| Abstract: | Mine low voltage feed switch is one of the key equipment for low-voltage power supply system.In this paper,a new mining system voltage feed switch was designed.This feed switch system used DSP as its control core,and the modbus communication protocol was used,with the CRC to ensure the accuracy of data transmission.The system test results show that: this system has the function of laekage latch,leakage protection,selective leakage protection,overload protection,short circuit protection,overvoltage and undervoltage protection,and it can greatly improve the system’s speed and power and the security of mine power supply system. |
| Keywords: | low voltage feed switch DSP Modbus protection |
