When the regional power supply conditions are not met the requirements of reliability of power supply fire a load and secondary load, or get a second power supply is uneconomical from the substation area, should be set owned fire standby power (diesel generator).
Owned fire standby power are: emergency generator sets, batteries, uninterruptible power supply system (UPS), fuel cell.
High-rise building fire-owned power owned power generation equipment to the (self emergency generator set) requirements are:
Owned emergency generator set diesel generator sets and gas turbine generator sets two kinds.
When choosing diesel generator sets, should use high-speed diesel generator sets and brushless automatic excitation device. Because high-speed diesel generator sets with small size, light weight, reliable starting running. Brushless automatic excitation device has to adapt to a variety of start-up mode is easy to implement unit automation or remote control characteristics of the generator set, and when used with automatic voltage adjustment device supporting the use of static voltage regulation can guarantee less than 2.5% of disabilities.
Owned emergency generators should be installed quickly and automatically start and supply automatic switching devices, and has three consecutive self-starting function. For a class of high-rise buildings, from the start switching time of less than 30s; for other buildings, when using automatic starter difficulties may also be used to manually start device. Units should generally use electric starter, should not use compressed air starter. Generator set total number of units should not exceed 2 units, stand-alone capacity is generally in the 800kW and below.
Gas turbine generator unit includes a gas turbine, generator, control panels, starter batteries, fuel tanks, intake and exhaust, muffler and other equipment. Units can be divided into a fixed type, movable type and track type. Three-phase AC generator to the same period generators, brushless AC excitation mode.
Cooling the gas turbine without cooling and air self-cooled, combined combustion requires a lot of air, so the air turbine group needs than 2.5 to? 4 times Diesel. Therefore, the installation location must be convenient to consider intake and exhaust to the top or roof is appropriate, should not be located in the basement, due to lower intake and exhaust have some difficulty20kva diesel generator engine set for sale 30kva diesel generator engine set for sale 50kva diesel generator engine set for sale 60kva diesel generator engine set for sale 75kva diesel generator engine set for sale 80kva diesel generator engine set for sale 90kva diesel generator engine set for sale 100kva diesel generator engine set for sale 125kva diesel generator engine set for sale 150kva diesel generator engine set for sale 180kva diesel generator engine set for sale 200kva diesel generator engine set for sale 240kva diesel generator engine set for sale 250kva diesel generator engine set for sale 300kva diesel generator engine set for sale 400kva diesel generator engine set for sale 500kva diesel generator engine set for sale600kva diesel generator engine set for sale 800kva diesel generator engine set for sale 1000kva diesel generator engine set for sale 1250kva diesel generator engine set for sale 1500kva diesel generator engine set for sale 2000kva diesel generator engine set for sale
