GBT 18487.1-2015 inotsanangura izwi rekuti residual current protector sezvinotevera: Residual current protector (RCD) is mechanical switchgear kana musanganiswa wemidziyo yemagetsi inogona kubatika, kutakura uye kutyora yazvino pasi pemamiriro ekushanda akajairwa, pamwe nekubvisa vanobatika kana. iyo yakasara ikozvino inosvika pamutengo wakatarwa.Iyo mechanic switchgear kana musanganiswa wemidziyo yemagetsi inogona kubatika, kutakura uye kutyora ikozvino pasi peyakajairwa mamiriro ekushanda uye inogona kutyora anobatika kana yasara ikozvino yasvika kukosha kwakatarwa pasi pemamiriro akatarwa.
Mhando dzakasiyana dzeanosara anodzivirira aripo kune akasiyana edziviriro mamiriro uye akakodzera mhando yekusara yazvino chengetedzo inofanirwa kusarudzwa kuitira kuti mamiriro acho adzivirirwe.
Zvinoenderana neyakajairwa kupatsanurwa kwezvakasara zvazvino zvine DC chikamu chekuita maitiro, vasara vadziviriri vemazuva ano vanonyanya kukamurwa kuita AC mhando yasara inodzivirira ikozvino, A mhando yasara inodzivirira ikozvino, F mhando inosara yezvino dziviriro uye B mhando yasara inodzivirira ikozvino.Basa ravo rakasiyana rakadai.
AC mhando yakasara inodzivirira ikozvino: sinusoidal AC yakasara ikozvino.
Type A yasara inodzivirira ikozvino: AC rudzi basa, pulsating DC yasara ikozvino, pulsating DC yasara ikozvino yakasimudzwa pa 6mA yeakatsetseka DC ikozvino.
Type F inosara inodzivirira ikozvino: Rudzi rweA, musanganiswa wasara ikozvino kubva kumasekete anofambiswa nechikamu uye asina kwaakarerekera kana nhanho uye pasi epakati conductor, achipurudzira DC yakasara ikozvino yakasimudzwa pane yakatsetseka DC ikozvino ye10mA.
Type B yasara inodzivirira ikozvino: Type F, sinusoidal AC yasara ikozvino pa1000Hz uye pazasi, AC yakasara ikozvino yakamisikidzwa pane 0.4 nguva yakayerwa yasara chiitiko chazvino kana 10mA yakatsetseka DC yazvino (chero yakakura), ichipurudzira DC yakasara ikozvino yakamisikidzwa pa0. rated residual action current kana 10mA smooth DC current (chero ipi yakakura), DC inosara iripo kubva kumaseketi akagadziridzwa, yakatsetseka DC yasara ikozvino.
Mavakirwo ekutanga eEV on-board charger kazhinji anosanganisira EMI kusefa kwechikamu chekuisa, kugadzirisa uye PFC, simba rekushandura redunhu, EMI sefa yechikamu chekubuda, nezvimwe. Bhokisi dzvuku mumufananidzo uri pazasi rinoratidza maviri-nhanho simba chinhu. gadziriso yedunhu ine yekuzviparadzanisa transformer, uko Lg1, lg2 uye anobatsira capacitors anoumba yekuisa EMI sefa, L1, C1, D1, C3, Q5 inoumba nhanho-up mhando Iyo yekumberi nhanho PFC dunhu, Q1, Q2, Q3, Q4, T1 , D2, D3, D4, D5 inoumba simba rekushandura redunhu remashure, Lg3, lg4 uye anobatsira capacitors anoumba inobuda EMI sefa kuderedza ripple kukosha.
Munguva yekushandiswa kwemotokari, pachange paine mabhampa uye kuzununguka, kuchembera kwechishandiso uye mamwe matambudziko anogona kuita kuti kuvharirwa mukati mejaja yemotokari kuve nedambudziko, zvekuti kune charger yemotokari muAC yekuchaja maitiro munzvimbo dzakasiyana dzekutadza modhi yekuongorora. inogona kuwanikwa sezvinotevera kukundikana modes.
(1) chikanganiso chepasi padivi re AC remunisiparati network yekuisa, panguva iyo iko kukanganisa ikozvino iindasitiri frequency AC ikozvino.
(2) Ground kukanganisa muchikamu chekugadzirisa, uko iko kutadza kuri kupuruzira DC ikozvino.
(3) DC / DC pasi kukanganisa kumativi ose maviri, apo kukanganisa ikozvino kwakatsetseka DC ikozvino.
(4) yekuzviparadzanisa transformer pasi kukanganisa, kukanganisa ikozvino isiri-frequency AC ikozvino.
Kubva kune A mhando yakasara yekudzivirira yekudzivirira basa inogona kuzivikanwa, inogona kuchengetedza iyo AC mhando basa, pulsating DC yasara ikozvino, pulsating DC yasara yazvino yakakwira isingasviki 6mA yakatsetseka DC yazvino, uye mota charger DC kukanganisa ikozvino ≥ 6mA, A mhando. akasara anodzivirira anogona kuoneka hysteresis kana kusaita, zvichikonzera basa rakajairwa, ipapo anosara anodzivirira anorasikirwa nebasa rekudzivirira.
Iyo yeEuropean standard IEC 61851 haitendi Type B, asi kune maEVSE ane Type A asara edziviriro azvino, zvinodikanwa kuti uwedzere kuona kuti dunhu rine mhosva ine DC inodarika 6mA inogurwa, imwe kana imwe.Yakasanganiswa nekuongororwa kweiyo pamusoro yasara yazvino yekudzivirira kusarudzwa, zviri pachena kuti kana iyo iri pamusoro chengetedzo yekukanganisa ichizosangana, kubva pakuchengetedza nzvimbo yekuona, mhando B inosara inodzivirira ikozvino inodiwa.
