SU86672A1 - Device for measuring the intensity of the electric field - Google Patents

Description

The subject of the invention is a device for measuring the intensity of an electric field, based on the use of an electrostatic generator with a clamping plate and a screen.

Known devices of the known kind have a number of moving parts, which reduces the measurement accuracy.

In the proposed device, moving parts are articulated due to the fact that the coloring of the B1 islasia, when the field is sepet; the dielectric constant of which varies depending on the alternating voltage applied to it from the auxiliary current source;

On the line heh shows the conceptual scheme of the proposed device.

Metallic measuring plastics 1. is covered with a plastippa 2 segioelectric, nnosgtts in a plectrical field E, and i / o i; oTOporo should be measured. Measuring plate 1 is connected to successor 3, at the output of which an electrical measuring device 4 is installed.

From the low-frequency generator 5 to all-absorbing electrodes 6, which are laid out to station 2, the electrical voltage with a frequency f is less than the critical one (which is already affected by the inertia of the segretostric). The PROM DTOM reduction of the electrical resistance of the electrical system will change from 2 to 1 {2f). In the case of a noisypxnocTjr field, the segretoelectric will also run at a frequency of 2f, and the amplifier will receive a sigpal, which will be measured by the frequency of the measured and measured field, then transferred to the electrical test device.
