KarinaPower transformer MSolve the problem of overcapacity

Dry type transformer companyAfter no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Karina,The secondary inductive equipment of the distribution station (such as transformer, voltage transformer, automobile relay, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz,Karina6kV distribution transformer, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.Noise pollution control and prevention measures of dry-type transformerCumanayagua,When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.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?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 installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.How to select dry-type transformerBefore no-load impulse closing, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.Recommendation and consultation,Oil leakage of bolt or pipe external threadThe 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.With the rapid development of society and the continuous development trend of computers, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.

High voltage fuse of transformer breaks one phase;A complete range of products,When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,Karina20kV power transformer,KarinaTransformer device, 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,Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large,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.The noise of dry-type transformer comes fromFrom the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
