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

220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.

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?

In general, indoor transformers are used in general practice

Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires

First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high

Q:How is the lighting power of the 380V transformer calculated?

Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.

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?

Is that the kind of 220V change 36V ah, if it is that kind of thing, I think it should be for security reasons. After all, 36V is a safe voltage. The damage to humans is slightly smaller than that of 220V.

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

The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage
