Description

Technical Field

[0001] The present invention relates to the technical field of transformer boxes, in particular to a box-type transformer substation protection structure for outdoor use. Background Art

[0002] A box-type substation is a prefabricated substation that integrates functional modules such as high-voltage switchgear, distribution transformers, and low-voltage distribution devices in a compact box. It has the characteristics of compact structure, easy installation, and small footprint. It is often used in power grid transformation, industrial parks, and construction sites. Among them, in terms of power grid transformation, box-type substations are widely used in rural areas, especially providing great convenience for power grid construction in mountainous rural areas.

[0003] Although box-type substations have many advantages, when they are used in mountainous rural areas, the temperature difference between day and night is large and the humidity is high, which can easily lead to condensation in internal substation equipment and failure of electric heaters, affecting normal operation.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] A box-type substation protection structure for outdoor use, such as Figure 1-Figure 4As shown, it includes: a box-type substation 1, a door 2, a blade 3, a metal pressure rod 4, a magnet 5, a non-magnetic sliding plate 6, a first return spring 601, a nickel-iron sliding plate 7 and a wind regulation unit. The box-type substation 1 is used to install substation equipment. Several doors 2 are installed on the outer wall of the box-type substation 1. Several blades 3 are rotatably connected to the door 2. The center of rotation of the blade 3 is located at the upper end of the blade 3. The upper and lower blades 3 can contact each other during the rotation process to reduce the flow of air between the two blades 3, which is used to block rainwater and ventilate the interior of the box-type substation 1. Several first sliding grooves 201 are mirror-distributed on the door 2. The metal pressure rod 4 corresponds to the blade 3 one by one, and the metal pressure rod 4 is located on the outer side of the corresponding blade 3. The two ends of the metal pressure rod 4 are respectively slidably connected to the corresponding first sliding groove 201. The metal pressure rod 4 can press down the corresponding blade 3 to make the upper and lower blades 3 contact, thereby reducing the flow of airflow and rainwater between the blades 3. The magnet 5 is fixed to the top of the first sliding groove 201. The magnet 5 can pass The magnetic field attracts the metal pressure rod 4 to move upward in the first slide groove 201. Two water diversion grooves 202 and a plurality of second slide grooves 203 respectively connected to the two water diversion grooves 202 are provided in the door 2. The second slide grooves 203 and the non-magnetic sliding plate 6 are arranged in a one-to-one correspondence with the first slide groove 201. The two ends of the water diversion groove 202 are respectively connected to the outside world at the top and bottom of the door 2. The non-magnetic sliding plate 6 is slidably connected to the corresponding second slide groove 203. One end of the first return spring 601 is fixed in the second slide groove 203. The first The other end of the return spring 601 is fixed to the non-magnetic sliding plate 6, the nickel-iron sliding plate 7 is fixed to the non-magnetic sliding plate 6, the nickel-iron sliding plate 7 is slidingly connected to the door 2, the nickel-iron sliding plate 7 is located between the metal pressure rod 4 and the magnet 5, and the nickel-iron sliding plate 7 has a high magnetic permeability, so that the nickel-iron sliding plate 7 can hinder the propagation of the magnetic field of the magnet 5, thereby reducing the adsorption force of the magnet 5 on the metal pressure rod 4, and the wind force regulating unit is arranged on the door 2, which is used to limit the airflow flowing into the box-type substation 1 by adjusting the inclination angle of the blade 3 by wind force.

[0020] like Figure 4 As shown, it also includes a wedge block 8 and a buoyancy plate 9. The wedge block 8 is fixed to the side of the non-magnetic sliding plate 6 away from the first return spring 601, and the wedge block 8 is located below the corresponding metal pressure rod 4. The buoyancy plate 9 corresponds to the wedge block 8 one by one. The buoyancy plate 9 is slidably set in the water diversion groove 202. The top of the buoyancy plate 9 is provided with a chamfer so that the buoyancy plate 9 matches the inclined surface of the corresponding wedge block 8, so that the wedge block 8 is squeezed by the buoyancy plate 9, so that the wedge block 8 drives the nickel-iron sliding plate 7 to move along the setting direction of the second slide groove 203 through the non-magnetic sliding plate 6, so that the nickel-iron sliding plate 7 extends between the metal pressure rod 4 and the magnet 5, thereby weakening the magnetic field between the metal pressure rod 4 and the magnet 5, thereby changing the position of the metal pressure rod 4 by adjusting the magnetic force received by the metal pressure rod 4.

