MahendranagaHoThe 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 capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
Eagle fighter.Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.
When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation,Eagle fighterTransformer and current,Eagle fighter10kV dry type test transformer, power off immediately for maintenance.
.After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
The manufacturing process of dry-type transformer is very process, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
How much is the power transformer
The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However because of certain necessity,Eagle fighterFunction of oil immersed transformer, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
Analysis of common faults of oil immersed transformer:
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 2-5A / Min2.
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.
Respect for customers.High voltage fuse of transformer breaks one phase;
It can be seen from the above that from the perspective of power saving, 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: 3. The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, 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.
It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.
