[Problem] To provide a high heat dissipation sheet that enables electrical insulation properties while also making possible a simple construction method. [Solution] In the present invention, short fibers with electrical insulation properties and high heat dissipation properties are electrostatically flocked at high density onto a base material coated with adhesive, under conditions that allow for high density electrostatic flocking, the erect short fibers are adhered and affixed, binder resin is impregnated and is hardened, and subsequently one surface of the sheet is polished so that the insulating and highly-thermally-conductive fibers penetrate and are arrayed at high density in the direction of the sheet thickness. As a result, a heat dissipation sheet is formed in which the fibers protrude from one surface while the opposite surface is made smooth so that heat from a heat generating body can be quickly absorbed by the opposite surface and quickly dissipated into the air by the fiber protrusion surface.

The embodiment of the invention discloses an ADN based single-component thruster adopting low-temperature plasma concerted catalysis. The ADN based single-component thruster comprises a spouting section, an ionization section, a catalysis section and a combustion chamber which are coaxially connected sequentially, wherein the two ends of the spouting section and the two ends of the ionization section are pressed by a front flange plate and a middle flange plate; an integrated structure formed by the catalysis section and the combustion chamber and the ionization section are pressed by the middle flange plate and a rear flange plate; the spouting section comprises the front flange plate, a front insulator and an anode chassis as well as gas and liquid supply tubes separately used for providing an ADN liquid propellant and gas; the ionization section comprises a cylindrical anode, a middle insulator, a barrel-shaped cathode, a rear insulator and the middle flange plate which are sequentially connected to the anode chassis; the middle flange plate and the front flange plate are matched and pressed through a locking bolt; the catalysis section comprises a rear flange plate and a catalysis bed; and the combustion chamber comprises an optical test window and a reserved sensor jointing base. The AND based single-component thruster has various ignition ways, and is of great significance in completely converting an existing catalysis dissociation ignition way.

The invention discloses a multilayer winding and a winding method thereof. In the process that the multilayer winding is embedded into an iron core, only the straight line edge is embedded into the iron core, the first arc edge and the second arc edge are not embedded into the iron core, in the scheme, a wire changes the position on the first arc edge, the first arc edge with wire turns not arranged neatly is not embedded into the iron core, and after winding of the multilayer winding is completed, it can be guaranteed that the structures and sizes of the two straight line structures of the winding are consistent, wire turn arrangement is neat, the size meets the tolerance requirement, the difficulty of the winding embedded into the iron core is lowered, damage caused by the iron core to insulating paintwork can be effectively avoided, and insulating reliability of use of the multilayer winding is guaranteed.

The invention discloses a super-high-voltage vacuum insulation device. A vacuum chamber is divided into a first vacuum chamber and a second vacuum chamber; one end of the first vacuum chamber is communicated with one end of the second vacuum chamber; the other end of the first vacuum chamber is provided with a grounding end interface; the other end of the second vacuum chamber is provided with a high-voltage end interface; a grounding wire is connected into the first vacuum chamber; a high-voltage wire is connected into the second vacuum chamber; the first vacuum chamber, the second vacuum chamber, the grounding end interface, the high-voltage end interface and the high-voltage wire are all made of an insulation material; and in the second vacuum chamber, the high-voltage wire is provided with an insulation coating corresponding to the inner wall of the second vacuum chamber. Thus, high voltage can be effectively prevented from generating electric arcs in the insulation device, and the insulation performance and service life of the insulation device can be effectively ensured.
