Embodiment Construction

[0026] The embodiment of the present invention adopts the parameter of the torpedo propulsion motor as the armature resistance R a =0.011Ω, armature inductance L a =0.0001393H, excitation winding resistance R f =0.6129Ω, the mutual inductance L between the excitation winding and the armature winding af =0.00515H, supercapacitor C=20F.

[0027] The principle of the combined DC chopping speed regulation described in the present invention is to use the controllability of the turn-off device IGBT to quickly switch on and off the IGBT periodically, chop the DC voltage into a series of pulse voltages, and control the conduction ratio of the pulse. Realize the adjustment of the average value of its output voltage. Its combination part includes the combination of step-up chopper and current reversible chopper circuit, and the combination of the circuit can adjust the output voltage of the DC chopper in a wide range. In the normal working state of the torpedo, the output voltage U ...

Abstract

The invention relates to a combined direct current chopper adjuster for pushing fish torpedo, which comprises a dual-quadrant direct current copper (3), a direct current motor for pushing fish torpedo; a super capacity group (4) for supplying the electric energy of limited navigation speed of fish torpedo and filtering the wave of bus voltage; a ascending direct current copper (27) for lifting the supplying voltage of said dual-quadrant direct copper and the direct current motor; and a pre-charging device (28) for limiting discharge current of accumulator group, the ascending copper circuit can improve the output voltage of said fish torpedo direct current pushing system, increase the instant output powder of motor, and lift the instant limited speed of fish torpedo, while in limited speed, the copper can control the accumulator group in constant-current discharge mode to effectively confirm the discharge ability of accumulator group. The invention can adjust the speed of fish torpedo in large range with improved shot range.

Description

technical field [0001] It relates to a special combined DC chopper speed regulating device for torpedoes, which is equipped with a supercapacitor as an energy storage and an intermediate filtering device. Background technique [0002] Torpedoes are one of the offensive weapons of modern naval warfare. In order to meet the needs of war, torpedoes must develop in terms of high speed, long range, great destructive power, convenient and flexible use, good concealment, and good tracking. To obtain these advantages The performance must rely on a highly automated control system. [0003] Existing torpedo motion systems usually use constant-speed electrical transmission and small-range variable-speed transmission systems, such as those described in the following literature: Cai Niansheng, Modern Torpedo Power Battery Technology, Ship Science and Technology, pages 58-61, 2003, 2, its shortcomings After launching, the speed cannot be adjusted or the speed adjustment range and accurac...
