The distribution line control and protection for the low voltage side of the column on the main transformer are carried out. The HDl7SG switch is applied to the front side operation of the knife switch. The isolator does not need to open the box door, and the three-phase is divided and closed at the same time, and a low-voltage split phase reactive power compensation device is installed at the same time.
Can realize power measurement, measurement of current, voltage, power factor and other functions, the column outlet public variable operating condition for real-time monitoring, investigation power supply department, operation plan and equipment to develop the most economical and safe the capacity to provide a complete set of data, the successful development of the device, change a variety of the original product suspension type distribution box is insufficient, integrates multiple functions, convenient installation, operation and maintenance, reduce the labor intensity of workers and clean power, urban amenity, is conducive to the standardization of urban and rural public variable distribution standardized management.
