Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Technical terms in the embodiments of the present invention are explained below.
A sensor: a detection device can sense the information to be measured, and can convert the sensed information into an electric signal or other information output in a required form according to a certain rule so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like.
Temperature measuring sensor: a sensor for detecting temperature.
A temperature controller of the transformer; an apparatus for detecting transformer temperature, controlling start and stop of a fan of a transformer, and alerting of abnormal operation of the transformer.
In the related art, a temperature sensor in a temperature controller is easily damaged or failed. The temperature sensor may be subjected to vibration or collision during transportation and handling of the product, and may be subjected to mechanical force during installation of the transformer, which may cause damage to the temperature sensor. In addition, in the start-stop of the transformer and the voltage withstand test of the transformer, damage may occur between the platinum wire and silver palladium, and between the lead wire and silver palladium of the temperature sensor due to the high voltage impact sensor loop, so that the internal loop of the resistor of the temperature sensor is similar to break, and the temperature sensor is disabled. The platinum wire and silver palladium are metal materials in the detection head of the temperature sensor.
The temperature controller alarms for abnormal operation of the transformer according to the temperature measured value of one phase of the three-phase transformer, for example, a command can be generated to control the transformer to stop working. Under the condition that a corresponding temperature measuring sensor in the three-phase transformer fails, the temperature controller can judge that the temperature of the transformer is abnormal according to the measured temperature of the failed temperature measuring sensor, and then the tripping of the transformer is controlled, so that the situation that the transformer is mistakenly tripped occurs, and the normal operation of a machine room is affected.
To solve the problem, embodiments of the present invention provide a temperature control method, apparatus, electronic device, and non-transitory computer readable storage medium for a transformer.
The following describes in detail the technical solutions provided by the embodiments of the present invention with reference to fig. 1 to 6.
Fig. 1 is a flowchart of a temperature control method of a transformer according to an embodiment of the present invention. The method provided by the embodiment of the invention can be executed by any electronic device with computer processing capability, such as a terminal device and/or a server. As shown in fig. 1, a temperature control method of the transformer includes:
Specifically, the first sensor is a temperature measuring sensor for measuring the temperature of the first phase of the transformer. The temperature sensor may be a PTC (positive temperature coefficient ) thermistor sensor, for example a platinum resistor sensor. The PTC thermistor sensor has a larger resistance value as the temperature is higher. The platinum resistance in the platinum resistance sensor changes in resistance value when the temperature changes. And applying constant voltage to two ends of the platinum resistor, and detecting the current value at the current temperature to obtain the resistance value at the current temperature. And obtaining the current temperature according to the corresponding relation between the resistance value and the temperature. The first measured temperature is the current temperature of the first phase of the transformer acquired by the first sensor.
In particular, the second sensor may be the same temperature measuring sensor as the first sensor for measuring the temperature of the second phase of the transformer. The second measured temperature is the current temperature of the second phase of the transformer acquired by the second sensor.
And 106, generating a temperature alarm signal according to the first measured temperature, the second measured temperature and the set temperature threshold.
Specifically, if the current temperature exceeds the allowable temperature threshold, an abnormal operation of the transformer is indicated. Correspondingly, a temperature alarm signal needs to be generated to cope with the abnormal operation of the transformer. Here, the temperature threshold may be classified into several levels, for example, when the temperature threshold of the lowest level is exceeded, the fan of the transformer needs to be controlled to be turned on, and when the temperature threshold of the highest level is exceeded, the transformer needs to be controlled to be stopped. Here, controlling the fan on of the transformer includes controlling the number of on-times of a plurality of fans that cool down the transformer.
In the embodiment of the invention, the two-phase temperature data of the transformer are collected, and the temperature alarm signal is generated according to the comparison between the two-phase temperature data and the set threshold value, so that the transformer is controlled to stop running when necessary, the safety of equipment in a machine room can be protected, the temperature alarm is carried out according to the one-phase temperature data of the transformer after the comparison, the false jump of the transformer can be prevented, and the normal running of the machine room is ensured.
In the related art, the average service life of the temperature controller is 5 years, and the failure modes of the temperature controller include power-on unlit, abnormal display, overtemperature alarm and overtemperature Wen Tiaozha output failure. The average service life of the platinum resistor in the temperature measuring sensor is 5 years, and the failure mode of the platinum resistor has unstable resistance, large deviation of precision and short circuit.
