 Q:Transformer is the transmission of electrical equipment
 The transformer is an electrical device that converts the AC voltage level to achieve the purpose of power transmission.
 Q:How to use a multimeter to determine the quality of small transformers
 Generally with the smallest ohm file to measure whether the primary tap, if not, then damaged. Use the X10K stall above the ohm stalls to measure the primary and secondary, primary secondary and iron core for short circuit or leakage. If there is connectivity, then the insulation is bad or has been burned or breakdown.
 Q:What is the meaning of the high voltage side and the low side of the transformer?
 Under normal circumstances the role of the transformer is to highvoltage transmission (saving material to reduce the loss) over the power to reduce the voltage (there are boost in the power plant substation) to meet the conventional use of electrical equipment standards. Therefore, in the conventional stepdown transformer input (also called once) is the highpressure side, the output (also called the second) is the low side.
 Q:630KVA transformer can use the maximum number of power appliances
 General transformer power factor is 0.85 or so 630X0.85 = 535.5KW, you should be installed capacity of 590KW, if it is not necessarily open at the same time, there is no problem. On the contrary, you can also increase the capacitor to improve the power factor to run .300KW If not more than 150 meters, then available 3X120 +50 copper cable, the distance from the increase in the line by.
 Q:What is the difference between transformers and inverters?
 Transformer is the same frequency of a voltage into another level of voltage, such as the (frequency 50hz) 10kv into (power frequency 50hz) 400v. The inverter can convert DC into any frequency (there are many types of inverter, the output voltage frequency range is different) AC but the voltage level will not change.
 Q:Which is good for the transformer?
 JMBBZBJZ line lighting transformer, JBK machine control Transformer, SSG Servo Transformer, Low Voltage High Current Heating Transformer, SBW High Power Compensated Power Regulator, SBWF Splitter Regulator, SVC High Precision Fully Automatic AC Voltage Regulator, Precision Clean Regulator, Microcomputer No Touch Point voltage regulator, UPS, EPS power supply, KSG mine transformers, DN resistance welding watercooled transformers, reactors, contacttype automatic voltage regulator, column highpower electric voltage regulator,
 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
 Q:What is the difference between AC transformers and DC transformers?
 DC transformer to change the voltage first to use the electronic components of the DC current into alternating current, and then transform the voltage with the transformer. This device is called the inverter.
 Q:Transformer ratio and transformer ratio
 Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship!
In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1
 Q:Will the 250KVA, 500KVA, 630KVA Van transformer size,
 250KVA, 500KVA, 630KVA Van transformer size, size: length 4.6m, width 2.5m, 2.4m high.
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). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, drytype transformers, oilimmersed transformers, singlephase transformers, electric transformers, rectifier transformers.
