Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and particularly relates to a transformer temperature monitoring device with an alarm function. Background Technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. Among them, the temperature monitoring of the transformer is a key measure to ensure the normal operation of the transformer and extend its service life.

[0003] In the temperature monitoring device of the existing technology transformer, the temperature sensor and the controller are directly installed inside the transformer box body, which is rather troublesome during maintenance.

[0004] The Chinese patent with the publication number CN216361651U was proposed in the prior art to solve the above-mentioned existing technical problems. The technical solution disclosed in this patent document is as follows: A transformer temperature detection device that is convenient for maintenance, including a transformer cover plate. An installation pipe is movably penetrated through the surface of the transformer cover plate. A threaded connection pipe is fixedly connected to the top of the installation pipe. A threaded cover is threadedly connected to the outside of the threaded connection pipe. A detection structure is fixedly connected to the inner top of the threaded cover. A connecting plate is fixedly installed on the left side of the installation pipe. A fixing rod is fixedly installed on the upper surface of the transformer cover plate. The fixing rod movably penetrates through the connecting plate. A through hole is opened on the front surface of the installation pipe. An inspection structure is arranged inside the through hole. A chute is opened on the upper surface of the transformer cover plate. An adjusting structure is slidably installed inside the chute. The utility model can quickly perform an external inspection on the temperature detection device and is convenient for maintenance and replacement. However, there will still be a problem that if the temperature sensor is damaged, it cannot trigger an alarm in time after the internal temperature of the transformer rises abnormally, making it impossible for the staff to cool down the transformer in time, which has certain limitations. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a transformer temperature monitoring device with an alarm function to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A transformer temperature monitoring device with an alarm function includes a transformer main body and radiators; a number of radiators are fixedly installed at both ends of the transformer main body, one side of the transformer main body is fixedly connected with a protective cover, a rubber hose is fixedly installed inside the protective cover, one side of the protective cover is attached to a movable plate, and the movable plate is attached to the surface of one side of the rubber hose. Adjusting components are provided on the other side of the movable plate at the top and bottom of the protective cover, and the adjusting components are used to install and adjust the movable plate. A temperature sensor is fixedly installed on one side of the transformer main body, and the temperature sensor is located at the bottom of the movable plate. A controller is provided at the bottom of the temperature sensor, and an alarm component is provided at the top of the movable plate, and the alarm component is used for alarm work.

[0008] By installing a temperature sensor, the temperature inside the transformer main body can be monitored. When the temperature sensor monitors that the temperature inside the transformer main body reaches a certain standard, the monitoring result is transmitted to the controller, and the controller then controls the alarm to start alarming to warn the user. During the process of the temperature inside the transformer main body rising continuously, the rubber hose expands due to heat. At the same time, the protective cover can block all the surfaces of the rubber hose except one side, so that the rubber hose can only expand to one side, thereby squeezing the movable plate to one side, making the push block approach the control switch. When the temperature inside the transformer main body reaches a certain standard, the push block can press the control switch, thereby triggering the alarm to warn the user, which can avoid the failure of the temperature sensor and affect the alarm effect, thus improving the effect of monitoring the temperature of the transformer main body.

[0009] A further improvement of the technical solution of the present utility model lies in that: the alarm component includes a fixed frame, the fixed frame is located at the top of the movable plate and is fixedly connected with one side of the transformer main body, an alarm is fixedly installed at the top of the fixed frame, the fixed frame extends to one side of the movable plate and is fixedly installed with a control switch, and a push block is fixedly installed on one side of the movable plate, and the push block corresponds to the control switch.

[0010] Adopting the above technical solution, in this solution, when the temperature inside the transformer main body reaches a certain standard, the push block can press the control switch, thereby triggering the alarm to warn the user.

[0011] A further improvement of the technical solution of the present utility model lies in that: a reinforcing block is fixedly installed at the top of the fixed frame, and the reinforcing block is fixedly connected with the surface of one side of the transformer main body.

[0012] Adopting the above technical solution, in this solution, by installing the reinforcing block, the contact area between the fixed frame and the transformer main body can be enlarged, thereby playing a role in strengthening the fixed frame.

[0013] A further improvement of the technical solution of the present utility model lies in that: the adjusting component includes a number of connecting frames, each connecting frame is fixedly connected to the surface on the other side of the movable plate, a fixed block is slidably installed inside each connecting frame, a spring is fixedly installed on one side of each fixed block, and each spring is fixedly connected to the side wall near one side inside the connecting frame respectively.

[0014] With the above technical solution, in this solution, when the temperature inside the transformer body continuously drops, the rubber hose can shrink and rebound, and at the same time, the elastic force of the spring itself can pull the movable plate to the other side, so that the push block is separated from the control switch, and at this time, the alarm can be automatically turned off.

[0015] A further improvement of the technical solution of the present utility model lies in that: a cavity is provided inside the rubber hose, and there is oxygen in the cavity.

[0016] With the above technical solution, in this solution, by supplying oxygen into the air provided inside the rubber hose, when the rubber hose is heated, the oxygen can expand due to heat, thereby increasing the expanding volume of the rubber hose.

[0017] A further improvement of the technical solution of the present utility model lies in that: a heat conducting sheet is fixedly installed inside the protective cover, the heat conducting sheet is attached to the surface on one side of the transformer body, and the other surface of the heat conducting sheet is fixedly connected to the rubber hose.

[0018] With the above technical solution, in this solution, at the same time, by installing the heat conducting sheet, the heat inside the transformer body can be quickly guided to the surface of the rubber hose, thereby increasing the force of extrusion on the push block and further ensuring that the push block can press the control switch.

