Description

Technical Field

[0001] The present invention relates to the technical field of temperature control in substations, and particularly to a temperature control and adjustment component for a circuit breaker in a substation. Background Art

[0002] A box-type substation, also called a prefabricated substation or prefabricated transformer substation, is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a steel structure box. It is especially suitable for urban network construction and transformation and is a brand-new substation that emerged after the civil substation.

[0003] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can also close, carry, and break the current under abnormal circuit conditions within a specified time. The circuit breaker is installed in the box-type substation and plays an important role in controlling and protecting the circuit breaker.

[0004] For example, SF6 circuit breakers dominate in high-voltage power systems due to their excellent arc extinguishing ability. However, the liquefaction temperature of SF6 gas is relatively high. When the ambient temperature is relatively low in winter, SF6 gas liquefies, and its insulation and arc extinguishing performance drop significantly, which will cause serious accidents, damage power equipment, and disrupt the safe and stable operation of the power grid.

[0005] However, when the ambient temperature rises, the pressure of SF6 gas inside the circuit breaker also changes with the temperature. Especially for circuit breakers in different application scenarios, their rated gas pressures are different. When the SF6 gas pressure is too high or too low, it will affect the circuit breaker. Therefore, in order to ensure the normal operation of the circuit breaker, it is necessary to monitor and adjust the temperature in the box-type substation in real time.

[0006] Most of the existing box-type substations rely on the heat dissipation holes opened on the surface of the box body and dissipate heat through natural ventilation or by setting exhaust fans. However, when the external environment of the box body is also at a relatively high temperature, it is impossible to quickly cool down the temperature inside the substation box, resulting in an unsatisfactory heat dissipation effect. Moreover, most of the heat dissipation holes are always open. When the outside air enters the inside of the box body, dust in the air will also enter the box body and adhere to the internal equipment, affecting the heat dissipation effect of the equipment itself. Even in rainy and snowy weather, splashing water droplets are likely to enter the inside of the substation, easily causing a short-circuit risk to the equipment.

[0007] Moreover, when the external environmental temperature is relatively low, the existing box-type substation cannot directly heat the air inside it. Since the heat dissipation holes are always open, cold outside air will continuously enter the interior of the box-type substation, causing the circuit breakers and other equipment inside the box-type substation to operate in a relatively low ambient temperature. The performance of the circuit breakers and other equipment will be significantly reduced.

[0008] In summary, the present invention provides a temperature control and adjustment component for a substation circuit breaker to solve the above problems. Summary of the Invention

[0015] Preferably, traction worm wheels are coaxially and fixedly mounted on both of the cloth curtain traction shafts. A traction double-shaft motor is fixedly mounted on the top of the substation housing. Traction worm gears respectively meshing with the two traction worm wheels are fixedly mounted on the rotating shafts on the left and right sides of the traction double-shaft motor.

[0016] Preferably, an extrusion arc plate located inside the cooling wet cloth curtain is fixedly mounted on the bottom surface inside the cooling housing. The arc surface of the extrusion arc plate abuts against the inner side surface of the cooling wet cloth curtain. A wiper plate with an arc-shaped cross-section is rotatably mounted on the bottom surface inside the cooling housing. The free end of the wiper plate is pointed and abuts against the outer side surface of the cooling wet cloth curtain. The wiper plate is connected with a torsion spring. A drainage groove penetrates through the bottom end of each side surface of the cooling housing. A water collecting groove located outside the two cooling housings is formed on the top surface of the substation base. A drainage hole penetrates between each water collecting groove and the side surface of the substation base. A water baffle covering the outside of the drainage groove and the water collecting groove is fixedly mounted on the top surface of the substation base.

[0017] Preferably, the ventilation assembly includes a wind cylinder fixedly mounted on the top of the substation housing and coaxially corresponding to the ventilation hole. An installation plate is fixedly mounted on the inner wall of the wind cylinder. An exhaust fan is mounted at the bottom of the installation plate.

[0018] Preferably, a cylinder cover telescopic rod is mounted on the top of the installation plate.

[0019] Preferably, the sealing assembly includes an air inlet frame installed on the outer side of the cooling housing and corresponding to the air inlet groove.

The plurality of sealing shafts are synchronously rotationally connected through a pulley group.

