Cutting - Edge Insulation Fluid Innovation
Transformer oil, an essential insulating medium for electrical equipment, is largely refined from petroleum and primarily composed of alkanes and cycloalkanes. With superior electrical insulation, it can efficiently separate high-voltage parts inside the transformer to stop leakage and short circuits. Thanks to its excellent thermal conductivity, the heat produced during the transformer's operation is rapidly transferred, preventing overheating and damage. It also has a degree of arc-extinguishing ability, swiftly quenching the arc when the switching device cuts off the current and generates an arc.

The transformer is an essential element in the power grid infrastructure. Whether the transformer operates properly is related to the safety of the power grid, and the transformer oil is vital for the reliable operation of the transformer. Therefore, we need to do a thorough job in the selection, utilization, and control of transformer oil to ensure the safe operation of the transformer. When it comes to the selection rules, first of all, the oil's performance should be pondered. Its quality must meet the requirements set by the equipment's voltage level, the ambient temperature at the position, and other relevant factors. In addition, the compatibility between the oil and other associated insulating materials should also be regarded.

1. Environmental Friendliness of Transformer Oil
Environmental monitoring: Routine environmental assessments and maintenance of transformers and other power equipment are essential for effectively reducing leak risks.
The implementation of an oil spill monitoring system allows for the early detection of issues, facilitating timely intervention.
Spill contingency measures: Developing and executing a comprehensive spill contingency plan is vital for ensuring a quick response to spills and mitigating their environmental effects. Furthermore, training staff in emergency response techniques equips them to act promptly in crisis situations.
2. Factors Affecting Service Life
To protect the lifespan of transformer oil, it is vital to regularly conduct quality analysis and testing. This includes measuring insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, and microwater content in the oil. A thorough evaluation of these parameters reveals whether the oil has moisture, impurities, or is aging. If any issues are detected, the first response may be to attempt oil regeneration via filtration. However, if this method is not viable or if the oil quality is significantly impaired, it will be necessary to replace the transformer oil.
