[0002] When a motor runs in a humid environment for a long time, it may cause many problems. For example, the performance of the insulation material inside the motor may be reduced, increasing the risk of motor failure; the metal parts inside the motor are prone to corrosion and oxidation in a humid environment, affecting the service life of the motor; excessive humidity may cause short circuits or leakage in the circuit inside the motor, posing a threat to the safe operation of the motor, etc. Therefore, motor dehumidification is an important measure to ensure the safe and stable operation of the motor.

[0003] Existing motor dehumidification mainly uses a resistance heater or other heating source to heat the motor as a whole to achieve the effect of humidifying the motor environment. However, due to the slow heating speed of the heating source, the dehumidification response is not timely, and the dehumidification effect is poor, resulting in low motor dehumidification efficiency.

[0078] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0079] To solve the problem of low motor dehumidification efficiency, the present invention provides a motor dehumidification method, such as Figure 1 As shown, the method includes:

[0080] 101. Obtain the temperature, humidity and operation data of the motor.

[0081] In an embodiment of the present invention, the motor is dehumidified based on the motor dehumidification device. The motor can be a motor of different voltage levels, such as a high-voltage motor and a low-voltage motor. The motor dehumidification device includes a control module, an operation data acquisition module, a temperature sensor, a humidity sensor, and a dehumidification module. The dehumidification module includes at least two dehumidification units with different dehumidification modes, and the dehumidification mode may include condensation dehumidification, adsorption dehumidification, heating dehumidification, etc. The control module is the current execution subject, and the control module realizes data collection and transmission of control instructions by communicating data with each sensor and dehumidification unit (through a data line or a wireless network). The data communication between the control module and the dehumidification module and each sensor specifically adopts wireless network communication or data line communication, and the communication between different modules and sensors can also adopt different communication methods, which can be determined according to the needs of the specific application scenario. For example, if the sensor is a wireless sensor, wireless network communication can be used. For another example, if the network status of the use environment is not good, the dehumidification module and the control module can be connected using a data line. The operation data acquisition module is installed on the power supply line of the motor, including a voltage sensor, a current sensor and a processor, which is used to collect voltage data and current data during the operation of the motor, 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.

[0082] It should be noted that the temperature sensor and humidity sensor are installed inside the winding of the motor to collect the temperature and humidity data inside the winding, that is, the temperature and humidity data are collected based on the temperature sensor and humidity sensor installed inside the motor winding. Among them, the temperature sensor and humidity sensor can be specifically installed inside the stator winding and / or rotor winding of the motor winding. The number of temperature sensors and humidity sensors can be multiple. The temperature sensor can use an optical fiber temperature sensor, which collects temperature data through optical fiber fluorescence temperature measurement technology, has the characteristics of strong anti-electromagnetic interference ability and high measurement accuracy, and can accurately monitor the temperature change of the motor winding. Temperature is one of the key factors affecting the dehumidification effect. Generally, the lower the temperature, the easier it is for the moisture in the air to condense into water droplets, thereby accelerating the dehumidification speed. However, if the temperature is too low, the dehumidifier may not be able to operate normally due to frost. Therefore, by monitoring the temperature, it can be ensured that the dehumidifier works within a suitable temperature range to avoid too low or too high temperature from having an adverse effect on the dehumidification effect. By collecting the temperature and humidity data inside the motor winding, close monitoring of the key dehumidification components of the motor can be achieved, greatly improving the response speed of the dehumidification control.

[0083] 102. Determine an expected dehumidification level based on the temperature and humidity data, and determine a load state of the motor based on the operation data.

[0084] In an embodiment of the present invention, the intensity of dehumidification required for the current environment, that is, the expected dehumidification level, is determined according to the temperature data and humidity data in the temperature and humidity data. Specifically, it can be determined by matching the corresponding relationship between the lower limit values ​​of different temperature and humidity ranges and the dehumidification intensity coefficient or the number of levels established in advance. It can also be determined by comparing different humidity and temperature thresholds with the current temperature and humidity data. For example, if the current temperature and humidity data is greater than the first temperature and humidity threshold, it is a first-level dehumidification; if it is less than the first temperature and humidity threshold and greater than the second temperature and humidity threshold, it is a second-level dehumidification; if it is less than the second temperature and humidity threshold, it is a third-level dehumidification. Among them, the humidity represented by the first temperature and humidity threshold and the second temperature and humidity threshold decreases in sequence. The dehumidification intensity of the first, second, and third levels of dehumidification decreases in sequence. The load state can be determined according to the comparison result of the current output by the operation data acquisition module and the rated current of the motor, or the power and the rated power of the motor. It can be divided into multiple load levels, for example, the load data is greater than the rated load for heavy load; the load data is less than the rated load, and is greater than 40% of the rated load for medium load; the load data is less than 40% of the rated load for light load. The division method of the load level can be customized according to the actual application requirements, and the embodiment of the present invention does not make specific limitations.

