摘要
阳煤三矿机电科当前主通风机风门电源快切装置采用机械连锁机构,该设计容易导致虚接引起大电流的问题,因此设计了一款采用电气连锁机构的主通风机风门双电源自动切换装置。针对该装置,介绍其结构、工作原理和优点。该装置能够快速切换到备用电源,使风门快速动作,保证风机顺利开启,保证电源切换的安全性。
The fast cutting device of air gate power supply of main ventilator adopts mechanical chain mechanism,which can easily lead to the problem of high current caused by false connection.In view of this situation,a double power supply automatic switching device of main fan air door with electric chain mechanism is designed,and the structure,working principle and advantages of the device are introduced.The device can quickly switch to the standby power supply,make the air door move quickly,ensure the smooth opening of the fan,and ensure the safety of power switching.
