A kind of space-borne miniaturized high-voltage transformer insulation tooling and insulation method

Abstract

The invention relates to an insulating tooling and an insulating method for an on-board miniaturized high-voltage transformer, belonging to the technical field of on-board power supplies. The present invention only encapsulates a high-voltage wire package and pins, which can greatly reduce the weight and volume of the transformer; Except for the solder joints, the transformer pins have almost zero potential to the peripheral, so no more insulation design is required. The transformer skeleton is simple and convenient for winding. The skeleton, potting and transformer winding materials are all made of high-reliability and long-life materials, which can be suitable for various harsh environments. The "ears" on both sides of the skeleton are used to fix the silver-plated wire, and the transformer is wound with enameled wire and then welded on the silver-plated wire. The top skeleton is a blind hole, and the middle is a through hole to control the position of the silver-plated line. After potting, the pins of the silver-plated wire are exposed and used as the primary and secondary pins of the transformer. The pins are located on both sides of the skeleton to achieve voltage isolation.

Description

technical field [0001] The invention relates to an insulating tooling and an insulating method for an on-board miniaturized high-voltage transformer, belonging to the technical field of on-board power supplies, and relates to the insulation and installation of small and medium-power transformers in high-voltage circuits in the power supply part of traveling wave tube amplifiers. The primary voltage of the high-voltage transformer is (to the ground) 10-12V, the secondary voltage (to the ground) is 6kV-10kV. Background technique [0002] The space-borne traveling wave tube power supply is a special high-voltage power supply with multiple outputs, and the maximum output voltage is up to 10KV. There are many kinds of high-voltage transformers in the power supply design. These transformers have a very high voltage difference between the windings at all levels, between the windings and the peripheral circuits, reaching 6000-10000V. The insulation and preparation of space-borne hi...

Problems solved by technology

There is usually a thick insulation skin outside the high-voltage line, which requires a larger winding window area, which increases the volume of the transformer
