Furemu yekabati yekutanga yeswitchgear ine voltage shoma chimiro chekubatanidza chakabatanidzwa. Zvikamu zvese zvefuremu yekabati zvakagadzirwa ne galvanized, zvakabatana zvakasimba kuburikidza ne self-tapping locking screws kana 8.8 grade hexagonal screws kuti zvigadzire furemu yekabati yekutanga. Zvadaro, zvichienderana nezvinodiwa nekuchinja kwechirongwa, magonhi anoenderana, ma sealing plates, ma partitions, ma brackets ekuisa, mabhazi, ma functional units nezvimwe zvikamu zvinowedzerwa kuti zviunganidze switchgear yakazara ine voltage shoma. Zviyero zvezvikamu nezvikamu muswitchgear zvinogadziriswa (modulus unit E = 25mm, zvakafanana pazasi).
1. Nzvimbo yekugovera simba (inozonzi PC)
● Kabhineti yePC yakakamurwa kuita zvikamu zvina, zvinoti kamuri remabhazi rakatwasuka, riri kumashure kwekabhineti; Chikamu cheyuniti inoshanda chiri pamusoro pekabhineti kana kuruboshwe rwekabhineti; Chikamu chetambo, pasi pekabhineti kana kurudyi kwekabhineti: chikamu chedunhu rekudzora, pamusoro pekabhineti.
Matanho ekuparadzanisa: mapaneru e-melamine phenolic sandwich kana mapurati esimbi anoshandiswa pakati penzvimbo yemabhazi yakatambanudzwa nechikamu cheyuniti inoshanda. Chikamu chedunhu rekudzora nechikamu cheyuniti inoshanda zvinoparadzaniswa neganda rechisimbiso chepurasitiki chinodzorwa nemoto. Chikamu cheyuniti inoshanda kuruboshwe nechikamu chemagetsi chiri kurudyi zvinoparadzaniswa neplate yesimbi.
● Makabati anopwanya macircuit breakers akaiswa mukabati anogona kushandiswa nemaoko kunze kwekabati kana gonhi rakavharwa. Tarisa mamiriro ekuvhurwa nekuvharwa kwecircuit breaker uye ona kana circuit breaker iri panzvimbo yekuyedza kana kuti iri panzvimbo yekushanda zvichienderana nehukama huripo pakati penzira yekushanda negonhi.
● Dunhu guru nedunhu rekubatsira zvakagadzirwa sechimiro chekuparadzanisa. Mayuniti edunhu rekubatsira akagadzirwa nemidziyo, marambi ezviratidzo uye mabhatani ese akaiswa pabhodhi repurasitiki. Kune chifukidziro chakagadzirwa nepurasitiki yepolyurethane foam inodzivirira moto iri kumashure kwebhodhi. Yakasiyana nedunhu guru.
2.Ine nzvimbo yekudzora mota inodhonzwa uye nzvimbo yekugovera simba remagetsi mashoma (inozonzi neMCC inodhonzwa)
● Kabhineti yeMCC inodhonzwa yakakamurwa kuita makamuri matatu ekuparadzanisa, kureva, kamuri rebhazi rakatwasuka riri kumashure kwekabhineti, kamuri reyuniti inoshanda riri kuruboshwe rwemberi kwekabhineti, uye kamuri retambo riri kurudyi rwemberi kwekabhineti. Kabhineti yakatwasuka nekamuri reyuniti inoshanda zvakaparadzaniswa nemadziro anoshanda akagadzirwa nepurasitiki yefoam inodzivirira moto, uye kamuri retambo rakaparadzaniswa neplate yesimbi kubva kukamuri rebhazi rakatwasuka nekamuri reyuniti inoshanda.
●MCC inobviswa ine maumbirwo maviri: kushanda kwedivi rimwe chete uye kushanda kwemativi maviri.
● MCC inobviswa ine saizi shanu dzakajairwa dzemadhirowa, idzo dzinoti 8E/4,8E/2,8E,16E uye 24E zvakateerana. Maumbirwo emadhirowa e8E/4 ne8E/2 zvikamu zvepurasitiki zvinodzivirira moto uye mapurofayi ealuminium alloy (4 zvikamu zve8E/4 kana 2 zvikamu zve8E/2 zvichigadzira nzvimbo ye8E-height). Kureba kwese kwechikamu cheyuniti inoshanda i72E.
● Madhirowa mashanu akajairika anowanzova nematafura gumi nematanhatu ekuparadzanisa anotungamira kunze. Kana zvichidikanwa, kunze kwedhirowa re8E/4, mamwe madhirowa mana anogona kuwedzerwa kusvika pa32. Materu etafura yega yega yakagadziriswa anogona kubatanidzwa netambo nhatu panguva imwe chete. Materu ari pamusoro apa anopiwa nemugadziri ane zvishongedzo zvakakodzera uye mapini anoputira anotonhora nechigadzirwa.
