High voltage pulse multi-strike anti-piracy device

Abstract

A high-voltage pulse multi-strike anti-piracy device, including a low-voltage direct current power supply, a low-voltage controllable switch, a high-voltage direct current charging unit, a high-voltage pulse multi-strike generator and a discharge electrode; the high-voltage direct current charging unit includes a rectifier, a charging unit capacitor C0 and a pulse The transformer and the rectifier include two parallel bridge arms; the high-voltage pulse multi-flash generator includes the generator current input terminal, high-voltage discharge terminal, charging resistor R1, trigger resistor R3, grounding resistor R2, high-voltage controllable switch, inductor generator L, generator charging capacitor C1 and generator triggering capacitor C2, and the high voltage discharge terminal is electrically connected to the discharge electrode. The high-voltage multi-pulse of the present invention has the characteristics of short duration (from tens of microseconds to hundreds of microseconds), high voltage amplitude (up to 200kV or even higher), high repetition frequency (above 100Hz), etc., although the instantaneous power It is very large, but the duration is short, and the power consumption is around several kVA.

Description

technical field [0001] The invention relates to the technical field of navigation safety equipment, in particular to a high-voltage pulse multi-flash anti-piracy device. Background technique [0002] Nowadays, piracy is rampant, which affects the safety of life, property, navigation and environment, and has a particularly bad impact on shipping. The ransom required by pirates to hijack an ocean-going cargo ship is about 4 million U.S. dollars, causing global annual losses of more than 20 billion U.S. dollars due to piracy attacks. [0003] In recent years, piracy activities have become increasingly rampant around the world, and vicious attacks on ships by pirates have occurred frequently. The attacks and interceptions of pirates in the coastal waters of the Gulf of Aden and the Gulf of Guinea have caused huge losses to shipping companies, maritime shipping and the world economy. Piracy has become the most troublesome problem faced by navies and shipowners of various countrie...

AI Technical Summary

Problems solved by technology

[0006] 2. The key issue of anti-piracy; the difficulty of anti-piracy mainly lies in the grasp of the strength of the strike. Fighting against piracy is not a traditional military operation. Weapons are not applicable, and civilian merchant ships are not allowed to carry lethal weapons, which is the root cause of incomplete anti-piracy technology

At present, there is still a lack of effective solutions in the world, and there is still a considerable gap between the existing anti-piracy equipment and the actual needs of anti-piracy, so it is imminent to develop new, practical and efficient anti-piracy weapons and equipment
