Industrial Oil-Cooled Transformers
Oil-immersed power transformer is an electrical appliance that adopts insulating oil as insulating medium and is composed of iron core, coil, regulator switch, oil tank, etc. to change voltage and transmit AC energy, featuring small volume, cheap price and strong weather resistance.
Product Details：Industrial Oil-Cooled Transformers
Chief among the advantages of oil-immersed transformers are their efficiency in energy usage and savings, accompanied by excellent insulation qualities and reliability. The insulating oil within the transformer acts as a robust barrier, efficiently isolating the windings and preventing the occurrence of arcs, discharges, and other malfunctions. It also regulates temperatures, averting overheating and thereby prolonging the transformer's service life.

1. Pre-installation preparation
Work time quota: (according to the national quota standard) the comprehensive work days required for the installation of the body is 21 work days.
Work includes: unpacking inspection, the body in place, body inspection, casing, oil pillow and radiator cleaning, etc., oil column test, accessory installation, pad iron and stop wheel production and installation, supplementary column and installation of the overall sealing test, grounding, fill paint, etc..
Transformer in the installation process whether need to dry, inspection and judgment to determine, need to dry, with the iron loss drying method when drying after the work days required for 20 days, oil filtration work days required for 3.38 work days / ton.
Debugging work days required to be calculated separately.
2. Prevention of oil leakage:
Oil-immersed transformer in the tank is filled with transformer oil, the assembly relies on fasteners on the oil-resistant rubber components pressurized and sealed. Poor sealing is the main reason for transformer oil leakage, so in the maintenance and repair should pay special attention.
Whether the small bolt after vibration and loose, if loose should be tightened solid, tighten the degree should be appropriate, and should be consistent everywhere. Whether the rubber is broken or deformed seriously. This can be updated rubber parts, replacement should pay attention to its model specifications are consistent, and keep the sealing surface clean.
