Description

变压器
技术领域
一种电器设备，特别是一种变压器。
背景技术
根据现有技术的变压器主要具有这样的形式：初级线圈和次级线圈顺序地缠绕在单个线圈架上，芯通过线圈架的通孔结合到线圈架。为了避免漏电或是其他事故，通常会在磁芯和线圈架之间设置绝缘垫，但是磁芯在工作中会发热，促使绝缘垫的老化，降低变压器的使用寿命，现有技术还未解决这样的问题。
发明内容
为解决现有技术的不足，本发明的目的在于提供一种方便更换绝缘垫的变压器，从而减少成本，提高使用寿命。
为了实现上述目标，本发明采用如下的技术方案：
变压器，包括：缠绕线圈的线圈架，置于线圈架中心通孔内的磁芯，置于磁芯和线圈架之间的可更换的绝缘垫组件；绝缘垫组件组成有：两个相对设置的绝缘垫。
前述的变压器，绝缘垫组成有：隔离磁芯和线圈架之间的绝缘垫本体，置于绝缘垫本体上并卡接线圈架的限位部，延伸于绝缘垫本体的把手。
前述的变压器，把手设有放置人手的凹槽。
前述的变压器，限位部为卡接线圈架边缘的卡接凸起。
前述的变压器，线圈架上设有容纳线圈的放置槽。
前述的变压器，绝缘垫为橡胶垫。
本发明的有益之处在于：提供一种方便更换绝缘垫的变压器，从而减少成本，提高使用寿命。
附图说明
图1是本发明的一种实施例的截面图；
图2是本发明跟换绝缘垫时的一种实施例的截面图；
图中附图标记的含义：
1线圈架，2磁芯，3绝缘垫，301绝缘垫本体，302把手，303卡接凸起，4凹槽。
具体实施方式
以下结合附图和具体实施例对本发明作具体的介绍。
变压器，包括：缠绕线圈的线圈架1，置于线圈架1中心通孔内的磁芯2，置于磁芯2和线圈架1之间的可更换的绝缘垫组件；绝缘垫组件组成有：两个相对设置的绝缘垫3。
绝缘垫3组成有：隔离磁芯2和线圈架1之间的绝缘垫本体301，置于绝缘垫本体301上并卡接线圈架1的限位部，延伸于绝缘垫本体301的把手302。为了方便操作人员将绝缘垫3抽出，把手302设有放置人手的凹槽4。作为一种优选，限制绝缘垫3运动的极限位置，限位部为卡接线圈架1边缘的卡接凸起303。
防止线圈缠绕，线圈架1上设有容纳线圈的放置槽；作为一种优选，绝缘垫3选用成本低，且具有一定形变能力的橡胶垫。
这样的设计不仅方便抽出，和装入绝缘垫3，而且不需要重新更换变压器本身，只需要将老化的绝缘垫3更换就可继续使用，从而减少成本，提高使用寿命。
以上显示和描述了本发明的基本原理、主要特征和优点。本行业的技术人员应该了解，上述实施例不以任何形式限制本发明，凡采用等同替换或等效变换的方式所获得的技术方案，均落在本发明的保护范围内。
