Underwater invisible blocking net device with distributed high-power power modules

Abstract

The invention relates to an underwater invisible blocking net device with distributed high-power power modules. The underwater invisible blocking net device comprises a direct-current power supply device, water surface pulse generators, conductor electrodes and underwater ballasts. The direct-current power supply device is used for converting alternating current generated by the mains supply or apower generator into stable direct current required by the water surface pulse generators. An output end of the direct-current power supply device is connected to an input end of each water surface pulse generator. The water surface pulse generators are used for converting the direct current generated by the direct-current power supply device into high-voltage pulses adjustable in positive and negative polarity to drive the conductor electrodes to form a pulse electronic blocking net. By a distributed high-power form of the water surface pulse generators, the invisible blocking net device is simple, efficient and capable of guaranteeing safety of retained creatures and supplying power uninterruptedly.

Description

technical field [0001] The invention relates to the technical field of power electronics engineering, in particular to an underwater invisible blocking device for a distributed high-power power supply module. Background technique [0002] In large water surface farms, water intakes of nuclear power plants and other occasions, in order to achieve effective interception of aquatic organisms or closed frogmen, the traditional method is to use nylon nets. However, the disassembly and assembly of nylon nets requires a lot of construction, and it is easy to attach aquatic organisms, which affects water passing and normal sailing. It needs to be cleaned and maintained frequently, and has a great impact on the surrounding water environment. [0003] In recent years, the inductive effect of organisms on electric fields has received extensive attention from academic circles at home and abroad. The inductive effect and yang effect of organisms under pulsed electric field conditions hav...

Problems solved by technology

This kind of power supply has the disadvantages of low power factor on the input side and large harmonic content; the output voltage cannot be automatically and continuously adjusted, and can only be adjusted manually in stages.

In particular, the power frequency transformer is bulky, which seriously affects the power density and portability of the pulse power supply device, causing inconvenience in the transportation and installation of the power supply
