- 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?
- 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: 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: How many A leakage protection switches are used in 5000VA lighting transformers?
- According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.
- 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: How is the lighting power of the 380V transformer calculated?
- With a light bulb with 4KVA load, the premise of the distance can be Mrs. face light bulb, dark can light the best load, 3KVA bulb brightness
- Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
- Double winding type safety isolating transformer load end and the power supply terminal is not connected, is safe, and autotransformer primary winding of a share, it is directly connected with the power supply end of the power, not safety.
- 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: Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.
- Q: How to calculate the rated capacity of small transformers for lighting purposes?
- If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.
