Description

Technical Field

[0001] The present application relates to the technical field of power transmission engineering, and in particular to a dehumidification device. Background Art

[0002] The CT (Current Transformer) secondary junction box is an important device in the power system. Due to poor sealing and condensation caused by temperature difference, the inside of the CT secondary junction box is prone to moisture, affecting the electrical insulation performance of the CT secondary junction box and the normal operation of the power system.

[0003] In traditional technology, a desiccant is usually placed inside the CT secondary junction box to absorb the water vapor and condensed water inside the CT secondary junction box, thereby keeping the inside of the CT secondary junction box dry. However, this method requires staff to replace the desiccant regularly. During the replacement process, new water vapor will be introduced into the CT secondary junction box, resulting in poor dehumidification effect. Summary of the invention

[0004] Based on this, it is necessary to provide a dehumidification device to address the problem that in traditional technology, when workers replace the desiccant, new water vapor will be introduced into the secondary junction box, resulting in poor dehumidification effect.

[0005] The technical solution is as follows:

At this time, the drying mechanism is turned on to dry the dehumidification medium and eliminate the water vapor in the dehumidification medium, so that the dehumidification medium returns to a dry state and ensures the subsequent dehumidification efficiency of the dehumidification medium.

[0034] The electrical equipment generally comprises an electrical box, wherein the electrical box is provided with a first vent and a second vent which are connected to each other.

[0035] Please refer to Figures 1 and 2. An embodiment of the present application provides a dehumidification device, including a ventilation mechanism 100, a dehumidification mechanism 200 and a drying mechanism 300. The ventilation mechanism 100 has a first air inlet 110 and a first air outlet 120 that are connected to each other, and the first air inlet 110 is used to communicate with the first air vent; the dehumidification mechanism 200 has a dehumidification chamber, a first inlet 211 and a first outlet 212 that are connected to each other, and a dehumidification medium is provided in the dehumidification chamber. The first inlet 211 is connected to the first air outlet 120, and the first outlet 212 is used to communicate with the second air vent; the drying mechanism 300 is connected to the dehumidification chamber and is used to dry the dehumidification medium.

[0036] The above-mentioned dehumidification device, when it is necessary to dehumidify the electrical equipment, the ventilation mechanism 100 is operated to introduce the gas containing water vapor in the electrical equipment into the dehumidification chamber through the first vent, the first air inlet 110, the first air outlet 120 and the first inlet 211 in sequence, and the dehumidification medium in the dehumidification chamber can absorb the water vapor in the gas to obtain dry gas, and the dry gas then flows back to the electrical equipment through the first outlet 212 and the second vent to circulate and dry the gas in the electrical equipment; after the ventilation mechanism 100 has been running for a long time, the dehumidification medium in the dehumidification chamber has absorbed too much water vapor, resulting in the saturation of the moisture content of the dehumidification medium and a significant reduction in the water vapor absorption capacity. At this time, the drying mechanism 300 is turned on to dry the dehumidification medium and eliminate the water vapor in the dehumidification medium, so that the dehumidification medium is restored to a dry state to ensure the subsequent dehumidification efficiency of the dehumidification medium. Compared with the traditional technology, the above-mentioned dehumidification device can dry the dehumidification medium, and the staff does not need to regularly replace the desiccant in the CT secondary junction box, thereby avoiding the introduction of new water vapor into the CT secondary junction box.

[0037] Optionally, the dehumidification medium in the above embodiment may be a common desiccant, such as a silica gel desiccant, calcium chloride or calcium sulfate desiccant, etc., which is not specifically limited here.

[0038] In some embodiments, the drying mechanism 300 can dry the dehumidification medium by heating and ventilating the dehumidification medium. For example, the drying mechanism 300 can heat the dehumidification medium outside the dehumidification chamber to remove water vapor in the dehumidification medium. For another example, the drying medium can pass hot air into the dehumidification chamber to dry the dehumidification medium. No specific limitation is made here.

[0039] In one embodiment, the ventilation mechanism 100 includes a hair dryer, in which a fan is disposed. The rotation of the fan provides a flow power for the gas in the electrical device, thereby realizing the circulation of the gas.

[0040] Furthermore, the first vent is communicated with the first air inlet 110 of the hair dryer through the first conducting pipe 410 , and the second vent is communicated with the first outlet 212 through the second conducting pipe 420 .

[0041] In one embodiment, the electrical device is a CT (Current Transformer) secondary junction box.

[0042] Please refer to Figures 1 and 2. In one embodiment, the drying mechanism 300 includes a hot air blower 310. The dehumidification mechanism 200 also has a second inlet 221 and a second outlet 222. The second inlet 221 and the second outlet 222 are both connected to the dehumidification chamber, and the hot air blower 310 is connected to the second inlet 221.

