Large-Capacity Oil Transformers
Comprising an iron core, coils, a regulating switch, an oil container, and utilizing insulating oil as its fundamental insulation material, the oil-immersed power transformer is an electrical apparatus designed for voltage conversion and AC power transmission. It distinguishes itself with its compact size, cost-effectiveness, and exceptional weather tolerance.
Product Details：Large-Capacity Oil Transformers
The primary merits of oil-immersed transformers lie in their remarkable efficiency and energy conservation capabilities, coupled with superior insulation properties and dependability. The insulating oil within functions admirably, efficiently isolating the windings, guarding against arcing, discharging, and other malfunctions, while regulating temperature to prevent overheating and thereby enhancing the transformer's lifespan.

1. Transformer oil change and drying treatment
（1）Transformer idle for too long, running time is too long or the influence of other natural and man-made factors, resulting in transformer insulation degradation, internal water or oil degradation and other phenomena, at this time the transformer must be oil change and drying treatment.
（2）Transformer oil change: first lifting out the body, drain the dirty oil and wash the oil tank, such as body oil should also be flushed. To be body drying after injection of new oil, replacement of all oil-resistant rubber seals. Only after the test is qualified can it be connected to the network operation.
（3）Transformer drying treatment: body drying methods. Users can use zero phase sequence drying method, eddy current drying method, short circuit drying method, oven drying method.
（4）For larger capacity and voltage of 35 kV pole transformer, it is best to send the manufacturer for vacuum drying. This can ensure that the transformer insulation dry thoroughly, but also does not make the insulation aging.
2. Installation Requirements
Designated safety measures:
(1) Prevent personal electric shock and accidents such as falls.
(2) Prevent insulation from overheating.
(3) Prevent fire.
(4) Prevent something from falling into the tank.
(5) Prevent damage to accessories.
(6) Prevent the transformer from tipping over.
Formulate technical measures:
(1) Prevent the transformer core from getting wet.
(2) How to ensure that the connection parts are in good contact.
(3) Sealing of each part should be good and no oil leakage.
(4) How to ensure transformer insulation and oil insulation.
