How to choose a vacuum transformer oil purifier?

Of course firstly, we need to choose the vacuum transformer oil purifier. Vacuum transformer oil purifier as the transformer oil filtration system for filtering the old and new transformer oil.

Why do we need to purify the transformer oil?

A. If the transformer oil is not degassed before injection transformer, when the transformer put into operation, since the internal temperature and pressure changes of the transformer body, the gas dissolved in the transformer oil is gradually released, or the surface of the solid transformer oil bubbles will appear, because of the dielectric constant of the bubbles is much larger than the transformer oil, which breakdown voltage below the breakdown voltage of the insulating oil, the bubbles easier partial discharge occurs in the operation, frequent discharge will continue to damage the transformer insulation. If the dissolved gases in the transformer oil reaches a certain level, it will release large volumes of gas, these gases will not only make the operation of the Buchholz relay air bridge is formed, and may be provided along the direction of the electric field, causing the transformer internal breakdown, it is a serious threat for operation of the transformer. The gas contained in the transformer oil, and acetylene is a special gas, acetylene generate at 700 degrees.

B. more under high energy discharge to generate, so become an important basis for determining transformer internal spark discharge or arcing fault, since the insulating the oil in the refining process produces acetylene gas, if don`t degass before inject the oil to transformer, it will seriously affect the discharge of transformer internal fault judgment. So we suggest use our high vacuum transformer oilpurifier to do degass process.

How to choose?

1. For degassing, dewatering, we need to choose the vacuum oil purifier

It is better you choose the high vacuum, low pressure vacuum oil purifier.

Because the transformer oil is only with moisture, our ZYD-I,ZYD-II can guaranty the final oil achieve 3 ppm

2. For removing the particles.

3. ZANYO oil purifier can guaranty the fine filter achieve 1 micro.
