AI Technical Summary

Technical Problem

The sealing detection method of traditional oil-immersed transformers requires the oil tank to be completely immersed in water, and the leakage point cannot be clearly observed, which increases the detection difficulty.

Method used

Design an oil-immersed transformer seal detection equipment. By injecting detection liquid into the oil tank, using a pressure gauge to observe the pressure changes. If the pressure drops, it is proved that there is a leakage point. The detection liquid is circulated through the pump body to allow it to flow in the oil tank and leak out from the leakage point, which is convenient for observation.

Benefits of technology

The equipment can easily observe the leakage point of the fuel tank, improve the accuracy and efficiency of detection, and reduce the difficulty of detection.

Abstract

The utility model discloses an oil-immersed transformer leakproofness detection device which comprises a detection box, an oil tank is placed at the bottom of an inner cavity of the detection box through a placing plate, the left side of the top of the oil tank is communicated with an oil inlet pipe, the right side of the oil tank is communicated with an oil outlet pipe, and a pipe opening of the oil outlet pipe is movably connected with a first valve. The fourth valve and the first valve are closed, the third valve and the second valve are opened, detection liquid is pumped into the communicating pipe through starting of the pump body and enters the oil tank through the oil inlet pipe, after the needed detection liquid is injected, the third valve and the second valve are closed, the pump body is closed, the initial pressure value is observed through the pressure gauge, and after a period of time, the detection liquid is detected. The pressure of the oil tank is observed through the pressure gauge, if the pressure value of the pressure gauge is normal, the oil tank does not have a leakage point, if the pressure value drops, the leakage point is proved to appear, at the moment, only the valve IV and the valve I need to be opened, the pump body is started, and the pump body can only extract the detection liquid in the oil tank.
