Binciken Dalilin Kona Thyristor

A lokacin amfani da matsakaicin mitar tanderu, thyristor konewa sau da yawa faruwa, wanda sau da yawa yakan ɓata ma'aikatan kulawa na tsaka-tsakin wutar lantarki, kuma wani lokacin ba zai iya magance su ba.Dangane da bayanan kulawa na tanderun mitar matsakaici na shekaru masu yawa, ana iya ganin bayanan a ƙasa don tunani ta ma'aikatan kulawa.

1.The ruwa sanyaya jacket na inverter thyristor aka yanke ko sanyaya sakamako da aka rage, don haka ruwa sanyaya hannun riga bukatar a maye gurbinsu.Wani lokaci ya isa ya lura da yawan ruwa da matsa lamba na jaket mai sanyaya ruwa, amma sau da yawa saboda matsalar ingancin ruwa, an haɗa ma'auni na ma'auni zuwa bango na jaket mai sanyaya ruwa.Saboda ma'auni shine nau'in nau'i na nau'i na thermal conductivity bambance-bambance ko da yake akwai isassun kwararar ruwa, tasirin zafi yana raguwa sosai saboda keɓewar sikelin.Hanyar yin hukunci ita ce wutar lantarki tana aiki da ƙarfin kusan mintuna goma ƙasa da na ƙimar da ta cika.Daga nan sai wutar ta tsaya da sauri, kuma ainihin sinadarin da ke sarrafa silikon ya taɓa hannu da sauri bayan ya tsaya.Idan ya ji zafi, wannan dalili ne ya jawo laifin.

2.Haɗin da ke tsakanin tsagi da madugu ba shi da kyau kuma ya karye.Bincika ramin kuma haɗa wayoyi, kuma sarrafa su gwargwadon halin da ake ciki.Lokacin da tashar tashar tashar tashar tashar ta kasance tana da yanayin ƙulla mummunan lamba ko layin da aka karya, ƙarfin wutar lantarki zuwa wani ƙima zai haifar da yanayin wuta, wanda ke shafar aikin al'ada na kayan aiki, wanda ke haifar da kariya ga kayan aiki.Wani lokaci ana haifar da overvoltage na wucin gadi a ƙarshen ƙarshen thyristor saboda taya.Shi kariyar overvoltage ya yi latti, zai lalata sinadarin thynstor.Ƙunƙarar ƙarfin ƙarfi da kuma ƙararrawa sau da yawa suna faruwa a lokaci guda.

3.The nan take burr ƙarfin lantarki na thyristor yayi yawa sosai lokacin da thyristor aka juya.A cikin babban da'ira na matsakaicin mitar wutar lantarki, juriya da sha.Idan da'irar resistor da capacitor a bude suke a cikin da'irar sha zai haifar da jujjuyawar burr wutar lantarki nan take kuma ya ƙone thyristor.Dangane da gazawar wutar lantarki, muna amfani da tebur na WAN Xiu don auna absorpti akan juriya da ƙarfin ƙarfin abin sha, don sanin ko akwai kuskure a cikin kewayen juriya na juriya.

4.The load rage a cikin sulation na grou nd: rufi na load madauki ragewa, haifar da lodi zuwa wuta tsakanin ƙasa, tsoma baki tare da jawo lokaci na bugun jini ko forming wani babban ƙarfin lantarki a duka ƙarshen thyristor da kuma kona sinadarin thyristor.

5.Pulse jawo wutar lantarki: Idan bugun bugun jini ya ɓace ba zato ba tsammani lokacin da na'urar ke gudana, zai haifar da buɗaɗɗen kewayawa na inverter kuma ya haifar da babban ƙarfin lantarki a ƙarshen fitarwa na matsakaicin mitar wutar lantarki kuma ya ƙone sinadarin thyristor.Irin wannan kuskuren yawanci shine samuwar bugun bugun inverter da laifin da'irar fitarwa.Ana iya duba shi ta hanyar oscilloscope, kuma yana iya zama mummunar hulɗar wayar dalma ta inverter, kuma yana iya girgiza haɗin waya da hannu kuma ya sami matsayi mara kyau.

6.The kayan aiki yana buɗewa lokacin da nauyin ke gudana: Lokacin da na'urar ke gudana a babban iko, idan nauyin kwatsam ya kasance a cikin budewa, za a ƙone nau'in sarrafa silicon a ƙarshen fitarwa.

7.The load ne short circuited lokacin da kayan aiki ne a guje: Lokacin da kayan aiki ne a guje a babban iko, idan da load ba zato ba tsammani short circuited, shi zai yi babban gajeren kewaye halin yanzu tasiri a kan SCR: kuma idan a kan halin yanzu kariya mataki. ba za a iya karewa ba, za a ƙone abubuwan SCR.

8.Protection na tsarin gazawar (rashin kariya): Amintaccen SCR ya dogara da tsarin kariya.Idan akwai gazawa a cikin kariyar) akan tsarin, kayan aikin ba su da kyau a cikin aikin sa, wanda zai kawo rikicin zuwa amincin SCR.Saboda haka, yana da mahimmanci don duba tsarin kariya lokacin da SCR ya ƙone.

9.SCR sanyaya tsarin gazawar: Thyristor yana da zafi sosai a wurin aiki kuma yana buƙatar sanyaya don tabbatar da aikinsa na yau da kullun.Gabaɗaya, akwai hanyoyi guda biyu don kwantar da gyaran gyaran siliki mai sarrafa: ɗaya sanyaya ruwa, ɗayan kuma sanyaya iska.Ana amfani da sanyaya ruwa sosai, kuma ana amfani da sanyaya iska don samar da wutar lantarki ƙasa da 100KW.Yawancin lokaci, matsakaicin matsakaicin kayan aiki tare da sanyaya ruwa yana sanye da da'irar kariyar matsa lamba na ruwa, amma shine mahimmancin kariya ga duka tasirin.Idan an toshe wani ruwa, ba za a iya kiyaye shi ba.

10.The reactor is in problem: Internal ignition of the reactor yana sa curre nt side na in verier side ya katse.
