dry type transformer
Product has the following features:
1. Partial discharge value is low
GB1094.11 for dry type transformer under 1.3 Ur test voltage, partial discharge value is not more than 10 PCS qualified. Chi heng dry type transformer's unique structure and manufacturing process can be achieved
Under 1.3 Ur, partial discharge value is less than 1 PC; Even according to Siemens standard will rise to 2 UN test voltage value, the value of partial discharge is less than 5 PCS.
2. Lightning shock resistance ability
The initial distribution of lightning impulse voltage along the winding, affect the damage of the transformer winding insulation. Foil type winding turn-on voltage distribution is close to linear, therefore, chi heng dry type transformer
Have good lightning shock resistant capability.
3. The anti-short circuit ability
Is the reactance of the low voltage winding conductor foil width height, low voltage electric current match, according to the requirements of winding the ampere turns balance between high and low voltage winding axial force caused by short circuit is almost zero.
4. Good cracking resistance
Chi heng dry type transformer using the packing type resin and high and low voltage foil winding structure, epoxy resin with filler and the thermal expansion coefficient of conductor is more close to effectively prevent the coil craze. through
Trials show that tzu chi heng dry type transformer technology especially can satisfy the large range of low temperature, high humidity and temperature changes the use of occasions, and can meet the anti cracking for after a long run.
5. A good load performance
With quartz sand packing resin thermal conductivity is 2-3 times that of the pure resin. Equals the same capacity of transformer load loss, due to containing quartz sand packing of transformer winding heat
Thermal time constant of the capacitive, winding, transformer short-term overload capacity is strong.
6. Good environmental performance
My company dry type transformer has the free maintenance, moisture, wet and heat resistance, flame retardant and self-extinguishing properties. Under the arc of high temperature burning, does not produce any toxic gases. I change company dry
Transformer excellent flame retardant properties in combustion experiment confirmed.
My company dry type transformer has the very good environment adaptiveness, meet environmental levels of E2, corrosion resistance level C2, flame retardant grade requirements for use of the F1.
7. The noise is low
Dry type transformer I company has taken some special structure and design, make the noise level was lower than those of the noise in the national professional standard value 10 db (A) above
