Mtundu wa GCS low-voltage draw-out switchgear
Switchgear yamtundu wa GCS low-voltage draw-out switchgear idapangidwa ndikupangidwa ndi magulu awiri olumikizana ogwirizana malinga ndi zomwe akuluakulu akumakampani amafunikira, ambiri ogwiritsa ntchito mphamvu ndi magawo opanga.Otsika-voteji m'zigawo switchgear mogwirizana ndi zikhalidwe za dziko, ali apamwamba zizindikiro ntchito luso, akhoza kusintha ndi zosowa za msika mphamvu ndipo akhoza kupikisana ndi zinthu zomwe zilipo kunja, ndi mtundu GCS otsika-voteji m'zigawo switchgear wakhala. amagwiritsidwa ntchito kwambiri ndi ogwiritsa ntchito mphamvu.Chipangizocho ndi choyenera kupangira magetsi, mafuta, mankhwala, zitsulo, nsalu, nyumba zapamwamba ndi mafakitale ena ogawa mphamvu.M'mafakitale akuluakulu amagetsi, makina a petrochemical ndi malo ena okhala ndi makina apamwamba kwambiri ndipo amafuna mawonekedwe apakompyuta, monga magawo atatu a AC pafupipafupi a 50 (60) Hz, ovotera 380V (400), (600), A low- voteji wathunthu wa zida kugawa mphamvu kugawa mphamvu, galimoto pakati kulamulira ndi zotakasika mphamvu chipukuta misozi mu kupanga magetsi ndi kachitidwe magetsi ndi oveteredwa panopa pansipa 4000A.Chipangizochi chikugwirizana ndi IEC439-1 "Low-voltage Switchgear and control equipment", GB7251 "low-voltage switchgear", ZBK36001 "low-voltage withdraw-type switchgear" ndi miyezo ina.
Zamalonda
- Kupititsa patsogolo kutentha kwa adaputala, ndi kuchepetsa kwambiri kutentha kowonjezera chifukwa cha kukwera kwa kutentha kwa adaputala ku cholumikizira, mutu wa chingwe ndi kugawa;
- Kupatukana pakati pa mayunitsi ogwira ntchito ndi zigawo ndizomveka bwino komanso zodalirika, ndipo kulephera kwa gawo linalake sikumakhudza ntchito yamagulu ena, kotero kuti kulephera kumakhala kochepa;
- Kukonzekera kwa malo a basi kumapangitsa chipangizocho kukhala champhamvu komanso kukhazikika kwamafuta ndikwabwino, kumatha kupirira 80/176kA lalifupi mayendedwe apano;
- Chiwerengero cha mabwalo a MCC nduna ndi mkulu monga nthawi 22, mokwanira kuganizira zofuna za lalikulu limodzi mphamvu mphamvu m'badwo, dongosolo petrochemical ndi mafakitale ena yodzichitira khomo magetsi (makina) gulu;
- Kugwirizana pakati pa chipangizo ndi chingwe chakunja kumatsirizidwa mu chipinda cha chingwe, ndipo chingwecho chikhoza kukhala pamwamba ndi pansi.Zero sequence current transformer imayikidwa mu chipinda cha chingwe kuti athandizire kukhazikitsa ndi kukonza;
- Momwemonso mphamvu yogawa mphamvu imatha kufanana ndi riyakitala yochepetsera kuti ichepetse mayendedwe afupiafupi, kukhazikika kwamagetsi a basi pamtengo wina, ndikuchepetsa pang'ono zofunikira za mphamvu zazifupi za zigawo;
- Chigawo chojambulira chili ndi mapulagini achiwiri okwanira (ma 32 awiriawiri a 1 unit ndi pamwambapa, ma 20 pa 1/2 unit) kuti akwaniritse zofunikira za kuchuluka kwa malo olumikizirana ndi mawonekedwe apakompyuta ndi loop yowongolera.
Gwiritsani Ntchito Chilengedwe
- 1. Kutalika sikudutsa 2000m.
- 2. Kutentha kwa mpweya wozungulira sipamwamba kuposa +40 ° C, ndipo pafupifupi kutentha mkati mwa maola 24 sipamwamba kuposa +35 ° C, kuzungulira.
Kutentha kwa mpweya sikutsika kuposa -5 ℃. - 3.Atmospheric mikhalidwe: Mpweya ndi woyera, chinyezi chapafupi sichidutsa 50% pamene kutentha kuli + 40 ℃, ndipo kutentha kumakhala kwakukulu.
Kutentha kwakukulu kumaloledwa pa kutentha kochepa. - 4. Palibe moto, ngozi ya kuphulika, kuipitsidwa kwakukulu, kuwonongeka kwa mankhwala ndi kugwedezeka kwamphamvu kwa malo, kuipitsa, ndi zina zotero.
Kalasi yachitatu, mtunda wa creepage weniweni ≥2.5cm/KV, ndipo kupendekera kwa ndege yoyima sikudutsa 5°. - 5. Malo olamulira ndi oyenera kuyendetsa ndi kusunga kutentha kotsatira, -25 ℃ ~ + 55 ℃, mu nthawi yochepa.
Musapitirire +70 ℃.
