Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
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:Transformer fever how to do?
 Equivalent aging principle is the transformer in the part of the running time of the winding temperature is lower than 95 ℃ or underload, then in another part of the time can make the winding temperature higher than 95 ℃ or overload, as long as the overload time more than the life of life is equal to Transformers in the under-load time less loss of life, both offset each other, it can still maintain a normal life.     Transformer insulation aging six degrees principle:     When the transformer winding insulation temperature in the range of 80 ~ 130 ℃, the temperature rise of 6 ℃, the insulation aging rate will be doubled, that is, the temperature rise of 6 ℃, the insulation life is reduced by 1/2, which is insulation aging "Six Degrees".
Q:50KVA transformer each phase current maximum band
Normal current does not exceed 72A per phase current. Of course, in the event of an accident or to strengthen the transformer cooling can be short-term overload operation.
Q:Transformer ONAN?
ONAN refers to the natural cooling of oil. Common have the following cooling methods: Oil immersion (ONAN); Oil - air - cooled (ONAF); Forced oil circulation air conditioning (OFAF); Forced oil circulating water cooling (OFWF); Forced to guide oil circulation air cooling (ODAF); Forced to guide the oil circulating water - cooled ODWF).
Q:Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?
Transformer under natural cooling conditions, the maximum capacity of 500kVA, air-cooled conditions, the maximum 750kVA A refers to air, N refers to the natural cycle, F refers to forced circulation
Q:The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
The ideal transformer reflection impedance is the equivalent impedance of the load resistance equivalent to both ends of the primary coil, directly across the primary coil at both ends, in parallel with the primary circuit, and the nature of the reflection impedance and load impedance of the same nature.
Q:Can the transformer oil be used as a lubricant?
Transformer oil can not be lubricating oil, because the main role of transformer oil insulation is not lubrication. The main role of transformer oil: (1) insulation: transformer oil has much higher than the air insulation strength. Insulation material immersed in oil, not only can improve the insulation strength, but also from the erosion of moisture. (2) heat dissipation: transformer oil specific heat, often used as coolant. Transformers run the heat generated close to the core and the winding of the oil heat up and down, through the oil up and down convection, heat dissipated through the radiator to ensure the normal operation of the transformer. (3) arc suppression effect: In the oil circuit breaker and transformer on-load regulator switch, the contact will produce an arc switch. As the transformer oil thermal conductivity is good, and in the arc under the action of high temperature can touch a lot of gas, resulting in greater pressure, thereby enhancing the dielectric arc performance, so that the arc quickly extinguished.
Q:Rectifier and rectifier transformer
The rectifier is a device that turns AC into a DC. Rectifier transformer is to provide the rectifier with the corresponding AC input power. Rectifier transformer is done AC / AC conversion, and rectifier is done AC / DC conversion.
Q:Transformer 1KVA can load how much security, how to calculate the formula
This is based on the voltage count, such as three-phase 380V. 1KVA current is basically 1.5A
Q:Inverter with transformer and transformer without the difference
Specific differences: 1 inverter in the transformer is mainly from the role of pressure, is to make the power can be issued directly to the low-voltage power grid. Single-phase transformer is the transformer to 230V or so, slightly higher than the electricity single-phase power; three-phase change to about 400V, is also slightly higher than the electricity three-phase power 2 some transformers in addition to the role of isolation and isolation, the inverter is dependent on IGBT power devices to inverter, these power devices will produce more 3 harmonics and 3 times the number of harmonics, these harmonics on the grid Pollution is more serious, plus the isolation transformer (once for the triangular connection, the second star connection) can effectively filter 3 times 3 times the harmonic. 3 from the role of isolation is the abnormal situation when the grid will not put the inverter's important components burned. 4 plus the transformer certainly higher prices, the other weight increases, the efficiency will be slightly reduced.
