Q:transformers and why they heat?
Of course a transformer must use AC voltage and current. Power consumed is calculated as P EI (volts x current). Even if the transformer is not connected to a load current must pass through the coils of wire. Although the resistance of the wire coils is minimized (where thick copper wire has less resistance) to obtain the needed effect many turns are required and thick wire may not be practical. The transformer will exhibit a heating effect equal to its I2R (current squared x resistance) losses.
Q:Is the secondary current rating of the transformer line current or phase current?
For star-wiring products, the line current = phase current For triangular wiring products, the rated current refers to the line current (phase to phase current)
Q:Transformer sales channels
1. Power supply company tender 2. Cabinet manufacturers 3, the installation company 4, direct customers, to the planning bureau to find, in advance to know which new project 5, design institute, know some late 6. Power supply company front desk, people come to install more late
Q:What does S11-M-500/10 transformer mean?
Three-phase oil-immersed transformers, 11 series capacity of 500KVA, from 10KV variable 400V transformer
Q:Transformers 2: Revenge of the Fallen?
The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots believing that peace was possible finds out that Megatron's dead body has been stolen from the US Military by Skorpinox and revives him using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots with reinforcements of their own, may have more to deal with then meets the eye. I'd take that with a pinch of salt though as it's probably fan invented.
Q:why are power transformers rated by KVA(kilovolt- ampere) instead of kilowatts?
With alternating current (AC) it is possible for the current and voltage to be out of phase. When they are exactly in phase KVA and KW are the same. If they are completely out of phase, the KW will always be zero regardless of how high the KVA is. Homes are usually billed only for KW. Commercials users are billed for a combination of KW and KVA.
Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means
Hello! Transformer high voltage, medium pressure, low voltage, respectively, refers to the three groups of winding (rated) voltage level. For example: 220kV voltage level of the transformer: the 220kV high voltage side, 110kV pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. Depending on the needs of the manufacturer, manufacturers may also be required to produce windings for other voltage classes. Such as: by the 220kV high voltage side, 35kV in the pressure side, 10kV low voltage side of the three groups of voltage levels of the composition. 500kV voltage level of the transformer: generally by the 500kV high voltage side, 220kV medium voltage side, 35kV low voltage side of the three groups of the composition of the voltage level winding.
Q:Transformer parameter interpretation
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 reactive power compensation of the transformer?
The use of capacitors to compensate for reactive power, improve the transformer's active power output capability.
Q:Taiwan, Taiwan, the concept of transformer
Transformer refers to equipment; Taiwan change is installed in a place of the transformer, is specifically installed, running a transformer; Taiwan area refers to the regional range of variable power supply. Metering point is for the two sides to determine the installation of electric energy meter position, in general, the measurement point should be set at the demarcation point of property rights.