[0043] The hot air blower 310 heats the air and then introduces it into the dehumidification chamber through the second inlet 221. The heated air can take away the water vapor in the dehumidification medium, and the air with water vapor is then discharged through the second outlet 222, thereby drying the dehumidification medium in the dehumidification chamber.

[0044] Furthermore, the hot air blower 310 includes a fan and a heating element. The fan is used to provide power for the flow of air, and the heating element heats the air. The heated air is introduced into the dehumidification chamber from the second inlet 221 to dry the dehumidification medium.

[0045] In other embodiments, the hot air blower 310 may also be a wind tube with a heating function, etc., which is not specifically limited here.

[0046] Please refer to Figures 1 and 2. In one embodiment, the dehumidification mechanism 200 includes a dehumidification container 230, an air inlet pipeline 240 and an air outlet pipeline 250. The dehumidification container 230 has a dehumidification chamber. One end of the air inlet pipeline 240 is arranged in the dehumidification container 230 and is connected to the dehumidification chamber. The other end of the air inlet pipeline 240 is provided with a first inlet 211 and a second inlet 221. One end of the air outlet pipeline 250 is arranged in the dehumidification container 230 and is connected to the dehumidification chamber. The other end of the air outlet pipeline 250 is provided with a first outlet 212 and a second outlet 222.

[0047] With such arrangement, the gases introduced by the ventilation mechanism 100 and the hot air blower 310 can enter the dehumidification chamber through the air inlet pipe 240, and the gases in the dehumidification chamber can be led out to the second air vent of the electrical equipment and the external environment through the air outlet pipe 250, thereby reducing the number of pipelines, which can not only reduce the production cost of the dehumidification device, but also make the overall structure of the dehumidification device more compact.

[0048] Further, referring to FIG. 2 , both the air inlet pipe 240 and the air outlet pipe 250 are T-shaped pipes, which will not be described in detail here.

[0049] Please refer to Figures 1 and 2. In one embodiment, the dehumidification device also includes a first humidity monitoring component 261, a second humidity monitoring component 262 and a control component 270. The first humidity monitoring component 261 is arranged on the air inlet pipeline 240, and the second humidity monitoring component 262 is arranged on the air outlet pipeline 250. The first humidity monitoring component 261, the second humidity monitoring component 262, the ventilation mechanism 100 and the drying mechanism 300 are all electrically connected to the control component 270.

[0050] When the first humidity monitoring component 261 detects that the humidity of the gas passing through the air inlet pipeline 240 is higher than the set value, a signal is sent to the control component 270, and the control component 270 controls the operation of the ventilation mechanism 100 to dehumidify the interior of the electrical equipment; when the second humidity monitoring component 262 detects that the humidity of the gas passing through the air outlet pipeline 250 is higher than the set value, it indicates that the dehumidification medium in the dehumidification chamber has absorbed too much water vapor, causing the moisture content of the dehumidification medium to be saturated, and the water vapor absorption capacity is greatly reduced. At this time, the second humidity monitoring component 262 sends a signal to the control component 270, and the control component 270 controls the operation of the drying mechanism 300 to dry the dehumidification medium; the gas humidity of the air inlet pipeline 240 and the air outlet pipeline 250 are monitored respectively by the first humidity monitoring component 261 and the second humidity monitoring component 262, and then the operation of the ventilation mechanism 100 and the drying mechanism 300 are adjusted to improve the convenience of use of the dehumidification device.

[0051] Furthermore, the control component 270 can also obtain the difference between the first humidity monitoring component 261 and the second humidity monitoring component 262. When the difference between the first humidity monitoring component 261 and the second humidity monitoring component 262 is greater than the preset humidity difference, it indicates that the dehumidification medium can still absorb water vapor normally; when the difference between the first humidity monitoring component 261 and the second humidity monitoring component 262 is less than the preset humidity difference, it indicates that the water vapor absorption efficiency of the dehumidification medium becomes low. At this time, the second humidity monitoring component 262 sends a signal to the control component 270, and the control component 270 controls the drying mechanism 300 to operate and dry the dehumidification medium.

[0052] In one embodiment, the control component 270 includes an MCU (Microcontroller Unit) control chip.

[0053] In one embodiment, the first humidity monitoring component 261 and the second humidity monitoring component 262 are high-precision, high-reliability capacitive or resistive humidity sensors.

[0054] Please refer to Figures 1 and 2. In one embodiment, the hot air blower 310 has a second air inlet 311 and a second air outlet 312 which are connected to each other. The second air inlet 311 is connected to the external environment. The dehumidification device also includes a first pipeline 281, a second pipeline 282, a first valve body 283 and a second valve body 284. One end of the first pipeline 281 is connected to the second air outlet 312, and the other end of the first pipeline 281 is connected to the second inlet 221. The first valve body 283 is arranged on the first pipeline 281 and can control the medium flow of the first pipeline 281. One end of the second pipeline 282 is connected to the second outlet 222, and the other end of the second pipeline 282 is connected to the external environment. The second valve body 284 is arranged on the second pipeline 282 and can control the medium flow of the second pipeline 282.