[0021] like Figure 4 As shown, a sealing strip is fixed to one side of the bottom of each blade 3 , and adjacent blades 3 can contact each other through the sealing strip, preventing moisture and rainwater from entering the box-type substation 1 through the gaps between adjacent blades 3 .

[0022] like Figure 4 As shown, it also includes a water absorption sleeve 10, which is fixed to the outer wall of the metal pressure rod 4. The water absorption sleeve 10 is a porous structure that can absorb rainwater to increase its own weight, so that the water absorption sleeve 10 further presses the blades 3 downward to rotate.

[0023] like Figure 5-Figure 6 As shown, it also includes a first temperature-sensitive spring 11. A first cylindrical cavity 204 corresponding to the blade 3 is opened on one side of the door 2. A first temperature-sensitive spring 11 is provided in each of the first cylindrical cavities 204. One end of the first temperature-sensitive spring 11 is fixedly connected to the corresponding first cylindrical cavity 204, and the other end of the first temperature-sensitive spring 11 is fixedly connected to the corresponding blade 3. When the first temperature-sensitive spring 11 absorbs the heat radiation generated by the operation of the substation equipment, its own temperature will increase, thereby deforming and driving the blade 3 to rotate, increasing the gap between two adjacent blades 3, thereby increasing the air flow between adjacent blades 3. In addition, the first temperature-sensitive spring 11 has the effect of driving the blade 3 to reset when it is not squeezed by the water absorption sleeve 10. If the water absorption sleeve 10 squeezes the blade 3, the elastic force of the first temperature-sensitive spring 11 cannot overcome the squeezing of the water absorption sleeve 10 on the blade 3, thereby preventing rainwater from entering the box-type substation 1.

[0024] like Figure 6 As shown, a ventilation groove 205 corresponding to the first cylindrical cavity 204 is opened on one side of the door 2. The ventilation groove 205 is connected to the first cylindrical cavity 204 and the interior of the box-type substation 1, so that the heat generated by the substation equipment during operation can be transmitted to the first temperature-sensitive clockwork spring 11 through the ventilation groove 205.

[0025] like Figure 2 and Figure 7-10As shown, the wind regulating unit is used to limit the airflow into the box-type substation 1 by adjusting the inclination angle of the wind-force-adjusting blades 3. The wind regulating unit includes: a cylindrical sheath 12, a sealing cylinder 13, a piston plate 14, a rotating support cylinder 15, a hose 16, a piston cylinder 17, a piston rod 18, a rack 19 and a damping gear 20. The cylindrical sheath 12 is fixed to the upper part of the door 2, the sealing cylinder 13 is located inside the cylindrical sheath 12 and fixed to the upper part of the door 2, the piston plate 14 is slidably connected to the sealing cylinder 13, the rotating support cylinder 15 is fixed to the piston plate 14, the rotating support cylinder 15 is slidably connected to the sealing cylinder 13, the sealing cylinder 13 is filled with hydraulic oil, and the hose 16 is connected. It is fixed to the bottom of the sealing cylinder 13, the piston cylinder 17 is fixed to the door 2, the piston cylinder 17 is connected to the hose 16, the piston rod 18 is slidably connected to the piston cylinder 17, the rack 19 is slidably connected to the door 2 in the vertical direction, the top of the rack 19 is fixed to the piston rod 18, the damping gear 20 is arranged one by one with the blade 3, and the damping gear 20 is connected to the end of the corresponding blade 3 away from the first cylindrical cavity 204 through the one-way damping card of its inner wall. The damping gear 20 can drive the blade 3 to rotate and close the blade 3, and when the torque applied to the blade 3 is large, it will rotate on the damping gear 20, and the outer walls of all damping gears 20 are meshed with the rack 19.

