The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute
It can last 1 minute at the rated current of two times
Wave form Distortion
No additional waveform distortion
it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
≤1s(in the condition that the external voltage changes is 10%)
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.
- 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:Why is elevator lighting transformer installed?
- 9.4.5 well distribution shall comply with the following requirements:1 the elevator hoistway shall be dedicated to the elevator, and no equipment, cables and other devices related to the lift shall be installed in the hoistway.2 the well shall be provided with illumination, and the illumination shall not be less than 501x, and shall comply with the following requirements:
- 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:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
- You must know the quantity and power of the lamp to determine the transformer
- Q:Power and lighting transformers, lighting quality will be affected much?
- The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.
- Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
- The sectional area of the wire can be calculated according to the electric power formula. The current required by the wire is calculated, and then the reference to the national standard "500 volt copper core insulated wire, long term continuous load allowable ampacity meter" is selected.
- Q:Why is the two side of the lighting transformer grounded?
- Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..
- Q:What transformer can be used in a safety voltage lighting transformer?
- Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.
- 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
