Description

technical field [0001] The invention relates to a computer storage system, in particular to a storage system for partial discharge state data of a high-voltage switch cabinet. Background technique [0002] With the development of the national economy and the support of relevant industrial policies for the power industry, the power industry has become an important pillar to ensure the operation of the national economy. With the development of the power industry, the requirements for the stability and reliability of power system operation are getting higher and higher, and the disadvantages of ordinary power grids are gradually exposed. Therefore, in the case of traditional grid operation problems, smart grid is entering people's field of vision, and has gradually become the main force of modern urban grid transmission. The smart grid is derived from the fusion of modern advanced technologies, such as intelligent decision-making technology, integration technology, modern meas...

Problems solved by technology

At present, the high-voltage switchgear monitoring system mostly uses non-volatile FLASH as the storage medium. According to the first-in-first-out recording principle, the data waveform of the latest action is saved, and it is erased after the recorded event exceeds this range. Large-capacity data is not easy to store.
