Safe operating and fault remote-positioning system for ring network cabinet

Abstract

The invention relates to a remote automatic monitoring device, especially to a safe operating and fault remote-positioning system for a ring network cabinet. The technical scheme comprises three parts: a monitoring center, transmission networks and on-site equipment. The monitoring center is provided with a data server, a browsing terminal, an operation terminal, a network short message server and a preposition work station, which are used for receiving the data of each monitoring point, realizing the functions of data storage, analysis, determination and alarming, etc, and reminding relevant work staff of the on-site operation condition in different ways. The system of the invention can timely detect the cases of the ring network cabinet such as the rising of a cable temperature, the alarming of a fault indicator, etc, and when the temperature rises to a certain limit value, the system can immediately give an alarm and prompt users to take measures to prevent accidents, thereby greatly raising the operation security of distribution networks. Besides, when a line has a fault, the system can automatically report fault information, and through the analysis of software, automatically determine a fault position, rapidly search for the fault and timely recover power supply, thereby raising the reliability of power supply.

Description

1. Technical Field: [0001] The invention relates to a remote automatic monitoring device, in particular to a system for safe operation and fault remote positioning of a ring network cabinet. 2. Background technology: [0002] With the advancement of society and the continuous improvement of informatization and automation, people's dependence on the power industry is further deepened, and higher requirements are put forward for the reliability of the power supply system. However, due to the complexity of the power distribution network and the long line distance, line faults are inevitable. After a fault occurs, the ability to quickly restore power supply has become an important concern for the power supply department. [0003] In addition, with the increase in power consumption, many cable joints in the distribution network have overheated due to problems such as long running time and manufacturing technology. For example, the operating environment of ring network cabinets and box ...

AI Technical Summary

Problems solved by technology

[0004] At present, fault indicators are widely used in power distribution lines, but once a line fault occurs, the indicator in the fault area will flip, and line maintenance personnel need to patrol the line to determine the location of the fault, which makes the fault treatment not timely enough
