AC Series Compensation De-icing Device
AC Series Compensation De-icing Device

General
     The device includes the following equipments: high voltage series capacitors, series reactor, discharge coil, zinc oxide arrester, grounding switch, electric display device, connect wires, post insulators, installed framework;
Its working principle: The devices is connected with line required ice melting in series, to adjust its capacitance to match line inductance and make the line current up to the melting of ice required current, through power supply of interval outline at 10kV substation, after running of certain time, the wires heat will melt the ice build-up online on the road, to play the role of melting ice.
Main Features
Simple structure, low cost;
Capacitance adjustment range large , the wiring simple, flexible;
Because of circuit inductance to compensate, making the ice melting power consumption efficiency to achieve energy saving purposes;
Direct power supply with a 10kV substation, the program advanced;
Capacitor lying down layout, small size;
