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.
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: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:What's the function of the lighting transformer?
In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!
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: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:How many 40W bulbs can be brought into the 1000VA lighting transformer?
The key is that the 220V terminals and 0 can not provide 1000VA capacity?
Q:How many power illuminator can 5Kva 36V transformer drive?
Of course, if you want to bring more is not impossible, but depends on the working conditions, the actual power = nominal power, short time use (to ensure that the transformer temperature rise is not too high) is also available
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: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.
We are now looking forward to your kind cooperation, and will be highly appreciated for that. We sincerely hope to cooperate with you in the lighting field. Please don't hesitate to contact us at your convenience.