[0055] The air from the external environment enters the hot air blower 310 through the second air inlet 311 for heating, and the heated air is discharged to the first pipeline 281 through the second air outlet 312. The first valve body 283 can control the opening and closing degree of the first pipeline 281 to control the flow rate of the heated air entering the dehumidification chamber; similarly, after the heated air dries the dehumidification medium, it is discharged to the second pipeline 282 through the second outlet 222. The second valve body 284 can control the opening and closing of the second pipeline 282 to control the discharge flow rate of the air; with such a configuration, the staff can control the drying of the dehumidification medium by the hot air blower 310 by opening and closing the first valve body 283 and the second valve body 284, and the implementation cost is low and the control effect is reliable.

[0056] Please refer to Figures 1 and 2. In one embodiment, the dehumidification device also includes a third pipeline 291, a fourth pipeline 292, a third valve body 293 and a fourth valve body 294. One end of the third pipeline 291 is connected to the first air outlet 120, and the other end of the third pipeline 291 is connected to the first inlet 211. The third valve body 293 is arranged in the third pipeline 291 and can control the medium flow of the third pipeline 291. One end of the fourth pipeline 292 is connected to the first outlet 212, and the other end of the fourth pipeline 292 is used to communicate with the second vent. The fourth valve body 294 is arranged in the fourth pipeline 292 and can control the medium flow of the fourth pipeline 292.

[0057] The ventilation mechanism 100 introduces the gas in the electrical equipment into the third pipeline 291 through the first air outlet 120, and the third valve body 293 can control the opening and closing degree of the third pipeline 291 to control whether the gas in the electrical equipment can enter the dehumidification chamber; similarly, the gas with water vapor in the electrical equipment is dehumidified by the dehumidification medium in the dehumidification chamber, and then discharged to the fourth pipeline 292 through the first outlet 212, and the fourth valve body 294 can control the opening and closing degree of the fourth pipeline 292 to control whether the dehumidified gas can flow back to the electrical equipment; with such a configuration, the staff can control the dehumidification of the gas in the electrical equipment by opening and closing the third valve body 293 and the fourth valve body 294, and the implementation cost is low and the control effect is reliable.

[0058] In one embodiment, the first valve body 283 , the second valve body 284 , the third valve body 293 and the fourth valve body 294 are all solenoid valves with good corrosion resistance and fast response speed.

[0059] Please refer to Figures 1 and 2. In one embodiment, the dehumidification device has two working modes, namely, a dehumidification mode and a drying mode. When the first humidity monitoring component 261 detects that the humidity of the gas entering the dehumidification chamber is higher than a set value, the dehumidification mode is started. At this time, the control component 270 controls the third valve body 293 and the fourth valve body 294 to open, and the ventilation mechanism 100 operates. When the second humidity monitoring component 262 detects that the humidity of the gas discharged from the dehumidification chamber is higher than a set value, the drying mode is started. At this time, the control component 270 controls the first valve body 283 and the second valve body 284 to open, and the hot air blower 310 operates.

[0060] Furthermore, when the dehumidification device is started, the control component 270 is initialized and reads the preset target humidity value and other parameters, and at the same time, self-checks each hardware to ensure normal operation. After receiving the humidity data monitored by the first humidity monitoring component 261 and the second humidity monitoring component 262, the control component 270 first determines whether the humidity of the air entering the dehumidification chamber is higher than the set value. If it is higher than the set value, the current working mode is determined. If it is in the non-dehumidification mode, the dehumidification mode is started; if it is in the dehumidification mode, the dehumidification continues. At the same time, the humidity of the air after passing through the dehumidification chamber is determined. If the humidity is still high, it indicates that the dehumidification medium may be saturated with moisture, and it is necessary to consider starting the drying mode. When the humidity reaches the target value, the relevant first valve body 283 and the second valve body 284 can be closed to stop dehumidification. During the whole process, the control component 270 continuously receives the data of the first humidity monitoring component 261 and the second humidity monitoring component 262, monitors the humidity changes in real time, and adjusts the dehumidification or drying operation according to the situation, such as adjusting the dehumidification time, drying temperature, etc., to ensure that the humidity of the electrical equipment is maintained within a suitable range and reduce the cost and workload of manual maintenance. Reduce the introduction of water vapor due to manual operation, effectively solve the problems of insulation performance degradation, metal component corrosion, short circuit failure and other problems caused by moisture in electrical equipment, improve the service life and reliability of electrical equipment, and ensure the safe and stable operation of the power system.

[0063] Furthermore, the installation cabinet 500 is also provided with a connecting hole for communicating with the external environment, so as to realize the connection between the ventilation mechanism 100 and the dehumidification mechanism 200 and the electrical equipment outside the installation cabinet 500, and the connection between the dehumidification mechanism 200 and the drying mechanism 300 and the outside air.
