电焊机保护技术及装置的应用技巧
摘要
从促进安全生产和保护劳动者的角度出发
就电焊机及其线路系统和焊接操作者的保护装置进行介绍
主要包括剩余电流动作保护器、电焊机空载自动保护装置等
这些电器的主要职能是对电焊机及相关设备和操作人员起安全保护作用
保护范围主要是:电焊机过载
电焊机及其线路的短路
机壳和焊接回路漏电
电焊机及其线路直接接触触电和机壳与焊接回路漏电引起的间接接触触电
二次侧空载电压触电等。
Abstract
From the perspective of promoting safe production and workers protection
introduce the device of electric welding machine and circuit system and protect the welding operator
which mainly includes the residual current operated protection device
electric welder no-load automatic protection device. The main function of these appliances is to play the role of security protection for electric welding machine and related equipment and operating personnel. The scope of protection is mainly electric welding machine overload;short-circuit electric welding machine and its line;casing and the welding circuit leakage;electric welding machine and line in direct contact with the electric shock and the casing and the welding circuit leakage caused by indirect contact electric shock;secondary noload voltage electric shock.
