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: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: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..
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 is the two side of the lighting transformer grounded?
Single-phase transformer two side lighting to the ground, on the one hand is the lighting products now contain many semiconductor devices such as diodes, transistors, integrated circuits, semiconductor devices vulnerable to electrostatic damage, two side grounding contributes to the surge pressure factors produced by residual electrostatic discharge stay in the main circuit, avoid electrostatic protection, product life. In the 21 aspect, there is distributed capacitance between the two side and the primary side of the power transformer, and the high frequency surge disturbance caused by the primary side current source will directly enter the two side to the main circuit through the distributed capacitor. These unnecessary high frequency interference may jump into the sensitive signal source, make the control system malfunction, and the two side grounding of the power transformer can eliminate most of the undesirable effects of the distributed capacitance.
Q:What's the function of the lighting transformer?
Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.
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:Can the 500 volt lighting transformer be changed into an electric welder?
The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft
Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)
Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.
We not only respond to current requirements, but we also anticipate their emerging needs. We warmly welcome customers from all over the world to contact us and establish business relationships for a better future.
