Description

Technical Field

[0001] The present invention relates to the technical field of power substations, and in particular to an intelligent energy-saving control type power substation. Background Art

[0002] A substation is a location within a power system that transforms voltage and current, receives electricity, and distributes it. The substation within a power plant is a step-up substation, whose function is to boost the voltage of electricity generated by the generator and feed it into the high-voltage grid.

[0003] Among them, the box-type substation, also known as the prefabricated substation or prefabricated substation, is an integrated and compact substation facility. It usually integrates transformers, distribution equipment, protection devices and control systems in one box to save space. However, due to its compact design and dense internal equipment, heat dissipation is a problem that needs special consideration.

[0004] For example, Chinese patent CN117458301B discloses an intelligent solar photovoltaic box-type substation, which forms an air inlet channel with a large inlet and a small outlet under the composition of left and right fan blades. The air inlet channel can be compressed and the air flow rate at the outlet of the air inlet channel can be increased, so that the heat of the electrical components inside the box can be transferred to the air more quickly, thereby achieving the purpose of improving the heat dissipation efficiency of the electrical components.

[0005] However, the increase in heat conduction efficiency also leads to a decrease in its own thermal insulation effect. When in a cold environment, such as an extremely low temperature environment in winter, the heat generated in the substation will quickly lose to the surrounding environment, causing the substation to operate in a low temperature environment. This will also cause damage to the internal components, increasing the probability of failure of internal electronic devices and causing circuit failures. Summary of the Invention

[0006] The object of the present invention is to provide an intelligent energy-saving control type power substation to solve at least one technical problem existing in the above-mentioned prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent energy-saving control type power substation, comprising a box-type substation having two opposite side walls:

[0008] The side wall is composed of an outer portion and an inner portion, the outer portion and the inner portion are connected by a flexible connection portion, and a cavity is formed therein. A ventilation hole is also opened between the outer portion and the inner portion, and the ventilation hole is not connected to the cavity between the outer portion and the inner portion;

[0009] It further includes a switching component for switching the cavity between the outer part and the inner part between a filled state and a deflated state;

[0010] In the deflated state, the outer part is in close contact with the inner part to improve the heat conduction efficiency;

[0011] In the filled state, the cavity between the outer part and the inner part forms a heat insulation layer.

[0012] Preferably, the switching component includes a liquid storage tank fixed at the bottom of the box-type substation, and the liquid storage tank is buried underground. A partition is slidably installed in the liquid storage tank. An air bag and a liquid storage bag are respectively installed in the liquid storage tank on both sides of the partition. The liquid storage bag is filled with a coolant, and the liquid storage bag is communicated with the cavity between the outer part and the inner part through a liquid delivery pipe;

[0013] The switching component further includes a micro air pump installed in the box-type substation, and the micro air pump can adjust the inflation and suction of the air bag.

[0014] Preferably, a control box is installed on the side wall of the liquid storage tank. A monitoring sleeve extends and is fixed on the outer wall of the control box. A piston rod extending into the control box is slidably installed on the inner wall of the monitoring sleeve. The monitoring sleeve is filled with a monitoring liquid. A cross plate is fixed on the inner wall of the control box. A swing rod is rotatably installed on the outer wall of the cross plate. A tension spring is connected between the piston rod and the swing rod. Limit columns for limiting the swing rod are installed on both inner walls of the control box. A trigger switch for controlling the start and stop of the micro air pump is installed on one of the limit columns.

[0015] Preferably, a heat dissipation fin is rotatably installed on the outer wall of the outer part near the ventilation hole. A lifting frame is also vertically slidably installed on the outer wall of the outer part. A connecting rod is rotatably connected between the lifting frame and the heat dissipation fin. A pull rope is connected to the top of the lifting frame. One end of the pull rope penetrates into the outer part and is fixed to the edge of the inner part. A elastic member is connected between the bottom of the lifting frame and the protrusion at the bottom of the box-type substation.

[0016] Preferably, the heat dissipation fin is composed of a heat conduction part and an outer wrapping part wrapped outside it. The heat conduction part faces the ventilation hole and is in thermal contact with the outer wall of the outer part.

[0017] Preferably, heat conduction sheets are provided on the inner wall of the inner part, and holes for adjusting the shrinkage of the ventilation holes are provided on the heat conduction sheets.

[0018] Preferably, internal heat insulation layers are provided on the remaining side walls of the box-type substation, and an adjusting fan is also installed inside the box-type substation.

[0019] Preferably, the ventilation hole adopts a corrugated pipe type for telescopic adjustment.

