摘要

变压器铁芯、夹件的接地方式,直接关系到变压器的安全运行。近几年发现很多变电站变压器铁芯、夹件的接地是与油箱壳体绝缘引下至主接地网,改变了过去经油箱下部专用接地点接地的方式。本文通过对变压器铁芯、夹件的结构、功能分析,以及探讨两种不同接地方式下对变压器安全运行的影响,从而明确与油箱绝缘引下至主接地网的方式将影响变压器的安全运行;正确的接法应该是铁芯、夹件经油箱下部专用接地点接地。

Abstract

The grounding mode of transformer core and clamp is directly related to the safe operation of transformer. In recent years, many transformer cores have been found in substations, and the grounding of the clamps is caused by insulation from the oil tank shell to the main grounding grid, which has changed the way of special grounding through the lower part of the tank. In this paper, the structure and function of transformer core and clamp are analyzed, and the influence of two different grounding modes on the safe operation of transformer is discussed. Thus, it is clear that the way of insulation from the oil tank to the main ground grid will affect the safe operation of the transformer; The correct connection method should be the iron core, the clamp through the lower part of the special contact point grounding.

Key words: transformer; core; clamp; Grounding mode
