Electrical Flameproof Vacuum Insulated Switchgear Overload For Mine
Description:
KJZ2-1500/ 1140Z mine use FLP & I. S. Intelligent vacuum switchgear is suitable for underground mines containing methane mixture gas and with proneness of coal dust explosion. It controls start/ stop of main motor of belt conveyor, oil pump motor, cooling fan motor, loop winch motor and belt winder motor in power supply line of a. C. 50Hz, 1140V. It also provides protection for motors and power supply circuits. It has built-in CST control and display modules for control of soft starting of the belt conveyor. The switchgear has auxiliary power supplies of 127V and 220V for external illumination and controlling system.
Competitive Advantage:
DSP, CAN bus, self-adaptive detection, network interface, Chinese character LCD, fault detection and the outgoing cable connected by connector, built-in CST control and display modules.
