- Q: Who knows how big transformers and lines the 36V transformer uses in lighting?
- Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.
- Q: Why should lighting transformers be used in factories and mines?
- There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
- 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: 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: 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)
- Q: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.
- 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: Power and lighting transformers, lighting quality will be affected much?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.
- 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 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..