[0020] The beneficial effects of the present invention are as follows: 1. The ventilation assembly can discharge the air inside the substation housing from the ventilation holes, creating a negative pressure inside the substation housing. As a result, external air enters the inside of the cooling housing through the air inlet groove, passes through the cooling wet curtain to cool the air, and then when the air passes through the moisture-absorbing dry curtain, the moisture carried in the air can be absorbed. Finally, the cooled air enters the inside of the substation housing from the air inlet holes, thereby achieving the cooling and heat dissipation of the temperature inside the substation housing.

[0021] 2. The air inlet groove is arranged at a high position and the air inlet holes are arranged at a low position, which can make the air entering the inside of the cooling housing flow from top to bottom, increasing the contact time with the cooling wet curtain. After the cold air enters the inside of the substation housing from the air inlet holes located at the low position, as the cold air entering therein gradually increases, the hot air gradually rises and is discharged from the ventilation holes, thereby enabling the air inside the substation housing to be efficiently cooled and dissipated.

[0022] 3. When the wet curtain reel winds the cooling wet curtain and makes it move downward, the cooling wet curtain can drive the tip of the wiper blade to swing clockwise by a certain amplitude, squeezing the cooling wet curtain. The cooling liquid inside the cooling wet curtain is squeezed out. Part of the cooling liquid can flow back into the inside of the cooling water tank from the wet curtain groove. The tip of the wiper blade can also scrape off the dust attached to the outer side of the cooling wet curtain and flow into the water collection tank along with another part of the cooling liquid, and finally flow out through the drain hole to the ground or into the sewer.

[0023] 4. When the cylinder cover telescopic rod contracts, the air cylinder cover moves downward to cover the top opening of the air cylinder. At the same time, the air cylinder cover drives two baffle plates to move downward through the shielding connecting rod, thereby exposing the heating air outlet holes on the left and right sides. The exhaust fan is reversely started to blow air into the inside of the substation housing. Since the air cylinder is shielded, the outside air can only enter the inside of the annular housing through several heating air inlet holes and is heated by the electric heating coil, and then enters the air cylinder from the heating air outlet holes and is blown into the inside of the substation housing by the exhaust fan, thereby heating and raising the temperature of the air inside the substation housing to ensure that the circuit breakers and other equipment inside can operate normally in a normal ambient temperature.

[0024] 5. When heating by blowing hot air into the interior of the substation housing, the air inlet frame can be first put into a circulating state, and the air inside the substation housing can then pass through the air inlet holes, the cooling housing, the air inlet grooves in sequence, and be discharged from the air inlet frame to the outside of the substation housing. After the temperature inside the substation housing rises to the specified temperature, multiple sealing plates can be rotated to a sealed state, or only a small gap is left between every two sealing plates, so that the hot air inside the substation housing flows out slowly, ensuring to the greatest extent that the interior of the substation housing can be at the optimal ambient temperature.

[0038] The following will refer to the attached Figures 1 - 12 Describe and explain each embodiment of the present invention in detail.

[0039] A temperature control and adjustment component for a substation circuit breaker, as shown in the attached Figures 1 - 12As shown in the figure, it includes a substation base 1, which can be made of cast concrete. A substation housing 2 is installed on the top of the substation base 1. A temperature detector is installed inside the substation housing 2 to monitor the internal temperature change in real time. Cooling housings 3 are fixedly installed on the left and right sides of the substation housing 2. An air inlet slot 4 penetrates through the top end of the outer side of each cooling housing 3. A number of air inlet holes 5 are opened at the bottom ends of the left and right sides of the substation housing 2. A ventilation hole 6 is opened at the top of the substation housing 2. A ventilation component 7 is installed on the top of the ventilation hole 6. A cooling wet cloth curtain 8 and a moisture-absorbing dry cloth curtain 9 located inside the cooling wet cloth curtain 8 are installed inside the cooling housing 3. The ventilation component 7 can discharge the air inside the substation housing 2 from the ventilation hole 6, generating negative pressure inside the substation housing 2, causing external air to enter the inside of the cooling housing 3 from the air inlet slot 4, passing through the cooling wet cloth curtain 8 to cool the air, and then when the air passes through the moisture-absorbing dry cloth curtain 9, it can absorb the moisture carried in the air. Finally, the cooled air enters the inside of the substation housing 2 from the air inlet holes 5, thus realizing the cooling and heat dissipation of the temperature inside the substation housing 2. The air inlet slot 4 is set at a high position, and the air inlet holes 5 are set at a low position, which can make the air entering the inside of the cooling housing 3 flow from top to bottom, increasing the contact time with the cooling wet cloth curtain 8. After the cold air enters the inside of the substation housing 2 from the air inlet holes 5 located at a low position, as the cold air entering it gradually increases, the hot air gradually rises and is discharged from the ventilation hole 6, thereby enabling the air inside the substation housing 2 to be efficiently cooled and dissipated.

