Ndeapi mabasa emagetsi emagetsi?Tsanangudzo yakadzama yemusimboti wekushanda wevanopwanya matunhu
Kana kukanganisa kukaitika muhurongwa, kuchengetedzwa kwechinhu chinokanganisa chinoshanda uye muparadzi wayo wedunhu akatadza kufamba, kuchengetedzwa kwechinhu chinokanganisa chinoshanda pane iri padhuze redunhu rinopaza chiteshi chekufamba, uye kana mamiriro achibvumidza, chiteshi chinogona inoshandiswa kugadzira madhigirii edunhu ane hukama pamagumo ari kure panguva imwe chete.Iyo yakapetwa wiring inonzi breaker failure protection.
Kazhinji, mushure mechikamu chezvino chinotongwa nekupatsanurwa kwechikamu chinoshanda, seti mbiri dzekutanga kutaurirana dzinobuda, dzakabatanidzwa munhevedzano nevekunze chiito chekudzivirira mabiti ekuchengetedza kutadza kwekutanga kana mutsara, tayi yebhazi kana chikamu chedunhu chinotyora.

Circuit breaker anonyanya kushandiswa mumamotor, makuru-capacity transformers uye substations anowanzo tyora mitoro.Iyo yedunhu inotyora ine basa rekutyora mutoro wetsaona, uye inobatirana neyakasiyana siyana relay dziviriro kuchengetedza midziyo yemagetsi kana mitsara.
Circuit breaker anowanzo shandiswa mukudzika-voltage mwenje uye zvikamu zvemagetsi, izvo zvinogona kudzima dunhu;mavhiriki edunhu anewo mabasa mazhinji akadai sekuremerwa uye kuchengetedzwa kwepfupi-yedunhu, asi kana paine dambudziko nemutoro kumucheto wezasi, kuchengetedza kunodiwa.Basa remutsigiri wedunhu, uye kureba kwecreepage yedunhu rinoputika harina kukwana.
Iye zvino pane dunhu redunhu rine ushamwari, iro rinosanganisira mabasa eiyo akajairwa cortaker uye yekuzviparadzanisa switch.Dunhu redunhu rine kusarudzika basa rinogona zvakare kuve rekuzviparadzanisa muviri.Muchokwadi, iyo yekuzviparadzanisa switch kazhinji haigone kushandirwa nemutoro, nepo wedunhu rinopaza riine mabasa ekudzivirira akadai sepfupi wedunhu, kudzivirira kwekuremerwa, undervoltage uye zvichingodaro.

Basic: Iyo yakapusa yekudzivirira yedunhu mudziyo ndiyo fuse.Fuse ingori waya yakaonda kwazvo, ine sheath yekudzivirira yakasungirirwa kudunhu.Kana dunhu rakavharwa, zvese zvino zvinofanirwa kuyerera kuburikidza nefuse - ikozvino pane fuse yakafanana neyezvino pane dzimwe nzvimbo padunhu rimwechete.Iyi fuse yakagadzirirwa kuvhuvhuta kana tembiricha yasvika pane imwe nhanho.Chipo chekuputika chinogona kugadzira dunhu rakavhurika iro rinodzivirira rakawandisa ikozvino kubva kukuvadza dzimba dzeimba.Dambudziko nefuse nderekuti inoshanda kamwe chete.Kana fuse ichiridzwa, inofanira kutsiviwa neimwe itsva.A circuit breaker anogona kuita basa rimwechete se fuse, asi rinogona kushandiswa kakawanda.Chero bedzi iyo iripo iripo inosvika padanho rine njodzi, inogona kubva padzimirisa pakarepo.
Basic kushanda musimboti: Iyo mhenyu waya mudunhu yakabatana kune ese magumo ekuchinja.Kana switch yaiswa mu ON state, ikozvino inoyerera ichibva pasi terminal, kuburikidza ne electromagnet, inofamba inobata, iyo static contactor, uye pakupedzisira yepamusoro terminal.Ikozvino inogona kuita magineti iyo electromagnet.Simba remaginiti rinogadzirwa neelectromagnetic rinowedzera sezvo ikozvino inowedzera, uye kana ikozvino ikadzikira, simba remagineti rinodzikira.Kana iyo yazvino ichisvetuka kusvika kumatanho ane njodzi, iyo electromagnet inogadzira yakakwana simba remagineti kudhonza tsvimbo yesimbi yakasungirirwa kune switch yekubatanidza.Izvi tilts ari kufamba contactor kure static contactor, kutyora redunhu.Ikozvino inovhiringwawo.Iyo dhizaini yebimetal mitsetse yakavakirwa pamusimboti mumwechete, mutsauko ndewekuti panzvimbo yekugonesa magineti emagetsi, mitsetse inotenderwa kukotama yega pasi peiyo yakakwira ikozvino, iyo inozoita kuti kubatanidza.Mamwe mabreaker edunhu anozadzwa nezvinoputika kuti abvise switch.Kana iyo yazvino ichipfuura imwe nhanho, zvinhu zvinoputika zvinobatidzwa, izvo zvinozoita kuti piston ivhure switch.
Yakanatsiridzwa: Madhiriki epamusoro epamusoro anobvisa zvishandiso zvemagetsi zvakapfava zvichifarira zvemagetsi (semiconductor zvishandiso) kutarisa mazinga aripo.A ground fault circuit interrupter (GFCI) rudzi rutsva rwedunhu rinotyora.Iri redunhu rinoputika haringodziviriri kukanganisa kune wiring mumba, asiwo inodzivirira vanhu kubva kumagetsi emagetsi.
Yakavharirwa basa rekushanda: Iyo GFCI inogara ichisaririra iyo yazvino pane yemasendimita uye yekurarama waya mudunhu.Kana zvese zvapora, izvo zvazvino zvinofanirwa kunge zvakaenzana pane zvese waya.Kana waya mhenyu ichinge yadzika pasi (sekunge mumwe munhu abata netsaona waya mhenyu), iyo iripo pawaya mhenyu inongoerekana yasvetuka, asi waya isina kwayakarerekera haizodaro.Iyo GFCI inobva yavhara dunhu payakaona mamiriro aya kudzivirira kukuvara kwemagetsi.Nekuti iyo GFCI haifanirwe kumirira yazvino kuti ikwire kusvika kune njodzi kuti itore danho, inobata nekukurumidza kupfuura echinyakare anotyora matunhu.
