Q:What is the vacuum impregnation of the transformer?
so that the transformer immersed in vacuum under the conditions of the paint, so you can rule out the bubble inside the winding, increase Insulation performance. Dip out after drying.
Q:The main transformer is chosen in principle
Transformer selection, you can refer to the following, but still according to the actual production needs! 1, the number of transformers to determine    (1), the number of main transformer to determine the principle is to ensure the reliability of power supply. When one of the following conditions is met, two or more transformers shall be installed.    ①, there are a lot of first-class load and although the secondary load but need to set from the security (such as fire, etc.).    ②, when the seasonal load changes greatly.    ③, when the load is large.    For large-scale hub substation, according to the specific circumstances of the project can be installed 2 to 4 main transformer.    When installing multiple transformers, it is appropriate to group the transformer according to the characteristics and changes of the load in order to flexibly switch the corresponding transformer group. Transformers should be operated in the sorted manner. Transformer low-voltage outlet of the neutral and neutral ground wire should be laid separately. For the convenience of testing, in the ground circuit, close to the transformer to do a removable connection device.    (2), the general three-level load or capacity is not too much power and lighting should be a load with only one transformer.    (3), when any of the following circumstances, can be dedicated transformer    ①, when the lighting load is large or power and lighting using a common transformer seriously affect the lighting quality and lamp life, can be set for lighting special transformer.    ②, single single-phase load is large, should be set single-phase transformer.    ③, the impact of a larger load, seriously affect the power quality, can be set for shock load special transformer.    ④, when the seasonal load (such as air conditioning equipment, etc.) about the total load of the project 1/3 and above, it is appropriate to configure a dedicated transformer.
Q:How to increase the transformer output current
2, Transformer (Transformer) is the use of electromagnetic induction to change the principle of AC voltage 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:What is the reason why the dry transformer is loud
500kva below the dry-type transformer noise 56 to 58 dB or so, 630kva above 62 to 65 dB or so! This is our factory data. The dry-type transformer sound is great. Big like cattle called the same, because the core is loose!
Q:What is the SN on the transformer? What is the difference between it and the actual power of the transformer?
Corresponding to the line of fire and the zero line, there is a L is the ground
Q:Transformer ONAN?
Transformer ONAN cooling method for the internal oil natural convection cooling, that is commonly referred to as oil-immersed self-cooling. 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.).
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:Why the computer water does not use transformer oil
In terms of cooling medium, the cooling effect of water is very good, it is used in the weak is the most used to achieve the purpose of cooling and the lowest operating costs.
Q:Power transformer primary current and secondary current
Once refers to the power side, the second refers to the load side
