The cable joint belongs to the weakest place in the circuit, according to incomplete statistics, 71% cable explosion accidents all happen to the joint in the country. At present, most 10kV cables are placed in the same groove and are adjacent to each other, the problem of multi-loop common path exists, and the phenomena of joint aging and insulation reduction are particularly serious along with the lapse of time in consideration of the factors of uneven joint product quality and installation process. Once the explosion and the burning of the intermediate joint are met, other running lines can be affected, and large-area power failure is caused. For the construction of the reliability of the power grid, the safety protection after the fault of the 10kV cable is particularly important.
The existing cable joint explosion-proof device is used for solving the problem of being used by different cable joint manufacturers, has larger appearance volume and large installation difficulty, and often conflicts with an on-site cable duct to cause the device cannot be used. And the joint explosion-proof device is made of rigid materials with high strength (such as metal materials like stainless steel and the like), has poor fireproof effect, can not effectively prevent the spread of fire after the fire occurs, and can not play a given effect. Meanwhile, the end part of the metal type explosion-proof device needs to be shrunk to match the cable connector, so that the problem of unbalanced internal pressure exists in the end part. When the cable joint explodes, the huge energy of electric arc strikes the inner wall of the explosion-proof device, the impact force distribution generated inside the explosion-proof device generates distortion at the end part, and the impact stress born by certain points of the end part is far larger than that of other parts, so that the end part is more easily cracked. And because the box body is made of metal materials, fragments generated by explosion are easy to cause the safety of surrounding cables, equipment and even personnel.
To this end, the person skilled in the art has made a series of attempts:

for another example, chinese utility model patent document with publication number CN209088511U discloses a flexible explosion-proof sleeve for a cable intermediate joint, which comprises an explosion-proof sleeve main body; the explosion-proof sleeve main body is formed by wrapping a flexible sheet structure for one circle around a cable intermediate joint, two contacted edge parts of the explosion-proof sleeve main body after the explosion-proof sleeve main body is wrapped for one circle around the cable intermediate joint are fixed through locking pieces, and the two contacted edge parts of the explosion-proof sleeve main body are fixed through nylon screws and then sealed through sealing glue; the two ends of the explosion-proof sleeve main body are provided with pressure release valves, and the two ends of the explosion-proof sleeve main body are sealed with the cable through sealing adhesive tapes. The explosion-proof sleeve is small in size and can be installed in various cable channel environments, the application range of the cable explosion-proof sleeve is enlarged, and the coverage rate of the middle head explosion-proof device is increased; in addition, the pressure relief valves are arranged on the two sides of the protective sleeve, so that the pressure can be safely relieved when the internal pressure of the joint reaches a threshold value;
for another example, chinese utility model patent document with publication number CN208112197U discloses a high-voltage cable joint wrapped flexible fire-proof and explosion-proof blanket, which is composed of three layers of flexible materials, namely, a kevlar aramid fiber fire-proof and explosion-proof blanket, a wound aramid fiber cloth and an oxford cloth, which are sequentially arranged; a plurality of buckle type burr belts are sewn on the outer side of the oxford fabric, and the rough surface and the stabbed surface of the buckle type burr belts are respectively sewn at two end parts of the oxford fabric; the Kevlar aramid fiber wire fireproof and explosion-proof blanket is formed by longitudinally weaving two Kevlar aramid fiber wire blankets with the width of 1.6 meters and 10 layers of longitudinally woven Kevlar aramid fiber wires into a Kevlar aramid fiber wire fireproof and explosion-proof blanket with the width of 3.1 meters; after the high-voltage cable joint is wrapped by the high-voltage cable joint wrapping type flexible fireproof explosion-proof blanket, the high-voltage cable joint is tightly tightened and tied by the aid of the hasp type burr belts, and the high-voltage cable joint wrapping type flexible fireproof explosion-proof blanket is convenient to use and install and can be repeatedly assembled, disassembled and used.
Above-mentioned cable joint explosion-proof mechanism has solved the potential safety hazard problem of the explosion-proof box of metal material through the explosion-proof blanket (an explosion-proof surface fabric) that adopts flexible material, but the structure is still comparatively complicated to produce the atress inequality easily when receiving the impact force of explosion, the explosion in the twinkling of an eye produces the circumstances such as too big impact force is difficult to release buffering to explosion-proof blanket, the security performance needs further promotion.
