Description

Technical Field

At the same time, the main transformer is also used to connect power grids of different voltage levels to achieve smooth transition and ensure the stable operation of the power system. Therefore, the fire safety of the main transformer is of vital importance, which involves the stable operation of the entire power system and the safety of personnel. With the continuous development of new energy power generation such as wind power and photovoltaic power generation, the fire safety of the main transformers of wind power, photovoltaic and other substations has also received more and more attention.

In addition, there is also a method of using fire sprinklers to spray water for fire fighting, but because the direction of the sprinkler is fixed, the sprayed water flow is relatively concentrated, and the shape of the main transformer is irregular, so only a local area of ​​the main transformer can be sprayed to extinguish the fire, which has the problems of low fire fighting efficiency and poor effect, and is easy to cause large losses.

[0054] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0055] Figure 1 It is a structural schematic diagram of a fire protection device for a main transformer of a substation according to an embodiment of the utility model. Figure 2 is based on Figure 1 A magnified schematic diagram of area A in the middle. Figure 4 is based on Figure 1 A magnified schematic diagram of the C region. Figure 1 , Figure 2 and Figure 4 In the embodiment, the fire protection device may include a plurality of first fire protection components, a plurality of second fire protection components 20, a water supply component and a temperature monitoring component. Specifically, the first fire protection component may include a first water mist nozzle 6, and the second fire protection component 20 may include a second water mist nozzle 9.

[0056] Multiple groups of first fire-fighting components are arranged on the oil pillow side of the main transformer and are distributed in a linear array. The water outlet of the first fire-fighting components is provided with a first water mist nozzle 6. Multiple groups of second fire-fighting components 20 are respectively arranged on the other sides of the main transformer. The multiple groups of second fire-fighting components 20 located on the same side of the main transformer are distributed in a linear array. The water outlet of the second fire-fighting components 20 is provided with a second water mist nozzle 9. The water supply component is connected to the bottom ends of the multiple groups of first fire-fighting components and the multiple groups of second fire-fighting components 20, and is used to supply water to the multiple groups of first fire-fighting components and the multiple groups of second fire-fighting components 20. The temperature monitoring component is arranged on one of the fire-fighting components and / or the second fire-fighting components 20, and is used to monitor the real-time temperature of the main transformer, and cooperate with the multiple groups of first fire-fighting components and the multiple groups of second fire-fighting components 20 to provide fire protection for the main transformer.

[0057] When a fire occurs in the main transformer, the temperature monitoring component can detect and locate the fire in time. The water supply component starts to supply water to multiple groups of first fire fighting components and multiple groups of second fire fighting components 20. The first fire fighting component can spray water mist on the oil pillow position and the side close to the oil pillow of the main transformer through the first water mist nozzle 6, and the second fire fighting component 20 can spray water mist on the remaining sides of the main transformer through the second water mist nozzle 9. Since multiple groups of first fire fighting components and multiple groups of second fire fighting components 20 can form an encirclement state of the main transformer, fire fighting can be sprayed at any position of the main transformer, thereby ensuring the fire safety of the main transformer.

[0058] Traditional firefighting measures for main transformers include fire extinguishing by covering with sand and water spraying from fire sprinklers. For firefighting by covering with sand, the staff needs to take the initiative to extinguish the fire, which has low fire extinguishing efficiency and poor effect. For water spraying from fire sprinklers, since the direction of the sprinklers is fixed, the sprayed water flow is relatively concentrated, and the shape of the main transformer is irregular, only local areas of the main transformer can be sprayed with water to extinguish the fire, which has the problems of low fire extinguishing efficiency and poor effect, and is easy to cause large losses. In this embodiment of the utility model, the first water mist nozzle 6 and the second water mist nozzle 9 are used in combination with the spraying method to meet the comprehensive firefighting needs of the main transformer. At the same time, since the surface area of ​​the same volume of water when sprayed in the form of water mist droplets is hundreds of times larger than that when sprayed in the form of direct jet flow, when the water mist droplets are sprayed onto the combustion surface, they will absorb a large amount of heat and vaporize rapidly due to the large heat exchange area, so that the surface temperature of the burning material quickly drops below the temperature required for the thermal decomposition of the material, interrupting the thermal decomposition and terminating the combustion, thereby effectively improving the fire extinguishing efficiency and fire extinguishing effect. In addition, the first water mist nozzle 6 can also perform fire spraying on the oil pillow side of the main transformer to adapt to fire fighting use at irregularly shaped parts of the main transformer.

