Pēhea te Whakapai ake i te Haumātauranga Hiko mā te Kaitiaki Ara hiko Māwheraumati

Ko te VCB (Vacuum Circuit Breaker) mātāmira he wāhanga matua mō te haumaru me te tiaki i te tukatuka hiko ki roto i ngā pūnaha hiko mātāmira (10kV - 35kV). He pai ake ia i ngā whakamutu tawhito e whakamahi ana i te hinu, inihini rānei, nā te mea ko te VCB e whakamahi ana i tētahi kamupene kaukau hei whakamutu i ngā awelika hiko, ka wehe anuanu te wāhanga kino o te whatitoka. He tino āwhina ia i ngā tikanga uaua pērā i ngā whatitoka hiko taone, ngā tohunga hanga, me ngā takotoranga hokohoko. Ko GPSwitchgear te kaiārahi ki te whakapai ake i te hoahoa VCB mātāmira mō te haumaru pai ake, me ōna whakamahinga i te ao whai pūtake. Kei raro nei ētahi ara e whakapai ai te VCB mātāmira i te haumaru hiko.

Te Pokapū a te VCB Mātāmira ki te Whakamātau, Whakapaipai, me te Aukati i ngā Tūmataiti Arca

I ngā pūnaha mātātoko, ko ngā araki hiko te tīmatanga o ngā mōrearea kino. Ki te whakamārama ake, he 20,000 nekeneke Celsius te wera e hāngai ai, ka taea te huruhuru i ngā parahi, te whara i ngā ārai-wera, me te āhua anō hoki ki ngā ahi me ngā epurapora. Ko te VCB mātātoko hiko e kuhu ana i ngā āhuatanga pai rawa atu o ia ao, ina koa ngā īnga hokiwhi araki o te kaukau. Ina hea pea te take, pērā i te hiko-poto, ka wehe tika ngā hononga o te VCB mātātoko hiko ki roto i te kamupene kaukau. Nō te taiao kaukau, ka ngaro te hanga i ngā hau ionihia (e mau ana ngā araki ki ētahi atu taputapu motini), ka pakaru te araki i roto i te 1 ki te 2 mātā (neke atu rānei i te 0.04 hēkona mō tētahi pūnaha 50Hz). He tino tere ake tēnei i ngā taputapu motini hinu, āhuarangi rānei, ā, ka iti ake te wā e noho ana te araki, ka iti ake hoki te mōrearea o te ahi me te whara. Hei tauira, i tētahi pūnaha tukutuku hiko mātātoko 10kV, ka whakauru te hiko-poto kawhe ki te VCB mātātoko hiko kia tango i te hiko, ka pakaru te araki tūwae tonu, ā, ka aukati i te taraweti ki ngā taputapu huri noa.

Ko te VCB waewae hiko o GPSwitchgear e whai ana i ngā tūru kaukau koukou koukou hoki he 10⁻⁶ Pa, e pai ake ai te haumaru me te mahi pūpahi pūhara tūmau mō te 20 tau nekehanga rānei.

Te Mahi Tūturu o te VCB Hiko Waewae Kaha ki te Atakina i ngā Mōrearea Rere  

Ko te pakaru o te whakamātai i ngā punaha mīhini he take mō ngā rere tūpono, ngā hapa taputapu, me ngā pānga hiko ki ngā kaimahi. Ko te VCB mīhini e horoi ana ki te whakamātai i ngā hoahoa e rua: tuatahi, ko te hanganga o te kamupene paraihe: nā te mea kei roto he kamupene paraihe, ka mahi hei kamupene whakamātai. Ka aukati te paraihe i te rere o te hiko i waenganui i ngā hononga ki te volatike e whakaae ana te inenga, nā te mea he nui ake te kaha whakamātai i te paraihe i te hau, i te hinu rānei. Ko te āhuatanga tuarua ko te VCB mīhini e horoi ana i te rino epoksi, i ngā matēriera rino rānei mō te takotoranga o te kamupene paraihe, he iti te painga ki te waimā, ki te puehu, ki te korairi hoki. Nō reira ka aukatia te pakaru o te whakamātai mā te waimā. Kāore he hinu, he kātahi rānei te VCB mīhini e rere ai, nā reira e haumaru ana mō ngā wāhi o waho, o roto hoki (e kore nei e rere te hinu i ngā taputapu tapawhā, ā, ka pakaru hoki te whakamātai). Hei tauira, ko ngā rohe takutai haumaru i ngā wāhi ahumahi nui he wāhi pai mō ngā VCB nā te mea kāore te waimā i te rangi, te upoko maroke rānei e here ana i te takotoranga whakamātai, i te kamupene paraihe hoki o te VCB. Ka taea e te VCB te mahi tonu, te aukati hoki i ngā hapa rere volatike. Me whai ngā VCB mīhini katoa i ngā whakamātautau whakamātai AC me ngā whakamātautau rere paku kia taea ai te whai mātai i ngā tīkanga whakamātai, i ngā tīkanga haumaru ā-ao hoki.

