Abstract

The invention provides an emergency power supply system. The system comprises a battery pack, a monitor, a first controller and a frequency converter, wherein when alternating current (AC) information acquired by the monitor indicates AC supply stops, the monitor triggers the first controller which controls the battery pack to output a direct current (DC); and the frequency converter inverts the DC into AC and sends the AC to a working pump in an oil pump unit. In the emergency power supply system, by acquiring the AC supply information, when the AC supply stops, the battery pack is started to output the DC which is inverted into the AC and then the AC is sent to the working pump in the oil pump unit, thus providing a safe emergency power guarantee for large diffusions of blast furnace tops, hot blast heaters and other important blast-furnace equipment, and solving the technical problem that human safety and production safety are harmed seriously because a blast furnace system is in a dangerous state even explodes, which is caused by the factor that required emergency powers cannot be provided for the blast furnace system in time when the AC supply stops in the prior art.

Description

technical field [0001] The present application relates to the field of electric power supply, in particular to an emergency power supply system. Background technique [0002] The relief valve on the top of the blast furnace needs to be opened quickly to release the gas quickly when the blast furnace system stops working due to a power outage. The opening of the gas makes the gas flow back to the high-pressure blower pipe, which puts the high-pressure blower and its pipe in a dangerous state, or even explodes, seriously affecting the safety of work and production. [0003] At the same time, the valves of the blast furnace hot blast stove need to be cut off or closed quickly when the blast furnace system stops working due to a power outage. The valves of the furnace cannot be cut off or closed in time, so that the gas flows back into the combustion fan and its pipeline, which puts the combustion fan and its pipeline in a dangerous state, or even explodes, seriously affecting ...
