Detailed Description
11kV - 1250kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution
Introduction
As per IEC60076 standard required, cast resin dry type transformer designed and manufactured byPearl Electric is welcomed in home and abroadwith features of low loss, artistic apearnce and compact size.
Scientific computing tools:
We use advanced electric, magnetic, thermal and mechanical computing software to calculate electro-magnetic field and magnetic flux leakage distributions, to analyzewave processes, and to select reliable insulation margin, thus to guarantee product reliability, enablelow noise level,clamp-proof,anti-fouling,high mechanical strength, flame resisting, strong overload ability and low partial discharge quality.
Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.
They are application to power transmission and distribution system,hotel,restaurant,commercial building,stadiums,chemical plants,stations,aiports,offshore drilling platforms,especially to heavy load centers and places with special fire protection requirements
# # Flameproof and no blast, no pollution, no venomous gas. Pearl has passed F1 test qualified by authority lab.
# High dampproot, Safe operation in 100% vilative humidity and other tough environment, no demoisture procedure is needed.
# Strong capacity of heat resistant.
# High over-load capability, running at 110% rated load, and 150% rated load at AF.
# Contour artistic and compact size, low cost for installing. Easy assembly.
# Performance and parameter conform to or excel the standards of GB, IEC or industry.
Storage
1 If temporary storage is necessary, the package should not be removed. If it is dismantled for acceptance inspection, repackaging should be made afterwards.
2 For storage for a longer period, the transformer should be stored in a warehouse, which is clean, dry, and free of chemical or corrosive materials.
3 The transformers should not be stacked.
4 For temporary outdoor storage, transformer should be put on wooden spacers at least 100mm high.
Inspection before Putting into Service
1 Check whether any fixed parts and connections have become loose. Re-tighten them if necessary.
2 Check whether all parts assembled after transport are in good condition and whether any alien objects have become lodged inside the transformer (especially the air ducts). If excessive dust has accumulated on the transformer, clear it in accordance with section 11.2.
3 Check whether the fans, temperature control devices and other accessories can function normally. Pay attention to the direction of rotation of the fans if there is a three-phase power source. Usually, air is blown up into the coil from the bottom. If not, the phase sequence of the power source should be changed. Refer to the cooling system instructions for details. For temperature control and indication system and other accessories, wire connection should be done according to the
instructions.
