Description
Technical field
The invention belongs to pulse power technical fields, more particularly to a kind of core pulse power supply and operation method.
Background technology
High power pulsed source has important application and current demand, but the high power arteries and veins of routine techniques approach in equipment
Power supply is rushed in miniaturization, fast-response or continuously available etc. there are bottlenecks.
In decades, the ways such as capacitor energy, inductive energy storage device and inertia energy storage pulse power generation are successively used both at home and abroad
Diameter develops high power pulsed source, but the factors such as low, high-current switch restrict by the energy density of conventional energy resource, existing
Or the following visible conventional high power pulse power is not avoided that volume is big, weight is big, needs the shortcomings of high-power primary source,
It is difficult to meet the needs of equipment.
Such as use highest energy storage density (about 1.2MJ/m now3) capacitor group, single export hundred megajoules of magnitudes
Electric energy, only the volume of capacitor group just reach 85m3, in addition for the battery pack or diesel-driven generator of capacitor charging energy supply, Yi Jiqi
It is controlled and accessory, and the total volume of the pulse power system of capacitive energy storage is not less than 170m3, excessively huge and when charging
Between longer or continuous use number it is limited, it is difficult to suitable for requiring mobility high equipment.Using capacitor as energy storage side
The pulse function limited power of formula is in the lower energy storage density of capacitor, with the raising of output electrical energy demands, the capacitance needed
The total volume and quality of device are also increasing so that the application scenarios of the equipment of mating this kind of power supply are limited by very large.

The output voltage of homopolar generator is too low (100~200V), if adding inductance coil energy storage-electric discharge, although
Voltage can be improved, but can greatly reduce transformation efficiency.The DC pulse electric energy of Compensated Pulsed Alternator and equipment is defeated
Enter between demand and there are problems that phase matched, also needs the switching technique of large capacity to realize, device is fragile.Inertia stores up
Energy impulse power power-supply must be pre-actuated to put aside kinetic energy, ability energy impulse power generation, this Working mould after Speed of Reaction Wheels is enough
Formula needs the time grown very much before meaning use, is not suitable for the equipment to be sought quickness of response speed.High rotating speed flies simultaneously
Wheel has apparent gyroscopic effect, this requires height to bearing support, must use the on-mechanical bearing of magnetic suspension mode, it is also necessary to grind
Hair.

Operation method includes step：
The fission fragment generated by pulsed nuclear reaction heap (1) nuclear fission reaction based on film-type fuel has higher energy
Amount, is pierced by Membrane Fuel surface by some energy and enters in Working medium gas, collides ionization, makes with Working medium gas atom
Working medium gas becomes the nonequilibrium plasma of high temperature and pressure；
After Working medium gas is converted into high-temperature high-pressure state, under the driving of pressure itself, it is expanded into jet pipe (21), by jet pipe
(21) enter the power generation of Magnetohydrodynamic(MHD) generator cutting magnetic line after accelerating to high speed；
It converts the kinetic energy of Working medium gas and interior energy to electric energy output by PULSED MHD GENERATOR (3)；
After Working medium gas flows through Magnetohydrodynamic(MHD) generator, gas collection tank (41) is flowed directly into from the outlet of magnetohydrodynamic generator drive end unit；
The Working medium gas recycling of injection is injected into pulse core by the passive mode of working medium circulation and afterheat exhausting system
Reactor (1) is internal, while the heat for being not converted to electric energy being dispersed into a manner of passive in environment；Thus by system
State substantially return to the condition before impulsive burst, for it is next hair pulse outburst prepare.
9. a kind of operation method of core pulse power supply according to claim 7, which is characterized in that the working medium circulation and remaining
The operational process of hot driving system, including step：
The heat deposited in fuel element will be such that the cooling water in blind hole vaporizes, and then be injected into water tank (11) and again
It is condensed back to inflow blind hole, to transfer heat to the water in water tank (11)；
And the Working medium gas after spraying and generating electricity by Magnetohydrodynamic(MHD) generator is completed, it is collected by gas collection tank (41)；Working medium gas
Body flows through heat exchanger (43) heat dissipation from gas collection tank (41), transfers heat to the water extracted out from water tank (11), this
A little water have part that vaporization generation water vapour occurs, and water vapour rising is flowed in the cooling fin at top, and steam is further by cold
But water circulation pipe (45) transfers heat to radiator (44), will be in Decay heat removal to surrounding air eventually by radiator；
Flow through radiator (44) water be condensed after, water tank (11) is flowed back by cooling water circulation pipeline (45).
