Description

Technical Field

[0001] The invention relates to the field of transformers, and in particular to a transformer with adjustable no-load current. Background Art

[0002] As the core equipment for power transmission and distribution, the no-load current characteristics of the transformer directly affect the stability of the voltage. The transformer with adjustable no-load current can optimize the no-load characteristics of the transformer by adjusting the no-load current, thereby stabilizing the output voltage and reducing the impact of voltage fluctuations on user equipment. In actual use, when the transformer is working, the internal winding will generate heat due to long-term work. When the external ambient temperature is high, the superposition of the two temperatures will often cause the heat accumulation of the insulating oil inside the transformer to accelerate, causing the temperature to rise beyond the safety threshold and affect the safety performance of the adjustable transformer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the use scenario of the adjustable transformer, when the ambient temperature of the external environment of the adjustable transformer is high, since the outer arc surface of the gas-heating cavity is made of a material with good thermal conductivity, the external heat can be quickly conducted to the inside of the gas-heating cavity through the gas-heating cavity, thereby causing the thermosensitive gas inside the gas-heating cavity to expand rapidly, and the thermosensitive gas can enter the upper part of the side bin through the conduit, thereby forcing the piston plate inside the side bin to descend. When the piston plate descends, the insulating oil inside the side bin will be forced into the bottom bin through the outlet, thereby forcing the original insulating oil inside the bottom bin out of the bottom bin and into the upper part of the shell, thereby achieving mixing and cooling of the insulating oil in the upper part of the shell, thereby achieving timely cooling of the insulating oil inside the adjustable transformer in a high-temperature external environment, which is beneficial to actual use.

[0016] 2. When the insulating oil in the bottom bin is forced out and mixed into the insulating oil around the transformer body, the insulating oil in the upper part of the adjustable transformer that has been heated up due to long-term operation of the transformer body will be forced into the circulation chamber through the oil inlet, thereby isolating the original high-temperature insulating oil. Combined with the newly added low-temperature insulating oil, the temperature around the transformer body can be quickly cooled down. At the same time, it can effectively avoid the accumulation of insulating oil temperature, which causes the temperature to rise beyond the safety threshold and affect the safety performance of the adjustable transformer, thereby effectively improving the safety of the transformer.

[0017] 3. Multiple transfer chambers are set up inside the adjustable transformer. By mobilizing the insulating oil in various places inside the shell, the internal temperature of the adjustable transformer can be quickly transferred and cooled, avoiding the situation where heat is easily accumulated in a single chamber. At the same time, when the external temperature drops, the volume of the thermosensitive gas in the gas heat chamber will shrink, which will cause the upper part of the side bin to be in a negative pressure state, which will cause the piston plate to rise, so that the insulating oil in the upper part of the shell will enter the side bin through the side port, realizing the closure of the insulating oil circulation in each transfer chamber, which is beneficial to the long-term use of the adjustable transformer.

[0018] 4. When the insulating oil inside the side bin is discharged through the oil guide pipe, it will drive the guide vane to rotate through the oil guide pipe, and the guide vane can drive the fixed shaft to rotate, and the fixed shaft can drive the gear ring 2 and the gear ring 1 to rotate, and the gear ring 1 can use the rotating shaft and the rotating frame to drive the main frame to rotate. When the insulating oil inside the bottom bin is mixed into the upper part of the shell through the oil change port, the acidity sensor 1 at the end of the main frame can detect the acidity of the insulating oil discharged through the oil change port. The rotation of the acidity sensor 1 can achieve sufficient and continuous detection of the discharged insulating oil, so as to avoid missing some deteriorated insulating oil when the acidity sensor is in a relatively fixed position, resulting in incomplete detection results.

[0019] 5. When the insulating oil inside the adjustable transformer is circulating and the piston plate rises to draw the insulating oil inside the shell into the side bin, the insulating oil will pass through the acidity sensor 2. The acidity of the insulating oil flowing through can be detected by the acidity sensor 2. In conjunction with the acidity sensor 1, a comprehensive detection of the insulating oil inside the shell and the bottom bin can be achieved. At the same time, by allowing the insulating oil to circulate, the deterioration and aging of the insulating oil can be discovered in time during actual use, which is beneficial to actual use.

