Abstract

本实用新型涉及变压器领域,特别涉及一种干式变压器。它包括外罩,其特征是:在外罩的两侧的内面低于低压侧出线10cm高度处,通过风机支架各加装两台用于向外罩外排风的侧面风机,所述风机支架用螺栓紧固在外罩两侧的支柱上,变压器的高、低压侧各安装三台风机,每侧的风机并联于其本体降温风机上。本实用新型可有效减小外罩内部因变压器运行时产生的温度,延长变压器寿命,提高变压器运行时的各相性能。

Description

一种干式变压器
(一)      技术领域
本实用新型涉及变压器领域,特别涉及一种干式变压器。
(二)      背景技术
    大多数干式变压器为防尘、防异物进入变压器本体而加装外罩,虽然干式变压器每相采用双侧风机降温,但外罩内部空间狭小,空气流动不顺畅,从而造成干式变压器运行时散热效果不好,变压器绝缘材料老化加剧,影响变压器整体性能。
(三)      发明内容
    本实用新型为了弥补现有技术的缺陷,提供了一种可加快降温的的干式变压器。
本实用新型是通过如下技术方案实现的:
一种干式变压器,包括外罩,其特征是:在外罩的两侧的内面低于低压侧出线10cm高度处,通过风机支架各加装两台用于向外罩外排风的侧面风机,所述风机支架用螺栓紧固在外罩两侧的支柱上,变压器的高、低压侧各安装三台风机,每侧的风机并联于其本体降温风机上。
本实用新型的有益效果是:
本实用新型可有效减小外罩内部因变压器运行时产生的温度,延长变压器寿命,提高变压器运行时的各相性能。
(四)      附图说明
下面结合附图对本实用新型作进一步的说明。
图1为本实用新型的主视结构示意图;
图2为本实用新型的俯视结构示意图。
图中,1外罩,2低压侧出线,3侧面风机,4风机,5变压器,d 低压侧出线与侧面风机的距离。
(五)      具体实施方式
附图为本实用新型的具体实施例。如图1、图2所示,该种干式变压器,包括外罩1,在不改变外罩1尺寸的前提下,在外罩1的两侧的内面低于低压侧出线2 10cm(见图1中的d)高度处,通过风机支架各加装两台用于向外罩1外排风的侧面风机3,风机支架用螺栓紧固在外罩两侧的支柱上(图中未画出),变压器5的高、低压侧各安装三台风机4,每侧的风机4并联于其本体降温风机上;使温控器能同时启动外罩内所有降温风机,增加空气流速,及时把热空气排出,提高散热效果。
除说明书所述技术特征外,其余技术特征均为本领域技术人员已知技术。
