Description

Technical Field

[0001] The invention belongs to the technical field of oil conservator liquid level monitoring, in particular to a digital online monitoring device for transformer oil conservator oil level. Background Art

[0002] The oil pillow of the transformer is an auxiliary oil storage container of the oil-immersed transformer. It is used to contain the transformer oil that expands and contracts due to changes in oil temperature to prevent the oil from overflowing the transformer body. At present, oil level monitoring mostly relies on manual inspections. Operation and maintenance personnel need to climb to the side of the transformer regularly and check the oil level with the naked eye through the simple glass liquid level observation window on the oil pillow. Alternatively, a connected pressure gauge is set at the bottom of the oil pillow, and the oil level is detected by the pressure of the oil level inside the oil pillow. However, this method still requires the operator to observe closely. At the same time, after a long period of use, the oil inside the oil pillow will crack and generate precipitation, which will cause the glass liquid level observation window or the connecting part of the pressure gauge to be blocked, and a false oil level phenomenon will occur, which will lead to inaccurate detection. Therefore, in order to solve the above problems, a digital online monitoring device for the oil level of the transformer oil pillow is provided. Summary of the invention

[0009] Preferably, a limiting groove is provided on the connecting rod, and a limiting block capable of sliding in the limiting groove is provided on the cross pipe.

[0010] Preferably, the adjustment assembly further comprises an elastic rod fixedly sleeved on the transmission rod and located outside the oil pillow, and the bottom end of the elastic rod is a tension spring and is fixedly connected to the oil pillow;

[0011] In the initial state, the elastic rod is kept in a vertical state by its own tension, and the fan blades are kept in a vertical state. At this time, the convex shaft is at the bending part of the V-shaped slide groove.

[0012] Preferably, a projection of the blade portion on the fan blade in the vertical direction and a projection of the transmission rod in the vertical direction form an angle;

[0013] One end of the oil pillow is also fixedly connected to two protrusions, which are arranged in symmetrical directions. When the elastic rod rotates, it can abut against one of the protrusions.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The above scheme changes with the change of the oil level inside the oil pillow through the floating block. At this time, the floating block will drive the rotating shaft to rotate through the connecting rod, thereby changing the contact position between the sliding piece and the concave surface of the arc resistor. At this time, the current after the sliding piece passes through the arc resistor will change with the change of the contact position between the sliding piece and the concave surface of the arc resistor. Then, the control circuit will convert the current signal into the height of the liquid level inside the oil pillow and transmit the data to the monitoring terminal, thereby improving the safety and accuracy of the device for monitoring the oil level of the oil pillow;

[0018] The above scheme also drives the connecting column and the piston rod to rotate through the rotation of the rotating shaft, so that the two ends of the piston rod move inside the pipe three and the pipe four respectively. At this time, the bottom ends of the pipe four and the pipe three will respectively draw the transformer oil into the pipe three or the pipe four through the bottom ends of the pipe three and the pipe four due to the suction effect of the piston rod. At this time, due to the continuous suction of the transformer oil inside the pipe three and the pipe four and the resistance to the movement of the piston rod, the sensitivity of the floating block when floating or falling is increased through the connecting column, the rotating shaft and the connecting rod, thereby ensuring the stability of the device in measuring the oil level inside the oil pillow;

[0019] The above scheme uses the wind force in windy weather to blow the blades and make the transmission rod drive the V-shaped slide groove to rotate. At the same time, due to the limit block sliding in the limit groove to limit the connecting rod, the V-shaped slide groove will force the convex shaft to slide in the V-shaped slide groove and make the connecting rod move away from the elastic rod, so that the through hole 2 and the pipe 3, through the through hole 3 and the pipe 4 are misaligned. At this time, the upper part of the pipe 3 through the through hole 2 and the cylindrical filter screen and the upper part of the pipe 4 through the through hole 3 and the cylindrical filter screen are connected. At this time, the force of the piston rod to suck the transformer oil through the pipe 3 and the pipe 4 respectively increases, thereby increasing the damping of the piston rod, thereby ensuring that the device can stably measure the oil level inside the oil pillow in windy weather;