DETAILED DESCRIPTION

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 7The transformer with adjustable no-load current shown in the figure comprises an adjustable transformer 1, which comprises a shell 101, a partition 115 is fixedly connected to the lower part of the shell 101, a bottom bin 110 is arranged at the lower part of the partition 115, side bins 112 are fixedly connected to the middle parts of both sides of the shell 101, and gas heat chambers 105 are installed on both sides of the shell 101, and a heat-sensitive gas with a high expansion coefficient is arranged inside the gas heat chamber 105.

The limit rod 117 is fixedly connected to the inside of the side bin 112, and the piston plate 119 is slidably connected to the limit rod 117.

[0030] Furthermore, in a specific implementation, when the adjustable transformer 1 is installed in the use scenario, when the ambient temperature of the external environment of the adjustable transformer 1 is high, since the outer arc surface of the gas-heating chamber 105 is a material with good thermal conductivity, the external heat can be quickly conducted to the inside of the gas-heating chamber 105 through the gas-heating chamber 105, thereby causing the thermosensitive gas inside the gas-heating chamber 105 to expand rapidly, and the thermosensitive gas can enter the upper part of the side bin 112 through the conduit 108, thereby forcing the piston plate 119 inside the side bin 112 to descend. When the piston plate 119 descends, the insulating oil inside the side bin 112 will be forced into the bottom bin 110 through the outlet 118, thereby forcing the original insulating oil inside the bottom bin 110 out of the bottom bin 110 and into the upper part of the shell 101, thereby achieving mixing and cooling of the insulating oil in the upper part of the shell 101, thereby achieving timely cooling of the insulating oil inside the adjustable transformer 1 in a high-temperature external environment, which is beneficial to actual use.

[0031] The bottom sides of the shell 101 are fixedly connected with the bottom frame 103, the front and rear parts of the shell 101 are installed with evenly distributed heat sinks 104, the inside of the shell 101 is installed with the transformer body 109, the transformer body 109 is installed on the top of the partition 115, the top cover 102 is installed on the top of the shell 101, and the middle part of the top of the top cover 102 is provided with an adjustment knob, which is connected to the transformer body 109 through a tap switch, a discharge pipe 106 is installed on one side of the bottom bin 110, and a bracket 111 is fixedly connected to the inner edge of the shell 101;

[0032] Furthermore, in a specific implementation, people can realize voltage conversion of the power consumption area through the adjustable transformer 1, and can adjust the engagement state of the tap switch inside the adjustable transformer 1 through the adjustment knob on the upper part of the adjustable transformer 1. By changing the turns ratio of the winding of the transformer body 109, the no-load current of the adjustable transformer 1 can be adjusted.

[0033] Among them, the side bins 112 are arranged on both sides of the transformer body 109, and a plurality of side ports 129 are opened at the lower part of the side bin 112 close to the transformer body 109. The lower part of one end of the side bin 112 close to the transformer body 109 is fixedly connected with a fixing frame 122, and a plurality of acidity sensors 130 are installed at the bottom of the fixing frame 122. A plurality of guide ports 118 are fixedly connected to the bottom of the side bin 112, and the guide ports 118 penetrate the bottom of the side bin 112 and the partition 115. The front and rear sides of the compressor body 109 are provided with circulation chambers 107, which are installed at the front and rear parts of the top of the partition 115. The top of the circulation chamber 107 is provided with oil inlets 113 on both sides, and the bottom of the circulation chamber 107 is connected to the inside of the bottom bin 110 through the oil outlet 123. A plurality of oil change ports 114 are provided on both sides of the middle of the partition 115, and one-way valves are installed inside the oil inlet 113, the oil change port 114, the guide port 118, the oil outlet 123 and the side port 129.

