Q:What is the difference between the SGB10 transformer and the SC (B) 10 transformer?
1.SGB and SCB transformers are dry-type transformers, the former is non-encapsulated transformer, which is the package transformer, because the SGB is a non-encapsulated transformer, the coil is damaged, can be part of the maintenance; SCB is epoxy encapsulated transformer coil , If the coil burned only after the coil, not part of the maintenance 2. The former heat-resistant grade for the H-class, the latter for the F-class. 3. From the cost point of view, SGB10 than SCB10 expensive 4. From the service life, the basic almost.
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:KW how to know how much transformer?
Know the number of KW, how to calculate how much transformer is needed. In general, our calculation is based on the nature of the equipment, the production process, the development prospects of the production enterprises to analyze the size of the transformer, some companies, how many kilowatts to choose the number of KVA, and some enterprises have all the equipment must boot Run, then, on the choice of a little bigger, the machinery industry enterprises, generally in accordance with the installed capacity of 4-5 fold to select the transformer capacity. For reference only.
Q:Is the LTC transformer a regulated voltage transformer?
OLTC (on load tap changer) On-load tap-changer NLTC (no Load tap changer) No load regulator The above two switch switches are used for transformer voltage regulation.
Q:Transformer insulation level L175 AC35 / 5 What does it mean
The voltage withstand voltage is 480kV, the power frequency withstand voltage is 200kV, the middle voltage side of the neutral point of the lightning impulse withstand voltage is 250kV, power frequency withstand voltage is 95kV; low side of the terminal side of the lightning Impact withstand voltage is 75kV, power frequency withstand voltage is 35kV; 3, "LI 75 AC 35" means that the 10kV transformer high voltage winding lead side of the lightning impulse withstand voltage is 75kV, power frequency withstand voltage is 35kV.
Q:250KVA transformer maximum load how much KW power?
The maximum load KW number is determined by the actual use of the power factor of the device because KVA is apparent power and KW is active power. If there is no reactive power in the load device, such as all incandescent lamps, Of the pure resistance of the device, the transformer can theoretically carry 250KW load, the actual use, because there are power lines on the reactive power exists, so the need for discount.
Q:50kva transformer price
You have a problem is the voltage level and model do not know, can not set the price. The capacity is 50 kVA. If it is 10000 volts change 400 volts S11 50 kVA is about 9,000 yuan, S9 7500-8000, S7 is about 7000.
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:What is the difference between the inverter and the transformer?
Literally speaking: the former is the conversion frequency, which is the conversion voltage. Structurally speaking: The former is a complex electronic device, the latter is relatively simple equipment. From the working principle speaking: Inverter: first input AC rectifier filter, the control circuit according to the needs of the output modulation signal, the signal control power output tube turn on and off (usually half bridge or full bridge), by changing the turn on and off time, The corresponding output frequency. Transformer: the usual sense of the transformer is composed of multiple coil winding and core components, in which one winding on the application of AC voltage, the other winding will produce the induced voltage, the voltage ratio for the winding turns ratio, The main frequency of the output frequency is the same as that of the input, and the harmonics are predominantly even.
Q:What are the ways of protecting the transformer?
Large transformer main protection is differential and gas, backup protection including temperature, quick overcurrent and so on!
