Tambo dzepakati nepakati dzine voltage pakati pe6 kV ne33kV.Iwo anonyanya kugadzirwa sechikamu chekugadzira magetsi uye kugovera network kune akawanda maapplication akadai sezvishandiso, petrochemical, chekufambisa, kurapwa kwemvura yetsvina, kugadzira chikafu, misika yekutengesa uye maindasitiri.
Kazhinji, iwo anonyanya kushandiswa mumasisitimu ane voltage renji kusvika ku36kV uye anoita basa rakakosha mukugadzira magetsi uye kugovera network.
01.Standard
Nekukura kuri kuita kudiwa kwepasirese kwepakati magetsi tambo, kuenderana neindasitiri zviyero zviri kuramba zvichinyanya kukosha.
Iyo inonyanya kukosha maitiro epakati voltage cables ndeaya:
IEC 60502-2: Iyo inonyanya kushandiswa yepakati-voltage tambo munyika, ine yakatemerwa voltage kusvika ku36 kV, yakakura dhizaini yekugadzira uye kuyedzwa, kusanganisira imwechete-core tambo uye akawanda-core tambo;tambo dzezvombo uye tambo dzisina zvombo, marudzi maviri Nhumbi dzezvombo "bhandi uye tambo yezvombo" inosanganiswa.
IEC/ EN 60754: Yakagadzirirwa kuongorora zviri mukati mehalogen asidhi magasi, uye ine chinangwa chekuona iyo asidhi magasi anoburitswa kana insulation, sheathing, nezvimwe zvinhu zviri pamoto.
IEC / EN 60332 kuyerwa kwekupararira kwemurazvo mukati mehurefu hwetambo kana pakaitika moto.
EN 61034 IEC / EN 61034: inotsanangura bvunzo yekuona hutsi density yekupisa tambo pasi pemamiriro akatarwa.
BS 6622: Inovhara tambo dzeakatemerwa voltages kusvika ku36 kV.Inovhara chiyero chekugadzira uye kuyedzwa, kusanganisira imwechete musimboti uye akawanda epakati tambo;armored tambo chete, waya armored mhando chete uye PVC sheathed tambo.
- BS 7835: Inovhara tambo dzeakatemerwa voltages kusvika ku36 kV.Inovhara chiyero chekugadzira uye kuyedzwa, kusanganisira imwe-musimboti, akawanda-musimboti tambo, tambo dzehondo chete, dzakashongedzerwa chete, dzakaderera-utsi halogen-isina tambo.
BS 7870: nhevedzano yemazinga akanyanya kukosha kune yakaderera uye yepakati voltage polymer insulated tambo dzekushandisa nekugadzira magetsi nemakambani ekuparadzira.
02.Structure uye zvinhu
Medium voltage cablemagadzirirwo anogona kuuya muhukuru hwakasiyana uye mhando.Chimiro chacho chakanyanya kuoma kupfuura iyo ye-low-voltage cables.
Musiyano uripo pakati pepakati voltage tambo uye low voltage tambo hausi chete magadzirirwo etambo, asiwo kubva pakugadzira maitiro uye zvigadzirwa.
Mune epakati voltage tambo, iyo insulation maitiro akasiyana chaizvo neakaderera voltage tambo, kutaura zvazviri:
- Iyo yepakati voltage tambo ine matatu akaturikidzana pachinzvimbo cheimwe layer: conductor shielding layer, insulating material, insulating shielding layer.
-Iyo nzira yekudzivirira yepakati voltages inowanikwa nekushandisa CCV mitsara pachinzvimbo cheyakajairwa yakachinjika extruder, sezvazvakaita kune yakaderera voltage tambo.
-Kunyangwe kana iyo insulation iine zita rakafanana neiyo yakaderera voltage tambo (semuenzaniso XLPE), iyo mbishi pachayo yakasiyana kuti ive nechokwadi chekuchenesa kwakachena.Colour masterbatches yelow-voltage cables haabvumidzwe kuti core identification.
- Metallic skrini inowanzoshandiswa mukuvaka tambo dzepakati voltage yeakadzika voltage tambo dzakatsaurirwa kune chaiwo maapplication.
03.Muedzo
Zvigadzirwa zvepakati-voltage tambo dzinoda bvunzo dzakadzama dzemhando yekuongorora zvikamu zvega uye tambo yese zvichienderana nemvumo yese yezvigadzirwa zvetambo.Medium voltage cables anoedzwa kune avomagetsi, mechanical, zvinhu, makemikari uye moto kudzivirira mabasa.