[0034] Furthermore, in a specific implementation, when the insulating oil in the bottom bin 110 is forced out and mixed into the insulating oil around the transformer body 109, the insulating oil in the upper part of the adjustable transformer 1 that has been heated up by the long-term operation of the transformer body 109 will be forced into the circulation chamber 107 through the oil inlet 113, thereby isolating the original insulating oil with a higher temperature. The newly added insulating oil with a lower temperature can quickly cool down the temperature around the transformer body 109, and can effectively avoid the accumulation of the insulating oil temperature, which causes the temperature to rise beyond the safety threshold and affect the safety performance of the adjustable transformer 1. 1 is provided with a plurality of transfer chambers, and the internal temperature of the adjustable transformer 1 can be quickly transferred and cooled by mobilizing the insulating oil in various places inside the shell 101, so as to avoid the situation that heat is easily accumulated in a single chamber. At the same time, when the external temperature decreases, the volume of the heat-sensitive gas in the gas-heating chamber 105 will shrink, so that the upper part of the side bin 112 will be in a negative pressure state, which will cause the piston plate 119 to rise, so that the insulating oil in the upper part of the shell 101 will enter the side bin 112 through the side port 129, so as to realize the closure of the insulating oil circulation in each transfer chamber, which is beneficial to the long-term use of the adjustable transformer 1.

[0035] Among them, an oil guide pipe 125 is arranged at the bottom of one guide outlet 118, and the oil guide pipe 125 is fixedly connected to the bottom of the partition 115, and the end of the oil guide pipe 125 away from the partition 115 is fixedly connected to the guide chamber 127, and the middle part of the end of the guide chamber 127 away from the oil guide pipe 125 is fixedly connected to the reserved opening 132, and the guide impeller 116 is arranged inside the guide chamber 127, and the guide impeller 116 is fixedly connected to the outer periphery of the fixed shaft 133, and the fixed shaft 133 is rotatably connected to the middle part of the guide chamber 127, and the guide chamber A second gear ring 126 is fixedly connected to the upper part of the outer periphery of 127, and a gear ring 124 is meshedly connected to one side of the second gear ring 126. The gear ring 124 is fixedly connected to the lower part of the outer periphery of the rotating shaft 128. A rotating frame 131 is fixedly connected to the top of the rotating shaft 128. A main frame 120 is installed in the middle of the rotating frame 131. Acidity sensors 121 are installed at both ends of the main frame 120. The main frame 120 is arranged on the upper part of the partition 115. The top of the rotating shaft 128 passes through the middle of the partition 115. The rotating shaft 128 is rotatably connected to the partition 115.

[0036] Furthermore, in a specific implementation, when the insulating oil in the side bin 112 is discharged through the oil guide pipe 125, the insulating oil will pass through the guide bin 127 and be discharged from the reserved port 132. When the insulating oil passes through the guide bin 127, the guide vane 116 is driven to rotate, and the guide vane 116 can drive the fixed shaft 133 to rotate, and the fixed shaft 133 can drive the gear ring 2 126 to rotate synchronously. When the gear ring 2 126 rotates, it drives the meshing gear ring 1 124 to rotate, and the gear ring 1 124 is driven to rotate. 24 can utilize the rotating shaft 128 and the rotating frame 131 to drive the main frame 120 to rotate. When the insulating oil inside the bottom bin 110 is mixed into the upper part of the shell 101 through the oil change port 114, the acidity sensor 121 at the end of the main frame 120 can detect the acidity of the insulating oil discharged through the oil change port 114. The rotation of the acidity sensor 121 can achieve sufficient and continuous detection of the discharged insulating oil, thereby avoiding the omission of some deteriorated insulating oil when the position of the acidity sensor 121 is relatively fixed, resulting in an incomplete detection result.

