GENERATION DEVICE FOR VERY FAST TRANSIENT OVERVOLTAGE

摘要

A generation device for very fast transient overvoltage (VFTO) is disclosed, which comprises an impulse voltage generator (11), an overhead line (12), a high-voltage bushing (13), a housing (10), a first bus section (14), a first harmonic resistor (15) and a steepening clearance (16); wherein the impulse voltage generator (11) is connected with one end of the first bus section (14) sequentially through the overhead line (12) and the high-voltage bushing (13); the other end of the first bus section (14) is connected with the first end of the steepening clearance (16) through the first harmonic resistor (15); the second end of the steepening clearance (16) is an output end for outputting VFTO. The generation device for very fast transient overvoltage can achieve better steepening effect.
