Description

Technical Field

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

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid.

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

[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, which can compress the incoming air and increase the flow rate of the air at the outlet of the air inlet channel, 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 extreme 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

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also 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, the box-type substation 1 has two opposite side walls:

[0037] The side wall is composed of an outer portion 2 and an inner portion 12, the outer portion 2 and the inner portion 12 are connected by a flexible connection portion 16, and a cavity is formed therein, a ventilation hole 8 is also provided between the outer portion 2 and the inner portion 12, and the ventilation hole 8 is not connected to the cavity between the outer portion 2 and the inner portion 12;

[0038] It also includes a switching assembly, which is used to switch the cavity between the outer portion 2 and the inner portion 12 between a filled state and a deflated state;

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

[0040] In the filled state, the cavity between the outer part 2 and the inner part 12 forms a thermal insulation layer.

[0041] The intelligent energy-saving control type power substation can be installed by a crane or other equipment during installation, and during its use, when the external environment is hot, such as in summer or in hot areas, the switching component switches the cavity between the outer part 2 and the inner part 12 to a deflated state, such as Figure 4As shown in the figure, the outer part 2 is in 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 arrangement of the ventilation holes 8 can also form a through wind in the box-type substation 1 by means of natural wind or adding a fan. In this way, the box-type substation 1 can be maintained at a suitable ambient temperature by means of heat conduction and air heat to ensure the normal operation of the internal components.

[0042] When the external environment is cold, such as in an extreme low temperature environment such as winter, the heat generated in the substation will quickly lose to the surrounding environment, causing the substation to operate 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 filled state, such as Figure 8 As shown in , the outer part 2 and the inner part 12 are in a separated state at this time, and the cavity formed inside can increase the thickness of the side wall on the one hand, and on the other hand, the cavity can form a transfer heat exchange layer, which can not only effectively block the influence of the external low temperature on the internal environment (i.e., heat exchange efficiency), but also slow down the heat loss in the box-type substation 1, so that the box-type substation 1 can still be maintained at a suitable temperature environment under the external extreme low temperature environment, so that the internal electronic devices 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 under different temperature environments, solving the problem of its environmental adaptability. At the same time, there is no need to introduce other unnecessary heating or cooling equipment, which reduces the configuration while making it more applicable.

[0044] In one of the more preferred embodiments, an implementation of a switching component is provided;

[0045] The switching assembly includes a liquid storage tank 9 fixed at 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 installed in the liquid storage tank 9 on the upper and lower sides of the partition 18, respectively. The liquid storage bag 20 is filled with coolant, and the liquid storage bag 20 is connected to the cavity between the outer part 2 and the inner part 12 through a liquid infusion tube 17;

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

[0047] See also Figure 4 , the micro air pump 21 installed in the box-type substation 1 is used to inflate or suck air into the airbag 19, which can drive the partition 18 to rise and fall and slide in the liquid storage tank 9, thereby squeezing or stretching the liquid storage bag 20 to restore;

[0048] When the partition 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 is switched to the filled state, and a heat preservation layer is formed by the coolant, so as to achieve the above-mentioned heat preservation purpose;

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

[0050] On the contrary, when the partition 18 moves downward to stretch and restore the liquid storage bag 20, it will absorb the cooling liquid in the upper cavity through the infusion tube 17, and switch it to a deflated state under the negative pressure inside the cavity, so as to achieve the purpose of improving the thermal conductivity.

[0051] It is worth noting that when the liquid storage bag 20 is restored and the coolant is sucked back, the coolant will be completely sucked back into the liquid storage bag 20, so that the cavity between the outer part 2 and the inner part 12 can maintain a vacuum-like state, so as to ensure the fit between the outer part 2 and the inner part 12, and then ensure the heat conduction effect under the heat dissipation state.

[0052] In addition, the liquid storage tank 9 is buried underground, and the surrounding soil can also be used to keep the liquid storage capsule 20 warm, 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 heat exchange time of the formed warm cavity longer and facilitating heat retention.

[0053] In one of the more preferred embodiments, an implementation method for controlling the inflation and inhalation of the airbag 19 is provided, namely, a triggering method;

[0054] A control box 10 is installed on the side wall of the liquid storage tank 9, and a monitoring sleeve 11 is extended and fixed 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 monitoring liquid. A cross plate 23 is fixed to the inner wall of the control box 10, and 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 columns 26 for limiting the swing rod 24 are installed on the inner walls on both sides of the control box 10, and a trigger switch 27 for controlling the start and stop of the micro air pump 21 is installed on one of the limit columns 26.

[0055] See also Figure 5-6, by filling the monitoring sleeve 11 with a monitoring liquid, which can be a liquid such as water, that is, when it freezes, its volume will increase. 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 to lengthen until the tension spring 25 passes the connection point between the swing rod 24 and the cross plate 23. Only then will the swing rod 24 be driven to swing and switch under the action of the tension spring 25, and make it contact with the trigger switch 27, so as to control the micro air pump 21 to start inflating the airbag 19, thereby completing the purpose of switching to the filled state mentioned above;

[0056] It is worth mentioning that since the water or other monitoring liquid in the monitoring sleeve 11 will take a process when it freezes when it is cold, the process of pushing the piston rod 22 is a slow push process. In this way, if the outside temperature fluctuates only within a small range, that is, the water in the monitoring sleeve 11 has not yet completely frozen but has thawed again, then it is equivalent to the piston rod 22 making a small reciprocating movement 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, so that the subsequent state switching will not be completed. In this way, the setting of the tension spring 25 can make the piston rod 22 fluctuate within a small range, avoiding immediate state switching when a small temperature change occurs, and preventing the box-type substation 1 from switching to the insulation state after the external ambient temperature rises. In this way, the physical changes of the monitoring liquid can be used to achieve the purpose of intelligent regulation.

