Problems solved by technology
The existing problem is that the cable joint explosion-proof device of this structure is both big and clumsy, and it is inconvenient to install and replace; more importantly, when the cable joint explodes, the strong impact force at the moment of explosion will often make this type of "blocking device" "The explosion-proof device of the concept explodes together, thus causing greater harm

Embodiment 1
[0038] See Figure 1 to Figure 5 , The cable joint explosion-proof device of this embodiment is mainly composed of a mounting frame 1, an inner protective cover 2, a protective cover installation assembly 3, an intermediate protective cover 4 and an outer protective cover 5.
[0039] see Figure 3 to Figure 5 , The mounting frame 1 is mainly composed of a base plate 11, a supporting fixed foot 12, an inner mounting ring 13, a middle mounting ring 14, an outer mounting ring 15, a first mounting connecting ring 16 and a second mounting connecting ring 17. The mounting frame 1 is provided with 2 with the same structure, and the 2 mounting frames are arranged in about 1 minute.
[0040] see image 3 , the substrate 11 is composed of a first board 11-1 and a second board 11-2, the first board 11-1 and the second board 11-2 have the same structure and are set as mirror images. When installing, the first board 11-1 and the second plate body 11-2 are butted together to form a compo...

The invention provides an explosion-proof device for a cable joint, and the device is designed based on the evacuation idea of the explosion energy. The device comprises installation racks, an internal protection cover, a central protection cover, and an external protection cover. The internal protection cover, the central protection cover and the external protection cover are respectively an elastic structure part which is provided with a through hole and is shaped like a cylinder. Two ends of the internal protection cover and two ends of the central protection cover are installed on the two installation racks, and two ends of the external installation protection cover are fixedly installed on the two installation racks. In use, a protected cable joint is placed in the internal protection cover, and cables connected with two ends of the protected cable joint passes through the center of the two installation racks. In use, the internal, central and external protection covers respectively achieve the buffering, releasing and absorbing of the energy generated by the explosion of the cable joint. Meanwhile, the fragments which may be generated by the stage-by-stage blocking exposition from the inside to the outside can achieve the effective protection against the explosion of the cable joint, reduces the dangers caused by the explosion of the cabinet joint, and guarantees the safety of a power supply line.
Description
technical field [0001] The invention relates to protection facilities for power transmission lines, in particular to an explosion-proof device for cable joints. Background technique [0002] In the power supply system, long-distance power transmission lines need to rely on numerous cable joints to continue and extend the cables. With the development of society, especially the needs of urban construction, more and more transmission lines have been turned into concealed projects. Among the faults in the operation of transmission lines, the faults of cable joints are the most common. During the operation of cable joints, due to long-term high-load operation, aging short circuit and other reasons, sometimes fires and explosions may occur. Once an explosion occurs, the explosion shock wave and debris will seriously threaten the safety of adjacent cables. Lead to the damage of the entire underground cable and cable channel. Therefore, for power transmission lines, especially co...
