Unyanzvi muMatafura Asingapindi Mvura

1. Chii chinonzi waya isingapindi mvura?
Tambo dzinogona kushandiswa mumvura dzinonzi tambo dzemagetsi dzisingapindi mvura (dzisingapindi mvura). Kana tambo yacho yaiswa pasi pemvura, inowanzo nyudzwa mumvura kana munzvimbo dzakanyorova, tambo yacho inofanirwa kuva nebasa rekudzivirira mvura (dzisingapindi mvura), kureva kuti, inofanirwa kuva nebasa rekudzivirira mvura zvizere, kuitira kudzivirira mvura kuti isanyure mutambo, zvichikonzera kukuvara kwetambo, uye kuona kuti tambo yacho iri pasi pemvura inoshanda kwenguva refu. Modhi yetambo isingapindi mvura inowanzoshandiswa ndeye JHS, inova yetambo isingapindi mvura ine rabha, tambo isingapindi mvura yakakamurwawo kuita tambo yemagetsi isingapindi mvura uye tambo yekombiyuta isingapindi mvura, nezvimwewo, uye vamiririri vemuenzaniso ndeve FS-YJY, FS-DJYP3VP3.

2. Rudzi rwechidziro chetambo isingapindi mvura
(1). Pamatambo ane musimboti mumwe chete, putiratepi inovhara mvura ine semi-conductorpachidzitiro chekudzivirira kupisa, putira zvakajairikatepi inovhara mvurakunze, wobva wadzvanya sheath yekunze, kuti uve nechokwadi chekuti shield yesimbi yakabatana zvizere, ingoputira tepi inovhara mvura iri semi-conductive kunze kweshield yekudzivirira, shield yesimbi haichaputiri tepi inovhara mvura, zvichienderana nemazinga ekushanda kwemvura, kuzadza kunogona kuzadzwa nefiller yakajairika kana water block filler. Lining yemukati nezvinhu zvekunze zvesheath zvakafanana neizvo zvakatsanangurwa mu single core cable.

(2). Rutivi rwetepi rwepurasitiki rwakaputirwa nearuminiyamu runoputirwa kwenguva refu mukati mechikamu chekunze kana chikamu chemukati chemukati sechikamu chisingapindi mvura.

(3). Bvisa sheath yekunze yeHDPE zvakananga patambo. Tambo yeXLPE insulated iri pamusoro pe110kV ine sheath yesimbi inosangana nezvinodiwa zvisingapindi mvura. Chidziviriro chesimbi hachipindi mvura zvachose uye hachipindi mvura zvakanaka. Mhando huru dzesheath yesimbi ndeidzi: sheath yealuminium inopiswa, sheath yelead inopiswa, sheath yealuminium inopiswa, sheath yesimbi inopiswa, sheath yesimbi inoputika, sheath yesimbi inotorwa inotonhora nezvimwewo.

3. Chimiro chetambo isingapindi mvura
Kazhinji kacho zvinokamurwa kuita zviviri: Vertical water resistance uye radial water resistance. Vertical water resistance ndiyo inowanzo shandiswashinda inovhara mvura, hupfu hwemvura uye tepi inovhara mvura, nzira yekudzivirira mvura iri muzvinhu izvi ine mvura inogona kuwedzera zvinhu, kana mvura ichibva kumucheto wetambo kana kubva musheath ikakanganisika, zvinhu izvi zvinokurumidza kuwedzera mvura kudzivirira kupararira kwakawanda pamwe chete netambo refu, kuti zvizadzise chinangwa chetambo refu isingapindi mvura. Kudzivirira mvura kwe radial kunonyanya kuwanikwa nekubvisa HDPE non-metallic sheath kana hot pressing, welding uye cold drawing sheath yesimbi.

4. Kupatsanurwa kwetambo dzisingapindi mvura
Kune mhando nhatu dzetambo dzisingapindi mvura dzinoshandiswa muChina:
(1). Waya inodzivirirwa nepepa remafuta ndiyo tambo inonyanya kubatwa nemvura. Zvinodzivirira kupisa kwayo nezvinokonzeresa mvura zvakazadzwa nemafuta etambo, uye kune jira resimbi (jaketi remutobvu kana jira realuminium) kunze kwejira rinodzivirira kupisa, iro riri jira rakanakisisa rinodzivirira mvura. Kare, tambo dzakawanda dzemugungwa (kana dzemumvura) dzaishandisa tambo dzinodzivirirwa nepepa remafuta, asi tambo dzinodzivirirwa nepepa remafuta dzinoganhurirwa nekudonha, pane dambudziko rekubuda kwemafuta, uye kugadzirisa kwacho hakuna kunaka, uye ikozvino hadzichashandiswi zvakanyanya.

