Huru kurongeka uye zvigadzirwa zvechigadzirwa cheyakaderera-voltage circuit breakers (air switches)

Main classification uye zvigadzirwa zvemhando yakaderera-voltage circuit breakers (ma switch emhepo)

Iyo huru yekuisa nzira yeyakaderera-voltage yedunhu mabreaker, zvichienderana nechimiro chavo chechimiro, yakavhurika uye mhando yemidziyo, inova yakajairika chigadzirwa kupatsanura. Vhura inonziwo furemu rudzi kana universal type, nepo mhando yemidziyo inonzi plastic shell type.

General kusarudzwa musimboti wedunhu mabreaker.

Iyo yakarongerwa kushanda kwemagetsi emagetsi emagetsi emagetsi anofanira kunge akakura kudarika kana akaenzana nemagetsi emagetsi emutsara. Ikozvino yakarongerwa yemhepo inoputika inofanira kuva yakakura kudarika kana kuenzana nemutoro wezvino wemutsara.Iyo inonzi short-circuit breaker power of the circuit breaker inofanira kuva yakakura kudarika kana yakaenzana nepamusoro-soro pfupi-circuit current inogona kuitika pamutsara (yakaverengwa seyakakosha kukosha) . 1.25 nguva yakagadziriswa ikozvino yekusunungurwa kwepakarepo kwemhepo inoputika.Iyo yakagadziriswa yevheji yekusunungurwa kwepasi pemhepo inoputika inofanira kuenzana nemagetsi emagetsi emutsara.Iyo inonzi voltage ye shunt release of the circuit breaker inofanira kuenzana nekugadzirisa simba rekugadzirisa magetsi.Iyo yakarongerwa kushandiswa kwemagetsi emagetsi emagetsi emagetsi inofanira kuenzana nemagetsi ekugadzirisa magetsi emagetsi ekugadzirisa magetsi. Mimwe mienzaniso yemagetsi emagetsi anongobvumira mutsara kupinda kubva kumusoro, asi mamwe maenzanisi anobvumira mutsara kupinda kubva kumusoro kana pasi.

Nheyo dzekusarudza low-voltage circuit breakers

1.Tsvaga rudzi uye fomu yekudzivirira yedunhu rinoputika maererano nezvinodiwa zvekudzivirira mutsara: sarudza furemu yemhando, mhando yemidziyo kana yezvino yekumisa mhando, nezvimwe.
Equipment type circuit breaker: Iyo ine insulating epurasitiki shell, yakavakirwa-mukati yekusangana system, arc yekudzima kamuri uye kuburitsa, nezvimwewo, uye inogona kuvharwa nemaoko kana nemagetsi (yehombe-inopaza maseketi mabreak). Iyo ine simba rekupwanya rakasimba, yakanyanya kusimba kugadzikana, uye yakanyatso kusarudzwa kuchengetedza mabasa. Inoshandiswa zvakanyanya mumitsara yekugovera. Parizvino, zvigadzirwa zvinowanzo shandiswa zvinosanganisira DZ15, DZ20, DZX19, C45N (ikozvino yakakwidziridzwa kuC65N) uye mamwe akateedzana. Pakati pavo, C45N (C65N) madhiraivha edunhu ane zvakanakira saizi diki, yakasimba yekutyora simba, yakanaka yazvino yekumisikidza kuita, mashandiro ari nyore, uye mhando dzakakwana uye zvakatemwa. Zvinogona kusanganiswa nyore nyore kuita maviri-pole, matatu-pole uye mana-pole matanda edunhu akavakirwa pane imwechete-pole chimiro, uye anoshandiswa zvakanyanya mumatavi ekuvhenekesa evagari uye mitsara yemapazi e60A uye pazasi (inonyanya kushandiswa kunopinda mutsetse switch yevashandisi vekugara uye kuvhenekesa bazi rinochinja munzvimbo dzekutenga).
2.Frame-mhando yakaderera-voltage circuit breakers: yakakura simba, yakasimba pfupi-circuit breaking capacity, high dynamic stability, inokodzera AC 50Hz, rated voltage 380V distribution network, sechidziviriro chikuru chekugovera hunde mitsetse. Frame-type circuit breakers inonyanya kuumbwa necontact system, operating mechanism, overcurrent release, shunt release, undervoltage release, accessories uye furemu, nezvimwe. Parizvino, anowanzo shandiswa furemu-mhando yakaderera-voltage dunhu mabreak munyika yangu ndeye DW15, ME, AE, AH uye mamwe akatevedzana. Iyo DW15 yakatevedzana mabreaker breakers anogadzirwa uye anogadzirwa munyika yangu. Iwo akazara akateedzana anosanganisira akati wandei mamodheru akadai se1000, 1500, 2500, uye 4000A. Iwo ME, AE, uye AH akatevedzana maseketi mabreaker anogadzirwa pachishandiswa tekinoroji inotengeswa kunze kwenyika, iine zvirevo zvakakwana uye mamodheru (Ini ndinochinja nhanho dzazvino kubva pa630A kuenda pa5000A, huwandu hwegumi nematatu mazinga), uye iyo yakatemerwa yekutyora kwesimba yakasimba kupfuura iyo yeDW15. Vanowanzo shandiswa pakudzivirira kukuru kwepasi-voltage kugovera trunks.
3.Intelligent circuit breakers: Parizvino, kune marudzi maviri emagetsi akangwara anogadzirwa munyika yangu: furemu rudzi uye plastiki shell. Frame type yakangwara yedunhu mabreaker anonyanya kushandiswa semakuru edunhu mabhureki ehungwaru otomatiki kugovera masisitimu, nepo epurasitiki goko rehungwaru redunhu mabreaker anonyanya kushandiswa kugovera magetsi mukugovera network uye kutonga nekudzivirira mitsara uye magetsi ekushandisa. Inoshandiswa sekutonga kwematatu-phase cage asynchronous motors. Hunhu hweakangwara edunhu mabreaks ndeokuti vanoshandisa akangwara controller (akangwara rwendo midziyo) ine microprocessors kana single-chip microcomputers semusimboti, uye vane mabasa ekutarisa pamhepo, otomatiki kugadzirisa, kuyerwa, kuyedza, kuzviongorora, kutaurirana, nezvimwe parameters kana dunhu redziviriro riri kuita, uye chengetedza ma paramita aya mundangariro isiri-inotenderera yemubvunzo. Akajairika mudzimba akangwara edunhu breaker modhi anosanganisira DW45, DW40, DW914 (AH), DW18 (AE-S), DW48, DW19 (3WE), DW17 (ME), nezvimwe.

