开滦钱家营矿是年产400万吨原煤的大型矿井。主井提升采用一台φ4.5m×4绳落地式多绳提升机,箕斗容量32.5t,直流电动机容量为2×2500kW。副井提升采用两台φ3m×4绳落地式多绳提升机,其中一台为双罐笼,另一台为罐笼平衡锤,两台提升机的直流电动机容量均为1150kW。主副井三台提升机全套设备是1978年从西德引进的,当时没引进动态补偿装置。1984年安装提升设备时,水电部颁发了谐波管理暂行规定标准,才意识到高次谐波问题的严重性。设计施工建设单位共同建议,经煤炭部和国家计委批准,从瑞士BBC公司引进一套补偿装置,以解
Kailuan Qianjiaying Mine is an annual output of 4 million tons of raw coal mines. The main shaft to enhance the use of a φ4.5m × 4 rope floor-type multi-rope hoist, skip capacity of 32.5t, DC motor capacity of 2 × 2500kW. Vice-shaft hoist using two φ3m × 4 rope floor-type multi-rope hoist, one for the two tanks, the other for the cage balancer, two hoist DC motor capacity is 1150kW. Master and auxiliary wells three hoist full set of equipment imported from West Germany in 1978, did not introduce dynamic compensation device. When installing lifting equipment in 1984, the Ministry of Electricity and MOH issued the Interim Provisions on Harmonization Management before realizing the seriousness of the problem of higher harmonics. Design, construction and construction units recommended jointly by the Ministry of Coal and the approval of the State Planning Commission, the introduction of a compensation device from the Swiss BBC company to solution
