AI Technical Summary

Problems solved by technology

Existing electric field test instruments are generally used to test weak electric fields. When they are forced to be used in strong electric field tests, electromagnetic energy enters the interior of the test instrument through cables and metal holes, and induces currents that cause functional damage or work interference to the internal circuit. Therefore, it cannot Reflect the actual electric field characteristics
The response speed of existing instruments that can test strong electric fields is too slow, and it is difficult to test electric field signals with extremely short action times
Therefore, most of the existing electric field testing instruments cannot meet this demand.

Embodiment Construction

[0070] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0071] Such as figure 1 As shown, the transient electromagnetic pulse electric field tester consists of three parts: detector, receiver and optical fiber. The function of the detector is to extract the electric field signal, perform signal conditioning, and convert the electrical signal into an optical signal for output. Optical signals are transmitted over long distances through optical fibers. The function of the receiver is to receive the signal from the optical fiber, convert the optical signal into an electrical signal, and then perform signal conditioning on the electrical signal again to output and display. The length of the optical fiber is 50m, and the optical fiber is coated with double-layer UV-cured acrylic resin. Product performance. .

Abstract

The invention relates to a transient electromagnetic pulse electric field tester, which comprises a detector, an optical fiber and a receiver connected in sequence, wherein the detector is used for extracting an electric field signal, conditioning the signal, and converting the electric signal into an optical signal for outputting; the optical fiber is used for transmitting the optical signal remotely; the receiver is used for receiving the optical signal transmitted by the optical fiber, converting the optical signal into an electric signal, conditioning the electric signal once again, and outputting for displaying. The invention aims to provide an electric field testing device, which has the advantages of large dynamic range, short acting time and wide spectral range and meets the requirement of testing of special electromagnetic pulse signals.

Description

technical field [0001] The invention relates to an electric field testing device, in particular to an electric field device capable of testing a large dynamic range, a short action time and a wide spectrum range. Background technique [0002] With the development of electronic technology, semiconductors and integrated circuits are more and more commonly used in various equipment, so high-power electromagnetic pulses have a destructive effect on equipment and facilities that cannot be underestimated (such as lightning, power signals output by nuclear electromagnetic pulse simulators). It is increasingly important to assess the ability of equipment to resist electromagnetic pulse damage. The assessment process requires a special electric field testing device (the electric field testing instrument is required to test the electric field with a large dynamic range, a very short action time, and a wide spectrum range). Existing electric field test instruments are generally used t...
