Signal surge protector manufacturer: lightning protection device is mainly used to prevent lightning strike and ensure the safety of equipment. However, after many customers install lightning protection device, lightning protection device and equipment damage will also occur. What skills should lightning protection device have to avoid these problems as far as possible?

Signal surge protector manufacturers talk about the selection of lightning protection device should have what skills?

Signal Surge Protector Manufacturers: What Skills Should Lightning Protector Selection Have?

Signal Surge Protector Manufacturer: 1. Confirmation Power Supply System

First of all, IT needs to determine what your power distribution system is like, TT,TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring mode of the lightning protector and choose the appropriate lightning protector.

For example, TN-C uses 3P lightning protection device, TN-S uses 4P lightning protection device, TT uses 3P N lightning protection device, etc.

Signal Surge Protector Manufacturers: 2. Understand the Main Parameters of Lightning Protector

(1) Nominal voltage Un: The additional voltage of the system to be maintained is consistent. In the information technology system, the parameter table specifies the type of maintenance personnel to be selected, and it marks the effective value of communication or DC voltage. (2)Z continuous voltage Uc: the Z large effective value of the voltage that can be permanently applied to the specified terminal of the lightning protection device without changing the characteristics of the lightning protection device.

(3) Nominal discharge current in: Apply 8/20s standard lightning wave to the lightning arrester 10 times, and the lightning arrester will not be damaged.

(4)Z discharge current Imax: the peak value of Z large strike current that the lightning protection device can withstand when the lightning protection device is impacted by a standard lightning wave with a waveform of 8/20 s.

(5) Voltage protection level Up: the voltage protection level of the lightning arrestor in good condition.

When selecting the lightning protection device, Uc should meet the system voltage, the flux should meet the use requirements, and the protection level should be lower than the equipment withstand voltage.

Signal Surge Protector Manufacturers: 3. Look at the Strength of Lightning Protector Manufacturers

When choosing lightning protection products, we should choose products with lightning protection test reports, and the safety functions are guaranteed. When choosing manufacturers, we should pay attention to the strength of manufacturers, and try to choose manufacturers with many years of lightning protection experience to ensure the after-sales operation of lightning protection products.

Signal surge protector manufacturers: 4. select lightning protection devices that meet the conditions specified by law.

Nowadays, lightning protection manufacturers emerge one after another, but many manufacturers do not have the legal and regulatory conditions for the production of lightning protection devices, and lightning protection devices have not been tested and certified, and the market is not enough, so the quality and safety functions are not guaranteed, so more attention should be paid to the selection of lightning protection devices.

The above is the signal surge protector manufacturers Xiaobian to explain the selection of lightning protection should have the relevant knowledge of what skills, we have learned.
