超高压变电站变压器标准油样专用配置装置设计与应用

Design and application of special configuration device for transformer standard oil sample in UHV substation

针对现有变压器标准油样配置装置工作中会产生困油现象、配置完成的标准油样中的组份发生变化、随着循环时间组份变化数值不断增高、标准油样组份变化等问题,会对变压器的运行安全造成影响。文中提出了一种避免标准油组份变化的变压器标准油样配置装置。该装置设计中仅使用真空泵、控制阀、储油胶囊等结构,无需齿轮泵及其他机械结构,保证整个系统内的工作温度,从而避免油液组份发生变化,确保标准油样的质量。同时,该系统使用自动化设计,只需使用计算机启动配置工作,待设备自动配置完毕后,即可对设备内的油样用于变压器油色谱分析系统进行校准。此外,该设计的配置装置结构简单,设备的成本低、安装方便,具有良好的工程应用价值。

For the existing transformer standard oil sample configuration device,the oil trap phenomenon may occur,and the components in the standard oil sample may be changed.The value of the component changes with the cycle time may increase,and the standard oil sample composition,may affect the operation safety of the transformer.This paper proposes a transformer standard oil sample configuration device that avoids changes in standard oil composition.The design of the device uses only vacuum pumps,control valves,oil storage capsules,etc.,without the need for gear pumps and other mechanical structures.At the same time,the working temperature in the whole system is guaranteed,so as to avoid changes in the oil composition and ensure the quality of the standard oil sample.In addition,the configuration device designed in this paper has a simple structure,low cost of equipment,convenient installation,and has good engineering application value.