[0026] like Figure 9-10 As shown, the wind force regulating unit also includes a sliding support cylinder 21, fan blades 22, connecting rods 23, counterweights 24 and a second return spring 2101. The sliding support cylinder 21 is slidably arranged on one side of the rotating support cylinder 15. The sliding support cylinder 21 is rotatably connected to the cylindrical sleeve 12. Multiple fan blades 22 are circumferentially distributed and rotatably connected to the sliding support cylinder 21. There are multiple connecting rods 23 on the rotating support cylinder 15 and correspondingly rotatably connected to the sliding support cylinder 21. The multiple connecting rods 23 are distributed in a ring shape. The connecting rod 23 connected to the rotating support cylinder 15 is rotatably connected to the corresponding connecting rod 23 connected to the sliding support cylinder 21 through the counterweight 24. The counterweight 24 can control the position of the rotating support cylinder 15 in the sealing cylinder 13 through the connecting rod 23 based on the centrifugal force it receives during rotation. The second return spring 2101 is fixed between the rotating support cylinder 15 and the sliding support cylinder 21.

[0027] like Figure 11As shown, the wind force regulating unit also includes a second temperature-sensitive clockwork spring 25, which is arranged in a one-to-one correspondence with the fan blades 22, and a third cylindrical cavity 2103 corresponding to the fan blades 22 is circumferentially distributed in the sliding support tube 21. One end of the second temperature-sensitive clockwork spring 25 is fixedly connected to the corresponding third cylindrical cavity 2103, and the other end of the second temperature-sensitive clockwork spring 25 is fixedly connected to the corresponding fan blade 22. The inclination angle of the fan blade 22 can be adjusted based on the temperature change caused by the air humidity. A plurality of cylindrical through holes 2104 are circumferentially distributed on the inner wall of the sliding support tube 21, and the third cylindrical cavity 2103 can be connected to the outside world through the cylindrical through holes 2104.

[0028] like Figure 11 As shown, the wind force regulating unit also includes a reset spring 26, which is arranged in a one-to-one correspondence with the second temperature-sensitive spring 25. A second cylindrical cavity 2102 corresponding to the fan blade 22 is circumferentially distributed in the sliding support tube 21. The reset spring 26 is fixed in the corresponding second cylindrical cavity 2102. The reset spring 26 is fixed to the corresponding fan blade 22. The rotation direction of the reset spring 26 is opposite to that of the corresponding second temperature-sensitive spring 25, and is used to suppress the excessive sensitivity of the second temperature-sensitive spring 25 caused by the influence of temperature, thereby improving the stability of the second temperature-sensitive spring 25 when driving the fan blade 22 to rotate.

[0029] In the initial state, the door 2 is in a closed state, and there is a large gap between adjacent blades 3. The magnet 5 attracts the metal pressure rod 4 by its own magnetic force, so that the metal pressure rod 4 is located at the top of the first slide 201. When the rainfall in the mountainous area is heavy, the water level of the rainfall will rise, and the rainwater will enter the water diversion groove 202 through one end of the water diversion groove 202 at the bottom of the door 2. The buoyancy of the rainwater causes the buoyancy plate 9 to rise in the water diversion groove 202. It is worth noting that at this time, the rainwater level has not reached the bottom of the blade 3. The buoyancy plate 9 squeezes the wedge block 8 upward. After the wedge block 8 is squeezed, the wedge block 8 drives the non-magnetic sliding plate 6 along the setting direction of the second slide 203. The non-magnetic sliding plate 6 drives the nickel-iron sliding plate 7 to move synchronously during the movement, and squeezes the first return spring 601, so that the nickel-iron sliding plate 7 moves between the magnet 5 and the metal pressure rod 4. Since the nickel-iron sliding plate 7 has a high magnetic permeability, the nickel-iron sliding plate 7 has the effect of cutting and blocking the magnetic field. The movement of the nickel-iron sliding plate 7 weakens the magnetic field of the magnet 5, thereby reducing the magnetic force on the metal pressure rod 4. The metal pressure rod 4 slides downward along the first slide groove 201 under the action of gravity, so that the metal pressure rod 4 presses the blade 3 downward through the water absorption sleeve 10. The blade 3 is rotated under pressure, so that the blade 3 overcomes the damping force. The damping between the gears 20 rotates, and causes the blade 3 to drive the first temperature-sensitive clockwork spring 11 to coil and deform, until the sealing strip at the bottom of the blade 3 seals the gap between the upper and lower adjacent blades 3, thereby preventing rainwater from entering the box-type substation 1 through the gap between the upper and lower adjacent blades 3, avoiding the substation equipment in the box-type substation 1 from being soaked by rainwater and causing short-circuit damage to the substation equipment, and reducing the economic losses caused by flood disasters to the construction of power grids in mountainous rural areas. In addition, when the rainwater level is higher than the bottom of the blade 3, the rainwater will further squeeze the blade 3 through water pressure, and the porous structure of the water-absorbing sleeve 10 will absorb moisture when it contacts the rainwater, so that its own gravity becomes The water absorption sleeve 10 further squeezes the blade 3 through the increased gravity, so that the gap between the upper and lower blades 3 is further sealed by the sealing strip, thereby improving the sealing effect of the sealing strip, and further preventing rainwater from entering the box-type substation 1. It is worth noting that although the bottom blade 3 is in a closed state due to the rising water level of the rain, the bottom blade 3 is squeezed by the water pressure of the rainwater and the water absorption sleeve 10, but the blade 3 above the rainwater level is not affected by the rainwater, so that the blade 3 above the rainwater level is still in an open state, thereby ensuring that the substation equipment in the box-type substation 1 can continue to take in air, and ensuring the normal operation of the substation equipment in the box-type substation 1.

