[0043] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0044] Embodiment 1

[0045] Refer to Figure 1 , this embodiment provides a transformer simulation training device.

[0046] The conveying mechanism 100 is used to convey the liquid flow into the device, simulating the oil required in the transformer oil injection process. The solution can be different types of liquids, such as water and diesel. Water is used to replace oil during the training work, which is simpler and more convenient. The solution tank 101 is fixedly installed at the bottom of the entire training device and is connected in through connection with the transmission assembly 102 above, and can send the solution into the simulation main body 103 above the training device through the transmission assembly 102, and then be conveyed by the simulation main body 103 into the corresponding pipeline. An air pump is also provided in the transmission assembly 102 for fault simulation teaching in the training device. The input gas represents the gas in the actual transformer. When the liquid infusion process ends, the air pump works and the fault simulation starts.

[0047] The teaching mechanism 200 is fixedly arranged above and on the side wall of the simulation main body 103 and is connected to the simulation main body 103 through pipelines. A simulation box 201 is fixedly arranged on the top of the simulation main body 103. The simulation box 201 plays the role of the gas relay in the transformer. A bracket is fixedly arranged on one side of the conveying mechanism 100 to install the simulation expansion end 202. The simulation expansion end 202 is used to play the role of the oil conservator in the transformer. A simulation collection box 203 is arranged at the bottom of the simulation expansion end 202. The simulation collection box 203 is used to play the role of the gas collection box in the transformer.

[0048] The simulation body 103, the simulation box 201, and the simulation expansion end 202 are connected by a pipeline, and the simulation box 201 is connected to the simulation collection box 203 by a pipeline, which is used to guide and transmit liquid and gas in subsequent fault simulation. The structure and pipelines included in the teaching institution 200 can be transparently designed to facilitate the trainees to intuitively see the flow direction of liquid and gas, thereby enhancing the effect of practical training.

[0049] Example 2

[0050] Reference Figures 1 to 3 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0051] At the top of the simulation body 103, a lifting end 204 is fixedly provided on one side of the simulation box 201, and the lifting end 204 is used to act as a lifting seat in the transformer. A breathing simulation tank 205 is also fixedly installed on one side of the simulation collection box 203. The breathing simulation tank 205 is directly connected to the air bag 202a in the simulation expansion end 202. When the air bag 202a in the simulation expansion end 202 contracts or expands under the action of liquid, it can directly act on the breathing simulation tank 205 through the pipeline.

[0052] A heat dissipation module 206 is fixedly installed on the other side of the simulation collection box 203. A pipeline is set through the inside of the heat dissipation module 206 to cooperate with the conveying mechanism 100 for liquid circulation. Once the corresponding liquid inlet valve of the conveying mechanism 100 is opened, the heat dissipation module 206 also needs to be opened synchronously. While performing subsequent heat dissipation in a timely manner, it can also ensure that the gas in the heat dissipation module 206 is discharged to prevent the gas from affecting the work in the fault simulation stage.

[0053] The simulation body 103 is connected to the simulation box 201 and the rising end 204 through a pipeline. When the simulation body 103 starts to transport liquid and gas, they can enter the simulation box 201 and the rising end 204 synchronously through the pipeline. The simulation box 201 is connected to the simulation expansion end 202 through a pipeline, and the simulation expansion end 202 is connected to the breathing simulation tank 205 through a pipeline. The simulation box 201 is connected to the simulation collection box 203 through a pipeline, and the simulation collection box 203 is connected to the solution box 101 through a pipeline. The simulation body 103, the heat dissipation module 206, and the transmission assembly 102 are connected through a pipeline.

[0054] The whole set of equipment connects more than 200 components of the teaching institution through multiple groups of pipes, and the flow status of liquid and gas can be observed intuitively through transparent pipes. A sensor module 201a is fixedly installed on the pipe between the simulation box 201 and the simulation expansion end 202. The sensor module 201a includes a flow rate sensor and a liquid level sensor. When the water flow exceeds the set value, a heavy gas signal is alarmed. The flow rate is controlled according to the speed of the injected gas, thereby realizing the demonstration process teaching of the heavy gas action. The liquid level sensor detects the water level, thereby detecting the presence of gas. When it exceeds the set value, a light gas signal is alarmed.

[0055] A status display terminal 202a is independently installed above the simulated expansion end 202. The status display terminal 202a is mainly a display screen and is electrically connected to the sensor module 201a. The signals and values ​​obtained by the flow rate sensor and the liquid level sensor can be intuitively reflected on the status display terminal 202a.

