2100 kVA Mofuta o Omileng oa Phatlalatso Transformer-13.8/0.46 kV|Afrika Boroa 2024

01 Kakaretso

1.1 Tlhaloso ea Morero

E etselitsoe moreki oa Afrika Boroa ka 2024, transformer ena ea 2100 kVA ea mofuta o omileng e na le mapheo a kentsoeng ka botlalo ka har'a epoxy resin. Kaha ha e na oli-e fokotsa kotsi ea mollo le tšilafalo ea tikoloho. E nang le insulation ea Sehlopha sa F e lekantsoeng bakeng sa mocheso o sebetsang ho fihla ho 155 degrees.

Transformer e lekantsoe ho 2100 kVA, e nang le motlakase o ka sehloohong oa 13.8 kV le motlakase oa bobeli oa 0.468 kV (468 V). E loketse ho matlafatsa li-hoists tsa morafo le lisebelisoa tse boima tsa ho sebetsa tse sebetsang ho 468 V.

Sehlopha sa eona sa vector ke D({0}}℃)d0, moo lehlakore le phahameng-voltage le nang le +15 shift phase phase. Moralo ona o kopana le litlhoko tsa mohato oa sistimi mme o thusa ho fokotsa li-harmonics le maqhubu a potolohang nakong ea ts'ebetso e ts'oanang.

Koko e entsoe ka tšepe ea silicon e nang le lijo-thollo, e fanang ka tahlehelo e tlase le matla a matla a khoheli, a tlatsetsang ho tahlehelo e tlase ea -moroalo oa 3.2 kW.

E na le mochine o laolang mocheso le motlakase oa hona joale (5000 / 1 CT), transformer e tšehetsa ho shebella le ho sireletsa mocheso o tsitsitseng, hammoho le tekanyo ea hona joale, ho thusa ho kopanya mekhoa ea tšireletso le ea ho shebella.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

The 2100 kVA three-mohato o ommeng oa transformer core o sebelisa lijo-thollo-mashiti a tšepe a silicon a tšehelitsoeng ka matla a khoheli a phahameng, a ntlafatsa ts'ebetso ea makenete ea motlakase le ho fokotsa tahlehelo ea mantlha. Maqephe ana a na le mekhoa e matla ea ho mamella ho sebetsa le khatello ea nako e telele{{4}. SCOTECH e netefatsa li-burrs Ka tlase kapa ho lekana le 0.02mm mme ha ho na liphoso. Theko e stakaneng e tlositsoe ka mongobo{8}e leng epoxy resin bakeng sa ho tšoarella le ho sireletsa mongobo.

2.2 Ho tsubella

Transformer ea mofuta o omileng e na le mapheo a mabeli, ka bobeli a hahiloe ka li-conductors tsa aluminium tse tšoarellang ho netefatsa ts'ebetso e ntle haholo le bophelo bo bolelele ba ts'ebeletso. Maqhubu 'ohle a sirelelitsoe ka lisebelisoa tsa ho ikemela tsa Sehlopha sa F, 'me khoele kaofela e kentsoe ka sesepa sa epoxy sa Sehlopha sa F, 'me se etsa mohatsela o tiileng,{1}}o sa keneleng mocheso le o tsitsitseng mochesong oa mocheso.

2.3 kopano ea ho qetela

Likarolo tsa mantlha tse entsoeng le tse matsoelintsoeke lia bokelloa, nakong eo likhokahano tsa motlakase, ho kenya letsoho le ho lokisa sebopeho li etsoang.

Tlas'a vacuum, epoxy resin e tšeloa lipakeng tsa mapheo le mokokotlo, ho etsa sebopeho se tiileng, se phekotsoeng.

Kamora ho bokana le ho folisa, letoto la liteko tsa motlakase le tsa mochini li etsoa ho netefatsa hore transformer e kopana le moralo le litekanyetso tsa polokeho.

05 Sebaka le Kakaretso

Transformer ena ea 2100 kVA resin cast dry distribution e etselitsoe moreki oa Afrika Boroa ka ho khetheha. Transformer ena e loketse metjhini e boima-ka ho khetheha, lienjene tse kholo, le lisebelisoa tsa ho sebetsa merafong le lits'ebetsong tsa indasteri tse hlokang boima bo bongata. SCOTECH e ikemiselitse ho fana ka ts'ebetso ea profeshenale le lits'ebeletso tsa boleng ho fihlela litlhoko tsa hau.

Joaloka moetsi oa li-transformer tsa mofuta o omileng, SCOTECH e fana ka lihlahisoa tse tsamaellanang le maemo a machabeng joalo ka IEC, ANSI/IEEE, NEMA, CSA, le BS. Li-transformer tsa rona tsa mofuta o omileng li koahela matla a lekantsoeng ho tloha ho 50 kVA ho fihla ho 15 MVA, ka matla a phahameng a fihlang ho 36 kV. Ka bobeli maqhubu a 50 Hz le 60 Hz a teng, ka likhokahano tsa delta kapa linaleli. Maqhubu a motlakase a mahareng a kentsoe ka har'a resin ea epoxy, ka litlelase tsa ho kenya letsoho ho tloha ho A, E, B, F ho isa H, le maemo a ts'ireletso a ka khonehang ho tloha IP 2X ho isa IP 4X.

Likhetho tse pholileng li kenyelletsa pholiso ea moea ea tlhaho (ONAN) le pholiso ea moea e qobelloang (ONAF), e nang le li-sensor tse ngata tsa mocheso le li-relay tsa mocheso bakeng sa ts'ireletso e tšepahalang ea mocheso. Hape re fana ka lisebelisoa tse kang mabili, li-transformer tsa hajoale, ho-load tap changer (OLTC), le mabokose a marshalling ho khotsofatsa litlhoko tse fapaneng tsa bareki.
