Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.
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:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
Line light for safety light, voltage 24 volts and 36 volts, pay attention to the bulb and transformer voltage matching.
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:The difference between lighting transformers and control transformers
Lighting transformer voltage is generally rated by a group or two setsControl transformers have many levels of output voltage
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:Why can't autotransformer be used as transformer for safety lighting?
The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous
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
The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
Q:What type of low voltage transformer should be adopted for safety lighting power supply?
In general, indoor transformers are used in general practice
