Abstract

The invention relates to the technical field of nuclear power, and provides a fire alarm system to solve the problem of low safety of a nuclear power plant. The fire alarm system comprises a centralized fire alarm controller; the first end of the centralized fire alarm controller is connected with the first branch of the first main power supply; a first standby battery is arranged in the centralized fire alarm controller; the first standby battery is connected with a first branch of the first main power supply; the second end of the centralized fire alarm controller is connected with the firstend of an external battery, and the second end of the external battery is connected with the second branch of the first main power supply. Thus, when the main power supply fails, the automatic fire alarm system can still give an alarm in time, so that the safety of the nuclear power plant is higher.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a power supply configuration structure. Background technique [0002] A nuclear power plant refers to the conversion of nuclear energy into thermal energy to generate steam for steam turbines, which then drive generators to form a power plant that generates commercial electricity. Nuclear power plants generate electricity by establishing systems and equipment that convert nuclear energy released by nuclear fission into electrical energy, with lower fuel costs and reduced pollution. However, once a safety accident such as a fire occurs in a nuclear power plant, nuclear leakage will cause serious consequences. [0003] The nuclear power plant is composed of nuclear island, conventional island and auxiliary buildings, and the automatic fire alarm system covers all areas of the nuclear power plant. In the existing fire alarm system, the main power supply is usually used to su...
