The main components of the transformer station power cabinet include: Circuit breaker: used to protect the circuit from abnormal current and short circuit and other faults. The circuit breaker is one of the most important components in the power cabinet, responsible for the separation and combination of the circuit to achieve reliable control of the circuit. Isolating switch: used to cut off the power supply and isolate the power supply for the convenience of maintenance and repair of electrical equipment. Isolating switch can also be used as a control circuit or as a circuit breaker for electrical connection.

An empty slot 11 is opened inside the base chassis 2, and two groups of magnet plates 2 12 are fixedly installed in the corresponding empty slots 11 of the base chassis 2. The two groups of magnet plates 2 12 are located directly below the two groups of magnet plates 10, and the magnet plate 2 12 in the base chassis 2 and the magnet plate 10 at the bottom of the transformer station power cabinet 1 are magnetically repelled, and the middle of the corresponding empty slot 11 in the base chassis 2 is slidably connected.

The fluid medium 16 is one of lead particles or sand particles. At the same time, due to the design of the bottom center seat 5 at the bottom end of the base chassis 2 and the U-shaped groove 15 and the fluid medium 16 are provided inside the bottom center seat 5, the center of gravity of the power cabinet 1 of the transformer station as a whole can be lowered. Thereby, the stability is improved. At the same time, based on the principle of communicating vessels and the principle of the tumbler, when the U-shaped tube is filled with liquid and the liquid levels on both sides are level, it indicates that the system is in a balanced state, that is, when the liquid levels of the fluid medium 16 on both sides of the U-shaped groove 15 tend to be horizontal, the balance of the transformer station power cabinet 1 can always be maintained, and when the base chassis 2 is tilted, the transformer station power cabinet 1 can still stand upright, thereby further improving the overall seismic resistance and stability of the power supply device; the power supply device can be widely used in earthquake-prone areas, thereby improving the practicality and applicability of the high-stability power supply device.

[0023] The back and front sides of the transformer station power cabinet 1 are both provided with switch doors 3 , and the transformer station power cabinet 1 can be opened through the switch doors 3 from the front and the back, which is convenient for maintenance of the inside of the transformer station power cabinet 1 .

[0024] The multiple groups of air inlets 17 opened on one side of the power cabinet 1 of the transformer station are distributed in a matrix of two columns and three rows, that is, the multiple groups of air flow channels 9 in the fume hood 8 are also distributed in a matrix corresponding to the multiple groups of air inlets 17, and the air flow channel 9 is composed of a ventilation transverse groove 1 18, a circular through groove 19 and a ventilation transverse groove 2 20 connected in sequence, and the air flow channel 9 is connected to the air inlet 17 through the ventilation transverse groove 18.

[0025] The width and height of the air inlet 17, the ventilation transverse groove 1 18 and the ventilation transverse groove 2 20 are the same and their axes are located on the same horizontal line. The axes of the ventilation transverse groove 1 18 and the ventilation transverse groove 20 and the axis of the circular through groove 19 are not located on the same horizontal line.

[0026] The accelerating ventilation mechanism comprises a central shaft 21, a disc member 22, a baffle member 25 and a servo motor 6. A group of central shafts 21 are rotatably installed in the two corresponding columns of air flow channels 9 in the fume hood 8, and the central shaft 21 passes through the bottom inner wall of each row of circular through grooves 19 from top to bottom in sequence, and the position where the central shaft 21 passes through the bottom inner wall of the circular through grooves 19 is located in the middle of the ventilation transverse groove 18 and the ventilation transverse groove 20, that is, the central shaft 21 and the circular through grooves 19 are eccentrically connected, and a disc member 22 is fixedly sleeved in each group of circular through grooves 19 on the central shaft 21, and an annular groove 23 is opened on the bottom inner wall of the circular through groove 19 corresponding to the outer ring, and three groups of vertical columns 24 are slidably clamped in the annular groove 23, and baffle members 25 are respectively hinged between the three groups of vertical columns 24 and the outer ring side walls of the disc member 22, and two groups of servo motors 6 are fixedly installed on the top of the fume hood 8, and the output shafts of the two groups of servo motors 6 are respectively fixedly connected to the two groups of central shafts 21.

