Q:How many power illuminator can 5Kva 36V transformer drive?

Of course, if you want to bring more is not impossible, but depends on the working conditions, the actual power = nominal power, short time use (to ensure that the transformer temperature rise is not too high) is also available

Q:Power and lighting transformers, lighting quality will be affected much?

The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.

Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?

If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.

Q:Is the substation separate from the power and illumination transformer?

The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.

Q:The transformer zero line has broken, has the result to the household illumination circuit?

The lighting circuit mostly 3 phase unbalanced load, there will be zero drift, zero if the transformer line is broken, part of the lighting circuit to form a series of equipment in the case of two-phase circuit, circuit voltage is decreased and the lighting brightness is not enough, circuit voltage increases, the lamp burned;

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:How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?

Now is the three standard power supply, fire, fire and a single, zero line is three 220V, the fire is 380V. 40W lights can be 25.

Q:How many A leakage protection switches are used in 5000VA lighting transformers?

According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.

Q:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design

Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.

Double winding type safety isolating transformer is provided with two windings respectively as input and output (primary) winding (secondary) winding, and between the two windings are insulated from each other, only through the magnetic connection to the power supply, which is the secondary winding and the earth does not constitute a loop, if the use of additional electrical insulation, it should be safety isolating transformer.
