一种低温型混合绝缘油的制备方法
摘要：
一种低温型混合绝缘油的制备方法，本发明涉及一种低温型混合绝缘油的制备方法。本发明的目的是为了解决现有混合绝缘油凝点过高，不适用于寒冷地区的问题。本发明方法为：一、处理矿物绝缘油和植物绝缘油，然后混合，制得混合绝缘油A；二、制得添加剂母液；三、将混合绝缘油A和添加剂母液混合，然后静置，制得低温型混合绝缘油；本发明将矿物绝缘油和植物绝缘油通过特殊工艺进行混合，制备适于寒冷地区应用的低温型混合绝缘油，凝点低于-40℃。本发明应用于混合绝缘油的制备领域。
摘要（英）：

The invention relates to a preparation method of low-temperature mixed insulating oil. The invention aims to solve the problem that existing mixed insulating oil is too high in condensation point, andis not suitable for use in cold regions. The method comprises the following steps: 1, treating mineral insulating oil and vegetable insulating oil, and then performing mixing to obtain mixed insulating oil A; 2, preparing an additive mother liquor; 3, mixing the mixed insulating oil A with the additive mother liquor, and then performing standing to obtain the low-temperature mixed insulating oil.The mineral insulating oil and vegetable insulating oil are mixed through a special process to prepare the low-temperature mixed insulating oil suitable for cold regions, and the condensation point is lower than -40 DEG C. The method is applied to the field of preparation of mixed insulating oils.
