Generator-transformer protection products

Table 1 Main technical data rating detection auxiliary signal contact capacity AC voltage AC current frequency protection auxiliary DC power supply (V) AC power supply allowable electric power H change consumption voltage is not greater than 1 or 5 250V, current is not greater than (two-sided screen) WFB-1 generator-transformer protection device adopts Intel Corporation's MCA-96 series 80C196 single-chip microcomputer to form multi-CPU parallel working structure. It is suitable for the protection of large generator-transformer sets. It is also suitable for the complete protection of various types of large, medium and small units and step-down transformers below 500kV.

It is composed of three or four XC-20/12 chassis and a printer attached. It is composed of multiple plug-ins, and can be installed in one set or supplied separately with other devices.
