Q:What are the technical parameters of the transformer?
C, rated current (A): transformer in the rated capacity, allowing long-term through the current. D, no load loss (kW): when the rated frequency of the rated voltage applied to the end of a winding, the other winding open when the active power. And the core silicon steel sheet performance and manufacturing process, and the applied voltage. E, no-load current (%): When the transformer in the rated voltage under the secondary side of the load, the current through a winding, generally expressed as a percentage of the rated current. F, load loss (kW): the transformer secondary winding short circuit, in a winding rated tap position into the rated current, then the power consumption of the transformer. G, the impedance voltage (%): the secondary winding of the transformer short circuit, in a winding slowly increase the voltage, when the secondary winding short-circuit current equal to the rated value, then the voltage applied once the general. As a percentage. H, the number of phases and frequency: three-phase beginning to S said, single-phase start with D said. China's national standard frequency f is 50Hz. Foreign countries have 60Hz (such as the United States).
Q:Transformers, broken, how to repair
You can first check the insurance, if only insurance problems, you can short-term insurance; the other can buy a replacement of the same specifications, the coil can also be broken coil rewind.
Q:Can dry transformers and distribution cabinets be placed in the same room?
Yes. Dry-type transformers are usually placed in the room with a shell, low-voltage cabinet is with the dry-type transformers together. The general practice is to flush the cabinet. And then connect the transformer with the low voltage cabinet directly in the cabinet to go. Outside can not see the connection of copper.
Q:Transformer core
The core part of the transformer is the transformer is the exchange of AC voltage, current and impedance of the device, when the primary coil with AC current, the core (or core) will produce AC flux, the secondary coil induced voltage ( Or current). Sort by cooling: dry (self-cooling) transformers, oil immersion (self-cooling) transformers, fluoride (evaporative cooling) transformers. According to moisture-proof classification: open-type transformers, potting transformers, sealed transformers. According to the core or coil structure classification: core transformer (insert core, C core, ferrite core), shell transformer (insert core, C core, ferrite core), Ring transformers, metal foil transformers. According to the number of power supply categories: single-phase transformers, three-phase transformers, multi-phase transformers. By use classification: power transformers, voltage transformers, audio transformers, IF transformers, high-frequency transformers, pulse transformers.
Q:S11-1250kVA transformer oil capacity how much
S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.
Q:What is the transformer capacity ratio? Capacity than 100%.
Have not heard, you say is not the main transformer parallel run between the main transformer and the capacity and capacity of the ratio, or the meaning of such I made a change, you say is not: the transformer once measured capacity can be transferred to the secondary side or three times, such as three winding 50000KVA main transformer, 100/100/100, is the primary capacity can be all to the two Secondary use, you can also use all the three times, which is mainly and the main transformer winding, clip and so on factors
Q:How do you choose the public transformer capacity?
800X8 = 6400KW 6400KWX0.5 (use factor) = 3200KW + 50KW mall = 32500KW (full load operation) Choose three sets of 1000KVA transformer ,, 3000 (KVA) X0.9 (functional factors) = 2700KW · · · · · · · · · · · · · · · · · · · · · · · · · 315KVA transformer for 670 is too small ,,, 670X8 = 5360KW, 5360X0.5 = 2680KW 2680KW / 0.9 = 2977KVA Choose three sets of 1000 phase change
Q:What is the meaning of the Y D11 on the transformer?
Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).
Q:220 kv transformer capacity range,
I have seen the 220kV power transformer minimum 63MVA, the largest 250MVA, there is no such specification is not clear, it is estimated that small and small is not where to go, and then big is not where to go for reference The
Q:Transformer if the boost and buck current will change?
You here is actually a rated power problem, the transformer rated power is determined by the core size and winding diameter. Actual current X The actual output voltage can not be greater than the rated power otherwise there is a possibility of damage, which is the principle. If you are a constant load, the actual current will increase at the time of boost, and the actual current will decrease when it is lowered.   Disengaged the actual use of the transformer, the transformer as a boost when the input current must be greater than the output side of the current, the transformer as a buck when the input current must be less than the output side of the current.
