Description

technical field [0001] The invention belongs to the field of power systems, and relates to a high-reliability instantaneous and continuous triggering control device for forced triggering spark gaps in high-voltage / ultra-high-voltage power transmission systems. Background technique [0002] Forcibly triggered spark gaps used in high-voltage / ultra-high voltage transmission systems (devices) require forced-triggered related electronic circuit devices, which requires a forced-triggered trigger control device for spark gaps on ultra-high voltage platforms. The trigger control device system for forcing spark gap triggering on the high-voltage transmission system platform is different from the ground power supply and control device system, and it has the following characteristics: [0003] 1. The large current and high electromagnetic field on the EHV transmission system platform will cause great electromagnetic interference to the trigger control and power electronic circuits, whi...