[0024] Second, the present invention monitors the external temperature environment by monitoring the physical state of the water in the monitoring sleeve, and the setting of the tension spring can make the piston rod fluctuate within a small range, avoiding immediate state switching when there are small temperature changes in the external temperature environment, and preventing the situation that the box-type substation switches to the heat preservation state after the external environmental temperature rises.

[0025] Third, the present invention can change the state of the heat dissipation fins by changing the cavity state between the outer side portion and the inner side portion, thereby improving the heat dissipation effect in the heat dissipation state and improving the heat preservation effect in the heat preservation state.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 8 , the present invention provides a technical solution: an intelligent energy-saving control type power substation, including a box-type substation 1, and the box-type substation 1 has two opposite side walls:

[0037] The side wall is composed of an outer part 2 and an inner part 12. The outer part 2 and the inner part 12 are connected by a flexible connecting part 16, and a cavity is formed inside. A ventilation hole 8 is also penetrated and opened between the outer part 2 and the inner part 12, and the ventilation hole 8 is not communicated with the cavity between the outer part 2 and the inner part 12;

[0038] It further includes a switching component, and the switching component is used to switch the cavity between the outer part 2 and the inner part 12 between a full state and a deflated state;

[0039] In the deflated state, the outer part 2 and the inner part 12 are in close contact to improve the heat conduction efficiency;

[0040] In the full state, a heat insulation layer is formed in the cavity between the outer part 2 and the inner part 12.

[0041] When the intelligent energy-saving control type power substation is installed, it can be installed by equipment such as a crane, and during its use, when the external environment is relatively hot, for example, when used in summer or in a hot area, the switching component will switch the cavity between the outer part 2 and the inner part 12 to the deflated state, as Figure 4As shown, the outer part 2 is brought into fitting contact with the inner part 12 to reduce the overall thickness of the side wall and improve the heat conduction efficiency. At the same time, the ventilation holes 8 can also form a cross-ventilation in the box-type substation 1 by means of natural wind or adding a fan. In this way, by using the methods of heat conduction and air heat transfer, the temperature inside the box-type substation 1 can be maintained at a suitable ambient temperature to ensure the normal operation of the internal components;

[0042] When the external environment is relatively cold, such as in extreme low-temperature environments like winter, the heat generated inside the substation will quickly dissipate to the surrounding environment, resulting in the substation operating in a low-temperature environment. At this time, the switching component will switch the cavity between the outer part 2 and the inner part 12 to a full state, as Figure 8 shown. At this time, the outer part 2 and the inner part 12 are in a separated state. On the one hand, the cavity formed inside can increase the thickness of the side wall. On the other hand, the cavity can form an intermediate heat exchange layer, which can not only effectively block the influence of the external low temperature on the internal environment (i.e., the heat exchange efficiency), but also slow down the heat dissipation inside the box-type substation 1, so that the temperature inside the box-type substation 1 can still be maintained at a suitable temperature environment under extreme low-temperature external environments, and then the internal electronic components can operate normally;

[0043] In this way, by switching the state of the inner cavity between the outer part 2 and the inner part 12 through the switching component, the box-type substation 1 can operate normally in different temperature environments, solving the problem of its environmental adaptability. At the same time, there is no need to introduce other redundant heating or cooling equipment, reducing the configuration while making its application range wider.

[0044] In one relatively preferred embodiment, an implementation manner of the switching component is provided;

[0045] The switching component includes a liquid storage tank 9 fixed to the bottom of the box-type substation 1, and the liquid storage tank 9 is buried underground. A partition 18 is slidably installed in the liquid storage tank 9. An air bag 19 and a liquid storage bag 20 are respectively installed in the liquid storage tank 9 on the upper and lower sides of the partition 18. The liquid storage bag 20 is filled with a coolant, and the liquid storage bag 20 is communicated with the cavity between the outer part 2 and the inner part 12 through a liquid delivery pipe 17;

[0046] The switching component further includes a micro air pump 21 installed in the box-type substation 1, and the micro air pump 21 can perform inflation and suction adjustment on the air bag 19.

