Chikamu cheApplication
GGD AC low-voltage power distribution cabinet inokodzera vashandisi vemagetsi semagetsi, zviteshi, maindasitiri ezvemaindasitiri uye vamwe vashandisi vemagetsi seAC 50HZ, yakayereswa kushanda voltage 380V, yakayerwa ikozvino kusvika 3150A simba rekugovera sisitimu sesimba, mwenje uye magetsi ekushandura magetsi. , Kugovera uye kutonga.Chigadzirwa chacho chine yakakwirira yekutyora simba, yakayerwa pfupi-nguva inomira ikozvino kusvika ku50KAa, inochinjika yedunhu chirongwa, yakanakira musanganiswa, yakasimba kuita, uye novel chimiro.Ichi chigadzirwa ndechimwe chezvinomiririra zvigadzirwa zveyakaungana uye yakagadziriswa panel switchgear munyika yangu.
Ichi chigadzirwa chinoenderana neIEC439 "Low-Voltage Switchgear uye Control Equipment", GB7251.12-2013 "Low-Voltage Switchgear uye Kudzora Equipment Chikamu 2: Yakakwana Simba Shanduko uye Kudzora Equipment" uye mamwe maitiro.
GGD AC low-voltage power distribution cabinet inokodzera vashandisi vemagetsi semagetsi, zviteshi, maindasitiri ezvemaindasitiri uye vamwe vashandisi vemagetsi seAC 50HZ, yakayereswa kushanda voltage 380V, yakayerwa ikozvino kusvika 3150A simba rekugovera sisitimu sesimba, mwenje uye magetsi ekushandura magetsi. , Kugovera uye kutonga.
Environmental Conditions
1. Tembiricha yemhepo yakadzika haina kupfuura +40℃uye kwete pasi pe -5℃.Avhareji tembiricha mukati maawa makumi maviri nemana haifaniri kunge yakakwira kupfuura +35℃.
2. Kuiswa kwemukati uye kushandiswa, kukwirira kwenzvimbo yekushandiswa hakufaniri kudarika 2000m.
3. Hunyoro hunyoro hwemhepo yakapoteredza haipfuuri 50% kana tembiricha yepamusoro iri +40℃, uye hunyoro hwepamusoro hunobvumirwa pane tembiricha yakaderera: (semuenzaniso, 90% pa +20℃), zvinofanirwa kutariswa kuti tembiricha inogona kuchinja Tsaona inokanganisa condensation.
4. Kana iyo midziyo yakaiswa, kurerekera kubva kune yakamira ndege haifanirwe kudarika 5°.
5. Zvishandiso zvinofanira kuiswa munzvimbo dzisina kuzununguka kwakanyanya uye kukanganisa, uye nzvimbo iyo zvikamu zvemagetsi hazvina kusvibiswa.
6. Kana mushandisi ane zvakakosha zvinodiwa, zvinogona kugadziriswa kuburikidza nekubvunzana nemugadziri.
Muenzaniso uye Zvaunoreva
Iyo Main Technical Parameters
1. Mamiriro emagetsi ekutanga anoratidzwa muTafura 1

2. Mubatsiri wedunhu chirongwa
Dhizaini yedunhu rekubatsira yakakamurwa kuita zvikamu zviviri: chirongwa chemagetsi uye chirongwa chekudyara simba.
3. Bhazi guru
Kana iyo yakayerwa ikozvino iri 1500A uye pazasi, bhazi rimwe chete rebhuronzi rinoshandiswa.Kana iyo yakayerwa ikozvino yakakura kupfuura 1500A, bhazi rebhuronzi rinoshandiswa.Iyo inopindirana pamusoro pemabhasibars zvese zvinogadziriswa nemarata.
4. Kusarudzwa kwezvikamu zvemagetsi
a.Iyo GGD cabinet inonyanya kutora zvimwe zvemagetsi zvemberi zvinogona kugadzirwa-zhinji muChina.Zvakadai seDW17, DZ20, DW15, nezvimwe.
b.Iyo 1ID13BX uye HS13BX inotenderedzwa nebanga maswichi zvikamu zvakakosha zvakagadzirirwa neNLS kuti zvizadzise zvinodiwa zveyakasiyana chimiro cheGGD cabinet.Inoshandura maitiro ekushanda kwemaitiro uye inochengetedza zvakanakira zvigadzirwa zvekare.Iro rudzi rutsva runoshanda rwechikamu chemagetsi.
c.Semuyenzaniso, kana dhipatimendi redhizaini richisarudza zvinhu zvitsva zvemagetsi zvine mashandiro ari nani uye tekinoroji yepamusoro zvichienderana nezvinodiwa nemushandisi, nekuti GGD kabati ine yakanaka yekumisikidza inoshanduka, kazhinji haizokonzerese kugadzira uye kuisa kunetsa nekuda kwezvakagadziridzwa zvikamu zvemagetsi.
d.Kuti uenderere mberi nekuvandudza kugadzikana kwedunhu, rutsigiro rwebhazi rweGGD kabati rinotora yakatsaurirwa rudzi rweZMJ rwakasanganiswa bhasi rinosungirira uye insulating rutsigiro.Iyo busbar clamp yakagadzirwa nepamusoro-simba, yakakwira-inodzoreredza murazvo wePPO composite zvinhu, ine yakakwirira yekuvharisa simba, yakanaka yekuzvidzima kuita, uye yakasarudzika chimiro.Inogona kusanganiswa nyore nyore kuita imwe bhasibha kana kaviri bhasi bar clamp nekugadzirisa chivakwa chekuvaka.The insulating support is sleeve-type molded structure ine yakaderera mutengo uye yakakwirira simba, iyo inogadzirisa zvikanganiso zvekusakwana creepage kureba kwezvigadzirwa zvekare.
Odha Mirayiridzo
Paunenge uchiodha, mushandisi anofanira kupa inotevera data:
1. Muenzaniso wakazara wechigadzirwa (kusanganisira nhamba huru yechirongwa chedunhu uye nhamba yekubatsira yedunhu).
2. Iyo huru yedunhu system yekubatanidza sequence diagraph.
3. Electrical schematic diagram yedunhu rekubatsira.
4. Rondedzero yezvikamu mu cabinet.
5. Zvimwe zvinodiwa zvakakosha zvisingaenderane nemaitiro akajairika ekushandiswa kwechigadzirwa.
