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: 1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires: First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high

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: The transformer zero line has broken, has the result to the household illumination circuit?: The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.

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: How many A leakage protection switches are used in 5000VA lighting transformers?: Secondary current =5000VA/220=22A, you can select the 32A leakage protection switch.

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: 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: 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: 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!
