The invention discloses a thunder and lightning waveform on-line monitoring device of an high-speed railway overhead line system. The thunder and lightning waveform on-line monitoring device of the high-speed railway overhead line system comprises a power supply module, a remote control switch, an i-Core 2 core board, a colleting circuit, a thunder and lightning flow sensor, a time service module, a GPRS network module, a machine case shell, a limiting cushion block and the like. The thunder and lightning waveform on-line monitoring device is erected on a backflow wire of a monitored overhead line, when the overhead line system is struck by thunder, the thunder and lightning flow sensor obtains sensing voltage, the collecting circuit collects thunder and lightning flow waveform signals, collected information is sent to an upper computer through a wireless network, a lithium battery is charged through an electricity taking coil coupling electricity taking method, and an external power source is not needed. The thunder and lightning waveform on-line monitoring device of the high-speed railway overhead line system provides an original basis for mastering thunder and lightning waveforms, resisting thunder scientifically, analyzing thunder strike accidents and positioning thunder strike faults, and is simple in structure, convenient to install and maintain and reliable in work.