[0040] A traction component 10 for the cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9 is installed inside the substation base 1. A sealing component 11 corresponding to the air inlet slot 4 is installed on the outer side of each cooling housing 3. Through the traction of the traction component 10, the cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9 can be placed inside the cooling housing 3. When it is necessary to heat the air inside the substation housing 2, the traction component 10 can move the cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9 out of the cooling housing 3 and close the sealing component 11. At this time, the ventilation component 7 can heat the outside air and blow it into the inside of the substation housing 2 from the ventilation hole 6, thereby heating the air inside it.

[0041] As shown in the appendix Figure 3 、 Figure 8As shown in the figure, water tank grooves 12 are formed on the top surface of the substation base 1, and are respectively located below the two cooling shells 3. Cooling water tanks 13 are installed inside the water tank grooves 12, and cooling liquid 14 is contained in the cooling water tanks 13. A cooling water circulation machine 15 is installed on the top of the substation base 1. The cooling water circulation machine 15 is communicated with the cooling water tanks 13 through pipelines, and can circulate and cool the cooling liquid 14 inside the cooling water tanks 13. The temperature of the cooling liquid 14 can be adjusted by the staff in advance according to the ambient temperature. A wet cloth curtain reel 16 is rotatably installed between the front and rear inner walls of the cooling water tank 13. A cooling wet cloth curtain 8 is wound around the outer side of the wet cloth curtain reel 16. A wet cloth curtain groove 17 through which the cooling wet cloth curtain 8 can pass is formed in the bottom of the cooling shell 3. When the cooling wet cloth curtain 8 is completely wound around the outer side of the wet cloth curtain reel 16, it can be immersed in the cooling liquid 14. When the cooling wet cloth curtain 8 moves into the cooling shell 3 with the cooling liquid 14 adsorbed inside it, the air entering the cooling shell 3 and passing through the cooling wet cloth curtain 8 can be cooled. At the same time, the cooling wet cloth curtain 8 can also intercept and filter the dust contained in the external air, so that the dust adheres to the outer side surface of the cooling wet cloth curtain 8.

[0042] As shown in the Figure 8 figure, a dry cloth curtain reel 18 is rotatably installed between the front and rear inner walls at the bottom end of the cooling shell 3. A moisture-absorbing dry cloth curtain 9 is wound around the outer side of the dry cloth curtain reel 18. The moisture-absorbing dry cloth curtain 9 can be driven by a cloth curtain traction plate 19 to move into the cooling shell 3.

[0043] Both the wet cloth curtain reel 16 and the dry cloth curtain reel 18 are connected with clockwork springs. When the cloth curtain traction plate 19 receives a traction force, it can pull the cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9 to move upward into the cooling shell 3. The cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9 then pull the wet cloth curtain reel 16 and the dry cloth curtain reel 18 to rotate, and both drive the clockwork springs to store energy. When the cloth curtain traction plate 19 no longer receives a traction force, the wet cloth curtain reel 16 and the dry cloth curtain reel 18 can rotate reversely under the elastic force of the clockwork springs, so as to wind the cooling wet cloth curtain 8 and the moisture-absorbing dry cloth curtain 9, and the two pull the cloth curtain traction plate 19 to move towards the bottom of the cooling shell 3.

[0044] As shown in the Figure 5 and Figure 9 、 Figure 10As shown, the traction assembly 10 includes a curtain traction plate 19 slidably mounted up and down inside each cooling housing 3. The top ends of the cooling wet curtain 8 and the moisture-absorbing dry curtain 9 are both fixedly connected to the bottom surface of the curtain traction plate 19. The curtain traction plate 19 can slide up and down inside the cooling housing 3, thereby pulling the cooling wet curtain 8 and the moisture-absorbing dry curtain 9 to move. A curtain traction shaft 20 with its axis in the front-rear direction is rotatably mounted at the top of each cooling housing 3. Traction rope shafts 21 are coaxially and fixedly mounted at both the front and rear ends of the curtain traction shaft 20. Two traction rope holes 22 penetrate between the top and the inside of the cooling housing 3. A traction rope 23 is wound around the outer side of the traction rope shaft 21, and each traction rope 23 passes through a traction rope hole 22 and is fixedly connected to the top surface of the curtain traction plate 19. When the two curtain traction shafts 20 rotate synchronously, the four traction rope shafts 21 can be driven to rotate synchronously. The traction rope shafts 21 can wind or release the four traction ropes 23, thereby driving the curtain traction plate 19 to slide up and down inside the cooling housing 3.