[0057] In this way, when the outside temperature drops to above the preset value, when the water in the monitoring sleeve 11 is completely frozen and has not thawed again, it means that the outside ambient temperature is already extremely cold. At this time, the tension spring 25 will cross the connection point between the swing rod 24 and the cross plate 23, thereby completing the subsequent state switching.

[0058] It is worth noting that the control box 10 can be buried underground like the liquid storage tank 9, and the monitoring sleeve 11 is inserted into the underground soil. When the soil temperature on the ground drops to the point where the water in the monitoring sleeve 11 can be completely frozen, it means that the external ambient temperature has also dropped to a point sufficient for state switching, thereby avoiding the situation where the box-type substation 1 switches to the insulation state after the external ambient temperature rises.

[0059] In one of the more preferred embodiments, a heat dissipation fin 3 is rotatably installed on the outer wall of the outer part 2 near the ventilation hole 8, and a lifting frame 4 is also vertically slidably installed on the outer wall of the outer part 2, and a connecting rod 7 is rotatably connected between the lifting frame 4 and the heat dissipation fin 3, a pull rope 5 is connected to the top of the lifting frame 4, one end of the pull rope 5 is inserted into the outer part 2 and fixed to the edge of the inner part 12, and 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 portion 2 and the inner portion 12 is in a deflated state, the outer portion 2 and the inner portion 12 will fit together to improve the heat exchange efficiency, and at the same time, when the inner portion 12 approaches the outer portion 2, the lifting frame 4 will be pulled up by the pull rope 5, and the heat dissipation fins 3 will stand up under the connection of the connecting rod 7, and the ventilation holes 8 will be opened. In this way, the heat dissipation fins 3 can also be used to increase the contact area with the air, thereby increasing the rate of external heat exchange, and the air flow of the ventilation holes 8 can accelerate the dissipation of heat, thereby improving the heat dissipation effect in the heat dissipation state;

[0061] When the cavity between the outer portion 2 and the inner portion 12 is filled, the inner portion 12 will move away from the outer portion 2 and no longer exert tension on the pull rope 5. At this time, the lifting frame 4 will move down and reset under the tension of the elastic member 6, so that the heat dissipation fins 3 rotate under the action of the connecting rod 7 and fit with the outer portion 2, closing the ventilation holes 8 and reducing the contact area between the ventilation holes and the air, thereby preparing for the subsequent creation of a heat preservation environment.

[0062] In this way, 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 by changing the state of the cavity between the outer portion 2 and the inner portion 12.

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

[0064] In one of the more preferred embodiments, the heat dissipation fin 3 is composed of a heat-conducting portion 15 and an outer package portion 14 wrapped thereout, the heat-conducting portion 15 faces one side of the ventilation hole 8 and contacts with the outer wall of the outer portion 2 for heat conduction.

[0065] See also Figure 8 By arranging the heat-conducting part 15 and the outer package part 14, the heat-conducting part 15 can improve the heat exchange efficiency with the air in the heat dissipation state, and at the same time, the outer package part 14 can improve the sealing effect of the ventilation hole 8 when it is folded, so as to ensure the heat preservation effect of the internal greenhouse environment.

[0066] In one of the more preferred embodiments, a heat conducting sheet 13 is provided on the inner wall of the inner portion 12 , and a hole for the ventilation hole 8 to be contracted and adjusted is provided on the heat conducting sheet 13 .

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

[0068] See also Figure 4 The setting of the heat conducting sheet 13 can improve the efficiency. At the same time, the holes designed thereon provide space for the contraction of the ventilation holes 8. The ventilation holes are preferably in the form of bellows, which can be compressed or stretched along the axial direction.

[0069] In one of the more preferred embodiments, the remaining side walls of the box-type substation 1 are all provided with an internal thermal insulation layer, and a regulating fan is also installed inside the box-type substation 1.

[0070] A fan may also be installed in the box-type substation 1 to assist in forming a through wind inside the substation 1, thereby preventing the natural wind from being too slow to quickly carry away the heat.

[0071] In one of the more preferred embodiments, corresponding magnetic buckles are provided between the interior of the outer packaging portion 14 and the outer wall of the outer portion 2. The magnetic buckles are designed to make the outer packaging portion 14 fit more closely when in contact with the outer portion 2, thereby achieving better heat preservation.

[0072] In one of the more preferred embodiments, the two ends of the connecting rod 7 are configured as a wide end and a narrow end, and when the heat dissipating fin 3 is in contact with the outer portion 2 , the connection points at the two ends of the connecting rod 7 are not located on the same vertical line.

[0073] As can be seen from the previous content, the function of the connecting rod 7 is to enable the lifting frame 4 to drive the heat dissipation fins 3 to rotate during the movement. Therefore, when the heat dissipation fins 3 are in contact with the outer portion 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 to be a wide head and a narrow head, and the contact positions at both ends of the connecting rod 7 are not on the same vertical line to prevent a stuck state with zero torque.

[0074] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
