Abstract

The invention relates to the technical field of oscillographs, and discloses a centralized oscillograph based on an industrial personal computer, which comprises a wave recording device, the wave recording device comprises a base, a wave recorder, a first shell, a second shell and a sliding block, the top of the base is provided with the wave recorder and the first shell, the first shell contains the wave recorder, the first shell is internally provided with the second shell, the second shell contains the wave recorder, the bottom of the second shell is provided with the sliding block, and the sliding block is arranged in the sliding block. A sliding groove matched with the sliding block is formed in the top of the base, a limiting block is arranged at one end of the sliding groove, and the limiting block is in threaded connection with the sliding groove; according to the centralized oscillograph based on the industrial personal computer, the oscillograph with high protection performance is arranged, so that the situations that the working environment of the industrial personal computer is complex, the oscillograph is easily influenced by external factors and even impacted and damaged, the service life of equipment is shortened, and data recorded by the oscillograph is inaccurate are avoided.

Description

technical field [0001] The invention relates to the technical field of wave recorders, in particular to a centralized wave recorder based on an industrial computer. Background technique [0002] The fault recorder is used in the power system. When the system fails, it can automatically and accurately record the changes of various electrical quantities in the process before and after the fault. Through the analysis and comparison of these electrical quantities, it can analyze and handle accidents and judge It plays an important role in whether the protection operates correctly and improves the safe operation level of the power system. The fault recorder is an important automatic device to improve the safe operation of the power system. When the power system fails or oscillates, it can automatically record the changes of various electrical quantities during the entire fault process. [0003] When the existing wave recorder is used with the industrial computer, it is basically...
