Abstract

The invention discloses an optoelectronic isolation shielding box with strong electromagnetic interference resisting performance, an optoelectronic isolation system with strong electromagnetic interference resisting performance and a method and belongs to the electromagnetic field. The system is characterized in that the system comprises a shielding box. The shielding box is characterized in that the shielding box includes a cuboid-shaped shell and a cover plate covering the shell; an aluminum material is integrally milled so as to form the shell; a plurality of small holes are formed in the shell; and optical fibers pass through the small hole. The shielding box, the optoelectronic isolation system and the method are applied to a synchronous triggering system, and therefore, the problem of influence on the operation of the synchronous triggering system caused by strong electromagnetic interference generated by high voltage higher than 4MV which is outputted by 24 Marx generators can be solved, nanosecond precision control of 24 paths of ultra-high power pulses in a complex electromagnetic environment can be achieved.

Description

technical field [0001] The invention relates to the electromagnetic field, in particular to a photoelectric isolation shielding box, a system and a method for resisting strong electromagnetic interference. Background technique [0002] In June 1967, a major accident caused by electromagnetic interference occurred at a US military base in Vietnam. According to reports, radio frequency energy emitted by a high-power radar on a U.S. warship at that time was coupled to a motor drive circuit of a missile rocket mounted on an aircraft, causing the motor to drive the missile rocket to ignite, and also triggered a fire on the flight deck of an aircraft carrier. other missiles on board. Caused a loss of US$20 billion in the United States. With the rapid development of various high-tech and cutting-edge technologies, various large-scale experimental systems are becoming more and more complex, and the electromagnetic interference between systems has attracted more and more attention ...
