1, use
This device is suitable for frequency 50HZ, rated voltage of 3-35KV AC power system, to improve the power factor, adjust the network voltage, reduce line losses, enhancing output capacity of power transmission equipment, improve the quality of power supply.
TBB high voltage shunt capacitor complete sets of equipment for the framework of the structure, the capacitor can be used three-phase grouping or phase arrangement, when the voltage is more than 35KV, the capacitor device using three-phase phase separation.
One way of connection is mainly single star and double star connection. The larger capacity of the capacitor group can be used in double star connection.
One time equipment are: reactor, high voltage shunt capacitor, capacitor dedicated fuse, Zinc Oxide arrester, discharge coil, etc.. According to the requirements of the user can increase the isolation switch or grounding switch.
The reactor can be selected as required immersed reactor and dry reactors (indoor installation), air core reactor. The capacitor can be used dry or oil immersed capacitor.
Device with angle steel frame as a whole frame, hot galvanized, beautiful and strong, durable.
