Integrated measurement and control device for box transformer

In the design process of wind power station and photovoltaic power station, in order to reduce line loss, 10/35KV box-type booster station is generally configured beside the wind turbine or inverter. The HZ-D30-X box transformer protection measurement and control device can protect and remotely monitor the box transformer, fully realize the functions of "remote communication, remote measurement, remote control and remote adjustment" of the wind power box transformer, and realize the operation and management mode of "fewer people on duty" of wind power or photovoltaic projects.
