Ho feta meeli ena ho ka fella ka ho se leka-lekane ha khatello ea kelello ka hare, kabo e sa lekaneng ea oli, le ho fokotsa ts'ebetso ea ho kenya letsoho. Ho latela melaoana ea ho kenya transformer ho thibela-likotsi tsa nako e telele.

 

03Pele{1}}Tokisetso ea Tšireletseho ea Instalment

 

3.1 Phallo ea Khatello

3.2 Tlhokomelo ea Boithuto ba Bushing Elevation Base

 

04 Lisebelisoa le Lisebelisoa tse Hlokehang

 

• Thapo e bonolo ya ho phahamisa- hangata bolelele ba 20 m, bophara ba 8-10 mm.(Haeba u sebelisa lithapo tsa tšepe, phuthela ka theipi ea lesela ho thibela tšenyo ea likarolo tsa porcelain kapa tsa tšepe.)
• Ho phahamisa li-screw tsa mahlo- bakeng sa ho kenya bushing e sekametseng.
• Thapo e telele e nang le liboutu tsa M8- bakeng sa ho thaepa ka har'a tube e bohareng ea bushing, le bakeng sa ho phahamisa lihokelo tsa loto kapa lithupa tsa tataiso.
• Wrench ea torque bakeng sa liboutu tsa hex- ho pholletsa le lifolete tsa 16 mm (M10) le 13 mm (M8), sebaka sa torque 10-80 Nm.
• Torque wrench bakeng sa liboutu tsa cylindrical head hex- ho pholletsa le lifolete tsa 6 mm (M8), 5 mm (M6), le 4 mm (M5), torque range 5-30 Nm.
• Wrench e fetolehang- bophara ba mohlahare ho fihlela ho 42 mm, torque 10-80 Nm.
• Padding e bonolo- bakeng sa ho tšehetsa lihlahla nakong ea ho tšoara le ho kenya.

 

Litlhoko tsa Lubrication

Ho thibela ho ts'oaroa ha khoele kapa ho senyeha ho kenngoeng ka terata ka masoba a khoele:

• Likhoele tse amanang le oli ea transformer: sebelisa anhydrous petroleum jelly, grease No.28, kapa oli{1}}lisebelisoa tse ling tse sireletsehileng.
• Likhoele tsa bolt tse thellang: sebelisa grease No.28 kapa e lekanang.
• Li-terminal tsa kantle le li-busbar fastening bolts: sebelisa grease No.28 kapa e lekanang.
• Ho latela lethathamo lena la ho kenya transformer ho netefatsa likhokahano tse nepahetseng tsa mochini le motlakase.

 

05 Ho Phahamisa le ho Tšoara Lihlahla

 

Bakeng sa lihlahla tsa HV (145 kV le holimo), sebelisa libaka tse phahamisang habeli (double hook method), laola angle ea ho phahamisa butle-butle, 'me u qobe ho ama porcelain.

 

 

Haeba e behiloe fatše, tšehetsa lintlheng tse tšoanang le tsa ho paka 'me u sebelise padding e bonolo (rabara kapa lehong).

 

 

06 Mohato-ka-Mohato oa ho Eketsoa ha Bushing

 

1. Hlakola & Hlahloba
Tlosa lihlahla ka har'a liphutheloana 'me u li behe holim'a raka e khethehileng. Hloekisa le ho hlahloba bokaholimo ba porcelain bakeng sa mapetsong kapa mengoo, hlahloba maemo a oli, 'me u netefatse hore ha ho na ho lutla.(Tlhokomeliso: jelly ea petroleum holim'a likhoele e ka qhibiliha tlas'a mocheso o phahameng.)

 

2. Tlhahlobo ea Insulation
Etsa liteko tsa ho kenya letsoho ho kenyeletsoa hore na ho na le eng, -sekirini sa ho qetela, tanδ, capacitance, le ts'ebetso ea oli. Tsoela pele ha liteko tsohle li fetile.

 

3. Ho Phahamisa ka Li-Hook tse peli
Hokela hook ea 1 ho lesale la ho phahamisa flange (mese ea 3-4 ho tloha pheletsong ea pele) 'me u hoke 2 ho porcelain tlas'a flange kapa bracket e phahamisang. Phahamisa ka bobeli ka nako e le 'ngoe, butle-butle u phahamise hook 1 ha u ntse u theola hook ea 2 ho fihlela bushing e lumellana le sebaka sa bophahamo sa bophahamo.

 

4. Lead Wire & Tiiso
Hlakola lithapo tsa lead ka har'a lithapo tsa conductor, kenya likhoele, ebe u kenya cap cap hape, thebe ea grading, le boto ea terminal. Etsa bonnete ba ho tiisa hantle ka holimo. Tšoara ka hloko ho thibela tšenyo ea porcelain.

