Izintambo zikagesi ezimaphakathi zinebanga likagesi phakathi kuka-6 kV no-33kV.Akhiqizwa kakhulu njengengxenye yokukhiqiza amandla kanye namanethiwekhi okusabalalisa kwezinhlelo zokusebenza eziningi ezifana nezinsiza, i-petrochemical, ezokuthutha, ukuhlanzwa kwamanzi angcolile, ukucubungula ukudla, izimakethe zezentengiselwano nezimboni.
Ngokuvamile, asetshenziswa kakhulu ezinhlelweni ezinebanga lamandla kagesi afinyelela ku-36kV futhi adlala indima ebalulekile ekuphehlisweni kwamandla namanethiwekhi okusabalalisa.
01.Okujwayelekile
Ngokukhula kwesidingo somhlaba wonke samakhebuli kagesi aphakathi nendawo, ukuvumelana nezindinganiso zomkhakha kuya ngokuya kubaluleke kakhulu.
Imibandela ebaluleke kakhulu yamakhebuli kagesi aphakathi yilezi:
I-IEC 60502-2: Amakhebuli aphakathi nendawo asetshenziswa kakhulu emhlabeni, ane-voltage elinganiselwe efika ku-36 kV, uhla olubanzi lokuklama nokuhlola, okuhlanganisa izintambo eziwumgogodla owodwa kanye nezintambo eziningi-core;izintambo zezikhali kanye nezintambo ezingenazikhali, izinhlobo ezimbili I-armor "ibhande lezikhali zocingo" ifakiwe.
- I-IEC/EN 60754: idizayinelwe ukuhlola okuqukethwe kwamagesi e-halogen acid, futhi ihlose ukunquma amagesi e-asidi akhishwa lapho okokufaka, ukushefa, njll. izinto zokwenziwa zivutha.
- I-IEC/EN 60332: Isilinganiso sokusakazeka kwelangabi kubo bonke ubude bekhebula uma kuba nomlilo.
I-IEC/EN 61034: icacisa ukuhlolwa kokunquma ukuminyana kwentuthu yezintambo ezivuthayo ngaphansi kwezimo ezithile.
- I-BS 6622: Imboza izintambo zama-voltage akalwe afika ku-36 kV.Ihlanganisa ububanzi bokuklama nokuhlola, okuhlanganisa izintambo eziwumgogodla owodwa kanye namakhebula amaningi;amakhebuli ahlomile kuphela, izinhlobo ze-armored kuphela kanye nezintambo eziboshwe nge-PVC.
- BS 7835: Imboza izintambo zama-voltage akalwe afika ku-36 kV.Ihlanganisa ububanzi bokuklama nokuhlola, okuhlanganisa izintambo eziwumgogodla owodwa, izintambo eziningi, amakhebuli ahlomile kuphela, amakhebuli ezikhali kuphela, izintambo ezingenantuthu ephansi ye-halogen.
- I-BS 7870: iwuchungechunge lwamazinga abaluleke kakhulu amakhebuli e-polymer afaka amandla kagesi aphansi naphakathi ukuze asetshenziswe izinkampani zokuphehla ugesi kanye nokusabalalisa.
02.Isakhiwo kanye nempahla
Intambo kagesi emaphakathiimiklamo ingaba ngosayizi nezinhlobo ezahlukene.Isakhiwo siyinkimbinkimbi kakhulu kunezintambo ezine-voltage ephansi.
Umehluko phakathi kwezintambo zamandla kagesi aphakathi nendawo kanye nezintambo zamandla kagesi aphansi akukhona nje kuphela ukuthi amakhebuli akhiwa kanjani, kodwa futhi kusukela kunqubo yokukhiqiza kanye nezinto zokusetshenziswa.
Ezintamboni zamandla kagesi aphakathi, inqubo yokufaka ihluke kakhulu kuleyo yezintambo zamandla kagesi aphansi, eqinisweni:
- Ikhebula le-voltage emaphakathi liqukethe izendlalelo ezintathu esikhundleni sesendlalelo esisodwa: ungqimba oluvikela ikhondatha, impahla evikelayo, ungqimba oluvikelayo.
- Inqubo yokufaka ama-voltage amaphakathi ifinyelelwa ngokusebenzisa imigqa ye-CCV esikhundleni sama-extruder avundlile avamile, njengoba kwenzeka kumakhebuli kagesi aphansi.
- Ngisho noma i-insulation inegama elifanayo nekhebula le-voltage ephansi (isb. i-XLPE), impahla eluhlaza ngokwayo ihlukile ukuze kuqinisekiswe ukugqunywa okuhlanzekile.Ama-masterbatches ombala wezintambo ezine-voltage ephansi awavunyelwe ukuhlonza okubalulekile.
- Izikrini zensimbi zivame ukusetshenziswa ekwakhiweni kwamakhebuli kagesi aphakathi kumakhebuli kagesi aphansi anikezelwe kuzinhlelo zokusebenza ezithile.
03.Isivivinyo
Imikhiqizo yekhebula kagesi kagesi emaphakathi idinga ukuhlolwa kohlobo okujulile ukuze kuhlolwe izingxenye ngazinye nayo yonke ikhebula ngokuvumelana nawo wonke amazinga okugunyazwa kwemikhiqizo yekhebula.Izintambo zamandla kagesi aphakathi ziyahlolwa ukuze zisebenzeimisebenzi kagesi, imishini, impahla, amakhemikhali kanye nokuvikela umlilo.
