Description

Technical Field

[0002] Energy efficiency testing of power equipment is the core technology to evaluate the efficiency of power equipment in the process of energy conversion, transmission and use. It aims to optimize energy utilization efficiency, reduce carbon emissions and meet the requirements of global sustainable development. As the world is currently promoting energy conservation and emission reduction, energy efficiency testing of power equipment has become particularly important.

[0003] The prior art provides an energy efficiency test platform for electric equipment (publication number CN116087645A), comprising: a controller; a power supply platform; a power connection assembly; a test platform, located above the power connection assembly, comprising a power connection metal sleeve, the test platform is lifted and lowered relative to the power connection assembly and switched between a conducting position and a disconnecting position; the power connection assembly comprises a fixed column and a deformable metal sleeve slidably connected to the upper part of the fixed column; when the deformable metal sleeve is located in the power connection metal sleeve and contacts the inner side wall of the power connection metal sleeve, the test platform is in the conducting position, and when the power connection metal sleeve rises and separates from the deformable metal sleeve, the test platform is in the disconnecting position;

[0004] In the above scheme and the prior art, for the energy efficiency test equipment, the energy efficiency test depends on the cooperation of many electronic devices inside the equipment, especially sensors of various precisions.

When used in some humid areas, most of them will be equipped with electric contact anti-oxidation devices to prevent the electronic devices and sensors from getting damp, so as to maintain a constant humidity and avoid data deviation.

DETAILED DESCRIPTION

[0030] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0031] The invention provides Figures 1 to 7 An energy efficiency test cabinet shown includes a cabinet body 1 , a refrigeration side heat meter 2 and a cooling side heat meter 3 are installed inside the cabinet body 1 , and a touch screen 4 and an electric meter 5 are embedded on the surface of the cabinet body 1 .

[0032] See also Figure 1 and Figure 2When conducting energy efficiency tests on power equipment, the touch screen 4 can be used for operators to output instructions and provide data feedback for the entire system. The electric meter 5 can be used to observe the power consumption of the power equipment, while the refrigeration side heat meter 2 and the cooling side heat meter 3 are used for energy efficiency tests on some power equipment that can produce temperature changes. Since the energy efficiency test of power equipment requires the coordinated work of all precision instruments in the cabinet 1 including the touch screen 4 and the electric meter 5, it is necessary to ensure that the instruments inside the cabinet 1 will not be affected by the external environment, especially the influence of water vapor in a high humidity environment, during the energy efficiency test.

[0033] A box body 6 is fixedly installed on the back of the cabinet body 1, and the top of the box body 6 is connected to the interior of the cabinet body 1 through a pipe 7. A first fan 33 is vertically embedded in the side of the box body 6, and a second fan 34 is horizontally fixedly installed between the two first partitions 8. Two first partitions 8, two second partitions 9 and two third partitions 10 are fixedly installed on the inner wall of the cabinet body 1. An anti-static device is arranged between the third partition 10 and the second partition 9, a preliminary processing device is arranged between the second partition 9 and the box body 6, and an electrical contact anti-oxidation device is arranged between the two second partitions 9.

[0034] See also Figure 1 , the external gas is introduced into the box body 6 through the first fan 33, and finally sent into the pipe 7 through the second fan 34, so that the gas enters the cabinet body 1 through the pipe 7. In this process, the gas first passes through the anti-static device inside the box body 6, and the large particles of dust in the gas can be filtered through the anti-static device. The filtered gas enters the preliminary treatment device for heating. In this process, the gas can be dehumidified to a certain extent. Finally, the heated gas enters the electric contact anti-oxidation device for more thorough dehumidification. The dehumidified gas can normally enter the cabinet body 1, so that the energy efficiency test of the power equipment can be carried out normally.

[0035] The anti-static device includes a frame 27 and a second filter screen 28. The second filter screen 28 is embedded in the inner wall of the frame 27. The frame 27 is detachably installed between the third partition 10 and the second partition 9. The frame 27 and the second filter screen 28 are parallel to the horizontal plane. The surfaces of the third partition 10 and the second partition 9 are both provided with slide grooves 31. The two sides of the frame 27 are respectively slidably connected to the inside of the two slide grooves 31.

