Analysis of common faults of oil immersed transformer:Oil leakage at looper flangeCuritiba,Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.When the full load test is carried out and everything is normal, the load can be connected.aqaba ,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,CuritibaParameters of 1250kva oil immersed transformer, and D (or D) is triangular wiring.Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, voltage transformation and blood pressure reduction must be carried out by the transformer.For the leakage that has already occurred, 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 goal of long-term treatment of leakage can be achieved.

The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.Word of mouth recommendation,Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;& ldquo; YN, D & rdquo;, 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).When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,CuritibaDry type transformer protection configuration, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,

Manufacturing process and steps of dry-type transformerretailer,The 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.How to maintain dry-type transformer?According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.CuritibaCauses of fire in power transformer& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
