Product Description

 

 

 

Power supply lightning protector (SPD), also known as lightning arrester, surge protector, surge protector. In the information age, computer networks and communications equipment is increasingly sophisticated, the requirements of its working environment is also increasingly high, and lightning and large electrical equipment transient overvoltage will be more and more frequent through the power supply, antennas, radio signal transceiver equipment and other lines into the indoor electrical equipment and network equipment, resulting in equipment or component damage, casualties, transmission or storage data interference or loss, and even make electronic equipment malfunction or temporary paralysis, system stoppage, data transmission interruption, LAN or even WAN damage. The damage is alarming, and the indirect loss is generally much larger than the direct economic loss. Power supply lightning protector is to prevent equipment from being struck by lightning through modern electricity and other technologies.

Development history Editorial voice
The most primitive lightning arrester is ram-horn shaped gap, appeared in the late 19th century, used for overhead transmission lines, to prevent lightning damage to equipment insulation caused by blackouts, so called "lightning arrester". 1920s, aluminum lightning arrester, oxide film arrester and pill arrester appeared. 30s appeared tubular lightning arrester. 50s appeared silicon carbide lightning arrester. 70s appeared metal oxide lightning arrester In the 1970s, metal oxide lightning arrester appeared. 1992 onwards, the industrial control standard 35mm rail snap-in pluggable SPD lightning protection module, represented by Germany and France, began to be introduced into China on a large scale, and later the integrated box power lightning protection combination, represented by the United States and the United Kingdom, also entered China.

Performance features
1. large protection flux, very low residual voltage, fast response time
2. the latest arc extinguishing technology, completely avoiding the occurrence of fire
3. Adopt temperature control protection circuit, built-in thermal protection
4. with power status indication, showing the working status of the surge protector
5. Rigorous structure, stable and reliable operation [1].

 

The difference between surge protectors and lightning arrestors Editorial Voices
Lightning arrester
1, lightning arrester has a number of voltage levels, from 0.38KV low voltage to 500KV extra high voltage are available, while surge protectors are generally only low-voltage products.
2, lightning arrester more installed in the primary system to prevent the direct intrusion of lightning waves, and surge protector more installed in the secondary system, is in the lightning arrester to eliminate the direct intrusion of lightning waves, or lightning arrester does not eliminate lightning waves when the supplementary measures;.
3, lightning arrester lightning arrester is to protect electrical equipment, and surge protectors are mostly used to protect electronic instruments or meters;.
4, lightning arrester due to the connection of the electrical primary system, to have sufficient external insulation, the appearance of the size is relatively large, while the surge protector due to the connection of low voltage, the size of the production can be very small.
Surge protector
1, must be retrofitted with inverter control cabinets
2, the use of vacuum circuit breakers in the control cabinet must be retrofitted with vacuum circuit breakers
3, the power supply system must be added to the incoming switch
4, other control cabinets can not be added, of course, if the budget space is large, for insurance purposes can be added.
Surge protector is generally divided into two categories: motor protection type, power station protection type, in the selection must pay attention to [3] .
