1. Te kaupapa me ngā āhua owhakawhititiaki
a. Te kaupapa o te tiaki i te whakawhiti hiko
Ko te kaupapa matua o te tiaki i te whakawhiti hiko ko te whakarite kia pai te āhua o roto, o waho hoki o te whakawhiti hiko me ngā taputapu. ngā wāhangakia pai te āhua, kia "tau mō te kaupapa" ā, ka taea te mahi haumaru i ngā wā katoa. He mea nui anō hoki te pupuri i tētahi tuhinga hītori mō te āhua o te whakawhiti hiko.
b. Ngā puka tiaki mō te whakawhiti hiko
He maha ngā mahi tiaki auau e hiahiatia ana mō ngā whakawhiti hiko, tae atu ki te ine me te whakamātautau i ngā tawhā rerekē o te whakawhiti hiko. E rua ngā momo matua o te tiaki i te whakawhiti hiko. Ka whakahaerehia e mātou tētahi rōpū i ia wā (e kiia ana ko te tiaki ārai) me te tuarua i runga i te kaupapa motuhake (arā, i runga i te tono).
2. Te Tirotiro Tiaki ā-Marama mō te Whakawhitiwhiti
– Me tirotirohia te taumata hinu i roto i te taupoki hinu i ia marama, kia kore ai e heke ki raro i te taumata kua whakaritea, ā, kia kore ai e kino.
- Kia ma tonu ngā pūaha manawa i roto i te ngongo manawa o te silica gel kia tika ai te mahi manawa.
- Ki te mea ko tāuwhakawhiti hikoMena he rūma whakakī hinu, kia tika te whakakī o te hinu.
Ki te tika, ka whakakīia te hinu ki roto i te pūwero ki te taumata tika. Ka mahia te whakakī hinu i roto i te āhua kati.
3. Te Tiaki me te Tirotiro i ia Rā
– Pānuihia te MOG (Mita Hinu Aukume) o te tāke matua me te tāke rokiroki.
- Te tae o te tiēre silica i roto i te manawa.
- Ka turuturu te hinu mai i ngā wāhi katoa o te whakawhiti hiko.
Mēnā kāore i te pai te taumata hinu i roto i te MOG, me whakakī te hinu ki roto i te whakawhiti hiko, ā, me tirotiro te tāke katoa o te whakawhiti hiko mō ngā turuturu hinu. Mēnā ka kitea he turuturu hinu, me mahi i te mahi e tika ana hei hiri i te turuturu. Mēnā ka paku māwhero te kiripaka, me whakakapi.
4. Te kaupapa tiaki ā-tau taketake o te whakawhiti hiko
– Mā te mahi aunoa, mamao, me te mahi ā-ringa o te pūnaha whakamatao ka honoa ngā papu hinu, ngā pā hau, me ētahi atu taputapu ki te pūnaha whakamatao o te whakawhiti hiko me te ara iahiko whakahaere. Ka tirotirohia ēnei i roto i te wā kotahi tau. Mēnā ka hē te mahi, tirotirohia te ara iahiko whakahaere me te āhua o te papu me te pā.
- Me horoi ngā pū whakapū whakawhiti hiko katoa ki te kakahu miro ngohengohe i ia tau. I te wā e horoia ana te pū, me tirotiro mēnā he pakaru.
- Ka tirohia te āhua o te hinu o te OLTC i ia tau. Nō reira, ka tangohia te tauira hinu mai i te takirere waikeri o te tāke wehewehe, ā, ka whakamatautauria tēnei tauira hinu kua kohia mō te kaha hiko-kore (BDV) me te haumākū (PPM). Mena he iti te BDV, ā, he teitei ake te PPM mō te makuku i te uara kua tūtohutia, me whakakapi, me tātari rānei te hinu i roto i te OLTC.
- Te tirotiro ā-mīhini o Buchholzngā whakawhitikia whakahaerehia i ia tau.
- Me horoi ngā ipu katoa mai i roto i te iti rawa kotahi i te tau. Me tirotirohia ngā rama katoa, ngā whakamahana rūma rānei, kia kitea ai mēnā kei te tika te mahi. Ki te kore, me mahi koe i ngā mahi tiaki. Me tirotirohia ngā hononga pūrua katoa o te waea whakahaere me te waea whakawhiti, ā, me whakau ake i te iti rawa kotahi i te tau.
- Me horoi ngā whakawhiti, ngā whakaoho, me ngā pana whakahaere katoa me ō rātou ara iahiko, i roto i ngā panera R&C (Paewhiri Mana me ngā Whakawhiti) me te RTCC (Paewhiri Mana Huringa Tap Mamao), ki te horoi tika i ngā matū.
- Ngā pōke mō te OTI, te WTI (Tohu pāmahana hinu me te tohu pāmahana koiri) kei runga i te taupoki o runga o te whakawhiti hiko hei tirotiro, me te mea e hiahiatia ana te hinu.
