A kind of power engineering equipment that converts the 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 of electromagnetic energy in the whole process. Therefore,KutniaWhat are the components of an oil immersed transformer, the power consumption of the processing plant is all connected with kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.Oil leakage of porcelain pot and laminated glass oil level gaugeAmadora,Common problems of tap changer of power transformerThe insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Brief introduction of zero line of power transformer

The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.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, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only %After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal,Kutnia500 kV dry type transformer, and the transformer will turn to all normal operation.Test results,Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.Loose core screw

(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.Highly recommended,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.It can be seen from the above that from the perspective of power saving, in some cases, Even less than & ldquo; Great Lars,KutniaAdvantages of oil immersed transformer, little dragons & rdquo;, 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 is reduced The load index is the load index when the transformer operation loss is small and the rate is large, and the rate is large when the specific copper loss is equivalent to iron loss.Solenoid insulation deteriorationKutnia,The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
