Sivacon 8PT Low Voltage Withdrawable MCC Switchgear
Mawu Oyamba
Magawo amtundu wa GPS1 ndi a Nokia ophwanya zida zamagetsi zotsika mphamvu, zomwe zili ndi ukadaulo wamagetsi ozungulira, ukadaulo wokhazikika, ukadaulo wamapangidwe ochotsa ndi ukadaulo wamapulagi.Ili ndi otetezeka, odalirika, osinthika, ogwiritsidwa ntchito kwambiri pamakampani omanga ndi ukadaulo wamakampani.
Chogulitsacho chili ndi izi:
● Zida zogwiritsira ntchito magetsi otsika kwambiri (TTA);
● Basi yopingasa yolumikizana yokonzedwa pamwamba pa switchgear;
● 3-Pole ndi 4-pole busbar system adavotera panopa mpaka 7400A;
● Chiyerekezo chapamwamba kupirira panopa 1pk akhoza kufika 375kA;
● Kuzama kwakukulu kwa chipinda cha chipangizo, choyenera kuyikapo mitundu yosiyanasiyana;
● Chipinda cha chipangizochi chikhoza kugawidwa m'magulu osiyanasiyana monga mawonekedwe a modulus;
● switchgear akhoza kuikidwa mbali imodzi, komanso akhoza kubwerera kumbuyo unsembe;
● Mzere wolowera ukhoza kukhala wochokera pamwamba kapena pansi;
● Zingwe zotuluka zimatha kulumikizidwa kutsogolo kapena kumbuyo kwa nduna.
Zida za GPS1 low-voltage switchgear zomwe zili ndi zida zinayi zonse: Chophwanyira chomangira, kamangidwe kokhazikika, kamangidwe ka pulagi ndi kapangidwe kake.
Mapangidwe ophwanya ntchito, mulingo wapano wa basi ukhoza kugawidwa mu 3200A, 4000A, 7400A, chipinda cholumikizira chingwe m'mbali kapena kumbuyo, wosweka dera amatha kusamutsidwa kuchokera pamalo olumikizirana, malo oyeserera kupita kumalo akutali.Wosweka yekha pamalo akutali, chitseko chikhoza kutseguka, izi zimatsimikizira chitetezo chamunthu payekha.
Mapangidwe okhazikika a kabati yokhazikika, omwe amapanga mabwalo odyetsa mu kabati akhoza kukhala kuphatikiza kulikonse.nduna yaika zokhazikika kapena kuyika mtundu woumbidwa ma circuit breakers(MCCB), zolumikizira zamtundu wa fuse, kapena zolumikizira zamtundu wa mizere zokhala ndi fuse, mabasi ake ogawa mabasi opitilira apo ndi 1400A;Gulu lotchinjiriza la mabasi ogawa a kabati ya fuse ndi IP20B, pogwiritsa ntchito mizere ya 3NJ6 fuse switch, chipangizocho chitha kusinthidwa popanda mphamvu pansi pa nduna yonse.Power factor compensation cabinet ili ndi mtundu wotsamwitsa komanso wosatsamwitsidwa.
Kabati iliyonse yochotsamo imakhala ndi malo olumikizirana, malo oyesera komanso malo akutali.Zojambulira zopitilira 125A zili ndi makina omwe amatha kuthana ndi kabati ndikupititsa patsogolo kukangana.Dalalo yofikira pakali pano ndi 630A, chojambula cha modulus ndi 100,150,200,300,400,500,600,700mm.
Pulagi-mu mtundu lakonzedwa kuti chipangizo chokhazikika anaika pa slats, pulagi mu dera lalikulu ndi wothandizira dera pulagi ndi slat, waukulu dera chingwe kubwereketsa kutenga mawaya okhazikika olumikizidwa mwachindunji ku zipangizo kubwereketsa.Mapangidwe awa ndi okwera mtengo kwambiri.
Kuti agwirizane ndi zosowa zamainjiniya molingana ndi kapangidwe kake ka BS, mabasi onse opangidwa adachitidwa 3S ovoteledwa kwakanthawi kochepa kupirira mayeso apano.
Mapangidwe a Frame ndi Enclosure
Magawo onyamula katundu a skeleton switch cabinet, omwe amapangidwa ndi mbiri yachitsulo yolumikizidwa wina ndi mzake, mawonekedwe a mafupa a GPS1 olondola komanso okhazikika.Pali mitundu iwiri yamapangidwe, yomwe ndi screw connection kapena welded.
● Mbiri ili ndi 25mm hole mtunda modulus kukwaniritsa zosowa zosiyanasiyana zowonjezera
● Kasupe wozungulira kasupe kungathandize kuti mwangozi asatuluke pachitseko mwangozi kapena mwangozi
● Denga lokhala ndi zipangizo zothandizira kupanikizika
Mpanda
Padenga mbale
Denga la denga limakulungidwa pa chimango, denga limatha kukwezedwa popanda kugwetsa switchgear, IPX1 kapena IPX2 denga lachitetezo chamtundu wamtundu wachitetezo lidzaperekedwa ngati zowonjezera.
Pansi mbale
Kuti musindikize SPS1 kuchokera pansi, mutha kuyika mbale zambiri zachitsulo, mutha kubowola mabowo pansi kuti muzitha kulumikiza zingwe.Kuti pakhale zofunikira zachitetezo chapamwamba, Mukayika mbale yapansi pamalopo mutha kugwiritsa ntchito kusindikiza kokhazikika kuti mutseke.
Mbali yakumbuyo ndi Side wall
GPS1switchgear kumbuyo ndi mbali zidapangidwa ndi mbale yachitsulo yosasunthika yosasunthika komanso zomangira zomangika pamapangidwe othandizira.
Partition mbale
Malinga ndi kulekana kwamkati kwamitundu yosiyanasiyana, pakuyika kabati ya GPS1 motsatana, mbale yogawa imatengedwa kuti ikhale yodzipatula pakati pa mawonekedwe a magawowo.Spacer imayikidwa kunja kwa chimango chakumanzere.
Tsatanetsatane wa Skeleton
Mawonekedwe Okhazikika amtundu ndi mawonekedwe
