Three-in-one lightning protector use:

1. Please look for the interface and connection method;

2. Look for the input and output interface identification of the lightning protection device, and the input connection to the external line and the output connection equipment;

3. The grounding wire should be short, thick and straight to reduce the influence of the distributed inductance on the discharge of lightning electromagnetic pulse ability;

4. The grounding of the signal lightning protector should be connected to the ground network through the electronic switch.

The principle of the three-in-one lightning protector is as follows:

It is used in parallel on power supply lines and signal transmission lines with a combination of overvoltage protection electronic devices that present a high-resistance open-circuit state at low voltage and a low-resistance short-circuit state at high voltage, and can withstand hundreds of amperes of high current. When encountering Zen bright lightning strike and high voltage and high current, it immediately presents a short circuit, and at the same time disconnects the main power switch, so that the computer equipment is protected. A tandem installation is used only when it is in the form of a physical surface.

Signal lightning protection devices are required to have low loss of high-frequency signals.

The above is to introduce to you the relevant introduction to the use of the three-in-one lightning protector and its principle, I believe you have a deeper understanding of the three-in-one lightning protector. In short, the 3-in-1 lightning protector is a surge protection that can protect the camera of the monitor pan tilt from damage due to excessive voltage and electrostatic discharge. It is suitable for all kinds of airports, buildings, military bases and other public places.

The differences between the primary and secondary lightning protectors are as follows:

1. The current capacity of the first stage is different from that of the second stage, generally the overcurrent capacity of the first stage is much greater than that of the second stage, the first stage is mainly used for discharge, and the second stage is mainly used for voltage limiting.

2. The reaction time of the first stage is different from the second stage, and generally speaking, the switching type of the first stage SPD is slower than that of the limited voltage type.

3. The level of protection of the first level and the second level is also different, the first-level SPD can protect 100KA of lightning waves, while the second-level SPD can only protect 40KA of protection.

4. The installation position of the first level and the second level is not the same, generally speaking, a house, the first stage is installed in the distribution cabinet of the three-phase electric incoming line, and then the second level is installed on each floor.

The complete lightning protection system is divided into the following five parts according to different functions:

1. Direct lightning protection: prevent lightning from directly hitting buildings, structures, electrical networks or electrical installations. The first part of the macro differential lightning protection system is to protect the building itself from lightning damage and to reduce the impact of the huge lightning current that leaks along the building into the ground during lightning strikes.

2. Grounding: an intentional or unintentional conductive connection, because of this connection, the circuit or electrical equipment can be connected to the earth or connected to the earth to replace the earth, a larger conductor.

3. Equipotential connection: It refers to the connection of separate metallic objects directly to the lightning protection device with a connecting conductor or a surge protector to reduce the potential difference caused by lightning current.

4. Electromagnetic shielding: the shielding that uses conductive materials to reduce the penetration of alternating electromagnetic fields to the specified area. The lightning electromagnetic pulse is centered on the lightning strike point and spreads to the surrounding area, and its impact range can reach 2 kilometers or even beyond, not only limited to the lightning strike building itself or its internal equipment.

5. Overvoltage protection: refers to a kind of protection applied by the power supply device and the connected equipment to prevent the power supply from failing to produce excessive output voltage. <>

To put it simply.

The 3-in-1 is for cameras with gimbals, that is, rotations.

The two-in-one is a given point, that is, it is used for the four heads that do not move.

Three-in-one lightning protection device, also known as three-in-one surge protector, three-in-one lightning arrester, monitoring multi-functional lightning protection box, refers to the lightning protection equipment integrating signal lightning protection and power lightning protection at the camera end of the monitoring system.

Let's start with the devices that are protected. Secondly, it depends on the size of the power supply of the device, the interface, and there are too many factors. There's no end to it!

The selection of power surge protector is indeed related to the on-site environment, depending on whether you want to apply it to the world. Generally speaking, the first thing to consider is the external environment, whether it is in the urban area or suburbs, or in the mountains, whether there are overhead wires to guide the way, so as to select the important parameter index of the first level of lightning protection - the maximum flow rate; Second, it is necessary to check the category of the power supply system in the building, whether it is single-phase power supply or three-phase power supply, so as to choose whether the lightning protection device is three-phase or single-phase; Third, it is necessary to check whether the power supply environment is bad and whether the power supply voltage is stable, so as to determine another index parameter of the lightning protection device - the maximum continuous working voltage; Fourth, it depends on whether you need additional alarm functions, which can be customized, and finally it is necessary to consider the protection of the circuit when the lightning protector itself is damaged and produces a short circuit, which can be based on the capacity of the backup protection air switch.
