An oil-immersed transformer external oil quality real-time monitoring device

Abstract

The utility model discloses an oil -immersed transformer external oil quality real -time monitoring device, including transformer shell, transformer oil pillow, sampling pump, detection jar, oil return pump, oil quality sensor and man -machine interaction terminal. Transformer oil pillow is connected sampling pump entrance through oil inlet pipeline, and sampling pump export is connected detection jar oil inlet through the oil conveying pipeline, and detection jar oil outlet is connected oil return pump entrance through the backflow pipeline, and oil return pump export is connected transformer oil pillow through the oil return pipeline, and forms closed -loop oil circuit circulation, and oil quality sensor penetrates detection jar lateral wall, and the probe is immersed in oil liquid detection parameter, and man -machine interaction terminal is fixed in transformer shell, and is connected with oil quality sensor to show parameter and realize user interaction. The device can monitor oil quality parameter in real time, improve the timeliness of fault early warning, guarantee the detection accuracy, simplify the structure and the high integration, reduce the operation and maintenance cost, can also avoid oil liquid waste and pollution.
