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 lighting circuit mostly 3 phase unbalanced load, there will be zero drift, zero if the transformer line is broken, part of the lighting circuit to form a series of equipment in the case of two-phase circuit, circuit voltage is decreased and the lighting brightness is not enough, circuit voltage increases, the lamp burned;

Q:Why should lighting transformers be used in factories and mines?

There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.

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

But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.

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

It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.

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

220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.

Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40

I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body

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

Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.

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

General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)

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

Double winding type safety isolating transformer load end and the power supply terminal is not connected, is safe, and autotransformer primary winding of a share, it is directly connected with the power supply end of the power, not safety.