[0036] See also Figure 3 and Figure 4When the gas passes through the second filter 28, the second filter 28 can intercept large particles of dust in the air. In this process, the surface of the second filter 28 will inevitably be blocked by impurities in the air. Therefore, in this embodiment, the connection method between the frame 27 and the second partition 9 and the second partition 9 is set to a detachable connection structure, so that the frame 27 and the second filter 28 can be regularly disassembled to clean the surface of the second filter 28, and after opening the box body 6, since the air stops entering the inside of the box body 6 at this time, some impurities on the surface of the second filter 28 will fall to the bottom of the box body 6 under the action of gravity. When cleaning the second filter 28, these impurities also need to be cleaned.

[0037] The preliminary treatment device includes a shell 29 and an electric heating plate 30. The top and bottom of the shell 29 are both set as open structures. The shell 29 is fixedly installed between the second partition plate 9 and the box body 6. Two electric heating plates 30 are symmetrically fixedly installed on the inner wall of the shell 29.

[0038] The preliminary treatment device can then perform preliminary drying on the gas to prevent the gas from being too humid, which can not only reduce the risk of leakage of electrical equipment caused by excessive humidity, but also reduce the overall energy loss, so that the energy efficiency test of the electrical equipment can be carried out normally.

[0039] See also Figure 3 and Figure 5 After being filtered, the gas will enter the interior of the shell 29. When passing through the shell 29, the gas will contact the electric heating plate 30. The heat generated by the electric heating plate 30 when working can heat the air. In this process, part of the moisture in the air will evaporate due to the heating, thereby achieving the function of preliminary dehumidification, and the temperature of the heated gas will rise, so that when the energy efficiency test cabinet is used in cold areas, the inside of the cabinet 1 can be kept at a normal working temperature.

[0040] High humidity will reduce the performance of insulating materials in electrical equipment, increase leakage current, and lead to increased energy loss. It will also hinder the heat dissipation of electrical equipment, causing temperature rise and additional energy consumption. Therefore, an electrical contact anti-oxidation device is provided in this embodiment.

[0041] The electric contact anti-oxidation device comprises a shell 11, a gas channel 12, a dehumidification channel 13, a dehumidification plate 14 and a first filter 15. The shell 11 is installed on the inner wall of the box body 6 and is located between the two second partitions 9. The dehumidification channel 13 and the gas channel 12 are arranged inside the shell 11, and the dehumidification channel 13 and the gas channel 12 are connected to each other. The three dehumidification plates 14 are evenly rotated and arranged inside the dehumidification channel 13 through a traction mechanism. The dehumidification plate 14 is set to a hollow structure. The interior of the dehumidification plate 14 is filled with activated carbon material. The first filter 15 is embedded in the surface of the dehumidification plate 14. The interior of the wet plate 14 is connected to the dehumidification channel 13 through the first filter 15. An air inlet 32 ​​is arranged between the first partition 8 and the second partition 9. The air inlet 32 ​​is connected to the interior of the gas channel 12. The traction mechanism includes a motor 24, a bracket 25 and a drive shaft 26. The two brackets 25 are horizontal to each other and are fixedly installed on the inner wall of the dehumidification channel 13 by screws. The drive shaft 26 is rotatably connected between the two brackets 25. The motor 24 is fixedly installed on the top of one of the brackets 25 and is connected to the top of the drive shaft 26. The three dehumidification plates 14 are evenly fixedly installed on the surface of the drive shaft 26.

[0042] See also Figure 6 The heated gas will enter the gas channel 12 through the air inlet 32 ​​and finally enter the dehumidification channel 13. At this time, the motor 24 can drive the drive shaft 26 to rotate, and the drive shaft 26 can simultaneously drive the three dehumidification plates 14 to rotate in one direction. When the dehumidification plate 14 rotates, it can drive the first filter 15 to rotate synchronously. At this time, the gas can pass through the surface of the first filter 15, thereby contacting the activated carbon material inside the dehumidification plate 14 to achieve the function of dehumidifying the gas. The dehumidified gas can enter the box body 6 again from the dehumidification channel 13, and enter the cabinet body 1 through the pipeline 7 under the transportation of the second fan 34. At this time, the humidity in the gas is greatly reduced, which can reduce the energy loss of power equipment, reduce the corrosion rate of metal parts, and prevent humidity from affecting the accuracy of the test instrument.

