- 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!
- 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: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:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
- To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
- Q:Is the substation separate from the power and illumination transformer?
- There is only bus in the substation, and the station is connected with the transformer from the bus. If there is no electricity even in the bus, then the substation should not be considered active.
- 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:Power and lighting transformers, lighting quality will be affected much?
- Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer
- Q:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- Connect 220V method, FireWire 220V terminal, zero line 0 terminal, 380V terminal is not connected.Connect 380V method, A phase 380V terminal, B phase 0 terminal, 220V terminal is not connected.
- Q:Why can't autotransformer be used as transformer for safety lighting?
- The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous
- 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.
