Q:How many power illuminator can 5Kva 36V transformer drive?

The load capacity of the transformer is 70% of its nominal power, so it is concluded that the transformer you provide can drive the 3.5KVA 36V lighting appliance (which is used in normal condition and environment)

Q:What type of low voltage transformer should be adopted for safety lighting power supply?

In general, indoor transformers are used in general practice

Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires

First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high

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: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 A leakage protection switches are used in 5000VA lighting transformers?

According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.

Q:How is the lighting power of the 380V transformer calculated?

Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.

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:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40

Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.

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
