Original product description
When electric power workers choose test transformers to conduct step-up tests, they often encounter the question of whether to choose oil-immersed type or inflatable type or dry type. Then the question arises, why is the same test transformer, there's oil, air and dry? This article answers your questions.
Because of the differences in the internal structure of the test transformers, they were divided into these three types of test transformers.
Their functions were all the same, but the internal insulation materials were just different, which resulted in the advantages and disadvantages of each of the three types of test transformers.
The oil-immersed test transformer, as its name implies, is an internal insulating oil used for ARC extinguishing, with many advantages, such as low cost, fast voltage boost, high voltage resistance, easy and cheap maintenance, etc.
, if it is damaged in the course of use, it can be taken to replace the copper core or the way to replace the insulation oil, so the cost of procurement and use are relatively low, but because the interior is loaded with insulation oil, therefore, the equipment is relatively heavy, not conducive to moving to outdoor use, and there are disadvantages such as oil pollution.
Inflatable test transformer, the internal use of SF6 gas for insulation arc, because it is inflatable, it has small size, light weight, clean and oil-free advantages, but if the internal gas escape, very difficult to repair, can only return to the factory to deal with the use of more trouble, and the cost of the equipment is relatively high, causing the price is naturally rising.
Dry-type test transformer, using the internal iron core plus epoxy casting technology manufacturing, one molding, there is no gas and do not use insulating oil, low cost, cheap, but large size, weight, at the same time, because it is one casting, if the internal damage, almost impossible to repair, the use of the process, the need for users to be extra careful, so the general small projects are more like to use the equipment.
As a whole, oil-immersed, gas-filled and dry-type transformers have their own advantages and disadvantages, to meet the different needs of different power workers .
