In recent years, the products have been adopted by many domestic power plants. I plant technology sector according to user requirements and site usage, to improve constantly, now fully meet the operational requirements of the scene. 1, using the XMTX-3000 type digital regulator controller set temperature setting, display, output power setting, on a full-scale, low alarm interface, DC 4-20mA temperature transmitter signal (corresponding to a temperature of full scale) interface. Three-phase thyristor trigger output signal and other functions into one, improve the reliability of the automatic control system. 2, the entire device designed, made multiple ZRMI-H-type hopper temperature control units can be directly carried out independently of each hopper automatic temperature control. Each chip hopper and can display their work status. 3, each supporting MIHC hopper-type mineral insulated heating cable, the total power 8-20KW, control for three-phase four-wire, three-phase power to protect the balance. 4, the control of all heaters are used for the implementation of SCR components to ensure reliable operation of the heater. SCR regulator by XMTX-3000 controller to control. According hopper temperature requirements, can provide zero phase shift or SCR trigger pulses to achieve the purpose of adjusting the heater power.
