Description
Technical Field
The present utility model relates to an outdoor lightning attack counter (LSC).
Background
Lightning is a naturally occurring electrostatic discharge during which there are two charged areas, both in the atmosphere or one above ground, temporarily neutralizing themselves, resulting in a transient release of on average one gigajoule of energy. Such discharges can produce a wide range of electromagnetic radiation from the heat generated by the rapid movement of electrons, which can severely damage electrical equipment.
The lightning attack counter is a tool used in a Lightning Protection System (LPS) for collecting information about the discharges suffered by the equipment and its characteristics, with the aim of improving the safety of the Lightning Protection System (LPS) and knowing whether emergency repair is required.
With the increasing popularity of lightning protection technologies, the use of lightning recording technologies is becoming more and more widespread due to the need for lightning event assessment and post-hoc analysis. However, most lightning recording related technologies and products on the market today are mainly indoors. For outdoor use needs with severe environments, a box body with a waterproof function is often simply added to meet the needs of higher protection levels. This not only facilitates installation, use and maintenance, but also increases costs and installation space.
CN 206740849U discloses a lightning attack counter which uses a nixie tube to display the number of lightning attacks and a toggle switch to check and clear the data. The lightning attack counter comprises a signal input circuit, a main control circuit and a function display circuit. The signal input circuit obtains lightning energy through the coil, and the lightning energy is input to the main control circuit through the optocoupler isolation. The master control circuit is used for the cumulative counting and control functions of lightning to provide circuit status information to the display.

As shown in fig. 7, the upper shield 14 also includes spring contacts 28 arranged to contact the lower shield 26.
In operation, lightning current is detected by induction of the outer coil of the lightning sensor 19, then lightning current data is transmitted to the data processing element 15, and after data processing, lightning current event information may be recorded and stored in the memory internally or externally.
Meanwhile, the data can be transmitted to a preset system or device for use in real time through the communication line 2 b.
The outdoor lightning attack counter (LSC) of the present embodiment may display the monitoring data and events through the display panel 20.
The lightning attack counter housing is provided with electromagnetic shields 14, 26 to protect it from lightning electromagnetic pulses carried by the monitored object. The electromagnetic shields 14, 26 are formed of upper and lower metal shells, wherein the upper shield 14 is provided with spring contacts arranged to ensure effective contact and connection with the lower shield 26, and the upper shield is further provided with two slots. The lower shield 26 is composed of a pentahedron metal case having a burring characteristic, and slots corresponding to two slots reserved on the upper shield are reserved to form a closed circular hole and/or a rectangular hole, so as to facilitate wire passing of the lightning sensor 19 and an external wiring unit. The electromagnetic shielding cover can be made of galvanized steel plates or copper-clad steel plates as main materials and can be formed by stamping.
According to the lightning attack counter (LSC), the upper shield 14 of the electromagnetic shield is fixedly mounted on the housing upper part 1a of the plastic housing. The lower shield 26 of the electromagnetic shield is fixedly mounted on the lower housing part 1b of the plastic housing.
