我矿电气工段的同志们,为了解决生产跃进和加速基建对焊接工作的需要。利用土法制成了一台电抗电焊机。經过試驗,証明这种电焊机是很适用的。不但构造簡单,維护檢修方便,而且成本极低,焊接和截取質量合乎要求,在缺少电焊设备时,完全可以滿足生产需要。現簡要介紹如下: 一、基本原理及試驗數据这种电焊机是利用綫圈电阻及通过交流电产生感抗来降低电压,获得所需电流的原理制成的。变压器一相经电抗短路,因而調节綫圈的电抗,就可得到所需的电流(这个电流由焊条大小来決定),並能滿足 The comrades of our mine’s electrical engineering section have solved the need for welding and welding in order to solve production jumps and accelerate infrastructure. Using earth method made a resistance welding machine. After tests, it proved that this welding machine is very suitable. Not only is it simple in construction, convenient in maintenance and repair, but also in extremely low cost, welding and interception quality are required. In the absence of electric welding equipment, it can fully meet production needs. Now briefly introduced as follows: First, the basic principles and test data This welding machine is the use of coil resistance and AC inductive reactance to reduce the voltage, the principle of obtaining the required current made. A phase of the transformer is short-circuited by the reactance, so that adjusting the reactance of the coil can obtain the required current (this current is determined by the size of the electrode) and can satisfy
