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.
Ndeapi mabasa emagetsi emagetsi
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.
Ikozvino kune redunhu rinotyora rine basa rekuzviparadzanisa nevamwe, iro rinosanganisa mabasa eyakajairwa wedunhu breaker uye yekuzviparadzanisa switch.Iyo yedunhu inotyora ine basa rekuzviparadzanisa inogona zvakare kuve yekuzviparadzanisa yemuviri switch.Muchokwadi, iyo yekuzviparadzanisa switch kazhinji haigone kushandirwa nemutoro, nepo wedunhu rinopaza riine mabasa ekudzivirira akadai sepfupi redunhu, kuchengetedzwa 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.Fuse inoputika inogona kugadzira dunhu rakavhurika rinodzivirira yakawandisa ikozvino kubva mukukuvadza imba wiring.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 yazvino inosvika padanho rine njodzi, inogona kukasika kugadzira dunhu rakavhurika.
Basic kushanda musimboti: Iyo mhenyu waya mudunhu yakabatana kune ese magumo ekuchinja.Kana switch yaiswa munzvimbo yeON, 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 pane imwechete musimboti, mutsauko ndewekuti panzvimbo yekugonesa magineti emagetsi, mitsetse inotenderwa kukotama yega pasi peiyo yakakwira ikozvino, iyo inokonzeresa iyo linkage.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.
Yakavandudzwa kushanda musimboti: Iyo GFCI inogara ichitarisa iripo pane isina kwayakarerekera uye mhenyu waya mudunhu.Kana zvese zvanaka, ikozvino inofanira kunge yakafanana pawaya dzose.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.
