How much is the power transformerThe input and output three-phase power lines shall be connected to phase a, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example transformer casing and its transformer point shall be connected to each other. At ordinary times, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Soyapango,The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.Dry type transformer factoryDet Udom,SoyapangoWhat do you think of box transformer meter,Oil leakage at looper flangeFor no-load impulse closing of transformer, pay attention to the following matters:Wiring mode of dry-type transformer:

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing,SoyapangoPower supply transformer, remove and replace the cracked or brittle leather pad, check and tighten the node replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitindex,SoyapangoLarge oil immersed transformer,Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

When the power transformer operates at full load, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Safety production,Oil leakage of cast iron partsHow to make up oil for oil immersed transformer?The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.Soyapango,The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.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;The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
