specific Embodiment approach 1

[0016] Specific implementation mode 1: the following combination Figure 1 to Figure 4 Explaining this embodiment, the capacitive load blasting magnetization compression generator with stator coil segmented operation described in this embodiment includes a stator coil 1, an armature 2 and a capacitive load 3.

[0017] The armature 2 is a cylindrical body, the stator coil 1 is divided into n-segment coils, the n-segment coils of the stator coil 1 are all spiral-shaped, and the armature 2 is arranged in the internal cavity formed by the n-segment coils, And each coil is coaxial with the armature 2. From the beginning of the armature 2, the end of each adjacent previous coil and the beginning of the subsequent coil are located on the same cross section of the armature 2, and the end of each coil Both are connected to one end of the capacitive load 3, and the end of the armature 2 is connected to the other end of the capacitive load 3.

[0018] The starting end of the armature 2 is th...

specific Embodiment approach 2

[0024] Specific implementation manner 2: the following combination figure 1 This embodiment is described. This embodiment is a further explanation of the first embodiment. Each stator coil 1 has a constant pitch, and the pitch of adjacent stator coils 1 increases geometrically from the beginning of the armature 2. Other components and connection relationships are the same as in the first embodiment.

[0025] The loss caused by the Joule heat of the resistance is very serious, especially at the end of the operation of the capacitive load blasting compression generator, because the current and current density are very large at this time. The winding method of the stator coil 1 with variable pitch can partially solve this problem. It can avoid a large number of Joules caused by unlimited increase in current density by increasing the cross-sectional area of ​​the corresponding section of the stator coil 1 at the end of the generator to maintain the current density at a constant accep...

Description

Technical field [0001] The invention relates to a capacitive load blast magnetization compression generator with stator coils working in sections, belonging to the field of high-power pulse power supplies and magnetic compression. Background technique [0002] The magnetic blast compression generator is a pulse-type, inductive energy supply system developed in the late 1950s. It has a series of advantages such as small size, high energy storage density, deformable design, and low manufacturing cost. As a pulsed power source, the blast magnet compression generator is only an energy amplification device, and it also needs energy supply. Generally speaking, it has two energy systems. The initial energy provides the initial magnetic flux as a seed source to form the magnetic flux distribution to be compressed; while the high-energy explosive provides power consumption for it. The chemical energy released by the explosive drives the metal sleeve to expand and overcome the force of th...