Ugesi
Ukuhlolwa Kokukhipha Ingxenye - Kuklanyelwe ukucacisa ubukhona, ubukhulu, kanye nokuhlola ukuthi ubukhulu bokukhishwa bungaphezu kwenani elishiwo le-voltage ethile.
Ukuhlolwa Kokuhamba Ngebhayisikili Okushisayo - Kuklanyelwe ukuhlola ukuthi umkhiqizo wekhebula usabela kanjani ekushintsheni kwezinga lokushisa okuqhubekayo enkonzweni.
I-Impulse Voltage Test – eklanyelwe ukuhlola ukuthi umkhiqizo wekhebula ungakwazi yini ukumelana nokwanda kokushaywa kombani.
Ukuhlola I-Voltage Amahora angu-4 - Landela ukulandelana kokuhlolwa okungenhla ukuze uqinisekise ubuqotho bukagesi bekhebula.
Omakhenikha
Ukuhlolwa kwe-shrinkage - okuklanyelwe ukuthola ukuqonda ekusebenzeni kwempahla, noma imiphumela kwezinye izingxenye ekwakhiweni kwekhebula.
Ukuhlolwa Kwemihuzuko - Izimpondo zensimbi ezithambile ziphoqelelwa ukulayishwa njengezinga elijwayelekile bese zihudulwa ngokuvundlile kukhebula ngezindlela ezimbili eziphambene ukuya ebangeni elingu-600mm.
Ukuhlolwa Kwesethi Yokushisa - Kuklanyelwe ukuhlola ukuthi kukhona yini ukuphambana okwanele kokubalulekile.
Amakhemikhali
Amagesi Abolayo Ne-Acid - Aklanyelwe ukukala amagesi akhululwa njengoba amasampula ekhebula esha, alingise izimo zomlilo, futhi ahlole zonke izingxenye ezingezona ezensimbi.
Umlilo
Ukuhlolwa Kokusabalalisa Ilangabi - Kuklanyelwe ukuhlola nokuqonda ukusebenza kwekhebula ngokulinganisa ukusabalala kwelangabi ngobude bekhebula.
Ukuhlolwa Kokukhishwa Kwentuthu - Kuklanyelwe ukuqinisekisa ukuthi intuthu ekhiqizwayo ayibangeli amazinga aphansi okudlulisela ukukhanya kunamanani ashiwo afanelekile.
04.Ukungasebenzi kahle okuvamile
Amakhebuli ekhwalithi engeyinhle akhuphula izinga lokuhluleka futhi abeke ukunikezwa kwamandla kagesi omsebenzisi wokugcina engcupheni.
Izizathu eziyinhloko zalokhu ukuguga ngaphambi kwesikhathi kwengqalasizinda yekhebula, isisekelo esingesihle sekhwalithi yamajoyinti noma izinhlelo zokunqanyulwa kwekhebula, okuholela ekunciphiseni ukwethembeka noma ukusebenza kahle.
Isibonelo, ukukhululwa kwamandla okukhipha ingxenye kuyisandulela sokuhluleka, njengoba kunikeza ubufakazi bokuthi ikhebula liqala ukuwohloka, okuzoholela ekuhlulekeni nasekuhlulekeni, okulandelwa ukucisha kukagesi.
Ukuguga kwekhebula ngokuvamile kuqala ngokuthinta ukuvala ikhebula ngokunciphisa ukumelana nogesi, okuyinkomba ebalulekile yokukhubazeka okuhlanganisa umswakama noma amaphakethe omoya, izihlahla zamanzi, izihlahla zikagesi, nezinye izinkinga.Ngaphezu kwalokho, ama-sheaths ahlukanisiwe angathinteka ngokuguga, okwandisa ingozi yokusabela noma ukugqwala, okungabangela izinkinga kamuva enkonzweni.
Ukukhetha ikhebuli yekhwalithi ephezulu ehlolwe kahle kwelula impilo yayo, kubikezela ukulondolozwa noma ukushintshwa kwezikhawu, futhi kugwema ukuphazamiseka okungadingekile.
05.Ukuhlolwa kohlobo nokugunyazwa komkhiqizo
Ukuhlolwa kwefomu kuyasiza ngoba kuqinisekisa ukuthi isampula ethile yekhebula ithobelana nezinga elithile ngesikhathi esithile.
Ukugunyazwa komkhiqizo we-BASEC kufaka phakathi ukuqapha okuqinile komnyango ngokucwaningwa kwamabhuku okuvamile kwezinqubo zokukhiqiza, izinhlelo zokuphatha kanye nokuhlolwa okuqinile kwesampula yekhebula.
Kuhlelo lokugunyaza umkhiqizo, amasampuli amaningi ayahlolwa kuye ngekhebuli noma ububanzi obuhlolwayo.
Inqubo eqinile yesitifiketi se-BASEC iqinisekisa umsebenzisi wokugcina ukuthi amakhebuli akhiqizwa ngamazinga amukelekayo embonini, akhiqizwa ngezinga eliphezulu kakhulu futhi asebenza ngokuqhubekayo, anciphisa kakhulu ingozi yokwehluleka.
