Description

Technical Field

[0001] The present application relates to the technical field of power equipment, and in particular to a power distribution cabinet with environmental detection and regulation functions. Background Art

[0002] A distribution cabinet, also known as a distribution box, is divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). It is the final stage of the power distribution system. A distribution cabinet houses electrical equipment such as power switches, air relays, timers, contactors, and circuit breakers. During operation, these devices, due to their inherent resistance, convert some electrical energy into heat energy that diffuses into the distribution cabinet. This heat, generated by these devices, raises the temperature inside the cabinet, affecting the normal operation of the electrical equipment. Therefore, ventilation holes are typically provided in the distribution cabinet to exhaust the hot air inside the cabinet to the outside, thereby dissipating heat and cooling the electrical equipment inside. However, this natural ventilation heat exchange method has limited heat exchange capacity.

[0003] Furthermore, existing distribution cabinets lack a humidity detection and processing module. During use, air from the external environment can enter the cabinet. This high humidity reduces the insulation strength of the electrical equipment within. High-humidity air has lower insulation performance, and many parts of switchgear rely on air gaps for insulation. Furthermore, moisture in the air adheres to the surface of the insulating material, reducing the insulation resistance of electrical equipment. This is especially true for older equipment, where internal dust accumulation absorbs moisture, leading to even more severe humidity and even lower insulation resistance. This significantly increases the leakage current of the equipment, potentially causing insulation breakdown and accidents. Furthermore, humid air within the electrical cabinet can corrode the conductive metal, magnetic silicon steel sheets, and metal casing of the equipment, reducing its performance and service life, and even causing electrical failures. Therefore, a new type of distribution cabinet is urgently needed to address these issues. Utility Model Content

It not only has temperature and humidity detection functions, but can also actively dissipate heat from the distribution cabinet and remove moisture from the air inside the distribution cabinet to ensure the normal operation of electrical equipment in the distribution cabinet.

[0010] Furthermore, the dehumidification module is connected to the active heat dissipation module, and the gas discharged by the heat dissipation fan in the active heat dissipation module can take away the moisture on the dehumidification material in the dehumidification module during the discharge process.

[0011] Furthermore, two partitions are symmetrically provided in the dehumidification box, and a plurality of through holes are provided on the two partitions. The two partitions divide the dehumidification box into three spaces. A dehumidification material is respectively installed in the space on the side away from each other of the two partitions, and the space between the two partitions is a through channel; the air duct is connected to the space between the two partitions in the dehumidification box.

[0012] Furthermore, the air guide duct includes a first guide duct and a second guide duct, one end of the first guide duct is fixedly connected to the air outlet of the heat dissipation fan, and the other end of the first guide duct is connected to one end of the channel between the two partitions in the dehumidification box; the other end of the space between the two partitions in the dehumidification box is connected to one end of the second guide duct, and the other end of the second guide duct extends toward the side wall adjacent to the distribution cabinet body, and is connected to the heat dissipation port on the side wall of the distribution cabinet body.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0025] like Figure 1-Figure 3 As shown, a distribution cabinet with environmental detection and adjustment functions disclosed in the present application includes a distribution cabinet body 1 with various electrical equipment installed inside, and a temperature detection module 2, a humidity detection module 3, an active heat dissipation module 4 and a dehumidification module 5 are installed in the distribution cabinet body 1; the active heat dissipation module 4 includes a heat dissipation fan 41 installed in the distribution cabinet body 1, and the air inlet end of the heat dissipation fan 41 faces the electrical equipment in the distribution cabinet body 1, and the air outlet end of the heat dissipation fan 41 extends to the outside of the distribution cabinet body 1 through the air duct 42; the dehumidification module 5 includes a dehumidification box 51, and the dehumidification box 51 is filled with dehumidification material 52. The top of the dehumidification box 51 is provided with a breathable cover 53, and the air in the distribution cabinet body 1 can contact the dehumidification material 52 through the air holes on the cover 53; the temperature detection module 2, the humidity detection module 3 and the active heat dissipation module 4 are all electrically connected to the control system in the distribution cabinet body 1.