[0020] The above scheme will also drive the movement of the bending rod through the movement of the connecting rod, so that the straight slot forces the cross bar to rotate and drives the scraper to rotate to clean the sediment outside the cylindrical filter, thereby ensuring that pipeline three and pipeline four can stably connect with the transformer oil inside the oil pillow through the cylindrical filter.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, the present invention provides a digital online monitoring device for oil level of a transformer oil pillow, comprising an oil pillow 1 and a control circuit, wherein the top and bottom of the oil pillow 1 are respectively fixedly connected with a pipe 11 and a pipe 2 13, and a dehumidifier 12 is arranged on the top of the pipe 11, and further comprising: a monitoring component 2, which is arranged inside the oil pillow 1; a damping component 3, which is installed on the monitoring component 2 and used to reduce the shaking amplitude of the monitoring component 2; an adjusting component 4, which is arranged on the damping component 3 and used to adjust the damping of the damping component 3;

[0033] The monitoring assembly 2 includes a fixed block 21 fixed to the inner wall of the oil pillow 1, one end of the fixed block 21 is movably connected to a rotating shaft 22, a connecting rod 23 is also fixed to the rotating shaft 22, one end of the connecting rod 23 extends to the outside of the fixed block 21 and is hinged to a floating block 24, an arc resistor 25 is fixed to the inside of the fixed block 21, a sliding piece 26 in contact with the concave surface of the arc resistor 25 is fixed to the rotating shaft 22, a control circuit is electrically connected to the sliding piece 26 in contact with the concave surface of the arc resistor 25 and is used to monitor the current after passing through the arc resistor 25 from the sliding piece 26, and a display 27 is also fixedly installed at the bottom of the oil pillow 1;

[0034] The floating block 24 is also provided with a plurality of through holes 241;

[0035] By adopting the above scheme, the float 24 changes with the change of the oil level inside the oil pillow 1. At this time, the float 24 will drive the rotating shaft 22 to rotate through the connecting rod 23, thereby changing the contact position between the slider 26 and the concave surface of the arc resistor 25. At this time, the current after the slider 26 passes through the arc resistor 25 will change with the change of the contact position between the slider 26 and the concave surface of the arc resistor 25. Subsequently, the control circuit will convert the current signal into the height of the liquid level inside the oil pillow 1 and transmit the data to the monitoring terminal. At the same time, the liquid level data will also be transmitted to the display 27 and displayed for the operator to observe, thereby improving the safety and accuracy of the device in monitoring the oil level of the oil pillow.

[0036] like Figure 2 , Figure 4 , Figure 5 and Figure 6-Figure 8 As shown, a base 14 is fixedly connected to the bottom of the inner cavity of the oil pillow 1; the damping assembly 3 includes a pipe 31 and a pipe 4 32 respectively fixed to the upper and lower parts of the fixed block 21, and a connecting column 35 is also fixedly connected to the rotating shaft 22, one end of the connecting column 35 extends to the outside of the rotating shaft 22 and is fixedly connected to a piston rod 33, and both ends of the piston rod 33 extend into the pipe 31 and the pipe 4 32 respectively, and the piston rod 33 can move inside the two respectively, and two cylindrical filter screens 34 are fixedly connected to the base 14, and the bottom ends of the pipe 31 and the pipe 4 32 extend into the two cylindrical filter screens 34 respectively;

[0037] By adopting the above scheme, the rotation of the rotating shaft 22 will also drive the connecting column 35 and the piston rod 33 to rotate, so that the two ends of the piston rod 33 move inside the pipe three 31 and the pipe four 32 respectively. At this time, the bottom ends of the pipe four 32 and the pipe three 31 will respectively draw the transformer oil into the pipe three 31 or the pipe four 32 through the bottom ends of the pipe three 31 and the pipe four 32 due to the suction action of the piston rod 33. At this time, due to the continuous suction of the transformer oil inside the pipe three 31 and the pipe four 32 and the resistance to the movement of the piston rod 33, the sensitivity of the floating block 24 when floating or falling is increased through the connecting column 35, the rotating shaft 22 and the connecting rod 23, thereby ensuring the stability of the device in measuring the oil level inside the oil pillow 1.

