How To Protect UPS In Thunderstorm Weather
- Jul 16, 2018 -

For the lightning protection of UPS power supply system and communication port, it is necessary to work out feasible solutions according to the specific conditions of the application environment and local conditions, and establish an effective, scientific and economic lightning protection system. According to the characteristics of UPS system, its lightning protection should focus on the following points:

 

1世界杯预选赛竞猜 The external lightning protection facilities shall be improved and the machine room shall be well grounded. According to the code for design of electronic computer room, AC, DC working ground, protective ground and lightning protection ground shall share a group of grounding devices, and the grounding resistance shall be determined according to the minimum value. If the grounding must be set separately, equipotential common ground coupling must be installed between the two places. UPS protection is often a large data system, which is more sensitive to lightning counterattack. Even if the potential counterattack is very small, it often causes unnecessary losses.

 

2世界杯预选赛竞猜 Choose the arrester. The market of this kind of products is relatively rich at present. Try to choose the arrester with good reputation and reliable quality. The ground wire of the arrester should be no less than 6mm2, connected with the shortest lead. In the connection mode, it is better to use Kevin connection mode to minimize the induced voltage on the lead.

 

The special lightning protection boxs for in power supply and UPS power supply must be grounded, the lightning arrester and UPS power supply shall be equipotential connected, and the ups output line shall be grounded. It is better to use high-quality grounding module in the grounding system, which can ensure the reliability and corrosion resistance of the grounding resistance, and avoid the transformation of the grounding grid every 1-2 years, saving the cost for the user.
