Problems solved by technology

Because the size of the switch circuit is large, the size of the insulator is large, and the manufacturing cost is increased.
However, in the electromagnetic pulse source that requires a fast output edge, it is very difficult to adjust the output pulse edge of the electromagnetic pulse analog source by separately designing the switch, inductance and load, and it is not desirable in terms of technology and manufacturing cost.

Embodiment Construction

[0038] The present invention is further described below in conjunction with accompanying drawing:

[0039] Such as figure 1 As shown, the compact inductive load integrated gas switch of the present invention adopts a two-electrode, self-breakdown structure. The anode electrode tip 3, the cathode electrode tip 2 and the outer insulating cylinder 1 form a main electrode cavity, which is sealed and filled with high-voltage insulating gas. The electrodes are machined from high conductivity, non-ferromagnetic brass material. The surface of the tip of the switch electrode transitions smoothly, forming a slightly uneven electric field with an electric field unevenness coefficient less than 2. The outer insulation cylinder of the switch is made of vacuum-impregnated glass fiber reinforced plastic cylinder with high mechanical strength and good insulation performance. The outer insulating cylinder is installed on the extension section of the load cone through the axial pressure tran...

Abstract

The invention provides a compact inductor and load integrated gas switch. The compact inductor and load integrated gas switch comprises an outer insulating cylinder, a conical cathode electrode tip and a conical anode electrode tip; the two ends of the outer insulating cylinder are sealed by the conical cathode electrode tip and the conical anode electrode tip respectively, the outer insulating cylinder is filled with high-pressure insulation gas, and at least one of the cathode electrode tip and the anode electrode tip is a hollow conical surface electrode structure. The hollow conical surface electrode structure comprises an electrode tip, an electrode base plate and an inductance unit arranged between the electrode tip and the electrode base plate, the electrode base plate is of a circular ring structure, the electrode tip, semi-circular-ring-shaped inductors and an inductor supporting section form a hollow conical surface layout. The inductors, load and switch integrated structure is obtained under the high-voltage and high-field conditions, so that a switch circuit structure is more compact, and self inductance is controllable.

Description

technical field [0001] The invention belongs to a compact inductance and load integrated gas switch, in particular to a compact high-pressure gas switch used for the leading edge adjustment technology of a large fast leading edge electromagnetic pulse source. Background technique [0002] The switch is a key device in the field of pulsed power technology, which connects the energy storage device and the load. The performance of the switch affects the rise time, shape and amplitude of the output voltage waveform. High-voltage switches used in the field of pulse power include gas switches, vacuum switches, semiconductor switches, mechanical switches, etc. Different applications have different requirements for switch performance and types. In large-scale fast-frontier electromagnetic pulse sources, controllable switching inductance, high withstand voltage, compact structure, simple and reliable control, etc. are often required. [0003] In the commonly used pulse power equipm...
