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: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.
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: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 should lighting transformers be used in factories and mines?
But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""
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:Power and lighting transformers, lighting quality will be affected much?
First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.
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: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 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
