PT uye CT muTransformers: Iwo Unsung Magamba eVoltage uye Azvino

PT uye CT muTransformers: Iwo Unsung Magamba eVoltage uye Azvino

Kana zvasvika kune ma transformer,PT(Inogona Transformer) uyeCT(Yazvino Transformer) yakafanana neiyo ine simba duo yenyika yemagetsi-Batman naRobin. Ivo vanogona kusagadzika nzvimbo senge transformer pachayo, asi maviri aya anoshanda kuseri kwezviitiko kuona kuti zvese zvinofamba zvakachengeteka uye nemazvo. Ngatinyure mumashandisiro avanoita mashiripiti avo mumaseti akasiyana etransformer.

PT: The Voltage Whisperer

TheInogona Kushandura (PT)ndiye wako-kune mukomana wekudzika pasi yakakwira voltage kusvika padanho rinogoneka. Fungidzira kuti uri kutarisana neinotyisa 33 kV (kana kutopfuura) musimba rako remagetsi-ine njodzi uye kwete chimwe chinhu chaungade kuyera zvakananga. Ndipo panouya PT. Inoshandura iwo mavhiri ekusimudza bvudzi kuita chimwe chinhu mamita ako uye relays anogona kubata pasina kutyora dikita, kazhinji achidzika pasi kune chimwe chinhu senge 110 V kana 120 V.

Saka, unowana kupi PTs mukuita?

• High-voltage transmission transformers: Idzi ndidzo pfuti hombe dzegedhi remagetsi, dzinobata magetsi chero kupi kubva pa110 kV kusvika 765 kV. PTs pano ita shuwa kuti unogona kutarisa uye kuyera voltage zvakachengeteka kubva kure.
• Substation transformers: PTs inoshanda muzviteshi kuti itarise uye kudzora mazinga emagetsi isati yagovaniswa kune vatengi veindasitiri kana vanogara.
• Dziviriro uye metering transformers: Mune masisitimu umo kutariswa kwemagetsi kwakakosha pakuchengetedza uye kubhadhara, PTs inopinda mukati kuti ipe kuverenga kwakaringana kwemagetsi kumakamuri ekudzora, relay, uye midziyo yekudzivirira.

PT yakaita semuturikiri akadzikama, akaunganidzwa pakonzati yemagetsi ine ruzha, achitora manotsi e110 kV anotsemura nzeve achiashandura kuita ruzha runyoro rwunogona kubata mudziyo wako.

CT: Iyezvino Tamer

Zvino, ngatitaure nezveShanduko Yazvino (CT), mudzidzisi wega wegadziriro yemagetsi. Kana yazvino ikatanga kuchinjisa tsandanyama dzayo nezviuru zvemaamps ichiyerera nemushanduri yako, CT inopindira kuti idzikame kusvika padanho rakachengeteka-kazhinji muchikamu che5 A kana 1 A.

Iwe uchawana maCT akarembera mukati:

• Distribution transformers: Vakomana ava vanoshandira nzvimbo dzekugara kana dzekutengeserana, kazhinji dzinomhanya pamagetsi se11 kV kusvika 33 kV. CTs pano inova nechokwadi chekutarisa uye kuchengetedzwa kwezvino, kuchengetedza mabheti ekuti yakawanda sei muto uri kuyerera nemumitsetse.
• Magetsi emagetsi muzviteshi: CTs inotarisisa iripo pahigh voltage substations uko matransformer anodzika voltage kubva padanho rekutapurirana (semuenzaniso, 132 kV kana kupfuura) kusvika kumazinga ekugovera. Izvo zvakakosha pakuona zvikanganiso uye kukonzeresa dziviriro zvinhu zvisati zvaitika.
• Industrial transformers: Mumafekitori kana nzvimbo dzinorema dzemaindasitiri, vashanduri vanowanzobata mitoro yakakura, uye maCTs aripo kuti atarise mafungu makuru. Kana chimwe chinhu chikatadza, CT inoendesa ruzivo kune masisitimu ekudzivirira anovhara zvinhu pasi midziyo isati yabikwa.

Funga nezve CT seanobhowa pakirabhu-inochengetedza iripo kuti irege kukurisa masisitimu ako edziviriro, uye kana zvinhu zvanyanya kunetsa, CT inoita shuwa kuti mumwe munhu arova emergency stop.

Nei PT uye CT Matter

Pamwe chete, PT uye CT inoumba iyo yekupedzisira buddy cop duo yenyika inoshandura. Ndicho chikonzero vafambisi vanogona kutarisa zvakachengeteka uye kudzora mashandiro etransformer pasina kuswedera pedyo nechikara (vimbi neni, haudi kuswedera pedyo nerudzi irworwo rwemagetsi neazvino pasina dziviriro yakakomba). Kana iri akugovera transformermunharaunda yako kana ahigh-voltage simba transformerkudyisa simba mumaguta ose, PTs uye CTs anogara aripo, kuchengetedza voltage uye ikozvino mumutsara.

Chokwadi chinofadza: Kuchengeta Ziso Pamigumo Yese

Wakambozvibvunza here kuti nei bhiri rako remagetsi rakarurama kudaro? Unogona kutenda CTs uye PTs mukatimetering transformers. Ivo vanoita shuwa kuti vese kambani yekushandisa uye mutengi vanonyatsoziva kuti ingani magetsi ari kudyiwa nekudzika pasi nekuyera voltage uye ikozvino. Saka, hongu, PT uye CT vari kuchengetedza zvinhu zvakaringana uye mativi kumativi ese emagetsi grid.

Mhedziso

Saka, ingave iri shongwe yekutapurirana shanduri kana inoshanda nesimba kugovera shanduri,PT uye CTndiwo magamba asina kuimbwa anoita kuti zvese zvifambe mushe. Ivo vanodzora magetsi akakwira uye mafungu makuru kuitira kuti vanoshanda, relay, uye metres vagone kuzvibata pasina sutu yepamusoro. Nguva inotevera paunobatidza switch yemwenje, rangarira-kune timu yese yevachengeti vemagetsi vanoita shuwa kuti ikozvino nemagetsi zvinozvibata.
