Comprehensive monitoring system and method for power cable tunnel

Abstract

An embodiment of the invention discloses a comprehensive monitoring system and method for a power cable tunnel, wherein the system comprises: a cable body information monitoring mechanism and a tunnelenvironment monitoring auxiliary mechanism, wherein the cable body information monitoring mechanism comprises a ring current monitoring subsystem, a local discharge monitoring subsystem, and a fibertemperature measuring subsystem, wherein the tunnel environment monitoring auxiliary mechanism comprises a video monitoring subsystem, a security subsystem, a firefighting subsystem, a fan / water pump / lighting control subsystem, a toxic harmful gas monitoring subsystem, a personnel positioning subsystem, a robot inspection subsystem, a wireless communication subsystem, and a tunnel tamper-proof monitoring subsystem.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a comprehensive monitoring system and method for power cable tunnels. Background technique [0002] With the continuous development of urban construction, people rely more and more on energy in their work and life, so various urban power supply facilities are also developing rapidly. Among them, the transmission cable is the main carrier of electric power transmission. With the development of society, a huge power supply network composed of transmission cables has been formed. Due to the wide distribution of cables and their high importance, how to improve the real-time monitoring of cable body partial discharge, circulating current, and optical fiber temperature measurement to ensure the safety of cable operation is a problem faced by the current power sector. Once the transmission cable fails, it will not only cause a large-scale power outage that affects the normal operat...

Problems solved by technology

At the same time, when a fire occurs, the internal environment of the power transmission tunnel is very bad, which will not only pose a personal safety threat to the emergency repair personnel, but also cause personal safety hazards because the communication of the emergency repair personnel is blocked.

[0004] At the same time, a large number of high-voltage cables, communication optical cables and other assets laid in the power tunnel have become the key theft targets of criminals. Once a cable or optical cable is stolen or a line failure occurs, it will have a great negative impact on industrial production and residents’ lives.
