Problems solved by technology

[0005] The present invention aims to at least solve the problem that the cable joints in the prior art are easy to cause fires and need to cut off the fire source at the source. The existing fire-fighting devices are bulky, waste resources, and are not suitable for narrow cable channels. Each cable joint fire-fighting device is separate One of the technical problems that cannot be managed centrally

Abstract

The invention provides a cable joint fire monitoring and automatic fire extinguishing system which comprises a wrapping shell wrapping a cable joint in a sealed mode and a fire extinguishing device, the fire extinguishing device is communicated with the wrapping shell through a fire extinguishing pipeline, a detection structure used for sensing a fire is arranged in the wrapping shell, and the detection structure is in signal connection with the fire extinguishing device. The fire extinguishing device collects induction signals of the detection structure and transmits the induction signals to the control unit and the monitoring terminal. The cable fire is extinguished from the source, real-time monitoring is achieved, fire extinguishing is timely, the occupied space is small, fire extinguishing is conducted on multiple cable joints through the same fire extinguishing device according to needs, the fire can be predicted in advance through background monitoring, overhauling treatment is conducted in advance, fire is avoided, and safe and reliable operation of an electric power system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power equipment fire protection engineering, in particular to a cable joint fire monitoring and automatic fire extinguishing system. Background technique [0002] With the rapid development of cities, the scope of application of cable tunnels is becoming wider and wider, providing convenience for people's lives, but there are also some problems, among which the fire in cable tunnels caused by explosions at cable joints is the most serious problem. The causes of the fire in the cable tunnel can be divided into two categories: one is the fire caused by the external fire source, because the cable tunnel is closed and isolated from the outside. The other type is the fire accident caused by the failure of the cable body. 70% of the cable accidents are caused by the failure of the cable joint. , the cable insulation or the cable core is damp, etc. During the long-term operation, the temperature of the cable in...
