- Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
- If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.
- Q:What type of low voltage transformer should be adopted for safety lighting power supply?
- In general, indoor transformers are used in general practice
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- The bulb is used in the two luminescence tube combined type lamp holder, the calculation process is very complex. Different combinations, the secondary voltage is different. Because it is a DC ignition, but also consider the efficiency of rectification, but the total power is constant.
- Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
- No matter how many volts the output / input voltage of the transformer is, the size and the amount of the core of the transformer, the wire diameter of the winding lead and the lead thickness must be determined by the transformer capacity. Example: input 220V, output 36V load is 36v/40w light bulb 6, so the primary needs 0.72, secondary use 1.81 diameter enameled wire winding system. The transformer capacity is about 250VA.
- Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?
- It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.
- 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?
- Because some transformers are connected to 380V and 0, they can be 1000VA capacity, but because of the same line diameter, the 220V terminals and 0 can not provide the capacity of 1000VA.
- 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: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:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
- Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A
- Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
- General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
