General
ZS33 switchgear ine zvikamu zviviri: iyo yakavharirwa yakavharirwa uye chikamu chinobviswa ("Circuit breaker rori" kwenguva pfupi). Zvichienderana nemabasa emidziyo yemagetsi mukati mekhabhineti, switchgear inokamurwa kuita mana akasiyana anoshanda macompartments. Iyo yakavharidzirwa uye zvikamu zvinoparadzanisa zvikamu zvinoshanda zvinogadzirwa neAl-Zn-yakavharidzirwa mashizha esimbi, ayo akakomberedzwa uye akabatanidzwa pamwechete.
Zvikamu zvinobviswa zvinogona kusanganisira vacuum circuit breaker (VCB), SF6 circuit breaker, inogona kushanduka, mheni inosunga, insulator, fuse rori, etc. Mukati me switchgear, voltage presence indication unit (ichasarudzwa nemushandisi) inogona kuiswa. kutarisa mamiriro ekushanda kwedunhu rekutanga. Ichi chikamu chine zvikamu zviviri: "yakakwira-inogoneka sensor yakaiswa padivi pemutsetse wekudyisa uye chiratidzo chakaiswa pamusuwo wepasi-voltage compartment.
Iyo yekudzivirira giredhi reiyo switchgear yakavharirwa iIP4X, nepo iri IP2X apo redunhu redunhu rekamuri remukati rinovhurwa. Tichifunga nezvekukanganisa kwemukati kutadza arc pane chimiro cheZS33 switchgear, isu takaita yakasimba arc ignition bvunzo kuti ive nechokwadi chekuchengetedza kwevashandi nemidziyo.

Munzvimbo inopwanya dunhu, mune rori, uye njanji dzakagadzirirwa kufamba kubva murori. Rori inokwanisa kufamba pakati pe "sevhisi uye bvunzo / Dimbura" nzvimbo. Yakaiswa pamadziro ekumashure kwekamuri yerori, iyo shutter inogadzirwa nesimbi mahwendefa. Iyo shutter inovhurika otomatiki kana rori ichifamba kubva pa "Test/Disconnect* chinzvimbo ichienda ku "Service" chinzvimbo, nepo ichivharika otomatiki kana rori richifamba richienda kune rimwe divi, zvichidzivirira vashandi kuti vabate chero miviri ine magetsi.
Rori inogona kuvhiyiwa apo gonhi rakavharwa. Iwe unogona kuona nzvimbo yerori mukati mekhabhineti kuburikidza nehwindo rekuona, iyo mechanical Position inoratidzira yedunhu rinoputika, uye chiratidzo chekuchengetedza simba kana simba rekusunungura simba.
Kubatana pakati peyechipiri tambo ye switchgear uye yechipiri tambo yerori inowanikwa kuburikidza nebhuku rechipiri plug. Iwo anobatika anobatika eplug yechipiri akabatanidzwa kuburikidza nenaironi corrugated pombi, nepo yechipiri socket iri kurudyi pasi penzvimbo yedunhu. Chete kana rori yave mu "Test/Disconnect" chinzvimbo, ndipo panogona kubaiwa plug yechipiri kana kudhonzwa kubva pasocket. Kana rori iri munzvimbo ye "Sevhisi", iyo yechipiri plug yakavharwa uye haigone kuburitswa, nekuda kweiyo mechanic interlock. Rori redunhu rinotyora rinogona kungovhurwa nemaoko plug rechipiri risati rabatanidzwa kumusoro, asi haigone kuvharwa nemaoko nekuti yekuvhara yekuvhara magetsi yedunhu rebreaker rori haina simba.
Rori
Marata anotonhora anokungurutswa anogonya, anotengeswa, uye anounganidzwa kuti aite furemu yerori. Maererano nezvinangwa zvayo, rori yakakamurwa kuva mapoka akasiyana-siyana: rori inoputika, inogona kuchinja rori, rori yekuzviparadzanisa nevamwe, nezvimwewo, kureba nekudzika kwenzira imwe neimwe yakafanana, saka inoshandurana. Rori yedunhu inotyora ine "Sevhisi" uye "Muedzo/Disconnect" zvinzvimbo mukanzuru. Iyo yekukiyiwa unit inopihwa nechinzvimbo chega chega kuti ive nechokwadi chekuti mashandiro chaiwo anogona kuitwa chete kana rori iri munzvimbo chaiyo. Mamiriro ekubatanidza anofanirwa kuzadzikiswa rori isati yafambiswa, kuitira kuti uve nechokwadi chekuti chinotyora cheketi chinovhurwa rori risati rafambiswa.
Kana rori redunhu rinosundwa mukati me switchgear, iri mu "Test / Disconnect" chinzvimbo pakutanga, uyezve inogona kusundidzirwa munzvimbo ye "Sevhisi" nekutenderedza mubato.
Rori yedunhu inotyora inovakwa nearc interrupter uye maitiro ayo anoshanda. Dunhu redunhu rine matanda akazvimirira matatu-pase panoiswa maoko epamusoro uye epasi ekubatana kwepetal-like contacts. Iyo yechipiri tambo yemuchina wekushandisa inotadzikwa kuburikidza neyakakosha yechipiri yekubatanidza.
Nzvimbo yerori mukati mekhabhineti haingoratidzwi chete nechiratidzo chenzvimbo pane yakaderera voltage compartment panel asi zvakare inoonekwa nepahwindo rekuona pamusuwo. Iyo yekushandisa michina uye yekuvhara / yekuvhura chiratidzo chemutsigiri wedunhu inowanikwa pane yerori pani.
