Time: 2019-11-08 Browse times: 198

Ethernet is everywhere in life, for example, telecommunication backhaul routes, computing connections for industrial networks. Ethernet has become the main communication standard in the electronics industry. Ethernet communication signal lines are often impacted by the inrush current generated by the electromagnetic interference of high-voltage cables around it, which may lead to inaccurate data transmission in Ethernet communication, and the risk of Ethernet interface burnout. This requires advanced protection solutions. These interfaces provide adequate protection from various overvoltage hazards. An Ethernet surge protector is recommended.

Ethernet surge protection

Ethernet surge protector is a surge protector specially designed for Ethernet (Local Area Network). Product input and output adopt RJ45 male / female connector, which is convenient to connect and simple to install. It is mainly used for server, workstation (internal local area network), HUB, and broadband RJ45 interface protection to prevent equipment from rising due to ground potential or line induced overvoltage. Damage.
1. Convenient selection and worry-free acceptance:
At present, the acceptance of surge protectors in building power is mainly to check whether the parameters of the surge protectors installed in the main power distribution cabinet and the final-stage power distribution box meet the national standard requirements:
1) T1 test surge protector shall be installed in the main power distribution cabinet. The main parameters shall be Iimp≥12.5kA, Up: ≤2.5kV.
2) The last-stage power distribution cabinet needs to be installed with a surge protector with Up≤1.2kV.
The product parameters are all the requirements for the acceptance of the surge protector of the main distribution cabinet and the final distribution cabinet, and the type test report obtained. When selecting the type, there is no need to consider the parameters such as the flow capacity and protection level of the surge protector Select 3P, 2P according to three-phase / single-phase, it can be used in all positions.
2. Voltage-limiting type first-level lightning protection design, no freewheeling, tripping, and more:
This product is a T1 test (10 / 350us) first-level lightning protection product, designed to be used between LPZO and LPZ1 (according to the definition of lightning protection area in GB50057-2010), in accordance with the national standard GB50057-2010 4.2.4 paragraph 8 : A surge protector of class I test (10 / 350us) should be installed at the main distribution box where the power supply is introduced. The voltage protection level of the surge protector should be less than or equal to 2.5 kV. When it is impossible to determine the inrush current value of each protection, the inrush current shall be equal to or greater than 12.5 kA. At present, most of the products in the industry's class I test (T1) surge protectors are switch-type designs with graphite gaps or discharge tubes. The switch-type first-class (T1) surge protectors have the risk of freewheeling and there is basically no heat. Trip protection function; This product is a pressure-limiting design, no freewheeling, thermal trip protection function, higher product performance;
