针对目前防爆变频器功率单元结构分散、布线杂乱、互换性低和维护麻烦等缺陷,提出矿用防爆变频器模块化插接式功率单元。这种功率单元采用模块化插接式设计,使得结构更加紧凑,布线整洁美观,并且通过插接式结构实现整体推拉,井下单人即可进行维修、更换电气元件。
Aiming at the defects such as scattered power structure, messy wiring, low compatibility and maintenance troubles, the explosion-proof inverter modular plug-in power unit is proposed. This power unit uses a modular plug-in design, making the structure more compact, wiring neat and beautiful, and through the plug-in structure to achieve the overall push and pull, single downhole maintenance, replacement of electrical components.