[0026] In the above embodiment, the shell of the heat dissipation fan 41 of the present application is installed on a specific bracket in the distribution cabinet box 1 by fixing bolts, and the heat dissipation fan 41 of the present application is an axial flow exhaust fan similar to the range hood. When it is working, it can draw air in the distribution cabinet box 1 from its air inlet end, and then discharge it into the air duct 42 from its air outlet end. The air duct 42 can guide the air with a certain temperature to be discharged outside the distribution cabinet box 1, thereby realizing active heat dissipation of the internal environment of the distribution cabinet box 1. Compared with the method of using natural ventilation to dissipate heat through air exchange holes in the prior art, the present application uses the heat dissipation fan 41 The active heat dissipation method has obviously stronger heat dissipation capacity and can cope with more scenarios. For example, when the external ambient temperature is high, the temperature difference between the temperature inside the distribution cabinet box 1 and the external environment is small, which will cause the exchange rate between the air in the distribution cabinet box 1 and the air in the external environment to decrease, and the heat in the distribution cabinet box 1 is difficult to be discharged efficiently; and the heat dissipation fan 41 of the present application can provide power for the air in the distribution cabinet box 1 after working, so that it actively flows outward, and thus even when the temperature difference between the external ambient temperature and the temperature inside the distribution cabinet box 1 is small, it can also have a good heat dissipation effect on the internal environment of the distribution cabinet box 1.

[0027] The temperature detection module 2, humidity detection module 3 and active heat dissipation module 4 of the present application are all electrically connected to the control system in the distribution cabinet box 1, so that the temperature detection module 2 and humidity detection module 3 can transmit the temperature and humidity data of the environment in the distribution cabinet box 1 measured in real time to the control system, and the control system with data analysis and processing capabilities (this control system is a prior art and will not be described in detail here) can issue corresponding instructions based on the corresponding temperature and humidity values. For example, when the temperature detection module 2 detects that the temperature in the distribution cabinet box 1 is low and will not affect the operation of the internal power equipment, the control system can put the heat dissipation fan 41 into a shutdown state; when the temperature in the distribution cabinet box 1 detected by the temperature detection module 2 is too high and will affect the normal operation of the internal power equipment, the control system can start the heat dissipation fan 41 to work and actively cool the inside of the distribution cabinet box 1; when the temperature in the distribution cabinet box 1 drops, the control system can stop the heat dissipation fan 41 again. This can avoid the heat dissipation fan 41 from continuing to work and affecting its service life.

[0028] In addition, the dehumidification material 52 filled in the dehumidification box 51 installed in the distribution cabinet body 1 can absorb the moisture (or water in the air) in the distribution cabinet body 1, thereby dehumidifying the air in the distribution cabinet body 1 to ensure that the components of the power equipment in the distribution cabinet body 1 always work in dry air. This can avoid affecting the normal use of components such as power equipment when the air humidity in the distribution cabinet body 1 is too high due to the influence of the external environment. The humidity detection module 3 can detect the humidity of the environment in the distribution cabinet body 1 in real time. When the humidity of the environment in the distribution cabinet body 1 is higher than the standard value, the control system of the distribution cabinet body 1 electrically connected to the humidity detection module 3 can promptly alarm through a buzzer or remotely transmit the humidity abnormality signal to the technicians in the monitoring room, so that the technicians can find it in time, go to the site to check the dehumidification material 52 and other materials in the distribution cabinet body 1, and take corresponding measures.

[0029] Furthermore, if Figure 2 and Figure 3 As shown, the dehumidification module 5 is connected to the active heat dissipation module 4 , and the gas discharged by the heat dissipation fan 41 in the active heat dissipation module 4 can take away the moisture on the dehumidification material 52 in the dehumidification module 5 during the discharge process.

[0030] In the above embodiments, the active heat dissipation module 4 of the present application mainly functions to discharge the heat in the distribution cabinet box 1 to the external environment. During the heat dissipation process, gas flow can be generated in the distribution cabinet box 1. The dehumidification material 52 in the dehumidification module 5 needs to restore its dehumidification capacity after adsorbing moisture, so it is necessary to remove the collected moisture. Generally, the common means of removing this part of water is to heat or accelerate the surrounding air flow rate. The present application connects the active heat dissipation module 4 with the dehumidification module 5, which can just utilize the hot air flow generated by the heat dissipation fan 41 in the active heat dissipation module 4 when dissipating heat, to take away part of the moisture on the dehumidification material 52, thereby extending the service life of the dehumidification material 52. In this way, the dehumidification material 52 can continue to work for a long time even if it is not replaced after being placed in the distribution cabinet box 1.

