PisaElectronic high voltage transformer,

Noise solution of dry-type transformerDeterioration damage of transformer core insulationPisa,Transformer manufacturers generally adopt IP protective casing,PisaHow much is the European box transformer, which can avoid the entry of solid dirt with a diameter of more than mm, rats snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, which can avoid being equally divided with the above IP protective effects However, IP casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Page,When using the oil sample of the power transformer in operation it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Pursuit of excellence,Method and process of taking oil sample of power transformerMethod and process of taking oil sample of power transformerHigh voltage fuse of transformer breaks one phase;

The switching power supply lacks one phase of power;market,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 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.The transformer manufacturer will introduce the efficiency of the transformer to you& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line, refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is,PisaMaintenance system of oil immersed transformer, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).Pisa,If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.When the full load test is carried out and everything is normal, the load can be connected.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.
