Kana iyo system software ikakundikana, iyo yakajairika kukanganisa zvikamu zvinodzivirira chimiro, uye wedunhu anotyora anoshandisa iyo yakajairika kukanganisa kuramba rwendo, iyo iri padhuze yedunhu breaker ye substation ichadzivirira rwendo zvinoenderana neyakajairwa kukanganisa zvikamu.Kana mamiriro asingatenderi, chiteshi chekuchengetedza chinogona zvakare kushandiswa kuita kure kure redunhu breaker rwendo panguva imwe chete.Iyo wiring nzira inonzi circuit breaker common fault protection.
Kazhinji kutaura, mushure mekufamba kwechikamu chezvino zvikamu, 2 mapoka eanomhanya anobatanidza anotorwa uye akabatanidzwa munhevedzano nekunze posture kudzivirira majoini, uyezve iyo yakajairika chengetedzo yemhosva inoitiswa munzira.
Chii chinoitwa nedunhu rebreaker?
Circuit breaker anonyanya kushandiswa mumamotor, hombe nzvimbo inoshandura uye nzvimbo dzekuparadzira dzinowanzo bvisa mitoro.Iyo yedunhu inotyora ine basa rekutyora kuchengetedza tsaona mutoro, uye inoshanda pamwe neyakasiyana relay dziviriro kuchengetedza michina yemagetsi kana nzira.
Iyo yedunhu breaker inowanzo shandiswa kune chikamu cheyakadzika-voltage mwenje yekutyaira simba, uye inogona kudzima otomatiki dunhu;iyo yedunhu inotyora inewo akati wandei mabasa akadai semutoro uye pfupi-yedunhu chengetedzo yekukanganisa, asi kana paine dambudziko nemutoro uri pazasi, unofanirwa kuchengetedzwa.basa, uye kuparara kwevoltage yecircuit breaker haina kukwana.
Nhasi kune basa rinoshanda rinoputika nekudzivirira, rinobatanidza mabasa emagetsi emagetsi uye high-voltage disconnector.Iyo inoshanda yedunhu breaker ine dziviriro inogona zvakare kushandiswa seyemunhu muviri wakakwira-voltage isolation switch.Muchokwadi, yakakwira-voltage yekuparadzanisa switch kazhinji haigone kushandirwa nemutoro, asi maseketi anotyora ane mabasa ekudzivirira akadai sepfupi-yedunhu kukanganisa, kudzivirira mutoro, uye under-voltage dziviriro.
Inotsanangura kushanda musimboti wedunhu mabreaker zvakadzama
Basic Type: Chishandiso chiri nyore chekudzivirira chedunhu ifuse.Fuse ingori tambo yakatetepa, ine sheath yekudzivirira, iyo inobva yabatanidzwa kudunhu.Mushure mokunge dunhu radzimwa, zvose zvino zvinofanira kupfuura nefuse, uye ikozvino yefuse yakafanana neyozvino yemamwe mapeji padunhu rimwe chete.Rudzi urwu rwefiyuzi rakagadzirirwa kuti rirambe rakavhurika kana tembiricha yakadzika yasvika pane imwe nhanho.Mafusi akakuvadzwa anogona zvakare kutungamira nzira dzekudzivirira yakawandisa ikozvino kubva mukukuvadza imba wiring.Dambudziko nefuse nderekuti inongova nemhedzisiro imwe chete.Nguva dzose fuse payakakuvadzwa, inofanira kutsiviwa neimwe itsva.A circuit breaker anogona kuita basa rimwechete se fuse, asi rinogona kushandiswazve kakawanda.Chero bedzi iyo yazvino inosvika padanho rine njodzi, ichangotungamira nzira.
Nheyo yekutanga: Waya mhenyu uye waya isina kwayakarerekera mudunhu yakabatana nemativi ese emagetsi switch.Kana bhatani riri munzvimbo yakabatana, yazvino inoburitswa kubva pazasi terminal mudziyo, ichitevedzana ichiyerera kuburikidza neelectromagnetic, inofamba AC contactor, iyo static data AC contactor, uye pakupedzisira inoburitswa kubva kumusoro terminal michina.Magetsi azvino anogona kuve magineti emagetsi.Simba remagineti rinogadzirwa nemagetsi rinowedzera neazvino.Kana ikozvino yakaderedzwa, simba remagineti richaperawo simba.Kana yazvino ichisvetukira kune ine njodzi kugona, iyo electromagnetic induction pfungwa inogadzira simba remagineti rakasimba zvakakwana kufambisa tsvimbo yesimbi yakabatana kune simba switch yekubatanidza.Izvi zvichaita kuti nhare AC contactor skew uye kusiya static data AC contactor, kuvhura redunhu.Ikozvino inovhiringwawo.Pfeka-resistant simbi mitsetse yakagadzirwa maererano neiyo imwechete musimboti.Kusiyana neChirungu, haidi kupa iyo electromagnet kinetic simba, asi panzvimbo iyoyo inobvumira simbi tambo kuti ikotame pasi peiyo yakakwira ikozvino, iyo inomhanyisa kubatana.Mamwe mabreaker edunhu anofambisa switch yemagetsi zvichienderana nekuchaja kwezvinoputika.Kana yazvino ikadarika imwe nhanho, inobatidza zvinopfuta uye zvinoputika mbishi, yobva yasundidzira tsvimbo yepiston kudzvanya switch.
Yakanatsiridzwa: Iwo akanyanya kusimukira anotyora matunhu anosarudza kusiya midziyo yemagetsi yakapusa uye kushandisa zvemagetsi (semiconductor indasitiri) kuona mazinga aripo.Ground Fault Interrupter (GFCI) Iyi imhando nyowani yedunhu rinotyora.Aya mabheji ematunhu haangodzivisi kukanganisa kweimba wiring, asiwo anodzivirira vanhu kubva kune electrocution.
Enhanced musimboti: Iyo GFCI icharamba ichiona iripo mune isina kwayakarerekera uye mhenyu waya mudunhu.Kana zvese zvanaka, mafungu ari mumaseketi maviri anofanirwa kunge akafanana.Kana iyo mhenyu isina kwayakarerekera yadzika pasi nekukasira (semuenzaniso, vamwe vanhu netsaona vanobata iyo mhenyu isina kwayakarerekera), iyo iripo mune mhenyu yakarerekera inongoerekana yawedzera, asi isina kwayakarerekera haizodaro.Kana iyo GFCI ikaona chinhu chakadaro, inobva yadimbura dunhu kuti idzivirire electrocution.GFCIs haifanirwe kumirira kusvika ikozvino yakwira kusvika kumazinga ane njodzi, saka chiyero chavo chekupindura chinomhanya zvakanyanya kupfuura zvakajairwa matunhu edunhu.
