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, the bottle cap shall be tightly closed and cannot be opened before application.The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.San Coloma de gramenet, apart from the application of the Finance Bureau the industry has been trying to formulate and upgrade transformer commodities according to the specifications, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory,San Coloma de gramenetScb13 dry type transformer with secondary energy efficiency, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.LiuyangWhen the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, 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,After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Step up process of dry-type transformer?In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg, and the oil sample for simplified experiment shall not be less than kg.Test conclusion,San Coloma de gramenetS13 oil immersed transformer,Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.

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 %.system, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time,San Coloma de gramenet10kV oil immersed distribution transformer, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.What about oil immersed transformer fire?San Coloma de gramenet,Oil immersed transformer companyWhen the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.The noise of dry-type transformer comes from
