Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The application scene of the application is explained at first, the application is applied to the cooling protection scene of the oil-immersed transformer, and under the scene, the transformer is in a high-voltage current environment for a long time, so that the temperature rise of the transformer is easily caused, safety accidents are caused, and the temperature of the transformer needs to be controlled. The existing transformer cooling mode is mainly characterized in that a cooler is started and stopped according to temperature and load through a transformer air cooling control cabinet, the temperature of the transformer in operation is higher than the main transformer ventilation protection time-delay action on a corresponding constant value or power generation and transformation group protection device, the cooler group in an auxiliary state is started in a time-delay mode in succession, and when the oil temperature is reduced to the corresponding constant value or the main transformer ventilation protection of the power generation and transformation group protection device returns, the cooler group in the auxiliary state quits the operation.
However, the inventor finds that the existing transformer cooling mode has many problems, for example, the cooling mode of the transformer does not consider external environmental factors, for example, in the winter, the fan cooling mode has little influence on the temperature control of the transformer; for another example, the main transformer side current of the transformer is not considered, which may cause abnormal actions of the cooling protection of the transformer; for another example, if the temperature of the transformer is at a critical threshold for starting and cooling, frequent start and stop of the cooler are easily caused, and the service life of the cooler is affected. Therefore, the safe operation of the transformer cannot be ensured, and the resource waste is caused.
In order to solve the above problems, the present application provides a method, an apparatus, a storage medium, and an electronic device for controlling a temperature of a transformer, wherein the method includes obtaining an ambient temperature of a location of the transformer and specifying parameters of the transformer; determining a cooling mode according to the environment temperature; under the condition that the designated transformer parameter is greater than or equal to the preset parameter threshold value, the transformer is cooled according to the cooling mode and the first preset time threshold value, so that the cooling mode and the cooling time of the transformer are determined according to the environment temperature where the transformer is located and the designated transformer parameter, and cooling is performed in a delayed manner, the fault probability of a transformer cooler group is favorably reduced, the service life of the cooler group is prolonged, the cooling protection reliability of the transformer is improved, and the safe and stable operation of the transformer is ensured.
The present disclosure is illustrated below with reference to specific examples.
Fig. 1 is a flowchart of a method for controlling a temperature of a transformer according to an embodiment of the present disclosure, and as shown in fig. 1, the method includes:
s101, obtaining the environment temperature of the position of the transformer and specifying transformer parameters.
Wherein the specified transformer parameter may include a transformer temperature or a high side current. The temperature of the transformer can be obtained through an external temperature sensor of the transformer, or appropriate measurement parameters are selected according to the type of the transformer, and if the transformer is an oil-immersed transformer, the temperature of the transformer can be obtained through measuring the oil temperature of the transformer. The high-voltage side current of the transformer is difficult to directly measure due to high current and voltage, and can be obtained through devices such as a current inductor.
And S102, determining a cooling mode according to the environment temperature.
The transformer is used as an oil-immersed transformer as an example, and can be cooled through an oil pump and a fan. Considering that there is no obvious effect of cooling through the fan under the condition that the environment temperature of the transformer is low, the cooling mode can be determined through the environment temperature of the transformer, for example, the cooling mode can be cooled through the oil pump and the fan together under the high-temperature environment, and the cooling mode can be cooled through the oil pump only under the low-temperature environment.
For example, the preset cooling mode of the transformer includes cooling by an oil pump and a fan, and cooling by the oil pump, and determining to cool by the oil pump and the fan when the ambient temperature is greater than a preset temperature threshold; and determining to reduce the temperature through the oil pump under the condition that the ambient temperature is less than or equal to a preset temperature threshold value. Therefore, the cooling mode is determined through the ambient temperature, and the energy utilization efficiency is improved.
S103, cooling the transformer according to the cooling mode and a first preset time length threshold value under the condition that the designated transformer parameter is larger than or equal to a preset parameter threshold value.
The first preset time length threshold represents a time delay time length threshold for cooling the transformer, timing is carried out under the condition that the specified transformer parameter is greater than or equal to the preset parameter threshold, and the transformer is cooled under the condition that the timing time length is greater than or equal to the first preset time length threshold. The time delay cooling of the transformer can be realized by arranging a time relay on a cooler group or a related control device, setting a first preset time threshold value through the time relay, triggering time delay after the time relay receives a cooling instruction, and stopping time delay when the timing time reaches the first preset time threshold value.
For example, the specified transformer parameter may include a transformer temperature or a high-side current, and the first cooling-down timing is performed when the transformer temperature is greater than or equal to a first preset cooling-down threshold value or the high-side current is greater than or equal to a preset current threshold value; and under the condition that the time length of the first cooling timing is greater than or equal to the first preset time length threshold value, cooling the transformer according to the cooling mode. Therefore, through time delay cooling, frequent starting of the cooler group caused by the fact that the temperature of the transformer is at the critical threshold value of cooling can be avoided, the service life of the cooler group is prolonged, the cooling protection reliability of the transformer is improved, and safe and stable operation of the transformer is guaranteed.
