The description of S11-315 / 10 oil-immersed transformer

S11-315 / 10 oil-immersed transformer is based on summing up the design experience of S7 and S9 series transformers. It puts increasing product functions, improving product level, and improving product reliability in the first place. It uses new components, new materials and new structures. And improve the local structure, improve the product's electrical strength, mechanical strength and heat dissipation capacity. The use of corrugated mailbox, fully sealed structure to ensure that the transformer oil is completely isolated from the air that extend the life of the transformer oil and reduce the maintenance workload of the S11-315 / 10 oil-immersed transformer.

The advantages of S11-315 / 10 oil-immersed transformer

Corrugated oil tank, fully sealed structure, the corrugated plate wall has two functions of heat dissipation and expansion and contraction. The corrugated plate wall automatically expands and contracts with the change of temperature and load and S11-315 / 10 oil-immersed transformer.

oil temperature in the tank. More than 10,000 times, ensure that the S11-315 / 10 oil-immersed transformer oil is completely isolated from the air, and no maintenance is required during the life of the transformer.

Security protection

Fully sealed S11-315 / 10 oil-immersed transformer are equipped with pressure relief valves, which expands the application range of pressure relief valves and adds effective safety protection to the product.

Tap changer

The new double-sealed vertical switch is adopted to improve the sealing performance of the switch.

Strong parts in the box

The new type of lock nut is adopted to ensure that the body of the S11-315 / 10 oil-immersed transformer is not loosened during transportation.

The body of S11-315 / 10 oil-immersed transformer is connected with the lid.

The hanging belt structure is adopted to ensure that the body can "fall to the ground" and not cover the box.

Before installation, unscrew the top nut of the gas plug and check the oil level. If the oil level is less than 50mm below the top and add transformer oil of the same oil number to the top 30mm.

The features of S11-315 / 10 oil-immersed transformer

1. Except for copper cables, the low-voltage windings of S11-315 / 10 oil-immersed transformer generally use a cylindrical structure wound with copper foil. The high-voltage windings adopt a multilayer cylindrical structure to make the windings of the windings balanced and magnetic leakage Small, high mechanical strength and strong short-circuit resistance.

2. Iron cores and windings each adopt fastening measures. The height of the device, the low-voltage lead and other fastening parts are equipped with self-locking lock nuts.

3. the coil and core are vacuum-dried, and the S11-315 / 10 oil-immersed transformer oil is vacuum-filtered and oil-filled to reduce the moisture inside the transformer to a lower level.

4. The oil tank uses a corrugated sheet which has a breathing function to compensate for the volume change of oil caused by temperature changes. Therefore, this S11-315 / 10 oil-immersed transformer does not have an oil storage tank, which obviously reduces the height of the transformer.

5. Since the corrugated sheet replaces the oil storage tank, the S11-315 / 10 oil-immersed transformer oil is isolated from the outside, which effectively prevents the entry of oxygen and moisture and reduces the insulation performance.

6. According to the above five performances, it is ensured that oil-immersed transformers do not need oil change during normal operation, which greatly reduces the maintenance cost of the S11-315 / 10 oil-immersed transformer and prolongs the service life of the transformer.
