Pc cabinet energy storage mechanism arc extinguishing chamber

How is arc extinguished?

the arc by lateral spring pressure. At low currents the arc is extinguished by deionising action due to the cooling effect of the walls. Arc extinction is achieved in the higher current range by the arc extinguishing gasses produced in the pres-sure chamber flowing out of the pressure chamber into the expansion chamber.

How does the arc chamber affect the dissipation of post-arc energy?

The gas flow field within the arc chamber directly affects the dissipation of post-arc energy, which in turn affects the probability of thermal breakdown. In summary, the arc chamber can be optimized to improve the gas flow field, thereby enhancing convective flow and promoting the dissipation of post-arc energy.

How can arc chambers be optimized?

In summary, the arc chamber can be optimized to improve the gas flow field, thereby enhancing convective flow and promoting the dissipation of post-arc energy. By enhancing the dissipation of post-arc energy, the probability of post-arc thermal breakdown is reduced, ultimately improving the breaking capacity of the GCBs.

What is the best shielding scheme for arc extinguishing chamber?

The relative displacement of the moving shield cover and arc contact is determined to be 35mm as the best shielding scheme. the maximum pressure in the arc extinguishing chamber is 2.33Mpa and the maximum temperature is 26126K during arc burning, which appear on the surface of static arc contact.

How to optimize arc chamber of generator circuit breaker?

The arc chamber of generator circuit breaker is optimized from the perspective of accelerating gas flow field. Considering the arc radius, convection flux density and conduction flux density, the energy dissipation characteristics of different arc chambers post-arc are analyzed.

How is arc extinction achieved?

Arc extinction is achieved in the higher current range by the arc extinguishing gasses produced in the pres-sure chamber flowing out of the pressure chamber into the expansion chamber. Due to this rational com-bination of several extinguishing principles the entire current range of the load-break switch is effectively covered in all cases.
