The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.Power transformers are used in all walks of lifePak Kobe,The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be far away (the distance can reach m, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor, open welding there are empty welding, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Basarabeasca,Seal oil leakageIn 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.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.

Operation of oil immersed transformerThe insulation of the through core anchor bolt clamping the iron core is damaged, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.equipment maintenance and the selected structures and connections are also different. Then,Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

How to reduce the failure of dry-type transformer?Quality inspection report,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.At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer,Pak KobeAll transformers, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.Power transformerPak Kobe,After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Before application, the sampling container shall be cleaned with vehicle gasoline, 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 ℃ drying oven. After refrigeration,Pak KobeModel and meaning of oil immersed transformer, the bottle cap shall be tightly closed and cannot be opened before application.& 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).
