Motion, space Ion Flow Field is formed, the Ion Flow Field and former electric field are superimposed to form new compound field so that measurement becomes more
Difficulty, measurement result find that, when space has a large amount of charged ions, the electric field as caused by charged ion can reach former electric field
3 ~ 5 times, such huge disturb brings huge challenge to the measurement of space electric field.
The main tool of electric field is " field mill " under measurement ion stream environment at present, and field is sharpened with special metal top plate structure
Space ion stream is stopped and imports the earth in real time, this special construction avoids the interference of ion stream, and makes the measurement of electric field
More precisely, therefore obtained being widely applied very much, but because field mill needs that charged ion is imported into the earth in real time, therefore limit
Making it can only measure on the ground, and the measurement of space electric field needs equipment to be measured under real space environment；In addition,
Because its volume is big, cost is high, field mill cannot be used for the minimizing of detection device, intelligent and rebuilding at low cost, these shortcomings
It all significantly limit field and grind the application in following high voltage electric field.
The content of the invention
It is an object of the invention to provide a kind of field to grind electric field instrument, can effectively stop that extraneous ion stream enters device,
And realize the accurate measurement of the compound field under ion stream environment.
To achieve the above object, the present invention provides following technical scheme：Electric field instrument is ground in a kind of field, including chassis, upper frame, the

Preferably, first top metal and the second top metal are symmetricly set on upper frame both sides.
Preferably, first upper metal and the second upper metal are located at same level height.
Preferably, the position of first bottom metal is higher than the second bottom metal.
Preferably, the chassis sets left and right two parts, and sets the isolation two-part division board in left and right.
Compared with prior art, beneficial effects of the present invention are as follows：
Measurement for DC electric field under ion stream environment, existing technology are mainly tested using rotating electric field instrument, still, rotation
The electric field of Near Ground can only be measured by turning electric field instrument, and rotating electric field instrument due to volume it is big, the shortcomings of power consumption is high so that it is not
Can be in the total electric field under the ion stream environment of aerological measurement space；And present invention employs special processing structure, avoid from
Influence of the subflow to sensor, total electric field and new electric field successfully divide by the floating ground structure of bilayer and analytic equation
From so as to obtain direct current total electric field.
