The application and structure type of ultra-high voltage equipment

our country's classification system specifies a pressure of more than 100MPa as ultra-high pressure, and modern high-voltage technology has obtained a high pressure of more than 361GPa, and the ultra-high speed impact test can also obtain higher pressure. At high pressure, the structure of an element or compound changes due to changes in atomic spacing and coordination. This change can be reversible. It can also be irreversible, and some phases formed at high pressure and high temperature can also be retained at atmospheric pressure, such as diamond and boron nitride. Therefore, with the advancement of high-voltage technology, it is possible to see more high-pressure phenomena and discover newer materials. The equipment designed using ultra-high voltage technology has an important application in the current industry. The success of modern artificial diamond is the result of the development of ultra-high pressure and high temperature technology, and the development of artificial diamond has further promoted the development of ultra-high pressure and high temperature technology.

Structure type of ultra-high pressure equipment:

In terms of structural form, ultra-high pressure equipment can usually be divided into: Piston-Cylinder (PC type), top hammer-directional type (Anvil-Cylinder AC type), Opposed-Anvil OA type, and Multiple-Anvil MA type

and multi-top hammer sliding type (Multiple-Anvil-Sliding System MASS type); MASS type can be divided into two categories: rotary type and non-rotating type.
