LSZ Three-phase integrated zero sequence current transformer can be applied to the power system of rated frequency 50Hz and rated voltage 12KV, installed in RMU and tri-phase bushing of pole-mounted switch, used for the measurement and protection of tri-phase current and zero sequence current, and also used for the measurement and protection of zero sequence current of multiple cable circuit.
The product is composed of tri-phase integrated plastic shell, tri-phase integrated zero sequence winding, A、C phase coil winding and epoxy resin casting. In the middle of plastic shell is the circular hole for tri-phase cable, in the lower part is the mounting hole for the fixed installation. The core and secondary winding all adopt high-quality epoxy resin casting in the flame-retardant plastic shell with the characteristics of moisture-proof, stable performance, simple structure and easy installation.
