Kumeneka Ibiriho Byerekeranye Nubu Byashizweho Binyuze Hagati Hagati Cyangwa Gukwirakwiza Ubuso hagati yibice byibyuma bitandukanijwe hagati yabyo, cyangwa hagati yibice bizima nibice bifatika, mugihe nta nenge ifite mugukoresha voltage.Muri Reta zunzubumwe za Amerika UL, Kumeneka Ibiriho Nubu Nibishobora Gukorwa Kuva Igice Cyibikoresho Byibikoresho byo murugo Harimo na Capacitive Coupling Current.Kumeneka bigizwe nibice bibiri, kimwe ni Imyitwarire Yubu I1 Binyuze Kurwanya Kurwanya;Ibindi Nugusimburwa Binyuze Mubushobozi Bwakwirakwijwe I2, Ubushobozi bwa Capacitive Reaction Yanyuma Ni XC = 1 / 2pfc Buringaniza Binyuranye na Frequency Frequency, Kandi Ubushobozi Bwagabanijwe Bwiyongera Nukwiyongera kwa Frequency, So Leakage Current Yiyongera hamwe no Kwiyongera kwingufu zinshuro.Kurugero: Gukoresha Thyristor Gutanga Imbaraga, Harmonic Yayo Uburemere bwumuraba byongera kumeneka.
Niba Porogaramu-Igenzurwa Kumeneka Ikizamini Kugenzura Kugenzura Imikorere Yumuzunguruko Cyangwa Sisitemu, Ibi Bikubiyemo Byose Binyura Mubikoresho Byibikoresho.
Mubyongeyeho Kuri Kugenda Kwinjira Kwisi (Cyangwa Igice Cyitwara Hanze Yumuzenguruko), Bikwiye kandi Gushyiramo Ibiri Kugenda Kwisi Kwisi Binyuze mubikoresho bya capacitif mumuzunguruko cyangwa sisitemu (Ubushobozi bwagabanijwe bushobora gufatwa nkibikoresho bifite ubushobozi).Ibyuma birebire bizagira uruhare runini rwo gukwirakwiza ubushobozi no kongera imyuka ivaho.Ibi bigomba kwitonderwa byumwihariko muri sisitemu idafite aho ihuriye.
Ihame ryo gupima ibimeneka bigezweho Nubusanzwe ni kimwe no gupima Kurwanya Kurwanya.Gupima Kurwanya Kurwanya Kurwanya Nukuri Mubyukuri Ubwoko Bumeneka Bugezweho, Ariko Byerekanwe Muburyo bwo Kurwanya.Nyamara, Igipimo gisanzwe cyo kumeneka kigezweho gikoresha itumanaho ryitumanaho, bityo ibimeneka byapimwe.
Ibiriho birimo Ibiro Byuzuye Ubushobozi.
Mugihe cyo Kwihanganira Kugenzura Umuvuduko, Kugirango Ukomeze Ibikoresho Byikigereranyo no Kugenzura Ibipimo bya Tekiniki Ukurikije Amategeko, Birakenewe kandi Kwemera ko Imbaraga Zumuriro Z’amashanyarazi Zitangiza Ibikoresho biri mu kizamini (Ibikoresho byo kubika) byemewe. Genda unyuze mubikoresho biri kugeragezwa (Ibikoresho byo kubika) * Agaciro kanini kagezweho, ubu bugezweho bwitwa Leakage Current, ariko ubu buryo bukoreshwa gusa murwego rwo hejuru Ibihe byihariye.Nyamuneka Mumenye Itandukaniro.
Porogaramu-Igenzurwa na Leakage Ikizamini Cyubu Mubyukuri Numuzunguruko w'amashanyarazi cyangwa ibikoresho bitembera mugice cya insulasiyo nta nenge na voltage ikoreshwa.
Ibiriho.Kubwibyo, Nibimwe Mubimenyetso Byingenzi Gupima Gukingira Ibikoresho Byamashanyarazi, Kandi Nibintu Byibanze Byerekana Ibikorwa Byumutekano wibicuruzwa.
Komeza Kumeneka Kugenda Kumwanya muto, Ufite Uruhare Rwingenzi mumikorere yumutekano wibicuruzwa byimbere.
Porogaramu ishobora kumeneka Ikizamini kigezweho ikoreshwa mugupima ibimeneka byubu ntaho bihuriye nigikorwa cyakozwe na Operation Amashanyarazi (Cyangwa Ibindi Bitanga Amashanyarazi) Yumuriro Wamashanyarazi Binyuze muri Insulation cyangwa Ikwirakwizwa rya Parameter Impedance, kandi Impedance Yinjiza Yigana Ingaruka Yumuntu Umubiri.
Kugenzura Ibiriho Byibanze Byibanze Byibanze Guhindura Impedance, Guhindura Urwego, Guhindura AC-DC, Kwaguka, Kwerekana Ibikoresho, nibindi. Muri Analog na Digital Ubwoko bubiri.
