Tower Backup Power Supply
The emergency backup power supply system of the base station uses the battery as the backup power supply. The load power supply to be guaranteed is switched between the switching power supply and the emergency system through the automatic switch. When the base station is powered off, the backup battery of the system does not participate in the discharge. When the secondary power tripping of the switching power supply is detected, the emergency backup power supply system will be put into use immediately to ensure the continuous power supply of important equipment. This set of system is placed on a shared site, which can guarantee network differentiation and maintain the network leading edge of mobile companies. It can reduce the maintenance cost of the backup battery and ensure the power supply duration of important transmission equipment by placing it at the reserved site.

3、Determine the design scheme
Most People Ask :
The UPS that is best for you will depend on the following factors:
The power problem you are trying to avoid (see the previous section)
The number of electronic devices you want to support through the UPS.
The wattage of the electronics you are connected to the UPS.
How long or running time do you need the backup battery to run.
Add the total wattage to determine how much power your home might use during a power outage. Divide the total wattage by 1000 to get kilowatts. Multiply by kW x 1.25 to increase the margin of safety and meet future power demand. This is the minimum generator capacity required for your home.
How to confirm the scheme design of wind tower standby power supply equipment?
Quick confirmation of several major steps in the scheme design of standby power supply equipment for mobile phone signal tower
1、Communicate needs with engineers
2、Review the design scheme
3、Determine the design scheme
Most People Ask :
Wind turbines with blades and horizontal shafts. Common horizontal axis wind turbine models use three blades, which is the most effective solution.
The purpose of the Wind Energy Conversion System (WECS) is to convert wind energy movement into mechanical energy. With the help of a wind turbine generator, this mechanical energy is converted into electrical energy. In a windmill, this energy is used to do work, such as pumping water, milling grain or driving machinery.
How do I select components for the tower backup power supply?
Three points to ensure rapid procurement of spare power supply equipment components for mobile phone signal tower
1、Click to consult
2、Contact the Engineer
3、Confirm requirements
Most People Ask :
You can use the following simple formula:
Standby time (hours)=battery capacity (Ah) X input voltage (V)/total load (W)
If the battery capacity is 110Ah:
If the battery capacity is 220Ah:
If fully charged, you can expect your 150 Ah battery to last about 3 hours under a 400 watt bulb load. If the load or device power decreases, backup will be improved.
How does the tower backup power supply work?
Three points to ensure the safe operation of standby power supply equipment of mobile phone signal tower
Most People Ask :
Most cell phone towers have some form of backup power. When they lose power, they turn to the battery. If the batteries run out, the towers get power from fuel dependent generators. These methods can provide power for several days or more, depending on whether the generator can be refueled
These backup power rules are currently being challenged by CTIA and other entities, requiring each cellular site to have 8 hours of backup power.
Most have permanent generators that can operate on one tank for 24 to 72 hours. The vast majority of sites without portable generators can use portable generators, but cannot access the “discrete part” of the network.
How to detect the quality of tower standby power supply?
Key quality points of standby power supply equipment for N mobile phone signal tower
1、Complete and pass the test required for the energy storage equipment.
Most People Ask :
The easiest way to diagnose this problem is to smell the power supply after turning it off and disconnecting it from the AC power supply. If you can smell the burning smell with chemical overtones from the external vent of the power supply, your power supply has failed.
Power element The power switching element or MOSFET is the primary force for power supply operation. If the heat dissipation is insufficient, or the drain over-voltage, drain over-current, grid over-voltage or internal anti parallel diode, sometimes it will lead to failure. Excessive pressure.
How to choose the transportation and packaging method of tower standby power supply equipment?
2 points to ensure the safety of transportation and packaging of standby power supply equipment for mobile phone signal tower
1、Complete and pass various transportation tests
2、Reinforce the packaging of household transport equipment
Most People Ask :
Whenever a mobile phone is used, it will emit an electromagnetic radio wave called radio frequency, which is received by the antenna of the nearest mobile phone signal tower. Once the cellular tower receives this signal, it will transmit the signal to the switching center.
On average, the maximum usable range of mobile phone towers is 25 miles. Although the typical coverage radius of a cellular tower is 1 to 3 miles, and in a dense urban environment, a cellular tower typically reaches 0.25 to 1 mile before connecting users to another nearby cellular site.
On average, a cellular tower allows about 30 simultaneous voice calls and 60 simultaneous 4G data users.
How to install the tower backup power supply?
Three common installation methods of standby power supply for mobile phone signal tower
Most People Ask :
What is the correct procedure for connecting the UPS to the computer? There is no specific procedure. You just plug the power cord of the PC and the screen into the UPS, then plug in the UPS, turn it on, turn on your computer, and you can start using it.
Most cell phone towers have some form of backup power. When they lose power, they turn to the battery. If the batteries run out, the towers get power from fuel dependent generators. These methods can provide power for several days or more, depending on whether the generator can be refueled.
The average cellular base station, including the tower and the radio equipment connected to it, can be used anywhere from 1 to 5 kilowatts (kW), depending on whether the radio equipment is installed in an air-conditioned building, the service life of the tower and how many transceivers are in the base station.
