近年来我省机电部门为了适应我省小水电建设飞速发展的需要,研制生产了一大批无励磁机的小型水轮发电机。这些不带励磁机的水轮发电机优点很多,给我省小水电建设事业带来了不少好处。但因此类发电机是新产品,在产品质量方面还存在一些问题,而“起励”困难就是这类电机突出的弱点。此类发电机因为取消了专用的励磁机,所以必须设置另一种形式的励磁装置以解决发电机的励磁问题,这种新的励磁装置就是我们所讲的半导体整流励磁装置。先谈一下这种励磁装置是怎样进行工作的。大家知道,这类发电机电压的建立是这样 In recent years, the province’s electrical and mechanical departments in order to meet the rapid development of small hydropower construction in our province needs to develop and produce a large number of non-excitation machine small hydro-generator. These hydroelectric generators without exciter have many advantages, which have brought a lot of benefits to the province’s construction of small hydropower. However, the generator is a new product, and there are still some problems in product quality. The difficulty of “jacking up” is the outstanding weakness of such a motor. Because this kind of generator has canceled the special-purpose exciter, another kind of excitation device must be set up to solve the excitation problem of the generator. The new exciter device is what we call the semiconductor rectifier exciter. Let’s talk about how this excitation device works. We all know that this type of generator voltage is established
