浅析变压器油的用途及颜色

变压器油是石油中的润滑油馏份经酸碱精制处理得到纯净稳定、粘度小、绝缘性好、冷却性好的液体天然碳氢化合物的混合物。变压器油的用途有:
Transformer oil is a mixture of liquid natural hydrocarbons which is purified, stable, low viscosity, good insulation and good cooling property by acid-base refining treatment of lubricating oil fraction in petroleum. The uses of transformer oil are as follows:
1、变压器中的油在运行时主要起散热冷却作用;
1, the oil in the transformer mainly plays the role of cooling and cooling when running.
2、对绕组等起绝缘和绝缘保养作用(保持良好绝缘状态);
2. Insulation and insulation maintenance for windings (maintain good insulation condition);
3、变压器油在高压引线处和分接开关接触点起消弧作用,防止电晕和电弧放电的产生;
3. Transformer oil plays an arc suppression role at the contact point of high voltage lead wire and tap switch to prevent corona and arc discharge.
4、变压器油被广泛用作液压安全阀内的液封。

4. Transformer oil is widely used as a liquid seal in hydraulic safety valve.
变压器油的颜色是什么?
What is the color of transformer oil?
良好的变压器油应该是清洁而透明的液体,不得有沉淀物、机械杂质悬浮物及棉絮状物质。如果其受污染和氧化,并产生树脂和沉淀物,变压器油油质就会劣化,颜色会逐渐变为浅红色,直至变为深褐色的液体。当变压器有故障时,也会使油的颜色发生改变一般情况下,变压器油呈浅褐色时就不宜再用了。另外,变压器油可表现为浑浊乳状、油色发黑、发暗。变压器油浑浊乳状,表明油中含有水分。油色发暗,表明变压器油绝缘老化。油色发黑,甚至有焦臭味,表明变压器内部有故障。
A good transformer oil should be a clean and transparent liquid, free of sediments, suspended mechanical impurities and cotton flocs. If it is contaminated and oxidized, and produces resins and sediments, the transformer oil will deteriorate, gradually turning light red to dark brown liquids. When the transformer is out of order, it will change the color of the oil. In general, when the transformer oil is light brown, it should not be used any more. In addition, transformer oil can be characterized by turbidity, blackening and darkening. The oil of the transformer is cloudy and milky, indicating that the oil contains moisture. Dark oil color indicates the aging of transformer oil insulation. The oil is black and even smelly, indicating that there is a malfunction inside the transformer.
