The invention relates to a frequency spectrum recording device, in particular to a ring electrode arrester lightning stroke frequency spectrum recording device. The ring electrode arrester lightning stroke frequency spectrum recording device comprises a ring electrode arrester. The ring electrode arrester is provided with a grounding wire. The ring electrode arrester lightning stroke frequency spectrum recording device further comprises a pulse magnetic field sensor and a lightning current peak value recording instrument. The pulse magnetic field sensor is provided with a coaxial cable coil and a cable connector, the coaxial cable coil is arranged outside the grounding wire in a sleeving mode, and the cable connector is connected with the lightning current peak value recording instrument. When the ring electrode arrester is subjected by the lightning stroke, the pulse magnetic field sensor inducts the lightning stroke flowing through the ring electrode arrester according to the Ferrari electromagnetic induction law, the lightning current peak value recording instrument can record the corresponding number of lightning stroke times and the lightning current, accordingly, a frequency spectrum curve of the ring electrode arrester is obtained, local power network reference parameters are provided for power designers of related areas, measures are adjusted to adapt to local conditions, and normal running of a power network is guaranteed.
Description
technical field [0001] The invention relates to a spectrum recording device, in particular to a lightning strike spectrum recording device for a ring electrode arrester. Background technique [0002] With the increase of the coverage of insulated wires in the distribution network, the problem of lightning disconnection is becoming more and more obvious. Therefore, it is becoming more and more important to prevent lightning breakage of overhead insulated conductors. [0003] The existing ring electrode arrester only has the function of lightning protection, and cannot record the number of lightning strikes and the intensity of lightning strikes. It is not convenient for power designers to collect relevant information, and it is impossible to obtain specific data of lightning strikes on the power network in relevant areas, and it is impossible to design the power network in combination with local conditions. It is not conducive to the safe operation of power lines. Contents...