[0043] It should be noted that since the activated carbon material is a consumable when used as a drying material and needs to be replaced regularly, in this embodiment, the top bracket 25 can be removed from the interior of the dehumidification channel 13 by removing the screws, and a spline connection is set between the bottom end of the drive shaft 26 and the bottom bracket 25. At this time, the dehumidification plate 14, the drive shaft 26, the motor 24 and the top bracket 25 can be taken out from the interior of the dehumidification channel 13 as a whole. At the same time, a switch that can be repeatedly operated is set at the bottom or top of the dehumidification plate 14 to facilitate the replacement of the activated carbon material inside the dehumidification plate 14.

[0044] In a high humidity environment, condensation (dew condensation) may occur inside the cabinet 1 or on the surface of the cabinet 1 due to temperature differences, causing short circuits in the internal electrical equipment, rust on metal parts, or failure of electronic components. Dehumidification can eliminate the risk of condensation, extend the service life of the electrical equipment, and prevent excessive humidity from affecting the test results of sensors, precision instruments, or electronic products, such as resistance value and signal transmission.

[0045] The dehumidification plate 14 is provided with a storage chamber 16, a feed chamber 17, a lifting chamber 18 and a discharge chamber 19. The storage chamber 16 is connected with the lifting chamber 18 through the feed chamber 17 and the discharge chamber 19. A rotating shaft 20 is provided inside the discharge chamber 19 to rotate along the axial direction. A lifting blade 21 is fixedly installed on the surface of the rotating shaft 20. A driving mechanism is provided between the rotating shaft 20 and the inner wall of the dehumidification channel 13. The driving mechanism includes a gear ring 22 and a gear 23. The two gear rings 22 are fixedly installed on the inner wall of the dehumidification channel 13. The rotating shaft 20 is provided with a gear 23. 0 penetrates the dehumidification plate 14 and extends into the dehumidification channel 13, two gears 23 are fixedly mounted on the two ends of the rotating shaft 20, and the two gears 23 are respectively meshed with the two gear rings 22, the feed chamber 17 is connected to the top of the storage chamber 16 and the lifting chamber 18, and the height of the feed chamber 17 gradually decreases from the storage chamber 16 to the lifting chamber 18, and the discharge chamber 19 is connected to the bottom of the storage chamber 16 and the lifting chamber 18, and the height of the discharge chamber 19 gradually increases from the storage chamber 16 to the lifting chamber 18.

[0046] See also Figure 7 When the driving shaft 26 drives the dehumidification plate 14 to rotate in one direction, the dehumidification plate 14 can drive the gear 23 to revolve through the rotating shaft 20. During this process, the gear 23 is always meshed with the ring gear 22. Therefore, under the drive of the ring gear 22, the rotating shaft 20 can be driven by the gear 23 to continuously rotate in one direction, so that the rotating shaft 20 can drive the lifting blade 21 to continuously rotate in the lifting chamber 18. At this time, the lifting blade 21 can drive the activated carbon material to continuously rise from the bottom, and finally make the activated carbon material reach one end of the feeding chamber 17. At this time, under the gravity and the subsequent activated carbon Under the thrust of the material, this part of the activated carbon material can enter the top of the storage chamber 16 through the feed chamber 17, and the activated carbon material at the bottom of the storage chamber 16 can enter the lifting chamber 18 through the discharge chamber 19 under the action of gravity and the pressure of the activated carbon material above, thereby realizing the unidirectional circulation movement of the activated carbon material. In the above process, since the activated carbon is constantly moving, it can evenly contact the gas inside the dehumidification channel 13, thereby realizing the uniform utilization of the activated carbon material and maximizing the utilization rate of the activated carbon material.

[0047] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