Whakaaetia e te VCB Mātua Tension te Tiaki Kāwai mā te Whakatētē i te Aha o te Maru

Ko ngā hapa ki ngā pūnaha mātātoko kikoheke he tōpuni-tau, he tino-kī, me ngā wae o ngā waea whenua, ā, e taea ana e ēnei te whakaputangia i ngā turupairei me ētahi atu taputapu tino utu. Mā ngā turupairei waea hapa kikoheke utu nui, ka taea e ngā VCB kikoheke te tautohe i ngā waea hapa me te whakatēa i ngā waea hapa nā te mea kei a rātou ngā pūkete tiaki matatau huinga-honohono, ā, ka taea e rātou te mahi tahi me ngā rerehua tiaki āhuatanga. Ka tātari ngā rerehua i ngā pūnaha hiko ki te wā nei, ā, ka whakawhitinga kōrero ki te VCB kikoheke ina kitea e rātou he hapa, ka whakauruhia tūmatanui te aronga whakatēa i te waea hapa e te VCB. Heoi anō, kāore ngā VCB e whakatēa i te waea e neke ake ana i te ine ake e māmā ai te taputapu kikoheke. Hei tauira, ko ngā VCB kikoheke mō ngā pūnaha hiko 20kV e taea ana e rātou te whakatēa i ngā waea hapa ki raro i te 20kA, ā, ka aukati i te waea tino nui e rere ana ia ngā turupairei me ngā kawhe. E tiaki ana tēnei i te pūnaha mai i te hapa o te takotoranga me te hapa ā-tinana i te wā o te tino-kī. Hei tauira, ka whakahohe ngā tikanga tiaki hapa e rerekē ana i te pūnaha pātai 20kV i te pūnaha hiko o tētahi kominiti hokohoko hei tiaki i te turupairei matua.

Kei te tuku a GPSwitchgear i ngā VCB māmā e whakamahi ana i tētahi arataki matūpōkai, i tētahi arataki pēhanga rānei hei whakarite kia tere te wehe atu o ngā hononga, ka whakaritea hoki te whakatārewa i te auwhainga haruru i roto i te wā haumaru tīmatia.

Ko ngā Tūponotanga Tiaki i ngā VCB Māmā he Haumaru, nā te Iti o ngā Mahi Tiaki e Hiahiatia ana

Ko te VCB waewaeātata he iti ake te mahi nā te iti ake o ana herekore e hiahiatia ana. Ko ētahi atu tapatoru pērā i ngā tapatoru ara-oil e hiahiatia ana ngā mahi herekore maha pērā i te whakakapi i te hinu, te horoi i ngā hononga, te tūhuratanga i te pihanga hau, me ētahi atu anō. Ka piki ake ngā utu whakahaere e āhua ai ēnei mahi, ā, ka whakaputangia ngā kaimahi herekore ki te mōrearea o te pānga ki te hiko. Ko te VCB e mahi ana mā te kaupapa o te tiaki i ngā wāhanga. E roa ana ngā wāhanga o tana kamara paraihe, me ngā wāhanga hononga—neke atu i te 10,000—i mua i te hiahiatia ko te herekore tuatahi. Ka taea te herekore i ngā rautaki whakahaere, me te whakapakari i ngā tikanga āwhina (ara whakahaere) kāore e hiahiatia te whakawātea i te kamara hiko-kaha, nō reira ka wehea atu ngā mahi herekore e pā ana ki te hiko-kaha. Tēnā ka iti ake te pānga o ngā kaimahi ki te hiko-kaha, ā, ka wehea atu ngā mahi pērā i te herekore i ngā hononga parauri. Ka tukuna ēnei wāhere herekore ki ngā herekore e mahi ana ki ngā VCB waewaeātata kei ngā wāhi tāwhai. Mā te whakarite i te herekore ā-tau o ngā tapatoru ara-hinu, ko ngā VCB waewaeātata kei ngā wāhi tāwhai, e 3 ki te 5 tau ngā wāhere herekore. Nō reira ka iti noa te mahi herekore i runga i te tapatoru. Ka pupurihia ēnei mōrearea ki te VCB āhuahua waewaeātata a GPSwitchgear. Ko tēnei hoahoa e taea ai te herekore i ngā wāhanga āwhina kāore e pā ki te kamara paraihe. Nō reira ka iti ake te mōrearea o te herekore kino, me te pānga o te kaimahi.

Ka tautokona e te VCB Mātara Tōpūtanga ngā māngai herehere kia kore ai ngā hapa whakahaere

Ko ngā punaha mātātoko he iti noa te āhua o ngā take mōrearea, tae atu ki ngā take mātātoko, mō te whakamahinga hē, hei tauira, te kapi i te piko i runga i tētahi raina hapa, i te wā e kore e tika ana te whakatuwheratanga i te piko i te wā e kore e whakaaetia ana te utu. Ko te VCB he tikanga whakauru ki roto hei whakaiti i te āhua o te whakamahinga hē. Ki te timata, ko te VCB he hononga mekanihiko me te kaiwehe. Anake ka taea te kapi i te VCB i te wā e tu ana te kaiwehe, ka aukati i te kapinga i tētahi ara weto. Ko te VCB hoki he hononga hiko me te punaha whakahaere. Anake ka taea te whakamahi i te VCB e ngā kaimahi whakaaetia me te waehere urupare tika, i te rūri whakahaere rānei, ka aukati i te tuwheratanga, te kapitanga hore e whakaaetia ana. Ko te VCB hoki he punaha hono āhua. Mēnā kei te rere te kamara paraihe o te VCB, ka kitea e ngā kaiwhakaaro tokiwhenua te hapa o te araki, ka hāpotohia te piko, ka aukati i tana mahi i te wā o te whakakaha i te wāhi. He tauira mataara kei te rūma taputapu whakamarumaru mātātoko, mēnā ka ngana tētahi kaimahi ki te kapi i te piko raina hapa ki te VCB, ka aukati te aukati mekanihiko i te kino ki te taputapu mā te aukati i te kaimahi e kapi ana i te piko.

Kua riro e te VCB māke koretake a GPSwitchgear ngā rāpū katoa, ka taea e te whakahaere te whai me te whakatau i ngā mahi, ka iti ake te mōrearea o ngā hapa whakahaere āhuatanga, āhuareka rānei.