[0038] like Figure 1 , Figure 2 , Figure 4-Figure 6 , Figure 8 and Fig. 9 As shown, a housing 15 is fixedly connected to the inner wall at one end of the oil pillow 1; the adjustment component 4 includes a cross pipe 41 fixedly sleeved on the middle of the pipe three 31 and the pipe four 32, respectively; a transmission rod 44 is movably connected inside the housing 15, one end of the transmission rod 44 extends to the outside of the oil pillow 1 and is fixedly connected to a fan blade 45, a V-shaped groove 43 is provided inside the transmission rod 44, a connecting rod 42 is movably connected inside the transmission rod 44, a convex shaft 47 that can slide in the V-shaped groove 43 is fixed on the connecting rod 42, one end of the connecting rod 42 passes through the fan blade 45 and extends to the inside of the oil pillow 1, a through hole 2 422 and a through hole 3 423 are provided on the connecting rod 42, the through hole 2 422 is connected to the pipe three 31, and the through hole 3 423 is connected to the pipe four 32;

[0039] A limiting groove 421 is provided on the connecting rod 42, and a limiting block 411 capable of sliding in the limiting groove 421 is provided on the cross pipe 41;

[0040] The adjustment assembly 4 also includes an elastic rod 46 fixedly sleeved on the transmission rod 44 and located outside the oil pillow 1. The bottom end of the elastic rod 46 is a tension spring and is fixedly connected to the oil pillow 1.

[0041] In the initial state, the elastic rod 46 is kept in a vertical state by its own tension, and the fan blade 45 is kept in a vertical state. At this time, the convex shaft 47 is at the bend of the V-shaped slide groove 43;

[0042] By adopting the above scheme, the wind force in windy weather blows the fan blades 45 and causes the transmission rod 44 to drive the V-shaped groove 43 to rotate. At the same time, due to the limit block 411 sliding in the limit groove 421 to limit the connecting rod 42, the V-shaped groove 43 will force the convex shaft 47 to slide in the V-shaped groove 43 and cause the connecting rod 42 to move away from the elastic rod 46, thereby causing the through hole 2 422 and the pipe 3 31, and the through hole 3 423 and the pipe 4 32 to be misaligned. At this time, the connecting part between the upper part of the pipe 3 31 and the cylindrical filter screen 34 through the through hole 2 422 and the upper part of the pipe 4 32 and the cylindrical filter screen 34 through the through hole 3 423 is reduced. At this time, the force of the piston rod 33 to suck the transformer oil through the pipe 3 31 and the pipe 4 32 respectively increases, thereby increasing the damping of the piston rod 33, thereby ensuring that the device can stably measure the oil level inside the oil pillow 1 in windy weather.

[0043] like Figure 1 , Figure 2 , Figure 4 and Fig. 9 As shown, the projection of the blade portion on the fan blade 45 in the vertical direction and the projection of the transmission rod 44 in the vertical direction form an angle;

[0044] One end of the oil pillow 1 is also fixedly connected to two protrusions 16, which are arranged in symmetrical directions. When the elastic rod 46 rotates, it can abut against one of the protrusions 16;

[0045] With the above solution, through the design of the transmission rod 44, when the wind blows from the side, due to the inclined setting of the fan blades 45, the wind can still cause the fan blades 45 to rotate;

[0046] When the elastic rod 46 abuts against one of the protrusions 16 , the elastic rod 46 cannot continue to rotate, thereby preventing the wind from blowing the elastic rod 46 to cause it to continue rotating.

