Ob Yuchai 16VC 2400kW siab-voltage containerized diesel generator sets delivered and commissioned by Zhaoyuan Hexi Gold Mine Co., Ltd. hauv 2021 - txhua qhov ntsuas 2400kW, ncaj qha txuas mus rau 10kV mine mine distribution network, ua haujlwm raws li N+1 hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hauv qab 2021 - txhua qhov ntsuas 2400kW. loads (qhov cua, dewatering thiab hoisting). Lub mine yog ib lub koom haum ua haujlwm ntawm Baoding Technology (002552) hauv Zhaoyuan, Shandong - Tuam Tshoj "Gold Capital".
1. Tom qab: Zhaoyuan thiab Hexi Kub Mine
Zhaoyuan, ib lub nroog- theem nroog hauv Yantai, xeev Shandong, tau raug xaiv "Tuam Tshoj Lub Peev Kub" (中国金都) los ntawm Tuam Tshoj Gold Association. Shandong yog lub teb chaws kub tshaj - ua lub xeev; Yantai coj lub teb chaws, thiab Laizhou thiab Zhaoyuan ua ke suav txog li 90% ntawm Yantai cov zis. Nyob rau hauv 2024 Zhaoyuan tau tsim 14.86 tonnes ntawm pob zeb hauv av.
Zhaoyuan Hexi Kub Mine Co., Ltd. ("Hexi Kub Mine") ua haujlwm hauv av kub hauv Hexi Village, Canzhuang Town, Zhaoyuan. Nrog thaj tsam mining txog 1.908 km² thiab muaj peev xwm muaj peev xwm ntawm 300,000 t / xyoo, tam sim no nws yog tag nrho -tus tswv lag luam ntawm Baoding Technology (002552). Hauv 2025 lub mine tau tsim 540.48 kg ntawm kub, nrog cov nyiaj tau los ntawm RMB 517 lab thiab cov nyiaj tau los ntawm RMB 183 lab - qhia meej txog qhov tseem ceeb npaum li cas, tsis muaj kev cuam tshuam lub zog rau kev ua haujlwm hauv av tau txais txiaj ntsig.
Kub mining yog ob qho tib si lub zog- hnyav thiab kev nyab xeeb- tseem ceeb: txhua tonne ntawm cov ore coj los rau saum npoo yog nyob ntawm hluav taws xob txuas mus rau hauv av.
2. Vim li cas ob lub 2400kW High-Voltage Container Sets
Cov mining hauv av muaj peb txoj hauv kev uas yuav tsum tsis txhob poob lub zog:
· Qhov cua (通风) - muab huab cua ntshiab thiab dilutes cov pa phem;
· Dewatering (排水) - ua haujlwm kom qhuav thiab tiv thaiv dej nyab;
· Hoisting (提升) - lub elevator ncej uas txav cov neeg ua haujlwm thiab cov khoom siv.
Cov no yog thawj -chav kawm "kev nyab xeeb loads". Ib txhij poob ntawm ob lub zog sab nraud pub rau cov neeg ua haujlwm, tso cai rau dej nyab, lossis cia cov pa roj. Cov cai tswj kev nyab xeeb ntawm kuv yog li ntawd yuav tsum muaj kev ruaj ntseg thaum muaj xwm ceev (thib peb) lub zog hluav taws xob.
Hexi Gold Mine commissioned ob Yuchai 16VC 2400kW siab -voltage thawv teeb nyob rau hauv 2021 kom tau raws li qhov xav tau no. Ob chav xa N+1 rov ua dua: ib lub teeb tuaj yeem muab kev pabcuam thaum lwm qhov tseem suav nrog qhov tseem ceeb, thiab qhov sib xyaw ua ke 4800kW yooj yim npog txhua qhov kev nyab xeeb. Lub 10kV ncaj qha kev twb kev txuas mus rau mine high -voltage switchgear tshem tawm qhov xav tau rau ib kauj ruam - nce transformer - tsawg poob, teb sai dua.

4. Tus nqi ua haujlwm txij li kev ua haujlwm
Txij li xyoo 2021 ob lub tsev tseem nyob hauv qhov kub- tos txais: ntawm qhov poob ntawm lub zog sab nraud lawv pib- pib thiab rov qab hluav taws xob rau qhov cua, dewatering thiab hoisting, ua kom muaj kev nyab xeeb khiav tawm thiab tswj dej nyab tsis tu ncua.
N+1 layout txhais tau hais tias kev saib xyuas niaj hnub yeej tsis tawm hauv qhov kuv tsis muaj kev tiv thaiv - ib txheej ib txwm muaj. Cov khoom seem yog tus qauv thiab kev saib xyuas ncaj qha, haum rau kuv qhov siab - qhov yuav tsum tau muaj. Rau cov mines hauv av zoo sib xws, "daim phiaj tseem ceeb + redundant siab-voltage container standby" architecture tau dhau los ua tus qauv kev tiv thaiv.
5. Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog Hexi Gold Mine 2400kW siab -voltage thawv generator teeb?
A: Ob lub Yuchai 16VC 2400kW siab -voltage containerized diesel generator teeb tsa los ntawm Zhaoyuan Hexi Gold Mine hauv 2021 rau kev tos txais xwm txheej ceev ntawm lub neej hauv av- kev nyab xeeb loads (qhov cua, dewatering, hoisting).
Q: Vim li cas lub mine kub xav tau standby generator teeb?
