Mine Explosion-Proof Intrinsically Safe (Reversible)Vacuum Electromagnetic Starter

Product Introduction

This series of products are mainly used in coal mines and other explosive gas environments containing methane and coal dust mixtures in AC 50Hz voltage 1140V or 660V or 380V three-phase neutral point ungrounded lines to control the start and stop of three-phase asynchronous motors locally or remotely, and can perform reversing when the motor is stopped. (Models with N can control the forward and reverse rotation of three-phase asynchronous motors).

Technical advantages and features

• It has local control and intrinsically safe remote control functions; (models with N only have intrinsically safe remote control functions)
• It has water level automatic control function, automatically controlling the start and stop of the water pump according to the water level; (models without N have this function)
• It has menu-based operation structure, large-screen LCD Chinese display, fault query, fault record and corresponding fault alarm information functions, and can record the specific time when the fault occurs;
• It has functions such as smart screen integrated RS-485, Ethernet, Bluetooth, Wif, handheld terminal APP one-touch connection and LINUX operating system. RS-485 communication adopts Modbus RTU communication protocol format, Ethernet and Wi-Fi adopt Modbus TCP protocol format, which is convenient for networking and communication mode selection;
• It has reliable mechanical interlocking and electrical interlocking functions.

About Us

Wantai was established in 1998, and after more than 20 years of development, it now has six subsidiary companies: Huainan Wantai Electric Co.,Ltd., Shanghai Wantai Digital Technology Software Co.,Ltd., Wantai Power Business Department, Anhui Wantai Geophysical Technology Co.,Ltd., Huainan Zaochen Electromechanical Technology Co.,Ltd., and Huainan Wantai Electric Hefei Branch.Wha's more, it has set up four major research and development bases in Huainan, Hefei, Shanghai, and Xi'an.

The subsidiary companies under Wantai have a wide range of product development fields, each with its own focus.Among them,Wantai Electric is committed to the construction of smart mines,mainly focusing on the construction of integrated communication networks for all mine automation, 5G+4G+WiFi6+UWB, and intelligent transmission systems for permanent magnet motors, permanent magnet rollers,frequency converters, and other terminal equipment. Huainan Zaochen mainly provides mining environmental protection solutions for water supply,  power, and dust reduction. Wantai Power Business Department focuses on the smart grid, providing unmanned, big data energy-saving remote operation and maintenance systems, and intelligent high and low voltage complete electrical equipment. Wantai Geophysics provides customers with an integrated security solution based on microseismic monitoring and warning. It’s main technical   achievements include microseismic imaging,advanced detection during  excavation, as well as monitoring of mine gas, water hazards, mine tremors,slope stability, etc. The products are suitable for fields such as mines,petroleum,tunnels,and urban safety.

With the rapid development of science and technology, embracing change from the inside out is a long-term established idea for us. Currently,Wantai's business model is based on the times. The changes have begun to shift,and a product line management  plan has been launched, embarking on the path of intensive business development. Meanwhile, Wantai accelerates the promotion of international strategic layout.
