Power transmission and transformation line alarming and monitoring terminal

Abstract

A power transmission and transformation line alarming and monitoring terminal comprises a microcontroller, storages, a display device, a button module, expansion ports, a communication module, a line state monitoring circuit and a main power circuit. The storages comprise a work state storage and a remote download storage. The display device, the storages, the button module, the expansion ports, the communication module and the line state monitoring circuit are connected with the microcontroller. The communication module is in communication connection with the outside, the input end of the line state monitoring circuit and the input end of the main power circuit are connected with power lines respectively, and the main power circuit is connected with and provides work power for the communication module, the storages and the microcontroller. The terminal can be used for monitoring all power lines, accurately find out the fault lines and achieve telephone traffic communication and data communication between the site and a control center, and the terminal is further provided with a self-protection monitoring device.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an alarm monitoring terminal for power transmission and transformation lines. Background technique [0002] In the operation of power transmission and transformation lines, power line faults often occur. Most of the current line fault detection equipment adopts analog circuit technology and shell packaging design. Its functions are relatively simple, and the types of fault detection are relatively single. After a failure, the staff needs to patrol the site to find the fault point, which cannot realize remote reporting, nor can it realize the communication between the site and the monitoring center, which has great limitations. Contents of the invention [0003] In order to overcome the shortcomings of the prior art above, the purpose of the present invention is to provide an alarm monitoring terminal for power transmission and transformation lines, which has powerful functions, ...
