Description
Technical Field
The invention belongs to the field of transformers, and particularly relates to a transformer oil monitoring system and a monitoring method thereof.
Background
Transformer oil: is a fractional distillation product of petroleum, and its main components are paraffin, naphthenic saturated hydrocarbon, aromatic unsaturated hydrocarbon and other compounds. Commonly known as square greenhouse oil, light yellow transparent liquid with relative density of 0.895. The freezing point is more than-45 ℃. The transformer oil is a mineral oil obtained by distillation and refining of natural petroleum, and is a mixture of pure, stable, low-viscosity, good-insulation and good-cooling liquid natural hydrocarbons obtained by acid-base refining of lubricating oil fractions in the petroleum. Commonly known as square greenhouse oil, light yellow transparent liquid.
The transformer oil has the main functions of: first, insulating function: transformer oil has a much higher dielectric strength than air. The insulating material is immersed in oil, not only to improve the insulating strength, but also to protect against moisture. Secondly, heat dissipation: transformer oils have a high specific heat and are commonly used as coolants. The heat generated during the operation of the transformer enables the oil close to the iron core and the winding to be heated, expanded and raised, and the heat is dissipated through the radiator through the up-down convection of the oil, so that the normal operation of the transformer is ensured. Thirdly, arc extinction function: on oil circuit breakers and on-load tap changers of transformers, arcing occurs when contacts are switched. The transformer oil has good heat conduction performance, and can separate and touch a large amount of gas under the high-temperature action of the electric arc to generate larger pressure, so that the arc extinguishing performance of the medium is improved, and the electric arc is quickly extinguished.
Reference can be made to a chinese patent with publication number CN109058769A, which discloses a transformer oil leakage online monitoring and emergency treatment system and method, relating to the field of transformer monitoring.

The transformer oil leakage monitoring system comprises a transformer oil leakage pool, an oil discharge pipeline, an accident oil pool, an oil leakage sensor, a rainwater ditch, a cable ditch, a communication module, a monitoring system, a control unit, an emergency processing device and a rainwater ditch valve.
