我矿-66泵房共有DC100-80×4型排水泵6台,水泵匹配电动机功率160kW,排水方案为“两工一备三修”,紧急情况下3台可同时运行。井下没有高压电源,为避免因建设井下双回路变电所、更换地表高压发电机、申请增容等工程所带来的巨额投资,决定采用低压电缆由地表变电所引至井下泵房,实际输电距离0.6km。共分成3路,每路由2根动力电缆并联,如图1所示。 There are 6 DC100-80 × 4 type drainage pumps in our mine -66 pumping station. The pump matches the motor power of 160kW, and the drainage scheme is “two workmen and three workpieces”. In case of emergency, 3 sets can be operated at the same time. There is no high-voltage power underground, in order to avoid the construction of underground double-circuit substations, replacement of surface high-voltage generators, applications such as the huge increase of investment projects, the decision to use low-voltage cables from surface substations to the underground pumping station, the actual Transmission distance 0.6km. Divided into 3 routes, each route by 2 power cables in parallel, as shown in Figure 1.
