Problems solved by technology

However, due to the influence of construction technology, operating environment and other factors, the middle joint of the cable is more prone to failure, and 90% of the cable failures are caused by the failure of the middle joint.
When an explosion occurs when the middle joint of the cable fails, there will be strong heat and impact, which will often burn out adjacent cables or cause safety hazards to the surrounding environment, causing secondary failures and causing greater losses

Abstract

A novel-cable intermediate-joint explosion-proof apparatus is disclosed. By using the provided novel-cable intermediate-joint explosion-proof apparatus, the structure is simple, installation is convenient and safety is increased. The apparatus comprises a protection tube, an explosion-proof tube, a thermal shrinkage sealing cap, one pair of reinforcing assemblies and one pair of thermal shrinkage sheaths. The explosion-proof tube is connected to the protection tube and is arranged in a center of the protection tube. The thermal shrinkage sealing cap sleeves a pipe orifice of the explosion-proof tube. The pair of reinforcing assemblies is symmetrically arranged and is located at two end pipe orifices of the protection tube. The reinforcing assemblies are connected between a cable and the protection tube. The pair of thermal shrinkage sheaths is arranged on two end pipe orifices of the protection tube respectively. The thermal shrinkage sheaths successively sleeve the protection tube, the reinforcing assemblies and the cable. The apparatus is convenient to be processed and cost is low.

Description

technical field [0001] The invention relates to the field of electrical safety, in particular to an explosion-proof device for a cable intermediate joint. Background technique [0002] With the improvement of urban construction and development level, cable lines are more and more used in medium and low voltage power supply networks due to their excellent characteristics of reliable power supply and concealed laying. When the cable has a long power supply distance, cable connectors are often used for line connection. However, due to the influence of construction technology, operating environment and other factors, the intermediate joints of cables are more prone to failures, and 90% of cable failures are caused by intermediate joints. When an explosion occurs when the middle joint of the cable fails, there will be strong heat and impact, which will often burn out adjacent cables or cause safety hazards to the surrounding environment, causing secondary failures and causing gr...
