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: Why should lighting transformers be used in factories and mines?
In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.
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: The transformer zero line has broken, has the result to the household illumination circuit?
When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage
Q: How many A leakage protection switches are used in 5000VA lighting transformers?
Line lighting transformer is suitable for AC circuit of 50~60 (Hz). It is widely used in electronic industry or industrial and mining enterprises, mechanical equipment, general circuit control power supply, safety lighting and indicator light power supply.
Q: Does the lighting work properly? Doesn't that power equipment start voltage unstable?
It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.
Q: How is the lighting power of the 380V transformer calculated?
With a light bulb with 4KVA load, the premise of the distance can be Mrs. face light bulb, dark can light the best load, 3KVA bulb brightness
Q: Power and lighting transformers, lighting quality will be affected much?
The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.
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: 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.
