Industrial control chassis manufacturers tell you the service life of server chassis!

As the temperature rises, everyone will immediately enter the summer. Summer is full of storms, and lightning protection is very important for server chassis. So how critical is lightning protection?

This is a problem that everyone has mastered. Since childhood, everyone has learned that lightning can cause the destruction of home appliances. In the construction of the house, a lightning rod will be installed to introduce the lightning to the bottom to reduce the damage of the lightning, then everyone's server chassis What will manufacturers do in response to lightning?

AC power lightning arrester: According to the different working voltage, it is often divided into single-phase power lightning protection and three-phase power lightning arrester. When the power surge protector is connected to the transmission line, it can resist transient overvoltage and release surge current. According to different requirements, various power arresters such as "pluggable control module type", "terminal wiring type" and "mobile socket type" can be used.

There are some electrical components placed in the server chassis. This kind of machinery and equipment must be powered by power. Therefore, it is very important for everyone to protect the power supply of the server chassis from lightning. This also has the appearance of the power surge protector. According to the characteristics of maintaining the power supply Divided into communication AC power surge protector and high voltage DC power surge protector.

The lightning protection of electronic devices and electrical equipment should mainly avoid the damage to the machinery and equipment caused by the magnetic induction overvoltage and overcurrent caused by the lightning electromagnetic induction. Great attention should be paid to lightning protection on the power line. Statistical analysis shows that electronic devices and electrical equipment are struck by lightning, and more than 70% to 80% of them are caused by the intrusion of magnetic induction lightning waves along the power line. Therefore, the power line lightning arrester Lightning should be the top priority of lightning protection for electronic devices and electrical equipment.

Generally, three-level maintenance is used, that is, the first-level power surge arrester is installed in the server chassis to which the electronic product belongs, and the second-level power surge arrester is installed at the sub-power supply of the building or house to which the electronic product belongs. Develop (such as before UPS or power socket) install a three-level maintenance power arrester.

The lightning protection of the server chassis must be deployed layer by layer, gradually separating the current limiter and charging and discharging, and gradually clearing the lightning energy to ensure the safety of electronic devices and electrical equipment.
