And the safe operation of substations, implement the "prevention first, combining to fire," fire-fighting approach to prevent or reduce fire hazards, to protect personal and property safety, development of this specification. 1.0.2 This standard applies to the 3 ~ 600MW coal-fired units of the new, expanded plant and voltage 35 ~ 500kV, single transformer capacity 5000kVA and above the new ground substation. 1.0.3 fire power plants and substations should be designed with engineering situation, and actively use new technologies, new processes, new materials and new equipment, be safe to apply advanced technology and economic rationality. 1.0.4 Fire safety design of power plants and substations, in addition shall implement the provisions of this specification, there should be consistent with existing relevant national standards and specifications. 2 power plant construction (structures) of the fire hazard classification and fire rating 2.0.1 Construction (structures) of the fire hazard classification and fire resistance rating shall comply with the provisions of Table 2.0.1. Note: In addition to the provisions of this table construction (structures), the other building (structures) of the fire danger and fire resistance rating should be consistent with existing national standards, "architectural design code for fire protection," the relevant requirements. electrical control building (the main control building, network control building), microwave floor, relay room, when not taken to prevent the cable fire retardant measures after, the fire danger should be C. 2.0.2 Construction (structures) component of the combustion properties and fire resistance should be consistent with existing national standards, "architectural design code for fire protection," the relevant requirements. 2.0.3 does not burn body bearing members as the main plant and coal trestle, the non-load bearing wall for the body is not burning, its fire resistance of not less than 0.25h; difficulty burning body, its fire resistance is not should be less than 0.5h. 2.0.4 Turbine fuel tanks and oil pipelines near the head of steel structures fire protection measures should be taken. Fire resistance of non load-bearing components should be 0.5h, bearing members of the fire resistance should be 1h. When the generator for the island layout or operation of floor slab opening is large, the corresponding fire resistance of steel roof trusses should be 0.5h. 2.0.5 centralized control rooms, master control rooms, network control rooms, turbine control room, boiler control room and computer room interior decoration should be no burning of materials. 2.0.6 centralized control inside the building's centralized control room, computer room and other room walls should be no burning body, the fire resistance of not less than 1h. 2.0.7 main plant in the cable and the external walls of sandwich wall should be fire resistance of not less than 1h of the body does not burn. Cable exposed steel beams for the mezzanine of the roof, its fire resistance of not less than 1h. 2.0.8 main building above ground, fire district should not allow the construction area of more than 6 units of floor area; its underground should not be greater than 1 unit of floor area. 2.0.9 As part of the house underground coal unloading device, or coal tunnel and underground station connectivity, its fire district should not allow the floor area greater than 3000m2. 2.0.10 layers of other plants and fire district to allow construction area should be consistent with existing national standards, "architectural design code for fire protection," the relevant requirements. 2.0.11 steam room, between deoxygenation and boiler room, coal bunker coal bunker from time to time between the merger of the oxygen removal should be no wall between the burning body.