[0059] In this embodiment of the utility model, in order to further improve the accuracy and effect of extinguishing the fire on the main transformer and avoid wasting water resources, an electric water valve can be provided at the connection between each first fire-fighting assembly and each second fire-fighting assembly 20 and the water supply assembly. Specifically, when a fire occurs locally in the main transformer, the electric water valves of multiple groups of first fire-fighting assemblies and / or second fire-fighting assemblies 20 corresponding to the position can be controlled to open for targeted fire extinguishing, thereby improving the accuracy of fire fighting.

[0060] In this embodiment of the present invention, if Figure 2 and Figure 3 As shown, the first fire-fighting assembly may include a first pipeline 3 , a plurality of first water outlet pipes 4 and a second water outlet pipe 5 .

[0061] The bottom end of the first pipe 3 is connected to the water supply assembly, and a plurality of first water outlet pipes 4 are arranged on the side wall of the first pipe 3 and distributed along the height direction of the first pipe 3. A first water mist nozzle 6 is arranged at one end of the first water outlet pipe 4 close to the main transformer. A second water outlet pipe 5 is arranged at the top of the first pipe 3, and a first water mist nozzle 6 is arranged at one end of the second water outlet pipe 5 close to the oil pillow of the main transformer.

[0062] When it is necessary to spray the oil pillow of the main transformer for firefighting, firefighting water is sprayed along the first water mist nozzle 6 of the second water outlet pipe 5 to carry out firefighting treatment on the oil pillow of the main transformer. Since the height of the oil pillow of the main transformer is generally located obliquely above its body, the height of the second water outlet pipe 5 should correspond to the height of the oil pillow. In addition, the multiple first water outlet pipes 4 are distributed along the height direction of the first pipe 3, so that the oil pillow side of the main transformer body can be sprayed for firefighting. Therefore, the multiple first water outlet pipes 4 and the second water outlet pipes 5 can cooperate to provide comprehensive fire protection for the oil pillow and the oil pillow side of the main transformer.

[0063] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, in order to ensure the stability and continuity of the first water outlet pipe 4 and the second water outlet pipe 5 during fire sprinkler operation, the diameters of the first water outlet pipe 4 and the second water outlet pipe 5 are smaller than the diameter of the first pipeline 3 .

[0064] In this embodiment of the utility model, as Figure 2 As shown, the shape of the second water outlet pipe 5 may include an L shape. Specifically, in order to ensure the stability of the second water outlet pipe 5, the second water outlet pipe 5 may include a support rod 10. One end of the support rod 10 is connected to the horizontal section of the second water outlet pipe 5, and the other end is connected to the top of the first pipe 3.

[0065] In this embodiment of the present invention, if Figure 1 As shown, considering the spraying range of the first water mist nozzle 6 and the size of the main transformer, the number of the first water outlet pipes 4 can include three.

[0066] In this embodiment of the utility model, considering the influence of the distance between the first water mist nozzle 6 and the side wall of the main transformer on the spraying range, the water outlet of the first water mist nozzle 6 located at the top is inclined downward by 30°, that is, the water outlet of the first water mist nozzle 6 corresponding to the second water outlet pipe 5 is inclined downward by 30°. At the same time, the water outlets of the two first water mist nozzles 6 located in the middle are inclined downward by 15°, and the water outlet of the first water mist nozzle 6 located at the bottom is inclined upward by 45°. Specifically, the first water mist nozzles 6 located at the top and the bottom can also perform fire fighting on the local areas of the top and bottom of the main transformer.

[0067] In this embodiment of the present invention, if Figure 4 As shown, the second fire-fighting assembly 20 may include a second pipeline 7 and a plurality of third water outlet pipes 8 .

