Abstract

The invention provides an electromagnetic pulse protecting device. The electromagnetic pulse protecting device comprises an electromagnetic pulse protecting module and an electromagnetic pulse detecting module which are integrally designed. The electromagnetic pulse protecting module comprises a voltage protecting unit and a current protecting unit, wherein the voltage protecting unit clamps voltage to be smaller than or equal to a preset voltage value when the voltage applied to the electromagnetic pulse protecting module exceeds the preset voltage value, and the current protecting unit cuts off a circuit of the current protecting unit to carry out over-current protection on a protected circuit when a current flowing through the electromagnetic pulse protecting module exceeds a preset current value. The electromagnetic pulse detecting module is used for detecting electromagnetic pulses acted on the electromagnetic pulse protecting module and generating a signal of a detected result. As the current protecting unit for limiting the passing rated current and a low-temperature welding spot with designed melting temperature are effectively combined, the electromagnetic pulse protecting module has the function of overheating and over-current open circuit protection for the internal integrated voltage protecting unit and can protect the internal voltage protecting unit in time, and the safety of rear-end electric equipment can be protected.

Description

technical field [0001] The invention relates to the field of electromagnetic pulse protection and surge suppression, in particular to an electromagnetic pulse protection device with overcurrent and overtemperature protection and current detection. Background technique [0002] With the rapid development of electronic technology, the functions and performance of electronic systems, weapon systems and other systems have also been greatly improved. At the same time, the impact of electromagnetic pulses in the above systems has also been strengthened. The impact of high-energy electromagnetic pulses shows greater vulnerability. For example, the modern army's high dependence on military electronic technology and equipment makes military electronic technology and equipment a key factor that directly affects the overall combat capabilities of weapon systems and even the entire military system. If the electronic technical equipment is damaged by the impact of high-energy electromagn...
