Description

Technical Field

[0001] The invention relates to the technical field of transformer oil tanks, and in particular to a transformer oil tank with an oil level sensing structure and a use method thereof. Background Art

[0002] The transformer oil pillow is installed on the transformer's oil tank (corrugated oil tank). There is also a pipe sealed with "glass", called an "explosion-proof pipe". This is to prevent the oil temperature from rising rapidly and the volume from expanding sharply when the transformer fails. When the oil pillow can no longer hold the oil, the oil flow will break the glass and rush out of the explosion-proof pipe to protect the transformer from serious damage. The transformer oil tank (corrugated oil tank) is filled with oil, but the oil pillow of the transformer cannot be too full. The oil tank and the oil pillow are connected by a pipe. When there is a lack of oil in the oil tank, the oil in the oil pillow will flow down the pipe and be added to the oil tank to keep it full of oil. At the same time, when the transformer load increases, the oil temperature rises, the transformer oil expands, and the oil tank can no longer hold the oil, it will also flow up the pipe and flow back to the oil pillow.

[0003] The liquid inside the transformer oil tank mainly plays the role of insulation and cooling. The transformer oil tank needs to have sufficient liquid inside to keep it working normally during operation. When the liquid inside the transformer oil tank is reduced, it needs to be discovered and replenished in time. If it is not replenished in time, the transformer oil tank will be damaged. The liquid inside the transformer oil tank will produce oil residue after a period of time. The produced oil residue will stick to the surface of the oil level sensor, thereby affecting the monitoring operation of the oil level sensor. Summary of the invention

[0025] The present invention has the following beneficial effects:

[0026] The transformer oil tank of the present invention is provided with an oil level sensor inside, through which the liquid inside the transformer oil tank is monitored to prevent the transformer oil tank from being damaged due to a reduction in the liquid inside the transformer oil tank. When the hydraulic rod is started, the lifting frame pushes the shaking component to move inside the transformer oil tank through the hydraulic rod, and the shaking component is used to clean the oil residue inside the transformer oil tank to prevent the oil residue from accumulating on the surface of the oil level sensor and affecting the monitoring effect.

[0028] When the circular frame of the present invention moves downward, the sealing circular plate is squeezed by the liquid to push the spring sheet to deform, and when the sealing circular plate is separated from the circular frame, the sliding frame is pushed to move through the contact plate, and the sliding frame pushes the baffle plate to move toward the inside of the collecting frame through the push rod when moving.

[0029] After the floating plate of the present invention contacts the liquid inside the transformer oil tank, it will push the limiting ring to move upwards. The limiting ring moves on the surface of the round hole rod, thereby improving the stability of the floating plate during operation. When the limiting ring moves upwards, it pushes the sensing rod to move. The sensing rod pushes the observation plate to move inside the observation frame, so that the position of the observation plate can be observed through the observation frame, so as to timely discover the storage amount of liquid inside the transformer oil tank.