Electric
Partial Discharge Test - Yakagadzirirwa kuona kuvepo, ukuru, uye kutarisa kana hukuru hwekubuda hunodarika kukosha kwakatarwa kune chaiyo voltage.
Thermal Cycling Test - Yakagadzirwa kuti iongorore kuti chigadzirwa chetambo chinopindura sei kune inogara ichichinja tembiricha mubasa.
Impulse Voltage Test - yakagadzirirwa kuongorora kana chigadzirwa chetambo chinogona kumira nekuwedzera kwekurova kwemheni.
Voltage Test 4 Maawa - Tevedzera kutevedzana kwebvunzo kumusoro kuti usimbise kutendeseka kwemagetsi kwetambo.
Mechanical
Shrinkage kuyedzwa - yakagadzirirwa kuwana nzwisiso mukuita kwezvinhu, kana mhedzisiro pane zvimwe zvikamu mukuvakwa kwetambo.
Abrasion Test - Nyanga dzesimbi dzakapfava dzinomanikidzirwa kutakurwa seyakajairwa dzobva dzadhonzerwa dzakachinjika patambo nenzira mbiri dzakapesana kusvika chinhambwe che600mm.
Heat Set Muedzo - Yakagadzirwa kuti iongorore kana paine yakakwana crosslinking mune izvo zvinyorwa.
Chemical
Corrosive uye Acid Gasi - Yakagadzirirwa kuyera magasi anoburitswa sekupisa kwetambo samples, kutevedzera mamiriro emoto, uye kuongorora zvese zvisiri zvesimbi zvikamu.
Moto
Flame Spread Test - Yakagadzirirwa kuongorora uye kunzwisisa tambo yekushanda nekuyera kupararira kwemurazvo kuburikidza nehurefu hwetambo.
Muedzo weSmoke Emission - Yakagadzirwa kuti ive nechokwadi chekuti chiutsi chinogadzirwa hachikonzeri kuderera kwekutapurirana kwechiedza pane zvakatsanangurwa zvakakosha.
04.Common malfunctions
Matambo asina kunaka anowedzera mitengo yekutadza uye anoisa magetsi emushandisi wekupedzisira panjodzi.
Zvikonzero zvikuru zveizvi kuchembera kusati kwasvika kweiyo tambo zvigadzirwa, husina kunaka hwaro hwemajoini kana tambo yekumisa masisitimu, zvichikonzera kuderera kwekuvimbika kana kushanda zvakanaka.
Semuenzaniso, kuburitswa kwechikamu chekuburitsa simba ndiyo yekutanga kukundikana, sezvo ichipa humbowo hwekuti tambo inotanga kushata, izvo zvinozoita kuti kukundikana uye kukundikana, kuteverwa nekudzima kwemagetsi.
Kuchembera kwetambo kunowanzotanga nekukanganisa kuvharwa kwetambo nekudzikisira magetsi, inova chiratidzo chikuru chehurema hunosanganisira hunyoro kana homwe dzemhepo, miti yemvura, miti yemagetsi, uye mamwe matambudziko.Mukuwedzera, kupatsanurwa sheaths kunogona kukanganiswa nekuchembera, kuwedzera njodzi yekuita kana ngura, izvo zvinogona kukonzera matambudziko gare gare mubasa.
Kusarudza tambo yemhando yepamusoro yakaedzwa zvakakwana inowedzera hupenyu hwayo, inofanotaura kugadzirisa kana kutsiva nguva, uye inodzivirira kukanganisa kusingakoshi.
05.Type yekuongorora uye kubvumirwa kwechigadzirwa
Kuyedzwa kwefomu kunobatsira nekuti inosimbisa kuti imwe sampu yetambo inoenderana neimwe mwero pane imwe nguva.
BASEC kubvumidzwa kwechigadzirwa kunosanganisira kuomesera kwedhipatimendi rekutarisa kuburikidza neanogara achiongorora maitiro ekugadzira, manejimendi masisitimu uye yakaoma tambo yekuyedza sampuli.
Muchirongwa chemvumo yechigadzirwa, akawanda masampuli anoyedzwa zvichienderana netambo kana huwandu huri kuongororwa.
Iyo yakaomesesa BASEC certification process inovimbisa mushandisi wekupedzisira kuti tambo dzakagadzirwa kune dzinogamuchirwa indasitiri zviyero, dzinogadzirwa kusvika padanho repamusoro uye dziri kuenderera mberi nekushanda, zvichideredza zvakanyanya njodzi yekutadza.