[0085] 103. Determine the operating frequencies of different dehumidification units in the dehumidification module according to the load state, the expected dehumidification level and the coordinated operation strategy.

[0086] In an embodiment of the present invention, different dehumidification units respectively include at least two dehumidification components for performing dehumidification operations, and the dehumidification components are respectively distributed inside the motor winding and inside the motor housing. That is to say, each dehumidification unit of a dehumidification type includes two or more dehumidification components, which are distributed in two areas, the motor winding and the motor housing, and each area includes dehumidification components of all dehumidification types. The dehumidification process is realized by the coordinated operation of dehumidification units based on different dehumidification methods. When the dehumidification unit includes more than two, if any of the units fails, dehumidification can also be achieved by other units in coordination. The current execution subject determines the operating frequencies of different types of dehumidification units according to the load state and the expected dehumidification level. Specifically, the total dehumidification intensity can be determined according to the expected dehumidification level, and the output ratio of different types of dehumidification units can be determined according to the dehumidification speed requirement and equipment energy consumption corresponding to the load state, and then the operating frequency of different dehumidification units is determined. In different dehumidification units, the operating frequency can correspond to a specific preset operating frequency value, or it can correspond to a matching preset operating mode.

[0087] It should be noted that different dehumidification units use different dehumidification technologies and are based on different dehumidification principles, which have great differences in dehumidification efficiency, power consumption and impact on ambient temperature. By operating dehumidification units of different dehumidification types together and working together, it is possible to adapt to complex dehumidification environments to a greater extent and meet dehumidification requirements of different power consumption and efficiency, thereby improving dehumidification efficiency and the applicability of dehumidification to multiple application scenarios. In addition, by installing the dehumidification unit inside the winding and the motor casing, the dehumidification action space can be reduced and the dehumidification efficiency can be improved.

[0088] 104. Control different dehumidification units in the dehumidification module to operate at their respective corresponding operating frequencies to collaboratively dehumidify the motor.

[0089] In an embodiment of the present invention, after determining the operating frequencies of different dehumidification units, the current execution subject issues operation control instructions to the corresponding dehumidification units according to the corresponding operating frequencies, so as to control each dehumidification unit to operate according to the corresponding operating frequencies, thereby realizing the coordinated dehumidification operation of multiple dehumidification types. By controlling the different dehumidification units to dehumidify according to their respective corresponding operating frequencies, the adaptability of the dehumidification function to the application scenario can be improved, and the characteristics of different dehumidification types can be fully utilized, thereby improving the dehumidification effect and efficiency. In addition, by quickly responding to changes in the temperature and humidity of the motor, the precise humidity of the motor can be measured, thereby improving the efficiency of dehumidification.

[0090] In an embodiment of the present invention, for further explanation and limitation, as Figure 2 As shown, the step of determining the operating frequencies of different dehumidification units in the dehumidification module according to the load state, the expected dehumidification level and the coordinated operation strategy includes:

[0091] 201. Identify, from a collaborative operation parameter mapping relationship set, a collaborative proportion and a total dehumidification output that match the expected dehumidification level.

[0092] 202. When the load state is medium load, configure the operating frequencies of the condensing dehumidification unit, the adsorption dehumidification unit and the heating dehumidification unit respectively according to the synergistic specific gravity and the total dehumidification output;

[0093] 203. When the load state is light load or heavy load, the synergy ratio is adjusted according to the load-sensing dehumidification strategy, and the operating frequencies of the condensing dehumidification unit, the adsorption dehumidification unit and the heating dehumidification unit are configured according to the adjusted synergy ratio and the total dehumidification output.