[0068] The bottom end of the second pipe 7 is connected to the water supply assembly, and a plurality of third water outlet pipes 8 are arranged on the side wall of the second pipe 7 and distributed along the height direction of the second pipe 7. A second water mist nozzle 9 is arranged at one end of the third water outlet pipe 8 close to the main transformer.

[0069] When it is necessary to spray the remaining side walls of the main transformer for fire protection, fire water is sprayed out along the second water mist nozzles 9 of the plurality of third water outlet pipes 8 to provide comprehensive fire protection for the remaining sides of the main transformer.

[0070] In this embodiment of the present invention, if Figure 4 As shown, in order to ensure the stability and continuity of the third water outlet pipe 8 during fire sprinkler operation, the diameter of the third water outlet pipe 8 is smaller than the diameter of the second pipe 7 .

[0071] In this embodiment of the present invention, if Figure 1 As shown, considering the spraying range of the second water mist nozzle 9 and the size of the main transformer, the number of the third water outlet pipes 8 can include three.

[0072] In this embodiment of the utility model, considering the influence of the distance between the second water mist nozzle 9 and the side wall of the main transformer on the spraying range, the water outlets of the two second water mist nozzles 9 located at the top are inclined downward by 15°, and the water outlet of the second water mist nozzle 9 located at the bottom is inclined upward by 45°. Specifically, the second water mist nozzles 9 located at the top and the bottom can also perform fire fighting on the local areas of the top and bottom of the main transformer.

[0073] In this embodiment of the present invention, if Figure 1 As shown, the water supply assembly may include a plurality of third pipes 1, a fourth pipe 2, a water pump and a fire water tank.

[0074] Multiple third pipes 1 are connected in sequence to form a ring to enclose one end of the fourth pipe 2 outside the bottom end of the main transformer. One end of the water pump is connected to one of the third pipes 1, one end of the water pump is connected to the other end of the fourth pipe 2, and the other end of the water pump is connected to the fire water tank through the fifth pipe.

[0075] When it is necessary to supply water to the plurality of third pipes 1, the water pump is started to pump water from the fire water tank. Specifically, in order to improve the stability and reliability of the plurality of third pipes 1, cement is poured at the connection between the third pipe 1 and the first pipe 3 or the second pipe 7. This method can fix the third pipe 1 on the one hand, and protect the bottom ends of the first pipe 3 and the second pipe 7 on the other hand, thereby improving the stability of the first pipe 3 and the second pipe 7.

[0076] In this embodiment of the present invention, the actual connection structure of the first fire fighting component, the second fire fighting component 20 and the third pipeline can be as follows: Figure 8 shown.

[0077] In this embodiment of the utility model, the temperature monitoring component may include an infrared thermal imager 15. Specifically, when a fire occurs in the main transformer, the infrared thermal imager 15 can identify the fire. Specifically, in order to be able to conduct comprehensive fire monitoring of the main transformer, an infrared thermal imager 15 can be added near each water mist nozzle to monitor the temperature of the main transformer in real time. Specifically, when the temperature suddenly increases, the feedback circuit will transmit this signal to the background of the central control room and alarm. After the operating personnel check, if the temperature is indeed abnormal, they manually click the spray button, and the first water mist nozzle 6 and / or the second water mist nozzle 9 are turned on to spray and cool down. In addition, if the temperature is too high, automatic spraying can also be triggered to prevent further expansion of the fire.

[0078] In this embodiment of the present invention, in order to reduce the number of infrared thermal imagers 15 used and the installation cost, the temperature monitoring component may also include: Figure 5 and Figure 6 Specifically, in Figure 5 and Figure 6 In the embodiment, the temperature monitoring component may include a fixing plate 14, a driving box 13, an infrared thermal imager 15 and a driving component.

[0079] The fixing plate 14 is disposed on one of the first fire fighting components and / or the second fire fighting component 20, that is, on the first pipe 3 and the second pipe 7, and the driving box 13 is disposed on the fixing plate 14. The infrared thermal imager 15 is disposed on the top of the driving box 13, and the driving component is disposed inside the driving box 13, and is used to drive the infrared thermal imager 15 to reciprocate to adjust the monitoring area of ​​the infrared thermal imager 15 on the main transformer.

