatikiza zingwe zapakati limodzi ndi zingwe zapakatikati;zingwe zankhondo ndi zingwe zopanda zida, mitundu iwiri Zida zankhondo "lamba ndi zida za waya" zikuphatikizidwa.
TS EN 60754 IEC / EN 60754: idapangidwa kuti iwunike zomwe zili mu mpweya wa halogen acid, ndipo cholinga chake ndi kudziwa mipweya ya asidi yomwe imatulutsidwa pamene zotchingira, zotsekemera, ndi zina zotere zikuyaka.
TS EN 60332 IEC / EN 60332 Muyezo wa kufalikira kwa lawi mu utali wonse wa chingwe pakayaka moto.
TS EN 61034 IEC / EN 61034: Imatchula kuyesedwa kuti mudziwe kuchuluka kwa utsi wa zingwe zoyaka pamikhalidwe yodziwika.
BS 6622: Imakwirira zingwe zama voltages ovotera mpaka 36 kV.Imakhudza kukula kwa mapangidwe ndi kuyesa, kuphatikiza zingwe zapakati limodzi ndi zingwe zambiri;zingwe zokhala ndi zida zokha, mitundu ya mawaya okhala ndi mawaya okha ndi zingwe zokhala ndi PVC.
- BS 7835: Imakwirira zingwe zama voltages ovotera mpaka 36 kV.Imakhudza kukula kwa mapangidwe ndi kuyesa, kuphatikiza chingwe chimodzi, zingwe zokhala ndi zida zambiri, zingwe zokhala ndi zida zokha, zingwe zokhala ndi zida zokha, zingwe zopanda utsi wopanda halogen.
BS 7870: ndi mndandanda wamiyezo yofunika kwambiri pazingwe zotsika komanso zapakatikati zamagetsi a polymer kuti zigwiritsidwe ntchito ndi makampani opanga magetsi ndi kugawa.
02.Mapangidwe ndi zinthu
Chingwe chapakati chamagetsimapangidwe amatha kubwera mosiyanasiyana komanso mosiyanasiyana.Zomwe zimapangidwira zimakhala zovuta kwambiri kuposa zingwe zotsika kwambiri.
Kusiyanitsa pakati pa zingwe zapakati pamagetsi ndi zingwe zotsika kwambiri sikumangokhalira kupanga zingwe, komanso kuchokera kuzinthu zopangira ndi zopangira.
Mu zingwe zapakati pamagetsi, njira yotsekera ndi yosiyana kwambiri ndi yamagetsi otsika, kwenikweni:
- Chingwe chapakati chamagetsi chimakhala ndi zigawo zitatu m'malo mwa wosanjikiza umodzi: wosanjikiza wotchinga, zotchingira zotchinga, zotchingira zotchinga.
- Njira yotchinjiriza ya ma voltages apakati imatheka pogwiritsa ntchito mizere ya CCV m'malo mwa ma extruder okhazikika, monga momwe zimakhalira ndi zingwe zotsika.
- Ngakhale kutchinjiriza kuli ndi dzina lofanana ndi chingwe chotsika chamagetsi (monga XLPE), zopangirazo ndizosiyana kuti zitsimikizire kutsekereza koyera.Mitundu ya masterbatches ya zingwe zotsika mphamvu ndizosaloledwa kuzindikiritsa poyambira.
- Zowonetsera zitsulo zimagwiritsidwa ntchito popanga zingwe zapakati pamagetsi amagetsi otsika operekedwa kuzinthu zina.
03. Mayeso
Zida zamagetsi zamagetsi zapakatikati zimafunikira mayeso akuzama kuti awunike zida zamtundu uliwonse ndi chingwe chonse molingana ndi zovomerezeka zonse zama chingwe.Zingwe zamagetsi zapakati zimayesedwa kuti zikhale zawomagetsi, makina, zipangizo, mankhwala ndi moto chitetezo ntchito.
Zamagetsi
Kuyesa Kwapang'ono Kutaya - Kupangidwa kuti mudziwe kukhalapo, kukula kwake, ndikuwona ngati kukula kwa kutuluka kumaposa mtengo wotchulidwa pamagetsi enaake.
Mayeso Oyendetsa Magalimoto Otentha - Amapangidwa kuti awone momwe chingwe chimayankhira pakusintha kwa kutentha kosalekeza muutumiki.
