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?

See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W

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

There is only bus in the substation, and the station is connected with the transformer from the bus. If there is no electricity even in the bus, then the substation should not be considered active.

Q:What type of low voltage transformer should be adopted for safety lighting power supply?

Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.

Q:Why should lighting transformers be used in factories and mines?

But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?

Power lines and lighting lines are connected to the same transformer, without affecting the use of a transformer power users, lighting and power are connected together.

Q:What's the function of the lighting transformer?

Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.

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

The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer

Q:Can the 500 volt lighting transformer be changed into an electric welder?

500 VA transformer should not be used as an electric welding machine, so it is very difficult to reform the system, so it is better to buy a new electric welder

Q:The difference between lighting transformers and control transformers

Lighting transformer voltage is generally rated by a group or two setsControl transformers have many levels of output voltage
