Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.
Q:Why should lighting transformers be used in factories and mines?
There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
Q:How is the lighting power of the 380V transformer calculated?
The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator
Q:The transformer zero line has broken, has the result to the household illumination circuit?
No, the zero line of the transformer doesn't go through the zero line of the transformer. It is a star connection, and the center point is zero line
Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.
Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
The key is that the 220V terminals and 0 can not provide 1000VA capacity?
Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
380V-220V/36V transformers, commonly known as safety transformers or line transformers, are mainly used for lighting in shop equipment and mobile lighting for inspection and maintenance. Their power is 50W, 100W, 200W, 300W., and their line size is determined by power!
Q:Why is the two side of the lighting transformer grounded?
Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..
Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.
