- Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
- Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.
- Q:How is the lighting power of the 380V transformer calculated?
- Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, filament, cold resistance and simultaneous startup factor, it is better to choose the 400VA transformer
- 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:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- The transformer that power supply company manages, it is to supply motive power and illumination generally, namely the lighting transformer that does not have special illumination to illuminate. Units of their own transformers, is generally the case. The utility model has the advantages that the transformer and other equipment can be fully utilized, the efficiency is high, and the external power supply circuit does not need to be divided into power transmission lines and lighting circuits, and is simple and orderly, and the cost is low. As for the price of electricity, it is usually negotiated a power and lighting each percentage of the electricity to calculate and receive.
- Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- Now is the three standard power supply, fire, fire and a single, zero line is three 220V, the fire is 380V. 40W lights can be 25.
- 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: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:What type of low voltage transformer should be adopted for safety lighting power supply?
- We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!
