1. Ana nuna kuskuren bayanin kuskuren lokaci-ɗaya ko kuskuren multi-phase azaman "inveter u" ko "inveter v or w". Dalili kuwa shi ne, inverter na lokaci-lokaci ko multi-phase ya gaza. Idan mafi girman halin yanzu na bututun sauya shine i> 3inrms, inrms shine igbt. Wannan yanayin zai faru idan akwai matsala tare da rated halin yanzu na inverter, ko kuma akwai wani abu da ba daidai ba tare da taimakon wutar lantarki na lokaci daya na ƙofar inverter. Bayan irin wannan kuskuren ya faru, yana iya haifar da ɗan gajeren kewayawa a ƙarshen abin da ake fitarwa na mitar, ko kuma yana iya sa motar ta yi rawar jiki sosai saboda saitunan mai sarrafawa ba daidai ba. Gabaɗaya akwai yanayi guda biyu yayin kulawa:
(1) Rashin gazawar hukumar Lokacin da Siemens inverter yayi gyaran gyare-gyaren bugun jini, ana tsara zagayowar aikin jerin bugun jini bisa ga dokar sinusoidal. Motsin motsin motsin sine ne, kuma kalaman mai ɗauka shine bipolar isosceles triangle wave. Matsakanin mahaɗar igiyoyin daidaitawa da igiyar ɗaukar kaya suna ƙayyade jerin bugun jini na inverter gada fitarwa lokaci ƙarfin lantarki. Ƙofar sarrafa kofa tana samuwa ta hanyar babban haɗin IC (ASIC), wanda ya haɗa da na'ura mai mahimmanci na dijital tare da ƙuduri har zuwa 0.001hz da matsakaicin mita na 500hz da kuma na'urar bugun jini mai faɗi wanda ke haifar da igiyoyin sine mai matakai uku. tsarin. Wannan Modulator yana aiki da asynchronously a mitar bugun jini akai-akai na 8khz. Wutar wutar lantarki da yake haifarwa ta hanyar kunnawa da kashe na'urorin wutar lantarki guda biyu a hannun gada ɗaya. Idan wannan allon kewayawa ya gaza, to ba za ta iya samar da wutar lantarki ba kamar yadda aka saba, kuma ana bukatar a canza allon da gyara.
2 Rashin lalacewar na'urar inverter Na'urar inverter da aka yi amfani da ita a cikin Siemens inverter transistor ne da aka keɓe gate bipolar transistor – igbt. Halayen sarrafa shi sune babban shigarwar shigarwa da ƙananan ƙofa na yanzu, don haka ikon tuƙi ƙarami ne kuma yana iya aiki kawai a cikin yanayin sauyawa. Ba za a iya aiki a cikin girman yanayi ba. Mitar jujjuyawar sa na iya kaiwa ga girma sosai, amma aikin sa na antistatic ba shi da kyau. Ko bangaren igbt yayi kuskure ana iya auna shi da ohmmeter. Takamaiman matakan sune kamar haka:
● Cire haɗin wutar lantarki na mai sauya mita;
● Cire haɗin motar da aka sarrafa;
●Yi amfani da ohmmeter don auna maƙasudin tashar fitarwa da tashoshin haɗin DC a da d (duba hoton da aka makala). Auna kowane gwaji sau biyu ta hanyar canza polarity na ohmmeter. Idan igbt na mai sauya mitar ya kasance daidai, ya kamata ya kasance: daga u2 zuwa a ƙananan juriya, in ba haka ba, yana da tsayin daka; daga u2 zuwa d, yana da tsayin daka; in ba haka ba, yana da ƙananan juriya. Haka yake ga sauran matakai. Lokacin da aka cire haɗin igbt, yana da ƙimar juriya mai girma duka sau biyu, kuma idan gajere ne, yana da ƙarancin juriya.