[0037] Working principle:

[0038] People can use the adjustable transformer 1 to achieve voltage conversion in the power consumption area, and can adjust the engagement status of the tap switch inside the adjustable transformer 1 through the adjustment knob on the upper part of the adjustable transformer 1. By changing the turns ratio of the winding of the transformer main body 109, the no-load current of the adjustable transformer 1 can be adjusted. In actual use, when the adjustable transformer 1 is installed in the use scenario, when the ambient temperature outside the adjustable transformer 1 is high, since the outer arc surface of the gas heating cavity 105 is a material with good thermal conductivity, the external heat can be quickly conducted to the inside of the gas heating cavity 105 through the gas heating cavity 105, thereby causing the thermosensitive gas inside the gas heating cavity 105 to expand rapidly, and the thermosensitive gas will enter the side warehouse through the conduit 108. 112, thereby forcing the piston plate 119 inside the side bin 112 to descend. When the piston plate 119 descends, the insulating oil inside the side bin 112 will be forced into the bottom bin 110 through the outlet 118, so that the original insulating oil in the bottom bin 110 can be forced out of the bottom bin 110 and introduced into the upper part of the shell 101, so as to achieve the mixing and cooling of the insulating oil in the upper part of the shell 101, so as to achieve the timely cooling of the insulating oil in the adjustable transformer 1 in the external high temperature environment, which is beneficial to actual use. When the insulating oil in the bottom bin 110 is forced out and mixed into the insulating oil around the transformer main body 109, the insulating oil in the upper part of the adjustable transformer 1 that has been heated up due to the long-term operation of the transformer main body 109 will pass through the oil inlet. 113 is forced into the circulation chamber 107 to isolate the original high-temperature insulating oil. Together with the newly added low-temperature insulating oil, the temperature around the transformer body 109 can be quickly cooled down. At the same time, it can effectively prevent the insulating oil temperature from accumulating, causing it to rise beyond the safety threshold and affect the safety performance of the adjustable transformer 1. A plurality of transfer chambers are arranged inside the adjustable transformer 1. By mobilizing the insulating oil at various locations inside the shell 101, the temperature inside the adjustable transformer 1 can be quickly transferred and cooled down, avoiding the situation where heat is easily accumulated in a single chamber. At the same time, when the outside temperature drops, the volume of the heat-sensitive gas inside the gas-heat chamber 105 will shrink, which will cause the upper part of the side bin 112 to be in a negative pressure state, thereby The piston plate 119 will be caused to rise, so that the insulating oil in the upper part of the shell 101 will enter the side bin 112 through the side port 129, so as to realize the closure of the insulating oil circulation in each transfer chamber, which is beneficial to the long-term use of the adjustable transformer 1. When the insulating oil in the side bin 112 is discharged through the oil guide pipe 125, the insulating oil will pass through the oil guide pipe 125, and the insulating oil will pass through the guide bin 127 and be discharged from the reserved port 132. When the insulating oil passes through the guide bin 127, it will drive the guide vane 116 to rotate, and the guide vane 116 can drive the fixed shaft 133 to rotate, and the fixed shaft 133 can drive the gear ring 2 126 to rotate synchronously, and when the gear ring 2 126 rotates, it will drive the meshing gear ring 1 124 to rotate.The main frame 120 can be driven to rotate by the rotating shaft 128 and the rotating frame 131 through the gear ring 124. When the insulating oil in the bottom bin 110 is mixed into the upper part of the shell 101 through the oil change port 114, the acidity sensor 121 at the end of the main frame 120 can detect the acidity of the insulating oil discharged through the oil change port 114. The rotation of the acidity sensor 121 can achieve sufficient and continuous detection of the discharged insulating oil, thereby avoiding the omission of some deteriorated insulating oil when the position of the acidity sensor 121 is relatively fixed, resulting in an incomplete detection result. At the same time, when the insulating oil inside the adjustable transformer 1 is circulating, the piston plate 119 rises to extract the insulating oil inside the shell 101 into the side bin 112, and the insulating oil passes through the acidity sensor 2 130. The acidity of the insulating oil passing through can be detected by the acidity sensor 2 130. In conjunction with the acidity sensor 1 121, the insulating oil inside the shell 101 and the bottom bin 110 can be fully detected. At the same time, by allowing the insulating oil to circulate, the deterioration and aging of the insulating oil can be discovered in time during actual use, which is beneficial to actual use.
