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

The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.

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: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:What transformer can be used in a safety voltage lighting transformer?

An isolated transformer is a transformer that is electrically isolated from an input winding and an output winding. The isolated transformer is used to avoid accidental touching of the charged body at the same time, and the isolation of the transformer is to isolate the current of the former side winding coil.

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

Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.

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: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:The difference between lighting transformers and control transformers

In principle and construction, there is no difference between the two.The only difference is that the secondary coil output voltage is different.