3 Rashin rashin ƙarfi na amfani da makamashi Saƙon kuskure ana nuna shi azaman “pulsed resistor”, ma'ana mai jujjuyawar wutar lantarki yayi yawa. Akwai dalilai guda uku: ƙarfin ƙarfin birki na sabuntawa ya yi yawa, ƙarfin birki ya yi yawa ko kuma lokacin birki ya yi gajere. Resistor mai amfani da makamashi ƙarin abu ne. Tun da nauyin kayan yadi da kayan fiber na sinadarai babban nauyin inertia ne, babban bututu mai sauyawa da ƙarfin amfani da makamashi suna haɗuwa a layi daya zuwa ɓangaren DC na mai jujjuya mitar zuwa DA wiring. Babban aikinsa shi ne haɗa wutar lantarki Tasirin iyakance yawan ƙarfin wuta akan layin da lokacin kunnawa, kashewa ko lodawa. Amma lokacin da ƙarfin birki ya wuce ƙimar ƙima, za a katse aikin. Gabaɗaya akwai yanayi guda biyu:
(1) Rashin ƙarfi mai amfani da makamashi. A cikin ainihin mitar mai canzawa, mai jujjuya bugun jini shine 7.5ω/30kw. Bayan amfani da inverter tsawon shekaru da yawa, saboda yawan farawa da tsayawa na inverter, resistor ya yi zafi kuma juriyarsa ta ragu. Koyaya, Siemens inverters suna da takamaiman buƙatu akan ƙimar juriya, wanda ake buƙata ya zama mafi girma ko daidai da 7.5ω. Saboda haka, ko da yake juriya na ƙarfin amfani da wutar lantarki na wannan inverter yana da kusan 7.1ω, laifin da ke sama zai faru kuma ba zai iya farawa kullum ba. Daga baya, na canza zuwa babban mai ƙarfi mai ƙarfi tare da ƙimar juriya na kusan 8ω kafin in kunna shi.
(2) gazawar igbt. Akwai kuskure a sashin igbt na inverter, wanda ke haifar da wuce gona da iri na sake fasalin halin yanzu kuma yana haifar da gazawar juzu'i na resistor yawan kuzari.
4. Laifin zafin zafi Ana nuna saƙon kuskure a matsayin "sama da zafin jiki" saboda zafin zafi na inverter ya yi yawa. Dumama mai sauya mitar yana faruwa ne ta hanyar na'urar inverter. Na'urar inverter kuma ita ce mafi mahimmanci kuma mai rauni na mai sauya mitar, don haka ana sanya na'urar firikwensin zafin jiki (ntc) da ake amfani da ita don auna zafin jiki a saman ɓangaren na'urar inverter. Lokacin da zafin jiki ya wuce 60 ℃, mai jujjuya mitar zai fara ƙararrawa ta hanyar isar da sigina; lokacin da ya kai 70 ℃, mai sauya mitar zai tsaya kai tsaye don kare kansa. Yawancin zafi yana haifar da yanayi guda biyar:
(1) Yanayin zafin jiki yana da girma. Wasu wuraren bita suna da yanayin zafi mai girma kuma sun yi nisa da dakin sarrafawa. Domin adana igiyoyi da sauƙaƙe aiki a wurin, dole ne a shigar da inverter akan wurin a cikin taron bitar. A wannan lokacin, zaku iya ƙara bututun iska mai sanyi zuwa mashigar iska na mai sauya mitar don taimakawa wajen watsar da zafi.
(2) Fassarawar fan. Mai shayewar mai jujjuya mitar ita ce motar 24v DC. Idan abin ɗaukar fanfo ya lalace ko naɗaɗɗen ya ƙone kuma fanfon ɗin bai juya ba, zai sa mai sauya mitar yayi zafi.
(3) Ruwan zafi ya yi datti sosai. Akwai na'urar kawar da zafi na aluminium a bayan mai jujjuyawar mitar. Bayan gudu na dogon lokaci, waje za a rufe shi da ƙura saboda wutar lantarki mai mahimmanci, yana tasiri sosai ga tasirin radiator. Saboda haka, wajibi ne a tsaftacewa da tsaftacewa akai-akai.
(4) lodin kaya. Nauyin da mai sauya mitar ke ɗauka yana ɗaukar nauyi na dogon lokaci, yana haifar da zafi. A wannan lokacin, duba wutar lantarki
