Features of 1000KVA dry type transformer
1. Low loss, good power saving effect, bringing economic benefits in operation.2. Flame retardant, explosion-proof, pollution-free, maintenance-free, can be dispersed in the load center, reduce investment cost, save costs.
3. Local discharge power less than 10PC, coil no moisture absorption, no dust, high mechanical strength, good reliability.
4. Short circuit resistance and lightning impact resistance.
5. The shell is made of non-embroidered steel, cold plate and aluminum alloy. The type is divided into wind type and heat dissipation type.
6. Transformer can be equipped with temperature control and temperature display system according to user needs, and can be used with temperature control system.
1000KVA dry type transformer structure features:
1. The iron core
The 1000KVA dry transformer adopts high quality cold rolled grain oriented silicon steel sheet, and the iron core silicon steel sheet adopts 45 degree fully inclined joint, so that the magnetic flux passes along the joint direction of the silicon steel sheet.
2. The winding
The windings of 1000KVA dry transformer are as follows:
(1) spiral wound
(2) epoxy resin and quartz sand filling casting
(3) Glass fiber reinforced epoxy resin casting (i.e. thin insulating structure)
(4) multi-strand glass wire impregnated epoxy resin winding type
3. High voltage winding
1000KVA dry type transformer generally adopts multi-layer cylindrical or multi-layer segmented structure
4. Low voltage winding
1000KVA dry transformer generally adopts layer type or foil type structure.
1000KVA dry type transformer operating environment: indoor use
Normal operating conditions: the altitude does not exceed 1000m.
Ambient temperature ****** +40℃,
Minimum temperature -30℃,
Maximum annual mean temperature +20℃
(If it is inconsistent with the above conditions, detailed instructions can be made when ordering, and appropriate adjustments can be made according to the relevant provisions of the corresponding standards)
