摘要
煤矿井下使用的防爆变频器由于其使用环境的不同,在满足防爆要求外,还要求其使用过程更加稳定可靠,过载能力更强,对其他设备的干扰更小。以500 kW/1140 V四象限变频器为例,具体分析各主要器件运行时的参数,在保证其能稳定运行的前提下,合理选择器件的类型。
Explosion-proof frequency converters used in coal mine were different according to the environment, to meet the explosion-proof requirements, also requiring the use of the process to be more stable and reliable, strong overload capacity, less interference to other devices are also required. Taking 500 kW/1 140 V four quadrant converter as an example, analyzed the main components of the operating parameters concretely, to ensure the stability of its operation under the premise of a reasonable choice on the type of device.
