& ldquo; YN, D & rdquo;,BurchiseDry type transformer 2500kVA, in which indicates that when the working voltage phasor of the primary side line, as the minute hand refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).Deterioration damage of transformer core insulationBurchise,Many people probably don't 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, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration,BurchiseDistribution 400 KVA transformer, 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.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.Zhuozhou ,BurchiseOverload capacity of oil immersed transformer,For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.The key reason for oil leakage is that there are defects in cast iron partsIn fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;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, the power consumption of the processing plant is all connected with kV switching power supply, 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, etc. and deliver them after they are determined to be complete and reliable.Quality inspection report,If the volume of power transformer is too small the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.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.Noise pollution control and prevention measures of dry-type transformer

The manufacturing process of dry-type transformer is very process, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?device management,Dry type transformer manufacturerHand touch method for transformer inspectionOil leakage at looper flangeBurchise,Seal oil leakageDeterioration damage of transformer core insulationThe switching power supply lacks one phase of power;
