Main application

This product is suitable for use in the environment containing gas, coal dust and other explosive gases in underground coal mine. In the ac 1140V or 660V circuit, it can control the start, stop and double-speed switch of three-phase ac asynchronous motor or AC double-winding motor, and has the function of joint control.

 


Technical characteristics
1. Quick opening structure                                   
2. With local control and remote control function                                   
3. With reliable mechanical locking and electrical locking function

 

Functional features
• With the single-chip microcomputer as the control core, to achieve the dual circuit water level control required by various logic functions
• Real time display of various parameters of switch operation, with fault record and query functions
• Water level control function and independent use and free selection function
• When the water level rises rapidly, it cannot control the rising water level in time
• It has the function that 1# loop stops in the process of drainage, and 2# loop automatically puts into drainage work 
• Independent dual circuit drainage control function. Through the water level to realize the double circuit switch automatic start, stop function
• It can be used as a completely independent double-circuit switch
• Rs-485 communication function, convenient for remote control and monitoring