[0031] Furthermore, if Figure 3 As shown, two partitions 6 are symmetrically arranged in the dehumidification box 51, and multiple through holes 7 are provided on the two partitions 6. The two partitions 6 divide the dehumidification box 51 into three spaces. A dehumidification material 52 is respectively installed in the space on the side away from each other of the two partitions 6, and the space between the two partitions 6 is a through channel; the air duct 42 is connected to the space between the two partitions 6 in the dehumidification box 51.

[0032] In the above embodiment, for ease of understanding, the two spaces on the sides of the two partitions 6 in the dehumidification box 51 of the present application, which are located away from each other, are referred to as the first space and the second space, respectively. The through passage between the two partitions 6, which is not provided with the dehumidifying material 52, is referred to as the third space. The dehumidifying material 52 placed in the first and second spaces can be connected to the space within the distribution cabinet body 1 through the ventilation holes in the cover plate 53. In this way, moisture in the environment within the distribution cabinet body 1 can be removed by the dehumidifying material 52 in the first and second spaces, thereby ensuring that the humidity within the distribution cabinet body 1 remains within a normal range.

[0033] The third space is connected to the air duct 42, so that the hot air extracted by the heat dissipation fan 41 will flow through the third space through the air duct 42 when discharged outward, and the two partitions 6 in the width direction of the third space are provided with through holes 7. Because the third space is connected to the first space and the second space, when the hot air flows through the third space, it can carry away part of the moisture on the dehumidification material 52 through the through holes 7 on the partition 6 (after the dehumidification material 52 absorbs the moisture in the distribution cabinet box 1, the moisture content on the dehumidification material 52 will be reduced). The water content of the air in the distribution cabinet box 1 is greater than the water content in the air, and the airflow in contact with the dehumidification material 52 is hot air. According to the principle of water evaporation, gases with high temperature, high wind speed and low humidity can increase the evaporation of water. The hot air discharged by the heat dissipation fan 41 in this application meets the above conditions. Therefore, after the hot air contacts the dehumidification material 52, part of the moisture on the dehumidification material 52 will migrate to the hot air and leave the distribution cabinet box 1 with the hot air), so that the dehumidification material 52 continues to have a good dehumidification ability in the distribution cabinet box 1.

[0034] Since the present application effectively utilizes the heat emitted by the electrical equipment in the distribution cabinet box 1 to restore the dehumidification material 52, compared with the method of relying on the natural evaporation of water in the dehumidification material 52 to restore when the air is dry, the present application greatly improves the recovery efficiency of the dehumidification material 52; compared with the subsequent method of restoring the dehumidification capacity of the dehumidification material 52 through special heating equipment, the present application saves energy consumption.

[0035] Furthermore, if Figure 2 and Figure 3 As shown, the air guide duct 42 includes a first guide duct 421 and a second guide duct 422. One end of the first guide duct 421 is fixedly connected to the air outlet of the heat dissipation fan 41, and the other end of the first guide duct 421 is connected to one end of the channel between the two partitions 6 in the dehumidification box 51; the other end of the space between the two partitions 6 in the dehumidification box 51 is connected to one end of the second guide duct 422, and the other end of the second guide duct 422 extends toward the side wall adjacent to the distribution cabinet box 1, and is connected to the heat dissipation port on the side wall of the distribution cabinet box 1.

[0036] In the above embodiments, the heat dissipation fan 41 of the present application is arranged in a position close to multiple power equipment in the distribution cabinet box 1 in order to conveniently and quickly absorb the heat around the power equipment. The dehumidification box 51 is arranged on the bottom plate of the distribution cabinet box 1 for easy installation and fixation. Therefore, there is a certain distance between the heat dissipation fan 41 and the dehumidification box 51. The first guide pipe 421 of the present application can guide the hot air discharged from the air outlet of the heat dissipation fan 41 into the third space in the dehumidification box 51. After the hot air passes through the third space and flows through the second guide pipe 422 to the special heat dissipation port for ventilation on the distribution cabinet box 1, the hot air and part of the moisture on the dehumidification material 52 are discharged to the external environment through the heat dissipation port.

[0037] Furthermore, if Figure 2 As shown, the air holes on the cover plate 53 are only provided in the areas corresponding to the two dehumidification materials 52 .