 

5. Ho tiisa Bolt
Tiisa liboutu ka ho lla butle butle ho thibela khatello e sa lekanang ea flange. U se ke ua feta torque kgothaletswa (20-25 N·m) ho qoba cracking porcelain.

07 Ho kenyeletsoa ha Bushing ea Matla a Phahameng

Sebelisa foreimi e inehetseng ea ho kenya lihlahla 'me u etse tlhahlobo e felletseng. Lihlahla li na le mahlo a mane a phahamisang flange; hokela thapo e kgolo ho jara boima.

 

 

Lintlha tsa bohlokoa:

1. Tlhahlobo & Ho Hloekisa

Hlahloba tšenyo, li-fasteners tse hlephileng, 'me u hloekise lerōle le litšila tsohle. Lekola ho tiisa hape ha ho khoneha.

 

2. Boemo & Tokiso ea Oli

Beha bushing setulong 'me u lokise sekontiri sa oli hore se be bohareng ba-boemo bo ka holimo (~1/2–2/3 ea gauge ea oli).

• Oli e phahame haholo → khatello ea ka hare ea eketseha, e ka baka ho lutla.
• Oli e tlase haholo → e thibela ho shebella.

Fetola oli ka plug ea flange drain kapa plug e tlatsang conservator.

 

3. Keta Khokelo

Kenya karolo e phahameng-mollong oa motlakase ka har'a khoele ea khoele; futhumatsa phosphor boronse filler ho tlatsa le weld lenonyeletso.

 

4. Ho Phahamisa & Ho tsamaisana

Hlakola thapo ea nylon ( E kholo ho feta kapa e lekana le bolelele ba 2 × bushing, matla a lekaneng) ka tube ea conductor ho ea mohatleng oa bushing. Phahamisetsa setsing sa lesoba la transformer; hokela pheletso ea thapo ho sehokelo sa lead ka khoele ea M12. Lokisetsa sekala sa oli 'me u theohe butle-butle ha u ntse u hula loto ho ea holimo ho fihlela sehlahla se lula holim'a tanka ea transfoma.

 

5. Top Structure Tiiso

Dual-seal top: screw positioning nuts, kenya cylindrical pins, ntsha thapo ya nylon, screw lead connector hloohong ea conductor, 'me u tiise ka{1}}sekurufu sa hlooho.

Sebopeho se ntlafetseng sa holimo: kenya lithapo ka ho toba, tlosa thapo ea nylon, tsosolosa hlooho ea conductor, tiisa liboutu tsa hex, 'me u netefatse ho tiisoa hantle. Li-gaskets tsohle tsa rabara li tlameha ho behoa hantle.

 

Lihlahla tsa motlakase tse mahareng le tse tlase li bonolo ho feta lihlahla tsa HV, tse hlokang feela khokahano e tobileng e nang le libaka tse hloekileng le taolo e nepahetseng ea torque.

 

08 Liphoso tse Tloaelehileng tsa ho kenya Bushing

 

09 Teko Pele ho Matlafatsoa

 

Tlohela bushing ho phomola bonyane lihora tse 24. Hloekileng lerōle le mongobo holim'a metsi ho qoba ho tsoa ka ntle ho amang litekanyo tsa ho tsoa (PD). Sebelisa litekanyo tsa litekanyo ho lekola tanδ le ho tsoa ka mokhoa o itseng. Tlosa likatiba tse sireletsang, empa u se ke ua qhaqha kapa ua potoloha li-terminals. Tekanyo ea ho hokahanya e lebisa ho li-terminals le ho etsa liteko ka mokhoa o mong le o mong. Kamora ho etsa liteko, kenya hape likatiba tse sireletsang ho etsa bonnete ba hore mobu o sebetsa hantle.

 

Lintlha:Se ke oa tlosa litekanyo tsa litekanyo nakong ea ho beha leihlo. U se ke ua tlosa li-caps tse sireletsang nakong ea ts'ebetso. Khutlisetsa li-caps tse sireletsang pele ho matlafatsoa. Lihlahla li tlameha ho phomola ho ea holimo (ka tlase ho kapa ho lekana le ho kheloha ha likhato tse 30) bonyane lihora tse 24 pele li sebelisa motlakase.

 

10 Qetello: Boleng ba Tlhophiso bo Etsa Hore ho Tšepahala ho Transformer

 

Bakeng sa li-transformer tse kholo tsa 100, ho kenya li-transformer bushing ho kotsi-le phello e phahameng-. Taolo e nepahetseng ea li-angle tsa ho kenya, torque, ho tiisa, le tlhahlobo ea motlakase e khetha ka kotloloho nako ea bophelo ea transformer, polokeho ea ts'ebetso le litšenyehelo tsa tlhokomelo. Ho latela melao ea ho kenya li-transformer, litataiso, le manane a hlahlobang ho netefatsa ho kenngoa ha li-transformer tse tšepahalang le ts'ebetso e bolokehileng.
