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

Abstract

The invention discloses a strong electromagnetic pulse comprehensive protection device with a detection and display function and belongs to the field of electromagnetic pulse protection. The device disclosed in the invention comprises a phase line L, a neutral line N, a ground line PE, a transient processing module, a steady-state filtering module and a detection and display module. The phase lineL is sequentially connected to the transient processing module and the steady-state filtering module. The neutral line N is sequentially connected to the transient processing module and the steady-state filtering module. The ground line PE is connected with the transient processing module, and the transient processing module is connected with the detection and display module. In the comprehensiveprotection device disclosed in the invention, fast pulses coupled to cables can be delayed through coordination between the transient processing module and the steady-state filtering module, thus rising edge time of the fast pulses can be reduced, and that sufficient time is left for a back stage system to process the pulses can be ensured; whether a pulse processing module is in a good working state can be detected, and statistics can be run on the number of electromagnetic pulses.
