How much is the power transformerIf 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.Braslow,The secondary inductive equipment of the distribution station (such as transformer, voltage transformer,BraslowMaintenance specification for box type transformer, AC etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz 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.Causes of fire in power transformerMont-Dore,Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.Dry type transformer manufacturerOil leakage of bolt or pipe external thread

Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, riser, coupling and oil storage tank cabinet, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process,BraslowInsulating oil of oil type transformer, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.In order to promote the use of energy-saving transformers, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as , providing subsidies of - yuan / KVA for energy-saving transformers.In 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.Inspection standard,In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).After 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.

The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.Welcome calls ,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, 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.It can be seen from the above that from the perspective of power saving,BraslowWhat are the components of an oil immersed transformer, in some cases, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo;, Even less than & ldquo; Great Lars, little dragons & rdquo;, Therefore, the loss of transformer full load and load must be considered in the calculation, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: . The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, the operating load and rated capacity of the transformer . Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, the formula is reduced The load index is the load index when the transformer operation loss is small and the rate is large, and the rate is large when the specific copper loss is equivalent to iron loss.Power transformerBraslow,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?Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.Power transformer manufacturer
