A power supply method for iron towers based on differentiated power backup equipment

Abstract

The invention provides a power supply method for iron towers based on differentiated power backup equipment, relates to the field of power tower backup, and can meet the power backup needs of original backup batteries and crude oil generators after adding 5G equipment from different operators to base stations. The power supply method of the iron tower includes the following steps: Step 1. After the mains supply is interrupted, N pieces of backup power supply are discharged to supply power to X devices, N≥2, X≥2; Step 2. Turn off M pieces of backup power alternately, start the generator to Among them, Y devices supply power, and the remaining N‑M backup power supplies supply power to the remaining X‑Y devices, Y≥1, M≥1; Step 3: The backup power supply reaches the primary power-off voltage, and enables differentiated backup power supply to X devices Power supply; step 4, when the mains power supply is restored, the mains power is used to supply power to X devices, and the mains power is also charged to N spare power sources. In the present invention, part or all of the M backup power supplies alternately correspond to the number of N-M backup power supplies, and the generator is used to supply power to Y devices, which can extend the backup time.

Description

technical field [0001] The invention relates to the field of iron tower power supply, in particular to a method for iron tower power supply based on differentiated power backup equipment. Background technique [0002] From 2002 to 2006, China Mobile, China Telecom, China Unicom, China Netcom, and Tietong invested a total of 1.1235 billion yuan in infrastructure construction. The problem of repeated investment is prominent. The utilization rate of network resources is generally low, and the utilization rate of communication optical cables is only 1. / 3 or so. The call for resource sharing among operators followed. [0003] Under the background of implementing the strategy of "network power" and promoting the sharing of telecommunications infrastructure resources, telecommunications tower infrastructure service companies emerged as the times require. In 2014, the Iron Tower Company was established. The Iron Tower Company is mainly engaged in the construction, maintenance, an...