[0045] As shown in the appendix Figure 5 、 Figure 9 、 Figure 10 As shown, traction worm wheels 24 are coaxially and fixedly mounted on both of the curtain traction shafts 20. A traction double-shaft motor 25 is fixedly mounted on the top of the substation housing 2. The traction double-shaft motor 25 is connected to a power supply and a controller and can be remotely controlled. Traction worm shafts 26 meshing with the two traction worm wheels 24 are fixedly mounted on the rotating shafts on the left and right sides of the traction double-shaft motor 25. When the traction double-shaft motor 25 is started, the two traction worm shafts 26 can be driven to rotate synchronously, and the two traction worm shafts 26 drive the two traction worm wheels 24 and the curtain traction shafts 20 to rotate synchronously, thereby realizing the synchronous winding or release of the four traction ropes 23.

[0046] As shown in the appendix Figure 8 As shown, an extrusion arc plate 27 located inside the cooling wet curtain 8 is fixedly mounted on the bottom surface inside the cooling housing 3. The arc surface of the extrusion arc plate 27 abuts against the inner side surface of the cooling wet curtain 8. A wiper plate 28 with an arc-shaped cross-section is rotatably mounted on the bottom surface inside the cooling housing 3. The free end of the wiper plate 28 is pointed and abuts against the outer side surface of the cooling wet curtain 8 (refer to the shape of the wiper plate 28 in Figure 8 ). The wiper plate 28 is connected with a torsion spring. A drainage groove 29 penetrates through the bottom end of each side of the cooling housing 3. A water collecting groove 30 located outside the two cooling housings 3 is formed on the top surface of the substation base 1. A drainage hole 31 penetrates between each water collecting groove 30 and the side surface of the substation base 1. A water blocking plate 32 covering the outside of the drainage groove 29 and the water collecting groove 30 is fixedly mounted on the top surface of the substation base 1. The water blocking plate 32 can block the drainage groove 29 and the water collecting groove 30; When the cloth curtain traction plate 19 pulls the cooling wet cloth curtain 8 upward, the cooling wet cloth curtain 8 abuts against the outer arc surface of the wiper plate 28. During the upward movement, the wiper plate 28 will not squeeze out the cooling liquid 14 inside the cooling wet cloth curtain 8. At this time, the wiper plate 28 only fits against the outer side surface of the cooling wet cloth curtain 8 under the elastic force of the torsion spring. However, when the wet cloth curtain reel 16 winds the cooling wet cloth curtain 8 and makes it move downward, the cooling wet cloth curtain 8 can drive the tip of the wiper plate 28 to swing clockwise by a certain amplitude, thereby squeezing the cooling wet cloth curtain 8. The inner side surface of the cooling wet cloth curtain 8 abuts against the extrusion arc plate 27. Therefore, the cooling liquid 14 inside the cooling wet cloth curtain 8 will be squeezed out. Part of the cooling liquid 14 can flow back into the interior of the cooling water tank 13 from the wet cloth curtain groove 17, and part of it flows out along the inner arc surface of the wiper plate 28 and out of the drainage groove 29 into the interior of the water collecting tank 30. At the same time, the tip of the wiper plate 28 can also scrape off the dust attached to the outer side surface of the cooling wet cloth curtain 8, and flow into the interior of the water collecting tank 30 along with the cooling liquid 14, and finally flow out to the ground or into the sewer through the drainage hole 31.

[0047] As shown in the attached Figure 6 、 Figure 7 、 Figure 12 figures, the ventilation component 7 includes a wind cylinder 33 fixedly installed on the top of the substation housing 2 and coaxially corresponding to the ventilation hole 6. An installation plate 34 is fixedly installed on the inner wall of the wind cylinder 33. A exhaust fan 35 is installed at the bottom of the installation plate 34. The drive of the exhaust fan 35 is a motor that can start in both forward and reverse directions. The exhaust fan 35 can discharge the air inside the substation housing 2, and when it rotates in reverse, it can blow the outside air into the substation housing 2. A bottom groove 36 is formed on the top surface of the substation base 1. A grille plate 37 is installed inside the bottom groove 36. A circuit breaker is installed on the top of the grille plate 37. A disturbance fan 38 is rotatably installed inside the bottom groove 36. The disturbance fan 38 is connected to a power supply and a controller. When the air is cooled and enters the interior of the substation housing 2 through the air inlet hole 5, the disturbance fan 38 can stir the cooled air to quickly spread it inside the substation housing 2 for rapid cooling.

