sistemu na kudin gaba daya na 110 kV mai zama a tsaki

Atransformer na amfanin kudin gaba daya na 110 kV yana gina aiki mai mahimmanci wajen saita kudin kuma kawo kudin mai yawa. Amma transformer ba za a iya ganin shi da kuma kuma kudin gaba daya na shari'a na elektriku.

Sistemu na kudin gaba daya na transformer yana iya kawo:

• Kudin gaba daya na kudin gaba
• Kudin gaba daya na kudin gaba da kudin gaba daya na kudin gaba
• Kamalinsu na kudin gaba da kudin gaba
• Hankali na kudin gaba daya na transformer
• Kudin gaba daya na shari'a
• Kudin gaba daya na mutane da abubuwa

Don ya sabi wani baya, kuma a yin amfani da neutral grounding ba zai iya ayyana kamar abin da ke cikin abubuwan da suka daga gaba. Ya kamata a saba da kammalawa ta hanyar da transformer winding connection, system grounding philosophy, insulation level, protection scheme da substation grounding grid.

Wannan makala yana bayyana ma'aikatin mafi muhimman, abubuwan da suka daga gaba da kammalawa na engineering na neutral grounding system don 110 kV oil-immersed transformer.

Muhimmanci: Hanyar da ake amfani da neutral grounding ya kamata a saba da system operator da qualified power-system engineers. Ba za a sauran kuma a saba da transformer voltage rating ba.

Menene neutral point na 110 kV transformer?

Idan kada transformer winding na uku a cikin karama ta yanki, ko wye, kada karama suna kawo kafin su a cikin wani babban point. Wannan karama an kira shi da neutral point kuma ana nufin shi da hurufin N.

Neutral yana bada reference point don phase-to-earth voltages. Amma ba za a faruwa da kuma a saba da potential na shi ne kamar da zero ba.

A lokacin yadda ake amfani da shi da kyakkyawan kariya, tashin sa na gaba daya na ƙasa zai iya zama cikin karamin zero. A lokacin da aka samu kariya na gaba daya na ƙasa, kariya na fuskanci, ferroresonance ko wani hali na kariya mai tsoro, tashin kariya na gaba daya zai iya canza matsayin sa.

Don haka, tashin gaba daya da kariyar sa na gaba daya suna bukatar rarraba sosai da:

• Kariyar haɗawa
• Matsayin haɗawa da aka zaune
• Rarrabawar kariya na transformer
• Kariya mai zuwa da kariya ta farko
• Kariya na baki da kariya na fuskanci
• Waktu na aiki na kariya
• Tattaunawa na kariya na siffa

IEC 60076-3 ya bayyana bukatun kariya na transformer, imtihanin dielectric da kariya na gaba daya na kariya da tashin kariya.

Menene TRANSFORMER Kuma a Tsofaffan Kuma?

Kuma na transformer na kuma a tsofaffan kuma shine haɗin da kuma na yankin da ke cikin ƙaramar da ke cikin kuma a duniya.

A cikin kowane tsari na shirye-shiryen, kuma zai iya:

• Kuma a tsofaffan kuma ta hanyar da ke cikin kuma
• Kuma a tsofaffan kuma ta hanyar da ke cikin resistor
• Kuma a tsofaffan kuma ta hanyar da ke cikin reactor

Hanyar ƙarfi na kuma yadda za a iya gudanen kariya na zero-sequence a lokacin da aka kawo kariya daga babban kariya zuwa rani. Yana kuma yadda za a iya gudanen kariya mai zama wajibi, ayyukan relay kuma kariya na kuskure wanda ya bayyana transformer kuma abubuwan da suka hada da shi.

IEEE C62.92 ya bayyana duk manufacta masu muhimmanci wanda ake amfani da su don zabi hanyoyin kuskure na neutral don tabbatar da kariya na kuskure na rani kuma kariya mai zama wajibi a sistemai na utility. Bayaninsa na sistemai na transmission yana kuma bayyana kuskure na neutral na transformer kuma bayani na kuskure na abubuwan da ke amfani da su.

Wace saboda transformer na 110 kV ya bukata kuskure na neutral mai kyau?

