- 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:How is the lighting power of the 380V transformer calculated?
- The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator
- 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:How many power illuminator can 5Kva 36V transformer drive?
- By formula: P=UI COSAThat is, the transformer capacity is S=UI=5KVAHow big is the COSA?. Look, what kind of illuminator do you use?. Usually take 0.8-0.9It can be calculated that P is about 4KW-4.5KW (general lighting)
- Q:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- Power lines and lighting lines are connected to the same transformer, without affecting the use of a transformer power users, lighting and power are connected together.
- 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:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)
- Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
- To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
- Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, filament, cold resistance and simultaneous startup factor, it is better to choose the 400VA 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)
