Problems solved by technology

[0003] Existing protective equipment can be divided into power supply, data and antenna feeder according to their functions, and the power supply can be further divided into DC and AC. However, these protective equipment often have certain limitations and can only protect specific energy or spectrum. (Waveform) electromagnetic pulse protection, especially for fast pulses with a short rising edge time, cannot achieve a comprehensive protection effect, and the protection efficiency needs to be further improved; if the requirements for comprehensive protection of the system and equipment are to be met, it must be in each system 1. A single-function electromagnetic pulse protection module, lightning protection module and EMI filter module are installed in the equipment. If these equipment are installed at the same time, the weight and size will be greatly affected, which is not conducive to the performance of the system and equipment.
In modern electronic technology, various systems and equipment require miniaturization, integration, and light weight, so the above-mentioned protection scheme is not practical; and the existing protection equipment does not have the function of detection and display, and cannot process the number of electromagnetic pulses. For statistics, it is not possible to detect the state of the pulse processing module

Description

technical field [0001] The invention belongs to the field of electromagnetic pulse protection, and relates to a strong electromagnetic pulse multi-stage protection device with a detection and display function. Background technique [0002] In modern society, various electromagnetic pulses generated by nature and man-made, such as lightning electromagnetic pulse, nuclear pulse (high-altitude nuclear electromagnetic pulse), high-power microwave, ultra-wideband, internal surge, clutter harmonic and strong Electromagnetic pulse interference, etc., the interference is more and more frequent, and damages sensitive electronic systems and equipment through the super-strong transient pulses generated; The larger the electronic device, the more sensitive it is and the more susceptible it is to electromagnetic pulse interference. Therefore, it is imperative to carry out comprehensive electromagnetic pulse protection for sensitive electronic systems and equipment. [0003] Existing pr...