Mayeso a Impulse Voltage - adapangidwa kuti awone ngati chingwe cha chingwe chingathe kupirira kugunda kwamphezi.
Mayeso a Voltage Maola a 4 - Tsatirani kutsatizana kwa mayeso pamwambapa kuti mutsimikizire kukhulupirika kwamagetsi kwa chingwe.
Zimango
Kuyesa kwa shrinkage - kupangidwa kuti mudziwe momwe zinthu zimagwirira ntchito, kapena zotsatira pazigawo zina pakupanga chingwe.
Kuyesa kwa Abrasion - Nyanga zachitsulo zofewa zimakakamizidwa kunyamula ngati muyezo kenako zimakokedwa mopingasa pa chingwecho m'njira ziwiri zotsutsana mpaka mtunda wa 600mm.
Heat Set Test - Adapangidwa kuti awone ngati pali kulumikizana kokwanira muzinthuzo.
Chemical
Mipweya Yowononga ndi Acid - Yopangidwira kuyeza mipweya yotulutsidwa ngati zitsanzo za chingwe zimayaka, kutengera zochitika zamoto, ndikuwunika zonse zomwe sizitsulo.
Moto
Kuyesa Kufalikira kwa Flame - Kupangidwa kuti kuwunika ndikumvetsetsa magwiridwe antchito a chingwe poyesa kufalikira kwa lawi lamoto utali wa chingwe.
Kuyesa Kutulutsa Utsi - Kupangidwa kuti kuwonetsetse kuti utsi womwe umapangidwa supangitsa kuti magetsi azitsika kwambiri kuposa zomwe zatchulidwa.
04.Kuwonongeka kofala
Zingwe zabwino kwambiri zimachulukitsa kulephera ndikuyika mphamvu ya wogwiritsa ntchito kumapeto.
Zifukwa zazikuluzikulu za izi ndi kukalamba msanga kwa zomangamanga za chingwe, maziko abwino a olowa kapena makina othetsa chingwe, zomwe zimapangitsa kuti kudalirika kuchepetsedwa kapena kugwira ntchito moyenera.
Mwachitsanzo, kutulutsidwa kwa mphamvu zowonongeka pang'onopang'ono ndizomwe zimayambitsa kulephera, chifukwa zimapereka umboni wakuti chingwecho chikuyamba kuwonongeka, zomwe zingayambitse kulephera ndi kulephera, ndikutsatiridwa ndi magetsi.
Kukalamba kwa chingwe kumayamba ndi kukhudza kutsekereza kwa chingwe pochepetsa kukana kwamagetsi, chomwe ndi chizindikiro chachikulu chazovuta kuphatikiza chinyezi kapena matumba a mpweya, mitengo yamadzi, mitengo yamagetsi, ndi zovuta zina.Kuphatikiza apo, ma sheaths ogawanika amatha kukhudzidwa ndi ukalamba, kuonjezera chiopsezo cha zomwe zimachitika kapena dzimbiri, zomwe zingayambitse mavuto pambuyo pake.
Kusankha chingwe chapamwamba kwambiri chomwe chayesedwa bwino kumatalikitsa moyo wake, kumaneneratu kukonzanso kapena kusintha, ndikupewa kusokoneza kosafunikira.
05.Kuyesa kwamtundu ndi kuvomereza kwazinthu
Kuyesa mafomu ndikothandiza chifukwa kumatsimikizira kuti chitsanzo china cha chingwe chimagwirizana ndi muyezo wina panthawi inayake.
Kuvomerezedwa kwazinthu za BASEC kumaphatikizapo kuwunika kokhazikika kwa dipatimenti kudzera pakuwunika pafupipafupi kwa njira zopangira, machitidwe owongolera komanso kuyesa kwazitsanzo za chingwe.
Mu chiwembu chovomerezeka cha mankhwala, zitsanzo zingapo zimayesedwa kutengera chingwe kapena mtundu womwe ukuwunikiridwa.
Njira yolimba kwambiri ya certification ya BASEC imatsimikizira wogwiritsa ntchito kuti zingwezo zimapangidwira ku miyezo yovomerezeka yamakampani, zimapangidwira pamlingo wapamwamba kwambiri ndipo zikugwira ntchito mosalekeza, zomwe zimachepetsa kwambiri chiopsezo cholephera.
