Abstract

The invention relates to a system for measuring the DC combined electric field and the density of the ion flow. The invention is characterized in that the measuring system comprises a group of DC field intensity indicators connected with the signal collecting and processing device of the combined electric field by a signal cable, and a group of ion flow density board connected with the signal collecting and processing device of the ion flow by a signal cable. A / D converter modules are arranged in the signal collecting and processing devices of the combined electric field and the ion flow which are respectively connected with a control and signal display device in double ways by network tables. The control and signal display device is provided with dedicated software. The invention can conveniently set the channel collecting time of measuring signals, and can automatically measure the DC combined electric field and the density of the ion flow for a long time.

Description

technical field [0001] The invention relates to a measuring system, in particular to a multi-channel and integrated measuring system for direct current synthetic electric field and ion quantity density under a direct current line. Background technique [0002] Due to the randomness of the wire corona discharge of the DC line, the electromagnetic environment parameters closely related to the corona discharge, such as the distribution of the synthetic electric field and the ion density, are also random. When measuring the random quantity, it is necessary to obtain a large amount of data for statistical analysis. . For this reason, it is necessary to automatically collect all data and store them in real time when performing DC synthetic electric field and ion density experiments. At present, the DC synthetic electric field and ion density are usually measured separately in the test, and the data acquisition and processing system is simple, and the input parameters are cumberso...
