Embodiment Construction

[0026] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] In the embodiment of the present invention, an ultra-high voltage vacuum insulation device is disclosed, which can insulate ultra-high voltages of 100,000 volts and above.

[0028] see figure 1 , the device of the present invention mainly includes a vacuum chamber. The entire vacuum chamber is made of insulating materials, such as polytetrafluoroethylene, ceramics, glass, rubber, etc. Although the entire vacuum chamber is made of insulating materials, the entire vacuum chamber is not limited to only one kind of insulating material, and different vacuum sections can be made of different insulating materials, which will be introduced in detail later.

[0029] In addition, the size...

Abstract

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.

Description

technical field [0001] The present application relates to the technical field of high voltage and insulation, in particular to an ultra-high voltage vacuum insulation device. Background technique [0002] The double-electrode structure in the device, because it is in the air medium, has poor pressure resistance and is easily broken down. The main reason is that a small number of free electrons in the air move at a high speed under the action of an electric field, collide with gas molecules to generate more electrons and ions, and the newly born electrons and ions collide with neutral atoms to further generate more electrons And ions, this avalanche ionization process will form a discharge channel between the electrodes, generate an arc, and eventually lead to electrode breakdown. [0003] However, since the chamber environment in the vacuum equipment is a vacuum environment, the probability of an avalanche electrical breakdown in the double-electrode structure in the vacuum...
