KZG型动力制动柜为三相半控桥式整流装置在自动投入时,形成一个闭环系统,但是没有调节器对系统各参数进行校正,有几种原因会造成振荡。由于地方煤矿的现场分析水平较低,往往感到不好处理。随着制动装置的广泛使用,亟待找出克服振荡现象的方法。本文试对振荡现象进行初步分析并提出克服办法。 KZG-type dynamic brake cabinet for the three-phase half-controlled bridge rectifier in the automatic input, the formation of a closed-loop system, but no regulator to correct the system parameters, there are several reasons for oscillation. Due to the low level of on-site analysis of local coal mines, it is often felt badly handled. With the widespread use of braking devices, it is urgent to find ways to overcome the oscillation phenomenon. This paper attempts to analyze the phenomenon of oscillation and propose ways to overcome it.
