Beschreibung
Zusammenfassung:	A switch cabinet aging online monitoring method and system, wherein an insulating part in a switch cabinet is selected to perform simulated discharge, different simulated discharge voltages and simulated discharge times are used during the simulated discharge, different simulated discharge scenarios are preset, gas in each simulated discharge scenario is collected for detection and analysis, corresponding records of the simulated discharge scenario, a leakage current, a gas type, and a gas concentration are finally obtained, and then an aging monitoring gas and a corresponding gas concentration threshold are selected according to the corresponding records. A gas detector for a gas monitored for aging is mounted in the switch cabinet, said gas in the switch cabinet is monitored in real time by means of the gas detector to obtain gas monitoring concentration data, and if the gas monitoring concentration data is greater than a gas concentration threshold, an alarm is emitted. The aging of the insulating part is
