Abstract
The invention discloses a high-energy antiknock damping inductor, and belongs to the fields of high-energy physics and power electronics, and in particular relates to a protection device in a discharge circuit of a high-voltage direct-current capacitor, which is mainly used in a storage and discharge device of a high-voltage direct-current capacitor bank at present. By adopting a new special copper-nickel alloy conductor material, a hollow structure and a spiral winding process, the high-energy antiknock damping inductor solves the problems that the inductor is easy to damage and even seriously burst due to the electric force impact of instantaneous high current and heat expansion during high-energy injection under the conditions of high current (104A-105A) and high energy (106J).
Description
Technical field
The present invention relates to high-energy physics and field of power electronics, particularly the protective device in the high voltage direct current condenser discharge loop.
Problems such as the present invention is mainly used in the HVDC capacitor group energy storage electric discharge device, and like product explosive rhegma when receiving large-current electric power and shock heating expansion and impact is bad in the solving device.
Background technology
All the time,, generally only require its nominal inductance amount that reaches, and require to reduce its DC internal resistance under the service condition satisfying as far as possible, reduce the loss of inductor, improve its efficient for conventional inductor.In recent years, along with the expansion of scientific research field, particularly, press for high-power antiknock inductor to pulse capacitor group formula electric discharge device and the continual renovation of laser equipment and the continuous application of new technology.This antiknock inductor not only requires to guarantee inductance value (unit: μ H), and will guarantee that (unit: m Ω), and it is 10 through the electric current on the inductor to its dc resistance that constitutes the inductor conductor
4A to 10
5A requires its absorbent energy to reach 10
6The order of magnitude.Under big electric current, high-octane situation, inductor not only will bear the vibratory impulse power of big electric current, but also will bear the thermal expansion under the high-energy situation, and these two kinds of mal-conditions all can make inductance damage, even is hit and explodes.
Summary of the invention
The technical scheme that the present invention is taked for its purpose of realization is: on the structural design of inductor, take the frame mode of air core inductor device, to adapt to the working range of its big electric current, solved the saturation problem of common ferrimagnetic material inductor; Selecting for use on the conductor material, adopting special corronil, should guarantee under the prerequisite of required inductance value; Its dc resistance is regulation parameter value (m Ω), but also needs the metal material of certain mass, could guarantee that capacitor is in discharge process; Inductor can absorb the energy (MJ) that its discharge is produced; And temperature rise must be unlikely to be produced high temperature rise by huge energy in the scope that metal material allowed, and destroys the structure of inductor.
This product is successfully applied in certain model device of the Chinese Academy of Sciences at present, and has obtained approval, has guided the expansion in other application.
The fundamental diagram of this inductor is as shown in Figure 1.
Description of drawings
Fig. 1 is the fundamental diagram of inductor of the present invention.
Fig. 2 is a front view of the present invention.Wherein 1 is the lead-out wire fishplate bar, and 2 are the coiling alloy material, and 3 is the poured with epoxy resin mixture, and 4 is the high temperature fiber material.
Fig. 3 is a vertical view of the present invention.
Embodiment
According to accompanying drawing and practical implementation instance the present invention is described further below.
The foregoing circuit operation principle is: after 24 road electric capacity platforms being arranged and 24 inductors being gone here and there mutually, be connected in parallel again, form capacitor group device.Through the HV terminal capacitor group is charged, when being charged to required voltage, the charge circuit automatic disconnection; Then through discharge switch S
1Discharge, thereby on load RL, produce huge energy.For the single channel inductor, every inductor absorbed energy QL=1/2*C*U
2
If when wherein a capacitor breaks down short circuit, remaining 23 capacitor all discharges through the inductor on the fault branch so, fault branch inductance absorbed energy Qg=1/2*C*23*U
2This shows under the malfunction that absorbing energy also will be tens times of regular picture energy.
Under big electric current, high-octane situation, inductance not only will bear the vibratory impulse power of big electric current, but also will bear the thermal expansion under the high-energy situation, and these two kinds of mal-conditions all can make inductance damage, even is hit and explodes.
Design example, each device parameter values in the typical circuit: inductor L
1-L
24Be 18 μ H, its impedance is 50m Ω, capacitor C
1-C
24Be 150 μ F, 25kV, the about 15m Ω of capacitor equivalent resistance value, the about 5m Ω of load RL.Inductor energy under the normal operation is 46.875kJ, and under the failure condition, it is 1078kJ that the fault branch inductor bears energy Qg.