(2). Waya yerabha ye ethylene propylene insulated inoshandiswa zvakanyanya mumitsetse yemagetsi yakaderera uye yepakati pasi pemvura inokonzerwa nekushanda kwayo kwepamusoro-soro kweinsulation pasina kunetseka nezve "muti wemvura". Waya yerabha isina mvura (Type JHS) inogona kushanda zvakachengeteka mumvura isina kudzika kwenguva yakareba.

(3). Waya yemagetsi inonyungudutswa nepolyethylene (XLPE) nekuda kwehunhu hwayo hwakanaka hwemagetsi, hwemakanika uye hwepanyama, uye maitiro ekugadzira ari nyore, chimiro chakareruka, kugona kukuru kwekutumira, kuisa nekugadzirisa zviri nyore, hazvigumiri pakudonha nezvimwe zvakanakira, zvinova zvinhu zvinonyanya kushandiswa zvekudzivirira, asi zvinonyanya kukanganiswa nehunyoro, mukugadzirwa uye mashandiro kana insulation iine mvura, Inowanzo pwanyika "muti wemvura", zvichipfupisa hupenyu hwebasa rewaya. Naizvozvo, waya inonyungudutswa nepolyethylene, kunyanya waya yemagetsi epakati nepamusoro pasi pesimba reAC voltage, inofanira kunge iine "chimiro chekudzivirira mvura" kana ichishandiswa munzvimbo ine mvura kana munzvimbo ine mvura.

5. Musiyano uripo pakati petambo isingapindi mvura netambo yakajairika
Musiyano uripo pakati petambo dzisingapindi mvura netambo dzakajairika ndewekuti tambo dzakajairika hadzigone kushandiswa mumvura. Tambo dzisingapindi mvura yeJHS rudzi rwetambo inochinjika yerabha, iyo inodziisa inodziisa rubber, uye tambo dzakajairika dzerabha, tambo dzisingapindi mvura yeJHS inowanzo shandiswa, asi iri mumvura kana kuti dzimwe dzinopfuura nemumvura. Tambo dzisingapindi mvura dzinowanzova nhatu, zhinji dzadzo dzinoshandiswa pakubatanidza pombi, mutengo wetambo dzisingapindi mvura uchadhura kupfuura tambo dzakajairika dzerabha, zvakaoma kusiyanisa kana dzisingapindi mvura kubva pakuonekwa, unofanirwa kubvunza mutengesi kuti uzive jira risingapindi mvura.

6. Musiyano uripo pakati petambo isingapindi mvura netambo isingapindi mvura
Tambo isingapindi mvura: inodzivirira mvura kuti isapinde mukati memuchina wetambo, uchishandisa chivakwa chisingapindi mvura nezvinhu.

Waya inovhara mvura: Muedzo uyu unobvumira mvura kupinda mukati mewaya, uye haubvumiri kupinda kusvika pakureba kwakatarwa pasi pemamiriro akatarwa. Waya inovhara mvura yakakamurwa kuita midziyo inovhara mvura nemidziyo inovhara mvura iri pakati pewaya.

Maumbirwo emuchina wekudzivirira mvura: kuwedzera hupfu hunovhara mvura neshinda inovhara mvura panguva yekusunga waya imwe chete, kana muchina wekudzivirira mvura uchipinda mumvura, hupfu hunovhara mvura kana shinda inovhara mvura inokura nemvura kudzivirira kupinda kwemvura, zvechokwadi, muchina wekudzivirira mvura une simba riri nani rekudzivirira mvura.

Maumbirwo ekudzivirira mvura emukati metambo: kana sheath yekunze yakuvara uye mvura ichipinda, tepi inovhara mvura inokura. Kana tepi inovhara mvura ikawedzera, inokurumidza kugadzira chikamu chinovhara mvura kudzivirira kupinda kwemvura. Kune tambo ine mativi matatu, zvakaoma kwazvo kuwana kuramba kwemvura kwemukati metambo, nekuti nzvimbo yepakati yepakati petambo ine mativi matatu yakakura uye haina kurongeka, kunyangwe kushandiswa kweblock yemvura kwakazadzwa, mhedzisiro yekuramba mvura haina kunaka, zvinokurudzirwa kuti core yega yega ibudiswe zvichienderana nechimiro chekudzivirira mvura chemukati mumwe chete, uye tambo yacho inoumbwa.
