Product Description
The device is used in coal mines containing explosive gas(methane) and coal dust and applicable to the power supply system with frequency AC 50Hz and voltage AC1140(660)V to realize controlling the start and stop of the belt conveyor and protecting the motor and the line. The device uses SIEMENS PLC as the control core and the 7-inch display embedded computer as the human-computer interaction interface. Support Profibus- DP, industrial Ethernet communication, networking with the ground control center to achieve centralized control. The starter is designed for belt conveyor, it assembles belt conveyor drive and protection, lighting, etc. So, the functions of start and stop control, automatic tension, coal control, gate motor control, tape machine control, deviation, over-temperature, slip and other basic protection and start warning and fault warning and so on can be realized.
•With the integration of belt main drive, tensioning winch control, the band-type brake control, roll machine control and 4.0KVA lighting power supply
•8 combination is composed of 2×400A soft start circuit and 4×120A + 2×80A direct start circuit (the total current is not more than 400A). 6 combination is composed of 2×400A soft start circuit and 2×120A reversible circuit + 2×80A direct start circuit. Each circuit has an independent monitoring and protecting unit
•With eight kinds of protecting sensors to realize the eight protection of conveyor. Having the intelligent para-position function of running deviation, stay and longitudinal tearing
•Having fault alarm function. Can also realize starting pre warning along the line and fault alarm equipped with the intrinsically safe type PA phone.
•Adopted the Siemens PLC as the control core. Very easy to achieve network centralized control, support profibus, industrial Ethernet communication
•Adopted embedded human-computer interaction interface, which can display the operation condition of each equipment, motor current, temperature, fault situation and inquire failure record, current and temperature curve
The pilot circuit of the device is intrinsically safe circuit, which can effectively prevent spontaneous starting accident caused by controlling short circuit or grounding