The scenes of accelerating the aging or the service life reduction of the temperature measuring sensor are as follows: in the voltage withstand test of the transformer, the sensor probe does not take a protective measure, so that the sensor probe is broken down by high voltage to fail; when the transformer is switched on, the starting voltage is impacted, so that the probe of the temperature measuring sensor is broken down by high voltage to fail.
In the embodiment of the invention, the temperature control of the transformer is changed from single-phase control to double-phase control, so that the fault jump event of the transformer caused by the failure of the temperature measuring sensor can be avoided.
The computer program for executing the steps of the temperature control method of the transformer according to the embodiment of the present invention may be written into a control chip of the temperature controller, and the control chip may be a single chip microcomputer, and is not limited thereto.
In a newly built machine room, or in the process of modifying an existing machine room, the sensor plug can be separated from the temperature control box, and the computer program is written into the temperature controller. The temperature control box is a container for accommodating the temperature controller, and a socket connected with the temperature controller is arranged on the shell of the temperature control box and can be connected with the sensor plug in an adaptive manner.
After the computer program is written into the temperature controller, two temperature measuring sensors for testing can be used for being connected with temperature control, the environment temperature where the two temperature measuring sensors for testing are positioned is changed, the control state of the temperature controller for controlling the transformer is observed, and the set logic can be ensured to be put into operation after normal operation.
Fig. 2 shows a connection relationship between a transformer and a temperature controller in an embodiment of the present invention. As shown in fig. 2, the temperature controller 201 is connected to two temperature measuring sensors disposed on two phases of the three phases U, V, W of the transformer, so as to receive two measured temperatures obtained by measuring the two phase temperatures of the transformer by the temperature measuring sensors, and performs logic judgment according to the two measured temperatures and the temperature threshold value, so as to determine whether the transformer needs to be controlled to stop running.
In one embodiment of the present invention, the temperature threshold includes a first threshold and a second threshold, and in step 106, a temperature alarm signal is generated if the first measured temperature is greater than the set first threshold and the second measured temperature is greater than the set second threshold. Here, the first threshold value and the second threshold value may be equal or unequal.
If one of the first measured temperature and the second measured temperature is normal and the other measured temperature is abnormal, the temperature controller does not generate a temperature alarm signal. At the moment, the temperature measuring sensor defaulted to be used for measuring temperature abnormality fails, so that the judgment of the temperature controller on the temperature of the transformer is not affected, the situation of false tripping of the transformer is not caused, and the normal operation of the transformer is ensured.
For example, if the first threshold is 151 ℃, the second threshold is 150 ℃, the first measured temperature is 190 ℃, and the second measured temperature is 70 ℃, the temperature controller does not generate a temperature alarm signal, and the transformer operates normally. It can be understood that: if one phase reaches 190 ℃, the other phases can exceed 150 ℃ under the operation condition, so that the transformer can not be influenced to exceed Wen Tiaozha under the operation condition, and the normal operation of the transformer can be judged. And if the first measured temperature is 155 ℃ and the second measured temperature is 152 ℃, the temperature controller generates a temperature alarm signal to control the transformer to stop running.
In addition, the temperature threshold may further include a third threshold, for example, the third threshold may be set to 70 ℃, only one fan needs to be turned on when the temperature of the transformer is less than 70 ℃, and if the temperatures of two phases of the transformer are both greater than 70 ℃, the temperature controller may generate corresponding fan control signals to turn on two or more fans. Under the condition that the power of the fan can be adjusted, only the fan is required to run at low power when the temperature of the transformer is lower than 70 ℃, and if the temperatures of two phases of the transformer are both higher than 70 ℃, the temperature controller can generate corresponding fan control signals so that the fan runs at high power.
In the embodiment of the present invention, the judgment logic of the temperature controller may further be: and generating a temperature alarm signal when the average value of the temperatures of the first measured temperature and the second measured temperature is larger than a set temperature threshold value.
Here, the set temperature threshold may be a fourth threshold, for example, the fourth threshold may be 115 ℃, and if the first measured temperature is 150 ℃, and the second measured temperature is 70 ℃, the average value of the first measured temperature and the second measured temperature is 110 ℃, and at this time, the temperature controller does not generate the temperature alarm signal. If the first measured temperature is 150 ℃, the second measured temperature is 90 ℃, the average value of the first measured temperature and the second measured temperature is 120 ℃, and at the moment, the temperature controller generates a temperature alarm signal.
