Brief introduction of zero line of power transformer
Careless maintenance and insulation damage
Breda Under normal conditions， different oil-based oils cannot be mixed. Under special circumstances， if it is necessary to use new oil of different grades， it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region， and then the oil mixing test should be carried out.
From the appearance， the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer， and only the shell can be seen for oil immersed transformer;
TulkaremAfter sampling， bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
What about oil immersed transformer fire?
In the case of dry-type transformer operation， there is more noise， and some even cause noise， which seriously endangers everyone"s no problem rest time and work. At this time， the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer"s network editor to simply understand it.
The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
The step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change， cutting off the load current will cause arc burning between circuit breakers， so the dry-type transformer shall be powered off during regulation. Therefore， it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.
In specific daily life， we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Potential developmentSound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window， ventilation and air exchange port and road surface， and apply sound insulation window， silencing cylinder， floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer，Breda Application of dry type transformer， and the distance shall not be less than m; At the angle with actual operation， a spacing of more than m shall be reserved; If metal fence is selected， the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
The whole process of hanging the core of dry-type transformer is more critical， and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore the hanging core of dry-type transformer should be carried out according to the above matters，Breda Automatic power transmission of transformer， so as to promote the safety of dry-type transformer!
Power transformers are also used for testing， 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， It is used to carry out insulation compressive strength test under required current for various electrical products，Breda Energy efficiency class I oil immersed transformer， electrical components and insulating raw materials.
Installation materialsWhen the full load test is carried out and everything is normal， the load can be connected.
According to statistics， to occupy the main global technical position， the transformer industry depends on two key data， commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage， China has been a powerful country in the production， manufacturing and application of dry-type transformers all over the world， common faults and impact. The work is diligent.
(IV) the transformer on the column shall be stable and firm resistance to short-circuit faults， and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.
