There are many connection groups of dry-type transformers, 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.
Gaiogni.The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, CST = 0. One 750kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only 34%
After the test,Gaiogni500 kV dry type transformer, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.
.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, as the minute hand, refers to the position at 12 o'clock the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).
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 circuit
When the output power P2 of the transformer is equivalent to the input power P1, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, it is called copper loss.
What is the reason for the shutdown of power transformer?
Installation material list.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method 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, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
How much is the power transformer
The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe,GaiogniSpecification for dry type transformer grounding, and between the electromagnetic coil and the tap changer.
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer,GaiogniPrice list of transformer 3150kva, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
