Several detection methods for installing transformer
4The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate， the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate， and then the iron loss is considered and the copper loss is ignored. In fact， for a certain load， the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer， so it consumes electromagnetic energy.

After the power transformer has been used for a long time，power transformer price 1000kva common faults of iron core will occur. Dont worry. Contact the transformer manufacturer，SeskatrebovaType of power transformerThree basic points of homework and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:
JTahekTransformer is a kind of power engineering equipment that converts working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering， it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss in the whole process of electromagnetic energy transmission. Therefore， which is converted into bottom voltage electromagnetic energy through transformer.
GaThe specific contents include eliminating the shortcomings found in the patrol inspection， cleaning the porcelain waterproof casing， removing and replacing the cracked or brittle leather pad， checking and tightening the nodes， replenishing the oil with less oil， checking and replacing the silica gel of the breathing mask， etc.
When the operating oil is mixed with different types of new oil or used for oil，power transformer price 1000kva in addition to the accurate measurement of the cold filter point of the mixed oil， it is also necessary to carry out high and low temperature test and sludge test and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor， the flange plate so it can be managed and used in a mixed manner.
The top and middle of the transformer oil tank， 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， resulting in insulation damage.
fDuring no-load test run， the transformer shall be connected with the working voltage from the switching power supply side， and then make the working voltage impulse closing.
GHow to select dry-type transformer
EAdministrationDry 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， but we must pay attention to many problems in the whole process of applying power transformer.

Create brilliancehMany people probably dont know much about the power distribution transformer manufacturers. In fact， the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period，power transformer price 1000kva you must pay attention to the following points. Whether there is abnormal sound， noise and vibration，SeskatrebovaType of power transformerThree basic points of homework whether there is abnormal smell such as coke smell， and whether there is discoloration caused by partial overheating. Ventilation is good. In addition， we should also pay attention to the following aspects.
GThe conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil， or between electromagnetic coil， iron yoke clamp and automobile oil tank wall. Therefore， it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength， i.e. insulation spacing.
With Vietnam and Malaysia， Chinas first UHV transmission experimental demonstration project，Power transformer price: 1000KVA, 33kV power transformer, 25kV power transformer, power transformer, oil immersed transformer, dry-type transformer factory China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world， occupying the main technical position of the industry development trend. In addition， it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
wNeratovicProtection mode for type selection of dry-type test transformer
nRTransformer manufacturers generally adopt IP protective casing， which can avoid the entry of solid dirt with a diameter of more than mm， rats， snakes， cats， birds and other animals， and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors， IP protective casing can be adopted， 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.
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.
