Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.
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:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?
The bulb is used in the two luminescence tube combined type lamp holder, the calculation process is very complex. Different combinations, the secondary voltage is different. Because it is a DC ignition, but also consider the efficiency of rectification, but the total power is constant.
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:Our power lines and lighting lines are connected to the same transformer. Is there any effect?
As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.
Q:What's the function of the lighting transformer?
Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.
Q:The transformer zero line has broken, has the result to the household illumination circuit?
No, the zero line of the transformer doesn't go through the zero line of the transformer. It is a star connection, and the center point is zero line
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 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:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.