- Me tirotirohia te mahi tika o te Pūrere Tuku Pēhanga me te whakawhiti Buchholz i ia tau. Nō reira, ko ngā hononga pakaru me ngā hononga whakaoho o ngā pūrere i runga ake nei ka whakapotoa ki tētahi wahi waea iti, ā, me tirotiro mēnā kei te tika te mahi a ngā whakawhiti e pā ana ki te papatohu mana mamao.
- Me tirotirohia te ātete whakamarumaru me te taupū polarity o te whakawhiti hiko mā te whakamahi i te megger e whakahaerehia ana me te pākahiko 5 kV.
- Me ine i te ātete o te hononga whenua me te rizer i ia tau mā te whakamahi i tētahi rawhi i runga i te mita ātete whenua.
- Me mahi te tātaritanga DGA, te tātaritanga hau rewa rānei o te hinu whakawhiti hiko i ia tau mō ngā whakawhiti hiko 132 kV, kotahi i roto i ngā tau e rua mō ngā whakawhiti hiko kei raro iho i te 132 kV, mō ngā tau e rua mō ngā whakawhiti hiko kei runga i te whakawhiti hiko 132 kV.
Ngā mahi hei mahi i ia rua tau:
Me mahi te whakatikatika i te OTI me te WTI i ia rua tau.
Tan & delta; Me ine anō hoki ngā pū o te whakawhiti hiko i ia rua tau.
5. Te tiaki i te whakawhiti i ia hawhe tau
Me whakamātau i tō whakawhiti hiko i ia ono marama mō te IFT, te DDA, te ira mura, te nui o te paru, te waikawa, te nui o te wai, te kaha dielectric, me te ātete ki te hinu whakawhiti.
6. Te tiaki iWhakawhiti Auaha
He wāhanga nui ngā whakawhiti hiko o ngā taputapu katoa e tāutahia ana ki tētahi teihana whakawhiti hiko hei tiaki me te ine i te hiko.
Ko te kaha o te whakamarumaru o te CT Me tirotiro i ia tau. I roto i te tukanga ine i te ātete ārai, me mahara kia rua ngā taumata ārai i roto i ngā whakawhiti iahiko. He teitei te taumata ārai o te CT tuatahi, nā te mea me tu atu ki te ngaohiko pūnaha. Engari he iti te taumata ārai o ngā CT tuarua i te nuinga o te wā, arā, 1.1 kV. Nō reira, ka inehia te tuatahi ki te tuarua me te tuatahi ki te whenua o ngā whakawhiti iahiko ki ngā meka 2.5, 5 kV rānei. Engari kāore e taea te whakamahi i tēnei meka ngaohiko teitei mō ngā inenga tuarua nā te mea he iti te taumata ārai mai i te tirohanga ōhanga o te hoahoa. Nō reira, ka inehia te ārai tuarua ki te meka 500 V. Nō reira, ka inehia te pito tuatahi ki te whenua, te pito tuatahi ki te matua ine tuarua, me te pito tuatahi ki te matua tiaki tuarua ki ngā meka 2.5, 5 kV rānei.
Me mahi te matawai tirohanga wera o ngā pito matua me te tihi o te CT ora i te iti rawa kotahi i te tau. Ka taea te mahi i tēnei matawai mā te āwhina o te Kāmera Tirotiro Wera Whero.
Me tirotiro, me horoi, me whakakaha hoki ngā hononga tuarua CT katoa i roto i te pouaka tuarua CT me te pouaka hononga CT i ia tau kia iti rawa ai te ara ātete tuarua CT. Me whakarite hoki kia tika te horoinga o te pouaka hononga CT.
Ngā Hua o te Whakawhiti MBT
7. Te tiaki ā-tau owhakawhiti hikongā whakawhiti ngaohiko s, capacitor rānei
Me horoi te taupoki porcelain ki te kākahu miro.
Ka tirohia te huihuinga āputa mura i ia tau. Tangohia te wāhanga nekeneke o te āputa mura i te wā e huihui ana, horoia te hiko o te pūhiko ki te pepa kirikiri, ka whakahokia ki tōna tūranga.
Me tirotirohia te pūwāhi whenua auau teitei i ia tau, mēnā kāore te raruraru e whakamahia mō te PLCC.
Ka whakamahia ngā kāmera tirohanga wera hei tirotiro i ngā wāhi wera i roto i ngā puranga pūnga iahiko kia pai ai te mahi whakatikatika.
Ko ngā hononga pūrua o te pouaka hononga PT he mea hanga ki ngā hononga whenua e whakamatautauria ana mō te piri kotahi i te tau. Haunga tēnā, me horoi pai hoki te pouaka hononga PT kotahi i te tau.
Me tirotiro hoki te āhua o ngā hononga gasket katoa, ā, me whakakapi mēnā ka kitea he hiri kua pakaru.
