Abstract
The utility model relates to an optical fiber-aided ignition device. The device mainly comprises a detection module, a detection/trigger module, and a trigger module. By use of optical fiber as the transmission media, a control signal is transformed from an electric signal to an optical signal in the head end, and then is transmitted in the optical fiber; and the optical signal is transformed intoan electric signal in the tail end so as to achieve ignition function. The optical fiber-aided ignition device can be used not only for synchronous ignition of an impulse high-voltage generator but also for synchronous trigger ignition of a chopping device. Compared with the conventional ignition device, the optical fiber-aided ignition device used in the chopping device has greatly improved interference resistance so as to ensure more stable and reliable interruption time.
