基于介电响应法判绝缘纸的老化状态

Aging State of Insulation Paper Based on Dielectric Response Methods

电力变压器在当今社会生产和生活中扮演者至关重要的角色,其绝缘性能的好坏直接决定着变压器的使用寿命。判断变压器绝缘纸的老化状态,预测其剩余寿命变得尤为重要。介电响应法是一种无损于绝缘纸的判绝缘纸老化状态的方法,本文主要介绍了基于介电响应法判绝缘纸老化状态的几种方法,以及它们各自的优缺点和实用性。

The power transformer plays a crucial role in the production and life of modern society, its insulation performance directly determines the service life of the transformer. The transformer insulation aging state judgment paper, remaining life prediction has become particularly important. The dielectric response method is a nondestructive in insulation paper sentenced state method of paper aging insulation, this paper mainly introduces the dielectric response method based on several methods of insulation paper aging to the state, and their respective advantages and disadvantages and practicability.
