AkbuWhich is a
AkbuQuotation In the case of dry-type transformer operation, there is more noise, 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.
Before no-load impulse closing, the transformer shall be placed for 24h and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Akbu.Two point grounding device of iron core caused by residual welding scar;
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module,AkbuOil immersed transformer gear, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
.What is the important role of power transformer
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.
Falling foreign matters and piercing
After no-load test run is normal for 24h, and the load shall be gradually increased from 25%, which can avoid the entry of solid dirt with a diameter of more than 12mm, 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, IP23 protective casing can be adopted which can avoid being equally divided with the above IP20 protective effects However, IP23 casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.
Before and after sampling,AkbuPrice of dry-type transformer 2500, clean the periphery of the sampling port with clean or hairless linen.
recommend.Wiring mode of dry-type transformer:
Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.
Analysis of common faults of oil immersed transformer:
Manufacturing process and steps of dry-type transformer
device management.Oil leakage of cast iron parts
The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than 150kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds 150kV, epoxy resin adhesive shall be used to pour dry-type transformers.
