The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:

[0026] Figure 1 A schematic diagram of the structure of a motor dehumidification device provided in an embodiment of this utility model is shown.

[0027] Figure 2 A schematic diagram of another motor dehumidification device provided in an embodiment of this utility model is shown. Detailed Implementation

[0028] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0029] This utility model embodiment provides a motor dehumidification device, such as Figure 1 As shown, it includes: a control module 11, an operation data acquisition module 12, a temperature sensor 13, a humidity sensor 14, and a dehumidification module 15.

[0030] The operation data acquisition module 12 is used to collect the motor's operation data and send it to the control module 11. The temperature sensor 13 and humidity sensor 14 are installed inside the motor windings to collect temperature and humidity data inside the motor windings and send the data to the control module 11.

[0031] In this embodiment of the invention, the motor dehumidification device can dehumidify motors of different voltage levels, such as high-voltage motors and low-voltage motors. The control module 11 achieves data acquisition and control command transmission through data communication with various sensors and the dehumidification module. The operation data acquisition module 12 is installed on the power line and includes several voltage and current sensors to collect voltage and current data during motor operation, and outputs the motor's voltage, current, load, and power consumption data to the control module 11. The dehumidification module 15 includes at least two dehumidification units of different dehumidification types. By combining dehumidification units of different types, different dehumidification needs can be met, ensuring dehumidification quality.

[0032] It's important to note that temperature is a key factor affecting dehumidification efficiency. Generally, lower temperatures cause moisture in the air to condense into water droplets, thus accelerating dehumidification. However, if the temperature is too low, the dehumidifier may malfunction due to frost buildup. Therefore, monitoring the temperature ensures that the dehumidifier operates within a suitable temperature range, preventing excessively low or high temperatures from negatively impacting dehumidification performance. By collecting temperature and humidity data from inside the motor windings, close monitoring of critical dehumidification components in the motor is possible, significantly improving the response speed of dehumidification control and thereby increasing dehumidification efficiency while ensuring dehumidification quality.

[0033] Each dehumidification unit includes at least two dehumidification components, each connected to the control module. The dehumidification components of the same dehumidification unit are distributed both inside the motor windings and inside the motor housing. In other words, each type of dehumidification unit includes two or more dehumidification components, distributed in two regions: inside the motor windings and inside the motor housing. Each region includes dehumidification components from all types of dehumidification units. By installing the dehumidification components from different dehumidification units inside the windings and inside the motor housing, the dehumidification workspace is reduced, and dehumidification efficiency is improved.

[0034] The control module is connected to different dehumidification units and controls each unit to dehumidify according to its corresponding operating frequency. The operating frequency of each dehumidification unit can be selected by the control module based on the comparison results of temperature and humidity data with corresponding thresholds or temperature and humidity ranges, as well as data representing motor load status and operating efficiency. In different dehumidification units, the operating frequency can correspond to a specific preset operating frequency value or a matching preset operating mode. The control module coordinates the control of dehumidification units of different dehumidification types, controlling the dehumidification units to perform dehumidification with different dehumidification ratios based on motor conditions, such as different load states, different operating efficiencies, different motor insulation performance, and abnormal motor operating states. By controlling different dehumidification units to dehumidify according to their corresponding operating frequencies, the adaptability of dehumidification function to application scenarios can be improved, fully utilizing the characteristics of different dehumidification types, thereby improving dehumidification effect and efficiency.

[0035] In this embodiment of the invention, temperature sensor 13 and humidity sensor 14 are installed inside the motor windings to collect temperature and humidity data within the windings. Specifically, temperature sensor 13 and humidity sensor 14 can be installed in the stator windings and / or rotor windings of the motor. Temperature is one of the key factors affecting dehumidification efficiency. Generally, the lower the temperature, the easier it is for moisture in the air to condense into water droplets, thus accelerating dehumidification. However, if the temperature is too low, the dehumidifier may fail to operate normally due to frost formation. Therefore, by monitoring the temperature, it can be ensured that the dehumidifier operates within a suitable temperature range, avoiding adverse effects of excessively low or high temperatures on the dehumidification effect. By collecting temperature and humidity data inside the motor windings, close-range monitoring of key dehumidification components of the motor can be achieved, greatly improving the response speed of dehumidification control.

