Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1, the embodiment provides an automatic temperature tester for a 10kV oil-immersed power transformer, which includes a mobile terminal 1, a temperature sensor 2, a warning device 3, a GSM communication module 4 and a control device 5. The mobile terminal 1 is used for the operation and maintenance personnel to carry. The temperature sensor 2 is located inside the 10kV oil-immersed power transformer 11 and used for detecting the oil temperature of transformer oil. The warning device 3 is fixed outside the 10kV oil-immersed power transformer 11. The control device 5 is respectively electrically connected with the temperature sensor 2, the warning device 3 and the GSM communication module 4 and is used for receiving the temperature data collected by the temperature sensor 2, controlling the warning device 3 to send out sound and/or light warning information and controlling the GSM communication module 4 to send warning messages to the mobile terminal 1.
Specifically, the temperature sensor 2 transmits the oil temperature data to the control device 5, and when the oil temperature is too high, the control device 5 immediately controls the warning information to send out sound and/or light warning information and controls the GSM communication module 4 to send a warning short message to the mobile terminal 1. The sound and/or light warning information can inform passers-by or power station personnel near the 10kV oil-immersed power transformer 11 that the oil temperature is abnormal in real time, so that relevant operation and maintenance personnel can be arranged in time to properly handle the oil temperature. The warning short message can remotely inform the operation and maintenance personnel in charge of the area, and the operation and maintenance personnel can acquire the abnormal oil temperature information at any place at any time.
Optionally, the automatic temperature tester for the 10kV oil-immersed power transformer further comprises a server 6, and the server 6 is in communication connection with the control device 5 through a 4G communication technology and is used for storing oil temperature data.
Specifically, the stored oil temperature data can be used for conveniently analyzing the oil temperature data at idle time, and further judging fault reasons and predicting working conditions of the 10kV oil-immersed power transformer 11.
Optionally, the automatic temperature tester for the 10kV oil-immersed power transformer further includes a timer 7, and the timer 7 is electrically connected to the GSM communication module 4 through the control device 5, and is configured to calculate a time interval of sending the warning short message by the GSM communication module 4.
Specifically, in order to avoid sending the warning information too frequently, the operation and maintenance personnel may be informed of the warning information by sending a warning short message once at intervals. For example, the timer 7 calculates the sending time interval of the GSM communication module 4, and the control device 5 controls the GSM communication module 4 to send an alert short message to the mobile terminal 1 every 5 min.
Optionally, the automatic temperature tester for the 10kV oil-immersed power transformer further includes a counter 8, and the counter 8 is electrically connected to the GSM communication module 4 through the control device 5, and is configured to calculate the total number of times that the GSM communication module 4 sends the warning short message.
Specifically, in order to avoid the GSM communication module 4 from transmitting the warning short message endlessly, a counter 8 may be added to count the number of times of transmitting the warning short message, for example, when the number of times of transmitting the warning short message reaches three times, the transmitting function of the GSM communication module 4 is stopped, and the warning short message is no longer transmitted to the mobile terminal 1.
Optionally, the automatic temperature tester for the 10kV oil-immersed power transformer further includes a refreshing module 9, and the refreshing module 9 is electrically connected to the GSM communication module 4 through the control device 5, and is configured to recover the signaling function of the GSM communication module 4.
Specifically, when the temperature sensor 2 detects that the oil temperature of the transformer oil is recovered to normal, it indicates that the fault has been processed, and the sending function of the GSM communication module 4 should be recovered to ensure that the warning short message can still be sent to the mobile terminal 1 when the oil temperature is abnormal next time.
It is understood that, when the temperature sensor 2 detects that the temperature of the transformer oil returns to normal, the control device 5 should stop the warning device 3 from sending the warning message.
Optionally, the warning device 3 includes a buzzer and a warning light.
Specifically, the buzzer can send out harsh sound warning information, and the warning lamp can send out dazzling light warning information, so that passersby or operation and maintenance personnel near the 10kV oil-immersed power transformer 11 can find out the oil temperature abnormity in time and properly handle the oil temperature abnormity.
Preferably, the temperature sensor 2 is a platinum resistor.
Specifically, the platinum resistor has high temperature measurement precision and can meet the high precision requirement.
Referring to fig. 2, the automatic temperature tester for the 10kV oil-immersed power transformer provided in this embodiment further includes an electric control box 10, the electric control box 10 is fixed outside the 10kV oil-immersed power transformer 11, and the control device 5 is located inside the electric control box 10.
Specifically, the buzzer may be disposed in the electrical cabinet 10, and a sound hole is formed on the electrical cabinet 10. The warning light may be fixed outside the electrical cabinet 10 to facilitate the sending of the light warning information. The GSM communication module 4 can be fixed in the electric control box 10 along with the control device 5 so as to avoid wind and rain erosion.
Preferably, the mobile terminal 1 is a mobile phone or a five-prevention machine.
Particularly, the mobile phone is convenient for operation and maintenance personnel to carry. It should be noted that the five-prevention machine is a common device for operation and maintenance personnel, and can be carried with the five-prevention machine during working.
