Integrated monitoring system for cable tunnel

1、 Demand analysis

With the development of the power grid, the scale of cables is also increasing. The cable tunnel is under the ground, which is a major difficulty for monitoring, maintenance and repair. Often, losses have occurred when hidden dangers are found, which is difficult to recover, seriously affecting the safe operation of the power grid in China. Although there are various monitoring systems at present, they basically can only complete a single function, lacking necessary contact and effective coordination between each other. The integrated, intelligent and visual cable tunnel integrated monitoring system launched by our company can well solve the above pain points, realize real information sharing, and has the ability of integrated monitoring.

2、 Working principle

The cable tunnel integrated monitoring system is mainly composed of cable tunnel remote monitoring center, local monitoring substation and various subsystems. The subsystems include: lighting monitoring subsystem, ventilation monitoring subsystem, drainage monitoring subsystem, video monitoring subsystem, security monitoring subsystem, sheath current carrying capacity monitoring subsystem, emergency call subsystem, infrared microwave dual detection system, partial discharge monitoring subsystem (optional), insulation dielectric loss monitoring subsystem (optional), optical fiber temperature measurement subsystem (optional), and environmental monitoring subsystem (optional).

3、 Functional characteristics
