the method comprises the following steps: as shown in fig. 1 and 5, in a normal operation state of the box body 1, the water pump 15 works to deliver water liquid inside the water tank 12 to the cavities inside the heat dissipation plates 7 through the water delivery pipe 14, so that the water liquid takes away heat absorbed by the heat dissipation plates 7 and enters the water tank 12 through the return pipe 20, and thus, the water circulation is used to cool the interior of the box body 1 so as to keep each electrical cabinet inside the box body 1 at a safe working environment temperature, and the power supply of the water pump 15 is different from the power supply inside the box body 1, so that the water pump 15 is prevented from working normally due to a fault inside the box body 1, and the heat dissipation plates 7 are in a horizontal state under the action of the coil springs 8 in a normal operation state;
when the electric cabinet in the box 1 has serious faults such as short circuit and the like and generates high-temperature and high-pressure air flow, heat is conducted to the hydrogen in the heat conduction cylinder 29 through the heat conduction cylinder 29, so that the hydrogen expands and pushes the piston plate 30 to move upwards, further the piston plate 30 drives the lifting plate 27 to move upwards through the slide rod 28, the lifting plate 27 moves upwards through the ejector rod 5 to apply upward thrust to the ring plate 2, as shown in fig. 2 and 3, the ring plate 2 applies outward thrust to the radial direction of the slide cylinder 34 to the corresponding pull rod 31 through the connecting rod 4, so that the pull rod 31 pulls the corresponding sector plate 26 to move in the direction away from the center of the slide cylinder 34, so that the pressure relief pipe 24 is opened, at the moment, the high-temperature and high-pressure air flow in the box 1 enters the water tank 12 through the slide cylinder 34 and the pressure relief pipe 24 and is sprayed out from the interior of the water liquid, the water liquid is used for cooling the high-temperature and high-pressure air flow, and automatic pressure relief treatment is carried out on the interior of the box body 1, so that the pressure and the temperature of the interior of the box body 1 are reduced, and the danger of the box body 1 is further reduced;

9. The automatic voltage relief type transformer substation for the intelligent power monitoring system according to claim 8, characterized in that: the outer side wall of the sliding barrel (34) is sleeved with the annular plate (2), the annular plate (2) can slide up and down on the sliding barrel (34), one end, away from the center of the sliding barrel (34), of the sector plate (26) is fixed with a pull rod (31), the upper surface of the annular plate (2) is hinged to one end, away from the sector plate (26), of the pull rod (31) through a corresponding connecting rod (4), and the lower surface of the annular plate (2) is fixedly connected with the lifting plate (27) through a push rod (5).
10. The use method of the automatic voltage-relief type transformer substation for the intelligent power monitoring system according to any one of claims 1 to 9, characterized by comprising the following steps: the method comprises the following steps:
the method comprises the following steps: when serious faults such as short circuit and the like occur in the box body (1) and high-temperature and high-pressure airflow is generated, the temperature and pressure regulating and controlling mechanism drives the opening and closing mechanism to remove the blockage of the pressure relief pipe (24), so that the pressure relief pipe (24) relieves the pressure in the box body (1);
step two: the temperature and pressure regulating mechanism drives the opening and closing mechanism to remove the blockage of the pressure relief pipe (24) and simultaneously drives the heat dissipation mechanism to increase the cooling and pressure relief capacity of the interior of the box body (1), and the side wall strength of the box body (1) is increased;
step three: the heat dissipation mechanism adjusts heat dissipation power according to the pressure of the pressure relief pipe (24).