[0094] In an embodiment of the present invention, the dehumidification module includes a condensation dehumidification unit, an adsorption dehumidification unit and a heating dehumidification unit. The collaborative operation parameter mapping relationship set includes the relationship between different expected dehumidification levels and their corresponding collaborative weights and total dehumidification output. Among them, the collaborative weight is used to characterize the output weight ratio of the condensation dehumidification unit, the adsorption dehumidification unit and the heating dehumidification unit. The total dehumidification output is used to characterize the total dehumidification capacity of each dehumidification unit, which can be the dehumidification amount per unit time, the dehumidification intensity, etc. For example, the first dehumidification level corresponds to the maximum total dehumidification output, the second dehumidification level corresponds to 70% of the maximum total dehumidification output, the third dehumidification level corresponds to 40% of the maximum total dehumidification output, and so on. The collaborative weights corresponding to different dehumidification levels can be the same. For example, the collaborative weights of different dehumidification levels are all 1:1:1, that is, the outputs of the three modules are the same. It can also be different. For example, in the collaborative weight corresponding to the high dehumidification level, the weight of the condensation dehumidification unit is greater than that of the other two modules, and in the collaborative weight corresponding to the low dehumidification level, the weight of the adsorption dehumidification unit is the largest, and the weight of the hotter dehumidification unit is the smallest. The specific value of the synergistic weight can be customized according to actual needs, and the embodiments of the present invention do not make specific limitations. The load state of the motor is divided into heavy load, medium load and light load. Heavy load indicates that the motor is in a state of high load operation, light load indicates that the motor is in a state of low load operation, and medium load indicates that the motor is in a state of normalized load operation. Under medium load, the operating frequency of different dehumidification units can be adjusted without combining with the load state. Under heavy load and light load conditions, it is necessary to adjust the synergistic weight of different dehumidification units according to the dehumidification demand characteristics under the two states, so as to integrate the motor load state factor in the process of configuring the operating frequency of different dehumidification units, improve the accuracy of the output distribution of different dehumidification units, and improve the applicability of the dehumidification process to the application environment.

[0095] In one embodiment of the present invention, for further explanation and limitation, the step of adjusting the synergistic proportion according to the load sensing dehumidification strategy when the load state is light load or heavy load includes:

[0096] When the load state is light load, determining a first correction coefficient according to the level of the light load;

[0097] According to the first correction coefficient, the weight of the adsorption dehumidification unit is positively corrected, and the weight of the condensation dehumidification unit and / or the heating dehumidification unit is negatively corrected to obtain an adjusted synergistic ratio;

[0098] When the load state is heavy load, determining a second correction coefficient according to the level of the heavy load;

[0099] The weight of the condensing and dehumidifying unit is positively corrected according to the second correction coefficient, and the weight of the heating and dehumidifying unit is negatively corrected to obtain an adjusted synergistic ratio.

[0100] In the embodiment of the present invention, the positive correction is to increase the specific gravity, and the negative correction is to reduce the specific gravity. When the motor is in a light load state, the heat dissipation is less, the ambient temperature inside the motor is low, and the insulation performance is high. At this time, the motor has a high tolerance to humidity. In addition, compared with the high temperature environment inside the motor with high load, the low temperature environment inside the motor is not easy to cause a large temperature difference between the inside and outside of the motor, and it will also reduce the degree of moisture absorption of the motor. Therefore, when the motor is lightly loaded, the efficiency requirement for dehumidification is relatively low. An adsorption dehumidification unit with lower dehumidification power consumption and second best dehumidification efficiency can be selected as the main dehumidification unit, and its weight in the synergistic specific gravity is increased, and the weight of any one of the condensation dehumidification unit and the heating dehumidification unit is reduced, or the weight of the condensation dehumidification unit and the heating dehumidification unit is reduced simultaneously. Among them, light load can include light loads of different levels. The smaller the load represented by the light load level, the larger the corresponding correction coefficient. The specific correspondence between the correction coefficient and the light load level can be customized according to actual application requirements, and the embodiment of the present invention does not make specific limitations. It should be noted that the weights of the condensing dehumidification unit and the heating dehumidification unit can be corrected to zero, that is, only some of the moisture absorption modules are enabled, thereby maximizing energy savings.

