How to achieve correct lightning protection?

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.

Cobalt Based Alloy Powder

Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

The use of cobalt-based alloy powders in PTAW offers several advantages, including:

1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.

2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.

3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.

4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.

5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.

To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.

It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
