Tambo dzisingapinde pamototaura kune tambo dzinogona kuchengetedza kushanda kwakachengeteka kweimwe nguva yenguva pasi pemamiriro ekupisa kwemurazvo.nyika yangu yenyika yenyika GB12666.6 (yakadai seIEC331) inoparadzanisa muedzo wekudzivirira moto mumagiredhi maviri, A uye B. Kupisa kwemoto wegiredhi A ndeye 950 ~ 1000 ℃, uye nguva inoramba ichipa moto ndeye 90min.Iyo tembiricha yemurazvo wegiredhi B ndeye 750 ~ 800 ℃, uye inoenderera nguva yekupa moto maminetsi makumi mapfumbamwe.min, mukati menguva yese yekuyedza, sampuli inofanirwa kumira neiyo yakatemerwa voltage kukosha inotsanangurwa nechigadzirwa.
Tambo dzinodzivirira moto dzinoshandiswa zvakanyanya muzvivakwa zvepamusoro-soro, njanji dzepasi pevhu, migwagwa yepasi pevhu, zviteshi zvemagetsi zvakakura, makambani akakosha eindasitiri nemigodhi nedzimwe nzvimbo dzine chekuita nekuchengetedza moto uye kurwisa moto uye kuponesa hupenyu, senge mitsara yekugovera magetsi uye mitsara yekudzora. yezvivakwa zvechimbichimbi semidziyo yekudzimisa moto uye marambi ekutungamira kwechimbichimbi.
Parizvino, waya dzakawanda dzisingadziviriri moto uye tambo kumba nekune dzimwe nyika dzinoshandisa magnesium oxide mineral insulated cables uye mica tepi-ronda-inodzivirira moto tambo;pakati pavo, chimiro che magnesium oxide mineral insulated cables inoratidzwa mumufananidzo.
Magnesium oxide mineral insulated tambo imhando yetambo isingadziviriri moto ine mashandiro arinani.Yakagadzirwa nemhangura core, copper sheath, uye magnesium oxide insulating zvinhu.Inonzi MI (minerl insulated cables) tambo kwenguva pfupi.Iyo tambo isingadziviriri tambo yetambo inoumbwa zvachose nezvinhu zvisingaite, nepo refractory layer yeakajairwa-anodzivirira moto tambo inoumbwa neinorganic zvinhu uye zvakajairika organic zvinhu.Naizvozvo, kuita kwekudzivirira moto kweMI tambo kuri nani pane kuya kwetambo dzinodzivirirwa nemoto uye hakuzokonzerese kukora nekuda kwekutsva nekuora.gasi.MI tambo dzine zvakanaka zvisingadziviriri moto uye dzinogona kushanda patembiricha yepamusoro ye250°C kwenguva yakareba.Panguva imwecheteyo, iwo zvakare anoputika-uchapupu, yakasimba corrosion resistance, hombe kutakura simba, radiation resistance, high mechanical simba, diki size, light weight, hupenyu hurefu, uye hutsi husina hutsi.Zvisinei, mutengo wacho unodhura, muitiro wacho wakaoma, uye kuvaka kwakaoma.Munzvimbo dzekudiridza oiri, zvakakosha zvemapuranga zvivakwa zveveruzhinji, nzvimbo dzekupisa kwepamusoro uye dzimwe nguva dzine hupamhi hwekudzivirirwa kwemoto uye hupfumi hunogamuchirika, rudzi urwu rwetambo ine yakanaka yekudzivirira moto inogona kushandiswa, asi inogona kungoshandiswa kuLow voltage fire resistant. cables.
Tambo isingadziviriri yakaputirwa nayomica tapeinoramba ichikuvadzwa nematepi akawanda e mica tepi kunze kwe conductor kudzivirira murazvo kubva pakupisa, nekudaro kurebesa nguva yakachengeteka yekuvhiya uye kuchengetedza tambo isina kuvharwa kweimwe nguva yenguva.
magnesium oxide
White amorphous powder.Haina hwema, isinganakidze uye isina chepfu.Iyo ine yakasimba yakakwira uye yakaderera tembiricha kuramba (yakakwirira tembiricha 2500 ℃, yakadzika tembiricha -270 ℃), corrosion resistance, insulation, yakanaka thermal conductivity uye optical properties, isina ruvara uye yakajeka crystal, melting point 2852 ℃.Magnesium oxide ine yakakwirira-inodzivirira moto uye inodzivirira zvivakwa, uye ine yakakwira kunyungudika.Inoshandiswa mukugadzira magnesium oxide mineral insulated tambo dzinodzivirira moto.
