The hottest summer months of the year have come and summer thunderstorms are common, so the data center must make lightning protection measures. The destruction of lightning is mainly due to the violent discharge that occurs when the potential difference between the clouds or between the clouds and the earth and between the cloud and the air reaches a certain level (25-30 KV/cm).
How to avoid outdoor lightning strikes?
1. In the event of a sudden thunderstorm, you can kneel down and lower your height, while keeping your feet together to reduce the harm caused by the step voltage.
2, do not shelter under the big tree.
3. Do not stay on the side of the water body (river, river, lake, sea, pond, canal, etc.), depression, mountain top, or roof.
4, do not hold metal objects and then call the phone.
5, do not touch or near the lightning protection ground wire, water pipe, electrical grounding line.
Power surge protector features:
1, selection of high-quality varistors, reliable quality, stable performance
2, modular design, can be hot plug, easy to test or replace
3, with remote alarm device for easy remote monitoring
4, using temperature control circuit breaker technology, over-current, over-voltage dual automatic protection circuit
5, there is work, fault display, deterioration status at a glance
6, fast response time
7, large flow capacity, low residual pressure
8, easy installation, easy maintenance
Lightning damage to the safety monitoring system is manifold. Lightning protection is a complex issue. The lightning protection design of the safety monitoring system not only depends on the performance of the lightning protection device, but more importantly, the geography of the monitoring system must be taken into account before the design and construction of the monitoring system. Environment, design suitable cable deployment methods, shielding and grounding methods. In short, lightning protection design should be considered comprehensively to achieve good results.
