FitabriWhat is
Krasnoyarsk220The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
Fitabri.Precautions for trial operation of power transformer manufacturers
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?
.Loose core screw
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
The manufacturing process of dry-type transformer is very process,FitabriOil immersed transformer gear, and must be technically as a certain pillar. Only in that way,FitabriOn load voltage regulation of power transformer, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core,FitabriOil immersed 1000 KVA transformer, which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, and only the shell can be seen for oil immersed transformer;
technical service.Note: in the whole process of safety patrol inspection the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.
Manufacturing process and steps of dry-type transformer
Falling foreign matters and piercing
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults common faults and impact. The work is diligent.
Marketing Department.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, power off immediately for maintenance.
Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.