[0030] Due to the large changes in mountainous terrain, under the influence of mountainous terrain, on the one hand, the hillsides are heated during the day to form valley winds, and at night the hillsides are cooled to form mountain winds, thereby forming thermal circulation in the mountainous areas. On the other hand, the wind will accelerate in the valley due to the narrow channel effect. Therefore, airflow is more likely to occur in mountainous terrain. When the airflow reaches the cylindrical sheath 12, the airflow will blow the fan blades 22 on the sliding support tube 21, so that the fan blades 22 drive the sliding support tube 21 to rotate, and the rotation of the sliding support tube 21 drives the connecting rod 23 on the sliding support tube 21 to rotate, so that the counterweight block 24 rotates synchronously. The counterweight blocks 24 move away from each other due to centrifugal force during the rotation process, so that the counterweight block 24 drives the connecting rod 23 on the sliding support tube 21 to rotate along the connection between the sliding support tube 21 and the connecting rod 23, and drives the connecting rod 23 on the rotating support tube 15 to rotate along the rotating support tube 15 The connection with the connecting rod 23 rotates, so that the connecting rod 23 on the rotating support cylinder 15 drives the rotating support cylinder 15 to approach the sliding support cylinder 21, and the rotating support cylinder 15 drives the piston plate 14 to move synchronously, thereby increasing the volume inside the sealing cylinder 13, and the hydraulic oil in the piston cylinder 17 enters the sealing cylinder 13 through the hose 16, so that the hydraulic oil in the piston cylinder 17 drives the rack 19 to move upward through the piston rod 18, and the rack 19 moves upward and drives the blades 3 to rotate through the damping gear 20, thereby increasing the gap between adjacent blades 3, facilitating the airflow to flow between adjacent blades 3, thereby facilitating the airflow to pass through the box-type substation 1, taking away the heat generated by the operation of the substation equipment in the box-type substation 1, preventing the safety hazards of the substation equipment in the box-type substation 1 caused by heat accumulation, and ensuring the working safety of the substation equipment in the box-type substation 1.

[0031] When the airflow in mountainous areas is strong, the gap between adjacent blades 3 will increase, thereby improving the flow effect in the box-type substation 1. However, when heavy rain occurs, strong winds and rising rainwater levels will occur at the same time. Although the wind will drive the sliding support cylinder 21 through the fan blades 22 to drive the connecting rod 23 and the counterweight 24 to rotate, and the support cylinder 15 controls the piston rod 18 and the rack 19 through the hydraulic oil to drive the damping gear 20 to rotate, the rising rainwater level will drive the nickel-iron sliding plate 7 through the buoyancy plate 9 to hinder the propagation of the magnetic field of the magnet 5, so that the metal pressure rod 4 and the water absorption sleeve 10 press the blade 3 downward, so that the blade 3 overcomes the damping between the blade 3 and the damping gear 20 and rotates. Therefore, when the wind drives the damping gear 20 to rotate, the damping gear 20 will idle on the blade 3, thereby preventing the damping gear 20 from opening the blade 3 when rotating, thereby preventing the rising rainwater from entering the box-type substation 1 through the gap between adjacent blades 3, thereby ensuring the working safety of the substation equipment in the box-type substation 1.

