Off-circuit Transformer Tap Changer

Name: Off-circuit Transformer Tap Changer
Brand: Ausin pipeline material&equipment co., ltd.
Availability: InStock

The off circuit tap changer transformer was designed together by the related factories organized by the Transformer Research Institute. The switch adopts a new structure, new material, and new technology, having the advantages of a reasonable structure, hand-feeling good, turning flexible, and reaching the designed place accurately, etc.

It is the updated product of the non-excitation transformer tap changer in our country at present, applying to the three-phase oil-immersed electrical power transformer with the frequency of 50Hz, 60Hz, the rated voltage of 10KV,35KV, the rated current of 63A,125A,250A, 400A. The off circuit tap changer transformer can be directly fixed on the box cover of the transformer, under the condition of non-excitation tapping, regulating, and changing.

Pressure relief valves play an important role in the protection of oil immersed electrical equipment, such as transformers, high voltage switch gears, capacitors and on load tap changers etc. This device can prevent the oil- immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation or rupture. Should a fault occur in in such electrical equipment, they are Instant aeneous vaporizes the oil causing extremely rapid build - up of gaseous pressure. If moaning this type of pressure relief device on the oil tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.

The tap changer with current of 63Aapplies to the box-cover of the transformer of 5-8mm.
The tap changer with current of 125Aapplies to the box-cover of the transformer of 6- 10mm.
The tap changer with current of 250Aapplies to the box-cover of the transformer of 8-12mm.
If the customer has a special requirement, please give an explanation when ordering.

This kind of switch applies to the single-phase, three-phase, combination oil-immersed transformer of electrical power with frequency of 50HZ,60HZ, rated voltage of 10KV,35KV, rated current of 30A-250A; the voltage-regulating places are central part, neutral point, can be directly fixed on the box-cover of the transformer, under the non-excitation condition regulating and changing.

Cage non-excitation tap changer for American BOX-Type Transformer

These switches are mainly applicable to the combined (bedding type) transformer, which is called American Box-Type transformer. Only under non excitation condition, can it be used to carry out the regulating function of the primary coil voltage tapping, regulating and changing.

Double-bridge crossing connection, series-parallel, connection positive-negative voltage-regulating cage tap changers.

As a special element on hermetic transformers, YWL oil Level gauge is adopted thread connection instead of flange joint, which has advantages of reliable sealing property, easy to use, connecting quickly and better working efficiency.

Place on the upper part top of a transformer, YWL oil Level Gauge can indicate oil level in transformers with a blue- red buoy. Blue means Ok and when the red buoy appears, you should add Oil in transformers as soon as possible. Changing of oil level in transformers can be easily watched by a 360 window on YWL oil Level Gauge.

In addition, owing to thread connection, the rubber sealing ring is pressed in a reasonable range so that it is durable with safe reliability (adopted seamless steel tube or AI- Alloy tube), good looking (electrostatic spray painting), YW LOil Level Gauge also can be used as oiling connector, pressure relief valve and vacuums pressure gauge, etc.
