The body of the dry transformer is relatively perfect, and various parts have different functions. For the dry type transformer should play out its different functions, to achieve the advantages of its various parts is possible. Dry transformer also regularly do a "physical examination", found that there is something wrong with the "body" to focus on solving these problems. Dry-type transformer in the "physical examination" must do these aspects, and is to do several "physical examination" every month, let the dry transformer operation and safety should be guaranteed.
Electronic dry-type transformer "body" analysis: power dry-type transformer is mainly composed of five parts 1, iron core; 2. Windings with insulation; 3, dry transformer oil; 4. Fuel tank; 5. Insulation bushing.
Iron core: the iron core of the dry transformer is the magnetic circuit of the dry transformer. Because the magnetic flux in the core of dry-type transformer is an alternating flux, in order to reduce the eddy current loss, the core of dry-type transformer is made of electrical steel sheet.
Windings: according to the winding in the core of the arrangement of classification, dry transformers can be divided into core and shell type two categories. The basic forms of dry transformer windings are the same core type and overlapping type. The iron-core dry transformer is commonly used with the same core type windings, and the iron-shell dry transformer is commonly used with the overlapping type windings.
Dry transformer oil: the role of dry transformer oil is double: 1, can enhance insulation; 2, the core and winding due to the loss of heat, heat transfer to the surface of the iron box through the convection action of the oil after heating, and then from the surface of the iron box scattered to the surrounding.
Oil tank: the role of the oil tank is to reduce the contact area between the oil and the air to reduce the oxidation rate of the oil and the water intrusion into the dry transformer;
Insulation bushing: Insulation bushing is composed of central conductive copper rod and porcelain bushing, etc.
The above is for the dry transformer on the body of a variety of inspections, is also the most important part of the "physical examination", the dry transformer "physical examination" is very important, should continue to deepen the process of perfection, to achieve a better guarantee of the dry transformer operation!
