Measuring probe for optical fiber power-frequency high-voltage electric field

The invention discloses a measuring probe for an optical fiber power-frequency high-voltage electric field. The measuring probe is characterized by comprising a measuring electrode, a signal processing module, an A/D (Analog to Digital) conversion and data preprocessing module, a transmitting module and an optical fiber, wherein the signal preprocessing module, the A/D conversion and data processing module, the transmitting module and the optical fiber are sequentially connected. The measuring probe disclosed by the invention has the beneficial effects that 1, a power-frequency electric field can be measured through a charge induction electric field measuring method, an electric field measuring value adopts a digitization mode, transmission is carried out by the optical fiber, and an electric field probe adopts a spherical closed structure, thus the anti-interference capacity is extremely strong; 2, the working is stable, the size can be very small, the influence on a surrounding electric field is small, the carrying and the installing are convenient, independent working can be realized, and the influence on the measuring probe by an external environment is small; 3, compared with the expensive price of an electric field measuring instrument at present, the manufacturing cost of the measuring probe is lower, and the measuring probe can be popularized and applied to an electric system on a large scale, can be used for electromagnetic environment detection and has a good application prospect and a wide using range.