[0019] A further improvement of the technical solution of the present utility model lies in that: an installation plate is fixedly installed on the other side of the controller, one side of the installation plate is fixedly connected to a heat insulation plate, and the heat insulation plate is fixedly connected to the surface on one side of the transformer body.

[0020] With the above technical solution, in this solution, by installing the heat insulation plate, the installation plate can be separated from the transformer body, avoiding the influence on the controller due to the too high temperature inside the transformer body, thus playing a protective effect on the controller.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0022] 1. The present utility model provides a transformer temperature monitoring device with an alarm function. When the temperature inside the transformer body continuously rises, the rubber hose can be heated and continuously expand, squeezing the movable plate and the push block to one side. When the temperature inside the transformer body reaches a certain standard, the push block can press the control switch and trigger the alarm to warn the user, avoiding the failure of the temperature sensor and affecting the alarm effect, thereby improving the effect of transformer temperature monitoring.

[0023] 2. The present utility model provides a transformer temperature monitoring device with an alarm function. By supplying oxygen into the air inside the rubber hose, the oxygen can expand after being heated, thereby increasing the expanding volume of the rubber hose.

A temperature sensor 8 is fixedly installed on one side of the transformer main body 1, and the temperature sensor 8 is located at the bottom of the movable plate 2.

The alarm component 6 includes a fixing frame 601, the fixing frame 601 is located at the top of the movable plate 2 and is fixedly connected to one side of the transformer main body 1, an alarm 603 is fixedly installed at the top of the fixing frame 601, the fixing frame 601 extends to one side of the movable plate 2 and a control switch 602 is fixedly installed, a push block 201 is fixedly installed on one side of the movable plate 2, and the push block 201 corresponds to the control switch 602.

[0034] In this embodiment, by installing the temperature sensor 8, the temperature inside the transformer main body 1 can be monitored. When the temperature sensor 8 monitors that the temperature inside the transformer main body 1 reaches a certain standard, the monitoring result is transmitted to the controller 4, and the controller 4 controls the alarm 603 to start alarming to warn the user; during the process of the temperature inside the transformer main body 1 continuously rising, the rubber hose 7 expands due to heat. At the same time, the protective cover 3 can block all the surfaces of the rubber hose 7 except one side, so that the rubber hose 7 can only expand to one side, thereby being able to squeeze the movable plate 2 to one side, making the push block 201 approach the control switch 602. When the temperature inside the transformer main body 1 reaches a certain standard, the push block 201 can press the control switch 602, thereby triggering the alarm 603 to warn the user, which can avoid the failure of the temperature sensor 8 and affect the alarm effect, thus improving the effect of temperature monitoring of the transformer main body 1; when the temperature inside the transformer main body 1 continuously drops, the rubber hose 7 can contract and rebound, and at the same time, through the elastic force of the spring 503 itself, the movable plate 2 can be pulled to the other side, so that the push block 201 is separated from the control switch 602, and at this time, the alarm 603 can be automatically turned off.

[0035] As Figure 1 and Figure 3 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a cavity is formed inside the rubber hose 7, and there is oxygen in this cavity. A heat conducting sheet 301 is fixedly installed inside the protective cover 3. The heat conducting sheet 301 is attached to the surface of one side of the transformer main body 1, and the surface of the other side of the heat conducting sheet 301 is fixedly connected to the rubber hose 7.

[0036] In this embodiment, by supplying oxygen into the air in the rubber hose 7, when the rubber hose 7 is heated, the oxygen can expand due to heat, thereby increasing the expansion volume of the rubber hose 7. At the same time, by installing the heat conducting sheet 301, the heat inside the transformer main body 1 can be quickly guided to the surface of the rubber hose 7, thereby expanding the force for squeezing the push block 201 and further ensuring that the push block 201 can press the control switch 602.

[0037] As Figure 1 、 Figure 2 and Figure 4 shown, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, an installation plate 401 is fixedly installed on the other side of the controller 4, and a heat insulation plate 402 is fixedly connected to one side of the installation plate 401. The heat insulation plate 402 is fixedly connected to the surface of one side of the transformer main body 1.

[0038] In this embodiment, by installing the heat insulation plate 402, the mounting plate 401 can be separated from the transformer body 1, preventing the temperature inside the transformer body 1 from being too high and affecting the controller 4, thus achieving a protective effect on the controller 4.

[0039] Next, the working principle of the transformer temperature monitoring device with an alarm function will be specifically described.

[0040] As Figures 1 - 6 shown, when the transformer body 1 is in use, the temperature inside the transformer body 1 will rise. At this time, the temperature sensor 8 is used to monitor the temperature inside the transformer body 1. When the temperature sensor 8 detects that the temperature inside the transformer body 1 reaches a certain standard, the monitoring result is transmitted to the controller 4, and the controller 4 controls the alarm 603 to start alarming. During the process of the temperature inside the transformer body 1 rising continuously, the heat conducting sheet 301 quickly guides the heat inside the transformer body 1 to the surface of the rubber hose 7, causing the rubber hose 7 to expand continuously due to heat. At the same time, the oxygen inside the rubber hose 7 can also expand due to heat, further increasing the expanded volume of the rubber hose 7 and squeezing the movable plate 2 and the push block 201 to one side. When the temperature inside the transformer body 1 reaches a certain standard, the push block 201 can press the control switch 602, thereby triggering the alarm 603 to warn the user. After the temperature inside the transformer body 1 drops, the rubber hose 7 can contract and rebound, and at the same time, the spring 503 is used to pull the movable plate 2 to the other side, separating the push block 201 from the control switch 602, so that the alarm 603 is automatically turned off.

[0041] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
