变压器油原油的组成分析!

发布时间2019-02-28  来源:http://www.wunqdctk.com

  因大多数故障情况下,局部放电总在电压较高处发生,所以变压器试验标准规定,一律用端子上的校准值作为视在放电量,即把所有不同部位放电的作用都折合为端子上的电荷变化量。
  In most cases, partial discharge always occurs at high voltage, so the transformer test standard stipulates that the calibration value on the terminal should be taken as the apparent discharge amount, that is, the effect of discharge at all different parts should be converted into the change of charge on the terminal.
  而测量变压器内油流带电引起的静电放电则与此不同,静电放电的形式,部位,形成原因等都有一定的随机性,虽可采用通常的局部放电测试回路作测量,但无法对放电量进行校准。直流静电放电为单个放电脉冲,放电能量较大,因此使用目前的局部放电测量仪,其灵敏度是足够的,可以通过观测放电脉冲幅值和次数对静电放电作定性判断。
  The measurement of electrostatic discharge caused by electrified oil flow in transformer is different from this. The form, location and cause of electrostatic discharge have certain randomness. Although the usual partial discharge test circuit can be used for measurement, the discharge can not be calibrated. DC electrostatic discharge is a single discharge pulse, which has a large discharge energy. Therefore, the sensitivity of the current partial discharge measuring instrument is sufficient. It can be qualitatively judged by observing the amplitude and number of discharge pulses.
  变压器油温和油的流速是影响油流带电很重要的因素。同时变压器内壁油漆为兰色,大量的红色漆皮是散热器内部脱落下来的。这些杂质污染了油,一方面使油介质损耗因数升高,另一方面油质变化使油带电度增加。局部流速过高的部位静电产生的速度大于泄放的速度,最终发生放电。由于影响油流带电的因素很多,多种因素综合作用达到一定状态将导致油流带电的产生。
  The temperature of transformer oil and the velocity of oil flow are very important factors affecting the electrification of oil flow. At the same time, the inner wall paint of transformer is blue, and a lot of red paint is falling off inside the radiator. These impurities contaminate oil, on the one hand, increase the loss factor of oil medium, on the other hand, the change of oil quality increases the charged degree of oil. The electrostatic discharge occurs when the local flow rate is too high, which is faster than the discharge rate. Because there are many factors affecting the electrification of oil flow, the combination of many factors will lead to the generation of electrification of oil flow.

  随着电网的不断扩建,变压器的需求量不断增大,其中配套的变压器油的需求量也日趋上升。生产变压器油的主要原料是环烷基和石蜡基原油。但环烷基原油是世界上一种稀有资源,仅占原油总量的2%左右。
  With the continuous expansion of the power grid, the demand for transformers is increasing, and the demand for matching transformer oil is also increasing. The main raw materials for transformer oil production are naphthenic and paraffin-based crude oil. However, naphthenic crude oil is a rare resource in the world, accounting for only about 2% of the total crude oil.
  与此同时变压器油生产厂家和用户关于石蜡基和环烷基变压器油有一些疑问,凯奥变压器油就两种原油的组成进行分析:
  At the same time, the manufacturers and users of transformer oil have some doubts about paraffin-based and naphthenic transformer oil. Kaio transformer oil analyses the composition of the two kinds of crude oil:
  通过采用质谱仪对两种变压器油的组成进行分析,从质谱的分析结果来看:石蜡基和环烷基变压器油的芳烃含量相近,主要差别是:石蜡基油的链烷烃含量较高,而环烷基油的环烷烃含量较高,特别是三环和四环的环烷烃。
  The composition of the two transformer oils was analyzed by mass spectrometer. The results of mass spectrometry analysis showed that the aromatics content of paraffin-based transformer oils and naphthenic transformer oils were similar. The main difference was that the paraffin-based transformer oils had higher alkanes content, while naphthenic oils had higher naphthenic hydrocarbons content, especially tricyclic and tetracyclic naphthenes.
