Low voltage combination switch
Low voltage combination switch
Mining explosion-proof and Intrinsically Safe Low-voltage Vacuum Combination Switch(hereinafter referred to as combination switch) is used in coal mines containing explosive gas and coal dust. It can logically control and protect the start-up or stop of 4 sets of three- phase squirrel-cage asynchronous motors under rated voltage 1140V (660V), AC 50Hz, and can change the phase sequence when the motor stops. The switch is especially applied to centralize monitoring of mining, transportation and other kinds of working faces with centralized dynamic loads. The switch has advantages like high automation level, convenient and intuitive man-machine dialogue, easy to networking, stable performance, sensitive protect, reliable operations, etc. It is a perfect upgrade product for mine digitization.
Wantai founded in 1998, now the net worth is 430 million yuan, focused on the research and development, production and sales of the Mining Explosion-Proof Equipment, High Voltage Combination Switchgear, and Miner' s Lampis also our main underground products.
Technical characteristics
•The shell of the combination switch is cuboids with quick-actuating closures structure. Reliable mechanical interlock and electric interlock system will ensure closure actuated after the power cut off. Each unit of the switch is modular structure in drawer plugged style
•The core control unit is Siemens PLC and has functions like programmable live and expandable points of output and input. Network communication is easy to establish with various functions such as telemetering, telecommunication, telecontrol, teleregulation called “4T”. Unattended working faces and concentrated detection and monitoring from ground control can be realized with functions above
•With display system in Chinese, and many control mode can be set like parameters settings, light running, sequential control and dual double-speed (including light double-speed, dual single-speed, and dual double-speed). The combination switch has functions of display and memories about running condition and failure mode. The efficiency of judging and removing breakdowns is improved greatly with friendly human-computer interface
