Explosion-proof shell for cable

Abstract

The invention discloses an explosion-proof shell for a cable. The explosion-proof shell comprises an outer shell, an explosion-proof cavity formed in the outer shell and a cable connector, and an explosion vibration sensor, an explosion pressure sensor, an aerosol fire extinguisher and a temperature sensor are arranged on the inner wall of the outer shell. The explosion-proof shell is reasonable in structural design and convenient to disassemble and assemble, has fireproof, flame-retardant, explosion-proof and intelligent acquisition and monitoring functions at the same time, can obtain and monitor the internal state of the explosion-proof shell in real time without manual regular inspection, and realizes the intelligence of the explosion-proof shell. The aerosol fire extinguisher arranged in the outer shell can be triggered to extinguish fire in time when explosion occurs, and damage caused by cable explosion can be reduced from the source. The outer shell and the internal cable connector are respectively provided with an explosion-proof structure to form a double explosion-proof mechanism, so that the whole shell has excellent explosion-proof and fire-proof functions, fire accidents caused by cable faults can be prevented, and the situation that the outer shell is directly punctured and exploded to damage the surrounding environment is avoided.

Description

technical field [0001] The invention relates to the explosion-proof field of cable joints, in particular to an explosion-proof housing for cables. Background technique [0002] Since the power grid needs more power supply links and longer transmission lines, the power cable intermediate joint has become an indispensable part of the urban power grid. After the installation of the high-voltage cable intermediate joint is completed, regular inspections are required during operation, and it will also be affected by environmental moisture intrusion, mechanical stress and other factors, resulting in damage or loss of insulation of the intermediate joint, resulting in breakdown explosion accidents of the cable intermediate joint, and explosion shock waves And solid splashes will cause damage to the surrounding environment, people, power equipment, civil foundations, etc. In view of the above situations, it is necessary to install protective equipment on the cable intermediate join...

AI Technical Summary

Problems solved by technology

[0003] Currently commonly used cable explosion-proof shells have single functions, general explosion-proof effects, and lack of intelligent monitoring functions, resulting in many avoidable accidents. Therefore, failures often occur at critical moments, making cable protection not effectively guaranteed.
