System and method of transformer oil leakage online monitoring and emergency processing

Abstract

The invention discloses a system and a method of transformer oil leakage online monitoring and emergency processing, and relates to the field of transformer monitoring. At present, an online monitoring and emergency processing system of oil leakage to monitor whether transformer oil leaks or not at any time has not exited yet. The system comprises a transformer oil drainage tank, an oil dischargepipeline, an accident oil tank, oil leakage sensors, a rainwater ditch, a cable ditch, a communication module, a monitoring system, a control unit, an emergency processing device and a rainwater ditchvalve. The transformer oil drainage tank and the accident oil tank are connected through the oil discharge pipeline, multiple oil leakage sensors are arranged, the multiple oil leakage sensors are arranged in the transformer oil drainage tank, the accident oil tank, the rainwater ditch and the cable ditch; the communication module is connected with the oil leakage sensors and the monitoring system, the control unit is connected with the monitoring system and the emergency processing device, and the rainwater ditch valve is arranged in the rainwater ditch so as to prevent the leaked transformer oil from flowing out of a station. The technical scheme is simple in structure, reliable in work, and leakage degree and speed of the transformer oil can be accurately obtained.

Description

technical field [0001] The invention relates to the field of transformer monitoring, in particular to an on-line monitoring and emergency treatment system for transformer oil leakage. Background technique [0002] The substation is an important part of the power grid. The main transformer in the high-voltage substation is relatively large, and most of them are oil-filled equipment, especially in ultra-high voltage and ultra-high voltage AC substations. The weight of the main transformer can reach several hundred tons, and there is also a lot of transformer oil For tens of tons or more. [0003] Due to factors such as short circuit and overload of the transformer, the working temperature will be too high, the oil temperature will rise, and oil leakage will easily occur. The reasons for oil leakage include that the oil drain valve is not closed tightly, the bushing and the conductive rod are not matched or the gasket is not tightly sealed, and the connection parts of various ...

AI Technical Summary

Problems solved by technology

If the transformer explodes and other serious faults cause the oil to leak out of the oil unloading pool, such as cable trenches and rainwater ditches, the oil will flow out of the substation along with the rainwater pipelines and flow into rivers and rivers through ditches, causing serious water pollution and serious environmental problems

[0005] At present, there is no online monitoring and emergency treatment system for oil leakage that can monitor transformer oil leakage at all times and prevent transformer oil from leaking to the ditch outside the substation to ensure that oil leakage pollution is minimized
