Masere marudzi emota coil kutadza zvikonzero?

Kana iyo mota iri munzvimbo isina kujairika yekushanda (kusanganisira magetsi, mechanika uye zvakatipoteredza), hupenyu hwemota coil huchapfupikiswa zvakanyanya.Zvikonzero zvekutadza kweiyo fan coil ndezvi: kurasikirwa kwechikamu, kupfupika, coil grounding, overload, rotor lock, voltage kusaenzana, uye kuvhiya.Pazasi pane mifananidzo yeakasiyana coil kutadza kukubatsira kuziva chikonzero chekutadza (tora 4-pole mota semuenzaniso)..

1. Mufananidzo mutsva wecoil

2. Kushaya chikamu

Kushaikwa kwechikamu ndiyo dunhu rakavhurika rechikamu chimwe chemagetsi ekupa, chikonzero chikuru ndechekuti fuse yechikamu chimwe inovhuvhuta, iyo contactor yakavhurika, kana tambo yemagetsi yechikamu chimwe yakatyoka.

Star connection (Y connection) Delta connection

Mufananidzo uri pamusoro apa mufananidzo we4-pole mota ichipiswa kunze kwekurasikirwa kwechikamu.Symmetrical burnout yemota coils idanho-kushaya kupera simba.Kana iyo nzira yekubatanidza nyeredzi isiri muchikamu, zvakanaka kuti mota ine mapango maviri ingove nemaseti maviri emakoiri, uye 4-pole mota kuti ipise zvakaenzana seti ina chete yemakoiri.Iyo seti yemakoiri yakanaka;kana iyo delta yekubatanidza yabuda muchikamu, mota ye2-pole inopisa seti mbiri dzemakoiri akaenzana, uye 4-pole mota inopisa seti mana emakoiri akaenzana.

3. Short circuit

Mifananidzo inotevera inoratidza kuti kutadza kwemota kunokonzerwa nekusvibiswa, kupfeka, kudedera, nezvimwe.

4. Coil grounding

Mifananidzo inotevera inoratidza kuti kutadza kwemota kunokonzerwa nekusvibiswa, kupfeka, kudedera, nezvimwe.

Motor notch breakdown Inter-slot breakdown

5. Overload

Kuremedza mota kuchaita kuti mota iwande.

Ongorora: Zvese zviri pasi-voltage uye over-voltage zvinogona kukonzera kukuvara kwekudzivirira uye kukonzera kuwandisa.

6. Rotor yakavharwa

Mamiriro ezvinhu aya anokonzeresa kupisa kwakawanda mumotokari, kazhinji nekuda kwekutanga kutanga kana kudzokororwa kazhinji kwemota.

7. Kusaenzana kwematatu-phase voltage

Magetsi asina kuenzana anokonzeresa kukanganisa kwekudzivirira, izvo zvingave zvichikonzerwa nekusagadzikana kwemagetsi uye kushata waya.

Cherechedza: A one percent voltage kusaenzana kunogona kukonzera matanhatu kusvika gumi muzana kusaenzana kwazvino.

8. Kuvhiya

Mamiriro ezvinhu anoratidzwa mumufananidzo uri pasi apa anowanzokonzerwa nekuwedzera kwesimba.Magetsi emagetsi anogona kukonzerwa nemidziyo yemagetsi senge magidhi emagetsi, mheni, capacitors, nezvimwe.
