Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.
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: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: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 lighting power supply in the substation need not be separated. In a large capacity power plant, the lighting can be electrically powered to ensure that the generator is stopped. The lighting source is often separated from the lighting transformer and powered by other power supplies.
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
Q:Can the 500 volt lighting transformer be changed into an electric welder?
The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.
Q:How many power illuminator can 5Kva 36V transformer drive?
Transformer (Transformer) is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are voltage conversion, current conversion, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and so on. According to use can be divided into: power transformers and special transformers (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine, variable audio transformers, intermediate frequency transformers, high frequency transformer, transformer, instrument transformer, the impact of electronic transformer, reactor, transformer etc.). Circuit symbols are often used as the beginning of numbers. Examples: T01, T201, T, etc..
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