1. Tabbatar da kariya na kuskure na rani

A lokacin da kariya daga babban kariya zuwa rani ya faru, hanyar kuskure ya zabi kariya na kuskure na zero-sequence kuma yadda za a iya gudanen kariya.

Wani tsaki na neutral mai gaba daya zai iya ba da kariya mai yawa ga rarraba, wanda ke ba da imkanin abin da suka yi amfani da alamar da suka dace da rarraba a lokacin da aka gaba. Kuma an haifar da kariya ta hanyar impedance wanda ke haifar da kariya da aka rubuta a cikin kimiyya amma ya ba da alama da za a iya gano shi don rarraba.

Hanyar da ke dace zai kasu daga cikin yawan kariya na network, rukunin rarraba da koyon aiki.

2. Haifar da kariya mai yawa na lokacin da aka gaba

A cikin system mai gaba ba da maimakon ko mai gaba ba da maimakon daidai, wani gaba na sau daya zai iya haifar da kariya mai yawa na phase na gaba zuwa gaba, wanda ke haifar da kariya mai yawa na transformer, kabil, switchgear da sauransu hanyoyin da suka dace da kariya.

Wani tsaki na gaba da aka rubuta zai iya taimaka wajen haifar da kariya na neutral da kariya mai yawa na lokacin da aka gaba.

3. Rarraba kariya na neutral na transformer

Wani transformer su yana amfani da insulation mai zama kusa, wanda yana nufin cewa insulation level a kusa da neutral end na winding ya kasance ƙasa don haka a line terminal. Wannan neutral ba za a siya shi zuwa voltage stress ta hanyar kuma yanzu a cikin insulation level na shi.

Yana da mahimmanci in saba da kuma a gano idan graded insulation ke amfani da ita daga transformer design da nameplate—ba a yi hankali ne daga voltage rating alone.

Ko'ina na neutral insulation muna bukatar coordination a tsakanin:

Kankaran sauyi na iya zama mai yawa ga kankaran metal-oxide. Aiki na su na iya haɗawa da zango mai ƙarfi da kankara na gaba daya ta hanyar zango.

Kankara na gaba daya zai dace da tsarin kankara da aiki na sauyi, ba tare da kopya ƙanƙara na gaba daya daga wani matakan sabuwa.

6. Kankaran gaba daya na gaba daya

Kwallon kwalla a tsakiyar neutral zai iya ba sigina na amfani don tabbatarwa transformer da kwallon kwalla.

Kwallon kwalla da aka yi amfani da shi daidai sun hada zuwa:

• Karamin ƙarfi na gaba daya
• Restricted earth-fault protection
• Transformer differential protection
• Gano na yanzu na gap na kula
• Kira da bayanai

Yadda, shakara, kudin gaba daya, kudin kanku, kudin yanzu da kudin ƙarfi na yanzu su dace da shakara na relai da kudin falti na aikata.

7. Kusantar da kudin surji da kusantar da kudin tsofoki

Kusantar da kudin surji ya zabi hanyoyin kudin surji ta hanyar kudin surji. Wani abu ne ya nuna kudin tsofoki.

Kadai kudin kusantar ya zabi ba ta nuna cewa kudin surji ta dace ba. Ta nuna cewa hanyoyin kudin surji sun aiki kuma ya kamata a saba da:

• Kusantar da kudin kariya

Tambaya na counter zai kamata ya kasance ƙarami, daga cikin gaba daya kuma ya kasance da aiki da sauri saboda yadda mai yawa na tambaya zai iya gyara aiki na kariya.

Yaya an yi amfani da surge arrester da protective gap ta hanyar tashin?

Idan suka rufe biyu, surge arrester na neutral da protective gap suna ba da kariya ta hanyar tashin.

Wataƙe arrester

Arrester ana zaɓe shi domin gyara overvoltage na transient kuma ya tsara kariya na mafahimin.

Protective gap

Gap zai iya ba da kariya ta hanyar tashin ko zai iya aiki idan aka bayani overvoltage na temporary ko power-frequency, tare da yadda na scheme.

Koordinatsiyonsu suka iya tabbata cewa:

• Arrester ya ci gaba da transformer a cikin kudin sa na amfani.
• Gap ba za a amfani da shi wajibi ba don tsawon yadda suka dace ba.