Ibyo bita Gukoraho Ibiriho, Muri make, Byerekeza kuri Ibiriho Bitemba Binyuze mu Cyuma Cyuma Cyuma Cyigikoresho Cyumubiri Binyuze mumubiri wumuntu kugeza kubice cyangwa igice gikoraho.Kubwibyo, Tugomba kuyikoresha mugihe dusuzumye uruziga rwumubiri wumubiri wumuntu, Voltmeter ibangikanye, hamwe numuzunguruko wumubiri wumuntu ufite imirongo itandukanye yo kwigana kumubiri wumuntu ukurikije amabwiriza atandukanye yumutekano wibicuruzwa.
Hariho Ubwoko Bune Bwamazi Yubu: Semiconductor Ibigize Kumeneka Ibiriho, Amashanyarazi Amashanyarazi Yubu, Umuyoboro wa Capacitor Umuyoboro na Akayunguruzo.
Izina ry'Ubushinwa: Ibimeneka bigezweho;Izina ryamahanga: Kumeneka kurubu
1 Kumeneka Ibiri muri Semiconductor
2 Amashanyarazi agezweho
3 Ubushobozi bwa Capacitor
4 Akayunguruzo Kumeneka
1. Kumeneka Ibiri muri Semiconductor
Gitoya Cyane Cyane Cyanyuze Muburyo bwa PN Iyo Buzimye.Iyo DS Yashyizwe Muburyo Bwimbere na GS Binyuranye Kubogama, Nyuma Umuyoboro Uyobora ufunguwe, Ibiriho bizatemba biva kuri D kugeza kuri S. Ariko Mubyukuri, Kubera kubaho kwa Electron yubusa, Electron yubusa ifatanye na SIO2 na N +, Bitera DS Kumena Ibiriho.
2. Amashanyarazi agezweho
Kugirango ugabanye imvururu muguhindura amashanyarazi, Ukurikije urwego rwigihugu, EMI Akayunguruzo kagomba gushyirwaho.Kuberako Ihuza ryumuzunguruko wa EMI, Hano harikintu gito kigezweho kubutaka nyuma yo guhinduranya amashanyarazi ahujwe no gutanga amashanyarazi, aribwo Amashanyarazi agezweho.Niba idafite ishingiro, Shell ya mudasobwa izaba ifite voltage ya 110 volt kugeza hasi, kandi izumva ituje iyo ikozweho nintoki, nayo izagira ingaruka kumikorere ya mudasobwa.
3. Ubushobozi bwa Capacitor
Ubushobozi bwa Capacitor ntibushobora kuba indashyikirwa mubitagenda neza.Iyo Capacitor ikoreshwa hamwe na DC ya voltage, Umuyoboro uzaba ufite imyuka igezweho.Niba Amashanyarazi agezweho ari manini cyane, Umuyoboro uzaba wangijwe nubushyuhe.Mubyongeyeho Kumashanyarazi ya Electrolytike, Kumeneka Kumurongo Wabandi Bashoboye ni Ntoya cyane, Parameter ya Insulation Resistance Parameter ikoreshwa kugirango yerekane imikorere yayo;Kandi Umuyoboro wa Electrolytike Ufite Umuyoboro Munini Usohora, Noneho Umuyoboro wa Leakage Ukoreshwa Kugaragaza Imikorere Yabwo (Bihwanye nubushobozi).
Koresha Inyongera DC ikoresha Umuvuduko Kuri Capacitor Izareba ko Kwishyuza Ibihe Byahindutse Byinshi, hanyuma bigabanuka hamwe nigihe.Iyo igeze ku gaciro kanyuma, Agaciro kanyuma kigezweho kageze kumiterere ihamye Yitwa Leakage Current.
Icya kane, Akayunguruzo Kumeneka Kugezweho
Igisobanuro cya Kumeneka Kugezweho Yumuriro Wamashanyarazi Akayunguruzo ni: Ibiriho Kuva Kurungurura Urubanza Kugeza ku iherezo ryitumanaho ryitumanaho ryinjira munsi yumurongo wongeyeho w'itumanaho.
Niba ibyambu byose byayunguruzo Byuzuye Byuzuye Biturutse kumyubakire, Agaciro ka Leakage Ibiriho Biterwa Byibanze Kumeneka Yubu ya Common-Mode Capacitor CY, Nukuvuga, Byibanze Biterwa nubushobozi bwa CY.
Kuberako Akayunguruzo Kasohoka Ibifitanye isano numutekano wumuntu ku giti cye, Ibihugu Byose Kwisi Bifite Amabwiriza akomeye kuri yo: Kuri 220V / 50Hz Itumanaho rya Gride Itanga Amashanyarazi, Kumeneka Kumurongo wurusaku rusabwa muri rusange birasabwa kuba munsi ya 1mA.