[0101] When the motor is overloaded, a large amount of heat will be generated. The ambient temperature inside the motor is high, and the insulation performance decreases with the increase of temperature, resulting in a low tolerance of the motor to humidity. In addition, the internal high temperature environment caused by the high load of the motor increases the temperature difference between the inside and outside of the motor, which increases the moisture absorption of the motor. Therefore, when the motor is overloaded, the efficiency of dehumidification is required to be higher. A condensation dehumidification unit with the best dehumidification efficiency and the second best low power consumption can be selected as the main dehumidification unit, and its weight in the synergistic weight can be increased, and the weight of the heating dehumidification unit can be reduced to avoid the secondary high temperature generated by the heating dehumidification unit. The weight of the adsorption dehumidification unit can be left unchanged or adjusted, and can be customized according to specific application requirements, which is not specifically limited in the embodiment of the present invention. Among them, heavy load can include different levels of heavy load, and the greater the load represented by the heavy load level, the greater the corresponding correction coefficient. The specific correspondence between the correction coefficient and the heavy load level can be customized according to actual application requirements, which is not specifically limited in the embodiment of the present invention.

[0102] In one embodiment of the present invention, for further explanation and limitation, the step of configuring the operating frequencies of the condensing dehumidification unit, the adsorption dehumidification unit, and the heating dehumidification unit according to the synergistic specific gravity and the total dehumidification output when the load state is medium load includes:

[0103] Calculating the operating efficiency of the motor according to the operating data, and determining a third correction coefficient according to the operating efficiency difference value when the operating efficiency is less than a preset efficiency threshold;

[0104] According to the third correction coefficient, the weight of the adsorption dehumidification unit is positively corrected, and the weight of the heating dehumidification unit is negatively corrected to obtain an adjusted synergistic ratio;

[0105] The operating frequencies of the condensing dehumidification unit, the adsorption dehumidification unit and the heating dehumidification unit are respectively configured according to the adjusted synergistic specific gravity.

[0106] In an embodiment of the present invention, as the use time of the motor increases and the motor ages, the operating efficiency of the motor continues to decrease, and more power consumption is not ultimately converted into mechanical energy, but is dissipated in the form of heat energy, thereby affecting the moisture absorption and insulation effect of the motor. Therefore, the level of motor operating efficiency will also affect the demand for dehumidification. The operating data may include rated power and actual power, and the operating efficiency of the motor can be calculated based on the rated power and actual power. When the operating efficiency is less than the preset efficiency threshold, it indicates that the motor has a large amount of power consumption loss, and it is necessary to determine the amplitude of the correction of the weight of each module based on the difference between the current operating efficiency and the preset efficiency threshold (operating efficiency difference value). The larger the difference value, the larger the corresponding third correction coefficient. The correction logic and method for different modules are the same as the correction logic of the load-sensing dehumidification strategy, which will not be repeated here.

[0107] In one embodiment of the present invention, for further explanation and limitation, before determining the expected dehumidification level according to the temperature and humidity data in step 1, the method further includes:

[0108] Acquiring historical electrical data of the motor within a first preset time period;

[0109] Calculating insulation performance parameters of the motor based on the historical electrical data;

[0110] When the insulation performance parameter is less than a preset insulation performance threshold, determining a humidity correction coefficient according to a difference between the insulation performance parameter and the preset insulation performance threshold;

[0111] A negative correction is performed on each of the temperature and humidity data ranges in the dehumidification level mapping relationship set according to the humidity correction coefficient to reduce the lower limit value of the humidity range corresponding to the expected dehumidification level.