[0047] Referring to Figure 4 , by using the micro air pump 21 installed in the box-type substation 1 to inflate or suck air into the air bag 19, the partition 18 can be driven to lift and slide in the liquid storage tank 9, so as to squeeze or stretch and restore the liquid storage bag 20;

[0048] When the partition plate 18 squeezes the liquid storage bag 20, the coolant inside it will be injected into the cavity between the outer part 2 and the inner part 12 through the infusion tube 17 until it is full, and then it will switch to the full state. The coolant is used to form a heat insulation layer to achieve the above-mentioned heat insulation purpose;

[0049] It is worth mentioning that since the specific heat capacity of the liquid is larger than that of the air, the heat insulation effect of the coolant is better than that of the air filling the cavity. And antifreeze can be added to the coolant to prevent it from freezing in a low-temperature environment and affecting its flow effect;

[0050] On the contrary, when the partition plate 18 moves downward to stretch and restore the liquid storage bag 20, it will suck back the coolant in the upper cavity through the infusion tube 17, and switch it to the deflated state under the negative pressure state inside the cavity to achieve the above-mentioned purpose of improving the heat conduction efficiency;

[0051] It should be noted that when the liquid storage bag 20 is restored and sucks back the coolant again, the coolant will be completely sucked back into the liquid storage bag 20. In this way, the cavity between the outer part 2 and the inner part 12 can maintain a quasi-vacuum state to ensure the fitting state between the outer part 2 and the inner part 12, and further ensure the heat conduction effect in the heat dissipation state.

[0052] Moreover, the liquid storage tank 9 is buried underground, and the surrounding soil can also play a role in heat insulation for the liquid storage bag 20, so that the temperature will not be too low after it is squeezed into the cavity between the outer part 2 and the inner part 12, making the formed temperature cavity have a longer heat exchange time and facilitating the retention of heat.

[0053] In one relatively preferred embodiment, an implementation manner for controlling the inflation and deflation of the above-mentioned airbag 19, that is, the triggering manner, is provided;

[0054] A control box 10 is installed on the side wall of the liquid storage tank 9. A monitoring sleeve 11 is fixedly extended on the outer wall of the control box 10. A piston rod 22 extending into the control box 10 is slidably installed on the inner wall of the monitoring sleeve 11. And the monitoring sleeve 11 is filled with a monitoring liquid. A cross plate 23 is fixed on the inner wall of the control box 10. A swing rod 24 is rotatably installed on the outer wall of the cross plate 23. A tension spring 25 is connected between the piston rod 22 and the swing rod 24. And limit posts 26 for limiting the swing rod 24 are installed on both inner walls of the control box 10. A trigger switch 27 for controlling the start and stop of the micro air pump 21 is installed on one of the limit posts 26.

[0055] See Figures 5 - 6, by filling the monitoring sleeve 11 with a monitoring liquid, which can be a liquid such as water, i.e., its volume will increase when it freezes. Therefore, when the monitoring liquid in the monitoring sleeve 11 freezes, the expansion of the volume will push the piston rod 22 to move outward. During the movement of the piston rod 22, the tension spring 25 will be pulled and stretched until the tension spring 25 crosses the connection point between the swing rod 24 and the cross plate 23. Only then, under the action of the tension spring 25, will it drive the swing rod 24 to swing and switch, and make it contact the trigger switch 27, thereby controlling the start of the micro air pump 21 to inflate the airbag 19, and then achieving the above-mentioned purpose of switching to the inflated state;

[0056] It is worth mentioning that since the monitoring liquid such as water in the monitoring sleeve 11 will have a process when it gets cold and freezes, the process of pushing the piston rod 22 is a slow push process. In this way, if the external temperature only fluctuates within a small range, that is, when the water in the monitoring sleeve 11 has not completely frozen and has thawed again, it is equivalent to the piston rod 22 making small reciprocating movements in the monitoring sleeve 11, and the range of this movement will not cause the tension spring 25 to cross the connection point between the swing rod 24 and the cross plate 23, which also means that the subsequent state switch will not be completed. In this way, the setting of the tension spring 25 can enable the piston rod 22 to fluctuate within a small range, avoiding immediately switching the state when there is a small temperature change, and preventing the situation that after the external environmental temperature rises, the box-type substation 1 switches to the heat preservation state. In this way, the physical change of the monitoring liquid can be used to achieve the purpose of intelligent regulation.

[0057] In this way, when the external temperature drops below the preset value, and at this time the water in the monitoring sleeve 11 is completely frozen and has not thawed again, it indicates that the external environmental temperature has reached an extremely cold situation. At this time, the tension spring 25 will cross the connection point between the swing rod 24 and the cross plate 23, and then complete the subsequent state switch.

[0058] It should be noted that the control box 10 can also be buried underground like the liquid storage tank 9, and the monitoring sleeve 11 penetrates into the soil underground. When the soil temperature on the ground drops to make the water in the monitoring sleeve 11 completely freeze, it means that the external environmental temperature has also dropped to a level sufficient for state switching, and it can also avoid the situation that after the external environmental temperature rises, the box-type substation 1 switches to the heat preservation state.

