Description

Technical Field

[0001] The invention relates to the technical field of oil-immersed transformers, and in particular to an oil-immersed transformer with a disaster prevention function. Background Art

[0002] Oil-immersed power transformers are widely used in power systems and are important equipment for power conversion. The reliability, stability and safety of their operation are crucial. Oil-immersed transformers are important equipment in power systems. They are filled with oil and play the role of insulation, heat dissipation, cooling, arc extinguishing, etc. Failures during normal operation may cause serious fires. Therefore, the improvement of fire protection measures in the transformer area plays a very important role in the normal operation of the substation.

[0003] Oil-immersed transformers contain several tons to hundreds of tons of hydrocarbon insulating mineral oil, with a combustion calorific value of up to 40MJ / kg and an oil fire temperature of over 1400°C, making it extremely difficult to extinguish. Once a fire occurs, it is very likely to cause an explosion, leading to serious economic losses such as burning of important equipment and large-scale power outages, and even personal safety accidents. However, currently, the alarm is used to alert others so that the staff can respond quickly to extinguish the fire, but the oil-immersed transformer itself cannot extinguish the fire, so it cannot effectively reduce the severity of the fire.

[0004] Therefore, it is necessary to design an oil-immersed transformer with disaster prevention function that can realize automatic fire extinguishing and reduce the degree of fire. Summary of the invention

[0005] In order to overcome the current disadvantage that the alarm is used to remind others so that the staff can respond quickly to extinguish the fire, but the oil-immersed transformer itself cannot extinguish the fire, so the degree of the fire cannot be effectively reduced, the technical problem of the present invention is to provide an oil-immersed transformer with disaster prevention function that can realize automatic fire extinguishing and reduce the degree of fire.

The lower side of the third connecting tube close to the guide column is slidably connected to the guide hollow column. The guide hollow column and the threaded column are connected by threads. The second spring is connected between the guide hollow column and the third connecting tube. The upward movement of the guide column will squeeze the guide hollow column to move toward the side close to the rotating plate.

The upper left side of the fixed frame 30 is connected to the storage barrel 60, the upper side of the storage barrel 60 is connected to the third connecting pipe 68, the lower end of the third connecting pipe 68 is connected to the storage barrel 60, and the lower part of the third connecting pipe 68 is rotatably connected to the rotating plate 67. The front and rear parts of the left side of the storage barrel 60 are both connected to the connecting bracket 61, and the connecting bracket 61 is slidably connected to the guide column 62. The upward movement of the movable plate 31 will squeeze the guide column 62 to move upward.

[0038] When the temperature of the transformer 2 rises, the motor 32 can be started, thereby driving the screw rod 33 to rotate, and then the movable plate 31 is driven to move upward through the thread, thereby driving the connecting support frame 1 and the transformer 2 to move upward, so that the transformer 2 can be lifted in the air for explosion, thereby reducing ground damage; at the same time, the booster pump 41 can be started, and then the oil in the transformer 2 is extracted through the first connecting pipe 40, and then discharged into the connecting coil 42 for heat dissipation. The heat dissipation fins 43 can increase the heat dissipation area and accelerate the heat dissipation effect. At the same time, the fan 44 can be started to further accelerate the heat dissipation effect; the fire extinguishing agent contained in the storage barrel 60 will also contact the guide column 62 when the movable plate 31 moves upward, thereby squeezing the guide column 62 to move upward, and the first spring 63 is compressed When the guide column 62 moves upward, it will squeeze the guide hollow column 64 to move toward the side close to the rotating plate 67. When the guide hollow column 64 moves, it will drive the threaded column 66 and the rotating plate 67 to rotate through the thread. When the rotating plate 67 rotates, it will no longer block the third connecting pipe 68. At this time, the fire extinguishing agent contained in the storage barrel 60 will enter the transformer 2 through the third connecting pipe 68, the second one-way valve 69 and the second metal hose 610, thereby extinguishing the fire. At the same time, the guide column 62 continues to move upward, squeezing the button 611 to trigger the alarm 612, thereby realizing an alarm to remind people. In actual use, the transformer 2 can be monitored by temperature sensors, smoke sensors, monitors, etc., and then the motor 32 and the booster pump 41 can be controlled by the controller to operate.

The second connecting pipe 50 is connected between the upper side of the first metal hose 52 and the connecting coil 42, and the second connecting pipe 50 is connected to the intelligent valve 51.

[0040] When the oil in the transformer 2 reaches a certain temperature, the intelligent valve 51 will automatically open, so that the oil in the connecting coil 42 enters the collecting box 54 through the second connecting pipe 50 and the first metal hose 52, thereby discharging the oil in the transformer 2 and reducing the explosion degree of the transformer 2; when the movable plate 31 moves upward, it will drive the second connecting pipe 50 and the intelligent valve 51 to move upward, and the first metal hose 52 will be stretched, thereby not affecting the upward movement of the movable plate 31.

[0041] like Figure 1 and Fig.10As shown, it also includes a knocking mechanism 7, which includes a fixed bracket 70, a rotating blade column 71, a fixed connecting frame 72, a guide knocking column 73, a third spring 74 and a bell block 75.

The left and right parts of the rotating blade column 71 are both connected to the fixed connecting frame 72. The fixed connecting frame 72 is slidably connected with a guide knocking column 73. The third spring 74 is connected between the guide knocking column 73 and the fixed connecting frame 72. The fixed brackets 70 are all connected with bell blocks 75, and the guide knocking column 73 is in contact with and cooperates with adjacent bell blocks 75.

[0042] When wind is needed, the rotating blade column 71 will be blown to rotate, which will then drive the guide knocking column 73 to rotate. The guide knocking column 73 will rotate and come into contact with the bell block 75, thereby knocking the bell block 75 to make a sound, thereby achieving the effect of dispersing birds, thereby preventing birds from staying on the transformer 2 and causing the circuit to be affected and a fire to occur.

[0043] like Figure 1 and Fig.12 As shown, a deceleration mechanism 8 is also included, which includes a base plate 80, a guide block 81 and a fourth spring 82. The left and right parts of the lower side of the fixed frame 30 are connected to the guide blocks 81. The base plate 80 is connected between the guide blocks 81 through a damping sliding type, and four fourth springs 82 are connected between the base plate 80 and the guide blocks 81.

[0044] In case of earthquakes, etc., shock absorption is achieved through the action of the damping and the fourth spring 82, thereby preventing the transformer 2 from being damaged due to vibration, thereby preventing the transformer 2 from being damaged and causing accidents.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the protection scope of the present invention. Although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
