Voltum's Products
Profile
The Blower/cooling fan is mainly used for cooling and capacity
expnsion of dry transformers and cooling of electronic equipment.
power distribution cabinet.high and lower voltage switch gears and
other products. The cooling fans can increase the output power of
the dry transformer by 40-50%,it improves the carrying capacity of
the dry transformer and extend its life.
How It Works
When it applies for dry transformer,the fans are placed on both side of the lower part of the transofrmer coil .the air is directly blown into the high and lower voltage cooling channel of the transformer coil. the excellent heat dissipation ensures the transformer runs in good condition. The cooling fan operation,over heat alarm, over heat trip will be controlled by the temperature control system.

The Installation Adjustment Operation Of The WT Series Blower
The Blower should be placed on both side of the lower part of the transofrmer coil as below.
The Preferrence installation way for side blown.
The preferrence installation way for top blown.
T1ips:
1: The input power voltage, phase should meet the rated voltage and phase,the Blower for same transformer can connect to the power individually or parallel connected with other blowers the big power blower should install an intermediate relay.
2: After the fan is installed and powered on.please make sure the rotation direction of the fan meets the requirements of the fan rotation sign.
3: After long time transportation or long time storage, please check the insulation resistance is higher than 2 TΩ. however if it was affect by the humidity, then the insulation resistance should less than 0.5 TΩ
