Waa maxayKondenser-ka Snubber?

Nidaamyada casriga ah ee korontada iyo elektaroonigga ah, aaladaha beddela sida transistors-ka, thyristor-rada (SCR), IGBT-yada, iyo relays-ku waxay door muhiim ah ka ciyaaraan. Si kastaba ha ahaatee, aaladahani waxay inta badan la kulmaan koror danab ah iyo isbeddello degdeg ah oo ku yimaada hadda oo ay ugu wacan tahay culaysyada inductive-ka, kuwaas oo horseedi kara burbur, cillado, iyo faragelin koronto oo aan loo baahnayn (EMI). Halkan waa meesha ay ku taalcapacitors-ka snubber-ka ahsoo gal ciyaarta.

Fahmidda Kaabayaasha Snubber

A capacitor-ka snubberwaa kapastar gaar ah oo loo isticmaalo wareegyada snubber si looga ilaaliyo aaladaha beddelka kor u kaca danabka iyo durdurrada ku-meel-gaarka ah. Iyagoo bixinaya waddo kale oo ku meel gaar ah oo loogu talagalay hadda, kapastarka snubber waxay gacan ka geystaan ​​​​yareynta walbahaarka ku yimaada qaybaha beddelka, kordhinta cimrigooda, iyo hagaajinta isku halaynta wareegga.

Maxaa loogu baahan yahay wareegyada Snubber?

Qalabka nadiifinta ilkaha waxaa loo isticmaalaa habab kala duwan, oo ay ku jiraan:

• Wareegyada korontada- si loo xakameeyo kor u kaca danabka.
• Wareegyada Relay iyo contactor-ka- si loo yareeyo qaab-dhismeedka qaansada ee ka dhexeeya xiriirada.
• Isbedelada Semiconductor-ka (SCR, IGBT, GTO, iwm.)- si loo xaddido kororka danabka (dV/dt) iyo kororka hadda (di/dt), ka hortagga kicinta beenta ah iyo cilladda qalabka.

Sidee bay u shaqeeyaan wareegyada Snubber?

Wareegyada Snubber waxay caadi ahaan ka kooban yihiin capacitor amaShabakadda iska caabbinta-capacitor (RC)oo la dhigay qalab beddel ah.

• Xakamaynta Kororka Danabka:Marka SCR ama transistor uu damo, culayska inductive-ku wuxuu dhaliyaa koror danab sare. Kaadhka snubber-ka ah ayaa nuugaya tamartan, taasoo ka hortagaysa cadaadiska danabka xad-dhaafka ah.
• Xakamaynta dV/dt:Kondensarku wuxuu hoos u dhigaa heerka kor u kaca danabka ee ku wareegsan badhanka, isagoo ka fogaanaya shid aan la filayn (kicinta beenta ah) ee thyristor-yada iyo semiconductor-yada kale.
• Xakamaynta di/dt:Ku darista iska caabin taxane ah oo leh kaabsoosha waxay xaddidaysaa qulqulka inrush marka badhanka shidmo, taasoo ka hortagaysa cadaadiska xad-dhaafka ah ee qaybta.

Astaamaha Muhiimka ah ee Capacitors-ka Snubber

Kaabsadeyaasha Snubber waxaa loogu talagalay inay xakameeyaan qulqulka soo noqnoqda iyo garaaca soo noqnoqda. Astaamaha muhiimka ah waxaa ka mid ah:

• Soo noqnoqoshada hawlgalka oo la oggol yahay (100 kHz ama ka badan).
• Is-kuleyl hooseeya iyo khasaaro yar.
• Iska caabinta taxanaha oo hooseysa (ESR) si loo helo nuugid tamar oo hufan.
• Awoodda korontada iyo korontada oo sareysa si loo maareeyo culaysyada ku meel gaarka ah.

Noocyada Kaabayaasha Snubber

Kaabsoodhada Snubber waxay ku yimaadaan noocyo kala duwan iyadoo lagu saleynayo heerarka awoodda iyo shuruudaha codsiga:

• Kondenser-yada dhoobada– Ku habboon codsiyada awoodda yar.
• Kondenser-yada Filimada Balaastikada ah- Waxaa loo isticmaalaa wareegyada korontada sare leh, oo ay ku jiraan nidaamyada baabuurta korontada ku shaqeeya (EV) iyo kontaroolada matoorka.
• Kondenser-yada Polypropylene (MPP) ee Birta ah- Waxaa loogu talagalay codsiyada soo noqnoqda sare leh, kuwa hadda jira oo leh soo-jiidasho hoose.

Doorashada Kondenser-ka Snubber-ka ee Saxda ah

Xulashada capacitor-ka snubber waxay ku xiran tahay arrimo ay ka mid yihiin:

• Qiimaha Awoodda:Caadiyan waxay u dhaxaysaa laga bilaabo0.1µF ilaa 10µF, iyadoo ku xiran qalabka beddelka iyo soo-jiidashada culayska.
• Qiimaynta danab:Waa inay ka sarreysaa danabka ugu sarreeya ee wareegga.
• ESR iyo qiimeynta hadda jirta:Waa inay ahaataa mid hoose oo ku filan si ay u xakamayso qulqulka hirarka iyada oo aan lahayn kuleyl xad dhaaf ah.

Xaggee loo isticmaalaa Kondenser-ka Snubber?

Kaadhadhka Snubber waxaa laga helaa warshado iyo codsiyo kala duwan, sida:

• Cutubyada korontada (PSUs)
• Gawaarida korontada (EVs) iyo wareegyada xakamaynta matoorada
• Nidaamyada otomaatiga warshadaha
• Nidaamyada tamarta la cusboonaysiin karo (kuwa tamarta qoraxda ku shaqeeya, marawaxadaha dabaysha)

Gunaanad

Kaadhadhka Snubber waxay door muhiim ah ka ciyaaraan ilaalinta aaladaha beddelka ee ka yimaada kor u kaca danabka, xakamaynta qulqulka ku-meel-gaarka ah, iyo kor u qaadista waxqabadka wareegga guud. Maadaama elektaroonigga korontada uu sii socdo, baahida loo qabo kaadhadhka snubber-ka ee hufan oo la isku halleyn karo ayaa sii kordheysa. Hadday tahay sahayda korontada, otomaatiga warshadaha, ama baabuurta korontada, kaadhadhkani waxay gacan ka geystaan ​​​​hubinta hawlgal siman oo xasilloon oo ka dhaca wareegyada awoodda sare leh.