[0048] As shown in the attached Figure 6 、 Figure 7 、 Figure 12As shown, a cylinder cover telescopic rod 39 is installed on the top of the mounting plate 34. An electric push rod can be selected. The telescopic end of the cylinder cover telescopic rod 39 is fixedly installed with a wind cylinder cover 40. The bottom of the wind cylinder cover 40 is conical. A ring-shaped housing 41 is coaxially and fixedly installed on the outer side of the wind cylinder 33. An electric heating coil 42 is installed inside the ring-shaped housing 41. The heating temperature of the electric heating coil 42 can be remotely controlled. A number of heating air inlet holes 43 penetrate through the left and right sides of the outer side surface of the ring-shaped housing 41. A number of heating air outlet holes 44 penetrate through the left and right sides of the outer side surface of the wind cylinder 33. Two position-symmetrical baffles 45 are coaxially and slidably installed on the inner wall of the wind cylinder 33. The top of each baffle 45 is fixedly installed with a shielding connecting rod 46. Each shielding connecting rod 46 is fixedly connected to the bottom of the wind cylinder cover 40; As shown in the Figure 6 accompanying drawings, when the telescopic end of the cylinder cover telescopic rod 39 is in the extended state, the wind cylinder cover 40 is separated from the wind cylinder 33. At this time, the heating air outlet holes 44 on both the left and right sides are blocked by the two baffles 45. When the air inside the substation housing 2 can be discharged from the wind cylinder 33, the conical surface of the wind cylinder cover 40 can guide the air; As shown in the Figure 12 accompanying drawings, when the telescopic rod of the cylinder cover telescopic rod 39 contracts, the wind cylinder cover 40 moves downward to cover the top opening of the wind cylinder 33. At the same time, the wind cylinder cover 40 drives the two baffles 45 to move downward through the shielding connecting rods 46, thereby exposing the heating air outlet holes 44 on both the left and right sides. Then, the electric heating coil 42 can be started, and the exhaust fan 35 can be started in reverse to blow air into the substation housing 2. At this time, since the wind cylinder 33 is shielded, the outside air can only enter the inside of the ring-shaped housing 41 from a number of heating air inlet holes 43, and thus be heated by the electric heating coil 42, and then enter the wind cylinder 33 from the heating air outlet holes 44 and be blown into the inside of the substation housing 2 by the exhaust fan 35, thereby heating and raising the temperature of the air inside the substation housing 2 to ensure that the circuit breakers and other equipment inside can operate normally in a normal ambient temperature; A top plate 47 is installed on the top of the substation housing 2. The top plate 47 can protect the top of the wind cylinder 33.

[0049] As shown in the Figure 1 accompanying drawings Figure 9As shown, the sealing assembly 11 includes an air inlet frame 48 installed on the outer side surface of the cooling housing 3 and corresponding to the air inlet groove 4. A plurality of sealing shafts 49 are rotatably installed between the front and rear side surfaces of the air inlet frame 48 and are equally distributed vertically at equal intervals. A sealing plate 50 is fixedly installed on the outer side of each sealing shaft 49. Inclined surfaces 51 capable of sealingly abutting against adjacent sealing plates 50 are provided at both the upper and lower ends of each sealing plate 50. The plurality of sealing shafts 49 are synchronously rotationally connected through a pulley group 52, so that the plurality of sealing shafts 49 rotate synchronously. When the plurality of sealing plates 50 rotate to the vertical state, sealing is achieved between the plurality of sealing plates 50, and thus the air inlet frame 48 is in a sealed state; When hot air is blown into the interior of the substation housing 2 for heating, the air inlet frame 48 can be first placed in a flowing state. The air inside the substation housing 2 can then sequentially pass through the air inlet holes 5, the cooling housing 3, the air inlet groove 4, and be discharged from the air inlet frame 48 to the outside of the substation housing 2. When the temperature inside the substation housing 2 rises to the specified temperature, the plurality of sealing plates 50 can be rotated to the sealed state, or only a small gap is left between every two sealing plates 50, so that the hot air inside the substation housing 2 flows out more slowly, ensuring to the greatest extent that the interior of the substation housing 2 can be in the optimal ambient temperature.
