施工现场,如果没有专用降压装置,又要得到安全电压时,该怎么办呢?只要工地上有一台普通电焊机,问题就解决了。将交流电焊机略加改制,不改变原电焊机任何部件和使用功能,就可得到一台电焊、变压两用机,即可得到理想的安全电压。电焊机实际上是一种特殊的降压变压器,因此这种装置改制的有关计算方法和变压器的有关公式一样。拆开电焊机的外罩壳,在电焊机任一绕组外再绕一组副线圈,即可获得所需的安全电
At the construction site, if there is no dedicated pressure-relief device and a safe voltage is to be obtained, what should we do? As long as there is a common electric welding machine on the construction site, the problem will be solved. By slightly modifying the AC welding machine, without changing any parts and functions of the original welding machine, an electric welding and variable pressure dual-purpose machine can be obtained, and an ideal safety voltage can be obtained. The welding machine is actually a special type of step-down transformer, so the calculation method for this type of device modification is the same as that of the transformer. Disassemble the casing of the welding machine and rewind a set of secondary coils outside any winding of the welding machine to obtain the required safe electricity.
