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

First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.

Q:Why can't autotransformer be used as transformer for safety lighting?

When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!

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: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:Who knows how big transformers and lines the 36V transformer uses in lighting?

Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.

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:Why is the two side of the lighting transformer grounded?

In the three-phase transformer, the neutral point of the three-phase transformer and the metal case are always reliably connected, and the utility model has the advantages of reliable grounding, both working grounding, protection and earthing, and protection of personal safety and equipment safety.

Q:Why is elevator lighting transformer installed?

1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.

Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?

If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)

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.