Paunenge uchisarudza wedunhu redunhu, zvinotevera zvinofanirwa kutariswa:

1. Iyo yakatemerwa voltage (UN) yedunhu rebreaker inofanirwa kuenzana kana yakakura kupfuura yakayerwa voltage yemutsara wakachengetedzwa.
2. Iyo yakayerwa voltage yekuburitswa kwedunhu rebreaker's undervoltage inofanirwa kuenderana neyakayerwa voltage yetambo yakachengetedzwa.
3. Iyo yakarongerwa ikozvino yedunhu rinoputika uye kuburitswa kwayo kwepamusoro kunofanirwa kunge kwakakura kupfuura kana kuenzana neyakaverengerwa ikozvino yedunhu rakachengetedzwa.
4. Mhedzisiro yekupwanya simba remutsigiri wedunhu inofanira kudarika kukosha kunobudirira kwepamusoro pfupi-yekutenderera ikozvino mumutsara.
5. Maitiro ekudzivirira ekumusoro uye epasi edunhu anotyora mutsetse wekugovera anofanirwa kurongeka, neakadzika-chikamu chekudzivirira maitiro akaiswa pazasi uye kwete kupindirana neapamusoro-chikamu chekudzivirira maitiro.
6. Iko kunonoka kwenguva refu kutsika ikozvino kwedunhu rinopwanya kunofanirwa kunge kuri kushoma pane inobvumidzwa inoenderera ikozvino yewaya.

Kune magetsi ekugovera maseketi mabreaker, zvinotevera sarudzo dzinoshanda:

1. Kurongeka kwekukosha kwemuvharidzi wenguva yakareba yekushanda ikozvino haifaniri kudarika inobvumirwa kutakura kukwanisa kwetambo. Pamashandisirwo ewaya netambo, zvinokurudzirwa kushandisa 80% yewaya uye tambo inotenderwa kutakura ikozvino.
2. Iyo inodzoserwa nguva yetatu-nguva-yakareba kunonoka kushanda ikozvino kukosha kwekugadzirisa kunofanirwa kunge kwakakura kudarika kana kuenzana nenguva yekutanga yemota ine huwandu hwekutanga ikozvino mumutsara.
3. Iko ipapo ipapo kukosha kwekugadzika kunofanirwa kuve kanenge ka1.1 chiyero chemutsetse wekuverenga mutoro ikozvino (Ijx) uye chigadzirwa chemotor kutanga ikozvino kukanganisa coefficient (k1, kazhinji 1.7-2), mota inotanga ikozvino yakawanda (k), uye yakayerwa ikozvino yemota hombe (Icdm).

Kune mota dziviriro dzedunhu mabreaker, anotevera esarudzo misimboti anoshanda:

1. Iko kunonoka kwenguva refu ikozvino kugadzika kukosha kunofanirwa kuenzana neiyo mota yakayerwa ikozvino.
2. Iyo yekumisikidza yekumisikidza ikozvino yeanopwanya edunhu anodzivirira cage motors anofanirwa kunge ari 8-15 nguva iyo mota yakayerwa ikozvino, nepo yeronda rotor motors, inofanirwa kuita 3-6 nguva iyo mota yakayerwa ikozvino.
3. Iyo nguva inodzoserwa yekatanhatu-yakareba kunonoka iko kukosha kwazvino kunonoka kunofanirwa kunge kwakakura kupfuura kana kuenzana nenguva chaiyo yekutanga mota, ine sarudzo dze1S, 3S, 5S, 8S, 12S, kana 15S zvichienderana nehuremu hwemutoro pakutanga.

Paunenge uchibatanidza mabreaker breakers uye fuse, zvinotevera zvinofanirwa kutariswa:

1. Kana iyo inotarisirwa ipfupi-yedunhu ikozvino panzvimbo yekumisikidza iri ishoma pane yedunhu redhiza yekupwanya kugona, fuse inogona kushandiswa sekuchengetedza kuchengetedza nekuda kwesimba rayo rakatemerwa pfupi-yedunhu rekutyora kugona. Sezvinoratidzwa muMufananidzo 1, hunhu hwefiyusi yekuchengeta (1) inopindirana nehunhu hweanotyora wedunhu (2). Muchiitiko chemutsetse wepfupi-dunhu, nguva yekupwanya yefuse ipfupi pane yedunhu redunhu, kuve nechokwadi chekuchengetedzwa kwedunhu. Iyo yekuchinjisa poindi pahunhu inogona kusarudzwa pa80% yedunhu redunhu rakayerwa pfupi-yedunhu kutyora kugona.
2. Iyo fuse inofanirwa kuiswa padivi remagetsi redunhu rinotyora kuti ive nechokwadi chekushandisa zvakachengeteka.
