Electrical system

Electrical system The electrical system is related to power supply, electrical equipment and communication facilities. In terms of spatial data, the ground power supply system diagram, underground power supply system diagram, power line laying diagram, signal line laying diagram, electrical equipment layout of substation and electrical equipment layout of working face are adopted. (1) ground power supply system diagram The ground power supply system diagram is a schematic diagram, which mainly demonstrates the layout of wires and lines on the ground of the mine. No attribute data. (2) underground power supply system diagram The underground power supply system diagram is a schematic diagram, which mainly demonstrates the underground wire layout of the mine. No attribute data. (3) power line laying diagram The power line laying diagram is divided into four layers: power line laying diagram, foundation roadway, map grid and map boundary. The layer of power line laying diagram mainly collects the wire line distribution of several points in the roadway. The attribute information mainly collects the name, voltage and length of each line. The other three layers are the same as the corresponding layers in the ventilation system diagram. (4) signal line laying diagram The signal line laying diagram is divided into four layers: signal line laying diagram, basic roadway, map grid and map boundary. The layer of signal line laying diagram mainly collects spatial data such as the distribution of signal lights and the laying of signal lines. (5) electrical equipment layout of Substation The electrical equipment layout of substation has only one layer: electrical equipment layout of substation. The layer of electrical equipment layout of substation shows the layout of electrical equipment of pump house substation in Zone V, the layout of electrical equipment of - 25 central substation, 3# bunker substation and the layout of electrical equipment of - 140 central substation. The main equipment includes: high voltage switch cabinet, high voltage leakage line selection protection, transformer, explosion-proof switch, leakage relay, comprehensive protection of signal lighting, silicon rectifier panel, water pump starting cabinet, water pump, feed switch, etc. The attribute information includes the model and purpose description of these devices. (6) electrical equipment layout of working face The electrical equipment layout of the working face is divided into four layers: electrical equipment layout of the working face, foundation roadway, map grid and map boundary. The electrical equipment layout layer of the working face mainly collects the spatial information such as the distribution of various fans, switches, belts and wind power locks. The attribute information mainly includes the model and power of these devices. The other three layers are the same as the corresponding layers in the ventilation system diagram.
