Olana amin’ny resonance amin’ny mpankafy, casing ary singa hafa

■ Antony: Ny resonance amin’ny fan, akorandriaka ary ny singa hafa dia hamokatra tabataba, izay matetika diso amin’ny tabataban’ny transformer.

■ Fomba fitsarana:

1) Shell: Tsindrio ny takelaka aluminium (na takelaka vy) amin’ny akorany amin’ny tananao raha te hahita raha miova ny tabataba. Raha misy fiovana dia midika izany fa ny akorandriaka dia manako.

2) Fan: Mampiasà hazo hazo lava maina hanosehana ny fonon’ny fantson-drano tsirairay mba hahitana raha miova ny tabataba. Raha misy fiovana dia midika izany fa ny mpankafy dia manako.

3) Ampahany hafa: Mampiasà hazo hazo lava maina hanosehana ny ampahany tsirairay amin’ny mpanova (toy ny: kodiara, brackets, sns) mba hahitana raha miova ny tabataba. Raha misy fiovana dia midika izany fa ny ampahany dia manako.

■ Vahaolana:

1) Jereo raha malalaka ny takelaka aluminium (na takelaka vy) amin’ny akorany. Mety ho deforme mandritra ny fametrahana. Mila hanenjanana kokoa ny screws ny akorandriaka, manamboatra ny aluminium takelaka ny akorandriaka, ary hanitsy ny deformed ampahany.

2) Mba hahitana raha malalaka ny mpankafy, dia mila henjana ny bolts famatorana ny mpankafy, ary asio tapa-fingotra kely eo anelanelan’ny mpankafy sy ny fan bracket mba hamahana ny olana ny mpankafy vibration.

3) Raha malalaka ny ampahany amin’ny transformer, dia mila amboarina izy ireo.

olana fametrahana

■ Antony: Ratsy ny fametrahana dia hampitombo ny fihovitrovitran’ny transformer ary hampitombo ny tabataban’ny transformer.

■ Fomba fitsarana:

1) Ny fototry ny transformer dia tsy mafy na fisaka (zoro iray mihantona), na manify loatra ny takelaka ambany.

2) Ny fampiasana vy fantsona hananganana ny transformer dia hampitombo ny tabataba.

■ Vahaolana:

1) Ny fomba fametrahana tany am-boalohany dia tokony hovain’ny vondrona fametrahana.

2) An anti-vibration rubber pad is added under the transformer trolley to solve part of the noise.

Ny fiantraikan’ny tontolo iainana fametrahana

■ Antony: Ny tontolo miasa dia misy fiantraikany amin’ny tabataban’ny mpanova, ary ny tontolo tsy mety dia mampitombo ny tabataban’ny transformer amin’ny 3dB mankany 7dB.

■ Fomba fitsarana:

1) Lehibe sy foana ny efitrano transformer, tsy misy fitaovana hafa sy ako.

2) Ny transformer dia akaiky loatra ny rindrina, latsaky ny 1 metatra. Apetraka eo amin’ny zorony ny transformer, ary ny tabataba hita taratra amin’ny rindrina dia apetraka amin’ny tabataban’ny transformer, izay mampitombo ny tabataba.

3) Ny fiovan’ny solika tany am-boalohany, ny fiovan’ny fiovan’ny maina dia hisy fiantraikany amin’ny tabataban’ny transformer. Ny anton’izany dia somary tery ny efi-tranon’ny mpanova menaka manta, ary misy efitra fivoahana solika sy lavaka misy menaka. Ny transformer dia toy ny apetraka amin’ny boaty fanamafisam-peo.

■ Vahaolana:

Ny fitaovana sasany mitroka feo dia azo apetraka tsara ao an-trano.