[0047] like Figure 2 , Figure 4-Figure 6 and Figure 8 As shown, the regulating assembly 4 is also provided with a cleaning assembly 5 for cleaning the external sediment of the cylindrical filter screen 34;

[0048] The cleaning assembly 5 includes a bending rod 51 hinged on the connecting rod 42, and two straight slots 52 are formed on the bending rod 51. A scraper 53 is movably sleeved on the outside of the cylindrical filter 34, and a cross bar 54 that can slide horizontally inside the straight slot 52 is fixedly connected to the outer periphery of the scraper 53;

[0049] By adopting the above solution, the movement of the connecting rod 42 also drives the bending rod 51 to move, so that the straight notch 52 forces the cross bar 54 to rotate and drives the scraper 53 to rotate to clean the sediment outside the cylindrical filter 34, thereby ensuring that the pipeline 3 31 and the pipeline 4 32 can be stably connected to the transformer oil inside the oil pillow 1 through the cylindrical filter 34;

[0050] It is worth noting that the length of the straight slot 52 is less than twice the length of the cross bar 54 . In this case, when the bending rod 51 moves, the straight slot 52 can drive the cross bar 54 to move.

[0051] The working principle and use process of the present invention:

[0052] When the oil level inside the oil pillow 1 changes, the float 24 will change with the change of the oil level. At this time, the float 24 will drive the rotating shaft 22 to rotate through the connecting rod 23, thereby changing the contact position between the slider 26 and the concave surface of the arc resistor 25. At this time, the current after the slider 26 passes through the arc resistor 25 will change with the change of the contact position between the slider 26 and the concave surface of the arc resistor 25. Then, the control circuit will convert the current signal into the height of the liquid level inside the oil pillow 1 and transmit the data to the monitoring terminal;

[0053] When the transformer oil level inside the oil pillow 1 changes too quickly, the rotation of the shaft 22 will also drive the piston rod 33 to rotate through the connecting column 35, so that the two ends of the piston rod 33 move inside the pipe three 31 and the pipe four 32 respectively. At this time, the bottom ends of the pipe four 32 and the pipe three 31 will respectively draw the transformer oil into the pipe three 31 or the pipe four 32 through the bottom ends of the pipe three 31 and the pipe four 32 due to the suction effect of the piston rod 33. At this time, due to the continuous suction of the transformer oil inside the pipe three 31 and the pipe four 32, the resistance to the movement of the piston rod 33 is generated, so that the sensitivity of the floating block 24 when floating or falling is increased through the connecting column 35, the shaft 22 and the connecting rod 23, thereby ensuring the stability of the device in measuring the oil level inside the oil pillow 1;

[0054] When it is windy, in order to avoid the shaking of the transformer or the oil pillow 1 which causes the shaking of the oil level inside the oil pillow 1, the wind will blow the fan blades 45 and make the transmission rod 44 drive the V-shaped groove 43 to rotate. At the same time, due to the limit block 411 sliding in the limit groove 421 to limit the connecting rod 42, the V-shaped groove 43 will force the convex shaft 47 to slide in the V-shaped groove 43 and make the connecting rod 42 move away from the elastic rod 46, so that the through hole 2 422 and the pipe 3 31, the through hole 3 423 and the pipe 4 32 are misaligned. At this time, the connecting part between the upper part of the pipe 3 31 and the cylindrical filter 34 through the through hole 2 422 and the upper part of the pipe 4 32 and the cylindrical filter 34 through the through hole 3 423 is reduced. At this time, the force of the piston rod 33 to suck the transformer oil through the pipe 3 31 and the pipe 4 32 respectively increases, thereby increasing the damping of the piston rod 33, thereby ensuring that the device can stably measure the oil level inside the oil pillow 1 in windy weather;

[0055] The movement of the connecting rod 42 will also drive the bending rod 51 to move, so that the straight slot 52 forces the cross bar 54 to rotate and drives the scraper 53 to rotate to clean the sediment outside the cylindrical filter 34, thereby ensuring that the pipeline three 31 and the pipeline four 32 can be stably connected to the transformer oil inside the oil pillow 1 through the cylindrical filter 34.
