Testing method and testing device and testing system for high-voltage discharge component

The invention discloses a testing method, a testing device and a testing system for a high-voltage discharge component. The testing device comprises a power supply unit, a central processing unit and a first display unit, wherein the power supply unit is connected with the high-voltage discharge component and used for supplying electric power to the testing device and the high-voltage discharge component, the central processing unit is connected with the power supply unit and used for judging whether the high-voltage discharge component is powered on, and the first display unit is connected with the central processing unit and used for starting timekeeping when the central processing unit confirms that the high-voltage discharge component is powered on and displaying time values of the timekeeping. Through the testing method, the testing device and the testing system for the high-voltage discharge component, the problem that when an existing testing device in the prior art is used for testing the high-voltage discharge component, the specific testing time cannot be obtained is solved, and therefore the effect that the specific testing time of the high-voltage discharge component can be obtained when the high-voltage discharge component is tested is achieved.
