Problems solved by technology
Because the gas pressure in the interrupter chamber of the circuit breaker has local flow rate changes and local high pressure formation, the gas flow rate deduced by the SF6 gas pressure cannot truly reflect the real state of the gas, which has great limitations.

Description
technical field [0001] The invention belongs to the technical field of high-voltage testing, and in particular relates to a device and method for generating high-speed flowing SF6 gas. Background technique [0002] SF6 gas is a colorless, odorless, non-toxic, non-combustible inert gas with good electrical insulation properties and excellent arc extinguishing properties. Its electric strength is 2.5 times that of air, and its arc extinguishing ability is 100 times that of air. It is a new generation of ultra-high voltage insulating dielectric material. At present, SF6 gas has been widely used in high-voltage circuit breakers, SF6 gas-insulated switchgear, and SF6 gas-insulated transformers. [0003] The application of SF6 gas in the power industry has two states: the state of constant gas pressure and the state of high-speed flow of gas. In the state of constant gas pressure, the pressure range of SF6 gas is 0.1MPa~1MPa. In this pressure range, SF6 gas has good insulation p...
