Sida loo xisaabiyo capacitor-upka xira motor saddex waji leh oo wajiga kaliya

Waxaa dhacaya sidan: waxaa jira in yar oo wanaagsan mashiinka, mishiinka qodista ama lathe, ku shaqeeya by 380 volts. Waxaa lagu rakibi laga yaabaa in workshop guri ama aqalada ah. Laakiin dhibta, ee goobahaasi waxaa kaliya waa saldhig caadiga ah.

Xaaladaha halkaas oo aad u baahan tahay in ay ku xidhmaan motor koronto saddex waji leh, oo waa isha danab-hal wajiga kaliya ee la heli karo, ka mid ah xaaladda sida ugu macquulsan, laadyo mid ka mid ah windings ku dhex element wajiga wareegaayo ah - laga bilaabo capacitor. Sidaas waxaa suurtagal ah si ay u helaan bedelka saddexaad wareejiyay by 120 digrii danab wajiga.

In kiiska ku haboon, dardargelinta motor ka capacitance weyn oo loo baahan yahay, iyo gaarey xawaaraha magacaaban angular - kale, yar. Si arrintan loo sameeyo, ka codsan nidaamka, taas oo ka dhigaysa waxaa suurto gal ah in gab awooda xad-dhaaf ah in hab Buugga iyo si toos ah labadaba, kaliya qiimaha shaqada ay.

Haddii ay dhacdo in ay ku xiran fuuli in xiddiga, awoodda shaqo taarikada condenser ah waxaa lagu go'aamiyaa formula ah:

CP = 2800 (I / U)

In the case of xiriir la xidhiidha Delta waa kala duwan:

CP = 4800 (I / U)

Si kastaba ha ahaatee, xidhiidhka ka mid ah saddex-xagalka windings motor loo baahnayn, sababtoo ah kiiskan danab ka mid ah hadda talantaalli ah waa in ay ahaataa 380 volts at mid kasta oo iyaga ka mid ah, iyo in shabakadaha guriga - 220 oo kaliya.

formula waxaa loo isticmaali karaa si ay u fududeeyaan qiimaha xisaabinta capacitance ah, ku dheehan

CP = F / 10

CN = F / 5

halkaas oo

P - Power, watts;

C - bilowga capacitance, Ji;

C - bilowga capacitance, Matt.

Sidaas darteed, laga bilaabo capacitance capacitor waa in ay ahaataa badh ilaa laba iyo badh jeer shaqada ka badan.

Xiisadda in hadda AC caadiga ah waa 220 volts. Su'aasha u kacaya oo ku saabsan sida si loo ogaado xaddiga hadda, muuqday formula ee kor ku xusan.

Way fududahay. xoog lagu qiimeeyo ee engine waxaa lagu gartaa, waxaa ku qoran qoraalka ku lifaaqan si uu jirka, oo wuxuu u adeegaa sida nooc ka mid ah baasaboorka.

I = P / (1,73 U sababtoo ah φ),

halkaas oo

I - amp qiimaha hadda;

U - danab ee (220 V);

φ - xagal wajiga.

Si sax ah xisaabinta iyo kor u qaadaaya capacitor-upka motor koronto, waxaa ku xiran in sahayda-hal waji ficil nooc kasta oo matoorrada saddex waji. Qaar ka mid ah si fiican u shaqayn doonaa, in uu yahay, astaamaha ay noqon doontaa mid ka dhow yahay inuu nameplate ee ay ka mid noqoshada joogto ah (tusaale ahaan, AOL Taxanaha, UAD, APN). MA taxane, ka tarjumaya in ay design nidaamka la dabaqay double qafis qafis rotor, doonista ha muujin ugu xumaa natiijada.

Qaadaaya capacitor-upka waa in ay tixgeliyaan xaqiiqada ah in bilowgii mid ka mid ah qiimaha hadda oo si weyn u badnaan qiimaha magacaaban. Sidaas darteed, waa in la xusuusnaado in qaybta cross silig, bixinta awood engine ee, waa in loo doortay la margin ah.

Hadda oo capacitor bilowga ah waxaa loo isticmaali karaa in ay ku xidhmaan motor saddex waji leh ee network-hal waji. taangiga Electrolytic waxaa loo isticmaali karaa, laakiin joogidda ee dioska- rectifier circuit u adkayn iyo hoos u halaynta guud ee nidaamka oo dhan. Xitaa Henry Ford unbaa ku dooday in qaybo yar yar, hoose fursad of dillaacin.

Ka fudud oo ka kalsoonaan karo in la dhiso inrush capacitor warqad ah. danab ayaa tilmaamay on guryaha waa in ka badan 220 Volts.