[0112] In the embodiment of the present invention, the dehumidification level mapping relationship set includes a mapping relationship between different dehumidification levels and their corresponding temperature and humidity data ranges. Due to the different insulation performance of different motors, their tolerance to humidity is also different. The insulation performance of the same motor is also changing as the equipment ages. Therefore, under the same temperature and humidity environment, motors with different insulation performances have different requirements for dehumidification. The worse the insulation performance of the motor, the worse the tolerance to humidity, and the higher the demand for dehumidification. The insulation performance parameters of the motor are calculated according to the electrical data of the motor, and the difference (difference value) between the insulation performance parameters and the preset insulation performance threshold is determined to determine how much the lower limit of the humidity range needs to be corrected (humidity correction coefficient). Among them, the larger the difference value, the larger the humidity correction coefficient, that is, the smaller the insulation performance parameter is than the preset insulation performance threshold, the worse the insulation of the motor, and the smaller the lower limit of the humidity range corresponding to the dehumidification level, which is equivalent to the humidity judgment standard for meeting the same dehumidification level. For example, a motor with a larger insulation performance parameter needs to reach a humidity of 80% before it can be determined as a first-level dehumidification; a motor with a smaller insulation performance parameter can be determined as a first-level dehumidification when the humidity reaches 70%. Among them, the preset insulation performance threshold can be set based on the average value of the insulation performance parameters of all motors at the standard temperature. The humidity correction coefficient can be a humidity percentage. The humidity correction coefficient is subtracted from the lower limit and upper limit of the humidity range to achieve negative correction of the temperature and humidity data range, and the temperature range can remain unchanged. The first preset time period can be one month, three months, etc., and the embodiment of the present invention does not make specific limitations.

[0113] In one embodiment of the present invention, for further explanation and limitation, after the step of controlling different dehumidification units in the dehumidification module to operate according to their respective corresponding operating frequencies, the method further includes:

[0114] Obtaining historical temperature and humidity data within a second preset time period;

[0115] Performing curve fitting processing based on the historical temperature and humidity data to obtain temperature and humidity prediction data;

[0116] When the difference between the temperature and humidity prediction data and the temperature and humidity data is greater than the temperature and humidity change threshold, the operating frequencies of the condensation dehumidification unit, the adsorption dehumidification unit and the heating dehumidification unit are correspondingly increased according to a preset frequency increase ratio.

[0117] In an embodiment of the present invention, the temperature and humidity data at future moments are predicted by curve fitting to prevent sudden changes in temperature and humidity, which may result in untimely dehumidification response. The temperature and humidity change threshold is a threshold for determining whether the temperature and humidity have suddenly changed, and may be set based on historical experience. When it is determined that the temperature and humidity will suddenly change, the operating frequencies of the condensation dehumidification unit, the adsorption dehumidification unit, and the heating dehumidification unit are increased synchronously according to the preset frequency increase ratio. Among them, the preset frequency increase ratio may be the same minimum operating frequency adjustment ratio, or may include operating frequency increase ratios corresponding to different dehumidification units, which need to be determined according to the specifications of the core components used by the dehumidification unit. The second preset duration is a historical period forward from the current moment, which may be 30 minutes, 1 hour, etc. The fitting process of the temperature and humidity data may be curve fitting for the temperature data and the humidity data separately, or may be weighted summed and then curve fitting may be performed as a whole. The curve fitting method may be the least squares method, the linear regression method, or other curve fitting methods. By predicting the temperature and humidity data, it is possible to determine the humidity change trend inside the motor, adjust the operating frequency of the dehumidification unit in advance, and prevent sudden humidity changes from causing serious impact on the motor.

[0118] In one embodiment of the present invention, for further explanation and limitation, the method further includes:

[0119] Monitoring the motor operation status according to the operation data;

[0120] When the running state of the motor is detected to be abnormal, abnormal motor running warning information is generated, and the abnormal motor running warning information is sent to the remote monitoring terminal;

[0121] sending a stop operation instruction to the heating dehumidification unit, and recalculating the operation frequencies of the adsorption dehumidification unit and the condensation dehumidification unit respectively according to the above;

[0122] The adsorption dehumidification unit and the condensation dehumidification unit are controlled to perform cooperative dehumidification according to the updated operation frequency.

[0123] In an embodiment of the present invention, the dehumidification device is equipped with a collection module for collecting operation data. In addition to providing data support for the adjustment of the dehumidification scheme, it can also monitor the operating status of the motor. If the operating status of the motor is abnormal, such as voltage fluctuation, abnormal increase in current, etc., an early warning message can be sent to the remote monitoring terminal. Among them, the operating data includes at least one of current data, voltage data, and power data. The abnormal operation of the motor is usually a high-temperature state. At this time, the heating dehumidification unit is stopped to avoid more heat generation. At the same time, while maintaining the current dehumidification capacity, the operating frequencies of the adsorption dehumidification unit and the condensation dehumidification unit are redistributed and controlled. By timely warning of possible faults in the motor and controlling the dehumidification unit, downtime and maintenance costs can be reduced, thereby minimizing motor damage in abnormal conditions.
