& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, 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.zebra,Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.When the transformer is out of phase,zebraMobile dry type transformer, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:Camajuani,Dry type transformer manufacturerWhat is the wiring mode of dry-type transformer?The switching power supply lacks one phase of power;

Oil immersed transformerWhen the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.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.Respect for customers,For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation,zebraDry type transformer scb10-100, it is very easy to cause fire accidents, damage to machinery and equipment, etc.Deterioration damage of transformer core insulationDry type transformer

The raw materials of Fushi blue can be used for bonding so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.Quality assurance,There are many connection groups of dry-type transformers,zebraOutline dimensions of oil immersed transformer, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.zebra,The hanging core of dry-type transformer is a vital partDry type transformer companyWhen sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles
