Abstract

三单相变压器,属于电器变压器类。将铁芯中间 芯柱的宽度加宽为两个边芯柱的和;初级线圈分别于 边芯柱上,次级线圈于中间芯柱上。这种变压器有明 显的节省次级线圈的用料和节电的效果。

Description

本实用新型属于电器变压器类
现有的交流电焊机,是由日字形的铁芯、两组初级线圈及次级线圈组成的,日字形铁芯的三个芯柱的宽度相等,次级线圈缠绕于初级线圈的里侧或外侧。这种变压器的问题是:次级线圈的线材用量大,变压器的无功损耗大浪费电能。
本实用新型的目的是:提供一种节省次级线圈用料的、节省电耗的电焊机三单相变压器。
本实用新型的技术措施是:将日字形铁芯的中间芯柱加宽,使中间芯柱的宽度等于两个边芯柱宽度的和;次级线圈于中间芯柱上;两个初级线圈分别于两个边芯柱上。
本实用新型的电焊机三单相变压器,由于铁芯的中间芯柱加宽为两个边芯柱之和,次级线圈单独于中间芯柱上,经试验表明,次级线圈的用料可明显减少;两个初级线圈采用逆接法,又可将次级电压明显提高。节电省料效果明显。
图1是本实用新型的结构示意图;图2、图3是接线示意图。
图中1是日字形铁芯;现有焊机的铁芯,其三个芯柱是等宽的,本实用新型将中间芯柱的宽度加宽为两个边芯柱的和;两个等宽的边芯柱上分别缠绕两个初级线圈2和4,ABC三点分别是初级线圈2和4的抽头,加宽的中间芯铁上缠绕着次级线圈3,0102是次级线圈3的抽头。初级线圈2和4可采用正接法(见图2),也可采用逆接法(见图3)。
