Abstract

The invention belongs to the technical field of nuclear power station industrial safety and relates to a nuclear power station transformer light gas alarm response method and device, equipment and a medium. The method comprises the following steps that: after a gas relay sends out a light gas alarm, whether an oil and gas monitoring device operates normally is determined; after it is determined that the oil and gas monitoring device operates normally, gas sampling is conducted on transformer oil output by a power transformer through the oil and gas monitoring device, and first gas concentrations corresponding to all gases are obtained; according to each first gas concentration and a preset concentration threshold corresponding to the first gas concentration, whether the power transformer meets a transformer data abnormal condition or not is determined; and after it is determined that the power transformer meets the transformer data abnormal condition, it is determined that an internal fault occurs in the power transformer, a light gas alarm response process is executed, and fault detection is conducted on the power transformer through the light gas alarm response process. According to the nuclear power station transformer light gas alarm response method and device, the equipment and the medium of the invention, the gas sampling efficiency and safety are improved, and meanwhile, and power transformer abnormity diagnosis efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant industrial safety, in particular to a light gas alarm response method, device, equipment and medium of a nuclear power plant transformer. Background technique [0002] The power transformer is an important electrical equipment in the nuclear power plant unit. When the power transformer fails, it responds to various faults inside the power transformer through the gas protection method. For example, a light gas alarm is issued when the power transformer has a slight fault; The heavy gas trip causes the unit of the power transformer to stop running. Therefore, in order to better protect the safety of the power transformer, it is particularly important to deal with the slight fault of the power transformer, that is, after the light gas alarm is issued. [0003] At present, after the power transformer sends out a light gas alarm, it is necessary to manually sample the gas at the gas collect...
