Transformer manufacturers generally adopt IP protective casing， which can avoid the entry of solid dirt with a diameter of more than mm， rats snakes， birds and other animals cats， resulting in vicious common faults such as short-circuit fault and power failure， and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors，Products Show IP protective casing can be adopted，PaziciaScb13-1600kva dry type transformerProduct desciption which can avoid being equally divided with the above IP protective effects However， IP casing will reduce the refrigeration capacity of the transformer， so pay attention to the reduction of its operating volume.
8There is a magnetic induction line crossing in the transformer core， which will cause induced electromotive force on the plan perpendicular to the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex， it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.

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.
NManisaThis is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
MaThe selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV， class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV， epoxy resin adhesive shall be used to pour dry-type transformers.
How to maintain dry-type transformer?
The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication，Products Show and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be transmitted to a distance (the distance can reach m， the electronic computer can be equipped with an electronic computer socket， an intelligent transmitter， and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor， so as to further improve the stability of the temperature maintenance system software.

dNThere is a magnetic induction line crossing in the transformer core， which will cause induced electromotive force on the plan perpendicular to the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex， it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.
In order to better avoid transmission overvoltage damage， a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.
The top and middle of the transformer oil tank， the flange plate， barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage，Products Show resulting in insulation damage.
Good reputationvFor oil transformer oil replenishment， unused transformer oil conforming to the new standard should be selected first. In addition，PaziciaScb13-1600kva dry type transformerProduct desciption the oil with the same basic， same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %， there is generally no problem. However， if there is more new remaining oil， oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain， in some cases， transformers & ldquo; A small horse pulls a small car & rdquo; Cant compare with & ldquo; Middle car & rdquo;， Even less than & ldquo; Great Lars，Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory Therefore， the loss of transformer full load and load must be considered in the calculation， and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: . The transformer load rate and power saving will be brought into the formula: the load index of the transformer， that is， the operating load and rated capacity of the transformer . Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P， and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer， that is， the formula: Subtraction formula is used to calculate the detailed formula for saving transformer output power: when the transformer operation loss is small and the rate is large， the load index is the load index， and when the specific copper loss is equivalent to iron loss， the rate is large.

bJThe transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment， the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer， it can operate immediately. However， for the general application environment
