Product Introduction of Mine & Mobile Transformer Substation Explosion-proof Vacuum Switch
1. The advanced CPU technology is adopted in the protector,which has enhanced the independence of individual parts of function and the practicability of the system.Besides,the high- resolution A/D converter and and the detection method of single range measuring are also used in the device,which has greatly enhanced the accuracy of data collection.
2. It adopts blue-backlight LCD monitor,which enable data and all operations more intuitive.
3. It has the function which can detect and display a power factor and imbalance degree of each phase current as well as electricity consumption and real-time clock and so on.
4. It can provide protection in such cases as overload,short circuit,electricity leakage,insulation monitoring,overvoltage,undervoltage,three-phase imbalance etc.
5. It has the RS485 communication function, 2-999 pieces of protectors can be connected into network,accessing a local area network or the Internet through the couple.
