Rural-power-grid distribution-equipment remote on-line fault diagnosis system based on cloud server

Abstract

The invention discloses a rural-power-grid distribution-equipment remote on-line fault diagnosis system based on a cloud server. The system comprises a temperature detection circuit and a voltage detection circuit which are connected to rural-power-grid distribution equipment. The temperature detection circuit and the voltage detection circuit are connected to a controller respectively. The controller is communicated with the cloud server. Detected temperature and voltage are uploaded to the cloud server to carry out storage and sharing. The controller is also connected to alarm equipment through a relay protection device. In the cloud server, according to real-time data, analysis and diagnosis are performed. In the invention, a workload of operation-maintenance personnel is decreased. Through installing various kinds of sensors, voltage detection circuits and temperature detection circuits on the rural-power-grid distribution equipment, low voltage distribution equipment running state data is collected and near fault diagnosis and rapid publishing are realized.

Description

technical field [0001] The invention relates to the field of rural power distribution monitoring, in particular to a remote online fault diagnosis system for rural power distribution equipment based on a cloud server. Background technique [0002] In recent years, after a new round of rural grid transformation and new rural construction, rural power supply companies have successively invested in some smart devices. First of all, the seemingly simple data transmission of the power consumption information collection terminal is actually not simple, because it includes components such as the power consumption information collection terminal, operator network, and master station. If it is further refined, each part also involves Different communication units, if any party (or multiple parties) has a problem, it may cause abnormal communication and cause data transmission failure [0003] The second is that the overheating fault of the power cable joint on the distribution trans...

AI Technical Summary

Problems solved by technology

When encountering the above problems, it was exposed that the fault point of the power distribution equipment in the rural power grid was not accurately located and the information was not transmitted in a timely manner, which made the rural power grid inspection personnel busy in the fault repair process, prolonging the power outage time.
