我国电焊机行业,目前对旋转式直流弧焊机以及硅整流式电焊机进行出厂校验,都是依据部颁标准JB2752-80直流弧焊电动发电机试验方法和JB2424-78整流弧焊机试验方法进行。其中额定负载试验一项是每一台焊机出厂校验的必检项目,以往都是采用负载电阻法,将焊机接通电源运行30分钟,使焊机达到一定的热态后进行试验读数。这种试验方法,在负载电阻上要耗费大量电能。在当前我国电力供应紧张的条件下,为了既不影响被试焊机的考核质量指标,又要符
China’s welding industry, the current DC rotary arc welding machines and silicon rectification welding factory inspection, are based on ministerial standards JB2752-80 DC arc welding motor generator test method and JB2424-78 rectifier arc welding machine test Method. One of the rated load test is a factory inspection of each welder must check the project, in the past are using load resistance method, the welder connected to the power running for 30 minutes, the welding machine to reach a certain hot test readings . This test method, the load resistance to spend a lot of energy. In the current conditions of China’s power shortage, in order to neither affect the test welder quality indicators, but also Fu
