Oil immersed power transformers are mainly used in 10kV,630kVA below the station area, to achieve automatic volume regulation, automatic voltage regulation, distribution monitoring and wireless "four remote" functions.
Product/performance characteristics
Automatic voltage regulation function:
When the voltage fluctuation is caused by the unstable load of the user or the line, the transformer can automatically adjust the voltage level, improve the power supply quality, extend the life of the equipment, and solve the problem of low voltage pass rate during the peak and valley period of the distribution network load.
Automatic volume adjustment function:
Automatically adjust the capacity according to the load size, so that the transformer automatically runs in the small-capacity file during the load trough period, the no-load loss is greatly reduced in light load, the no-load active power loss in small capacity is less than 1/3 of that in large capacity, and the reactive power demand is 1/10 of that in large capacity, and the energy-saving effect is remarkable.
Power distribution monitoring and wireless "four remote" :
WIFI, GSM, GPRS a variety of communication methods, with real-time monitoring, remote control transformer operating status, view and modify the set value and other functions, to achieve the distribution network station area automation control.
Maintenance free design:
The service life is maintenance-free, allowing users to enjoy the convenience of new technology.
