Product Description

Network voltage 900Vdc PV Surge Protector , Symmetrical rail 35 mm Mounting

 

OBV5-C40-PV

 

Prewired modular complete unit for use in photovoltaic systems consisting of a base part and plug-in protection modules

Combined disconnection and short-circuiting device with safe electrical isolation in the protection module prevents fire damage resulting from d.c. switching arcs (patented SCI principle)

Tried and tested fault-resistant Y circuit of the OBV6-C40-PV prevents damage to the surge protective device in case of insulation faults in the generator circuit.

Integrated d.c. fuse allows safe replacement of protection modules without arc formation.

Note: The system lightning protection does not guarantee that the equipment will not be 100% damaged by lightning; the power system must be multi-level lightning protection;
The complete lightning protection system includes external lightning protection and internal lightning protection. External lightning protection refers to: lightning receptors, down conductors, and grounding bodies, which are mainly used to defend against direct lightning strikes. Internal lightning protection includes: shielding, reasonable wiring, safe distance, equipotential connection, overvoltage protection, etc., mainly used to prevent lightning induction, ground potential counterattack, lightning wave intrusion, etc.


Application


●AC/DC distribution
●Power supplies
●Industrial automation
●Telecommunications
●Motor controls systems
●PLC applications
●Power transfer equipment
●HVAC applications
● AC drives
●UPS systems
●Security systems
●IT/Data centers
 

Tip: Lightning protection is probabilistic protection, and we cannot provide 100% protection.


First, lightning discharge itself has a certain degree of randomness, and lightning parameters have certain statistical properties, which determines that all protective measures based on these statistical characteristics of lightning parameters cannot provide 100% protection. Such as: direct lightning protection-shielding characteristics; lightning current amplitude, waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all interference voltages/currents. The fundamental purpose of taking protective measures is to ensure that most of the energy caused by interference does not spread to the vulnerable parts of the device and the staff.
Finally, the cost of protection against high-level surges with a small probability of occurrence has risen sharply.

 

One easy solution


With this solution, many cells in power plant and residential application have been protected. If you don't protect your cells, in case of several big surges, your cells will be completely damaged and in case of many small surges without visual damages for you, your effciency will go down over the years. You should use a surge protection to have a better return on investment. Class C surge protection for photovoltaic

OBV5-C40-PV DC series are Class C Surge Protection Devices, they designed to protect against lightning surge voltages in photovoltaic power supply networks. These units must be installed in parallel on the DC networks to be protected and provide common and differential modes protection. The OBV5-C40-PV DC series are availa-ble for the main operating voltages in photovoltaic : 500, 600,800,900 and 1000 Vdc. The use of Class C Surge Protection Devices are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long. The electrical diagram of the OBV5-C40-PV DC series are based on high energy MOVs equipped with specific thermal disconnectors and related failure indicators. A remote signal feature is also available
The OBV5-C40-PV DC series are made with plug-in modules to allow a fast and easy maintenance in case of fa-ilure (disconnection from the DC network).

Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.

 
What skills should lightning protectors have in the selection?
 
1.Confirm power supply system
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
 
2.Know the main parameters of the lightning arrester.
