Q:Transformer cooling method AN stands for what
The cooling mode of the transformer is determined by the cooling medium and the circulation method. Since the oil-immersed transformer is also divided into the internal cooling mode of the tank and the external cooling mode of the tank, the cooling mode of the oil-immersed transformer is represented by four letters.   The first letter: the cooling medium in contact with the winding. O -------- mineral oil or ignition of more than 300 ℃ of insulating liquid; K -------- Insulation liquid with ignition point greater than 300 ℃; L -------- ignition can not be measured insulation liquid;   The second letter: the way the internal cooling medium is circulated. N -------- The oil flow flowing through the cooling equipment and the windings is a natural thermal convection cycle; F -------- The oil flow in the cooling equipment is forced to circulate and the oil flow flowing through the windings is the thermal convection cycle; D -------- The oil flow in the cooling equipment is forced to circulate, at least in the main winding oil flow is forced to guide the cycle;   Third letter: external cooling medium. A -------- air; W -------- water;   The fourth letter: the way the external cooling medium is circulated. N -------- natural convection; F -------- Forced circulation (fan, pump, etc.).   Therefore, the transformer cooling method AN represents the air convection cooling method.
Q:What is the transformer absorption ratio (R60 / R15)
Generally, the absorption ratio should be greater than or equal to 1.3 as the absorption ratio is acceptable.
Q:How much capacity the transformer has
For power transformers, there are 10 20 30 40 50 63 80 100 125 160 200 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 6300, etc. kVA.
Q:Transformer winding maximum temperature at?
National standard (oil-immersed transformer) the top of the oil temperature is generally adjusted at 85 ℃, if more than 85 ℃, to analyze the reasons: 1, if it is because the room temperature is too high, heavy load and other slowly rising, you can continue to run more than 85 ℃, but The maximum temperature can not exceed 95 ℃ (when the transformer core core or winding is 105 ℃, will seriously damage the insulation, shorten the life or burn the transformer); 2, the transformer running at 85 ℃, the transformer oil temperature and room temperature difference can not exceed 55 ℃, if it is over, may be a serious overload, the voltage is too low, the current is too large, internal failure, etc., continue to run will seriously damage the insulation, shorten the life or burn the transformer.
Q:50KVA transformer maximum load is how much?
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). The circuit symbol is commonly used as the beginning of the number.
Q:Two different impedance of the transformer, parallel load how to allocate?
Two parallel operating impedance must be equal, because the parallel operation of the transformer load is inversely proportional to the impedance voltage distribution, if the impedance voltage difference is too large, will lead to the occurrence of excessive impedance voltage overload phenomenon is recommended to allow the difference is generally not more than 10% , The general formula is St1 = S * Zt2 / (Zt1 + Zt2), St2 = S * Zt1 / (Zt1 + Zt2), where Zt is the per unit value, Zt = Uk% * Sd / 100Sn Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:My device has 50KW should be used with much transformer
On the use of 50KVA transformer on the line, because your device will not appear at the same time the maximum power.
Q:What is the rated current of the 80KVA transformer?
Rated current formula: I = P / 1.732 × U = 80000 / 1.732 × 380 ≈ 122 (A) (Current contains active and reactive current)
Q:The specific steps and procedures for installing the transformer
Oil-immersed or dry-type transformers are generally installed by the engineering team or factory installed do not know how much capacity your transformer is electronic or industrial power system
Q:Transformer noise reduction
Transformer noise is mainly caused by magnetostriction of silicon steel sheet. method: 1, choose a reasonable magnetic density; 2, core clamping; 3, pad to take shock measures; 4, the tank within the parts fastening, does not allow loose metal parts or standard; 5, all the accessories on the tank must be tightened; 6, the use of low noise fan; 7, the installation of the basic level. Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important
