What has changed in the S9-M series of oil-immersed power transformers?

S9-M series fully sealed Satons oil immersed power transformer is summed up S7,S9 series transformer product design experience, based on the increase of product features, improve product level, improve product reliability in the first place, the use of new components, new materials, new structure and improve the local structure, improve the electrical strength of the product, mechanical performance and heat dissipation capacity, the use of corrugated oil tank, fully sealed structure, to ensure that the transformer oil and air completely isolated, extend the service life of the transformer, reduce the maintenance workload of the transformer. Product Features Editor Podcast.

transformer oil tank: using corrugated oil tank, fully sealed structure, corrugated plate wall with heat dissipation and expansion of two functions, corrugated plate wall with the temperature change, the size of the load, the oil tank transformer oil temperature and automatic expansion, corrugated plate wall expansion function is greater than 10,000 times to ensure that the transformer oil and air completely isolated, in the transformer life without maintenance.

safety protection: fully sealed transformers are retrofitted with pressure release valve, expanding the scope of application of the pressure release valve, so that the product increases the effective safety protection.

Tap changer: New type of double-sealed vertical switch is adopted to improve the sealing performance of the switch.

Box solid parts: the use of new relaxation fall curtain, to ensure that the transformer in the process of transportation body tightening does not loosen.

The apparatus body and box cover connection: using the hanging plate with structure, to ensure that the transformer body can fall to the ground and not top box cover.

Before installation, unscrew the top nut of the gas plug, check the oil level, such as the oil level below 50mm must be filled with the same oil number of transformer oil to the top 30mm can be.
