[0060] This embodiment is implemented as follows:

[0061] When the present application is in use, the airbag bag 300 is first placed in the positioning sleeve 200, and then the positioning sleeve 200 is put on the outer wall of the capacitor body 100, so that the airbag bag 300 can be located between the capacitor body 100 and the positioning sleeve 200. By means of the first release component 400, the second release component 500, the third release component 600 or the fourth release component 700 provided on the positioning sleeve 200, the airbag bag 300 can be directly or indirectly ruptured, so that the dry powder fire extinguishing material filled in the airbag bag 300 can rush out along with the air in the airbag bag 300, thereby playing a role in extinguishing the fire.

[0062] In the present application, the airbag bag 300 can be limited in position by the positioning ring 310 in the positioning sleeve 200 .

[0063] See also Figure 1 , 2 , 3, 4, 5, 8, 10, 12, the two ports of the positioning sleeve 200 are respectively provided with an internal threaded sleeve 210 and a clamping sleeve 220, an external threaded sleeve 211 is provided at a position corresponding to the internal threaded sleeve 210 on the outer wall of the capacitor body 100, and a limiting sleeve 221 is provided at a position corresponding to the clamping sleeve 220, and the internal threaded sleeve 210 is threadedly connected with the external threaded sleeve 211.

[0064] The clamping sleeve 220 disposed on the positioning sleeve 200 can pass through the external threaded sleeve 211 and be sleeved on the limiting sleeve 221 , and the internal threaded sleeve 210 can be connected to the external threaded sleeve 211 by rotating the clamping sleeve 220 , so that the position of the positioning sleeve 200 is fixed.

[0065] See also Figure 3 , 4 Isolation nets 320 are respectively provided on the outer wall of the capacitor body 100 at positions corresponding to the airbag bags 300 .

[0066] The isolation net 320 can be provided to provide a gap between the airbag bag 300 and the outer wall of the capacitor body 100 , thereby reducing the influence of the heat energy of the capacitor body 100 on the airbag bag 300 .

[0067] See also Figure 1 , 3 , 5, 8, 10, 12, a first net sleeve 230 is embedded in the position of the positioning sleeve 200 corresponding to the position between two adjacent airbag bags.

[0068] The first net cover 230 can make the airbag bag 300 more easily burnt by fire and ruptured.

[0069] See also Figure 1 , 2 3. The first release assembly 400 includes

[0070] The first positioning ring 410 and the second positioning ring 420 are respectively fixedly sleeved on the outer wall of the positioning sleeve 200;

[0074] When the fire reaches the deformable plate 430 , the deformable plate 430 will expand and deform due to the heat, so that the deformable plate 430 drives the first needle 440 to move, so that the first needle 440 can move in the first through hole 451 , so that the first needle 440 can pierce the airbag 300 .

[0075] See also Figure 5 , 6 7. The second release assembly 500 includes

[0076] A third net sleeve 560 is embedded in the positioning sleeve 200 at a position corresponding to each airbag bag 300;

The first connecting plate 530 will drive the second needle body 540 to move in the third through hole 561, so that the second needle body 540 will puncture the airbag bag 300 at the corresponding position, allowing the dry powder fire extinguishing material in the airbag bag 300 to pass through the third mesh sleeve 560 for extinguishing the fire.

[0082] See also Figure 8 , 9 The third release assembly 600 includes

[0083] A plurality of extension tubes 301 are respectively disposed on the airbag bag 300 and communicated with the airbag bag 300;

Both ends of the net tube 710 pass through the fifth net sleeve 760 , and the connecting tube 302 passes through the net tube 710 .

[0090] The connecting pipe 302 is provided to connect adjacent airbag bags 300 , so that the connecting pipe 302 extending out of the positioning sleeve 200 can be burned off by the fire, thereby allowing the dry powder fire extinguishing material in the airbag bag 300 to spray out. The network pipe 710 of the present application can locate and protect the position of the connecting pipe 302 .

[0092] In order to make the connecting tube easier to break, when the fire burns the second connecting rope 750, the restoring force of the second spring 740 will drive the second connecting plate 731 to move, so that the second connecting plate 731 drives the blade 730 to move toward the connecting tube 302, so that the blade 730 can cut off the connecting tube 302, so that the dry powder fire extinguishing material in the airbag bag 300 connected to the connecting tube 302 is sprayed out.
