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:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?

First look at this lamp,.24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sunThe power supply comes from the generator or battery, and the mode of operation is to ignite by alternating current and direct current. In comparison with the power supply of the transformer, the method of alternating current ignition is better to save the cost and reduce the cost

Q:Why should lighting transformers be used in factories and mines?

But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

Q:How to calculate the rated capacity of small transformers for lighting purposes?

Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.

Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?

Connection mode:N circuit breaker is caused by breaker of outlet line of transformer main cabinet.The branch circuit breaker divides the power, the electricity and the lighting power.

Q:How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?

The key is that the 220V terminals and 0 can not provide 1000VA capacity?

Q:Why is elevator lighting transformer installed?

1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.

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.

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: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.
