Switching power supply rj45 wall socket is the use of modern power electronics, control switch turn-on and turn-off time ratio, maintaining a stable output voltage of the power supply, switching power supply in general compared to the pulse width modulation control IC switching power supplies and linear power supplies, two With the increase of the costs to both the output power and increase the growth rate but they are different. Linear output power costs on a power point, but higher than the switching power supply, which is called the cost of turning points. With the development of power electronics technology and innovation, making the switching power supply technology is also constant innovation, the cost of reversing the growing point moves to low output power terminal, which provides a broad space for development of the switching power supply rj45 wall socket
A modern communications switching power supply to achieve unattended, all with remote monitoring capabilities, such as remote telemetry, remote control, and signal line interface to communicate with associated long distance, extremely vulnerable to lightning damage and downtime caused by accidents , Ministry of Information requests should be protected in accordance with the installation of the appropriate signal mine.
Two. Installation of DC mine was recently released in lightning protection standards put forth, because the residual pressure is much lower than the current exchange mine mine, so they can effectively improve the communication switching power station sensitive equipment against lightning the ability of electromagnetic pulses.
Three. Mine capacity and installation of lightning protection is closely related to the main rj45 wall socket is lead inductance will generate additional residual voltage, power lines should be as short as possible connection with mine and mine with ground sinks adapter plate connection length.
Four multi-level arrangement of lightning can reduce lead inductance bring additional residual pressure, as have most of the pre-lightning lightning current into the ground, in the level of lightning discharge is only a small part of the mine current, reducing the lightning current will inevitably lead to an additional reduction in the residual pressure on the lead. To ensure the energy level with the front of mine, power cable length between the SPD should not be less than 15 meters, or should adopt decoupling device for energy cooperation.
V. Bureau of lightning into the power cable is easy to pay attention to, and the other out of the power line communication stations are often overlooked, such as street lighting lines, power line tower lights, non-telecommunications facilities leased telecommunications, electric power lines. Now should adopt solar tower lights can reduce a lightning invasion of channels. Other out power lines should be in the range of lightning protection system, or should take special measures against lightning.