04

Olana vibration ny tetezana bus

■ Antony: Noho ny courant lehibe mandalo eo amin’ny sisin’ny busbar dia mihovotrovotra ny busbar noho ny sahan’andriamby mitete. Ny fihovitrovitry ny tetezana fiara fitateram-bahoaka dia hisy fiantraikany lehibe amin’ny tabataban’ny transformer, izay hampitombo ny tabataban’ny transformer mihoatra ny 15dB, izay sarotra ny hitsara. Amin’ny ankapobeny, ny mpampiasa sy ny vondrona fametrahana dia ho diso noho ny tabataban’ny transformer.

■ Fomba fitsarana:

1) Miovaova arakaraka ny entana ny tabataba.

2) Mampiasà hazo hazo hanosehana mafy ny tetezana busbar. Raha miova ny tabataba dia heverina fa manakoako ny tetezana busbar.

3) The bus bar vibrates in the bridge frame, and it is useless to use wooden sticks to top it. It is necessary to open the busbar bridge cover to check whether the busbar is fixed.

■ Vahaolana:

1) Indrindra indrindra ny handrava ny resonance toetry ny busbar tetezana, hanenjanana kokoa na hamaha ny boom screws.

2) Sokafy ny fonon’ny tetezana busbar ary amboary ny busbar.

3) Ny tsipika fivoahana ambany dia mampiasa fifandraisana malefaka.

4) Anontanio ny mpanamboatra ny tetezana busbar hamaha izany.

05

Transformer fototra tena resonance

■ Antony: Misy fanintonana elektromagnetika vokatry ny fiparitahan’ny flux magnetika eo anelanelan’ny tadin’ny takelaka vy silisiôna sy ny lamination.

■ Fomba fitsarana:

1) Ny tabataban’ny transformer dia mafy loatra, ary ny tabataba mahazatra dia mifangaro amin’ny feo hafa.

2) Manjary mihozongozona ny tabataban’ny Transformer.

■ Vahaolana:

1) Henjana ny visy eo amin’ny transformer, anisan’izany ny visy amin’ny tendrony roa amin’ny clamp, ny visy amin’ny lavaka, ary ny visy ho an’ny visy fanerena pad.

2) Ampio pad anti-vibration eo ambanin’ny trolley transformer mba hamahana ny ampahany amin’ny tabataba.

Transformer coil self-resonance

■ Antony: Rehefa misy komandin’ny enta-mavesatra mandalo amin’ny fihodinkodinana, ny fiparitahan’ny flux magnetika ateraky ny komandin’ny enta-mavesatra no mahatonga ny fihovitrovitry ny fihodinkodinana.

■ Fomba fitsarana:

1) Ny tabataban’ny transformer dia mafy loatra, ary ny tabataba dia somary ambany.

2) Rehefa tonga amin’ny ambaratonga iray ny enta-mavesatry ny transformer, dia manomboka miseho ny tabataba, indraindray miseho ary indraindray tsy miseho.

■ Vahaolana:

1) Henjana ny visy rehetra amin’ny sakana spacer mba hampitombo ny hery fanerena axial ny coil.

2) Esory ny visy rehetra amin’ny spacer, esory ny bolts rehetra amin’ny bara varahina mivoaka sy ny bara varahina tsipika aotra, ahetsiketsika ny coil ambany, afindrano ny coil avo lenta amin’ny 3 ka hatramin’ny 5 mm, ary avy eo henjana ny kofehy rehetra. bolts.

07

Ny toetry ny entana

■ Antony: Mivadika ny onjam-peo amin’ny mpanova (toy ny tranganà resonance), ary miteraka tabataba.

■ Fomba fitsarana:

1) Ankoatra ny tabataban’ny transformer mihitsy, dia mifangaro amin’ny tabataba “cluck, cluck”.

2) Ao anatin’ny dingan’ny fandidiana, ny tabataba transformer dia hitombo tampoka, ary hiverina amin’ny laoniny tsy ho ela.

3) Jereo raha misy fitaovana fanitsiana sy fitaovana fiovam-po matetika ao anaty entana.

■ Vahaolana: Mety hieritreritra ny hampiditra fitaovana hampihenana ny harmonic ny mpampiasa.
