Distribution transformer monitoring system based on 230M-LTE network

Abstract

The invention discloses a distribution transformer monitoring system based on a 230M-LTE network. According to the technical scheme, the distribution transformer monitoring system comprises a power supply sampling module, a multifunctional electric meter, a distribution transformer monitoring terminal, a 230M-LTE wireless collector and a wireless data receiving and transmitting module, wherein the multifunctional electric meter is connected with the 230M-LTE wireless collector; the input end of the power supply sampling module is connected with the high-voltage side or the low-voltage side of the transformer, and the output end is connected with the wireless data receiving and transmitting module; the wireless data receiving and transmitting module and the 230M-LTE wireless collector are used for remotely transmitting power information to the distribution transformer monitoring terminal through a TD-LTE230M wireless power private network; and the distribution transformer monitoring terminal uploads monitoring data to a remote system master station through the TD-LTE230M wireless power private network. According to the system, the wireless electric power private network independently bears electric power services, physical isolation and reliable communication of the services can be achieved, the risk that information is stolen when a GPRS public network is adopted for transmitting electric power information can be eliminated, the construction period is short, and the system can serve as a main mode of medium and long distance electric power terminal communication.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a distribution transformer monitoring system based on a 230M-LTE network. Background technique [0002] Distribution transformers are power equipment that directly distribute electric energy to low-voltage users, and their operating data are an important part of the basic data of the entire distribution network. With the improvement of living standards of urban and rural residents, the proportion of residents' load demand in the total load is increasing, and the reliability of power supply is also getting higher and higher. For power supply companies, equipment security monitoring is a key concern. Since transformers are surrounded by high-voltage dangerous areas, transformers are generally installed in some remote areas far from living communities, which makes it more difficult for staff to know the working status of transformers and troubleshoot problems in a timely manner. In ...
