How to install the lightning protection device ? It is believed that many engineering personnel do not know how to use the power supply lightning protection device and feel very anxious about the power supply lightning protection device. Now let Xiaobian give you a brief introduction. In general, the installation of power SPDs needs to pay attention to the following nine points:
1. The power surge protector must be installed through a 35mm rail.
2. The phase wire of the power supply cable should be connected to the “L†wiring hole of the power SPD, and then the neutral wire of the power supply cable should be connected to the “N†wiring hole of the power SPD, and finally from the power SPD. The "PE" wiring hole leads to the grounding wire connected to the lightning protection grounding bar or the lightning protection grounding bar.
3. The minimum cross-sectional area of ​​the connecting wire of the lightning arrester shall comply with the relevant provisions of the national lightning protection project.
The first-level switch-mode 10/350us power surge protector should not be less than 16mm2 copper conductor.
The second-stage limiting type 8/20us power surge protector should not use less than 10mm2 copper conductor.
The third-level limited-voltage 8/20us power surge protector should not be less than 6mm2 copper conductor.
The fourth-level limiting type 8/20us power surge protector should not use copper conductors of less than 4mm2.
4. When installing the lightning protector, you must disconnect the power supply before installing it to avoid accidents!
5. The power supply lightning protector can provide the remote communication interface according to the needs of the project. "COM" is the neutral point, "NC" is the normally closed point, and "NO" is the normally open point.
6. When the red indicator of the power surge protector is displayed in red, it means that the existing components in the power protector are damaged, which may cause the lightning protector of the power supply to have poor lightning protection effect and must be replaced immediately.
7. When the length of the line between the switch type SPD and the voltage limiting SPD is less than 10m and the length of the line between the SPD is less than 5m, decoupling should be installed between the two SPDs. Device.
8. The connection wire of the power surge protector should be straight, and the sum of the wiring length of the power surge protector to the power cord and the wiring length of the power surge protector to the equipotential connection device should be less than 0.5m.
9. If the requirement of 0.5m cannot be achieved, Kevin wiring can be used.
AM-100 three-phase power surge protector is mainly applied to the total power supply. Such as power distribution room, distribution cabinets, and Other important places as a total power supply as a Class I (Class B) lightning protection. It is widely used for main power protection of mobile communication base stations, microwave communication stations/stations, telecommunication rooms, factories, civil aviation, finance, securities and other systems.
Features:
â– Meet the national GB18802.1-2011/IEC61643-1:2005 standard and YD/1235.2-2002 product design and test standards.
â– Built-in overheating and overcurrent protection tripping device ensures that the lightning arrester can be automatically disconnected from the power grid in the event of an accidental failure, so as to avoid a fire caused by the short circuit of the power line, and to be flame-retardant and explosion-proof.
â– Using strict current sharing technology, it can withstand continuous and multiple shocks.
â– The remote alarm function enables remote monitoring of the working status of the lightning arrester, making it easy to implement unattended, safe and reliable.
â– Kevin type (V type) wiring can be realized to ensure the best lightning protection effect.
â– Use red/green window to indicate working status, clear and intuitive.
â– Small size, large flow capacity.
â– Single-piece structure, free combination, small installation space.
â– Optional lightning counter to accurately record the number of lightning strikes.
â– The core components use international famous brands and have excellent performance.
