兖州矿业(集团)公司鲍店煤矿根据井下直流供电特性及井下电机车运输特点,研制出井下架线电机车直流牵引网络监控系统,保证了直流牵引网络正常供电,且在故障后能快速复电,提高了电机车运输效率,处于国内领先水平。该系统在操作台可集中对现场各开关进行操作;与各分区开关间也可单独操作控制,互不闭锁;各开关现场也可就地操作。其特点如下:①采用新型霍尔元件传感器。实现对直流电流采样,信号经单片机处理后实现各种保护。开关具有开门闭锁功能,检
Yancheng Mining (Group) Company Baodian coal mine underground DC power supply characteristics and the characteristics of underground electric car transport, developed underground tram locomotive DC traction network monitoring system to ensure the normal DC traction network power supply, and in the failure to quickly re-electricity , Improve the efficiency of electric car transport, a leading domestic level. The system in the console can focus on the scene of the switch operation; and the partition switch can also be separate operation and control, mutual non-blocking; the switch site can also be operated locally. Its features are as follows: ① The new Hall element sensor. To achieve the DC current sampling, signal processing by the microcontroller to achieve a variety of protection. Switch with a door to open the lock function
