Q:How to test the transformer capacity
Temperature test is the main means of testing the transformer capacity. Its purpose is to assess the transformer in the rated load working state or overload working conditions, the thermal state of the transformer and so on.  
Q:What are the technical parameters of the transformer?
Transformers in the provisions of the use of the environment and operating conditions, the main technical data are generally marked on the transformer nameplate. Mainly include: rated capacity, rated voltage and its tap, rated frequency, winding connection group and rated performance data (impedance voltage, no load current, no load loss and load loss) and total weight. A, rated capacity (kVA): rated voltage. Rated current under continuous operation, can deliver capacity. B, rated voltage (kV): the transformer can withstand long hours of operation can withstand the voltage to meet the needs of the grid voltage changes, the transformer has a high voltage side tap, by adjusting the number of high voltage winding to adjust the low voltage side of the output voltage.
Q:What is the difference between the inverter and the transformer?
The inverter is based on a set of thyristor inverter, learn SCR inverter AC speed control circuit, is this principle. But in its protection circuit, variable frequency drive and so are controlled by the microprocessor, the input command, the output control can display. It is the implementation of the inverter circuit, the internal procedures are CPU, RAM, ROM storage and instructions, but also through the button for some functions of editing. In fact, is reliable output of the exchange of equipment he wants to ensure that the output voltage frequency are qualified Transformer is to change the voltage of the device is like 220 kV substation to 110 kV, 10 kV and then to 220 volts that we usually use the electrical conversion equipment.
Q:Transformers, broken, how to repair
You can first check the insurance, if only insurance problems, you can short-term insurance; the other can buy a replacement of the same specifications, the coil can also be broken coil rewind.
Q:Why is the notebook computer transformer hot?
Summer transformer is very hot, the notebook's own heat is more important to keep the room temperature the most important, too high temperature, then no matter how cool! Open the airplane with a laptop! At the same time should try to make the bottom of the notebook overhead, can be used special cooling bracket or with equal thickness and small size items (such as chess pieces, military flag, laminated one dollar coins, tape boxes, etc.) the bottom of the notebook pad! Try not to use the key film, because the keyboard is an important part of the notebook cooling! Other parts of the cooling (each brand of notebook cooling parts may be different) should not have object coverage! Summer is up, the notebook needs your double care Oh!
Q:What is the power transformer, what is the rectifier transformer
Rectifier transformer is isolated transformer, is often used in the power distribution cabinet to do the power.
Q:What is the primary side of the transformer
Explanation: The primary side refers to the input side of the voltage, and the secondary side refers to the output side of the voltage after the voltage is converted by the transformer. For the step-up transformer, the primary side is the low side, the secondary side is the high side; For the buck transformer, the primary side is the high side, the secondary side is the low side.
Q:Two Transformers Parallel Operation
After the parallel capacity can be provided is the sum of the capacity of the two transformers ---- If the two transformers capacity is the same, after the parallel capacity can provide the total capacity of the two transformers are the sum of capacity. If a 1000kva transformer and a 800kva transformer in parallel, the parallel can provide the total capacity of 1600kva. The distribution of load load and what principles, that is, how to allocate two transformer load capacity --- transformer parallel to meet the three conditions: 1, two transformer transformer ratio equal; 2, two impedance voltage equal; 3, two Transformer capacity should be as close as possible, should not exceed 3: 1. To meet these three conditions in parallel, the load is evenly distributed to two transformers.
Q:The difference between transformer power kva and kw
Kva is the unit of apparent power, KW is the unit of active power. Apparent power equal to the root number (active square square + reactive power square)
Q:What is the meaning of the transformer 'turns ratio'? what's the effect?
The turns ratio of the transformer is the ratio of the transformer, that is, the ratio of the turns of the original coil and the secondary coil. Role: reflects the original transformer, vice coil voltage RMS ratio. In the case where the no-load current is negligible, the magnitude of the original and secondary coil current is inversely proportional to the number of turns. 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.
