Corpus ChristiOn load voltage regulation of power transformerDemand is shrinking rapidly2022-03-11 23:59:28
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.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Corpus Christi, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications,Corpus ChristiTransformer 5000KVA price, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.Wiring mode of dry-type transformer:Grosseto,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?The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Due to poor sealing, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.Management DepartmentWhen the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Power transformerWhen 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.
When checking the hook core the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, insulation, etc. and deliver them after they are determined to be complete and reliable.Honest management,When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Transformer manufacturerNaturally, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.Corpus ChristiThere are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, 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.How much is the power transformerIn the case of dry-type transformer operation, there is more noise,Corpus ChristiHigh current transformer,Corpus ChristiPower transformer technology series, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.
