The sampling rate of the electronic atmospheric electric field meter is 0.5us, which can capture the multi-peak changes of lightning, distinguish cloud-to-cloud lightning and cloud-to-ground lightning, and can better distinguish the direction of thunderstorm clouds after adding GPS clock networking. Leading position of similar products

In the standard measurement state (plain, flat bottom, no tip effect), the average field strength of the electrostatic field is about 150V/M when the weather is fine, and the electric field strength of the electrostatic field can increase to +/- when thunderstorm clouds appear 15KV/high. When a single thunderstorm cloud layer or combined with the front thunderstorm cloud, the electric field strength increases for about 15-20 minutes, we think that when the electric field strength exceeds 2KV/M, the thunderstorm cloud is forming or is approaching, through the change of the large electric field strength and through The back-end software platform algorithm can quickly and accurately predict the local lightning strike situation in advance.

Three: Product advantages Advantage 1: IEC 62793, IEC 81/466/CDV/13 Description: The product based on FSM (electric field) measurement technology is the only device that can monitor the four processes of thunderstorm cloud development, and is most suitable for short-term monitoring. Warning for approaching lightning. 1. Cumulus cloud stage: The electric field intensity value has a clear upward and increasing trend. 2. Growth stage: It marks the occurrence of the first cloud-to-cloud flash, and there is often not too long a time interval between the first cloud-to-ground flash. 3. Mature stage: Cloud-to-cloud and cloud-to-ground lightning activities are very intensive. 4. Dissipation stage: The frequency of lightning occurrences is decreasing, and the electric field strength value gradually becomes weak until it returns to the normal level.

Four: The role of lightning early warning system

It can send out a lightning warning signal about 5 to 30 minutes before the lightning strike.

Remind field workers to stop or suspend outdoor operations in time, enter a safe area for lightning protection, and prevent lightning damage.

For some operations that may cause major hazards, appropriate measures should be taken in time before lightning strikes to prevent major lightning strike accidents. For example: outdoor operations in flammable and explosive places must be stopped or suspended at this time.

The automatic opening and closing system is adopted to isolate the power supply line from lightning, automatically switch UPS or start the generator set to supply power, and provide protection for some important equipment or uninterruptible and valuable services.

Provide protection against environmental disasters, such as forest fires.

In the standard measurement state (plain, flat bottom, no tip effect), the average field strength of the electrostatic field is about 150V/M when the weather is fine, and the electric field strength of the electrostatic field can increase to +/- when thunderstorm clouds appear 15KV/

high. When a single thunderstorm cloud layer or combined with the thunderstorm cloud ahead, the electric field intensity increases for about 15-20 minutes, we think that when the electric field intensity exceeds 2KV/M, the thunderstorm cloud is forming or approaching.

The intensity of the electric field changes and through the algorithm of the back-end software platform, it can quickly and accurately predict the local lightning strike situation in advance.
