This utility model relates to the field of arc extinguishing devices and discloses a high-voltage narrow-slit pressurized arc extinguishing device, including an arc extinguishing shell, a mounting frame, an arc extinguishing assembly, and two first gas generating components. The bottom of the arc extinguishing shell is provided with a gas generating port, and the two first gas generating components are symmetrically arranged on both sides of the gas generating port. When the circuit breaker is tripped, the moving contact swings, causing the electric arc on it to enter between the two first gas generating components through the gas generating port. The arc extinguishing assembly is disposed on the mounting frame and is used to extinguish the electric arc between the two first gas generating components. A narrow slit is formed between the two first gas generating components, which makes the arc heat more concentrated, increases the arc voltage, accelerates the pyrolysis rate of the gas generating material, and generates more arc extinguishing gas per unit time, thereby improving the arc extinguishing effect.
