Abstract

The invention discloses a vacuum arc-extinguishing chamber, a vacuum direct-current high-voltage relay, and a preparation method of the vacuum direct-current high-voltage relay. The vacuum arc-extinguishing chamber comprises a ceramic inner cavity and a plastic outer shell which is used for surrounding the ceramic inner cavity and has high-temperature resistance and high-strength performance. Theceramic inner cavity and the plastic outer shell are sealed by ceramic glue. According to the vacuum arc-extinguishing chamber, ceramic is used as the inner layer of the arc-extinguishing chamber so as to meet the requirement for an arc-extinguishing function, and the shell of the arc-extinguishing chamber is fixed through high-strength plastic, so the plastic shell and accessories made of other metal materials can be conveniently sealed through ceramic glue to achieve the vacuum sealing effect.

Description

technical field [0001] The invention relates to the field of DC high voltage relays, in particular to a vacuum interrupter. In addition, the present invention also relates to a vacuum DC high voltage relay comprising the vacuum interrupter and a preparation method thereof. Background technique [0002] The existing vacuum interrupter is mainly made of glass or ceramics, and the glass is used as the airtight vacuum shell and the metal is added to the corresponding temperature through the solder (the selection range of the temperature is 600 ° C ~ 1700 ° C), so that it is welded into a sealed circuit. Vacuum interrupter. And it has been widely used in various fields. However, due to the low strength of the seal and the high brittleness of the glass itself, it will be broken as a whole when it is hit by a collision. At this stage, it is gradually replaced by a ceramic shell. [0003] Most of the ceramic vacuum interrupters are made of high-alumina ceramics and welded by meta...
