Q: How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?: 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: What type of low voltage transformer should be adopted for safety lighting power supply?: Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.

Q: The difference between lighting transformers and control transformers: The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.

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: 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: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)

Q: 3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?: Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.

Q: Does the lighting work properly? Doesn't that power equipment start voltage unstable?: 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: Can the 500 volt lighting transformer be changed into an electric welder?: The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.

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.
