- 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: Why should lighting transformers be used in factories and mines?
- In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.
- Q: Is the substation separate from the power and illumination transformer?
- The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.
- Q: How many A leakage protection switches are used in 5000VA lighting transformers?
- It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.
- Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
- Double winding type safety isolating transformer is provided with two windings respectively as input and output (primary) winding (secondary) winding, and between the two windings are insulated from each other, only through the magnetic connection to the power supply, which is the secondary winding and the earth does not constitute a loop, if the use of additional electrical insulation, it should be safety isolating transformer.
- Q: Power and lighting transformers, lighting quality will be affected much?
- First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.
- Q: Why can't autotransformer be used as transformer for safety lighting?
- The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
- Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
- The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the 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: How to calculate the rated capacity of small transformers for lighting purposes?
- Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.