[0056] Example 3

[0057] Reference Figures 1 to 5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0058] The first step of the whole training simulation device is to inject flow into the transformer. The liquid pump valve on the outer wall of the transmission assembly 102 is opened in advance, and the exhaust valve on the top of the simulated expansion end 202 and the exhaust valve on the top of the simulated collection box 203 are opened, and then the liquid valve switch is started. In order to discharge the gas in the original device as much as possible, the corresponding gas valve needs to be opened, and the liquid can squeeze the gas to be discharged from the valve after entering.

[0059] After the liquid valve switch is activated, the solution tank 101 starts to transport liquid to the device through the transmission assembly 102. The liquid flows along the transmission assembly 102, enters the simulation box 201, and enters the simulation expansion end 202 and the simulation collection box 203 through the corresponding pipeline of the simulation box 201. After waiting for the simulation collection box 203 to be filled with solution, close the exhaust valve at the top of the simulation collection box 203. After the simulation expansion end 202 is filled with solution, close the exhaust valve at the top of the simulation expansion end 202.

[0060] After the airbag 202a in the simulated expansion end 202 is flattened by the solution, the total drain valve on the side wall of the simulated main body 103 is opened, and part of the solution flows back into the solution tank 101. The airbag 202a expands again due to the air pressure. At this time, the total drain valve on the side wall of the simulated main body 103 is closed again. At this point, the entire transformer is injected with flow, and the simulation preconditions are formed.

[0061] At this time, a fault simulation is required, the air valve is opened, and the air pump in the transmission assembly 102 starts working.

[0062] Gas enters the simulation box 201 and the corresponding connecting pipes, pressing the remaining liquid flow in the device into the simulation expansion end 202. The liquid flow squeezes the airbag 202a in the simulation expansion end 202. Then the air pump is turned off, and at this time, the fault simulation process ends, which is equivalent to generating a gas fault in the simulated transformer.

[0063] After the fault simulation is generated, troubleshooting needs to be carried out accordingly. First, open the liquid discharge valve at the bottom of the simulation collection box 203, and the liquid in the simulation collection box 203 starts to be discharged. At this time, the liquid and gas in the entire device start to flow towards the simulation collection box 203 again under the opening of the liquid discharge valve at the bottom of the simulation collection box 203.

[0064] Since the weight of the gas is much less than that of the liquid, the gas floats above the liquid, and a layered situation will occur inside the simulation collection box 203. When the layering effect no longer changes, it means that the gas has completely entered the simulation collection box 203. At this time, the gas needs to be discharged centrally. Open the exhaust valve at the top of the simulation collection box 203, and the gas is discharged, and the entire simulation troubleshooting work ends.

[0065] During the processes of liquid injection, simulation of faults, and simulation of troubleshooting of the entire device, the expansion or tightening of the airbag 202a will be involved, thus corresponding to the operation of the breathing simulation tank 205 because the pipeline in the breathing simulation tank 205 is directly connected to the airbag 202a. The breathing simulation tank 205 can well demonstrate the liquid seal effect of the transformer. A certain amount of solution is reserved in the breathing simulation tank 205, and the liquid level of the solution is 2 - 3 mm above the pipeline opening of the breathing simulation tank 205, just submerging the pipeline opening.

[0066] When the airbag expands, the liquid level in the breathing simulation tank 205 drops, and after the pipeline adsorbs a small amount of solution, the liquid level can be located below the pipeline opening. The small amount of adsorbed solution does not affect the normal operation of the pipeline and the airbag using air pressure. When the airbag tightens, bubbles appear on the liquid surface in the breathing simulation tank 205. The breathing simulation tank 205 is also made of transparent material, which is convenient for training personnel to directly observe the liquid seal principle of the transformer and the linkage effect with the airbag 202a from the outside.

[0067] When the liquid inlet valve is opened, the liquid flow will also enter the lifting end 204 through the bifurcation structure of the pipeline. There is solution in the lifting end 204. When the gas valve is opened, the gas will also enter the lifting end 204 through the bifurcation structure of the pipeline. The scenario in the lifting end 204 is the same as that in the simulation collection box 203. Due to the weight of the gas being much less than that of the liquid, a layering effect will occur in the lifting end 204. After the liquid-gas layering in the lifting end 204 stabilizes, open the exhaust valve at the top of the lifting end 204 to exhaust gas, and the simulation troubleshooting of the lifting end 204 ends.

[0068] Once the corresponding liquid inlet valve of the conveying mechanism 100 is opened, the heat dissipation module 206 also needs to be opened synchronously. While performing subsequent heat dissipation in a timely manner, it can also ensure the discharge of the gas in the heat dissipation module 206 to prevent the gas from affecting the work during the fault simulation stage.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
