Masalah resonansi penggemar, casing, lan komponen liyane

■ Alesan: Resonansi penggemar, cangkang lan komponen liyane bakal ngasilake gangguan, sing umume salah kanggo gangguan trafo.

■ Metode putusan:

1) Shell: Press the aluminum plate (or steel plate) of the shell with your hand to see if the noise changes. If there is a change, it means that the shell is resonating.

2) Kipas angin: Gunakake tongkat kayu dawa sing garing kanggo nyurung casing saben penggemar kanggo ndeleng manawa owah-owahan swara. Yen ana owah-owahan, tegese kipas kasebut resoning.

3) Bagéan liya: Gunakake kelet kayu dawa garing kanggo push saben bagean saka trafo (kayata: gembong, penggemar krenjang, etc.) kanggo ndeleng apa owah-owahan swara. Yen ana owah-owahan, tegese bagean-bagean kasebut resonate.

■ Solusi:

1) Priksa manawa piring aluminium (utawa piring baja) cangkang wis kenthel. Bisa deformed sak instalasi. Sampeyan kudu ngencengi sekrup cangkang, ndandani piring aluminium cangkang, lan mbenerake bagian sing cacat.

2) Kanggo ndeleng yen penggemar wis ngeculke, sampeyan kudu ngencengi bolts fastening saka penggemar, lan sijine Piece cilik saka karet antarane penggemar lan krenjang penggemar kanggo ngatasi masalah getaran penggemar.

3) Yen bagean saka trafo ngeculke, padha kudu didandani.

masalah instalasi

■ Alesan: Instalasi miskin bakal aggravate geter trafo lan amplify gangguan saka trafo.

■ Metode putusan:

1) Pondasi trafo ora kuwat utawa warata (siji sudhut dilereni soko tugas), utawa piring ngisor banget tipis.

2) Nggunakake baja saluran kanggo mbangun trafo bakal nambah gangguan.

■ Solusi:

1) Cara instalasi asli kudu diowahi dening unit instalasi.

2) Pad karet anti-geter ditambahake ing troli trafo kanggo ngatasi gangguan.

03

Pengaruh lingkungan instalasi

■ Alesan: Lingkungan operasi mengaruhi gangguan saka trafo, lan lingkungan unfavorable mundhak gangguan saka trafo dening 3dB kanggo 7dB.

■ Metode putusan:

1) Kamar trafo gedhe lan kosong, ora ana peralatan lan gema liyane.

2) Trafo cedhak banget karo tembok, kurang saka 1 meter. Trafo diselehake ing pojok, lan gangguan sing dibayangke dening tembok ditumpangake ing gangguan trafo, sing nambah gangguan.

3) Originally digunakake pangowahan lenga, ngganti kanggo owah-owahan garing bakal mengaruhi gangguan saka trafo. Alasane yaiku ruang transformator minyak mentah relatif sempit, lan ana kamar bocor minyak lan bolongan bocor minyak. Trafo kaya dilebokake ing kothak swara.

■ Solusi:

Sawetara bahan nyerep swara bisa dipasang kanthi bener ing jero ruangan.

04

Masalah geter jembatan bis

■ Alesan: Amarga arus gedhe sing ngliwati busbar sisih, busbar kedher amarga medan magnet sing bocor. Getaran jembatan bis bakal nyebabake gangguan trafo, sing bakal nambah gangguan trafo kanthi luwih saka 15dB, sing angel diadili. Umume, pangguna lan unit instalasi bakal salah amarga gangguan trafo.

■ Metode putusan:

1) Swara beda-beda gumantung karo beban.

2) Gunakake tongkat kayu kanggo nyurung jembatan busbar kanthi kuat. Yen owah-owahan swara, dianggep jembatan busbar resonating.

3) Bar bis kedher ing pigura kreteg, lan iku ora ana gunane kanggo nggunakake teken kayu kanggo ndhuwur iku. Sampeyan perlu kanggo mbukak tutup jembatan busbar kanggo mriksa apa busbar wis tetep.

■ Solusi:

1) Utamane kanggo numpes kondisi resonansi jembatan busbar, ngencengi utawa ngeculake sekrup boom.

2) Bukak tutup jembatan busbar lan ndandani busbar.

3) Garis metu voltase kurang nganggo sambungan alus.

4) Takon produsen jembatan busbar kanggo ngatasi.

05

Transformer core self-resonance

■ Alesan: Ana daya tarik elektromagnetik sing disebabake dening kebocoran fluks magnet ing antarane sambungan lembaran baja silikon lan laminasi.

■ Metode putusan:

1) Swara trafo banter banget, lan swara normal dicampur karo swara liyane.

2) Transformer noise becomes wavy.

■ Solusi:

1) Kencengake sekrup ing trafo, kalebu sekrup ing ujung penjepit, sekrup liwat bolongan, lan sekrup kanggo sekrup tekanan pad.

2) Tambah bantalan anti-geter ing troli trafo kanggo ngatasi gangguan.

Resonansi diri kumparan trafo

■ Alesan: Nalika ana beban saiki liwat nduwurke tumpukan, kebocoran fluks Magnetik kui dening beban saiki nyebabake geter saka nduwurke tumpukan.

■ Metode putusan:

1) Swara trafo banter banget, lan swarane rada sithik.

2) Nalika beban trafo tekan tingkat tartamtu, gangguan wiwit katon, kadhangkala katon lan kadhangkala ora katon.

■ Solusi:

1) Kenceng kabeh ngawut-awut saka pemblokiran spacer kanggo nambah pasukan komprèsi aksial saka kumparan.

2) Loosen kabeh ngawut-awut saka spacer, loosen kabeh bolts ing metu tembaga bar lan nul baris tembaga bar, goyangake coil kurang voltase, mindhah kumparan voltase dhuwur dening 3 kanggo 5 mm, banjur kenceng kabeh baut.

07

Sifat momotan

■ Reason: The voltage waveform of the transformer is distorted (such as resonance phenomenon), and noise is generated.

■ Metode putusan:

1) Saliyane swara trafo dhewe, swara kasebut uga dicampur karo swara “cluck, cluck”.

2) Ing proses operasi, gangguan trafo dumadakan bakal nambah banget, lan bakal bali menyang normal rauh.

3) Priksa manawa ana peralatan rectification lan peralatan konversi frekuensi ing beban.

■ Solusi: Pangguna bisa nimbang nambah piranti kanggo nyuda harmonik.
