Technical Field

[0001] The utility model relates to the technical field of transformer oil level monitoring, in particular to a transformer oil level monitoring device. Background Art

[0002] When an oil-immersed transformer is in use, there is transformer oil inside it. The transformer oil can dissipate heat and cool the transformer during operation, and insulate and maintain the windings inside the transformer, so that it remains in a good insulation state. In order to ensure the normal use of the transformer, the amount of transformer oil must be tested.

[0003] When using traditional monitoring equipment, an oil level gauge is often installed on the outer wall of the transformer. The inspectors observe the reading of the oil level gauge to detect the liquid level of the transformer oil. However, due to the limitations of manual inspections by inspectors, the liquid level of the transformer oil cannot be monitored in real time, and thus the lack of transformer oil cannot be discovered in time, which affects the normal heat dissipation and operation of the transformer, and then causes the transformer to malfunction. Utility Model Content

[0010] As a preferred technical solution of the present invention: a distance scale is installed on the outer wall of the scale, a signal transmitter is installed on the top of the top plate, and the signal transmitter is electrically connected to the indicator light.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The transformer oil level monitoring device uses a monitoring chamber set on the outer wall of the monitoring tube. The oil height inside the transformer body is equal to the height inside the monitoring tube. When the float rises and falls with the height of the liquid level, the rolling wheel on the float will trigger the trigger plate in the corresponding interval, thereby realizing the monitoring of the oil height. Once it is lower than the normal height range, timely feedback can be provided through background data, or when conducting on-site observation, the indicator light can be observed to light red, thereby realizing real-time monitoring of the oil height.

[0013] 2. The transformer oil level monitoring device uses a scale set on the inner wall of the monitoring chamber and a monitoring chamber made of tempered glass. The position of the indicator plate can be observed through the outer wall of the monitoring chamber. When the oil level is low and needs to be refilled, the sealing plug can be removed and transformer oil can be added to the monitoring tube and the inside of the transformer body. Remote monitoring and on-site monitoring can be achieved, thereby better ensuring that there is no shortage of transformer oil inside the transformer and ensuring the normal operation of the equipment.

[0024] By setting a monitoring tube 3 on the outer wall of the transformer body 2, and the inner cavity of the monitoring tube 3 being in communication with the inner cavity of the transformer body 2, since the inner cavities of the transformer body 2 and the monitoring tube 3 are in communication, the liquid level of the oil in the inner cavity of the transformer body 2 is equal to the liquid level in the inner cavity of the monitoring tube 3, and the buoyancy generated by the oil on the float 9 will cause the float 9 to float on the top of the liquid surface. At this time, the liquid level of the oil in the inner cavity of the transformer body 2 can be monitored according to the position of the float 9 in the inner cavity of the monitoring tube 3.

[0025] In a preferred embodiment, the inner cavity of the indicator plate 11 is movably sleeved on the outer wall of the scale 5 , and the monitoring chamber 4 is made of tempered glass.

[0026] By means of the indicator plate 11 provided on the outer wall of the float 9 and the scale 5 provided in the inner cavity of the monitoring chamber 4, when the float 9 floats on the top of the oil, the height of the float 9 will be indicated by the indicator plate 11 and displayed on the outer wall of the scale 5. At this time, the position of the indicator plate 11 on the outer wall of the scale 5 can be observed through the monitoring chamber 4 to read the height of the oil level.

[0027] In a preferred embodiment, the outer wall of the scroll wheel 10 contacts the outer wall of the touch panel 6 , and the controller 13 is electrically connected to the indicator light 12 and the touch panel 6 .

[0028] By setting the touch panel 6 on the inner wall of the monitoring chamber 4 and the scroll wheel 10 on the outer wall of the float 9, when the float 9 floats up and down along the outer wall of the limit rod 8 with the oil, the scroll wheel 10 will contact the touch panel 6 of the corresponding height, thereby triggering the touch panel 6 of the corresponding height, and then judging the position of the float 9 according to the touch panel 6 of the corresponding height, thereby realizing the monitoring of the oil height.

[0029] In a preferred embodiment, the length of the touch panel 6 is 10 cm, there are five touch panels 6 , and the five touch panels 6 are respectively installed on the inner wall of the monitoring chamber 4 .

[0030] By installing multiple touch panels 6 on the inner wall of the monitoring chamber 4, and each touch panel 6 has a height of 10CM, when the scroll wheel 10 on the outer wall of the float 9 touches the touch panel 6, the touch panel 6 at the corresponding position can indicate the height range of the float 9, and mark the position of the float 9 from the bottom of the monitoring chamber 4 upwards.

[0031] In a preferred embodiment, a distance scale is installed on the outer wall of the scale 5 , a signal transmitter is installed on the top of the top plate 7 , and the signal transmitter is electrically connected to the indicator light 12 .

[0032] By setting the scale 5 on the inner wall of the monitoring chamber 4, when the float 9 floats up and down along the outer wall of the limit rod 8, the position of the indicator plate 11 also floats up and down on the outer wall of the scale 5, so that when the user observes on site, he can accurately observe the position of the float 9 through the monitoring chamber 4, thereby obtaining the height value of the liquid level in the inner cavity of the transformer body 2.

[0033] Working principle: During the use of the above-mentioned device, when the transformer body 2 is in normal use, since the inner cavities of the transformer body 2 and the monitoring tube 3 are connected, the liquid level in the inner cavity of the transformer body 2 is equal to the liquid level in the inner cavity of the monitoring tube 3. At this time, there will be oil in the inner cavity of the monitoring tube 3, and the buoyancy generated by the oil will cause the float 9 to float on the top of the liquid surface. At this time, the scroll wheel 10 on the outer wall of the float 9 will contact the touch panel 6 at the corresponding height, and then receive the electrical signal generated by the touch panel 6 at the corresponding position under the action of the controller 13, so as to determine the position height range of the float 9, and send a signal to the signal transmitter under the action of the controller 13, and then the signal transmitter The device transmits the information to the remote background upward, and the height range of the liquid level can be remotely monitored at this time. Once the liquid level range is lower than the normal height range, or the two touch panels 6 below the inner cavity of the monitoring chamber 4 are triggered, the indicator light 12 will be lit under the action of the controller 13, so that the indicator light 12 lights up red, thereby reminding the staff to deal with it in time. When the transformer body 2 is inspected on site, if the indicator light 12 is not lit, the staff can observe the position of the indicator plate 11 through the monitoring chamber 4. By only observing the height of the indicator plate 11 on the outer wall of the scale 5, the height of the oil in the inner cavity of the transformer body 2 can be accurately known, thereby better monitoring the oil height.
