The invention is composed of shell, magnetic core, primary winding, secondary winding, insulating support, insulating medium and insulating paper. The shell is composed of edge pressure ring, main shell and end cover; the magnetic core is composed of outer magnetic core and inner magnetic core; the primary winding is composed of multiple external copper columns, left primary coil, middle primary coil and right primary coil; secondary The primary winding is composed of outer secondary coil, shielding ring, inner secondary winding and output terminal; the insulation support is composed of insulating cylinder, outer secondary coil support, combined insulating sleeve, inner secondary coil support, support plate, support rod, insulator constitute. The secondary winding adopts a double-layer structure, which increases the total number of turns of the secondary winding at the same length, realizes a high step-up ratio, and makes the transformer small and compact, ensuring the reliability of the device's high-power repetitive frequency operation and increasing the overall life.

Description

technical field [0001] The invention relates to a Tesla (Tesla) type pulse transformer, in particular to a compact double-layer secondary pulse transformer, which belongs to the field of high-power pulse drive sources. Background technique [0002] With the gradual deepening of the application of pulsed power systems in military, industrial, civil and other fields, especially the continuous progress of vehicle-mounted, airborne, and shipborne high-power microwave weapons, the requirements for the modularization and miniaturization of the system continue to increase. Modularity is convenient for modular transportation and maintenance, and the miniaturization of the system is suitable for the current loading capacity of motorized equipment. At present, there are two main boosting means of pulse power system, namely Marx generator and Tesla type pulse transformer. Tesla-type pulse transformers have the characteristics of no need for synchronous switches, compact structure, str...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to increase the inter-turn insulation of the secondary winding for the current Tesla-type pulse transformer with a high step-up ratio, which will cause the overall volume and weight of the transformer to double, which does not meet the requirements of the overall system. The problem of miniaturization and compactness requirements; and the insulation failure problem of breakdown between the primary winding and the secondary winding at the edge of the transformer in practical applications, which affects the stability of the continuous repeated frequency operation of the system, proposes a compact double-layer The secondary Tesla-type pulse transformer can not only realize the compactness and high step-up ratio of the Tesla transformer to the greatest extent, but also ensure the insulation reliability of the Tesla transformer when it operates repeatedly at high voltage.