Mica tape
Mica is flaky inorganic mineral material, iyo inoratidzirwa nekudzivirira, kupisa kwekushisa kwepamusoro, kupenya, kugadzikana kwemuviri uye makemikari zvimiro, zvakanaka kupisa kupisa, elasticity, kuoma uye kusapisa, uye inobviswa kuita elastic zvinhu zvemashizha akajeka.
Mica tapeinogadzirwa neflake mica poda kuita mica bepa, inonamirwa kune girazi fiber jira rine anonamira.
Mucheka wegirazi wakanamirwa kune rumwe rutivi rwepepa remica unonzi "one-sided tape", uye iyo yakanamatira kumativi ose inonzi "double-sided tape".Munguva yekugadzira, zvimiro zvakati wandei zvinonamirwa pamwe chete, zvakaomeswa muchoto, zvakaputirwa, uye kupatsanurwa kuita matepi ehukuru hwakasiyana.
Mica tepi, inozivikanwawo sekuti moto-resistant mica tape, inogadzirwa ne (mica tepi muchina).Imhando yezvinhu zvinodzivirira moto zvisingadziviriri.Zvinoenderana nekushandiswa kwayo, inogona kukamurwa kuita: mica tepi yemotor uye mica tepi yetambo.Maererano nechimiro, yakakamurwa kuva: bhanhire remativi maviri, bhanhire-rimwe divi, bhanhire-mune-rimwe, bhanhire-mafirimu maviri, bhanhire rimwe chete-firimu, etc. Maererano ne mica, inogona kugoverwa kuva: synthetic. mica tepi, phlogopite mica tepi, uye muscovite tepi.
(1) Yakajairika tembiricha kuita: synthetic mica tepi ndiyo yakanyanya kunaka, inoteverwa ne muscovite tepi, uye phlogopite tepi haina kunaka.
(2) Insulation performance at high tembiricha: synthetic mica tepi ndiyo yakanyanya kunaka, inoteverwa nephlogopite mica tepi, uye muscovite tepi yakashata.
(3) Kumira kwekushisa kwepamusoro: Synthetic mica tepi, haina mvura yekristaro, inonyunguduka 1375 ° C, yakanyanya kupisa tembiricha kuramba, phlogopite inoburitsa mvura yekristaro pamusoro pe800 ° C, ichiteverwa nekupisa kwekushisa kwakanyanya, muscovite inoburitsa makristasi pa600. ° C Mvura, kushomeka kwekushisa kwakanyanya.
Ceramic refractory silicone rabha
Nekuda kwekuganhurirwa kwemamiriro ekuita, tambo isingadziviriri moto yakaputirwa nemica tepi inowanzokonzera kukanganisa mumajoini.Mushure mekubvisa, iyo mica tepi inova brittle uye nyore kudonha, zvichikonzera kushomeka kwekudzivirira moto.Insulation, zviri nyore kudonha kana ichizununguswa, saka zvakaoma kuve nechokwadi chekuchengetedza uye kutsetseka kutaurirana kwekutaurirana kwenguva refu uye simba kana moto.
Magnesia mineral insulated tambo dzinodzivirira moto dzinoda kupinza midziyo yakakosha, mutengo unodhura zvakanyanya, uye mari yekudyara yakakura;uyezve, iyo yekunze sheath yetambo iyi yese yemhangura, saka mutengo wechigadzirwa ichi zvakare unodhura chigadzirwa ichi;plus Rudzi urwu rwetambo rune zvakakosha zvinodiwa mukugadzira, kugadzirisa, kufambisa, kuisa mutsara, kuisirwa uye kushandisa, uye zvinonetsa kuita mukurumbira uye kuishandisa pamwero mukuru, kunyanya muzvivakwa zvevagari.
