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 Lamp is also our main underground products.

01. The compound switch is connected by thyristor and magnetic hold relay, Realization of Voltage Zero-Crossing and current Zero-Crossing, Make the compound switch have the advantage of ZCS switching on and off at the moment of switch on and off, The effect of no inrush current and no harmonic injection can be achieved. 02. Microelectronic hardware and software control and intelligent control of silicon controlled , Operation of relays and input power and loads,so it has perfect protection function. The Intelligent Control Technology with traps and the latest Electronic components, Compared with similar products, High performance advantage in inrush current and safety reliability. 03. Photoelectric isolation of input signal and compound switch: Strong anti-interference ability, safe and reliable work. 04. Power consumption is little: Due to the use of magnetic retention relays, The control device only consumes electricity at the moment of switching, At ordinary times no electricity is consumed, Due to low contact resistance of magnetic hold relay,and thus it doesnâ??t heat, In this way, the cost is reduced without adding heat sink or fan. Completely avoiding SCR burning, At the same time, it does not cause harm to other electrical appliances running on the same machine, which really achieves the purpose of saving energy and reducing consumption.
