a first opening and closing door 701 is hinged and installed on one side of a shell 1, a second opening and closing door 702 is hinged and installed on the other side of the shell 1, sliding grooves 703 are formed in the middle portions of the sides, close to the first opening and closing door 701 and the second opening and closing door 702, of the first opening and closing door 701, a sliding opening 704 is formed in one side of the sliding groove 703 of the first opening and closing door 701, a limiting plate 705 is slidably installed on the inner side of the sliding groove 703 at the position of the first opening and closing door 701, the length and the width of the limiting plate 705 are respectively equal to those of the sliding grooves 703, so that the first opening and closing door 701 and the second opening and closing door 702 are limited, a plurality of return springs 706 are welded on one side of the limiting plate 705 at equal intervals, a pulling circular plate 707 is welded on one side of the limiting plate 705 close to the sliding opening 704, the pulling circular plate 707 is slidably installed in the middle portion of one side of the first opening and closing door 701 for facilitating the resetting of the limiting plate 705, a starting lock 708 is fixedly installed on one end, far away from the first opening and closing door 701, of the pulling circular plate 707, an electromagnet 709 is embedded in the inner side of the second opening/closing door 702, the input end of the electromagnet 709 is electrically connected with the output end of the start lock 708, and the input end of the start lock 708 is electrically connected with the fire sensor 607.
The working principle and the using process of the invention are as follows: when the power transformation box needs to be moved, the supporting rod 401 at the bottom end of the protective cover 3 is attached to the bearing plate 402 and penetrates through the first threaded hole 403 through the fixing screw rod 404, so that the supporting rod 401 and the bearing plate 402 are fixed, the limiting screw rod 408 is inserted into the second threaded hole 410, so that the mounting plate 407 and the fixing plate 409 are fixed, the distance between the mounting plate 407 and the fixing plate 409 is adjusted according to the required stability, and therefore when the power transformation box is moved, the shaking of the power transformation box is reduced, and components inside the power transformation box are protected;
when smoke is generated in the transformer substation due to short circuit or overhigh temperature, the smoke is detected by the smoke sensor 201, and meanwhile, the smoke sensor 201 starts the first electric valve 206, so that concentrated carbon dioxide gas placed in the storage tank 202 is discharged along the discharge pipe 205 and is discharged from the discharge hopper 207, the temperature of the interior of the transformer substation is reduced, oxygen is isolated, and the fire in the interior of the transformer substation is avoided;
when a fire is started in the transformer box, the fire light sensor 607 catches the fire light, the second electric valve 603 is started, after the second electric valve 603 is started, the oil stored in the transformer flows into the collecting hopper 602 along the discharge pipe 601, and flows into the placing box 605 through the heat dissipation of the fireproof filter screen 604 in the collecting hopper 602, so that the oil in the transformer is rapidly collected, the phenomenon that the oil in the transformer expands and is sprayed out from the position of the liquid level meter due to the fact that the transformer is heated, the oil accelerates the combustion in the transformer box, meanwhile, the detonation condition is avoided, and the flame combustion speed and the combustion condition of the fire of the transformer box are reduced;
during the daily maintenance, the staff opens the lock 708 through the key, and when the lock 708 that starts was opened, electro-magnet 709 cut off the power supply to lose the restriction to restriction board 705, under the effect of reset spring 706, restriction board 705 follows the sliding tray 703 roll-off in the second door 702 that opens and shuts, and finally gets back to the inside sliding tray 703 of first door 701 that opens and shuts, slides to sliding opening 704 top through pulling plectane 707, thereby opens the transformer case, avoids personnel's mistake to touch simultaneously and opens.
When it is necessary to replenish the liquid carbon dioxide in the hydraulic tank 9, the liquid carbon dioxide is supplied into the hydraulic tank 9 through the supply pipe 8 by connecting the pipe of the replenishment tank to the feed pipe 203 and opening the limiting valve 204.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
