Problems solved by technology

In the case of high current and high energy, the inductor not only has to withstand the vibration and impact force of high current, but also bears the thermal expansion under high energy. These two harsh conditions will damage the inductor, and even explode due to impact.

Embodiment Construction

[0010] The present invention will be further described below according to the accompanying drawings and specific implementation examples.

[0011] The working principle of the above circuit is: after 24 capacitor sets are connected in series with 24 inductors, they are connected in parallel to form a capacitor bank device. The capacitor bank is charged through the HV terminal, and when it reaches the required voltage, the charging circuit is automatically disconnected; then the discharge switch S 1 Discharge is carried out, thereby generating huge energy on the load RL. For a single inductor, the energy absorbed by each inductor QL=1 / 2*C*U 2 ;

[0012] If one of the capacitors is faulty and short-circuited, the remaining 23 capacitors are all discharged through the inductor on the faulty branch, and the energy absorbed by the inductance of the faulty branch is Qg=1 / 2*C*23*U 2 . It can be seen that the absorbed energy in the fault state will also be dozens of times of the n...

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 [0001] The invention relates to the fields of high-energy physics and power electronics, in particular to a protection device in a high-voltage DC capacitor discharge circuit. [0002] The invention is mainly applied in the energy storage and discharge device of the high-voltage DC capacitor bank, and solves the problems that similar products in the device are easy to burst and be damaged when subjected to the impact of high-current electromotive force and sudden thermal expansion. Background technique [0003] For a long time, for conventional inductors, it is generally only required to achieve its nominal inductance, and it is required to reduce its DC internal resistance as much as possible under the conditions of use, reduce the loss of the inductor, and improve its efficiency. In recent years, with the expansion of scientific research fields, especially for the continuous updating of pulse capacitor discharge devices and laser equipment and the continuou...
