Product Description
KM-DBP low voltage surge protector
One. Product introduction
KM-DBP low-voltage combination of integrated instantaneous overvoltage protector (also known as new surge protector) series products according to GB18802.1-2002 (IEC61643-1) design, its core components using the company's high-quality chip/discharge gap.
100% through the selection of voltage capability, current capability and abnormal parameters. KM-DBP maximum flow rate can be large 200KA (8/20us), withstand overvoltage capability, low residual voltage and small leakage current. The release mechanism is sensitive, standard rail installation (35mm), failure window display, fast response, to ensure safe and reliable.
Two. Selection explanation
In order to ensure correct protection for specific applications, according to the international standard IEC 61662, the following main factors should be taken into account in choosing the low-voltage integrated instantaneous overvoltage protector.
The degree of danger of lightning strikes in the geographical area and underground area of the building.
The value of protected equipment and its economic losses after destruction;
Personnel density and corresponding safety requirements;
The shape of a building. Volume. Height and environment.
Three. Scope and product type
1. The power gap series is suitable for equipotential bonding in the low voltage side of the transformer or in the low voltage main distribution box of the building to protect the overvoltage of the first pole of the power supply or the overvoltage caused by the operation. The front end of this series must be connected in series with fuses, otherwise, the power frequency freewheeling generated during the discharge of the product may burn the protector.
2. The B-class series is suitable for AC 50/60HZ, 380/420V power supply systems. It provides first-level lightning (overvoltage) protection as a low-voltage total distribution system for building incoming lines.
3. C-class series products are suitable for AC 50/60HZ, 220/380V power supply systems. It can be used as the second-level lightning protection for distributed electricity in buildings, such as distribution cabinets for high-rise buildings and units for distribution of electrical buildings.
4. Class D series products are suitable for lightning protection or overvoltage protection of AC 50/60HZ, 220/380V power supply systems, such as information network, smart equipment, civic buildings, etc.
5. The ground protection system is mainly used to avoid the danger of electric potential differences between different grounding grids. When lightning strikes, the potential of one of the grounding grids is raised to a very high level in an instant, resulting in a high potential difference between the grounding grid and other grounding grids. The potential difference may be connected to the network of lines or devices between different ground poles, that is, ground potential counterattack, which poses a great danger to the safety of equipment and personnel. In this case, it is necessary to install a pole protector between different ground networks to avoid ground potential counterattack problems.
6. The DC power supply series lightning protection device is used for the front end of equipment of different voltage supply lines such as computer system, modem, signal control, etc., and protects against overvoltage caused by the lightning strike of the DC power supply line or operation overvoltage.
Four. General installation rules
Adopt 35mm guide rail to install.The protector is installed in parallel with the input end of the device.200KA. 150KA, 120KA, 100KA series are connected by connecting pieces at the lower end of the module. 80KA, 65KA, 40KA, 25KA, 15KA are composed of the base and module.The upper end of the protection module is respectively connected with the phase line L `zero line N. Grounding wire PE, and the module connected with the PE terminal is repeatedly connected with the earth.For maintenance inspection, enhanced backup protection can be connected in series with a set of three-phase/single-phase fuses (fuses) at the front end of the protector.

Seven. Solar photovoltaic installation low voltage combined integrated transient overvoltage protector
1.Protect solar photovoltaic facilities effectively.
The professional lightning surge protector device is the basic guarantee for the reliable operation of solar photovoltaic.
Solar photovoltaic installations are always at risk of direct lightning strikes and inductive lightning. The necessary protective measures must be taken to ensure their safety and reliable operation.
2. All metal structures of the equipotential bonding facility must be interconnected and grounded effectively to achieve an equipotential bonding.
3.Comprehensive protection
Both DC and AC lines require the installation of protective devices, and the DC section may be subjected to partial direct lightning currents. Therefore, you should consider installing a primary protection (TYPELDS60PV)
4. Buried cable
If possible, the cable between the photovoltaic module array and the inverter should be buried in a metal pipe and the cable should not be coiled to reduce the risk of direct lightning strike and inductive coupling.
5. Installation location
If the cable length between the photovoltaic module array and the inverter is greater than 30 meters, a protective device should be installed at one end of the photovoltaic array.
6. Other cable protection
The protection of other lines is equally important, such as motor inputs, sensors, probes, data lines, etc.

Eight. Wind power lightning surge protector
With the shortage of international energy, opening up and utilizing new energy sources has become a basic requirement for increasing competitiveness.
At present, wind power generation is less than 1% of the world's power generation, with 1.7 million jobs in wind power technology, 10 billion tons of carbon dioxide emissions reduced worldwide.
Because the wind farm is in an open area, it is vulnerable to lightning strikes during lightning storms, and the electric equipment of the wind farm is also affected by inductive lightning and lightning waves.
According to the law of lightning activity of wind farms, combined with the leading lightning protection products and technology of German PHOENEX, the products for lightning protection and surge protection of wind power boxes are introduced, so that the box and its subsequent equipment were protected primarily even in thunderstorms.
