SilversonThreeWhen the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
Manufacturing process and steps of dry-type transformer
Shinriro.Transformer
Before application, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.

Oil immersed transformer operation
Generally speaking,ShinriroDetailed structural drawing of dry-type transformer, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.
The transformer manufacturer will introduce the efficiency of the transformer to you
In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.
Interpretation and observation.Power transformer manufacturer
Seal oil leakage
The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.
Equipped with a temperature controller,ShinriroHow much is a 100 KVA power transformer, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice and then draw the oil sample.
It is understood that in China, transformers have experienced the whole process of replacing many series products such as sss11. As early as the middle and late 1980s, S7 Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb1300-73 and jb500 - Specifications operating in the power network at that time. Since the 19th century, urban power grids have been transformed all over the country,ShinriroState Grid transformer, and S9 series distribution transformers have been used to replace S7 Series. In recent years S13 and S15 commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is 50% - 80% less than that of S9 transformer.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
Shinriro.In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