By adopting the method, the environmental temperature of the position of the transformer and the specified transformer parameter are obtained; determining a cooling mode according to the environment temperature; under the condition that the designated transformer parameter is greater than or equal to the preset parameter threshold value, the transformer is cooled according to the cooling mode and the first preset long time threshold value, so that the cooling mode and the cooling time of the transformer are determined according to the environment temperature where the transformer is located and the designated transformer parameter, and cooling is performed in a delayed manner, the failure probability of a transformer cooler group is favorably reduced, the service life of the cooler group is prolonged, the cooling protection reliability of the transformer is improved, and the safe and stable operation of the transformer is ensured.
In addition, when the designated transformer parameter is smaller than the preset parameter threshold, the temperature of the transformer needs to be stopped.
In a possible implementation manner, in order to further avoid frequent start and stop of the cooler when the temperature of the transformer is at the cooling critical value, a second preset parameter threshold for instructing to stop cooling may be set, where the second preset parameter threshold is smaller than the preset parameter threshold for instructing to start cooling, and when the specified transformer parameter is smaller than or equal to the second preset parameter threshold, the cooling of the transformer is stopped.
For example, the specified transformer parameters may include a transformer temperature and a high-side current, and since the high-side current is a stable parameter that can be directly controlled, the preset current thresholds for performing the cooling and stopping the cooling may be the same threshold. Stopping cooling when the temperature of the transformer is less than or equal to a second preset cooling threshold and the high-voltage side current is less than the preset current threshold; the second preset cooling threshold is smaller than the first preset cooling threshold.
In addition, in order to further avoid frequent start and stop of the cooler group, a command for stopping cooling can be set and executed in a delayed manner through the time relay.
For example, when the transformer temperature is less than or equal to the second preset temperature-reducing threshold and the high-voltage side current is less than the preset current threshold, performing a second temperature-reducing timing; and stopping cooling under the condition that the duration of the second cooling timing is greater than or equal to a second preset duration threshold.
Therefore, the preset parameter threshold value for starting cooling and the preset parameter threshold value for stopping cooling are respectively set, and the cooling is stopped in a delayed manner, so that frequent starting and stopping of the cooler under the condition that the temperature of the transformer is at the cooling critical value are facilitated, the fault probability of the transformer cooler group is reduced, the service life of the cooler group is prolonged, and the cooling protection reliability of the transformer is improved.
It should be noted that, in order to prevent the cooler group from malfunctioning or the transformer from malfunctioning, the warning may be performed when the cooling time of the transformer is abnormal. For example, the cooling time of the transformer may be obtained; and sending alarm information when the cooling time is greater than or equal to a third preset time threshold. Therefore, potential hazards can be found in time, and the safe operation of the voltage transformer is guaranteed.

s201, obtaining the environment temperature of the position where the transformer is located.
And S202, determining a cooling mode according to the environment temperature.
Wherein, this cooling mode includes through oil pump and fan cooling to and through the oil pump cooling. Determining to reduce the temperature through the oil pump and the fan under the condition that the environmental temperature is greater than a preset temperature threshold; and determining to reduce the temperature through the oil pump under the condition that the environment temperature is less than or equal to a preset temperature threshold value.
And S203, acquiring the specified transformer parameters of the transformer.
Wherein the specified transformer parameter may include a transformer temperature or a high side current.
And S204, cooling the transformer according to the cooling mode and a first preset time threshold value under the condition that the designated transformer parameter is greater than or equal to a preset parameter threshold value.
The first preset time threshold is used for indicating that the time delay cooling is carried out under the condition that the designated transformer parameter is greater than or equal to the preset parameter threshold.
Illustratively, a first cooling-down timing is carried out when the temperature of the transformer is greater than or equal to a first preset cooling-down threshold, or the high-voltage side current is greater than or equal to a preset current threshold; and under the condition that the time length of the first cooling timing is greater than or equal to the first preset time length threshold value, cooling the transformer according to the cooling mode.
And S205, under the condition that the designated transformer parameter is smaller than the preset parameter threshold, stopping cooling the transformer according to a second preset time length threshold.
And the second preset time length threshold is used for indicating that the temperature is delayed and stopped being reduced under the condition that the designated transformer parameter is smaller than the preset parameter threshold.
For example, in order to further avoid that the cooler group of the transformer may be frequently started or stopped, a second preset cooling threshold may be set, where the second preset cooling threshold is smaller than the first preset cooling threshold. Performing second cooling timing under the conditions that the temperature of the transformer is less than or equal to the second preset cooling threshold and the high-voltage side current is less than the preset current threshold; and stopping cooling under the condition that the duration of the second cooling timing is greater than or equal to a second preset duration threshold.
And S206, obtaining the cooling time of the transformer.
And S207, sending out alarm information under the condition that the cooling time is greater than or equal to a third preset time threshold.
By adopting the method, the cooling mode and the cooling time of the transformer are determined according to the environment temperature of the transformer and the designated transformer parameters, and the cooling is performed in a delayed manner, so that the fault probability of the transformer cooler group is favorably reduced, the service life of the cooler group is prolonged, the cooling protection reliability of the transformer is improved, and the safe and stable operation of the transformer is ensured.
