What Is a Battery Backup with Surge Protector?

Power surge protector, also known as power lightning arrester, is suitable for AC 50 / 60HZ, rated voltage 220V / 380V power supply system, to protect against indirect lightning and direct lightning effects or other transient overvoltage surges, suitable for home The requirements for surge protection in residential, tertiary industries, and industrial fields include relative phase, relative ground, relative midline, neutral line to ground, and combinations of protection modes.

Power surge protector is suitable for TT, TN-S, TN-C, IT and other power supply systems and factory low-voltage power and control systems with AC 50 / 60Hz and rated operating voltage 220V / 380V, which affect indirect lightning and direct lightning or other Protection against transient overvoltage surges, mainly applicable to surge protection requirements in residential, tertiary industry and industrial and mining enterprises ^[1]

The power surge protector is usually connected in parallel to the circuit system. When lightning occurs, the high-intensity electromagnetic induction generated on various metal pipes and lines entering the building will generate a large amount of pulse energy, and the power surge protector will Play a role in introducing overcurrent to the ground, reducing the potential difference between the ports of the device. Suitable for 220 / 380V power supply and distribution system transient over-voltage protection. This product can effectively suppress the induced over-voltage and system operating over-voltage caused by lightning, protect the safety of equipment and ensure the normal operation of the system.

lightning arrester

1. Lightning arresters have multiple voltage levels, ranging from 0.38KV low voltage to 500KV ultra high voltage, while surge protectors generally have only low voltage products;

2. Lightning arresters are mostly installed on the primary system to prevent direct intrusion of lightning waves, while surge protectors are mostly installed on secondary systems. After the lightning arresters have eliminated the direct intrusion of lightning waves, or the lightning arresters have not eliminated the lightning waves Supplementary measures

3. Lightning arresters are used to protect electrical equipment, while surge protectors are mostly used to protect electronic instruments or meters;

4. Since the lightning arrester is connected to the electrical primary system, it must have sufficient external insulation performance and a relatively large size, while the surge protector can be made small because it is connected to a low voltage.

Surge protector

1.Inverter control cabinet must be added

2.The control cabinet using vacuum circuit breaker must be added

3. The incoming switch of the power supply system must be added.

4, other control cabinets can be omitted, of course, if there is a budget space for insurance purposes, they can all be added

Surge protectors are generally divided into two categories: motor protection type and power station protection type must be paid attention to when selecting ^[3] .
