Maumbirwo etambo yacho anoita seari nyore, kutaura chokwadi, chikamu chimwe nechimwe chayo chine basa rayo rakakosha, saka chinhu chimwe nechimwe chinofanira kusarudzwa nokungwarira pakugadzira tambo yacho, kuitira kuti tambo yakagadzirwa nezvinhu izvi ive nechokwadi chekuti yakavimbika panguva yekushanda kwayo.
1. Zvinhu zvemutyairi
Kare, zvinhu zvaishandiswa pakufambisa tambo dzemagetsi zvaive mhangura nearuminiyamu. Sodium yakamboedzwawo kwenguva pfupi. Mhangura nearuminiyamu zvine simba remagetsi riri nani, uye huwandu hwemhangura hushoma kana huchitumira magetsi akafanana, saka dhayamita yekunze yemutyairi wemhangura idiki pane yemutyairi wearuminiyamu. Mutengo wearuminiyamu wakaderera zvakanyanya pane mhangura. Pamusoro pezvo, nekuti huwandu hwemhangura hwakakura kupfuura hwearuminiyamu, kunyangwe simba rekutakura magetsi rakafanana, chikamu chemutyairi wearuminiyamu chakakura kupfuura chemutyairi wemhangura, asi tambo yemutyairi wearuminiyamu ichiri yakareruka kupfuura tambo yemutyairi wemhangura.
2. Zvinhu zvekudzivirira kupisa
Kune zvinhu zvakawanda zvinodzivirira zvinogona kushandiswa netambo dzemagetsi dzeMV, kusanganisira zvinhu zvinodzivirira mapepa zvakabikwa zvine tekinoroji, izvo zvave zvichishandiswa zvinobudirira kwemakore anopfuura zana. Nhasi, zvinodzivirira polymer zvakabviswa zvave kugamuchirwa nevakawanda. Zvinhu zvinodzivirira polymer zvakabviswa zvinosanganisira PE(LDPE neHDPE), XLPE, WTR-XLPE neEPR. Zvinhu izvi zvinodzivirira thermoplastic pamwe nethermosetting. Zvinhu zvinodzivirira thermoplastic zvinoshanduka kana zvadziiswa, nepo zvinhu zvinodzivirira thermoset zvichiramba zvakaita pakupisa kwekushanda.
2.1. Kudzivirira jira kubva pamapepa
Pakutanga kushanda kwavo, tambo dzakaputirwa nepepa dzinotakura mutoro mudiki chete uye dzinochengetwa zvakanaka. Zvisinei, vashandisi vemagetsi vanoramba vachiita kuti tambo dzakaputirwa dziwedzere mutoro, mamiriro ekutanga ekushandiswa haachakodzeri zvinodiwa netambo iripo, saka ruzivo rwepakutanga rwakanaka harugoni kuratidza kushanda kwetambo mune ramangwana kunofanira kunge kwakanaka. Mumakore achangopfuura, tambo dzakaputirwa nepepa hadziwanzo shandiswa.
2.2.PVC
PVC ichiri kushandiswa sechinhu chinodzivirira tambo dze 1kV dzine voltage shoma uye zvakare chinhu chinovhara tambo. Zvisinei, kushandiswa kwePVC mukudzivirira tambo kuri kutsiviwa nekukurumidza neXLPE, uye kushandiswa mu sheath kuri kutsiviwa nekukurumidza ne linear low density polyethylene (LLDPE), medium density polyethylene (MDPE) kana high density polyethylene (HDPE), uye tambo dzisiri dzePVC dzine mitengo yakaderera yehupenyu.
2.3. Polyethylene (PE)
Polyethylene yakaderera (LDPE) yakagadzirwa muma1930 uye ikozvino inoshandiswa se base resin yezvinhu zvinobatanidzwa ne crosslinked polyethylene (XLPE) uye tree-linked polyethylene (WTR-XLPE) zvisingapindi mvura. Mumamiriro e thermoplastic, tembiricha yepamusoro yekushanda kwe polyethylene i75 ° C, iyo yakaderera pane tembiricha yekushanda ye paper insulated cables (80~90 ° C). Dambudziko iri rakagadziriswa nekuuya kwe cross-linked polyethylene (XLPE), iyo inogona kusangana kana kupfuura tembiricha yekushanda ye paper-insulated cables.
2.4.Polyethylene yakabatana nemuchinjikwa (XLPE)
XLPE chinhu chinogadzirisa kupisa chakagadzirwa nekusanganisa polyethylene yakaderera (LDPE) nechinosanganisa mvura (seperoxide).
Tembiricha yepamusoro yekushanda kwetambo yeXLPE insulated ndeye 90 ° C, bvunzo yekuwedzeredza inosvika 140 ° C, uye tembiricha yepfupi inogona kusvika 250 ° C. XLPE ine hunhu hwakanaka hwe dielectric uye inogona kushandiswa muhuwandu hwemagetsi kubva pa600V kusvika 500kV.
2.5. Muti unodzivirira mvura Polyethylene yakabatana neCross-linked (WTR-XLPE)
Kushandiswa kwemiti yemvura kunoderedza hupenyu hwetambo yeXLPE. Kune nzira dzakawanda dzekuderedza kukura kwemiti yemvura, asi imwe yenzira dzinogamuchirwa ndeyekushandisa zvinhu zvakagadzirwa nehunyanzvi hwekudzivirira kukura kwemiti yemvura, zvinonzi polyethylene WTR-XLPE, iyo inodzivirira mvura.
2.6. Rabha yeEthylene propylene (EPR)
EPR chinhu chinogadzirisa thermosetting chakagadzirwa ne ethylene, propylene (dzimwe nguva monomer yechitatu), uye copolymer yemamonomer matatu inonzi ethylene propylene diene rubber (EPDM). Mukati mekupisa kwakakura, EPR inogara yakapfava uye ine resistance yakanaka ye corona. Zvisinei, kurasikirwa kwe dielectric kwezvinhu zveEPR kwakanyanya kupfuura kweXLPE neWTR-XLPE.
3. Maitiro ekudzivirira kupisa
Maitiro ekubatanidza zvinhu anoenderana nepolymer inoshandiswa. Kugadzirwa kwemapolymer akabatana kunotanga nepolymer yematrix uye zvinozowedzera zvinosimbisa uye zvinobatanidza zvinhu kuti zvigadzire musanganiswa. Maitiro ekubatanidza zvinhu anowedzera nzvimbo dzekubatanidza kune chimiro chemamorekuru. Kana zvangobatanidzwa, cheni yemamorekuru yepolymer inoramba yakabatana, asi haigone kuchekwa zvachose kuita fluid melt.
4. Zvinhu zvekudzivirira nekudzivirira dhayakita
Chidziviriro chekudzivirira chinopfuudza mhepo chinoburitswa pamusoro pekunze kwemuchina wekufambisa mhepo nechinhu chinodzivira mhepo kuti chienderane nemagetsi uye kuti chidziviriro chemagetsi chigare muchikamu chepakati chemuchina wekufambisa mhepo. Chidziviriro ichi chine giredhi reinjiniya rezvinhu zvitema zvekabhoni kuti chidziviriro chetambo chigone kuenderera mberi zvakanaka mukati mehuwandu hunodiwa.
