为了确保安全,煤矿井下采掘工作面使用的煤电钻必须使用风电延时闭锁装置。简单地说,采掘工作面在使用煤电钻前,工作面必须先通风。目的是用风将工作面的沼气和煤尘及其他有害气体排出,然后再通电工作,这就更可靠地保证了安全。为了达到这一目的,我们将电钻电源从控制局扇的磁力起动器负荷侧接出,然后再接到控制 BZ80-2.5Z 电钻综合保护装置的磁力起动器电源侧。这样就达到了只有先起动局扇开关,工作
In order to ensure safety, the coal electric drill used in coal mining face must use the wind power delay locking device. In short, the face must be ventilated before using a coal electric drill. The purpose is to wind the methane and coal dust and other harmful gases discharge, and then energized work, which is more reliable to ensure safety. In order to achieve this goal, we will drill power from the control fan fan magnetic starter load side, and then connected to the control of BZ80-2.5Z drill comprehensive protection of the magnetic starter power supply side. This is achieved only the first start the bureau fan switch, work
