KobretiPrice of 800 KVA dry type box transformerRelease signal

The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.Oil immersed transformer companyKobreti,KobretiTransformer voltage,The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, offset, cracking, loosening,KobretiWeight table of oil immersed transformer, ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore,The hanging core of dry-type transformer is a vital partIt will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.The noise of dry-type transformer comes from

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?The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV,When using the oil sample of the power transformer in operation,KobretiThree phase dry AC transformer, 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, and then take the oil sample.What is the reason for the shutdown of power transformer?Avoid the load operation of power transformer: if the load operation is long-term it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction chemical enterprises and factories.Quality Assurance,The method and whole process of taking oil sample of power transformer are as follows:The transformer manufacturer will introduce the efficiency of the transformer to youFor kVA power engineering transformer, plastic parts are selected in the middle of iron core clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.Kobreti,Oil leakage of heat pipe radiatorThe insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.How to reduce the failure of dry-type transformer?
