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

The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.

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

You must know the quantity and power of the lamp to determine the transformer

Q:How to calculate the rated capacity of small transformers for lighting purposes?

Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.

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

As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.

Q:How many A leakage protection switches are used in 5000VA lighting transformers?

AC circuit transformer for lighting lamp is suitable for 50-60Hz, is the power supply with safety shell low-voltage safety lights, can choose 220V or 380V power supply input voltage: 0V, 220V, 380V, 0V, 6.3V, output voltage: 12V, 24V, 36V.

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

The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator

Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?

Line light for safety light, voltage 24 volts and 36 volts, pay attention to the bulb and transformer voltage matching.

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

Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A

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.
