- Q: 80 kilowatts of electrical appliances need much transformer?
- 80 kilowatts of electrical appliances need 100kVA transformer. 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: TN-S system in the transformer neutral point that pe line and n-line neutral point how to take? N line and pe line in the neutral point on the connected, and then ground the same ground? Or that n line from the neutral point out of their own then a pe line then one after another? If the neutral point out of the ground, in the three-phase imbalance when the n-line current?
- TN-S way power supply system It is the work of the zero line and dedicated protection line PE strictly separate power supply system, N line and PE line in the transformer working ground once separated, not to re-connect. Called TN-S power supply system. The TN-S power supply system is characterized as follows. 1) When the system is running normally, there is no current on the dedicated protection line, but there is an unbalanced current on the working zero line. PE line to ground no voltage, so the electrical equipment metal shell connected to zero protection is connected to the dedicated protection line PE, safe and reliable. 2) The working zero line is used only as a single-phase load circuit. 3) Dedicated protection line PE is not allowed to break, but also not allowed to enter the leakage switch. 4) the use of leakage on the trunk protection, the work of the zero line shall not have repeated grounding, and the PE line has repeatedly grounded, but not through the leakage protection, so TN-S system power supply lines can also be installed on the leakage protection. 5) TN-S power supply system is safe and reliable, suitable for industrial and civil construction and other low-voltage power supply system. In the construction work before the "three links and one leveling" (Dentsu, water, road and ground level - must use TN-S way power supply system.

- Q: I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?
- Never attempt to prise apart sealed units.There is a risk of explosion.
- 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: What is the normal color of the transformer oil?
- From the oil color depth can also be a rough understanding of the degree of oil refining and oil after the use of deterioration. Good quality
- Q: How do I choose a transformer? The
- Select the transformer, you can not choose too large, can not choose too small According to the following method to select the transformer capacity. ???There is a very important data is not provided, is the load at the same time coefficient. Transformer with the actual load and equipment rated power ratio is called the transformer load factor. The concept of the load factor for the load is the probability that the load is used at the same time, also called the coefficient or the simultaneous coefficient, which is the probability of simultaneous use of the device. The total load is 300kw, but they are used at the same time there is a probability that the probability is the load factor. It is impossible to always use at the same time. Of course, you can according to the actual situation to calculate their own, power factor selected 0.80. ??With this formula, s = p * kX / cosφ Transformer capacity s = device rated power p × transformer load rate kx / power factor cosφ = (300 × kX) × 0.80 This is the transformer capacity. ???Do not know what the motor is used under the circumstances, so it can not be calculated, and only calculate the same time after the generation of the formula into the above formula. If the coefficient is 0.9, then the results of about 340 kVA, are used at the same time, that is, 375KVA, consider a certain margin and spare capacity, that can choose 400KVA. In addition to the above considerations, in particular, consider the motor starting current factor, select the transformer more reliable. As far as possible by the big do not rely on small. And the standard capacity of the transformer level 315,400,500,630KVA, 315KVA a little small, 500KVA big and no need. So choose 400kvA it
