Chimiro
Ichi chigadzirwa chakakamurwa kuita zvikamu zviviri: kabati uye VCB. Kabati inogadzirwa nesimbi yakakotama ndiro uye yakaunganidzwa nemabhaudhi mushure mekupfapfaidza. Zvinoenderana nemaitiro ekushanda, inogona kukamurwa kuita zvikamu zvina: kamuri diki rebhazi, relay chiridzwa kamuri, VCB kamuri, tambo yekamuri uye bhazi kamuri, chikamu chimwe nechimwe chinoparadzaniswa neyakagadzika simbi kupatsanura. Dhigirii rekudzivirira reiyo switchgear yakavharirwa ndeye IP4X; kana gonhi rekamuri reVCB richivhurwa, dhigirii rekudzivirira iIP2X.
Iyo switchgear ine makuru edunhu zvirongwa senge tambo yekupinza uye yekubuda, pamusoro pekupinda nekubuda, bhazi rekubatanidza, kubviswa, voltage transformer, uye mheni inosunga. Iyo bhasibha inotora kusungirirwa kwemusanganiswa, uye iyo yepakati-chikamu uye zvibatanidza zvakashongedzerwa nemaoko ekudzivirira akagadzirwa nezvinhu zvinodzoreredza moto. Makabati ari padyo nebhasibar makuru anoparadzaniswa nemaoko ebhasi, izvo zvinogona kudzivirira njodzi kuti isapararire uye kutamba basa rekubatsira rebhasi bar. Imba yetambo yakashongedzerwa nepasi switch, overvoltage yekudzivirira mudziyo, nezvimwe.
Kune simbi yekuchengetedza shutter pamberi pebhokisi rekusangana. Ivhavha yevhavha yepamusoro nechepazasi inovhurwa otomatiki kana VCB ichibva padanho rekudimbura/kuyedzwa ichienda kunzvimbo yekushanda, uye yobva yavharwa otomatiki apo VCB inofamba ichienda kune rumwe rutivi, ichinyatso bvisa kubva pamhepo yakakwira. Iyo inopindirana pakati peiyo main switch, VCB, pasi switch uye kabati gonhi rinotora inosungirwa michina yekubatanidza nzira yekusangana ne "shanu kudzivirira" kushanda zvinodiwa.
Iyo yedunhu breaker inotora screw rod drive propulsion mechanism uye overrunning clutch. Iyo screw rod nut feed mechanism inogona kushandiswa zviri nyore kufambisa VCB pakati penzvimbo yekuyedza nenzvimbo yekushanda. Nerubatsiro rwekuzvivharira pfuma ye screw rod nut, VCB inogona kuvharwa yakavimbika munzvimbo yekushanda kudzivirira VCB kubva pangozi inokonzerwa nekutiza nekuda kwesimba remagetsi. Iyo overrunning clutch inoshanda kana VCB ichidzokera kunzvimbo yekuyedza uye kana yasvika panzvimbo yekushanda. Inoita kuti shaft yekushanda uye screw shaft isununguke uye isina basa, iyo inogona kudzivirira misoperation uye kukuvadza nzira yekudya. Mamwe maVCB anoshandisa lever feed mechanism. Nzvimbo yebasa rekuedza yakavharwa nekuisa pini.

Zvakanakira: compact chimiro, yakanaka zvinhu, yakachengeteka kushanda, nyore kushanda, yakagadzikana kushanda, yakavimbika kukiya
Ichi chigadzirwa chakakamurwa kuita kabati uye handcart. Muviri wekhabhineti wakagadzirwa nesimbi yakabhenda ndiro uye inounganidzwa nemabhaudhi mushure mekupfapfaidza. Zvinoenderana nemaitiro ebasa, inogona kukamurwa kuita zvikamu zvina: kamuri diki rebhazi, relay mudziyo kamuri, handcat room, cable room uye bhazi kamuri, uye chikamu chimwe nechimwe chakaparadzaniswa neyakaiswa simbi kupatsanura. Kirasi yekudzivirira yekabati shell ndeye IP4X; Musuwo wechikamu chengoro yemaoko unovhurwa uye nhanho yekudzivirira ndeye IP2X. Iyo switchgear ine main circuit scheme ye cable inlet uye outlet line, overhead inlet uye outlet line, busbar connection, isolation, voltage transformer, lightning arrester, nezvimwewo maoko akagadzirwa nezvinhu zvinodzoreredza moto nekuumba jekiseni. Makabati ari padyo nebhawa guru rebhazi anoparadzaniswa nebhazi bhasi, izvo zvinogona kudzivirira kupararira kwetsaona uye kutamba basa rekubatsira rekutsigira bhawa guru rebhazi. Iyo cable room ine pasi switch uye overvoltage yekudzivirira mudziyo. Ivhavha yesimbi yakaiswa pamberi pebhokisi rekusangana. Ivhavhavha yekumusoro nechepazasi inovhurika otomatiki kana mota yemaoko inofamba kubva pakudimbura/kuyedzwa chinzvimbo ichienda kunzvimbo yekushanda, uye inovhara otomatiki kana mota yemaoko inofamba ichienda kune rumwe rutivi, ichinyatsoitsaura kubva pakumanikidzwa kukuru. Iyo inopindirana pakati peiyo main switch, iyo handcar, yepasi switch uye gonhi rekabati rinotora inosungirwa mekiniki yekuvhara maitiro kusangana ne "shanu kudzivirira" basa rinodiwa. Circuit breaker ruoko mota inotora screw drive propulsion mechanism, overrunning clutch. Iyo screw nut propulsion mechanism inogona kushanda zviri nyore kufambisa ngoro yemaoko pakati penzvimbo yekuyedza nenzvimbo yekushanda, uye iyo yekuzvivharira pfuma ye screw nut inogona kuita kuti handcart ivharwe zvakavimbika munzvimbo yekushanda kudzivirira tsaona yakakonzerwa nekuita kwe. simba remagetsi. Iyo overpass yakakwirira yekuvhara inoshanda kana mota yemaoko ichidzoserwa kunzvimbo yekuyedza uye kune chinzvimbo chekushanda, kuitira kuti shaft yekushandisa uye lead screw shaft inovharika otomatiki uye idling, izvo zvinogona kudzivirira misoperation uye kukuvadza propulsion mechanism. Dzimwe mota dzemaoko dzinoshandisa lever propulsion mechanisms. Nzvimbo yekushanda yekuedza ine nzvimbo uye kuvhara.