[0032] At night in mountainous areas, the temperature at night is lower than that during the day, which causes water vapor in the air to condense, resulting in higher humidity in the air. Or when it rains in the mountains, the rain will cause the humidity in the air to rise. Excessive humidity can easily cause water vapor to condense into water droplets in the box-type substation 1 due to the temperature difference between day and night. The water droplets may drip into the substation equipment in the box-type substation 1, causing damage to the substation equipment. Therefore, when the humidity of the air flow is high, the fluidity of the air flow in the box-type substation 1 should be reduced. To this end, when the air flow blows the fan blades 22 to rotate the sliding support cylinder 21, the air flow will also pass through the inner wall of the sliding support cylinder 21. At this time, the flow of the air flow causes the pressure of the surrounding gas to decrease, so that the air flow attracts the surrounding gas to flow toward it through the pressure difference, thereby making the third cylindrical cavity 210 3 is driven by the pressure difference of the air flow, flows into the air flow through the cylindrical through hole 2104, and reduces the air pressure in the third cylindrical cavity 2103. It is worth noting that the water vapor in the mountain air will fill the third cylindrical cavity 2103 through the diffusion phenomenon, and the reduction of the air pressure in the third cylindrical cavity 2103 will accelerate the volatilization of the water in the third cylindrical cavity 2103, so that the temperature of the second temperature-sensitive spring 25 in the third cylindrical cavity 2103 is reduced. The second temperature-sensitive spring 25 is affected by the temperature and is wound up, so that the second temperature-sensitive spring 25 drives the blade 22 to rotate around the connection between the blade 22 and the sliding support tube 21. The rotation of the blade 22 will deform the reset spring 26 and make it easier for the air flow to pass through the blade 22, thereby reducing the friction between the blade 22 and the sliding support tube 21. The rotating force of the dynamic support cylinder 21 reduces the speed of the sliding support cylinder 21. The reduction in the speed of the sliding support cylinder 21 reduces the speed of the connecting rod 23 on the sliding support cylinder 21, thereby causing the counterweight block 24 to decelerate synchronously. The counterweight block 24 reduces the centrifugal force it receives due to the reduction in speed during rotation, thereby causing the counterweight block 24 to reduce the pulling force on the rotating support cylinder 15 through the connecting rod 23. The second return spring 2101 is therefore released to drive the rotating support cylinder 15 to move backward, thereby causing the rotating support cylinder 15 to push the hydraulic oil in the rotating support cylinder 15 through the piston plate 14, so that the hydraulic oil in the rotating support cylinder 15 enters the piston cylinder 17 through the hose 16, and the hydraulic oil in the piston cylinder 17 drives the rack 19 to move downward through the piston rod 18, and the rack 19 moves downward through The damping gear 20 drives the blades 3 to rotate, thereby reducing the gaps between adjacent blades 3, inhibiting the airflow from entering the box-type substation 1, thereby reducing the humidity caused by the airflow in the box-type substation 1, and when the airflow enters the box-type substation 1 through the gaps between adjacent blades 3, the water vapor in the airflow will be adsorbed by the porous structure of the water absorption sleeve 10, thereby preventing the water vapor from condensing in the box-type substation 1 and damaging the substation equipment, further ensuring the working safety of the substation equipment in the box-type substation 1, and when it rains in the mountainous area, the airflow will flow along the reduced gaps between adjacent blades 3, so that the airflow flows upward along the surface of the adjacent blades 3 into the box-type substation 1, and the rainwater will drip on the blades 3 due to gravity and gather on the blades 3, thereby forming small streams of water.And it flows downward along the blades 3, thereby blocking the rainwater outside the box-type substation 1, thereby ensuring the working safety of the substation equipment inside the box-type substation 1.
