Abstract

本实用新型涉及一种电力变压器,即低噪声变压器。它包括铁心,在铁心夹件两侧靠近夹螺杆的位置处加放绝缘板,长度与铁心厚度相同。这样在夹紧时,夹件保持原样无变形发生,通过两侧夹螺杆与中间U形螺杆的夹紧,铁心受力均匀,无机械噪音产生,达到降噪目的。

Description

低噪声变压器
技术领域 
本实用新型涉及一种电力变压器,即低噪声变压器。
背景技术
在现有技术中,变压器主要由铁心和绕组组成。当铁心夹件夹紧时,由于夹螺杆在铁心两长轴端两侧,使夹件出现两头向内变形,中间向外变形的情况,造成铁心受力不均,机械噪音非常大。
实用新型内容
本实用新型的目的是针对上述不足而提供一种结构简单,有效降低噪音的低噪声变压器。
本实用新型的技术解决方案是:低噪声变压器,包括铁心,在铁心夹件两侧靠近夹螺杆的位置处加放绝缘板,长度与铁心厚度相同。 
本实用新型的优点是:在铁心夹件两侧靠近夹螺杆的位置处加放绝缘板,铁心受力均匀,结构简单,无机械噪音产生,达到降噪目的。 
下面将结合附图对本实用新型的实施方式作进一步详细描述。 
附图说明
图1是本实用新型结构简图。 
具体实施方式
参见图1,低噪声变压器包括铁心1,在铁心1夹件两侧靠近夹螺杆2的位置加放绝缘板3,长度与铁心1厚度相同。这样在夹紧时,夹件保持原样无变形发生,通过两侧夹螺杆2与中间U形螺杆4的夹紧,铁心1受力均匀,无机械噪音产生,达到降噪目的。
