Electric triggering-electromagnetic driving hybrid multi-layer overvoltage protection gap assembly

The invention discloses an electric triggering-electromagnetic driving hybrid multi-layer overvoltage protection gap assembly, which solves the problem that the direct lightning energy absorption capability and the overvoltage protection level of a multi-layer gap overvoltage protection assembly are mutually restricted, and automatically controls the electric triggering action in a switch under the direct lightning overvoltage effect, so as to achieve the purpose of protecting the overvoltage of the multi-layer gap overvoltage protection assembly. The switch gap is controlled to be broken down and conducted, so that a controllable multi-gap part of the multi-gap assembly is short-circuited, the overvoltage multiple of a fixed multi-gap unit is increased, the response speed of the multi-layer overvoltage protection gap assembly to overvoltage is greatly improved, and the overvoltage protection level of the multi-layer overvoltage protection gap assembly is improved; and meanwhile, the electromagnetic driving m