● Kuburikidza nekushanda kwemudziyo wekubatanidza michina, dhirowa rinogona kutamiswa chete kana dunhu guru nedunhu rekubatsira zvese zvabviswa. Mudziyo wekubatanidza michina unoita kuti dhirowa rive nenzvimbo yekufamba, nzvimbo yekutyoka nenzvimbo yekuparadzanisa, uye rinozvimaka nezviratidzo zvinoenderana.
Mubato wekushandisa uri pachishandiso chekubatanidza michina pamwe nemubato wekushandisa wechikamu chikuru chemagetsi zvinogona kuvharwa nemakiyi matatu panguva imwe chete.
3. Nzvimbo yekudzora mota inofambiswa uye nzvimbo diki yekugovera simba remagetsi (inozonzi inofambiswa MCC)
● Hunhu hwemaumbirwo ekabhineti yeMCC inofambiswa hwakafanana ne(a) uye(b) muchikamu 4.2.
● Chishandiso chekushandisa chakagadzirwa sechimiro chinofambiswa. Kubatana kuripo pakati pechishandiso chekushandisa nebhawa remagetsi rinomira kunoshandisa nzira yekutanga yekubatanidza. Kunyangwe kana dunhu rakabatana naro riri mupenyu, chishandiso chekushandisa chinogona kubviswa zvachose kubva mumidziyo yodzoserwa kumashure. Chimwe mugumo chimiro chakasimba.
Mayuniti anoshanda eMCC inofambiswa akakamurwa kuita 3E, 6E, 8E, 16E, 24E uye 40E functional unit compartments, uye kukwirira kwese kuri 72E.
4. Sisitimu yebhazi
● Bhara remabhazi rakatambanudzwa (L1,L2,L3). Bhara remabhazi rakatambanudzwa rakaiswa muchikamu chebhara remabhazi chakazvimirira chiri kuseri kwekabati. Rine nzvimbo mbiri dzekuisa dzakasarudzika, ndiko kuti, 1/3 kana 2/3 yekukwirira kwekabati. Bhara remabhazi rinogona kuiswa pamusoro kana pasi sezvinodiwa, mapoka epamusoro neapasi anogonawo kuiswa panguva imwe chete. Maseti maviri emabhazi anogona kushandiswa zvakasiyana kana zvakaenzana.
Bhasi rechikamu chimwe nechimwe rine mabhazi maviri, mana kana masere akabatana zvakafanana, uye zvikamu zvebhazi zvine mhando nhanhatu dze10x30x2,10x60×2,10x80x2,10×60x4,10x80x2x2 uye 10×60x4×2.
● Bhasi rebhazi rakamira rakaita seL rine bhazi remhangura re50x30x5, iro rakaiswa mumadziro anoshanda akagadzirwa nepurasitiki inodzivirira moto, uye dziviriro yechikamu chiri kurarama inosvika IPp20.
● Waya isina kusimba (N wire) uye waya yekudzivirira pasi (PE wire). Waya isina kusimba newaya yekudzivirira pasi inoiswa pamwe chete pachikamu chezasi cheyuniti inoshanda uye yakatwasuka muchikamu chetambo. Kana waya yeN nePE wire zvakaparadzaniswa neinsulator, waya yeN nePE wire zvinoshandiswa zvakasiyana. Kana zviviri izvi zvikapfupikiswa neconductors, waya yePEN inogadzirwa.
5.Sisitimu yekudzivirira pasi
Dunhu rekudzivirira re switchgear iyi rine zvikamu zviviri: waya yePE (kana PEN) yakaiswa yoga uye inomhanya nehurefu hwese hwegadziriro uye zvikamu zvesimbi zvinofambisa mhepo. Kunze kwemusuwo wekunze neplate yekuvharira, zvimwe zvikamu zvesimbi zvakagadzirwa nematini. Kubatana kwechivakwa kwakagadzirwa nokungwarira kuti kukwanise kupfuura nemhepo pfupi.
6.Treyi yetambo yedunhu rekubatsira
Tireyi yetambo yedunhu rekubatsira yakaiswa pamusoro pechikamu cheyuniti inoshanda, uye tambo dzinobatanidza makabati netambo dzemagetsi dzeveruzhinji dzinogona kuiswa mutireyi.
7. Matanho ekuparadzanisa ematunhu ekubatsira
Mudunhu rega rega rechirongwa cheMCC chinobviswa, transformer inopatsanura inogona kuiswa zvichienderana nezvinodiwa nesystem. Kugona kwetransformer kwakakwira kupfuura kweAC contactor, uye zvinodiwa zvinotsanangurwa.
