Abstract

The invention discloses a twisted wire core spiral linear inductor which includes a twisted wire core and an inner sleeve. The twisted wire core is wound in a spiral groove of the inner sleeve. The twisted wire core is formed by spirally twisting a plurality of metal wires and a plurality of aluminum wires. The inner sleeve is in a hollow cylinder shape, the outer wall of the inner sleeve is provided with the spiral groove, the bottom of the spiral groove is provided with a semicircular groove, the radius of the semicircular groove is the same as that of the twisted wire core, and each metal wire is a stainless steel wire or a manganese copper wire. The twisted wire core is formed by spirally twisting the plurality of metal wires and the plurality of aluminum wires. When a capacitor is subjected to internal breakdown, a large current passes through the inductor, the aluminum wires with a low melting point and low yield strength are melted, and stainless steel and the manganese copper wire are high in tensile strength and are still kept intact. The inductor impedance is significantly increased, which is equivalent to absorbing energy of the remaining capacitors to prevent the faultycapacitor from bursting.

Description

technical field [0001] The invention belongs to the field of electrical technology and pulse power technology, and more specifically relates to a twisted core spiral inductor. Background technique [0002] Pulse power technology refers to the electrophysical technology that stores high-density energy for a long time, performs rapid compression, conversion, or directly releases energy to the load in a short time. The initial energy storage system is an important part of the pulse power system. Common initial energy storage technologies for pulse power systems include capacitive energy storage, inductive energy storage, and mechanical energy storage. Among them, capacitive energy storage is easy to control, mature in technology, high in power density, and suitable for strong pulse discharge. Therefore, in high-voltage and high-current pulse power systems, parallel charging pulse capacitor banks with high energy storage density are often used as the initial energy storage syste...
