Product Description

Explosion-proof and intrinsically safe dual power vacuum electromagnetic starter for mine fan ventilator

Main application

This device is suitable for containing explosive gas (methane) and coal mine, based on the current coal mine design and manufacture of continuous ventilation safety requirements, its high-performance single machine as control core to real-time monitor the running state of the controller and fault processing, realize the host, for machine running state switch each other, in 50Hz ac voltage 660V or 1140V three-phase neutral point grounding line, to control the continuous tunneling ventilation in the working face, a double fan and double power supply all the control functions.

Technical characteristics

• Rated working voltage: 1140V or 660V
• Rated working frequency: 50HZ
• Rated operating current:
Single circuit 30A (type 30), single circuit 60A (type 60)
Single circuit 80A (type 80), single circuit 120A (type 120)

                                       
Functional features

• It has all the control functions required for automatic switching between the main fan and the standby fan
• SCM program control, large screen Chinese display, menu structure operation, with fault query, fault record the specific time function
• It has the function of mutual delay switching between host and standby machine, and the switching time can be adjusted according to the actual needs (0-250s)
• With dual fan dual power supply all control functions
• With RS-485 communication function, can easily achieve remote monitoring and control
• With short circuit, overload, leakage blocking, break equal protection function.
