Abstract

The invention discloses an emergency steam turbine generator unit for a nuclear power station, and relates to the technical field of steam turbines, the emergency steam turbine generator unit comprises a steam turbine, a lubricating oil system and a generator connected with the steam turbine through a coupler, the steam turbine comprises a main shaft, a cylinder and a gear reduction mechanism, a first-stage impeller and a second-stage impeller are arranged in the cylinder, and a front steam seal is arranged at one end of the cylinder; the lubricating oil system comprises a gear oil pump and an oil tank which are connected with each other, the gear reducing mechanism is connected with the hydraulic speed regulating mechanism and connected with the main shaft through a coupler, one end of the main shaft is provided with a front bearing seat, and the other end of the main shaft is provided with a rear bearing seat. The front bearing seat and the rear bearing seat are both connected with a pipeline of a lubricating oil system, and the main shaft penetrates through the front steam seal, the primary impeller, the secondary impeller and the rear steam seal. The problems that in the prior art, a nuclear power station emergency power supply system is insufficient in reliability, a turbine generator has overspeed risks, and lasting power supply is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to an emergency steam turbine generator set for a nuclear power plant. Background technique [0002] The power system in a nuclear power plant mainly includes unit power system, standing power system and emergency power system. The unit power system mainly comes from the main generator or off-site main power; the backup power system mainly comes from off-site backup power; the emergency power system mainly comes from on-site batteries, emergency diesel generators, mobile diesel generators or turbogenerator sets, etc. Nuclear safety has always been the top priority of nuclear power technology and industrial development. Among them, the emergency power system used to deal with the power outage of the nuclear power plant is the last guarantee for the safe operation of the nuclear power plant, and its safety and reliability have high requirements. . [0003] The existing emerge...
