Automation Control System

(1) TK-FBZ2700 frequency conversion energy-saving control system adopts frequency converter to control the load of fans, pumps and belt conveyors, which is an ideal control method. When the motor runs at 80% of the rated speed, the rated power consumed is theoretically about 50% of the rated power; and the general inverter has an energy-saving PID function, which can easily realize closed-loop control and further improve energy-saving efficiency. Because the frequency converter can easily control the start-stop time and acceleration and deceleration current of the motor, it avoids the impact on the power grid when starting, reduces the equipment failure rate, eliminates equipment vibration, prolongs the service life of the equipment, and reduces the requirements for the power grid capacity. and reactive losses. 

(2) TKHVERT series high-voltage inverter system consists of phase-shifting transformer, power unit and control unit. TKHVERT series high-voltage inverters are high-high-voltage source inverters, and the main circuit switching device adopts imported IGBT or IGCT. Using advanced vector calculation method, it has the characteristics of high speed regulation accuracy, environmental protection, high efficiency and energy saving. This product has realized a number of technological innovations, such as the application of advanced technologies such as current automatic equalization level technology, series capacitor division voltage detection technology, time-domain optical communication anti-jamming system, bus node network voltage battery power supply, etc., which greatly improves the control of the system. sturdiness and reliability. This product can be directly used for power supply of ordinary standard high-voltage motors to realize variable-speed operation of high-voltage AC motors, with remarkable energy-saving effect, and has the characteristics of high safety level, strong reliability, simple operation and flexible control. Widely used in power system, metallurgy, coal, chemical industry, environmental protection, petroleum, water conservancy and other fields. 

(3) After half a century of research, operation and development, SF6 enclosed combined electrical appliances (GIS) have formed a complete series of products, and have shown unprecedented excellent performance in the power grid, which has contributed to the development of the power industry. Notable contribution. With the increasing demand for power supply quality, even a short power outage will have an unacceptable impact on modern industrial production and people's lives. Therefore, the monitoring of power supply equipment and the automation requirements for power grid management are becoming increasingly important. GIS realizes intelligent, Digital, real-time monitoring is imperative.

(4) GZG49 series DC power supply is mainly used in various power plants, hydropower stations and various substations in the power system. Power supply for emergency lighting.