[0059] In one relatively preferred embodiment, a heat dissipation fin 3 is rotatably installed on the outer wall of the outer part 2 close to the ventilation hole 8. A lifting frame 4 is also vertically slidably installed on the outer wall of the outer part 2. A connecting rod 7 is rotatably connected between the lifting frame 4 and the heat dissipation fin 3. A pulling rope 5 is connected to the top of the lifting frame 4. One end of the pulling rope 5 penetrates into the outer part 2 and is fixed to the edge of the inner part 12. An elastic member 6 is connected between the bottom of the lifting frame 4 and the protrusion at the bottom of the box-type substation 1.

[0060] As can be seen from the previous content, when the cavity between the outer part 2 and the inner part 12 is in a deflated state, the outer part 2 and the inner part 12 will fit together to improve the heat exchange efficiency. At the same time, when the inner part 12 approaches the outer part 2, the lifting frame 4 will be pulled up by the pull rope 5. Under the connection of the connecting rod 7, the heat dissipation fins 3 will stand up and open the ventilation holes 8. In this way, the heat dissipation fins 3 can also increase the contact area with the air, improve the rate of external heat exchange, and cooperate with the air flow through the ventilation holes 8 to accelerate the heat dissipation and improve the heat dissipation effect in the heat dissipation state;

[0061] When the cavity between the outer part 2 and the inner part 12 is in a full state, the inner part 12 will move away from the outer part 2 and no longer apply a pulling force to the pull rope 5. At this time, the lifting frame 4 will move down and reset under the pulling force of the elastic member 6, so that the heat dissipation fins 3 will rotate and fit with the outer part 2 under the action of the connecting rod 7, closing the ventilation holes 8 and reducing the contact area with the air at the same time, providing preparation for the subsequent creation of a heat preservation environment;

[0062] In this way, by changing the state of the cavity between the outer part 2 and the inner part 12, the heat dissipation effect can be improved in the heat dissipation state, and the heat preservation effect can be improved in the heat preservation state.

[0063] The elastic member 6 can be a elastic rope or a tension spring, etc., preferably a tension spring, which can adapt to more severe environmental conditions.

[0064] In a more preferred embodiment, the heat dissipation fin 3 is composed of a heat conduction part 15 and an outer wrapping part 14 wrapped outside it. The heat conduction part 15 faces the side of the ventilation hole 8 and is in contact with the outer wall of the outer part 2 for heat conduction.

[0065] See Figure 8 , through the setting of the heat conduction part 15 and the outer wrapping part 14, the heat conduction part 15 can improve the heat exchange efficiency with the air in the heat dissipation state, while the outer wrapping part 14 can improve the closing effect on the ventilation hole 8 when it is folded to ensure the heat preservation effect of the internal greenhouse environment.

[0066] In a more preferred embodiment, a heat conduction sheet 13 is provided on the inner wall of the inner part 12, and a hole for the contraction adjustment of the ventilation hole 8 is provided on the heat conduction sheet 13.

[0067] The ventilation hole 8 adopts a bellows type for telescopic adjustment.

[0068] See Figure 4 , the setting of the heat conduction sheet 13 can improve the efficiency. At the same time, the holes designed on it provide space for the contraction of the ventilation hole 8. The ventilation hole is preferably in the form of a bellows and can be compressed or stretched along the axis.

[0069] In one relatively preferred embodiment, internal heat insulation layers are provided on the remaining side walls of the box-type substation 1, and an adjusting fan is also installed inside the box-type substation 1.

[0070] A fan can also be installed inside the box-type substation 1 to provide assistance for forming a through draft inside it, preventing the natural wind speed outside from being too small to quickly carry away the heat.

[0071] In one relatively preferred embodiment, corresponding magnetic buttons are provided between the interior of the outer wrapping part 14 and the outer wall of the outer side part 2. The design of the magnetic buttons is to make the outer wrapping part 14 fit more closely to the outer side part 2 when they are in contact, achieving a better heat insulation effect.

[0072] In one relatively preferred embodiment, the two ends of the connecting rod 7 are designed as a wide head and a narrow head, and when the heat dissipation fins 3 are in contact with the outer side part 2, the contact positions of the two ends of the connecting rod 7 are not on the same vertical line.

[0073] As can be known from the previous content, the function of the connecting rod 7 is to drive the heat dissipation fins 3 to rotate when the lifting frame 4 moves. Therefore, when the heat dissipation fins 3 are in contact with the outer side part 2, in order to prevent the connecting rod 7 from getting stuck when the lifting frame 4 moves, the two ends of the connecting rod 7 are designed as a wide head and a narrow head, and the contact positions of the two ends of the connecting rod 7 are not on the same vertical line to prevent the stuck state with a zero moment.

[0074] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed without any doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0075] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
