SC Seties Flameproof Dry Type Transformer Good Heat Dissipation
Characteristic advantages and explanation of transformer material
1. the product has good heat dissipation and insulation
performance, and can operate normally under the harsh environment
conditions such as high temperature, high humidity and so on.
2. design according to the user's special performance requirements.
A. transformer core is made of high quality and high conductivity
of Japan imported cold rolled silicon steel sheet, using the
longitudinal "staircase" structure. Without burr, the iron core
should be pressed and dipped in layer insulation to reduce the loss
of eddy current. The magnetic flux density of the core is not
saturated when the transformer operates in negative connection. The
insulation level of
B. transformer is H, and the insulation is designed according to
continuous operation. When the transformer operates at the maximum
rated capacity, the maximum temperature rise should not exceed
C. is able to withstand short circuit capacity, and the relevant
provisions in the GB1094.5-85 standard should be implemented. The
transformer can withstand the three-phase short circuit of the low
pressure side outlet, the high voltage side bus is the short
circuit current supplied by the infinite power supply, the winding
does not deform, and the component does not damage. When a direct
short circuit occurs at the outlet of the low pressure side, the
core, coil and insulation of the transformer should not be damaged.
D. load capacity, natural air cooling (AN), under the specified
operating conditions, the transformer should output 100% of the
E. temperature rise limit, the temperature rise limit of mobile
substation should meet the requirements of GB6450-86.
Use of environmental conditions
1. altitude: 1000m;
2. environmental temperature: upper limit of 5 DEG C 40;
3. relative humidity: the relative humidity of air is not more than
95% (25 degrees C);
4. there is no strong turbulence, vibration, and the environment
that is not more than 15 degrees with the inclination of the
5. can be used in the air containing methane and coal dust at the
risk of explosion, but not enough to corrode metal and to destroy
the insulated gas and steam.
6. a place without dripping water or an environment with an anti
dripping water facility;
7. the waveform of the power supply voltage is similar to the sine
wave, and the three-phase power supply voltage is approximately
8. if the conditions are not in conformity with the above
conditions, we should negotiate with us.
When the user is buying, please make clear the following points
1. the basic models, specifications, capacity and quantity of the
2. the output and input voltage of the transformer;
3. the shape and size of the installation are for reference only.
If the required size needs to be changed, it must be explained at
the time of order.
