There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.

What is the wiring mode of dry-type transformer?

Essen.Protection mode for type selection of dry-type test transformer

The switching power supply lacks one phase of power;

.Oil leakage of bolt or pipe external thread

When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.

Manufacturing process and steps of dry-type transformer

The voltage regulating tap changer is not in place or poor

The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.

It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.

Good reputation.Careless maintenance and insulation damage

Wiring mode of dry-type transformer:

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.

Essen.After sampling, the winding of oil immersed transformer is generally divided into multiple modules,EssenCharacteristics of dry type transformer,EssenPower transformer insulating oil test,EssenBasic knowledge of power transformer, and each module is replaced by an equivalent circuit and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
