KYN61-40.5 mhando yesimbi-yakavharwa inobviswa mhando AC simbi-yakavharirwa switchgear (inozonzi "switchgear") inonyanya kuratidzwa nekushandiswa kweZN85-40.5 yakazara insulated vacuum circuit breakers uye chitubu chinoshanda masisitimu mukhabhati, uye iyo cabinet body inounganidzwa nepurasitiki yakavharwa simbi, iyo inovandudza kuenderana chaiko kweVCB uye kabati. Iyo VCB iri nyore kusunda nekudhonza kunze uye ine kuchinjika kwakasimba nechitarisiko chakanaka, mhinduro dzakakwana, kushandiswa kwakachengeteka uye kwakavimbika.
Ichi chigadzirwa chinoshandiswa mu35kV matatu-chikamu AC 50Hz simba system. Inoshandiswa kugashira uye kugovera simba remagetsi muzvidyarwa zvemagetsi, zviteshi uye makamuri ekugovera magetsi emaindasitiri nemabhizimusi emigodhi. Iine kutonga, kudzivirira uye kutarisa mabasa. Ichi chigadzirwa chinoenderana nezviyero: GB3906 "Alternating-yazvino simbi-yakavharirwa switchgear uye controlgear yeyakayerwa voltage pamusoro pe3.6kV uye kusvika uye inosanganisira 40.5kV", GB/T11022 "Yakajairwa yakatarwa ye-high-voltage switchgear uye controlgear zviyero", DL/ T404 "Alternating-current metal-enclosed switchgear and controlgear for rated voltages above 3.6kV and up to and including 40.5kV", IEC60298 "AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52kV".

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" zvinoshanda 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.
