When we buy a lightning protection device from a lightning protection manufacturer , how can we distinguish the quality of the lightning protection device?
1. From the response time: determine whether the lightning arrester can respond in time and the ability to quickly discharge the lightning current
2. It can be seen from the insertion loss: This refers to the installation of a lightning arrester. The impact of this lightning arrester on the line is as small as possible.
3. It can be seen from the impact resistance times: determine the service life of the lightning arrester. Under normal circumstances, the gas discharge tube will not fall for a period of time. If you want to test its quality, you can use an adjustable high-voltage DC power supply . test.
Generally, the quality of the lightning arrester is judged from these three indicators. If the lightning arrester is very close to the electrical equipment (assuming the electrical distance L = 0), then the residual voltage of the lightning strike equipment is equal to the lightning protection Device residual pressure, the lower the residual pressure, the safer the equipment being protected
Stainless Steel Grinding Ball is an important basic parts, especially precision industrial steel ball plays a huge role in the development of national economy. Under some special conditions, special steel balls are often needed to achieve the functions required in different environments. In fact, some special steel balls have been widely used in various fields of national economy. Their popularization and application not only promoted the development of steel ball manufacturing industry, but also promoted the technical development and technological progress of related industries.
