[0025] As Figures 1-4 shown, the utility model provides a transformer substation battery electrical joint flame-out sheath, including pole post sheath 1, cable sheath 2 and connecting frame 5;

[0026] Cable sheath 2 is arranged on one side of pole post sheath 1 and is communicated with pole post sheath 1, the other side of pole post sheath 1 is fixedly connected with one end of connecting frame 5, and pole post sheath 1 and cable sheath 2 are fixed on the battery through connecting frame 5;

[0027] Among them, the inside of pole post sheath 1 and cable sheath 2 is provided with flame-out layer 3.

[0028] In specific implementation, pole post sheath 1 and cable sheath 2 are arranged at the position of the pole post of the battery correspondingly, are fixed through connecting frame 5, pole post sheath 1 can be buckled on the pole post of the battery, so that the pole post of the battery is in the space covered by flame-out layer 3, when the pole post is on fire, the flame-out layer 3 in the inside of pole post sheath 1 and cable sheath 2 will melt and release the fire extinguishing agent in the inside to extinguish the flame, so as to suppress the flame of the pole post and reduce the large-area fire caused by the flame-induced cable spread.

[0029] In some embodiments, the inside of flame-out layer 3 is provided with a plurality of flame-out microcapsules, and the inside of the flame-out microcapsules is provided with perfluorohexanone fire extinguishing agent.

[0030] In specific implementation, the perfluorohexanone extinguishing agent contacts the flame and evaporates rapidly and absorbs a large amount of heat, and changes from a liquid state to a gaseous state, and the heat absorbed in the process causes the temperature around the fire source to decrease; and the vaporization coverage area can isolate oxygen and reduce the content of combustion-supporting agents to below the combustion level, thereby achieving fire extinguishing; when the pole is on fire, the flame-extinguishing layer 3 inside the pole sheath 1 and the cable sheath 2 melts and releases the perfluorohexanone extinguishing agent inside to extinguish the flame, thereby suppressing the flame of the pole.

[0031] In some embodiments, the cable sheath 2 and the flame-extinguishing layer 3 are both flexible, and the wall thickness of the flame-extinguishing layer 3 is 0.3-0.5 cm.

[0032] In specific implementation, the cable sheath 2 is made of rubber, and the wall thickness of the flame-extinguishing layer 3 is 0.3-0.5 cm and will melt after 300°C; after the pole of the battery produces a flame, the flame-extinguishing layer 3 will melt, and the flame-extinguishing layer 3 will release the flame-extinguishing microcapsules inside after melting, and the flame-extinguishing microcapsules will also melt and release the perfluorohexanone extinguishing agent inside after being released to extinguish the flame above 300°C.

[0033] In some embodiments, the outer part of the pole sheath 1 is provided with a temperature-sensing color-changing layer 9.

[0034] In specific implementation, the temperature-sensing color-changing layer 9 is temperature-sensing color-changing ink, and through the arrangement of the temperature-sensing color-changing layer 9, after the pole of the battery produces a flame and generates a temperature, the pole sheath 1 transfers heat, and the outer temperature-sensing color-changing layer 9 will have a significant color change, thereby giving a warning.

[0035] In some embodiments, a threaded hole 8 is formed on the side of the connecting frame 5 away from the pole sheath 1, and a fixing screw 7 is fitted in the threaded hole 8.

[0036] In specific implementation, a straight-angled bending part is arranged on the side of the connecting frame 5 away from the pole sheath 1, and a threaded hole 8 and a fixing screw 7 are formed on the bending part, which are used to fix the connecting frame 5 on the battery.

[0037] In some embodiments, a connecting block 6 is arranged on the side of the connecting frame 5 close to the pole sheath 1.

[0038] In specific implementation, as the fixing screw 7 is screwed in, the connecting block 6 abuts against one side of the battery, and the end of the fixing screw 7 abuts against the other side of the battery, thereby clamping the battery and fixing the pole sheath 1 and the connecting frame 5.

[0039] In some embodiments, a mounting groove 4 is formed in the side wall of the cable sheath 2.

[0040] In the embodiment, the installation groove 4 is communicated with the inside of the pole sheath 1, the cable sheath is made of rubber, and the installation groove 4 in the inside of the cable sheath 2 can be used to open when the cable is sleeved, and the cable sheath 2 can be reset after the cable is sleeved.
