Faint, the difficulty of detection is big, and precision is low.And the present invention divides by detecting charged bubble movement locus detection electric field in the electric field
Cloth, reduces difficulty, improves accuracy of detection.
It addition, the present invention is except for electric field detector, it is also possible to for a kind of particularly bubble generating machine.Traditional bubble
The characteristics of motion of the uncontrollable bubble of machine, the movement locus of bubble cannot manual control, along with people to visual sense of beauty require increase
Adding, the bubble of traditional bubble generating machine blowout just cannot meet the demand of people.And the technology of the present invention, make bubble electrically charged, only
Need extra electric field before the lights, bubble can be made along regulation orbiting motion, produce more preferable visual sense of beauty.
Summary of the invention
In view of the shortcoming of appeal prior art, it is an object of the invention to provide a kind of electric field detector, be used for solving
The problems such as the detection of prior art intermediate ion stream is difficult, precision is low.Present invention is primarily targeted at: produce charged bubble, band
The bubble of electric charge is in the electric field by electric field force, and bubbles' trajectorise will change.Motion is taken with video camera in motor process
Video, through the image procossing of pattern process computer, draws charged bubbles' trajectorise, from which further follows that the distribution feelings of electric field
Condition, this technology is applicable to detect the distribution of extra high voltage direct current transmission line surrounding electric field.
The object of the invention to solve the technical problems realizes by the following technical solutions.Propose according to the present invention
