Main features
1)Dual power supply is used to ensure high reliability of power supply. When the main power supply fails, the standby power supply will be put into operation automatically.
2)PLC (programmable controller) as the central control unit, through real-time transformer oil temperature, load, oil flow relay, fan and pump protection state, running state of the cooler, the working state of the transformer (such as work or out of) working parameters, according to the need to put in or out of the corresponding number of cooling device, in order to achieve the ideal control effect.