[0027] The length of the baffle member 25 is greater than the opening width of the ventilation transverse groove 18 and the ventilation transverse groove 20, and the end side of the baffle member 25 is in contact with the inner wall of the side of the circular through groove 19. As the disc member 22 rotates, one end side of the baffle member 25 slides in the annular groove 23 through the vertical column 24. Cavities of different sizes are formed between the three groups of baffle members 25 and the outer wall of the disc member 22 and the inner wall of the circular through groove 19, and the volume of the group of cavities close to the ventilation transverse groove 18 is the smallest, and the volume of the group of cavities close to the ventilation transverse groove 20 is the largest.

[0028] Working principle: The transformer station power cabinet 1 generates repulsive force through the magnetic repulsion between the magnet plate 10 on both sides of the bottom and the magnet plate 2 12 and the magnet plate 3 13 on both sides of the base chassis 2, that is, the two sides of the bottom end of the transformer station power cabinet 1 and the two sides of the base chassis 2, so that the transformer station power cabinet 1 stands upright on the base chassis 2. In the event of an earthquake, the base chassis 2 will tilt and shake, that is, at this time, the distance between the two sides of the base chassis 2 and the two sides of the bottom end of the transformer station power cabinet 1 will change, and the distance on one side will increase and the distance on the other side will decrease. The repulsive force between the transformer station power cabinet 1 and the base chassis 2 on the side with the smaller distance will increase, and the repulsive force between the transformer station power cabinet 1 and the base chassis 2 on the side with the larger distance will increase. becomes smaller, at this time, the magnet plate four 14 and in the base chassis 2 will slide toward the side where the spacing becomes larger as the base chassis 2 tilts, thereby increasing the repulsive force between the transformer station power cabinet 1 and the base chassis 2 on the side where the spacing becomes larger, and at the same time, the magnet plate three 13 on the side where the spacing becomes smaller will slide toward the middle of the base chassis 2, thereby reducing the repulsive force between the transformer station power cabinet 1 and the base chassis 2 on the side where the spacing becomes smaller, so that when the base chassis 2 tilts, the repulsive forces on both sides are balanced, thereby ensuring that the transformer station power cabinet 1 stands upright on the base chassis 2, that is, preventing the transformer station power cabinet 1 from tilting, thereby improving the seismic resistance of the power supply device, and will not tilt during an earthquake, thereby ensuring that the internal electrical components will not be damaged, and ensuring high stability of operation; At the same time, due to the design of the bottom center seat 5 at the bottom end of the base chassis 2 and the U-shaped groove 15 opened inside the bottom center seat 5 and filled with fluid medium 16, the center of gravity of the transformer station power cabinet 1 as a whole can be lowered, thereby improving stability. At the same time, based on the principle of the communicating vessel and the principle of the tumbler, when the U-shaped tube is filled with liquid and the liquid levels on both sides are level, it indicates that the system is in a balanced state, that is, when the liquid levels of the fluid medium 16 on both sides of the U-shaped groove 15 tend to be horizontal, the balance of the transformer station power cabinet 1 can always be maintained, and when the base chassis 2 is tilted, the transformer station power cabinet 1 can still stand upright, thereby further improving the overall seismic resistance and stability of the power supply device; the power supply device can be widely used in earthquake-prone areas, thereby improving the practicality and applicability of the high-stability power supply device.

[0029] At the same time, during the operation of the high-stability power supply device, when the internal electrical components are stably increased, the ventilation hood 8 set on one side of the transformer station power cabinet 1 and the accelerating ventilation mechanism in the ventilation hood 8 can accelerate the air circulation inside the transformer station power cabinet 1 for rapid cooling. At this time, the two groups of servo motors 6 can be driven to drive the two groups of central shafts 21 of the ventilation hood 8 to rotate. At this time, the disc members 22 in each group of air flow channels 9 rotate synchronously. When the disc members 22 rotate, the three groups of baffle members 25 on the outside can be driven to rotate, and different sizes of air spaces are formed between the baffle members 25 and the outer wall of the disc member 22 and the inner wall of the circular through groove 19. The volume of the cavity is the smallest among the cavities near the ventilation groove 18, and the volume of the cavity near the ventilation groove 20 is the largest. That is, after the air enters the air flow channel 9 through the ventilation groove 20, it flows as the baffle 25 rotates, and in the process of approaching the ventilation groove 18, the volume of the cavity gradually decreases, so that the air can be compressed, and when the compressed air encounters the ventilation groove 18, it will accelerate through the air inlet 17 to enter the interior of the transformer station power cabinet 1, thereby accelerating the ventilation inside the transformer station power cabinet 1, that is, improving the effect of cooling the electrical components by traditional air cooling.
