Li-interlock tsa Kirk Key li na le mefuta e mengata ho pholletsa le mefuta ea li-transformer-ho tloha libakeng tsa bolulo tsa padmount ho ea ho li-transformer tsa indasteri. Ka tlase ke lits'ebetso tse atileng haholo, tse nang le ts'ebetso e qaqileng:

 

6.1 Kopo ea 1: Likhabinete tsa Padmount Transformer (Bolulo/Khoebo)

• Sepheo: Thibela-basebetsi ba sa lumelloeng (mohlala, basebetsi, borakonteraka) ho bula lik'habote tse phelang.
• Tlhophiso: Khokahano e le 'ngoe mochining o ka holimo oa lisebelisoa (mohlala, switch ea 12kV load break switch) le e 'ngoe khabineteng.
• Mokhoa oa ho sebetsa: Joalokaha ho hlalositsoe Karolong ea 2-feela ka mor'a hore sesebelisoa sa utility se buloe ('me senotlolo se lokolloe) khabinete e ka fumanoa. Sena se bohlokoa bakeng sa ho fokotsa likotsi tsa arc flash nakong ea tlhahlobo ea metara kapa tlhokomelo e nyane.

 

6.2 Kopo ea 2: Liphetoho tsa Load Break (Industrial Transformers)

Sepheo: Thibela ts'ebetso e ts'oanang ea li-switches tse peli tsa khefu ea mojaro (LBS) ho potoloho ea bobeli ea transformer (e bakang lipotoloho tse khutšoane).

Tlhophiso: Li-interlocks tse peli tsa HD Series (e le 'ngoe ho LBS e' ngoe le e 'ngoe) e hokahantsoeng ka senotlolo se arolelanoang.

Mokhoa oa ho sebetsa:

• Ha LBS A e koetsoe, senotlolo se qabeletsoe ka har'a interlock ea eona{0}LBS B's interlock bolt ea atolosoa, e thibelang hore e se koale.
• Ho kwala LBS B, opareitara e bula LBS A, e lata senotlolo, mme e se sebedise ho hula boutu ya LBS B-ho tshwasa senotlolo se hokelang LBS B (e thiba LBS A ho tswala-botjha).

 

 

 

 

 

Ho khetha interlock e nepahetseng ho hloka ho hokahanya lintlha le tikoloho ea transformer ea hau, boholo le litlhoko tsa ts'ebetso. Ka tlase ke mehato{1}ka{2}}mohato oa khetho:

7.1 Mohato oa 1: Fumana Letoto (SD vs. HD)

Sebelisa lethathamo lena ho etsa qeto:

Ntlha	Khetha SD Series	Khetha HD Series
Tikoloho	Ka ntle / ka ntle (ho se na pula e tobileng / letsoai)	Ka ntle / lebopong la leoatle / indasteri (pula, letsoai, mocheso o phahameng)

Kotsi ea Corrosion	Tlase (moea o omileng, o hloekileng)	Phahameng (mongobo, letsoai, lik'hemik'hale)

 

7.2 Mohato oa 2: Kgetha Bolelele ba Bolt

Bolelele ba bolt bo itšetlehile ka sebaka se pakeng tsa interlock le lets'oao la switch / latch ea cabinet. Lekanya sekheo sena (e bitse "G") 'me u kenye 1/8" ho netefatsa hore ho kopana ho feletseng.

1" (25.4mm): Likhabinete tse tšesaane tsa li-transformer tsa ka tlung.

1.5" (38.1mm): Likhabinete tse tloaelehileng tsa transfoma ea padmount.

7.3 Mohato oa 3: Khetha Bongata ba Cylinder

• 1 Cylinder: Litlhophiso tse bonolo (1 switjha + 1 khabinete).
• Li-cylinders tse 2–4: Li-transformer tsa indasteri tse nang le li-switches tse peli (mohlala, LBS ea mathomo le ea bobeli).
• 5+ Li-cylinders: Litsamaiso tsa phepelo ea liluru kapa li-transformer tse nang le lintlha tse ngata tsa polokeho (sebelisa foromo ea bolelele: 9.5" + 1.5" ka silindara e 'ngoe) .

 

7.4 Mohato oa 4: Eketsa Li-swichi tsa Thuso (Haeba ho Hlokahala)

Bakeng sa li-transformer tse hlokang tlhokomelo e hole (mohlala, litsamaiso tsa taolo ea indasteri), eketsa li-switches tse thusang:

• Letoto la SD: Likhetho li kenyelletsa 2 N/O 1 N/C (Karolo ea A) kapa 4 N/O 2 N/C (Karolo ea B).
• Letoto la HD: Khetho e tloaelehileng ke 1 N / O (Karolo ea E tatellano); Litlhophiso tsa moetlo li hloka ho buisana le sehlopha sa barekisi sa Kirk.

 

7.5 Mohato oa 5: Netefatsa Tumellano le Lisetifikeiti

Netefatsa hore interlock e kopana le maemo a lehae:

• UL e thathamisitsoe (bakeng sa Amerika Leboea) kapa CSA e netefalitsoeng (bakeng sa Canada).
• NFPA 70E e lumellana (polokeho ea arc flash).

Li-transformer li kotsi-lintho tse ngata tse kotsi-diketsahalo tsa arc flash li ka baka kotsi e mpe kapa lefu, 'me tšenyo ea lisebelisoa e ka fella ka ho tima ka litšenyehelo tse ngata. Li-interlock tsa Kirk Key li sebetsana le likotsi tsena ka litsela tseo ho seng sesebelisoa se seng sa polokeho se ka khonang:

8.1 E tiisa Tšireletseho ea "No Bypass".

Ho fapana le linotlolo tsa elektroniki (tse ka senyehang ha motlakase o khaoha) kapa lilotlolo (tse ka khaoloang kapa tsa hlokomolohuoa), li-interlock tsa Kirk Key li itšetlehile ka tšebetso ea 'mele{0}}ha ho mokhoa oa ho feta tatellano. Ka mohlala, senotlolo se ka har'a khabinete ea transformer se ka tlosoa ka li-bolt cutters, empa senotlolo sa Kirk Key se hloka hore switch ea holimo e tlosoe{2}}matla pele .

 

8.2 E Fokotsa Phoso ea Batho

NFPA 70E e tlaleha hore 70% ea liketsahalo tsa motlakase li bakoa ke liphoso tsa batho (mohlala, ho bula khabinete e phelang). Li-interlocks tsa Kirk Key li felisa sena ka ho etsa liketso tse sa sireletsehangho se kgonehe mmeleng-notlolo ha e khone ho fumanwa hape, le boutu e ka se hulwe morao, ho fihlela sisteme e bolokehile.

 

8.3 Litšenyehelo-Nako e Tlamahatsang-Nako
