1. Yawanci
Overcurrent shine lamarin kuskure mafi yawan lokuta a cikin masu sauya mitar. Akwai dalilai da yawa waɗanda zasu iya haifar da wuce gona da iri a cikin masu sauya mitar, kuma mafi yawanci shine nauyi. Ana iya rarraba kurakuran da ke faruwa cikin yanayi kamar haka:
1. Lokacin da aka sake kunnawa, idan mai sauya saurin ya yi tafiya da zaran ya yi sauri, yana nuna cewa abin da ke faruwa yana da tsanani sosai, yawanci yakan haifar da gajeriyar da'ira, kayan aikin injiniya, lalacewar inverter module, ko ƙananan karfin juyi.
2. Bayan an kunna shi, yana tafiya, wanda yawanci ba za a iya sake saita shi ba. Babban dalili shi ne cewa da'irar actuation da na'urar ganowa na yanzu sun lalace.
3. Lokacin sake farawa, ba ya tafiya nan da nan, amma a lokacin hanzari. Babban dalili na iya zama cewa an saita lokacin haɓakawa gajarta sosai, ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙa'idodi suke.
2. Overvoltage
1. Ƙararrawar ƙararrawa yawanci yana faruwa yayin rufewa, kuma babban dalili na iya kasancewa lokacin ragewa ya yi gajeru sosai ko kuma akwai matsaloli tare da na'urar birki da na'urar birki.
2. Idan akwai birki naúrar a cikin mitar Converter da kuma wani birki resistor an haɗa zuwa waje na mitar Converter, idan har yanzu abin mamaki na "OU" faruwa a lokacin da deceleration aiwatar da mitar Converter, shi ya kamata ya zama saboda gazawar don saita makamashi amfani birkin zabi sigogi, rashin dace zabi na braking resistor juriya darajar, ko da braking naúrar ba aiki. A wannan lokacin, ana iya bincika yanayin dumama na resistor don tantancewa.
3. Idan akwai na'urar birki da birki da aka haɗa waje da mai sauya mitar, al'amarin "OU" yana faruwa ne yayin aikin rage saurin mitar. Yana iya yiwuwa wurin gano “OU” na mai sauya mitar ya yi ƙasa da wurin aiki na sashin birki. A wannan yanayin, yakamata a gyara wurin aiki na naúrar birki, ko kuma a daidaita ma'aunin kariya na "OU" na mai sauya mitar.
3. Rashin wutar lantarki
Ƙarƙashin wutar lantarki yana faruwa ne ta hanyar babban ƙarfin lantarki da yake ƙasa da ƙasa, wanda zai iya zama saboda asarar lokaci na wutar lantarki, bude da'irar a daya hannun gada na rectifier circuit, lalacewa ga ciki halin yanzu iyakance sauyawa kewaye (ba zai iya takaice-kewaye da halin yanzu iyakance resistor a lokacin al'ada aiki, haifar da wani babban ƙarfin lantarki drop a fadin resistor da kuma haifar da ƙarfin lantarki da za a aika zuwa ga inverter kewaye don zama ma low irin ƙarfin lantarki da za a iya samu a waje matsaloli);
1. Lalacewa ga ɗaya daga cikin gadoji masu gyara ko rashin aiki mara kyau na thyristors uku na iya haifar da kurakuran ƙarancin wuta;
2. Babban mai tuntuɓar da'ira ya lalace ko babban mai ba da izini ko lambar sadarwa ba ya shiga saboda lamuran kewaye. Rashin wutar lantarki na bas ɗin DC na iya haifar da rashin ƙarfi a kan na'urar caji.
3. Wutar gano wutar lantarki ta lalace, wanda ya haifar da matsalolin rashin ƙarfi.
4. Yawan zafi
Yin zafi fiye da kima laifi ne na yau da kullun na masu sauya mitar, wanda ƙila ya zama sanadin matsanancin zafin jiki, tsayawar masu sanyaya, na'urori masu auna zafin jiki, ko zazzafar mota.
1. Yanayin da ke kewaye ya yi yawa, musamman a lokacin rani. Don tallafawa abokan ciniki, ana shigar da mai sauya mitar sau da yawa a cikin majalisar kulawa. Idan yanayin sanyaya na majalisar kulawa ba zai iya cika buƙatun ba, zai haifar da zafin jiki a cikin ma'aikatun kulawa ya yi yawa kuma "mai zafi".
2. Axial flow fan yana makale ko baya gudu.
5. Rashin daidaituwa irin ƙarfin lantarki
Rashin daidaiton ƙarfin fitarwa yana bayyana gabaɗaya azaman saurin motsi da girgiza, kuma manyan dalilai na iya zama:
1. The inverter module ya karye, haifar da rashin daidaito uku-lokaci fitarwa ƙarfin lantarki;
2. Wutar lantarki na mai sauya mitar ta lalace, yana haifar da rashin daidaituwa a cikin ƙarfin fitarwa na matakai uku;
3. Mai amfani da fitarwa ya lalace, yana haifar da motar da ke gudana a cikin asarar lokaci;
4. Mummunan lamba na kebul na fitarwa wani lokaci yana haifar da asarar lokaci a cikin motar;
6. Yawan wuce gona da iri
Yin nauyi laifi ne na kowa, kuma idan an yi nauyi, ya kamata a fara bincikar ko nauyin mota ne ko kuma jujjuyawar mita. Gabaɗaya, saboda ƙarfin juzu'i mai ƙarfi na injin, in dai an saita sigogin mai sauya mitar yadda ya kamata, injin ɗin ba ya yin nauyi cikin sauƙi; Don ƙararrawar jujjuyawar mai jujjuyawar mitar, ya zama dole a duba ko ƙarfin fitarwa na mai sauya mitar al'ada ce.