The logic judgment of temperature control is carried out by collecting the temperature data of two phases in the three-phase transformer, which is equivalent to adopting a redundancy mechanism, and the tripping of the transformer is controlled only when the temperature data of two phases are abnormal. The situation that the transformer jumps mistakenly when temperature judgment is carried out only according to single-phase temperature data in the three-phase transformer can be avoided, and normal operation of a machine room is guaranteed. Here, two phases in the three-phase transformer are fixed two phases, i.e. a first phase and a second phase of the transformer are selected. For example, a logical judgment of temperature control based on temperature data of the U-phase and V-phase of the transformer may be selected.
The temperature control is carried out by collecting the temperature data of the appointed two phases in the three-phase transformer, and compared with the temperature control according to the temperature data of one phase in the three-phase transformer, the probability of damage of the two-phase sensor is smaller, so that the probability of false tripping of the transformer is smaller, and the stable operation of a machine room is facilitated.
In the embodiment of the invention, the three-phase temperature data of the transformer can be acquired, and the logic judgment of temperature control can be performed according to the temperature data of any two phases in the three-phase temperature data. For example, after the temperature data of the U, V and W phases of the transformer are collected, the U-phase and the V-phase may be selected to perform logic determination of temperature control, the U-phase and the W-phase may be selected to perform logic determination of temperature control, and the V-phase and the W-phase may be selected to perform logic determination of temperature control.
In the logic determination of temperature control based on the temperature data of any two phases of the three-phase temperature data, as shown in fig. 3, another temperature control method of the transformer includes:
In particular, the third sensor may be the same temperature measuring sensor as the first sensor for measuring the temperature of the third phase of the transformer. The third measured temperature is the current temperature of a third phase of the transformer acquired by the third sensor.
The temperature sensor is a vulnerable component. Once the sensor is put into operation, there is a risk of a power outage in the event of a replacement of the sensor again. The temperature data of any two phases in the three-phase transformer is detected, so that the transformer can be judged to be unnecessary to stop running when one phase of the transformer fails and the other phase is normal, and the transformer can be ensured to work continuously on the premise of not replacing the temperature measuring sensor.
In one embodiment of the present invention, the temperature threshold includes a first threshold and a second threshold, and in the logic determination in step 106, if any one of the measured temperatures according to the first measured temperature, the second measured temperature, and the third measured temperature is greater than the set first threshold, and the other measured temperature is greater than the set second threshold, a temperature alarm signal is generated. Here, the first threshold value and the second threshold value may be equal or unequal.
For example, if the first threshold is 152 ℃, the second threshold is 151 ℃, the first measured temperature is 90 ℃, the second measured temperature is 70 ℃, and the third measured temperature is 160 ℃, the temperature controller does not generate a temperature alarm signal, and the transformer operates normally. If the first measured temperature is 155 ℃, the second measured temperature is 80 ℃, and the third measured temperature is 160 ℃, the temperature controller generates a temperature alarm signal to control the transformer to stop running.
Wherein, a corresponding temperature threshold value can be set for each of the first measured temperature, the second measured temperature and the third measured temperature. The logic determination of step 106 may further be: only when any two of the three measured temperatures meet the condition that the two measured temperatures are larger than the corresponding temperature threshold values, the temperature controller is triggered to generate a temperature alarm signal, so that the temperature controller generates the temperature alarm signal to control the transformer to stop running.
In addition, the logic determination in step 106 may be: and generating a temperature alarm signal when the average value of any two measured temperatures among the first measured temperature, the second measured temperature and the third measured temperature is larger than a set temperature threshold value.
Here, the temperature alarm signal may be generated only when the maximum measured temperature among the first measured temperature, the second measured temperature, and the third measured temperature is set to be smaller than the average value of the three measured temperatures. The trip condition of the temperature controller of the scheme is severe, for example, the three-phase temperature reaches 150 ℃, and the temperature controller still cannot trip.
Meanwhile, three-phase temperature data in the three-phase transformer are collected, and temperature control is carried out according to random or appointed two-phase temperature data, which is equivalent to temperature control by adopting a further redundancy mechanism, so that the measurement data of a temperature measurement sensor can be fully utilized, the false jump of the transformer is avoided, and the stable operation of a machine room is facilitated.
According to the temperature control method for the transformer, provided by the embodiment of the invention, the temperature of the transformer is monitored according to the temperatures of two phases in the three-phase transformer, so that the transformer can be controlled to trip when the temperature of the transformer is abnormal, and compared with the prior art, the false tripping caused by the occurrence of faults of a corresponding temperature measuring sensor of the transformer can be prevented, and the normal operation of a machine room is ensured.
