Nhanganyaya pfupi yeSwitchgear

Switchgear rudzi rwemidziyo yemagetsi, kunze kweswitchgear kunotanga kwapinda muswitch huru yekudzora mukabati, uye kwozopinda muswitch yesub-control, uye sub-circuit yega yega inoiswa zvichienderana nezvinodiwa zvayo.
Zvakaita semidziyo, otomatiki kudzora, mota magnetic switch, marudzi ese eAC contactors, mamwe akaiswawo mukamuri ine kumanikidzwa kwakanyanya uye kabhineti ine kumanikidzwa kwakaderera, ine mabhazi ane kumanikidzwa kwakakwira, senge magwenya emagetsi, mamwe akaiswawo kuchengetedza michina mikuru yekuderedza mutoro wevhiki.
Basa guru rekabhineti remaswitch nderekuvhura nekuvhara, kudzora nekudzivirira michina yemagetsi panguva yekugadzira, kutumira, kugovera uye kushandura simba remagetsi.
Zvinhu zviri mukabati kemaswitch zvinonyanya kusanganisira circuit breaker, disconnecting switch, load switch, operating mechanism, mutual inductor nezvimwe zvakasiyana-siyana zvekudzivirira.
Kune nzira dzakawanda dzekuisa switchgear muzvikamu, dzakadai sekuti circuit breaker inogona kukamurwa kuita switchgear inofamba uye switchgear yakagadziriswa;
Kana zvichienderana nechimiro chakasiyana chekabhineti, inogona kukamurwa kuita kabhineti ine switch yakavhurika, kabhineti ine switch yakavharika yesimbi, uye kabhineti ine switch yakavharika yesimbi;
Zvichienderana nemazinga akasiyana emagetsi, switchgear inogona kukamurwa kuita switchgear ine voltage yakakwira, switchgear yepakati nepakati uye switchgear ine voltage yakaderera.
Inonyanya kushanda kumafekitori emagetsi, zviteshi zvemagetsi, petrochemical, metallurgical steel rolling, machira eindasitiri yechiedza, mafekitori nemabhizinesi emigodhi nenzvimbo dzekugara, zvivakwa zvirefu nezvimwe zviitiko zvakasiyana.

A. "Dziviriro shanu" yeHigh Voltage Switchgear

1. Mushure mekunge trolley ye vacuum circuit breaker iri mu high voltage switch cabinet yavhara panzvimbo yekuyedza, trolley circuit breaker haigone kupinda munzvimbo yekushanda. (Dzivirira kuvhara nekuremerwa)

2. Kana banga rekugadzika riri mukabhineti remagetsi ane simba rakawanda riri panzvimbo yaro, chinopwanya dunhu remota hachigone kupinda nekuvharika. (Dzivirira waya yekugadzika kuti isavhare)

3. Kana muchina wekuvhura circuit wevacuum uri mukabati kekuchinja magetsi ane simba rakawanda uchishanda pakuvharwa, gonhi rekumashure rekabati rinokiyiwa nemuchina uri pabanga rekudzika. (Kudzivirira kutsauka kwepakati pemagetsi).

4. Muchina wekupwanya circuit wevacuum uri mu "high voltage switch cabinet" unovhara panguva yekushanda, uye banga rekupwanya harigone kuiswa. (Dzivirira kuti tambo yekupwanya isaturikwe kana iri kushanda)

5. Chinopwanya dunhu chevacuum chiri mukabhineti yekuchinja magetsi akawanda hachigone kubuda panzvimbo yekushanda kwechikamu chemotokari chevacuum kana chichishanda. (Dzivirira kudhonza bhureki nemutoro)

B. Kupatsanura
Yakarongwa nekirasi yemagetsi

Zvichienderana nehurongwa hwe voltage level, AC1000V ne dziri pasi dzinowanzonzi low-voltage switchgear (senge PGL, GGD, GCK, GBD, MNS, nezvimwewo), uye AC1000V ne dziri pamusoro dzinonzi high-voltage switchgear (senge GG-1A, XGN15, KYN48, nezvimwewo). Dzimwe nguva voltage iri mu high voltage cabinet inonzi AC10kV inonzi medium voltage cabinet (senge XGN15 10kV ring network cabinet).

C. Yakarongwa nemagetsi emagetsi

Yakakamurwa kuita: AC switch cabinet, DC switch cabinet.

D. Yakarongwa zvichienderana nemaumbirwo emukati

Chishandiso chekubvisa (senge GCS, GCK, MNS, nezvimwewo), chishandiso chekuchinja chakagadzirwa (senge GGD, nezvimwewo)

E. Nekushandisa

Kabhineti yemitsetse inouya, kabhineti yemitsetse inobuda, kabhineti yekuyera, kabhineti yemuripo (capacitor cabinet), kabhineti yekona, kabhineti yebhazi.

Maitiro ekushanda
A. Maitiro ekutumira simba

1. Isa chivharo chekumashure kutanga, wobva wavhara gonhi repamberi.
2. Shandisa spindle yeground switch woivhura.
3. Sundidzira mota yemaoko (iri muchimiro chebhureki rakavhurika) mukabati (nzvimbo yekuedza) nemota yekufambisa (mota yepuratifomu).
4. Isa chivharo chechipiri musoketi isingachinji (chiratidzo chekuyera nzvimbo chakabatidzwa), vhara gonhi repakati repamberi.
5. Sunda ngoro yemaoko kubva panzvimbo yekuyedza (yakavhurika) kuenda panzvimbo yekushanda nemubato (chiratidzo chenzvimbo yekushanda chakabatidzwa, chiratidzo chenzvimbo yekuyedza chakadzima).
6. Mota yekuvhara circuit breaker.

B. Kukundikana kwemagetsi (kugadzirisa) Maitiro
1 Vhura mota yemagetsi inopwanya macircuit.
Buda mumota yemaoko kubva panzvimbo yekushanda (yakavhurika brake) uchienda panzvimbo yekuedza neruoko.
3 (chiratidzo chenzvimbo yekushanda chadzimwa, chiratidzo chenzvimbo yekuedza chabatidzwa).
4 Vhura gonhi repakati repamberi.
5 Dhonza chivharo chechipiri kubva musokisi isingachinji (chinongedzo chekuyedza nzvimbo chakadzima).
6. Buda mumota yemaoko (iri pachena) kubva mukabati ine mota yekufambisa.
7. Shandisa spindle yeground switch woiita kuti ivhare.
8. Vhura ndiro yekuvharira yekumashure uye gonhi repamberi rezasi.

Kutarisa nekudzivirira kuchengetedzeka
Kuburikidza neongororo dzakasiyana-siyana dzekuongorora chiedza, hunhu hwemukati mearc arc hunoonekwa.
Pahwaro uhwu, sensor ye optical fiber pamwe nemudziyo wekudzivirira uye wekuchengetedza we multi-point internal fault arc detection unogadzirwa uchishandisa arc single criterion rule.
Chishandiso ichi chine mabhenefiti ekuva nechimiro chiri nyore, mutengo wakaderera, nguva yekukurumidza kushanda uye kugona kwakasimba kwekudzivirira kukanganiswa.
Hazvingogone kushandiswa chete, asiwo zvinogona kubatanidzwa nemidziyo yakasiyana-siyana yekudzivirira marelay, kuitira kuti mutengo wekabhineti yeswitch usakwire, hunyanzvi hwepamusoro uye kukosha kwakawedzerwa zvivandudzwe zvikuru.
