Factory dry type transformer SCB10-500KVA do what inspection? 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 function, the completion of its various parts of the advantage is able to. Dry transformer also regularly do a "physical examination", found that there is something wrong with the "body" to focus on solving these problems. Dry transformer in the "physical examination" time must do these aspects, and is to do several "physical examination" every month, so that 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 the dry-type transformer is an alternating flux, in order to reduce the eddy current loss, the core of the dry-type transformer is made of electrical steel sheets.
Windings: according to the winding in the core of the placement 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 effect of dry transformer oil is twofold: 1, can enhance insulation; 2, the core and winding because of the loss of heat, heat transfer to the surface of the iron box through the convection effect of the oil after heating, and then from the surface of the iron box scattered to all around.
Oil tank: the effect of the oil tank is to reduce the touch area between the oil and the air to reduce the oxidation rate of the oil and the moisture intrusion into the dry type 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 view, 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 complete the dry transformer operation better guarantee!
