Q:Is the substation separate from the power and illumination transformer?

The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.

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

You must know the quantity and power of the lamp to determine the transformer

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

In view of the power [kVA] conversion of each load, multiplied by the amount of consumption, according to the importance of the load, equipment location, voltage statistics, set the load line and load place of plastic case transformer capacity and its connection position. The future load power equipment shall be judged on the basis of prior installation or consideration of the economy in terms of equipment addition, installation, etc..

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?

Now is the three standard power supply, fire, fire and a single, zero line is three 220V, the fire is 380V. 40W lights can be 25.

Q:Why is the two side of the lighting transformer grounded?

Today's lighting products, regardless of the control system or the electronic power system itself, contain many semiconductorsComponents such as rectifier diodes, transistors, integrated circuits, LED, and so on. Semiconductor components are susceptible to staticElectrical damage, the two side of the power transformer grounding, help to produce a variety of factors, high pressure, residual static electricityDrain to avoid static electricity on the main circuit, to ensure product life.

Q:What transformer can be used in a safety voltage lighting transformer?

Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.

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

I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body

Q:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design

Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A

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:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.

A set of coils in a autotransformer having one tap that does not function as a barrier. Or, the two sets of coils are attached.