[0036] The temperature sensor 13 can be a fiber optic temperature sensor, such as a thermo-scattering fiber optic temperature sensor, a Raman scattering fiber optic temperature sensor, or a fluorescent fiber optic temperature sensor. Preferably, it can be a fluorescent fiber optic temperature sensor, which acquires temperature data through fiber optic fluorescence thermometry. It has the characteristics of strong anti-electromagnetic interference capability and high measurement accuracy, and can accurately monitor the temperature changes of the motor windings.

[0037] In this embodiment of the invention, the control module 11 sends an operation control signal to the dehumidification module 15 via a wireless network or a data cable. The control module 11 also receives data collected by the operation data acquisition module 12, the temperature sensor 13, and the humidity sensor 14 via the same wireless network or data cable. The data communication between the control module and the dehumidification module and each sensor can utilize either a wireless network or a data cable, and different communication methods can be used with different modules and sensors, depending on the specific application scenario. For example, if the sensors are wireless, wireless network communication can be used. Alternatively, if the network conditions in the operating environment are poor, the dehumidification module and the control module can be connected via a data cable. This improves the applicability to dehumidification environments.

[0038] In this embodiment of the invention, the operation data acquisition module 12 includes a current sensor, a voltage sensor, and a processor. The input terminal of the processor is connected to the current sensor and the voltage sensor, respectively, and the output terminal is connected to the control module 11. The processor is used to acquire current data and voltage data, and / or determine power data based on the current data and voltage data, and send at least one of the current data, the voltage data, and the power data to the control module 11. The operation data acquisition module is installed on the power line of the motor and includes a voltage sensor, a current sensor, and a processor. It is used to acquire voltage data and current data during motor operation and output the motor's voltage data, current data, and data calculated based on the current data and voltage data, such as power data, to the control module. The control module can determine the motor's load status based on the comparison between the current output by the operation data acquisition module and the motor's rated current, or the power and the motor's rated power. The motor load status and temperature and humidity data are used as the data basis for the control module to control the dehumidification module.

[0039] In this embodiment of the utility model, such as Figure 2 As shown, the dehumidification module 15 includes a condensation dehumidification unit 1501, an adsorption dehumidification unit 1502, and a heating dehumidification unit control module 1503.

[0040] The condensation dehumidification module 1501, adsorption dehumidification module 1502, and heating dehumidification module 1503 employ different dehumidification technologies and apply different dehumidification principles, resulting in significant differences in dehumidification efficiency, power consumption, and impact on ambient temperature. For example, the adsorption dehumidification unit consumes less power than the condensation dehumidification unit, while the condensation dehumidification unit has a higher dehumidification efficiency. Under certain conditions, the heating dehumidification unit provides auxiliary support to the other two types of dehumidification units. By operating these three types of dehumidification systems in tandem, they can better adapt to complex dehumidification environments, meet dehumidification requirements with varying power consumption and efficiencies, thereby improving dehumidification efficiency and applicability to multiple application scenarios.

[0041] In one example, the motor dehumidification device includes: a control module, an operation data acquisition module, a temperature sensor, a humidity sensor, and a dehumidification module. The operation data acquisition module, the temperature sensor, and the humidity sensor are respectively connected to the control module, and the dehumidification module is connected to the control module. The control module sends operation control signals to the dehumidification module via a wireless network or data cable; the control module receives data collected by the operation data acquisition module, the temperature sensor, and the humidity sensor via a wireless network or data cable.

[0043] The temperature sensor and the humidity sensor are used to collect temperature and humidity data inside the motor windings and send the data to the control module. The temperature sensor and humidity sensor are installed inside the stator windings and / or rotor windings of the motor. The temperature sensor is a fluorescent fiber optic temperature sensor.

[0044] The dehumidification module includes a condensation dehumidification unit, an adsorption dehumidification unit, and a heating dehumidification unit control module. Each dehumidification unit includes at least two dehumidification components, each connected to the control module. The dehumidification components within the same dehumidification unit are located both inside the motor windings and inside the motor housing.

[0045] The control module is used to control the dehumidification module to dehumidify the motor based on the operating data and the temperature and humidity data. Specifically, the control module is connected to different dehumidification units and is used to control each dehumidification unit to dehumidify according to its corresponding operating frequency.