[0080] When the fire condition of the main transformer needs to be monitored, the driving component is started, and the driving component drives the infrared thermal imager 15 to reciprocate. The infrared thermal imager 15 can effectively expand the monitoring range when reciprocating, and effectively reduce the number of infrared thermal imagers 15 and the installation cost while ensuring the monitoring range of the main transformer.

[0081] In this embodiment of the present invention, if Figure 5 As shown, the fixing method for the fixing plate 14 and the first fire-fighting component or the second fire-fighting component 20 may include two clamps being fixedly sleeved on the first pipe 3 or the second pipe 7 by means of bolts.

[0082] In this embodiment of the present invention, if Figure 5 and Figure 6As shown, the temperature monitoring assembly may further include a monitoring box 11. Specifically, one side of the monitoring box 11 is open, and the infrared thermal imager 15 is arranged inside the monitoring box 11. Furthermore, a limit baffle is arranged at the opening of the monitoring box 11 for limiting and fixing the infrared thermal imager.

[0083] In this embodiment of the present invention, if Figure 6 and Figure 7 As shown, the driving assembly may include two incomplete gears 19, a gear 18, a rotating shaft 17 and two driving motors 16. Specifically, the driving motor 16 may also include a driving motor and the like.

[0084] The bottom end of the rotating shaft 17 is rotatably connected to the inner bottom of the driving box 13, and the top of the rotating shaft 17 movably passes through the driving box 13 and is fixedly connected to the bottom of the monitoring box 11. The gear 18 is arranged inside the driving box 13 and is fixedly sleeved on the outside of the rotating shaft 17. Two incomplete gears 19 are symmetrically arranged on both sides of the gear 18 and can be meshed and connected with the gears 18 in sequence. Two driving motors 16 are arranged inside the driving box 13, and the output ends of the driving motors 16 are connected to the corresponding incomplete gears 19.

[0085] When the infrared thermal imager 15 needs to be driven to rotate back and forth, the two driving motors 16 are started to drive the two incomplete gears 19 to rotate synchronously. The two incomplete gears 19 mesh with the gear 18 in sequence and rotate in opposite directions, thereby driving the gear 18 to rotate back and forth.

[0086] In this embodiment of the utility model, in order to further ensure the rotation stability of the monitoring box 11, an annular groove 12 is opened on the top of the driving box 13, and a sliding column is provided at the bottom of the monitoring box 11. The sliding column extends into the annular groove 12 and slides in cooperation with the annular groove 12.

[0087] In this embodiment of the present invention, the location and number of the infrared thermal imagers 15 can be set according to actual needs and their monitoring range.

[0088] In this embodiment of the utility model, the cables of the signal circuit and control circuit of the fire protection device can be selected with metal shielding type cables to suppress electromagnetic interference. In addition, the substation generally designs a copper busbar mesh laid along the trench as an anti-interference measure for the secondary system. The cables of the fire protection device should be laid along the trench with the copper busbar mesh, and attention should be paid to increasing the distance between the high-voltage power distribution device and reducing the parallel length between the two.

[0089] On the other hand, the utility model also provides a substation main transformer. Specifically, the substation main transformer may include a main transformer body and the above fire protection device. Specifically, the fire protection device is arranged outside the main transformer body.

[0090] Through the above technical scheme, the substation main transformer and its fire protection device provided by the utility model can accurately monitor the fire situation and location of the main transformer through the temperature monitoring component. The water supply component supplies water to multiple groups of first fire fighting components and multiple groups of second fire fighting components 20. The first fire fighting component sprays fire fighting water in the form of water mist droplets through the first water mist nozzle 6 to carry out fire fighting spraying on the oil pillow and the oil pillow side of the main transformer. The second fire fighting component 20 sprays fire fighting water in the form of water mist droplets through the second water mist nozzle 9 to carry out fire fighting spraying on the remaining sides of the main transformer. The first water mist nozzle 6 and the second water mist nozzle 9 are used to spray in coordination, which can effectively expand the surface area of ​​the fire fighting water spray, thereby improving the fire fighting efficiency and fire fighting effect. In addition, the first water mist nozzle 6 can also carry out fire fighting spraying on the oil pillow side of the main transformer to adapt to the fire fighting use at the irregular shape of the main transformer.
