Diagnosis of Partial Discharge Based on the Air Components for the 10 kV Air-Insulated Switchgear. [PDF]

Sensors (Basel), 2022
Partial discharge (PD) is a common phenomenon of insulation aging in air-insulated switchgear and will change the gas composition in the equipment. However, it is still a challenge to diagnose and identify the defect types of PD.

Influence of buffer volume on the effect of pressure relief for the metal‐enclosed switchgear due to arc fault

IET Generation, Transmission & Distribution
The explosion accident due to the internal arc fault in the metal‐enclosed switchgear cannot be ignored. Therefore, improving the ability of switchgear to resist the arc fault has important significance.

Influence of the dissociation unit on pressure and temperature distribution in arc chamber of ACB during the breaking process

AIP Advances, 2021
To void breakdown between busbars, the dissociation unit is applied in the arc chamber of an air circuit breaker (ACB) to cool down the hot gas exhausted from the vent of the arc chamber in the interrupting process. Cooling efficiency and flow resistance
