Whatunga Whakapā - he aha te mea te reira? Āhuatanga catenary tereina, Wilkes i trolleybus ranei

Hanganga awhiowhio hiko tika tā whakapā o te whatunga. Ngā mihi ki tenei kai whakatinanahia te kohikohi supply ūnga o nāianei, e, i roto i te tahuri, te pei nga waka. He maha ngā momo o whatunga, engari tohu ratou he huinga o taura, whakatika, me te whakaū i ngā huānga whakarato mana i te teihanaroto hiko. Ano, Kei te whakamahia hoki te whatunga whakapā mō te tiaki o ngā pahoho, tae atu ngā whakawhiti me te rama whakato.

mōhiohio General e pā ana ki whatunga whakapā

Ko reira wahi o nga whakaurunga hangarau, i te mea wahi o te matatini o ara te uira me rori. Ko te whāinga matua o tenei hanganga ko ki te tuku mana tractive i te substation ki te rakau awhiowhio hiko. I roto i te tikanga ki te whakarite supply taputapu pūngao i teihanaroto maha whatunga whakapā e wehea ki te maha ngā wāhanga. Ko te kupu, i reira te mea he hanganga o wāhanga, ia o nei whangai e te pūwhāngai motuhake i te puna ngā.

Kei te whakamahia hoki wawahi ki te whakahaere i ngā mahi tiaki. Hei tauira, i roto i te take o te kino ki te raina te mana tuku poroa te i te kotahi anake pae. waea tinihanga, ki te tika, e taea te hono ki te substation mahi, e ka whakaiti downtime. I tua atu, i te whatunga whakapā o rerewē i insulators motuhake. Ko tenei whakatau e tika ana ki te meka e kia ofati i te arcing kōpeka i te wa o kaikohikohi nāianei haere te paninga taketake o te waea.

Ko te catenary pūrere

Networks o tenei momo ko te huinga o ngā wāhanga hanganga hiko. I roto i te ngā, he pūrere angamaheni o tenei hanganga ngā taura mana, te aukati motuhake, me te wahi tika motuhake me ngā hanganga tautoko. Ki te rā, tono ako, i roto i runga i te kōrero o nei, waea catenary me whare mamae he tukanga motuhake mō te galvanizing tūringiringi waiariki. Elements me ngawari maitai waro whai wāhi ki te maimoatanga paruru ki te whakapiki ake i te kaha me te mauroa kōrero.

Āhuatanga rangi catenary

whatunga Air te tino noa tika ki te wāhi-ora me ngā rārangi hiko pai atu. Heoi, i reira he drawbacks o te pūrere taua, e kua whakahuatia i roto i utu teitei mō te tāutanga, me te tiaki. Ko te kupu, ko te whatunga whakapā rauata ngā te whakatārewatanga taura, whare, waea, pere ki pekanga, me te insulators.

E iti ana te matua hanganga o whatunga o tenei momo āhuatanga ki te tukanga o te noho. whakairihia Communication i runga i te tautoko motuhake. I roto i tenei tāutanga i waenganui i ngā taea te tohua sagging o waea. Whakakore tenei koha e kore e taea, engari ka taea e tona aroaro meinga kino ki rārangi mana. Hei tauira, ki te taea te tautoko whatunga whakapā sagging kaha, ka neke haere te kaikohi taura i roto i te whakatārewatanga whenua e taea ngaro pa ki to ratou aho.

whatunga Whakapā o rerewē

I roto i tenei take e korero tatou e pā ana ki te putanga matarohia o te whatunga whakapā. Railways reira mahi i te pukapuka nui o ngā rauemi mō ngā tereina Electrification. whakaputaina te waea mo taua take e i pakeke parahi -hiko rohe ripeka-motu unu o 150 mm ^2. Ki te whakaaro ki nga mea timatanga tautoko, ngā te whatunga tereina whakapā i te raima whakarewa ranei tāuta, e kore neke atu i 310 cm Heoi, i reira he okotahi tona tiketike e taea tae 15 m wā o te huarahi tino te tuaka ki nga taha o waho o nga tautoko i runga i nga teihana me Tīpae e - .. Hei tauira, i roto i hangarau mamae taea te wā whakaiti ki 245 cm tikanga tiaki i nga waea o te momo i whakamahia e tikanga -. wehenga ki ngā wāhanga motuhake, te whakamahi o insulators me fakahū kūpapa.

whatunga trolleybus Whakapā

Whakaritea ki te whakakorekore kaupapa waka trolley kore e amo i te hononga hiko tonu ki te mata. nui haere hoki ngā whakaritenga mō te huri mai, hua i roto i ngā rerekētanga i roto i te whakahaere o te Electrification hanganga. Ēnei rerekētanga ka tāutuhia i te āhuatanga matua o te hiko mō ngā pahi trolley - te aroaro o ngā rārangi e rua-waeahia. I tua atu, i whakaritea i ia waea te ki wā iti, me te whakaratohia ki te mātao pono. Ka rite ki te hua, riro uaua te whatunga me te whakapā i runga i te tika wāhanga, peka, a i roto i ngā rohe me te pekanga. Ka taea te pēnei te āhuatanga motuhake me te whakamahi wawahi whānui ki te insulators tēnā. Otiia i roto i tenei take, i te anga e kore anake tiaki te waea i whakapā ia atu, engari ano ki te tiaki i te rauemi i te pekanga. I tua atu, e kore e whakaaetia te hanganga o whatunga trolleybus ki te whakamahi i te kopere tango me pantograph.

whatunga Whakapā o Ruxmaniben

Nga whatunga Wilkes i, waea whakapā, e te tikanga e whakamahia ana parahi, me ngā āhuatanga ōrite mō ngā alloys. Ano, e kore e aukati i te reira i te whakamahi o conductors maitai-konumohe. whakamana Conjugation o ngā wāhanga ki te tiketike rerekē o te whakatārewatanga te ki te waea rītaha ki te faatura ki te kōtaha wä roa o te ara. Ko te kupu kia rerekē te ine i te 20 ki te 40% i runga i te matatini me te tikanga o te gasket wahi raina rānei. I runga i nga straights te whatunga Wilkes i o ngā hoapā kei roto i te tikanga kōpekapeka. I roto i tenei kōpekapeka taahiraa - ahakoa o te whakatārewatanga - e kore neke atu i wha maro. Me kï hoki me te uara o taura whakapā whakarerea i te tuaka susceptor - tenei uara ko te tikanga e kore e rahi ake i te 25 cm.

mutunga

Ahakoa te whanaketanga hangarau o te Electrification, whatunga whakapā i roto i nui rerekē constructional pupuri i te taputapu tikanga. Huringa i roto i ngā o te whakapai ake o ngā tawhā hangarau, me te whakahaere pā anake etahi āhuatanga o te kōrero tono. I roto i ngā, kei te piki tukua te kupenga whakapā o rerewē ki wāhanga e i haere galvanizing tūringiringi waiariki. Atu pūtake tukatuka huānga, o te akoranga, whakapai ake te tika me te mauroa o te rārangi, engari whai wāhi te whakapai ake hangarau tuwhena ki te tohu iti. Ko te taua pā ki te Wilkes i, a tōneke whatunga hiko, i roto i nei, Heoi, tata tino pai ake te whakatika pūrere me nga wahi kaha ngā iri hanganga.