[0038] In the above embodiments, the cover plate 53 of the present application is set in the above manner, which not only ensures that the air in the distribution cabinet box 1 can smoothly pass through the air vents on the cover plate 53 and contact the dehumidification material 52 in the dehumidification box 51 and be adsorbed by the dehumidification material 52, but also ensures that the channel in the dehumidification box 51 for passing hot air will not leak part of the hot air from the top.

[0039] Furthermore, the temperature detection module 2 is a T-type thermocouple, which is installed on the back panel of the power distribution cabinet body 1 .

[0040] In the above embodiments, the temperature measuring device commonly used to detect the temperature of liquid or gas is a thermocouple temperature sensor, referred to as a thermocouple. It can directly measure the temperature and convert the temperature signal into a thermoelectromotive force signal, which is then converted into the temperature of the measured medium through an electrical instrument. It has the characteristics of high performance temperature, large temperature measurement range, and signal transmission over long distances, and it has a simple structure and is easy to use. In actual use, the thermocouple can be further divided into K-type thermocouple, J-type thermocouple, E-type thermocouple, N-type thermocouple and T-type thermocouple. Although the temperature measurement range of the T-type thermocouple is not as good as that of other types of thermocouples, since the temperature of the environment inside the distribution cabinet box 1 is generally not too high, the use of the T-type thermocouple is sufficient to meet the measurement requirements of the internal environment temperature of the distribution cabinet box 1 during use, and it can also effectively save costs.

[0041] Furthermore, the humidity detection module 3 is a resistive humidity sensor, which is mounted on the back panel of the power distribution cabinet body 1 .

[0042] In the above embodiments, the resistive humidity sensor is a sensor that measures humidity by using the principle that the electrical properties (such as resistance) of the humidity-sensitive element change with humidity. It not only has high measurement accuracy and fast response speed, but also is low cost.

[0043] Furthermore, the dehumidification material 52 is a diatomaceous earth moisture absorbing plate.

[0044] In the above embodiments, diatomaceous earth is a natural organic material whose main raw material is diatoms. It has a unique microporous structure and rich active minerals. The number of pores in a single volume of diatomaceous earth is approximately 5000-6000 times that of a single volume of activated carbon. Therefore, it can efficiently absorb moisture in the air in the distribution cabinet box 1 and release the moisture in a timely manner for recycling.

[0045] The implementation principle of this embodiment is: when the distribution cabinet body 1 is in use, the temperature detection module 2 and the humidity detection module 3 can detect the temperature and humidity of the internal environment of the distribution cabinet body 1 in real time. The temperature increase may affect the operation of the power equipment. The heat dissipation fan 41 in the active heat dissipation module 4 will start and discharge the hot air in the distribution cabinet body 1 to the external environment through the air duct 42. When the temperature of the environment inside the distribution cabinet body 1 is normal, the heat dissipation fan 41 will stop working.

[0046] In addition, in order to ensure the normal humidity in the distribution cabinet box 1, the dehumidification material 52 in the dehumidification module 5 will adsorb the moisture in the environment inside the distribution cabinet box 1 in real time, thereby ensuring the dryness of the environment inside the distribution cabinet box 1 and avoiding problems with related components in the distribution cabinet box 1 due to moisture in the air.

[0047] Since the electrical equipment in the distribution cabinet body 1 is in a state of continuous operation, and the gap between the distribution cabinet body 1 and the outside world is limited, the heat dissipation fan 41 in the distribution cabinet body 1 may often be in an operating state, so that the hot air discharged by the heat dissipation fan 41 can often pass through the dehumidification module 5 and contact the dehumidification material 52 in the dehumidification box 51, thereby taking away some of the moisture on the dehumidification material 52, so that the dehumidification material 52 in the dehumidification box 51 can continuously dehumidify the air in the distribution cabinet body 1. In actual use, if an extreme environment with low ambient temperature and high air humidity is encountered, the temperature of the electrical equipment in the distribution cabinet body 1 may be normal, but the humidity is high. At this time, the heat dissipation fan 41 can also be started, and the heat dissipation fan 41 can be used to blow flowing gas into the dehumidification module 5 to accelerate the loss of moisture on the dehumidification material 52, so that the dehumidification material 52 can quickly restore its dehumidification capacity to dehumidify the air in the distribution cabinet body 1.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
