Product Description

GKD mining general low-voltage fixed switchgear yog tsim rau underground coal mines uas tsis muaj kev phom sij ntawm cov pa roj thiab cov hmoov av tawg.Nyob rau hauv lub hwj chim faib system ntawm lub hauv paus tswj chav tsev, qhov chaw nres tsheb, lub ntsiab qhov cua qhov duct thiab lub ntsiab qhov cua qhov hluav taws xob duct fais fab faib chav tsev los yog lwm yam zoo xws li industrial factories, ports, metallurgy, tshuaj lom neeg kev lag luam, high-sawv tsev hauv qab daus, loj warehouses, roj. cov teb, subways, thiab cov chaw ntub dej hauv cov tsev hauv av Nws yog ib qho ua tiav ntawm kev hloov pauv rau kev pib, tswj thiab tiv thaiv lub zog, kev faib hluav taws xob, teeb pom kev zoo, kev tswj lub cev muaj zog thiab lwm yam khoom siv hluav taws xob hauv peb-theem peb-xaim nruab nrab ntawm qhov tsis muaj hluav taws xob. ntawm 380 lossis 660v, ntsuas zaus ntawm 50Hz.
Lub switchgear ua raws li lub teb chaws tus qauv GB / T12173-2008 "General Electrical Equipment for Mining", GB3836.1-2010 "Explosive Atmosphere Part 1: General Requirements for Equipment", GB3836.3-2010 "Explosive Atmosphere Part 3: nce Kev Nyab Xeeb Hom "e" Cov Khoom Siv Tiv Thaiv" tau raug tshuaj xyuas los ntawm lub xeev-tsim lub chaw soj ntsuam, dhau qhov kev tshuaj xyuas, thiab tau txais daim ntawv pov thawj mining.Nws yog qhov tsim nyog rau lwm yam kev lag luam hauv av zoo sib xws xws li cov mines tsis muaj roj, cov hmoov av tawg tawg thiab cov mines uas tsis yog thee.

Cov khoom nta thiab cov qauv tsim

1. Lub ntsiab ncej ntawm lub txee hloov yog ua los ntawm txias-kuav los tiag steel phaj (los yog stainless hlau phaj) tom qab khoov, thiab ces ib nrab welded thiab assembled.Sab laug thiab sab xis mounting beams yog sib sau ua ke thiab welded nrog lub ntsiab ncej thiab steel kem nrog lub inherent modulus (29mm) mounting qhov.Tag nrho cov qauv: Nws muaj cov yam ntxwv ntawm cov neeg kho tshuab siab zog, tsis muaj deformation, siab installation precision, thiab yooj yim batch installation.
2. Lub txee muaj ob lub qhov rooj rau pem hauv ntej thiab nraub qaum, nrog lub xauv ntawm lub qhov rooj.Lub qhov rooj pem hauv ntej yog nruab nrog lub vaj huam sib luag tiv thaiv, ntsuas ntsuas thiab ntsuas lub teeb hauv chav ntsuas.Lub ntsiab busbar nyob rau hauv lub txee hloov yog muab tso rau sab sauv ntawm lub txee thiab tsau nrog nplaim-retardant high-strength insulating busbar clips.Cov khoom siv hluav taws xob tau teeb tsa rau ntawm cov kab teeb tsa hauv lub txee thiab fastened nrog bolts.Nws tuaj yeem hloov kho dawb do nce thiab nqis, sab laug thiab sab xis, thiab kev teeb tsa yooj yim thiab yoog raws.
3. Lub qhov rooj hloov qhov rooj yog kaw nrog cov roj hmab daim txhuam cev kom ua tiav qhov kev sib khi ntawm lub qhov rooj thiab lub txee, thiab qib kev tiv thaiv yog IP54.
4. Lub txee hloov pauv tuaj yeem ua haujlwm los ntawm lub hauv ntej ntawm lub txee, thiab tuaj yeem ntsia tau thiab tshuaj xyuas ntawm lub hauv ntej thiab nram qab ntawm lub txee.
5. Lub switchgear tuaj yeem siv ib leeg lossis sib sau ua ke hauv ib qho array.(Nws tuaj yeem hloov pauv hloov pauv xws li GGD, GCS, RMNS, thiab lwm yam.)
6. Lub cable nkag ntaus ntawv ntawm lub switchgear tuaj yeem qhib arbitrarily raws li lub thickness ntawm lub cable, thiab muaj bolts rau yooj yim general grounding.
7. Nws tuaj yeem nruab nrog mine to tiv thaiv ntaus ntawv thiab xaiv cov khoom tiv thaiv to.

Lub luag haujlwm tiv thaiv:
1) Kev tiv thaiv luv luv;
2) Kev tiv thaiv overload;
3) Kev tiv thaiv lub ntiaj teb to;
4) Kev tiv thaiv overvoltage thiab undervoltage;
5) Undervoltage tripping muaj nuj nqi.
Txoj cai thiab qauv:
Lub plhaub ntawm lub tshuab hloov pauv yog ua los ntawm 2 hli tuab txias-kuav los tiag steel phaj, uas tuaj yeem tiv taus qhov cuam tshuam lub zog thiab lub zog ntsuas kev ntsuas los ntawm lub teb chaws tus qauv thiab cov txheej txheem ntawm cov khoom no.Xim yog RAL7035.Cov kab hluav taws xob tau pub los ntawm cov kab trench, kaw nrog cov kua nplaum tawg tom qab kev teeb tsa, thiab lub txee hloov pauv tau kho.Cov inlets uas tsis siv thaum lub sij hawm installation yog thaiv nrog tawg-pov thawj kua nplaum.
