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:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
First look at this lamp,.24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sunThe power supply comes from the generator or battery, and the mode of operation is to ignite by alternating current and direct current. In comparison with the power supply of the transformer, the method of alternating current ignition is better to save the cost and reduce the cost
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: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: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: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: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:How to calculate the rated capacity of small transformers for lighting purposes?
In view of the power [kVA] conversion of each load, multiplied by the amount of consumption, according to the importance of the load, equipment location, voltage statistics, set the load line and load place of plastic case transformer capacity and its connection position. The future load power equipment shall be judged on the basis of prior installation or consideration of the economy in terms of equipment addition, installation, etc..
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?
Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.
