Low Power Oil Immersed Transformers

Farady offers a wide range of low power oil immersed transformer such as generator duty, unit auxiliary transformers and multi winding transformers. All these step up transformers are customized for industrial plants and distribution substations. Our transformers are extremely versatile with robust construction and highest quality standards.

Oil immersed transformers - for very high power (MVA) and voltage

For very high power (MVA) and voltage, we provide oil immersed transformer. This solution guarantees the best possible resistance to dielectric stresses and, by using special heat exchangers, the elimination of losses, which allows the machine to cool. This type of oil type transformer is particularly suitable for energy distribution networks or installations subject to severe weather or environmental conditions. In view of the specificity of the applications, each product is customized to determine the characteristics that can beat satisfy the customer’s needs.

A winding temperature control function has immersed distribution transformers

A winding temperature control function has oil immersed distribution transformer, which is external casing, housing in the lumen of the transformer windings, characterized in that: the housing The top surface of the fixed outlet box has a wiring board, with a temperature sensor of the pole mounted transformer windings; wiring board terminal box comprises a case, the sealing plate Seal connected to the case top opening, opened outlet hole on the side panel case, open wire alignment hole on the bottom plate cassette; temperature sensor control line longitude positioning holes , outlet hole is connected to an external computer.

Farady oil immersed transformer Hanging Point Step

Before the oil immersed transformer hanging core work preparation:

⑴ tool material preparation: such as storage tank, oil filter, complete sets of wrenches, Dao Ben, oil-resistant rubber rope, white cloth, insulation cardboard.

⑵ equipment for the preparation of lifting: such as cranes, chain, lever hoist, tripod, wire rope, etc., if the chain, must be based on the height of the farady transformer and the weight of the hanger.

⑶ transformer oil treatment, take oil samples and test, do a good job in oil preparation, including oil filter paper.

⑷ do the preparation of oil pan, hand-core line.

The height of the hanger (h) shall not obstruct the lifting of the body.

So h = h1 + h2 + h3 + h4 + h5 test = h1 tank height h2 height of the device h3 rope height h4 pulley (or chain) minimum distance h5 standby height (300 ~ 500mm)

Dropping steps:

⑴ selected hanging core position, put the oil (placed under the broader market)

⑵ remove the explosion-proof tube, oil pillow, gas relay

⑶ remove the big cover bolts

⑷ use the balance iron will be hanging on the iron plate

⑸ check:

① core insulation

② core insulation

③ wear the core bolt insulation

④ tap switch contact insulation

⑤ high and low voltage lead

⑥ tank debris

⑦ heat pipe with or without clogging

⑧ telemetry insulation resistance

⑨ measure the DC resistance

⑹ all items after the inspection did not find the problem should be promptly loaded back, the iron back in the tank

⑺ strong cover bolts

⑻ install the removed accessories

⑼ into the qualified oil

⑽ static 6-10 hours after a full set of pressure test ⑾ site installation.
