Lightning arrester on-line monitoring system and control method thereof

Abstract

The invention discloses a lightning arrester on-line monitoring system and a control method thereof and belongs to the technical field of lightning arrester monitoring. The lightning arrester on-linemonitoring system comprises multiple lightning arrester monitoring devices, an NBIOT (narrow-band Internet of Things) and a monitoring center control system, and the lightning arrester monitoring device is used for monitoring the operating status of the lightning arrester in real time to acquire status data and sending the status data to the NBIOT; the NBIOT is used for identifying and processingthe status data of the lightning arrester and transmitting the status data to the monitoring center control system; the monitoring center control system is used for analyzing and processing the statusdata of the lightning arrester to acquire analysis result data and adjust configuration data. The on-line monitoring system of the lightning arrester is established on the basis of the NBIOT, cost isgreatly lowered due to reuse of existing cellular base stations, large scale power network monitoring is facilitated, and maintenance cost of the system is lowered.

Description

technical field [0001] The invention relates to an online monitoring system and a control method for a lightning arrester, belonging to the technical field of lightning arrester monitoring. Background technique [0002] With the development of society, all aspects of people's social life are increasingly dependent on the power system, so the stability and reliability of the power system is very important for the normal operation of the entire society. At present, there are many factors that affect the power grid, and among all these influences, lightning strikes have the greatest impact on the power grid, and the consequences are the most serious. The system causes immeasurable losses. Therefore, a large number of surge arresters are used in the current power grid to protect the power grid. It has become an important electrical device in the power grid to protect power equipment from overvoltage hazards. The reliability of its operation will directly affect the safety of th...

Problems solved by technology

[0003] At present, the domestic online monitoring platforms for arresters are basically evolved from the traditional live detection. They mostly transmit data through wired methods, which makes the monitoring arresters less in number, high in cost, weak in scalability and flexible. Insufficient and large amount of cable laying; during the implementation process, the work of pulling and wiring in the process of establishing the monitoring system is complicated, the workload is heavy, and the cost is high

In addition, a large amount of interference will be introduced in the long-distance transmission of analog quantities, and it is difficult to troubleshoot problems.
